EXECUTIVE SUMMARY

A Tier 3 human health risk assessment (HHRA) was performed in accordance with the approved Tier 3 Risk Assessment Work Plan (Work Plan) and approved Technical Memoranda #4 and #5 for thirty-six Solid Waste Management Units (SWMUs) and Areas of Concern (ADCs) designated by the Amended Consent Agreement and Final Order (2000, amended 2012 and 2015) at the CHS McPherson Refinery at McPherson, Kansas. SWMUs and AOCs were grouped into nineteen exposure areas (EAs) for quantitative assessment. The results of the Tier 3 HHRA provide the following conclusions.

• Based upon a screening analysis performed using conservative screening levels and standards published by USEPA and KDHE (where appropriate), the following constituents of potential concern (COPCs) were identified for Tier 3 risk evaluation:

- Surface and subsurface soil COPCs include primarily polycyclic aromatic hydrocarbons (PAHs) and petroleum mixtures;

- Surface water COPCs include a limited list of metals, PAHs, and volatile organic compounds (VOCs);

- Sediment COPCs, due to screening based solely on detection status, were numerous and consisted of metals, VOCs, semi-volatile organic compounds (SVOCs), and petroleum mixtures; and

- Soil vapor COPCs include benzene, ethylbenzene, toluene, xylenes, and naphthalene.

• Potential receptors at the site include the industrial site worker, utility worker, construction worker, and recreational receptor. The recreational receptor is present only in areas outside of the operating refinery units.

• Cumulative carcinogenic risk and non-carcinogenic hazard indices were estimated for the potential receptors relevant for each of the 19 EAs.

• Carcinogenic risk and non-carcinogenic hazard estimates for potential multimedia exposure for the industrial site worker and recreational receptor were within the target cumulative carcinogenic risk range of 1x10- 6 and 1x104

and target non-carcinogenic hazard of 1.0 at all EAs.

• Carcinogenic risk or non-carcinogenic hazard estimates for potential multimedia exposure during intrusive activity for the utility worker and construction worker exceeded the target values in EAs 5, 7, 8, 9, 10, and 11. The primary constituents contributing to the estimated excess risk or hazard were petroleum mixtures in soil (EA 5, 7, 8, and 11) within 10 feet below ground surface, and volatile constituents in soil vapor within the same interval during hypothetical trenching activity (EAs 9 and 10).

• While historical impact to the underlying ground water is apparent, COPC concentrations reported in soil and sediment for the EAs were not estimated to further result in partitioning/migration to ground water at concentrations above residential drinking water standards based on multiple lines of

Vii \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

evidence. The analyses supporting this conclusion included partitioning estimates, site-specific modeling of vertical attenuation, vertical profile of measured constituent concentrations, and leachate analysis of select samples and constituents. CHS recognizes that historical NAPL releases form the more significant source for ground water impact at the site.

• Ground water is presumed to be impacted above target risk levels based on the presence of light non-aqueous phase liquid (LNAPL) on ground water, which has been and continues to be addressed through robust and ongoing interim corrective action, monitoring, and reporting.

• Additional CI activities following completion of this HHRA include activities related to evaluation of indoor air and NAPL delineation at EA 8, to be submitted separately. No other CI activities appear to be warranted for the identified SWMUs and AOCs.

• A Corrective Action Study (CAS) will be prepared following approval of this HHRA, and will address the findings of potential excess carcinogenic risk and non-carcinogenic hazard. In addition, the scope of the CAS will include addressing soil areas containing NAPL, development of corrective action objectives/remediation goals, and final remedy for ground water.

1.0 INTRODUCTION

CHS McPherson Refinery Inc. (CHS) has prepared this Tier 3 Human Health Risk Assessment (HHRA) for the CHS Refinery at McPherson, Kansas (hereinafter the Refinery; Figure 1-1) following the Kansas Department of Health and Environment (KDHE) approval of the following documents submitted for the Refinery in support of the Tier 3 HHRA:

• Risk-Based Screening Evaluation (RBSE);

• Tier 3 Risk Assessment Work Plan;

• Data Gap Sampling Event Summary Report; and

• Tier 3 Risk Assessment Technical Memoranda #1 through #5.

This Tier 3 HI-IRA fulfills part of the requirements of the Amended Consent Agreement and Final Order (CAFO), with the Kansas Department of Health and Environment (KDHE, Case No. 00-E-0190, executed December 31, 2012 and amended December 31, 2015) for completion of a comprehensive investigation and risk assessment of certain select solid waste management units (SWMUs) and areas of concern (ADCs) at the Refinery. The Amended CAFO replaces the Consent Order executed December 2000.

The purpose of the Tier 3 HHRA report is to describe the objectives, technical approach, scope of work, results, and conclusions for the human health risk assessment. The Tier 3 HHRA addresses media, constituents, and potential exposure pathways identified in the RBSE as warranting further evaluation, as well as pathways specifically requested by KDHE and the USEPA. Constituents and potential exposure pathways were further assessed following the RBSE with delineation sample results from the data gap sampling. The results of the data gap sampling are combined with prior sampling results to address the comprehensive data set in this HHRA.

1.1 FACILITY BACKGROUND AND DESCRIPTION

The Refinery is located at 1391 Iron Horse Road, McPherson, Kansas (Mailing/Office Address is 2000 South Main Street, McPherson, Kansas), and comprises approximately 320 acres of a 1250 acre property owned by CHS, formerly National Cooperative Refinery Association (NCRA). Approximately 32 acres were obtained in 2013 via purchase of the neighboring property from El Paso Corporation; a risk assessment for the El Paso parcel will be performed separately following a methodology agreed upon by KDHE and CHS. Refinery operations began in 1933 and the facility operates continuously, processing approximately 80,000 barrels per day, with the exception of periodic shut downs for repair and maintenance. Crude oil is supplied to the Refinery primarily by pipelines. A small quantity of mixed oil products is delivered by truck. The Refinery produces several consumer fuel products including gasoline, diesel fuel, propane, fuel oil, residual oils, and coke. Figure 1-2 shows the site layout.

1.2 REGULATORY FRAMEWORK

In the initial Consent Order (effective December 2000), a total of 40 units (32 SWMUs and eight AOCs) were listed for the Refinery. Since the executed date of the initial Consent Order, the list of units at the Refinery requiring further action has been amended. CHS identified an additional SWMU (SWMU No. 33, Pitch Pit) north of Bull Creek in 2002. A total of 44 SWMUs and AOCs (including SWMU 31A-D and SWMU 33) were identified for investigation (see Appendix A-1). Figures 1-3 and 1-4 show the Refinery SWMUs and areas of concern AOCs.

Of the 44 identified SWMUs or AOCs, two SWMUs (06 and 22) were identified as requiring No Further Action in the Consent Order. Five SWMUs (05, 12, 16, 17, and 19) and one AOC (03) were approved as requiring No Further Investigation by the KDHE in a letter from KDHE to CHS dated September 16, 2002 (KDHE, 2002). The remaining thirty-six AOCs and SWMUs were included in the investigation phases of work and were designated for evaluation in a risk assessment.

The Amended CAFO, which replaces the Consent Order, has a requirement for a comprehensive investigation of the identified SWMUs and AOCs. CHS believes this requirement has been met with multiple phases of environmental sampling with results reported in the Comprehensive Investigation Report, Document 5, dated October 13, 2005, and the Data Gap Sampling Event Summary Report, dated November 14, 2013.

Additional supplemental soil vapor sampling near buildings was conducted in November 2015 in support of a vapor intrusion evaluation. The selected buildings are located on the eastern side of the property outside of the identified SWMUs and AOCs. The vapor intrusion evaluation is further discussed in Section 1.3.

The scope of this Tier 3 risk assessment addresses the SWMUs and AOCs listed in Appendix A-1. The descriptions of the SWMUs and AOCs in Appendix A reflect the initial designations at the time of investigation, and do not necessarily correspond to the current operational function of the area. For example, EA 5, which includes SWMUs 01 and 02, no longer contains the "old API separator" or "new API separator". Investigation activities, assessments, and submittals for other areas are addressed separately with KDHE.

1.3 PROJECT BACKGROUND

The initial quantitative risk assessment work for the Refinery was documented in the RBSE, dated June 30, 2010 and approved by KDHE and USEPA. In the RBSE, the 36 SWMUs and AOCs being investigated were grouped together to form 19 Exposure Areas (EAs) for risk evaluation based on proximity, use and worker activity patterns. The EA groupings were approved by KDHE and USEPA in a letter dated March 13, 2008. The EAs for the RBSE, which are carried forward


2 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

into the Tier 3 HHRA, are listed on Appendix A-2 and shown on Figure 1-5. The results of the RBSE were used as the starting point for identifying EAs (SWMUs/A0Cs) included in the scope of work for the Tier 3 HHRA.

The RBSE accomplished the following objectives:

• Identified constituents of potential concern (COPCs);

• Determined which EAs could be eliminated from further evaluation based on a comparison of soil data to conservative risk-based soil screening levels;

• Determined which EAs (SWMUs/A0Cs) required further site-specific risk evaluation;

• Prioritized EAs based on relative levels of risk; and

• Provided a focused approach for the path forward (next step).

As indicated in the RBSE, direct contact with ground water is considered a potentially complete pathway, and is presumed to pose excess carcinogenic risk and non-carcinogenic hazard. Ground water at the site is approximately 80 feet below ground surface. Exposure to site ground water during intrusive activities (e.g., utility or construction) is unlikely given the depth of the water table. There is no current use of ground water for potable purposes in the known affected areas. Ground water is pumped on-site and used for process water. There is active, on-going ground water remediation and monitoring of the affected zone at the Refinery. Applicable and relevant standards are being used to guide the ground water remediation strategy. Perimeter monitoring is performed routinely for indicator constituents and demonstrates that potential exposure pathways are incomplete for off-site receptors. KDHE and USEPA have agreed that a quantitative risk evaluation of direct contact with ground water is not required as part of the Tier 3 HHRA, and that corrective action objectives will continue to be addressed through annual monitoring and reporting activities. The final site-wide remedy for ground water will be presented as part of the Corrective Action Study, and may include technologies other than the ongoing Underground Oil Recovery system and ground water monitoring.

The results of the RBSE were also used to identify the need for additional site characterization in areas that were identified for further risk evaluation. The scope of work for additional site characterization was provided to KDHE and USEPA in a separate document (Data Gaps Sampling Program Work Plan, dated March 8, 2012). The "data gap samples" were analyzed for constituents consistent with previous investigations as well as hexavalent chromium and other supplemental constituents that provided information useful for risk characterization (e.g., hydrocarbon fractions). The results of data gaps sampling were summarized in the approved Data Gap Sampling Event Summary Report.

To address technical aspects of the Risk Assessment methodology and expedite the review process, a Tier 3 Risk Assessment Work Plan (Work Plan) was submitted to KDHE, consistent with the Amended CAFO. The Work Plan provided a


3 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

detailed technical approach for the Tier 3 HHRA. Detailed assumptions regarding exposure and toxicity that form the basis for quantitative risk calculations in the Tier 3 HHRA were submitted for approval in a series of Technical Memoranda. Technical Memoranda #1 through #3 provided methodology descriptions and values for data screening, receptor exposure, and receptor toxicity related to the ecological risk assessment for the Refinery. The Ecological Risk Assessment (ERA) Report, dated March 9, 2015, was submitted to KDHE and USEPA. CHS has submitted responses to comments regarding the ERA received from KDHE. KDHE approved CHS' responses in a letter dated December 22, 2015. The revised ERA will be submitted to KDHE in February 2016 in accordance with communications between KDHE and CHS following the approval letter.

Technical Memorandum #4 identified specific toxicity values for chronic and sub-chronic human health exposure. Technical Memorandum #5 presented a detailed evaluation of the Refinery background data set, statistical methods for evaluation, and calculation of background threshold values (BTVs) for the Refinery. Soil BTVs are informative for both human health and ecological risk assessments at the Refinery. Technical Memorandum #6 was submitted to KDHE and USEPA to summarize the preliminary vapor intrusion evaluation for the Refinery. Following receipt and consideration of comments from KDHE, additional sampling and evaluation were proposed in a Response to Comments that was approved by KDHE on May 29, 2015. The vapor intrusion evaluation for the Refinery will be submitted for approval separately as an Addendum to the Tier 3 I-H-IRA following the evaluation of soil vapor data collected in November 2015.

1.4 OBJECTIVES OF THE TIER 3 HHRA

Risk assessments are generally performed in the RFI process to determine whether current conditions at a site pose unacceptable risk to human health The results are typically used to: 1) support the conclusion of no further remedial action; 2) focus corrective action (i.e., prioritize remedial efforts); and 3) develop site-specific remediation goals for media of concern.

The primary objectives (goals) of the Tier 3 HHRA for the Refinery are to:

• Evaluate potential risk to human health considering site-specific conditions and potential exposure pathways;

• Identify SVVMUs/A0Cs that require no further action;

• Identify SWMUs/ AOCs that require corrective measure(s) and prioritize corrective action needs at units requiring action; and

• Provide the framework for developing site-specific remediation goals, where appropriate.


4 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

1.5 SCOPE OF WORK FOR TIER 3 HHRA

A Tier 3 HHRA was completed for SWMUs and AOCs identified as requiring further evaluation. The risk evaluation was conducted in accordance with procedures outlined in the Risk Assessment Guidance for Superfund [RAGS, (USEPA, 1989, 1991, 2004, and 2009)] and was performed assuming the absence of any controls or remedial actions to mitigate exposure or affected media.

The Tier 3 HHRA consisted of the following five components:

• Data evaluation and selection of COPCs;

• Exposure assessment;

• Toxicity assessment;

• Risk characterization; and

• Uncertainty analysis.

These major components are discussed in detail in subsequent sections of this report.

2.0 DATA EVALUATION AND SELECTION OF COPCS

This section describes the methods and results of additional data evaluation and screening performed as part of the Tier 3 HHRA. In addition, a summary of the data evaluation performed and presented in prior documents is provided for ease of review and to support an understanding of the full scope of the assessment.

2.1 COPCS FOR STANDARD EXPOSURE PATHWAYS

A data screening process was performed as part of the RBSE to identify COPCs for further risk evaluation and to eliminate those that may be excluded from further risk evaluation. Screening was performed for the soil direct/indirect contact pathways (for the site worker, utility worker, and construction worker) as well as the soil to ground water pathway. Direct soil exposure includes exposure via ingestion and dermal contact. Indirect soil exposure includes exposure via inhalation of vapors from volatile constituents in soil and inhalation of soil dust and particulates. Screening was also performed for surface water and sediment ecological pathways for AOC 02 and SWMU 09.

A screening process was performed on data collected in 2012 and 2013 as part of the Data Gap Sampling Program to confirm and include, where warranted, COPCs that should be retained for further evaluation for the soil direct/indirect contact and soil to ground water pathways. Data screening of 2012-2013 sample results was performed using the published USEPA Regional Screening Levels (RSLs, dated November 2013) to focus the risk assessment on those constituents that are likely to have the greatest potential impact on the overall risk of the site. The RSLs were based on a target carcinogenic risk of 1.0E-06 and non- carcinogenic hazard quotient of 0.1, consistent with target carcinogenic risk and non-carcinogenic hazard levels utilized in the RBSE. The results of the data- screening step were used to identify the final COPCs to be evaluated in the risk assessment for each medium of concern and EA for the soil direct contact, and soil to ground water pathways. Comparisons of data gap sample results to RSLs were previously presented in the approved Data Gap Sampling Event Summary Report. Appendix B-1 lists the COPCs identified from the data gap samples. COPCs not previously identified for a specific EA are highlighted, and are primarily PAHs, which is consistent with the COPC list for the Refinery as a whole. Cobalt was the only COPC not previously identified in at least one EA for the Refinery. Cobalt was added to EA 1 for the soil to ground water protection pathway. Appendix B-2 summarizes the final comprehensive COPCs for each EA and receptor for the standard exposure pathways of soil direct/indirect contact and soil to ground water.

2.2 COPCS FOR NON-STANDARD EXPOSURE PATHWAYS

Site-specific quantitative risk evaluations are performed for non-standard exposure pathways in this report. Screening was not performed in the RBSE for the following non-standard, site-specific exposure pathways:


7 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

• site worker exposure to vapors released from subsurface soil/ground water to ambient air;

• site worker exposure to pond water;

• site worker exposure to pond sediment;

• utility worker and construction worker exposure to vapors released from subsurface soil/ground water to trench air;

• construction worker exposure to pond water;

• construction worker exposure to pond sediment;

• recreational exposure to surface water in Bull Creek;

• recreational exposure to sediment in Bull Creek; and

• recreational exposure to soil at the former Pitch Pit.

Consistent with the approved Tier 3 Risk Assessment Work Plan, this report provides the results of a screening evaluation for a subset of the scenarios identified above, and the remaining scenarios were fully evaluated without completing a screening evaluation. Because published screening values were unavailable for the site-specific scenarios in general, CHS relied on conservative generic screening values to identify COPCs for the site-specific scenarios noted in the table below following completion of the Data Gap Sampling Program. For certain scenarios (e.g., incidental worker contact with sediment and recreational receptor contact with sediment) as noted below, directly relevant screening values were not identified and therefore screening was not performed prior to performing site-specific risk calculations. COPCs for these scenarios were established based on reported detection in at least one sample of the medium.

CHS utilized the following screening values with the comprehensive valid data set, consistent with the approved Tier 3 Risk Assessment Work Plan:

Scenario/Pathway Screening Method Site worker exposure to vapors released from subsurface soil/ground water to ambient air

Vapor concentrations were screened against Industrial Air Regional Screening Levels (RSLs) from USEPA. Presented in Technical Memorandum #6.

Site worker exposure to pond water Water concentrations were screened against Tap Water RSLs or MCLs from USEPA.

Site worker exposure to pond sediment No screening was conducted prior to site- specific risk calculation.

Utility worker exposure to vapors released from subsurface soil/ground water to trench air

No screening was conducted prior to site- specific risk calculation using Virginia Department of Environmental Quality (VDEQ) methodology.

Construction worker exposure to vapors released from subsurface soil/ground water to trench air

Screening was not conducted prior to site- specific risk calculation using VDEQ methodology.


8 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Scenario/Pathway Screening Method Construction worker exposure to pond water

Water concentrations were screened against Tap Water RSLs or MCLs from USEPA.

Construction worker exposure to pond sediment

Screening was not conducted prior to site- specific risk calculation.

Recreational exposure to surface water in Bull Creek

Water concentrations were screened against available Kansas Surface Water Quality Standards.

Recreational exposure to sediment in Bull Creek

Screening was not conducted prior to site- specific risk calculation.

Recreational exposure to soil at the former Pitch Pit

Soil concentrations were screened against Residential RSLs from USEPA.

The results of the screening evaluation, i.e., COPCs for the non-standard exposure pathways, are summarized in Appendices B-3 (surface water), B-4 (sediment) and B-5 (soil).

The supporting screening evaluations for worker exposure to water in the ponds in SWMUs 07, 08, and 09, and Bull Creek are provided in Appendices B-6 through B-9. The supporting screening evaluation for recreational exposure to soil at the former Pitch Pit is provided in Appendix B-10.

These screening evaluations were used to identify COPCs for the relevant non-standard exposure pathways. COPCs for the remaining non-standard exposure pathways were developed based on detection in at least one sample in the medium.

2.3 DATA QUALITY

Data quality evaluations were performed for the analytical data used in the Tier 3 HHRA. The evaluations were conducted following USEPA guidance in RAGS (USEPA, 1989), Guidance for Data Useability in Risk Assessment (USEPA, 1992), and other relevant guidance. The usability criteria identified in the cited 1992 guidance document were used in the evaluation of the suitability of data for use in quantitative risk estimation. Note that usability factors were also considered in the design of the proposed sampling and analysis, as recommended in the 1992 guidance (e.g., analytical methods/detection limits, representativeness goals, precision as indicated by QA/QC samples).

A detailed assessment provided in the RBSE examined the data and associated documentation to determine:

• Whether the minimum data requirements and performance objectives were met;

• If not met, what are the potential impacts to the risk assessment; and

• What actions, if any, are needed to satisfy the performance objectives.


9 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Six data usability criteria were evaluated with conclusions that the minimum data requirements and performance objectives were met:

• Reports to Risk Assessor - Were relevant data and documentation supplied to the risk assessor;

• Data Sources - Were broad spectrum analytical results available for at least one sample per medium per exposure pathway;

• Documentation - Were documentation (e.g., chain-of-custody records, standard operating procedures, field and analytical results) available to connect sample results to site locations;

• Analytical Methods and Detection Limits - Were routine analytical methods used to identify constituents in critical samples, and were detection limits in critical samples less than 20 percent of the relevant screening levels;

• Data Review - Was the correctness of analytical results reviewed; and

• Data Quality Indicators - Was sampling variability quantified for each constituent, and was analytical variability quantified through the use of field and laboratory quality control (QC) samples?

Approximately 1,000 samples have been collected across the site to support this effort. The majority of the site data (over 600 samples) were collected as part of the Comprehensive Investigation. Sample results and the associated data validation reports were provided in the Comprehensive Investigation Report, Document 5, dated October 13, 2005. An additional 84 samples were collected during expansion construction projects. This combined data set was included in the RBSE data quality evaluation described above. Following the RBSE, almost 300 supplemental samples were collected as part of the data gaps sampling event. Sample results and data validation reports for supplemental data were provided in Data Gap Sampling Event Summary Report, approved on October 18, 2013 by KDHE. Two laboratory reports were revised subsequent to the report approval and included SPLP results for naphthalene in three samples. A copy of the revised report is provided in Appendix K (compact disc (CD)).

The majority of data collected for the refinery were considered valid and usable for the Tier 3 HHRA. A minor subset of data was rejected as invalid and unusable due to data quality concerns. The rejected data and rationale for rejection are summarized below in general terms (full details were provided in the prior reports). The rejected data were excluded from the Tier 3 HHRA.

• Not Detected hexavalent chromium reanalysis results in seven samples (A0CO2/DG-SD16; A0CO2/DG-SD17; A0CO2/DG-SD18; A0CO2/DG-SD21; A0CO2/DG-SD23; A0CO2/DG-SD24; and A0CO2/DG-DUP-01) in laboratory report 60126767 were rejected due to exceedance of the 30-day holding time. Qualified hexavalent chromium results from the initial analysis of these samples were considered valid and usable for the risk assessment.


10 \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

• Not detected cyanide results in 18 samples (SMU09/DG-SDO3B; SMU09/DG-SDO4B; SMU25/DG-SB07; SMU31/DG-SB07; SMU31/DG-SB11; SMU31/DUP01; SMU33/DG-SD13B; SMU11/DG-SB10A; SMU11/DG-SB10B; SMU11/DG-SB10C; SMU11/DG-SB10D; SMU11/DB-SB10E; SMU09/DG-SD09; SMU09/DG-SD11; SMU-DG-SD12A; SMU09/DUPA; SMU09/DUPB; and SMU09/DG-SB10B) in laboratory reports 60127403, 60127625, 60127813, 60127817, and 60127847 were rejected due to exceedance of the 14-day holding time.

• Not detected PAH results in 13 samples (SMU09/DG-SDO3A; SMU09/DG-SDO4A; SMU09/DG-SD06; SMU09/DG-SD08; SMU09/DG-SD09; SMU09/DG-SD10A; SMU09/DG-SD11; SMU09/DG-SD12A; SMU09/DUPA; SMU08/DG-SD02; SMU08/DG-SD03; SMU08/DG-SD04; and SMU08/DG-SD05) in laboratory reports 60127847 and 60127964 were rejected due to surrogate recoveries less than 10%.

The exclusion of these data from the risk evaluation does not represent a significant deficiency in site characterization or risk characterization. Although the reanalysis for hexavalent chromium was rejected due to exceedance of holding time, the original hexavalent chromium analysis results were reviewed and deemed usable. Sample locations where cyanide was rejected were resampled with usable data. The rejected PAH results for SWMU 08 and SWMU 09 represent a small fraction of the full data set. The rejected PAH results were reported as Not Detected, therefore concentrations are likely low. There is a large and sufficient amount of quantitative information available for the critical constituents (those contributing most to site risk) identified in this assessment. The RFI characterization objectives have been met. Ample and appropriate data have been collected to adequately characterize site risks/hazards and provide corrective action recommendations, as necessary.

Consistent with the active nature of the facility, there have been structural and functional changes to the investigated areas since the execution of the initial Consent Order in December 2000. Site changes which affected environmental samples were incorporated into the risk assessment dataset used for the RBSE (2010). The RBSE dataset was augmented with valid analytical data from the data gap sampling to create the Tier 3 HHRA dataset. Site changes subsequent to the RBSE which may reduce potential risk/hazard will be evaluated and discussed as interim measures for soil in a separate forthcoming submittal.

For ease of reference, an up-to-date comprehensive summary of the analytical data used for quantitative analysis in the Tier 3 HHRA is provided on CD in Appendix L. Sample locations for the analytical data in each EA are shown on figures provided in Appendix C.

2.3.1 Total Petroleum Hydrocarbons

Select petroleum products (i.e., gasoline and diesel) were reported in different terminology due to differences in analytical methods over the timeframe in


11 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

which samples were collected to support the risk assessment. Methods OA-1 and OA-2 were used during the Comprehensive Investigation. Method 8015B was used during the data gap sampling. Gasoline was reported as gasoline range hydrocarbons using method OA-1 and TPH-GRO using method 8015B. For the risk assessment, gasoline range hydrocarbons and TPH-GRO were treated as a singular constituent and referred to as gasoline range hydrocarbons. Diesel was reported as diesel fuel using method OA-2 and TPH-DRO using 8015B. For the risk assessment, diesel fuel and TPH-DRO were treated as a singular constituent and referred to diesel fuel.

An issue related to data quality is the utility of data for results reported as "total petroleum hydrocarbons". In addition to reporting specific petroleum products (e.g., gasoline range hydrocarbons, diesel fuel, fuel oil, jet fuel, kerosene, mineral spirits, and motor oil) using Methods OA-1 and OA-2, the laboratory reported total petroleum hydrocarbons in a minor subset of samples. The reported value is typically qualified by the laboratory with an explanation indicating that the sample result does not match a profile of laboratory standards, but that light to heavy hydrocarbons fractions are present in the C14 to C30 plus range, and motor oil was therefore used as the quantitation standard. For data screening and quantitative risk evaluation, total petroleum hydrocarbons data were included for completeness, and the results were evaluated using the more conservative gasoline range hydrocarbon toxicity values consistent with the approach used in the approved RBSE. The uncertainty associated with using these data for risk evaluation, given the lack of a reasonable match to specific hydrocarbon material, is discussed in Section 5.5 and the Uncertainty Analysis.

EPA Method 8015, which was used to analyze the hydrocarbon mixtures in data gap soil samples at the Refinery, analyzes purgeable and extractable hydrocarbons with boiling point ranges roughly corresponding to gasoline, diesel fuel, etc. It is a non-compound-specific method susceptible to different responses for different compounds. Some hydrocarbons may be reported in both gasoline range hydrocarbons and diesel fuel range. Additionally the results include polar non-hydrocarbons and non-petroleum hydrocarbons with molecular weights within the range specified for the reported petroleum product (Lundegard and Sweeney, 2004). For purposes of quantitative risk assessment, there is a high degree of uncertainty associated with assigning toxicity factors to the Method 8015 mixture results. The highest degree of uncertainty for the Refinery data set is associated with the result termed total petroleum hydrocarbons.

The uncertainty in defining toxicity stems from the fact that numerous individual chemicals comprise the hydrocarbon mixtures detected. Each sample defined as containing diesel range hydrocarbons, for example, differs in composition due to variability in composition in crude oil, intermediates, refined products, and environmental weathering of the material. The standard risk assessment methodology includes assigning a toxicity value considered to be conservative to represent potential risk for the mixture. In general, this allows for quantitative evaluation that supports identification of the concentrations and site locations


12 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

that are not likely associated with significant risk, and those which may pose a risk and therefore warrant either corrective action or further, detailed chemical characterization to support additional risk analysis.

Current research and practices on TPH risk evaluation have moved to include the use of hydrocarbon fraction analyses to provide a more detailed breakdown of the mixture and support refined identification of both physical properties and potential toxicity of the components (USEPA, 2009). Analytical fractions quantified through these methods are defined based on an expectation of similar physical, chemical, and transport properties (e.g., sorption, solubility, and vapor pressure) as well as reasonably similar toxicological properties. Guidance has been developed by a number of organizations, [e.g., KDHE, Texas Commission on Environmental Quality (TCEQ), Massachusetts Department of Environmental Protection (MADEP), Agency for Toxic Substances Disease Registry (ATSDR), TPH Criteria Working Group], all based on similar principles, but differing slightly in the specific breakdown of fractions (e.g., number and carbon ranges). In all cases, toxicity has been addressed by using a surrogate approach in which one or more "toxic" compounds represent the fraction. The health effects of lighter fractions are better characterized than heavier fractions, as more is known about the representative compounds.

To provide additional information on petroleum hydrocarbons detected at the Refinery, thirteen samples were collected in locations with elevated petroleum hydrocarbon mixture data and analyzed for petroleum hydrocarbon fractions, i.e., aliphatic and aromatic equivalent carbon chains using the Texas Methods 1005 and 1006. 1 Texas Method 1005 reports results as C6 to C12; >C12 to C28; and >C28 to C35. Texas Method 1006 further speciates the carbon chains into the following aliphatic and aromatic fractions:

• Aliphatic C6 • Aliphatic >C6-C8 • Aliphatic >C8-C10 • Aliphatic >C10-C12 • Aliphatic >C12-C16 • Aliphatic >C16-C21 • Aliphatic >C21-C35

• Aromatic >C7-C8 • Aromatic >C8-C10 • Aromatic >C10-C12 • Aromatic >C12-C16 • Aromatic >C16-C21 • Aromatic >C21-C35

A qualitative assessment of the TPH fraction data is discussed in the risk characterization section of this report, and provides insight into the limitations of risk evaluation of the Method 8015 mixture results. This analysis is important to the Refinery risk assessment because the hydrocarbon mixtures are identified as COPCs exceeding target non-carcinogenic hazard range in certain areas of the Refinery.

1 The Texas 1006 method has been the default method used in Texas for in-depth characterization of TPH for 15 years. It is widely used in other states as well.

2.3.2 Soil Vapor Data

The soil vapor sampling completed at the site during the Data Gaps effort used a shroud over the sample collection system, filled with helium. Detections of helium at greater than 10% of the concentration in the sampling shroud occurred in three soil vapor samples collected in March 2013 and indicate that the sampling system was not capturing solely soil vapor. The introduction of ambient air into the samples would potentially result in lower reported concentrations. The analytical results reported for the following samples are potentially biased low as a result of these leaks: DG-SGO3 10; DG-SGO7 5; and DG-SG12 6. The data were not rejected, but the potential bias (particularly potential low bias) is noted for complete information.

The impact of the uncertainty associated with samples DG-SGO3 10, DG-SGO7 5, and DG-SG12 6 is low given that they did not represent the maximum vapor concentration locations, which were used to conservatively quantify risks associated with soil vapor pathways.

3.0 EXPOSURE ASSESSMENT

The objective of the exposure assessment is to estimate the nature, type, and magnitude of exposures to COPCs present in media of concern. The exposure assessment identifies potential receptors and exposure pathways. Exposure scenarios, with associated intake assumptions, are identified for pathways considered complete. The level of constituent intake is then estimated for those pathways considered complete.

An exposure assessment was performed using the available information. A conceptual site model (CSM) for human health receptors was developed for the Tier 3 HHRA (Figure 3-1). The CSM identified the exposure pathways that were potentially complete for the Refinery and evaluated in the Tier 3 HHRA. In accordance with agency-approved plans, the receptor exposure scenarios that were quantitatively evaluated in the Tier 3 HHRA are summarized in Table 1 (RAGS Part D format), and discussed below.

Exposure pathways that were not quantified as part of the Tier 3 HHRA are discussed in an uncertainty analysis. These pathways include those that were eliminated based on comparison with conservative screening values, or where the potential carcinogenic risk and non-carcinogenic hazard can be conservatively estimated using other quantified exposure scenarios.

3.1 RECEPTOR EXPOSURE SCENARIOS

The following sections describe the exposure scenarios for human receptors and potentially complete exposure pathways and routes. Exposure assumptions for each scenario are identified in Tables 4.1 through 4.16.

3.1.1 Soil Receptor Scenarios

Site Worker Scenario: A site worker is assumed to be an adult industrial worker involved in day-to-day routine worker activities within the Refinery boundaries. Access to the Refinery is controlled by fencing and significant security measures. The site worker is assumed to have routine direct contact with surface soil at previously defined EAs, within a depth interval from 0 to 1 foot below ground surface (bgs), via incidental ingestion and dermal contact. It is assumed that volatile constituents and affected dust/particulates may be released from these surface soils and/or waste to ambient air and may be inhaled by this receptor. A significant portion of the Refinery and the SWMUs/A0Cs include surface cover such as gravel or pavement (concrete or asphalt). For purposes of the risk assessment, the presence of surface cover was not considered to eliminate or reduce direct contact exposure, which is a highly conservative evaluation of potential risk under current conditions for the covered areas. The exposure assumptions for the site worker are provided on Table 4.1.

Utility Worker Scenario: Utility-related activities may take place at the Refinery and potentially result in worker exposure to constituents in surface and


15 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

subsurface soils in the 0 to 5 feet bgs interval. It is the experience of CHS that exposure in this type of scenario has been (and will be) short-term (e.g., weeks) due to the nature of the activities associated with this type of work. The utility worker is assumed to have direct contact with surface and subsurface soils/waste through incidental ingestion, dermal contact, and inhalation of volatiles and dust particles. CHS health and safety policies require appropriate worker protection during excavation work to reduce potential exposure. However, for purposes of the risk evaluation, these measures were not considered to eliminate or reduce direct contact exposure. In the absence of specific plans for utility installation/repair, a utility worker is assumed to be exposed within EAs as previously defined. The exposure assumptions for the utility worker are provided on Table 4.2.

Construction Worker Scenario: Construction activities, including excavation, may occur at the Refinery and result in exposure to COPCs in surface and subsurface soils in the 0 to 10 feet bgs interval. It is the experience of CHS that exposure in this type of scenario is also of limited duration, although potentially longer than the short term utility-type work. Examples of construction activities include expansion or capital projects, such as the Heavy Crude Expansion Project (which involved various tanks and the Benzene Reduction Unit), Clean Fuels Project (which involved the Hydrogen Unit and Unicracker), recent wastewater treatment plant upgrades (new wastewater treatment plant), and oily-water sewer replacement in several units. The excavation activities are subject to CHS worker protection policies, although no worker protection measures were assumed for the risk assessment. The construction worker is assumed to have direct contact with surface and subsurface soils/waste through incidental ingestion, dermal contact, and inhalation of volatiles and dust particles. The construction worker is also assumed to be exposed within EAs as previously defined. The exposure assumptions for the construction worker are provided on Table 4.3.

Recreational Scenario: Under current and future conditions, an older child (e.g., 10 to 18 years) could periodically enter SWMU 33 (former Pitch Pit), which is located north of Bull Creek outside the fence line of the Refinery. Exposure to surface soils (0 to 1 foot bgs) was assumed to occur at SWMU 33. The asphalt- like waste material historically present on the surface at SWMU 33 was excavated in September 2009 under Special Waste Disposal Authorization No. 09-0630, and disposed off-site at the Reno County Landfill Soil exposed by the removal action has been sampled and a recreational receptor is assumed to have direct contact with the surface soils through incidental ingestion, dermal contact, and inhalation of volatiles and particulates. The exposure assumptions for the recreational receptor are provided on Table 4.4.

Discussion of site-specific exposure assumptions for the soil receptor scenarios is provided in Section 4.2.

3.1.2 Soil Vapor Scenarios

While there is overlap with the receptor scenarios identified for soil in the prior section of this report, the receptor scenarios to be evaluated for soil vapor are discussed separately in order to clearly identify how the vapor data were utilized in the Tier 3 HERA. Soil vapor sample data are considered reflective of contributions from both soil and ground water sources including light nonaqueous phase liquid at the ground water interface, as applicable, and use of the vapor data provided a means to characterize risk associated with all source media. Because apparent ground water impacts are present in several portions of the facility, and because commingled ground water plumes are likely to exist from more than one historical source, risk estimates for the outdoor air pathways may not be directly attributed to a SWMU or AOC.

Soil vapor samples were also collected in the eastern portion of the facility, outside of the processing area, not located within any identified SWMUs or AOCs in the CAFO. This area contains office buildings, shop and warehouse buildings, and the refinery fire department building, and is referred to as the "Eastern Area" in the risk assessment. Soil vapor sampling was performed in this area due to the presence of ground water impacts and to provide characterization in an area where buildings and workers are present.

Site Worker Scenario: In addition to the surface soil exposures identified in Section 3.2.1.1, the outdoor site worker is assumed to be exposed to vapors released from the subsurface to outdoor air via inhalation. For the outdoor site worker, the presence of pavement and Refinery health and safety policies, which may eliminate or reduce inhalation exposure, have not been incorporated into the quantitative risk assessment. The exposure assumptions for the inhalation pathways for the site worker are provided on Table 4.5 for outdoor air. Note that the outdoor air inhalation pathway is evaluated in two ways for this receptor, through the standard algorithm of soil-to-air volatilization factor and also using a separate soil vapor to ambient air calculation in EAs where soil vapor data were available.

A separate receptor, the indoor site worker, is assumed to be exposed to vapors released from the subsurface to indoor air. As noted previously, a portion of the Refinery and the SWMUs/ADCs have pavement (concrete or asphalt) as surface cover. Some existing structures, such as control rooms, have engineering features which limit vapor intrusion as specified in 19 Code of Federal Regulations 1910.119 (Process Safety Management of Highly Hazardous Chemicals) and American Petroleum Institute Standards 752 (Management of Hazards Associated With Location of Process Plant Buildings) and 753 (Management of Hazards Associated With Location of Process Plant Portable Buildings). As discussed with KDHE, the engineering features will be considered in the selection of buildings for detailed evaluation of the indoor worker. Exposure assumptions for the indoor site worker will be provided in a forthcoming addendum to the Tier 3 FIFIRA.


17 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

An Indoor Worker may, hypothetically, have duties comprised of part indoor and part outdoor work (either over the course of a working day or working career at the Refinery). Based on information provided by CHS, of the scenarios evaluated in the human health risk assessment [Site Worker, Utility Worker, Construction Worker, and Recreational Receptor (e.g., adolescent)], the Site Worker scenario is the most likely scenario to be relevant to a portion of the Indoor Worker's duties. Potential risk/hazard for a Site Worker assumed to spend part of their work time in both indoor and outdoor areas is further discussed in a forthcoming addendum to the Tier 3 HHRA Report.

Utility and Construction Worker Scenarios: In addition to the soil exposures identified in Section 3.1.1, utility and construction workers are assumed to be exposed to vapors released from the subsurface to surface outdoor air and outdoor trench air via inhalation. For purposes of the risk assessment, CHS health and safety policies which require appropriate worker protection (e.g., for vapor inhalation) during excavation work were not considered to eliminate or reduce potential exposure. Refinery health and safety policies for intrusive work where impacted environmental media are encountered include Refinery-specific Safety Orientation, HAZWOPER training, and Occupational Health and Safety Administration (OSHA)-compliant standard operating procedures (SOPs) including, but not limited to, personal protective equipment, air monitoring, and excavation. The excavation SOP includes an excavation permit reviewed by CHS McPherson safety personnel. Site management-related procedures and programs relevant to intrusive activities at locations where impacted environmental media are encountered are summarized below.

Procedures/ Programs Department Description Procedure 6644 - Safety Procedure 6644 specifies rules that must be followed Excavations by personnel conducting or overseeing excavations

before and during excavation work conducted at the Refinery. Procedure 6644 was developed consistent with 29 CFR 1926 Subpart P "Excavations" which provides rules for excavations and safe work practices for construction workers involved in trenching. Procedure 6644 also presents requirements for atmospheric testing for excavations four or more feet in depth.

6646 - Respiratory Safety Respiratory Protection Program 6646 sets Protection requirements for personnel to follow regarding the Program proper use and care of various types of respirators as

provided in 29 CFR 1910.134. Fit testing, medical evaluations, and training requirements are also covered in Respiratory Protection Program 6646. A respirator selection table is provided showing respiratory hazards, type of respirator to use for the associated hazard, filter/cartridge types and recommended respirator use.


18 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Procedures/ Programs Department Description Procedure 6647 - Personal Protective Equipment

Safety Procedure 6647 provides for the selection and proper use of personal protective equipment (PPE) as specified in 29 CFR 1910.132 through 138. Health and safety protection Levels (A, B, C, and D) are provided in the procedure. A Hazard Assessment/PPE Selection Chart is also provided showing job classifications, common hazards and required PPE associated with those job classifications.

Procedure 6652 - Confined Space Entry Procedure

Safety Procedure 6652 presents procedures to protect personnel from hazards associated with activities conducted within confined spaces. Procedure 6652 was developed consistent with 29 CFR 1910.146 "Permit-Required Confined Spaces"; 1910.1000 "Air Contaminants"; 1910.1200 "Hazard Communications"; and ANSI/ASSE Z117.1-2003. Training requirements, confined space preparation, confined space entry, personnel responsibilities, permits, atmospheric testing, PPE, and other associated hazards are covered in Procedure 6652.

Procedure 7248 - Dirt and Debris Excavation Requirements

Environmental Procedure 7248 provides environmental guidance for soil disturbing activities conducted at the Refinery. Procedure 7248 includes a digging notification checklist that must be completed and submitted to the Environmental Department for review and approval prior to conducting dirt disturbing activities. Under Procedure 7248, the Environmental Department will evaluate the excavation area for environmental impacts prior to digging. Additional health and safety measures may be implemented based on the evaluation performed. A dirt and debris tracking form is also included as part of Procedure 7248 to track soil that is removed from the excavation site.

Notes: CFR - Code of Federal Regulation ANSI - American National Standards Institute ASSE - American Society of Safety Engineers

Results of the Comprehensive Investigation and Tier 3 HHRA are utilized by the Environmental and Safety Departments at CHS to assist in determining appropriate worker protection during intrusive activity. Health and safety procedures and programs are reviewed periodically (typically annually, or earlier if warranted) for applicability and improvement.

As requested by KDHE, CHS relied on guidance from the VDEQ to evaluate inhalation of outdoor trench air during trenching/excavation activities. The VDEQ model and default values were utilized to the extent possible, with an adjustment made to reflect measured soil vapor concentrations as the 'starting point' in lieu of ground water concentrations. The exposure assumptions for the inhalation pathway for the utility and construction workers are provided on


19 \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Tables 4.6 and 4.7 for surface outdoor air, and Tables 4.8 and 4.9 for trench air. As noted for the site worker, the inhalation pathway is evaluated in two ways for this receptor, through the standard algorithm of soil-to-air volatilization factor and also using a separate soil vapor to trench air calculation in EAs where soil vapor data were available.

Discussion of site-specific exposure assumptions for the outdoor air scenarios is provided below in Section 4.2.

3.1.3 Surface Water and Sediment Receptor Scenarios

The surface water and sediment receptor scenarios pertain to surface water bodies located within or near the Refinery, i.e., Bull Creek (AOC 02), the Equalization Basin (SWMU 07), the Aeration Pond (SWMU 08), and the 10-Acre Effluent Lagoon (SWMU 09). In the Region 4 Human Health Risk Assessment Supplemental Guidance (USEPA, 2014) it is stated that "In most cases it is unnecessary to evaluate human exposures to sediments that are always covered by surface water." Based on experience at this facility, CHS believes that the potential for sediment exposure within surface water features at the site is very limited and unlikely to contribute significant risk for human receptors. However, CHS is complying with the expressed request of KDHE and USEPA to evaluate sediment exposure, however limited. Incidental exposure was evaluated in accordance with final USEPA guidance, where available (e.g., dermal exposure was evaluated in accordance with the RAGS Part E (USEPA, 2004)).

Site Worker Scenario: A site worker may have incidental contact with surface water (via ingestion, dermal contact, and inhalation of vapors) and sediment (via ingestion, dermal contact, and inhalation of vapors) in on-site ponds associated with infrequent and/or limited duration events within the ponds such as for aerator maintenance (SWMU 08 and SWMU 09), and via use of pond water as utility water. Utility water uses include firefighting training (SWMU 09), activation of the sprinkler system during a fire alarm (SWMU 09), unit washing (SWMU 09), and filter press slab washing (SWMU 09). The pond served as a historical source of water for the above listed utility tasks. Currently, utility tasks are performed using city effluent water, with the pond serving as a backup water source. The assumptions for exposure to surface water and sediment for the site worker are provided on Tables 4.10 and 4.13, respectively.

Construction Worker Scenario: A construction worker may have incidental contact (via ingestion, dermal contact, and inhalation) with surface water and sediment in the on-site ponds should these ponds ever need to be dewatered in the future. This is a hypothetical scenario as it has not occurred in CHS history. This type of activity would only be relevant if additional storage capacity was needed from the ponds and construction/clean out required dewatering. CHS does not foresee closure of these ponds while the Refinery is operational. Dewatering is not anticipated for the foreseeable future, particularly for SWMU 09 which serves as a water reservoir for fire-suppression activity. A quantitative evaluation was


performed in the Tier 3 HHRA for this scenario for SWMUs 07, 08, and 09. The assumptions for exposure to surface water and sediment by the construction worker are provided on Tables 4.11 and 4.14, respectively.

Recreational Scenario: A recreational receptor that visits Bull Creek at the Refinery or downstream of the Refinery is assumed to have incidental contact with surface water (ingestion, dermal contact and inhalation of vapors) and sediment (ingestion and dermal contact) in Bull Creek. Inhalation of vapors from submerged sediment was considered an incomplete pathway for this receptor. The surface water in Bull Creek is generally at least several feet deep; therefore, dermal contact with submerged sediment is likely to be infrequent. The assumptions for exposure to surface water and sediment for the recreational receptor are provided on Tables 4.12 and 4.15, respectively.

The recreational receptor may also potentially be exposed to COPCs in surface water via ingestion of fish caught from Bull Creek. Exposure assumptions for the fish ingestion scenario are provided on Table 4.16.

Access to on-site ponds (SWMUs 07, 08, and 09) is not a reasonably likely scenario for a recreational receptor given the access controls and security measures in place at the Refinery. Nonetheless, potential risk to this receptor can be estimated (i.e., would be conservatively represented) by the risk to workers from occasional exposure to SWMUs 07, 08 and 09. As approved by KDHE in a letter dated February 22, 2012, a qualitative assessment of potential exposure to on-site ponds for the recreational receptor scenario is provided in the uncertainty analysis. The potential risk for this scenario will be re-evaluated should future site use change such that current access restrictions are eliminated and ponds become accessible to the general public.

Discussion of site-specific exposure assumptions for the surface water and sediment scenarios is provided below in Section 4.2.

3.2 INTAKE EXPOSURE ASSUMPTIONS

In order to quantify exposure, various parameters are integrated to express the intake that occurs over time. The intake is expressed as a function of the body weight of an individual. Each intake variable has a range of possible values for a given exposure pathway. Intake values have been selected for the Tier 3 HHRA to provide an estimate of the reasonable maximum exposure (RME) for a receptor. The RME is the highest exposure that is reasonably anticipated to occur at a site and is intended to estimate a conservative exposure scenario that is within the range of possible exposures.

The exposure assumptions utilize standard values recommended by USEPA as well as values based on USEPA reference data sources (e.g., Child-Specific Exposure Factors Handbook). Site-specific exposure input parameters were assumed, where appropriate, and are discussed below. The exposure input


21 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

parameter values are identified in Tables 4.1 through 4.17 by exposure scenario, and the reference source or rationale for each value is provided in the tables. In order to clearly identify the basis for site-specific exposure factors, the following subsections provide additional description of site-specific values. Default and site-specific values used to calculate daily intake were provided in the Tier 3 Risk Assessment Work Plan approved by KDHE in a letter dated February 22, 2012. No deviations from the approved values were made in developing the quantitative assessment.

3.2.1 Site Worker Scenario

For surface water (Table 4.10) and sediment (Table 4.13), an exposure frequency (EF) of 175 days per year was assumed for the site worker based on the timeframe typically taken to complete activities that may result in pond water contact at the refinery. In the experience of CHS, direct contact with water inside the pond is limited to pond maintenance activities, which are performed infrequently. The aerator in SWMU 08 is scheduled for preventative maintenance once every six months, for an estimated one hour per event. The aerators in SMWU 09 are serviced on an as-needed basis. CHS estimates that motor replacements for the aerators in SWMU 09 occur once every three years and take approximately four hours to perform the task. When considering contact with pond water in a broader scope, more frequent exposure was identified through transporting of the pond water to other areas of the Refinery for historic use as on-site utility water. Activities associated with utility water include fire training, unit washing, and filter press slab washing. As mentioned in Section 3.1.3, utility tasks are currently performed using city effluent water, with the pond serving as a backup water source. For the purposes of this risk assessment, exposure to pond water during utility tasks are assumed. Of these activities, the greatest potential exposure to utility water is from washing the filter press slab via water siphoned from a fire hydrant. Based on the experience of CHS, filter press slab washing takes place daily for five minutes per day, five days per week, for eight months (35 weeks) per year. The RME EF of 175 days (5 days/week x 35 weeks/year) was assumed based on this scenario. Exposure to utility water for lesser activities, based on observations by CHS personnel, is estimated to be one hour every two months (fire training), and 30 minutes per week for six months per year (unit washing). Units with concrete ground surface are washed more often, whereas units with gravel surface are washed infrequently. For dermal contact with surface water and sediment (entrained in utility water), an exposure time of 5 minutes per day was assumed. A skin surface area of 1,306 cm2, including face and hands, is likely based on the following site conditions. This surface area was considered likely because full immersion in the ponds has not historically occurred and is not reasonably expected to occur during activities such as pond maintenance and utility water usage. Historically, site workers have used a boat to access equipment in the pond, such as aerators, for maintenance, thereby limiting dermal contact with surface water and sediment. Additionally, attire typically worn by outdoor workers in the Refinery would also limit dermal contact. In the case of fire training, dermal contact would be even more limited due to the use of bunker


gear (or turnout gear), which is the heavy outer clothing worn by firefighters. However, as a conservative measure, the default skin surface area of 3,300 cm 2

recommended by KDHE was assumed.

Based on the lack of default values for sediment contact exposure by adult receptors, parameters including ingestion rate and adherence factor were based on USEPA recommended default soil values. As requested by KDHE, the sediment daily ingestion rate was not adjusted to reflect a 5-minute daily exposure; rather, the KDHE-recommended value of 50 mg/day was assumed for the sediment daily ingestion rate. This highly conservative value is equivalent to one-half the default soil ingestion rate for an outdoor worker. For the inhalation pathway, an event (exposure) time of 0.083 hours per day (five minutes per day) was assumed based on site-specific knowledge of potential site worker exposure. It is acknowledged that this exposure time is very short and likely not meaningful for exposure estimation, but is included based on best site-specific information.

3.2.2 Utility Worker Scenario

On Tables 4.2, 4.6, and 4.8, an EF of 130 days was assumed based on the higher end timeframe typically taken to complete utility-type shallow excavation activities at the refinery. In the experience of CHS, such activities, completed in the 0 to 5 foot depth have included conduit installation, utility installation or repair, water line repair, and sewer repair. The lines are typically three feet bgs. These activities are generally conducted by contract employees, and durations have typically ranged from one week to six months in a given year. The RME EF of 130 days was assumed based on work performed five days a week for six months. It is possible that the same contractor may perform such activity for multiple years. An exposure duration (ED) of 6 years (Tables 3-2 and 3-6) was assumed as the RME. This value is based on an adjustment made to the median occupational tenure of 3.6 years for a construction worker provided in the Exposure Factors Handbook (USEPA, 1997). The upper range for occupational tenure was not provided in the Exposure Factors Handbook (USEPA, 1997); therefore to account for potentially higher durations due to reduced mobility in the area, the median value of 3.6 yrs was multiplied by a factor of 1.5 (or +50%) and rounded to the next integer. The more recent Exposure Factors Handbook: 2011 Edition (USEPA, 2011, Table 16-106) does not provide occupational tenure data specific to utility or construction workers. However, the median occupational tenure of 5.5 years for "operators, fabricators, and laborers" was consistent with the exposure duration of 6 years assumed for the utility worker. For the dermal exposure pathway (Table 4.2), a default skin surface area of 3,300 cm2 recommended by KDHE was assumed in lieu of a site-specific value of 1,306 cm2 for the face and hands based on attire typically worn by outdoor workers in the Refinery. For the trench air inhalation pathway, the VDEQ default values for trench dimensions of 3 feet by 18 feet were assumed.


23 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

3.2.3 Construction Worker Scenario

For the soil exposure and outdoor air pathways (Tables 4.3, 4.7, and 4.9), an EF of 130 days (i.e., 5 days per week for 26 weeks or 6 months) and ED of 1 year was assumed based on the timeframe typically taken to complete excavation associated with major construction activities at the Refinery. Construction projects that result in excavation to depths of 10 feet bgs typically are large projects that involve multiple phases, and it is the experience of CHS that the construction worker involved in earth work is not likely to be involved in all phases of the project. The earth-moving phases of construction projects, during which exposure to subsurface soil may occur, have ranged from one to six months in the experience of CHS. For the trench air inhalation pathway, trench dimensions of 75 feet by 100 feet were assumed as reasonable and conservative based on recent construction projects at the Refinery and potential future construction projects.

In agreement with the February 22, 2012 letter from KDHE and the March 21, 2012 electronic mail communication with TechLaw, Inc., CHS quantitatively assessed construction worker exposure to on-site pond water and sediment. Assuming construction workers may be involved in hypothetical dewatering and cleanout of ponds, EFs were determined for each of the ponds (SWMUs 07, 08, and 09) for surface water and sediment pathways considering the scope for each pond. EFs of 1, 3, and 5 days for surface water exposure and EFs of 1, 6, and 86 days for sediment exposure were calculated for SWMUs 07, 08, and 09, respectively, largely based on size of the project. Refer to Table 4.11 and Table 4.14 for a detailed breakdown of the EF calculations for each unit and site- specific values for other parameters. An ED of 1 year was assumed for this hypothetical scenario based on the time estimated to complete the activity. For dermal contact with surface water and sediment, a default skin surface area of 3,300 cm2 recommended by KDHE was assumed in lieu of a site-specific value of 1,306 cm2 for the face and hands based on attire typically worn by outdoor workers in the Refinery. For the inhalation component of the surface water and sediment pathways for the construction worker, an event (exposure) time of eight hours was assumed based on a construction worker having a continuous eight-hour work day. Similar to the site worker, for pond sediment exposure during pond dewatering/ material removal by the adult construction worker, parameters including ingestion rate and adherence factor were assigned USEPA recommended default soil values.

KDHE requested that CHS include in this report a discussion of the potential disposal options for materials from a hypothetical pond cleanout activity. In general, based on Refinery waste management practices, disposal options would likely consist of off-site treatment and disposal via landfarming or landfilling consistent with the waste characteristics profile. Disposal by any of these options would result in no further exposure for CHS workers (or any potential receptors) at the Refinery following the removal activities. Should pond cleanout becomes necessary in the future, CHS will thoroughly evaluate management and/or


24 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

disposal options for the materials in keeping with current environmental standards and practices, and will notify KDHE of the final proposed method for addressing the materials.

3.2.4 Recreational Scenario

EA 2 (Bull Creek)

Based on observations by CHS, recreational use of the segment of Bull Creek within the Refinery property boundary by recreational receptors is unlikely. Recreational use, and evidence of recreational use, have not been observed in this creek segment. There is no path to traverse down to the creek. Trash debris, an indicator of human presence, also has not been observed along this segment of the creek.

For the hypothetical scenario of a recreational receptor visiting Bull Creek (which is located on Refinery-owned property), site-specific values were developed and presented in Tables 4.12 and 4.15. An EF of 26 days was assumed based on visitation to and active contact with media in Bull Creek twice a week, likely on weekends, during the summer months of June through August, when average air temperatures are above 70 degrees Fahrenheit. The average air temperature was used as an indicator for the water temperature. Contact with surface water and submerged sediment during additional months is not reasonably likely due to discomfort associated with colder water temperatures.

Exposure times of 0.58 hour (per 24 hour day or event) and 0.60 hour (per 24 hour day or event) were identified for the child and adult receptors, respectively. The Highlights of the Child-Specific Exposure Factors Handbook (USEPA 2009) indicates that youth ages 11 to <16 years spend an average of 139 minutes per month [or 17 minutes (0.29 hours) per event for 8 events] swimming, and young adults ages 18 to <21 years spend an average of 145 minutes per month [or 18 minutes (0.30 hours) per event for 8 events] swimming. To account for the potential for additional activities such as wading or fishing that do not necessarily include immersion in the surface water, the swimming times were doubled to recognize uncertainty and estimate a RME value.

For the child recreational receptor, an ED of 8 years was used (ages 10 to 18 years). For the adult recreational receptor, an ED of 7 years was used based on the assumption that total ED for a recreational receptor is 15 years (ages 10 to <25 years).

Body part-specific values for child adherence factors for dermal exposure to sediment were available. A weighted average was developed assuming values from children playing in sediment. The sediment ingestion rate (child and adult) and adherence factor for the adult were assigned USEPA recommended default soil values. Specifically, the sediment ingestion rates of 50 mg/day for adults and 100 mg/day for child were assumed in accordance with the KDHE letter dated November 1, 2011.


25 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Surface water ingestion rate, skin surface area, and body weight were based on mean data from the Highlights of the Child-Specific Exposure Factors Handbook (USEPA, 2009). For the skin surface area, the total body was assumed to be exposed to surface water while the hands, forearms, lower legs, and feet were assumed to be exposed to sediment. A weighted average body weight was developed for ages 10 to 18 years. The value for ages 18 to <21 years was assumed for adults 18 to <25 years.

For the fish ingestion scenario (Table 4.16), values for parameters such as the fish intake, percent lipids in whole and edible fish, and receptor body weight are based on USEPA recommended default values (USEPA, 1989, 2000, and 2002). A single constituent in AOC 2 warranted further evaluation for this pathway, and the bioconcentration factor (BCF) was presented in the Tier 3 Risk Assessment Technical Memorandum #2, and approved by KDHE in a letter dated April 4, 2013. The BCF and its source [for dibenz(a,h)anthracene] are also identified in Table 4.16.

EA 17 (SVVMU 33, Former Pitch Pit)

For the child recreational receptor scenario for EA 17 (Table 4.4), visitation by an older child (given location on Refinery-owned property) was assumed. There are currently no specific features that are attractive for recreation; however, it is assumed that an older child may access EA 17 twice a week (EF), likely on weekends, during more temperate months (May through October) with maximum temperatures above 70 degrees Fahrenheit. The ED for a child (8 years) was assumed based on regular and continued visitation by a child 10 to 18 years old.

Prior to the removal of the tar waste material, bike paths were observed in the area. However, signs that would indicate a human presence such as trash and disturbance of items in the area were only noted during periods of warm temperatures.

An exposure time of 2 hours per day was assumed based on data for active "doers" ages 11 to 15 years (USEPA, 2008). A soil ingestion rate of 100 mg/day was assumed (USEPA, 1993).

3.2.5 Soil Lead Exposure

Lead exposure associated with site soil (and sediment) is estimated in a different manner than other COPCs. Lead exposure is quantified in terms of blood lead concentration (micrograms of lead per deciliter of blood, ug/dL), which takes into account a baseline blood lead concentration as well as the incremental increase in blood lead concentration from exposure to site soil (and sediment). The USEPA's Adult Lead Model integrates information relating to environmental concentration, ingestion rate, absorption, and a proportionality constant to estimate an incremental blood lead concentration in the site receptor.


26 \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

The model also recommends the use of central tendency values instead of reasonable maximum values for parameter inputs. The Tier 3 Risk Assessment Work Plan identified the use of the USEPA's Adult Lead Model, but did not provide the model parameter values in detail. Therefore, the equation and assumptions are provided in detail herein. The equation used for estimating blood lead concentration in the (maternal) site receptor is (USEPA, 2003):

PbS x BKSF x IRx A F x EP' PbBmat.i (ug/dL). PbBb.line

where:

PbBbaseline = baseline blood lead level (ug/dL), USEPA default of 1.5 ug/dL from analysis of NHANES III (Phases 1 & 2);

PbS = soil lead concentration (ug/g), site-specific; BKSF = biokinetic slope factor (ug/dL per ug/day), USEPA default of 0.4; IR = soil ingestion rate (g/day), USEPA recommended value of 0.05

g/day for non-intensive contact (e.g., site worker and recreational receptor) and 0.1 for intensive contact (e.g., utility worker and construction worker);

AF = absorption fraction (unitless), USEPA default of 0.12; EF = exposure frequency (days/year), site-specific; and AT = averaging time (days/year), site-specific.

A 95 percentile fetal blood lead level is then predicted from the maternal blood lead level assuming the maternal PbB as a geometric mean and applying a ratio and empirical population-based geometric standard deviation.

PbBfetal (ug/dL) = PbBmatemal X Rfetal/maternal X GSD 1.645

where:

PbBfew = fetal blood lead level (ug/dL); PbBmaternal = maternal blood lead level (ug/dL); Rfetal/maternal = fetal/maternal blood lead ratio (unitless), USEPA default of

0.9; and GSD1645 = 95 percentile geometric standard deviation, USEPA default

of 2.1 from analysis of NHANES III (Phases 1 & 2).

USEPA default values, including blood lead, were provided in the Adult Lead Model spreadsheet dated June 21, 2009 from USEPA. Population blood lead data used in the model were from the USEPA 2002 update on lead values.

Because the recreational receptor at EA 2 (AOC 02 Bull Creek) is an adolescent, and there is greater uncertainty in use of the model for this age group, a sensitivity analysis was performed consistent with the guidance indicated in the USEPA's Frequent Questions for Risk Assessors on the Adult Lead Methodology (ALM) dated November 25, 2013. The additional evaluation assumed a more

AT

27 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx Environmental Resources Management

conservative Rfetal/maternal value of 1.0 and absorption fraction of 0.3. Results of the sensitivity analysis are discussed in the risk characterization (Section 5.2.4).

3.3 EXPOSURE POINT CONCENTRATIONS

Exposure point concentrations (EPCs) were determined for each COPC in the relevant media, for each of the 19 EAs. Samples collected to characterize and/or delineate the SWMUs and AOCs comprising the EAs were included in the data sets for calculation of EPCs at each EA. USEPA guidance (USEPA, 1992, USEPA 2002, Pro UCL support manuals) on the calculation of EPCs and other relevant literature were used to determine a method that is applicable and appropriate to the data distribution for estimation of EPCs. EPCs for soil, sediment, and surface water were selected as follows:

• For constituents with at least six data points, the 95% Upper Confidence Limits (UCLs) on the mean were calculated using the most recent public version of the ProUCL software available at the time of calculation (Version 5.0.00).

• For a limited subset of data with at least six samples, a valid 95% UCL on the mean could not be calculated due to a detectable concentration in only one sample. In these instances, the lower of the detected concentration and median concentration was selected as the EPC. For a median equal to a nondetect result, the full reporting limit was assumed. This selection of EPC was not addressed in the Tier 3 Risk Assessment Work Plan, and was identified following detailed review of the data distributions.

• For constituents with less than six data points, the maximum detected concentration was selected as the EPC.

• Lead EPCs were based on average concentrations.

EPCs for the evaluation of the fish ingestion pathway were estimated from 95% UCLs on the mean for surface water data collected in Bull Creek as part of the Data Gaps Sampling Program.

ProUCL outputs for 95% UCLs on the mean are provided in Appendix M. Summary statistics and EPCs are summarized on Table 3.1 through 3.14 for the various receptors and scenarios.

3.3.1 Soil Vapor Samples and EPCs

Soil vapor data are available for a subset of EAs, specifically EAs 3, 8, 9, 10, 11, 13, 18, and 19, and the Eastern Area. Therefore, the air inhalation pathway was evaluated for these EAs using soil vapor data in addition to soil data. For evaluation of trench air and outdoor air above ground surface for the utility worker and construction worker, using soil vapor data as a starting point for estimating breathing zone concentrations, the EPCs were based on concentrations from the soil vapor sample within the EA having the maximum total hydrocarbon concentration (i.e., sum of results for benzene, ethylbenzene,


28 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

toluene, xylenes, and naphthalene) in the depth interval of interest: 0 to 5 feet bgs for utility worker and 0 to 10 feet bgs for construction worker. For the routine site worker (vapor release to outdoor air above ground surface), the maximum total hydrocarbon concentration was selected from the shallowest vapor samples collected within the EA as the basis for the EPCs. This was considered reasonably conservative and most representative of the vapors migrating to the surface. The following samples were selected to represent the EPC based on the approach described above:

• EA 3: DG-SGO6 5' for all workers;

• EA 8: DG-SG113' for site worker and utility worker and DG-SG11 10' for construction worker;

• EA 9: DG-SG12 3' for all workers;




• EA 18: DG-SG16 10' for site and construction worker and DG-SGO7 5' for utility worker;

• EA 19: DG-SG1010' for all workers; and

• Eastern Area: DG-SB02 5' for all workers.

The soil vapor results were then used with appropriate volatilization models to estimate breathing zone concentrations; volatilization models included a trench air evaluation (VFt ) consistent with VDEQ guidance and a box model for ambient air evaluation (VF.) consistent with ASTM 2002 (see discussion of models in Section 3.5). The selection of maximum discrete soil vapor concentrations for quantitative assessment (i.e., to support EPC estimation) was made because the data are not distributed in a manner that supports calculation of a meaningful central tendency value. In addition, this method represents a conservative (reasonable maximum) approach to evaluating exposure within a subgrade feature of fixed and unknown future location using the available data.

The purpose of the soil gas sampling activities was to provide an initial evaluation of soil gas across the entirety of the refinery property with some soil gas sampling locations chosen to represent likely 'worst case' soil gas concentrations. The locations and depth intervals of the soil vapor points were selected to provide data that would best characterize potential releases from three potential subsurface source types for VOC vapors. These sources include the following: 1) free product trapped in soil pores or present on water table, 2) ground water with dissolved volatile constituents, 3) shallow soil impacted with VOCs. Multiple depths were selected to characterize the vertical distribution for the deeper source types and evaluate the potential attenuation effect that the varying lithology may have on the subsurface impacts.


29 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Figure 20 of Appendix C identifies the soil vapor sampling locations along with identification of EAs. Points targeted for the free product areas included the following: DG-SG02, DG-SG03, DG-SG05, DG-SG07, and DG-SG09. Depths include approximately 10 feet bgs, 20 feet bgs, and 45 feet bgs, field conditions permitting (e.g., formation tightness did not interfere with vacuum). Points targeted for the dissolved phase areas included the following: DG-SGO4 and DG-SG10. Depths include approximately 10 feet bgs, 20 feet bgs, and 45 feet bgs, field conditions permitting. Points targeted for the shallow soil areas included the following: DG-SG06, DG-SG11, DG-SG12, DG-SG13, DG-SG14, DG-SG15, DG-SG16, and DG-SG17. Depths included a mix of 3, 10, 15, and 20 feet bgs depending upon CI results.

Use of the discrete soil vapor sampling points to model breathing zone EPCs assumes that the trench or construction excavation intersects the location of maximum reported vapor concentration in the EA, or that the concentration in the sampled location is representative for the remainder of the EA. Based on the available vapor data, which demonstrate that vapor constituent concentrations varied significantly laterally and vertically, this is not likely an applicable assumption. However, it is used as a simplifying approach for this assessment that allows conservative estimation of potential risk, and serves to identify areas that warrant additional focus or definition when potential for unacceptable risk is identified.

The EPCs are summarized on Tables 3.1 through 3.14 for the various receptors and scenarios.

3.4 PHYSICAL AND CHEMICAL PROPERTIES

Select physical and chemical properties in support of risk calculations were taken from USEPA's Regional Screening Levels table, dated May 2014 and summarized in Appendix D-1.

3.5 VOLATILIZATION AND PARTICULATE EMISSION FACTORS

Volatilization factors were derived or identified for volatile constituents, defined as those chemicals having a Henry's Law constant greater than 1E-05 (atm-m3/mol) and a molecular weight less than 200 g/mol, using methods as approved in the Tier 3 Risk Assessment Work Plan.

VFs

The volatilization factors for the release of constituents in surface soil to ambient air (VFs) were taken from the USEPA's Regional Screening Levels table, dated May 2014, and are summarized on Appendix D-1.

Environmental Resources Management 30 G: \ 2016\ 0122128\ 23453Hrpt (rev).docx

VFa

The volatilization factors for the estimation of volatile constituents in ambient air (for routine site worker) using measured subsurface soil vapor concentrations (VFa) were calculated following Standard Guide for Risk-Based Corrective Action Applied at Petroleum Release Sites (ASTM, 2002) with an adjustment for depth to soil vapor sample in lieu of depth of ground water. The inputs and resulting VFa values are provided in Appendix D-2).

VFta

The volatilization factors for the estimation of volatile constituents in trench air using measured subsurface soil vapor concentrations (VFta) were calculated using the equation developed in CSAP Technical Review #18, Soil Vapor Attenuation Factors for Trench Worker Exposure (Meridian Environmental, 2012). The technical review documents the process of adjusting the VDEQ trench model to estimate trench air concentrations from a soil vapor source.

The VFta outlined in the technical review is consistent with the approach presented in the Tier 3 Risk Assessment Work Plan to modify the VDEQ model to utilize the soil vapor data collected at the site, i.e., to reflect soil vapor concentrations as the 'starting point' in lieu of ground water in the VDEQ model. The soil vapor concentrations at the site are believed to represent subsurface vapor from potentially multiple sources such as subsurface soil, dissolved phase ground water, and LNAPL. The benefits of starting with soil vapor data include the ability to simultaneously evaluate all sources of vapor, not just ground water, and elimination of the modeling step to estimate ground water to vapor phase partitioning. Additionally, dissolved phase ground water data are collected at the perimeter of the hydrocarbon plume beneath the Refinery during ground water monitoring, not within the footprint of the plume, and therefore provide limited support for modeling constituent release.

The Tier 3 Risk Assessment Work Plan identified the use of the VDEQ model for estimating trench air concentrations, but did not provide the model parameter values in detail. Therefore, the equation and assumptions are provided herein. VFta calculations are provided in Appendix D-3. The VFta equation is as follows:

VFw

The volatilization factors (VF,,,) for the estimation of volatile constituents released to air from surface water were based on the USEPA's default volatilization constant (0.5 L/m3) provided in the USEPA 1991 RAGS. This VF„, is based primarily on experimental data on the volatilization of radon from household uses of water, and assumes all uses of household water including showering, laundering, dish washing, etc. This provides a conservative factor for the outdoor release scenarios applicable to the risk assessment for the Refinery.

PEF

The particulate emission factor (PEF) is used to estimate the concentration of respirable particles and constituents in air due to fugitive dust emissions from soil. The USEPA's default PEF of 1.36E+09 m 3/kg (USEPA, 2002) was assumed for all COPCs.

3.6 EXPOSURE-SPECIFIC DERMAL ABSORPTION FACTOR

Dermal exposure to COPCs in water is expressed as a dermal absorbed dose (DAD), which relies in part on an absorbed dose per event (DAevent). The


32 G: \ 2016 \ 0122128 \ 23453F-it/at (rev).docx

DAevent is a function of the concentration in water multiplied by a chemical and exposure-specific dermal absorption factor, herein referred to as the DAevent factor. The DAevent factor was calculated in accordance with the USEPA dermal guidance (USEPA, 2004). Calculations for all COPCs are presented in Appendix D-4.

3.7 CHEMICAL INTAKE EQUATIONS

The risk assessment for COPCs, except lead, utilized the standard chemical intake equations recommended by USEPA guidance (USEPA, 1989, 1991, 1999, 2000, 2002, 2004, 2009, 2014) for estimating human intakes via ingestion, dermal and inhalation exposure routes for soil, ambient air, surface water, sediment, and ingestion of fish (as applicable). Chemical intake equations are shown for each scenario in Tables 4.1 through 4.16.


33 \ 2016 \ 0122128 23453Hrpt (rev).docx

4.0 TOXICITY ASSESSMENT

The toxicity assessment summarizes the pertinent data concerning toxicological properties of COPCs, and defines the toxicity values that were used in risk characterization.

For the quantification of risk estimates for COPCs, the carcinogenic and non-car-cinogenic effects of the COPC were taken into consideration. Toxicity data for COPCs were obtained from the following hierarchy of sources:

• USEPA's Integrated Risk Information System;

• USEPA's Provisional Peer Reviewed Toxicity Values;

• Agency for Toxic Substances and Disease Registry (ATSDR) Minimal Risk Levels;

• Ca1EPA Cancer Potency Factors and Chronic Reference Exposure Levels;

• USEPA's PPRTV Appendix; and

• USEPA's Health Effects Assessment Summary Tables.

Toxicity data for carcinogenic effects are expressed as a cancer slope factor (CSF) for oral pathways and unit risk factor (URF) for inhalation pathways. Toxicity data for non-carcinogenic effects are expressed as a reference dose (RfD).

Dermal toxicity values were not available in USEPA's toxicity databases. Therefore, oral toxicity values were extrapolated to the dermal route using an absorption adjustment as recommended by USEPA guidance (USEPA, 1989a). Gastrointestinal absorption factors (GIABS) were used to determine the appropriate extrapolation from oral toxicity factors. If the GIABS was >50%, the dermal reference dose and dermal slope factor were assumed to be equal to the oral reference dose and oral slope factor, respectively. If the GIABS was <50%, the dermal toxicity factors were estimated as specified below. The following absorption adjustments were made to the oral toxicity factors [i.e., oral reference dose (RfDo) or oral cancer slope factor (CSFo)], which are generally based upon administered doses, to extrapolate to the dermal route:

Dermal RfD = Oral RfD x GI-absorption

Dermal CSF = Oral CSF/GI-absorption

Risk evaluation of the dermal pathway for soil also required the use of a dermal absorption factor (ABS.d). The availability of chemical-specific data for dermal absorption of constituents from soil is limited. The USEPA's dermal guidance provides specific values for some constituents (USEPA, 2004). For all consti-tuents that did not have specific ABS.d values (USEPA, 2004), the following default ABS.d values consistent with USEPA guidance were assumed: 0% for volatile organic compounds (VOCs); 10% (0.1) for SVOCs; and 0% for inorganic


34 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

compounds. GIABS and ABS.d values for each COPC are summarized in Appendix D-1.

Where sub-chronic toxicity factors for non-carcinogenic effects were not available for a COPC, CHS reviewed the critical study used to develop chronic toxicity factors and removed the sub-chronic-to-chronic extrapolation uncertainty factor where available and appropriate. Otherwise chronic toxicity values were assumed when assessing sub-chronic exposures. Sub-chronic toxicity values were used in the evaluation of the utility worker and construction worker non- carcinogenic hazard In accordance with the KDHE letter dated February 22, 2012, sub-chronic toxicity values were used to evaluate construction worker exposure to on-site pond water and sediment.

Technical Memorandum #4 identifying chronic and sub-chronic toxicity values for use in the Tier 3 HHRA were approved by KDHE and USEPA. A listing of toxicity values, along with additional information such as target organs, modifying/uncertainty factors, and reference sources are presented here in the Tier 3 HHRA for each COPC. Table 5.1A and Table 5.1B summarize the oral/dermal non-carcinogenic toxicity data for chronic and sub-chronic effects, respectively. Table 5.2A and Table 5.2B summarize the inhalation non- carcinogenic toxicity data for chronic and sub-chronic effects, respectively. Table 6.1 summarizes the oral/dermal cancer toxicity data. Table 6.2 summarizes the inhalation cancer toxicity data.

Lead

EPA has determined that development of toxicity factors for inorganic lead is not appropriate given that lead bioaccumulates in the body, leading to significant variations in pre-existing body burdens. Standard methods for calculating risks are inadequate for lead given its known pharmacokinetics. In addition, there is widely established medical research on the health effects of lead, even at extremely low blood levels. In essence, it appears that there is no practical threshold for lead toxicity. Therefore, a RfD cannot be developed.

USEPA's approach to estimating lead toxicity and risk, as presented in the publication Recommendations of the Technical Review Workgroup for Lead for an Interim Approach to Assessing Risks Associated with Adult Exposures to Lead in Soil (1996) and subsequent updates, was used in the risk assessment to estimate lead risks to workers for soil and sediment, and to the recreational receptor for sediment. See Section 5.1.3 for details regarding risk characterization for lead in soil and sediment. Potential risk to the recreational receptor from lead in surface water at AOC 02 (Bull Creek) was evaluated using the Kansas Surface Water Quality Standards (2004), consistent with the approach specified in the Work Plan.

5.0 RISK AND HAZARD CHARACTERIZATION

Risk and hazard characterization is the integration of the findings of the exposure assessment and toxicity assessment. Carcinogenic risk and non- carcinogenic hazard estimates were derived for potential receptors and pathways that were identified in Section 3.1.

As a framework for understanding the quantitative carcinogenic risk and non- carcinogenic hazard estimates, they are discussed in the context of USEPA's acceptable ranges for carcinogenic and non-carcinogenic effects as presented in Role of Baseline Risk Assessment in Superfund Remedy Selection Decisions (USEPA, 1991). The referenced document identifies "where cumulative carcinogenic site risk to an individual based on RME for both current and future land use is less than 1E-04 and the non-carcinogenic hazard quotient (HQ) is less than 1.0, action generally is not warranted unless there are adverse environmental impacts". The carcinogenic risk estimates are also discussed in the context of KDHE's departure point of 1 x 10-5 carcinogenicrisk.

Chemical-specific applicable or relevant and appropriate requirements (ARARs) were also considered, where appropriate. Examples of ARARs include the Kansas Surface Water Quality Standards: Numeric Criteria and the federal Ambient Water Quality Criteria, and the federal Maximum Contaminant Levels (MCLs) While ARAR standards may be selected as the basis for cleanup goals at the facility, the risk assessment objectively quantified health risks in order to provide complete information to support decision-making.

Risk characterization for soil/sediment included the derivation of risk and hazard estimates for each potentially complete pathway for identified receptors for each EA (1 through 19), as applicable. Cumulative carcinogenic risk estimates and non-carcinogenic hazard indices were calculated to take into consideration the exposure for combined pathways for each receptor within each EA, and also combined pathways across media, where applicable. Potential impacts associated with lead were quantified separately from the aforementioned carcinogenic risk and non-carcinogenic hazard estimates for soil/sediment (see Section 5.1.3).

For the evaluation of surface water, the risk and hazard characterization included calculation of carcinogenic risk and non-carcinogenic hazard estimates for all surface water COPCs. Surface water COPCs were evaluated according to the process identified in Exhibit 1-2 of the USEPA's dermal guidance (USEPA, 2004). Therefore, dermal carcinogenic risk and non-carcinogenic hazard calculations were performed for COPCs where the dermal pathway is expected to contribute more than 10% of the oral pathway intake using conservative residential assumptions (USEPA, 2004). This was determined based on USEPA's recommendation for dermal evaluation presented in Exhibit B-3 for organic constituents and Exhibit B-4 for inorganic constituents (USEPA, 2004).

5.1 QUANTITATIVE RISK AND HAZARD CALCULATION METRICS

5.1.1 Hazard Index

Non-carcinogenic hazard was expressed as the ratio of the estimated intake of a constituent to the intake level that is not expected to produce adverse health effects. This ratio is the non-carcinogenic HQ.

Non-Carcinogenic HQ = Intake / Toxicity Factor

The non-carcinogenic Hazard Index (HI) was estimated as the sum of the HQs for all exposure pathways and constituents for a particular exposure scenario. Summing all COPC HQs may result in the overestimation of non-carcinogenic hazard. In instances where a HI exceeds 1.0, USEPA indicates that non- carcinogenic hazard can be segregated by target organs and mechanisms of action, i.e., only non-carcinogenic hazard from COPCs acting through the same mechanism and affecting the same target organs are summed to best represent potential non-carcinogenic hazard. A HI of less than 1.0 represents acceptable non-carcinogenic hazard according to USEPA guidelines because the estimated exposure is below the level identified as potentially resulting in adverse health effects. A HQ/HI greater than 1.0 indicates that there is potential for adverse health effects for that constituent under the specified exposure conditions.

5.1.2 Carcinogenic Risk

Carcinogenic risk is the excess probability of developing cancer as a result of the potential exposure quantitatively evaluated. Carcinogenic risks are expressed as unitless probabilities.

Carcinogenic Risk = Intake x Toxicity Factor

Carcinogenic risks were calculated under the conservative assumption that there is no threshold (level) below which carcinogenic effects do not exist and that a linear relationship exists between dose and response, even at low doses. The USEPA recommends an acceptable range of cumulative carcinogenic risk of 1x10-6 (one in one million) to lx10- 4 (one in ten thousand). Published KDHE Tier 2 cleanup values are based on an individual carcinogenic risk target of 1x10 -5

(one in one hundred thousand).

5.1.3 Lead

The characterization for lead is different from other non-carcinogenic COPCs in that a RfD for lead is not available. Developmental effects can occur even at very low levels. Therefore, establishment of a threshold level, such as needed for a RfD, is not appropriate. Potential impact to adults from lead exposure is evaluated relative to a target blood lead level for an indirect receptor (i.e., a fetus), not a direct receptor encountered at a site. In USEPA's Adult Lead Model, the target is a threshold of 10 micrograms per deciliter (ug/dL) of blood lead in a fetus. Lead impact is expressed as a probability of the fetal blood lead concentration exceeding the target blood lead level of 10 ug/dL given a


37 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

population lognormal distribution. A probability of greater than 5% generally represents unacceptable risk to lead exposure (USEPA, 1994).

5.1.4 Ground Water Protection

Ground water protection was evaluated by comparing reported soil concen-trations to ground water protection standards derived in accordance with the USEPA's Soil Screening Guidance (USEPA, 1996). For purposes of the risk assessment, the ground water was considered a (hypothetical) potential drinking water resource beneath the Refinery. Parameter input values (e.g., soil properties, infiltration rates, depth to water, EA dimensions; see Appendix E) were previously presented in the RBSE as part of an initial screening for ground water protection. In the RBSE, the hydraulic gradient and length of source area in the direction of ground water flow for each EA were identified and the most conservative value was applied to all EAs for screening purposes. For the Tier 3 HHRA, the previously presented EA-specific values for hydraulic gradient and length of source area in the direction of ground water flow were utilized to develop ground water protection soil levels for each EA. The values are still referred to as Soil Screening Levels (SSLs), consistent with the terminology from the source document, USEPA's Soil Screening Guidance.

5.2 SUMMARY OF RISK AND HAZARD ESTIMATES

Carcinogenic risk and non-carcinogenic hazard estimates were calculated for each potential exposure scenario by receptor. A summary of the cumulative carcinogenic risks and non-carcinogenic hazards under RME scenarios, and lead probabilities, are provided for each EA in Appendix F. The detailed carcinogenic risk and non-carcinogenic hazard calculations by exposure route are provided in Table 7.1 through 7.16, in RAGS Part D format. A summary of the carcinogenic risks and non-carcinogenic hazards across media are provided by EA and receptor in Table 9.1A through 9.20C, also in RAGS Part D format. Consistent with USEPA RAGS Part D table instructions, Table 10.1A through Table 10.7A present the carcinogenic risk and non-carcinogenic hazard estimates "that may trigger the need for remedial action." Therefore, Tables 10.1A through Table 10.7A provide a summary for the EAs in which cumulative carcinogenic risk estimates exceed target range (>10 -4) and non-carcinogenic hazard estimates exceed the threshold (HI>1.0) after target organ segregation is considered. To support a focus on the risk-driving pathways and constituents, these tables specifically identify the media in which the exceedance occurs, and the COPCs within those media which individually exceed the target or significantly contribute to the cumulative exceedance. The cumulative non-carcinogenic HI was segregated by target organ systems in Tables 10.1A through 10.7A, where appropriate. The detailed calculations of lead probabilities for exposure to lead in soil and sediment are provided in Appendix G.

5.2.4 Recreational Receptor

EA 2 (AOC 02 Bull Creek)

The calculated carcinogenic risk and non-carcinogenic hazard estimates for the recreational receptor exposure scenarios for EA 2 were within the USEPA target cumulative carcinogenic risk range of 1x10- 6 and 1x10-4 and non-carcinogenic HI less than 1.0. Lead probabilities were less than the target 5 percent, using both standard assumptions and more conservative assumptions evaluated in a sensitivity analysis (to address the fact that the receptor age range included adolescents). Risk estimates were also less than 1x10- 5 .

EA 17 (Former Pitch Pit)

Following waste removal activities that have been completed, the calculated carcinogenic risk and non-carcinogenic hazard for the recreational receptor exposure scenario for EA 17 were within the USEPA target cumulative carcinogenic risk range of 1x10-6 and 1x10-4 and non-carcinogenic HI less than 1.0. Benzo(a)pyrene in soil exceeded a carcinogenic risk of 1x10 -5 with estimated risk of 1.3x10-5.

5.3 DISCUSSION OF RISK AND HAZARD ESTIMATES FOR RECEPTOR SCENARIOS

The following observations are made based on the summary of constituents exceeding 10-5 or 10-4 carcinogenic risk levels and non-carcinogenic hazard index of 1, provided in Section 5.2:

• The COPCs in soil that result in direct contact carcinogenic risk estimates above 1x10-5 for industrial receptors (routine, utility, or construction worker) are the PAHs benzo(a)pyrene and dibenz(a,h)anthracene. Benzo(a)anthracene, benzo(b)fluoranthene, and ideno(1,2,3-cd)pyrene contribute to direct contact risk above 1x10-5 in one EA. Arsenic also contributes to direct contact risk above lx10-5 in two EAs, and a discussion of background contribution to arsenic risk is provided in Section 5.7.

• Benzo(a)pyrene is the single constituent that contributes to direct contact carcinogenic risk above lx10-5 for the recreational receptor at the former Pitch Pit. Benzo(a)pyrene was detected in 2 of 11 samples that characterize risk for this receptor, and the maximum reported concentration was identified as the EPC for risk estimation.

• Hydrocarbon mixtures including gasoline range, diesel range and motor oil range hydrocarbons contribute to non-carcinogenic HIs exceeding 1.0 in five EAs for direct contact by non-routine industrial receptors (utility or construction worker). The confidence in risk characterization for these mixtures therefore warrants further discussion (see Section 5.6). It is noted that in the absence of information on target organs for the KDHE-published toxicity values used for petroleum hydrocarbons, refinement of HIs based on


target organs was not performed for these hydrocarbons. The HQs for these hydrocarbon ranges were summed for a total HI, which may overestimate the non-carcinogenic hazard

• Soil vapor samples collected in EAs 9, 10, and 13 represent potential carcinogenic risk and non-carcinogenic hazard for intrusive activities should the conditions be similar to those assumed for this simplified assessment of inhalation for the utility and/or construction workers. Review of available vapor data indicates constituent concentrations were notably elevated in samples collected within the upper 10 feet bgs in these EAs, and that the results appear to represent 'hot spots' for soil vapor concentrations.

To support an understanding of the distribution of the "risk driving" constituents in EAs where potentially significant carcinogenic risk or non- carcinogenic hazard was estimated, the following figures are provided. The figures identify the concentrations of constituents identified as exceeding the USEPA target risk range (carcinogenic risk > 10-4; HI>1), within 0 to 10 feet bgs exposure interval, for the specific EAs and environmental media of concern. Additional data are available at deeper depths and are included in the comprehensive data set in Appendix L.

• Figure 5-1: Hydrocarbon mixture concentrations in EA 5 soil.

• Figure 5-2: Diesel range hydrocarbon mixture concentrations in EA 7 sediment.


• Figure 54: Benzene, ethylbenzene, and xylenes concentrations in soil vapor samples collected in the general vicinity of EAs 9 and 10.


Although carcinogenic risk falls within USEPA target range for the recreational receptor at EA 17 (former Pitch Pit), Figure 5-6 also provides the distribution of benzo(a)pyrene concentrations in EA 17.

5.4 GROUND WATER PROTECTION DEMONSTRATION

There is known impact to ground water at the Refinery due to historical petroleum hydrocarbon releases resulting in migration of free phase hydrocarbons to ground water at the Refinery. Routine LNAPL recovery is currently performed to reduce the LNAPL volume in contact with ground water. Additional sources of potential impact to ground water include free phase hydrocarbons in subsurface soil (see discussion in Section 5.5) and COPC-impacted soil. The USEPA ground water protection (GWP) methodology and partitioning theory was used in this risk assessment to evaluate the latter potential source, i.e., potential effect of COPC-impacted soil on the underlying ground water.

Appendix E-1 presents a comparison of EPCs to GWP soil screening levels (SSLs) for each soil/sediment COPC by EA. Supporting GWP SSL calculations for each


43 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

COPC and EA are provided in Appendices E-2 through E-16. Benzo(a)anthracene, naphthalene, gasoline range hydrocarbons, and total petroleum hydrocarbons exceeded their respective GWP SSLs in one or more EAs. Each of these constituents are discussed in detail below.

Benzo(a)anthracene in EA 19 exceeded the GWP SSL. Benzo(a)anthracene exceeded in one sample location: A0C01/SB02 (0 to 1 foot) with a reported concentration of 10 mg/kg. Benzo(a)anthracene in the deeper sample (9 to 10 feet) at this boring was reported as Not Detected. Synthetic Precipitation Leachate Procedure (SPLP) was performed on soil sample A0C01/DG-SB08 (0-1'), which is a resample of A0C01/SB02 (0-1'). Benzo(a)anthracene was reported as Not Detected in the SPLP analysis. These results, and the very low solubility this compound, indicate that benzo(a)anthracene soil concentrations in EA 19 are not likely to adversely impact the underlying ground water.

Naphthalene in EAs 3, 7, 8, 10, and 19 exceeded the GWP SSL. Naphthalene concentrations were further evaluated for these EAs as discussed below.

• Naphthalene concentrations in EA 3 exceeded the GWP SSL (0.14 mg/kg) in eight boring locations. The highest reported naphthalene soil concentration of 26.5 mg/kg was associated with sample SMU31D/DG-SB08 (0 to 1 foot). Naphthalene concentrations in this boring decreased with depth, with concentrations at 12 to 13 feet and 17 to 18 feet reported as Not Detected.

• Naphthalene concentrations in EA 7 exceeded the GWP SSL (0.60 mg/kg) in eight sediment and one soil (beneath sediment) locations. The highest reported naphthalene soil concentration of 9.45 mg/kg was associated with sample SMU09/DG-SB05 (0 to 0.5 foot bgs). Naphthalene concentration in this boring decreased with depth, with the next deeper sample (soil 0.5 to 1.5 foot bgs) having reported naphthalene concentrations of 0.645 mg/kg (using USEPA method 8270C) and <0.0129 (using USEPA method 8260B), which are considered consistent with or less than the GWP SSL.

• Naphthalene concentrations in EA 10 exceeded the GWP SSL (0.23 mg/kg) in one boring location: SMU11/DG-SB08, at 14 to 15 feet and 18.5 to 19.5 feet. The highest reported naphthalene concentration was 21.2 mg/kg at 18.5 to 19.5 feet; a second analysis of naphthalene at this depth had a reported concentration of 7.78 mg/kg. Deeper samples were not available for this boring location.

• Naphthalene concentrations in EA 8 exceeded the GWP SSL (1.2 mg/kg) in eight boring locations. The highest naphthalene soil concentration of 47 mg/kg was from sample SMU31B/SB03 (1 to 2 feet). Naphthalene in the deeper sample (19 to 20 feet) collected at this boring location was reported as Not Detected. SPLP was performed on soil samples SMU31B/DG-SBO3A and SMU31B/DUP, which are resamples of SMU31B/SB03 (0 to 1 foot) with a naphthalene concentration of 46 mg/kg. Naphthalene was reported at 5.2 ug/L and 16.4 ug/L, respectively, in the SPLP analyses. Applying the site- specific dilution factor (729) estimated for EA 8 (in Appendix E), the resulting


44 G: \ 2016 \ 0122128 \ 23453}irpt (rev).docx

estimates of potential ground water concentrations of 0.0071 ug/L and 0.022 ug/L are less than the USEPA tapwater RSL of 0.17 ug/L.

• Naphthalene concentration in EA 19 exceeded the GWP SSL (0.077 mg/kg) in one sample location: A0C01/SB02 (0 to 1 foot) with a reported concentration of 0.54 mg/kg. Naphthalene in the deeper sample (9 to 10 feet) at this boring was reported as Not Detected. SPLP was performed on soil sample A0C01/DG-SB08 (0-1'), which is a resample of A0C01/SB02 (0-1'). Naphthalene was reported as Not Detected in the SPLP analysis.

The naphthalene concentration data support that attenuation occurs with depth in site soil, as documented in the vertical profiles above. Leachate testing of soil collected in the boring location with the highest naphthalene concentration noted above (SMU31B/SB03) demonstrated that naphthalene was detected in leachate at low levels. Site-specific estimates of potential dilution and attenuation, considering factors such as depth to ground water, infiltration rate, and estimated source size, suggest that the measured leachate concentration will not contribute significantly to ground water impact.

Gasoline range hydrocarbons in EA 18 soil exceeded the GWP SSL. One soil sample was collected in a location with elevated gasoline range concentrations during the data gap sampling event in EA 18 and analyzed for petroleum fractions. Only the aliphatic C6 fraction was reported detected. The concentration of 34 mg/kg was less than the gasoline range hydrocarbon GWP SSL of 240 mg/kg. The petroleum fraction results suggest that leaching at concentrations of concern is not expected for gasoline range hydrocarbon concentrations in soil at EA 18.

Total petroleum hydrocarbons in soil at EAs 1, 5, 10, 13, 17, and 18 exceeded the GWP SSL, for which the SSL was developed using gasoline range hydrocarbon target ground water concentration (and physical properties) as surrogates. Laboratory analyses of the more specific hydrocarbon mixtures (gasoline range hydrocarbons, diesel fuel, and motor oil) in the same samples resulted in reported concentrations below the GWP SSLs either developed in the RBSE (initial screen for COPC selection) or developed herein (EA-specific SSLs). The more specific fuel-type analyses provide the more informative results, and are available for the same soil samples.

Based upon the reported concentrations of COPCs remaining in soil and sediment, and use of standard partitioning models with site-specific inputs, the concentrations are not estimated to provide a source of leaching to ground water at concentrations resulting in unacceptable risk/hazard

The historical NAPL releases form the more significant source for ground water impact at the site, and interim measures to address the NAPL plume and impacted ground water are ongoing.

5.5 NAPL

The NAPL present beneath the refinery at the ground water interface is delineated, hydraulically contained, and the extent is bounded within the property boundary. LNAPL is periodically removed from on-site wells, containing sufficient LNAPL thickness, using portable vacuum extraction "slurping" equipment. Information on the hydrocarbon plume and recovery efforts is provided to KDHE in routine ground water monitoring reports.

Free phase hydrocarbons were observed in unsaturated soil within certain borings installed during the Comprehensive Investigation. Additional borings were installed during the data gap sampling event to delineate the NAPL observations in soil. The following EAs and associated soil borings were observed to contain free phase hydrocarbons in soil:

• EA 8 - SMU25/SB06 (4-8 feet); SMU25/SB04 (6.5-12.5 feet); SMU31B/SB02 (9.5-13 feet); SMU25/DG-SB08, SMU25/DG-SB10, SMU25/DG-SB11, SMU25/DG-SB12, SMU25/DG-SB14, SMU25/DG-SB15, and SMU31B/DG-SB06, typically between 20 to 25 feet; SMU25/DG-SB14 (12-13 feet); and SMU25/DG-SB15 (various intervals from 4 to 14 feet). Additional delineation to the west may be warranted based upon the delineation and observations provided in the Data Gaps summary report.

• EA 11 -- SMU13/SB03 (9-20 feet) and SMU13/DG-SB08 (45-50 feet). This EA is contained within the process area, and surrounded by other EAs where borings were free of NAPL. Further delineation is not necessary.

• EA 18 -- A0C01/SB09 (5-6 feet) and A0C01/SB15 (3-4 feet). Further delineation is not necessary based upon the delineation and observations provided in the Data Gaps summary report.

Analytical data were available for soil samples collected from one or more of these locations in each EA, and review of the data confirms that elevated concentrations of petroleum hydrocarbons were reported in the soil near the NAPL occurrences. The reported concentrations were included in the risk evaluation, and result in some of the higher non-carcinogenic hazard estimates. The non-carcinogenic hazard estimates for the Utility and Construction Workers for EA 8 and EA 11, for example, are consistent with the field observation of hydrocarbon presence in the shallow subsurface in these areas.

Additional field evidence of hydrocarbon impact to soil was observed and documented in the boring logs during the investigations, including hydrocarbon staining or odor, with no NAPL present. Samples were collected for laboratory analysis based on these (and additional) field screening indicators, and the results were included in this risk evaluation.

5.6 TOTAL PETROLEUM HYDROCARBONS

Because petroleum mixtures are present in the subsurface at the site and were identified to contribute to the exceedance of target non-carcinogenic hazard in certain EAs, further discussion of the site-specific hydrocarbon data is provided. As discussed in Section 2.3.1, thirteen samples were collected during the data gap sampling event specifically to further characterize some of the most elevated hydrocarbon concentrations reported in soil during the CI. This section evaluates the results from Methods OA-1/OA-2 relative to the petroleum fraction results from TCEQ Texas 1006 Method, and discusses implications for risk characterization.

Methods OA-1/OA-2 were standard methods for analysis of petroleum hydrocarbons at sites across Kansas during the time of the comprehensive site investigation for the Refinery. Analytical results reported using these methods and the similar USEPA Method 8015 are useful in identifying the presence of hydrocarbons and initial estimates of human health risk. Where hydrocarbon risk is a driver for potential corrective action, additional methods such as TPH fractionation can provide valuable information to support an increased understanding of the site-specific material, resulting non-carcinogenic hazard, and best corrective action options for the specific material present.

Appendix H presents a summary of the paired analytical data for petroleum product mixtures (reported using Methods OA-1/OA-2) and petroleum hydrocarbon fractions (reported using Texas Methods 1005 and 1006). Thirteen data pairs were available for evaluation. Generally, the results for hydrocarbon fractions were substantially less than petroleum products. The difference is generally attributed to the silica gel cleanup step included in the fractionation method, which removes non-hydrocarbon components from the sample during analysis. It is also recognized that a factor which introduces variability in this comparison is that locations were "resampled" following review of the CI data to support fraction analysis. Therefore, the ability to sample the same location (using sample coordinates), time for potential weathering, and natural soil heterogeneity, introduce variability in the sample results/comparison.

In instances where high "total petroleum hydrocarbons" concentrations were reported with Methods OA-1/OA-2, the fraction result did not exhibit a similar response. For example, in EA 1 sample location SMU26/SB01/0-1, total petroleum hydrocarbons were reported at 55,000 mg/kg and the fraction data were Not Detected with a detection limit of 139 mg/kg. Similarly in EA 17, sample location SMU33/SB01/3-4 total petroleum hydrocarbons were reported at 12,000 mg/kg and the fraction data was Not Detected for all fractions, except Aliphatics C6 with a concentration of 35.1 mg/kg. EA 18 sample location HCEP/SB25/3-5 had a reported total petroleum hydrocarbons concentration of 11,200 mg/kg and the fraction data were Not Detected for all fractions in both the sample and field duplicate. Locations were duplicated laterally to within + 2 feet and the sample depth interval was sampled. While inability to exactly duplicate a prior sample is a factor in the differing results, given these differences

and the guidance of USEPA (Provisional Peer-Reviewed Toxicity Values for Complex Mixtures of Aliphatic and Aromatic Hydrocarbons, 2009) on the preferred use of fraction analyses in quantitative risk assessment, these results suggest that a conclusion of significant non-carcinogenic hazard based solely on total petroleum hydrocarbon results from Methods OA-1/OA-2 is not reliable.

EA 1 sample location SMU26/SB02/0-1 had an elevated concentration of motor oil (23,000 mg/kg). The corresponding fraction data showed that aromatic >C21 - C35 was detected at 131 mg/kg while all other fractions were Not Detected.

Where elevated concentrations were reported for gasoline range hydrocarbons, concentrations in the corresponding fractions were lower. Specifically, EA 10 sample location SMU 11/SB03/3-4 had gasoline range hydrocarbons reported at 1,100 mg/kg. The corresponding fraction analysis detected aliphatic C6 at 55.3 mg/kg while all other fractions were Not Detected. Similarly, EA 18 sample location AOC 01/SB13/4-5 had gasoline range hydrocarbons reported at 810 mg/kg; the corresponding fraction analysis detected aliphatic C6 at 33.7 mg/kg. Analysis of the original sample in 2003 for the more toxic components expected in gasoline (e.g., benzene, toluene, ethylbenzene, xylenes) indicated the compounds were not present (Not Detected), providing support for the low level of hydrocarbon detected in the subsequent fraction analysis.

In samples with moderately elevated diesel fuel concentrations (EA 18 sample locations A0C01/SB13/4-5 and SMU15/SB04/0-1), fractions typically associated with diesel (e.g., >C8-C10, >C12-C16, and >C16-C21) were Not Detected.

In EA 8 sample location SMU31B/SB03/0-1, diesel fuel was reported at 35,000 mg/kg. Concentrations in fractions support the presence of diesel range hydrocarbons. The individual fraction concentrations were lower than the diesel range mixture concentration reported for Methods OA-1/OA-2, with the fraction results providing a greater amount of information to support detailed risk assessment. Additionally, the aromatic fraction (>C21-C35) associated with heavy petroleum had the highest concentration, yet heavier petroleum products such as motor oil and fuel oil were Not Detected using EPA Method 8015.

In EA15 sample location SWMU31A/SB05/9-10, reported fraction concentrations exceeded the mixture results reported by OA-1/OA-2. This result demonstrates the variability that occurs in soil sampling, even when targeting the same location coordinates.

The comparison of hydrocarbon results underscores the differences in the reported concentrations that can be obtained by Methods OA-1/OA-2 (and USEPA Method 8015) and a fractionation method. Recognizing there are limitations to the comparisons provided due to "resampling", based on literature and the available site-specific fraction data, it is likely that petroleum hydrocarbon concentrations reported by Methods OA-1/OA-2 (and EPA Method 8015) are biased high based on limitations of the laboratory method (Lundegard

and Sweeney, 2004; Zemo and Foote, 2003; Zemo et al., 2013). Resulting non- carcinogenic hazard estimates for these analytes may be overstated.

CHS recognizes that soil areas containing high petroleum hydrocarbon concentrations may warrant interim and/or final remedy, and the locations and extent will be determined with KDHE and USEPA input through the CAS process. Given the current USEPA guidance for reliance on fraction results in quantitative risk evaluation, and the availability of validated laboratory methods for fraction analyses, it is recommended that risk management decisions related to petroleum hydrocarbons make use of the current guidance/methodology for hydrocarbon fraction analyses to the extent practicable, including KDHE's BER-041 policy on TPH characterization, remediation, and management (KDHE, 2015). Should refined risk characterization be needed to support decisions regarding risk management for petroleum hydrocarbon mixtures, use of the available site-specific fraction data and collection of additional samples for analysis from critical locations (as needed) are recommended. CHS will work with KDHE and USEPA to determine specific methods of further analysis as part of the CAS for any EAs warranting additional study of petroleum hydrocarbon mixture concentrations and potential non-carcinogenic hazard

5.7 RISK ATTRIBUTABLE TO BACKGROUND CONCENTRATIONS

Potential risks at the site are a combination of risks resulting from constituents released through historical Refinery operations and risks from naturally- occurring background constituent concentrations. In order to assess the contribution of background concentrations to total site risk, a statistical background evaluation was completed for certain inorganic constituents. Formal statistical testing was agreed upon by CHS and KDHE prior to the submittal of the initial RBSE. A background evaluation was completed, but deferred for presentation until the risk assessment at the request of KDHE and USEPA. The evaluation was updated as necessary to reflect changes in EAs and available data. Evaluation of the background data sets and presentation of the design and methods for determination of site background for inorganics in soil and sediment were provided in the approved Technical Memorandum #5 (Background Evaluation: Design and Methods), a copy of which is included in Appendix J of the Tier 3 HHRA for ease of reference.

USEPA guidance and relevant scientific literature were used to select statistical methods appropriate to the site-specific data sets. Relevant USEPA and KDHE guidance includes, but is not limited to the following guidance documents:

• Determination Of Background Concentrations Of Inorganics In Soils And Sediments At Hazardous Waste Sites (USEPA, 1995);

• Guidance for Comparing Background and Chemical Concentrations in Soil for CERCLA Sites (USEPA, 2002); and

• Role of Background in the CERCLA Cleanup Program (USEPA, 2002).


49 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

The most recent version of ProUCL software available at implementation was used to conduct the statistical background evaluations presented in Technical Memorandum #5 (e.g., background outlier and distribution testing, calculation of background threshold values). The Memorandum outlined evaluation methods, such as two-sample hypothesis testing, to be performed for background comparisons when sufficient data are available. A single inorganic constituent, arsenic, is evaluated in detail herein because estimated carcinogenic risk from arsenic may contribute significantly to cumulative carcinogenic risk exceeding lx10-5 and the reported arsenic concentrations may fall within background range. Arsenic in soil in EAs 11 and 18 was evaluated statistically to gain an understanding of whether background levels are contributing significantly to the estimated carcinogenic risk or non-carcinogenic hazard

In accordance with recommendations provided in Technical Memorandum #5, the evaluation included visual (graphic) assessment of the data, distribution testing, test of right tails (upper bounds), and test of central tendency. Sufficient data were available (n>8) to perform two-sample hypothesis testing. Graphs and test results are provided in Appendix I-1 for EA 11 versus background, and Appendix 1-2 for EA 18 versus background.

A review of the histograms, box plots and Q-Q plots generated for EA 11 compared to site background show that distribution and central tendency for arsenic in EA 11 are similar to site background, with EA 11 demonstrating more amplitude in the right-tail relative to the site background data set. Two data points in the EA 11 data set may potentially be outliers.

A review of the histograms, box plots and Q-Q plots generated for EA 18 compared to site background show that distribution, central tendency, and range for arsenic in EA 18 are somewhat similar to site background, with EA 18 demonstrating more amplitude in the right-tail relative to the site background data set.

Distribution testing was performed on the data sets for EA 11, EA 18, and site background. Data distributions were not discerned for EA 11 and site background, i.e., the data sets were not normally, lognormally, or gamma distributed. The data set for EA 18 followed an approximate gamma distribution.

Three two-sample hypothesis tests were performed: the quantile test (right tails); the Gehan test (central tendency); and the Tarone-Ware test (central tendency). Both the Gehan test and Tarone-Ware test are appropriate nonparametric tests of central tendency. A Form 1 test with 95% confidence was performed:

Ho = The arsenic concentration in the EA is less than or equal to the background concentration.

HA = The arsenic concentration in the EA is greater than background concentration.


50 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

The quantile test (right tails) for EA 11 versus site background resulted in a calculated alpha of 0.0575, which is equivalent to the critical test alpha of 0.058. This indicates that the right tail for EA 11 is less than or equal to site background. The results of the Gehan test and Tarone-Ware test, with probability values [p- values] of 0.498 and 0.593, respectively, were greater than the critical test alpha of 0.05 and indicate that the central tendency (median) value for EA 11 is less than or equal to site background. Therefore, arsenic in EA 11 is considered consistent with site background.

The quantile test (right tails) for EA 18 versus background resulted in a probability value of 0.0497, which is greater than the critical test alpha of 0.041. This indicates that the right tail for EA 18 is less than or equal to site background. The results of the central tendency tests for medians (4.5 mg/kg for EA 18 versus 3.7 mg/kg for site background) differed. The result of the Gehan test (p-value of 0.0255) indicates that the median arsenic concentration for EA 18 is greater than site background. The result of the Tarone-Ware test (p-value of 0.0628) indicates that median arsenic concentration for EA 18 is less than or equal to site background. Based on the results of the quantile test (right tails) and the Tarone-Ware test (central tendency), arsenic concentrations in EA 18 are considered consistent with site background.

Accordingly, the risk for site worker exposure to soil in EAs 11 and 18 are estimated to be attributed as follows:

EA Cumulative

Carcinogenic Risk

Carcinogenic Risk Attributable to

Background (Arsenic)

Carcinogenic Risk Attributable to Site

Activity (COPCs other than

arsenic) 11 1.2x10-5 4.5x10-6 7.5x10-6 18 1.2x10-5 3.4x10-6 8.6x10-6

The carcinogenic risks attributable to site operations in EAs 11 and 18 are estimated to be less than 1x10-5.

ProUCL outputs for the graphs, distribution testing, and hypothesis testing are provided in Appendix I.

6.0 UNCERTAINTY ANALYSIS

Risk assessment inherently involves uncertainties due to the assumptions that must be made regarding complex chemical behavior in the environment and in biological systems, as well as limited knowledge of events that will occur in the future. Therefore, although risk assessment is a valuable and appropriate tool for environmental decision-making, it is subject to the limitations of our current understanding of these environmental and biological systems. The following section describes some of the major sources of uncertainty in the risk assessment, efforts to minimize uncertainties when possible, and how uncertainties may affect the risk characterization.

Sampling Uncertainty

The CI of the Refinery SWMUs and AOCs was conducted in a phased manner based on priority assignments related to construction activities for the Clean Fuels Project and potential for human exposure. SWMUs and AOCs in which Clean Fuels Project-related construction activities were to be conducted were given the highest priority so that CHS could characterize potential sources and implement control measures during construction activities to minimize potential worker exposures.

The goal of a sampling program is to collect data which will represent the nature, extent, and magnitude of chemical constituents present in the media of concern. The amount of data collected in a sampling program and the placement of sample locations can affect the results of the exposure point concentration calculation because statistical inference is made about the entire affected area based upon the sample data. Potential exposure is estimated in this risk evaluation using UCL calculations based upon samples collected from environmental media of concern at the subject SWMUs and AOCs. The samples that were collected were intended to identify the magnitude of constituent concentrations present in areas where waste management activities were believed to have occurred. Sampling was biased towards locations that appeared to be impacted based on visual, olfactory, and instrument readings cues. This sampling strategy, which was described in Work Plans approved by the KDHE in two letters dated May 31, 2002 and September 16, 2002, and which was intended for nature and extent determination may produce artificially elevated risk estimates since the site samples were collected from the most apparently- impacted media encountered, and may not be representative of the entire EA.

Only shallow samples were collected at several boring locations, which may lead to an over-representation of exposure to shallow concentrations versus deeper concentrations for the construction worker evaluation (soil 0 to 10 feet bgs). However, this was limited to only six units (SWMUs 10, 21, 23, and 24, and AOCs 04, and 07) that were located above-ground, where any releases would have occurred onto surficial soil. The soil borings in these units were advanced to five feet bgs, which would be consistent with the potential exposure depth for many construction projects. The evaluation sought to include all available usable


52 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

data and exclusion of locations where only shallow data was collected may bias the results laterally. Such exclusion could result in high bias for the EPC, since in many cases, deeper samples were not collected because there was no evidence of deeper impact based on field observations. CHS believes that the exposure probability generally decreases with depth, and that it was appropriate to include as many samples laterally/spatially as are available, particularly since projects at the Refinery with subgrade construction are more typically completed to a maximum of 5 feet, and only rarely deeper than 10 feet.

Analytical Data

The results of the laboratory analysis of environmental media samples from the SWMUs and AOCs present a source of uncertainty due to the limitations of analytical technology, measurement error, and human error in the laboratory. An area of particular difficulty for environmental risk assessment is the handling of non-detect data points. Several constituents were reported as Not Detected above detection limits in media of concern (i.e., soil, soil vapor, surface water and sediment) at the site. These constituents were eliminated from further risk-based evaluation because, even if present, they are at negligible (low) levels in the environment and, therefore, are not likely to result in significant risk from potential exposures. Constituents that were reported above detection limits in media of concern were considered to be of potential concern for the site since their reporting in environmental media could represent a complete exposure pathway for potential receptors. In some cases, detection limits were elevated above target standards for several reasons, mainly limitations in the analytical method or instrument, dilution of select samples, and matrix interference. While this represents an uncertainty, the large body of data available reasonably represents potential risk. The constituents identified as providing the greatest contribution to carcinogenic risk or non-carcinogenic hazard in this assessment are consistent with those expected for refineries.

As discussed in Sections 2.3 and 5.5, a parameter termed total petroleum hydrocarbons was reported by laboratory for a limited subset of samples where light to heavy hydrocarbons fractions were present in the C14 to C30 plus range, but a positive profile match to a specific hydrocarbon product was not possible. The reported value was typically qualified by the laboratory with an explanation indicating that motor oil was used as the quantitation standard. This lack of specific identification creates uncertainty in the sample results and the subsequent use in the quantitative risk assessment. Without a cleanup step in the laboratory method, the total petroleum hydrocarbons results include naturally occurring organic matter and polar non-hydrocarbons (e.g., hydrocarbon degradation products) (Lundegard and Sweeney, 2004; Zemo et al, 2013). Toxicity data for petroleum hydrocarbon mixtures are based on use of surrogates. The combination of uncertainties in compound identity, concentration, and toxicity standard results in a low level of confidence for making risk management decisions based on this reported parameter.


53 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

Concentration data were reported for known petroleum mixtures such as gasoline range hydrocarbons, diesel fuel, fuel oil, jet fuel, kerosene, mineral spirits, and motor oil. The identified petroleum mixtures were assessed quantitatively using toxicity factors assigned to these specific mixtures and therefore represent a somewhat higher level of confidence. However, as discussed in Section 5.5, due to limitations of the laboratory method, resulting non-carcinogenic hazard estimates for these analytes may be overstated.

Data Screening

Screening constituents from further quantitative risk assessment presents an uncertainty in the risk assessment. In all EAs, at least one COPC was retained for quantitative risk assessment for one or more exposure pathways, therefore risk characterization has been provided for each EA. For EAs 14, 15, and 16, all constituents were screened from further evaluation for the ground water protection pathway. The use of conservative risk-based values in the screening process reduces the potential for eliminating a constituent or exposure pathway that would present a significant risk driver for the site.

The screening standards for use in the approved RBSE were USEPA Region 6 medium-specific screening levels (MSSLs). The MSSLs have been replaced with Regional Screening Levels (RSLs), which are now available for all USEPA regions. RSLs were used to screen data gap samples for the standard exposure pathways (direct contact and ground water protection). RSLs were also used to screen the relevant data for the non-standard exposure pathways (as discussed in Section 2.2), the results of which are presented in this Tier 3 HHRA report. Differences in the toxicity values and protocols used to develop MSSLs and RSLs present an uncertainty in this portion of the risk evaluation process. However, risk drivers (constituents providing the greatest contribution to risk) remain the same regardless of the screening process, namely PAHs. This outcome is consistent with risk assessments conducted at other petroleum refineries.

Determination of Exposure Point Concentrations

In the evaluation of constituents reported as detected, 95% UCLs on the mean concentration were used to calculate risk estimates for potential exposure scenarios where sufficient data were available. Non-detect results were included in statistical calculations to estimate exposure point concentrations, and were addressed appropriately by ProUCL in the determination of 95% UCLs on the mean. For constituent data sets with a low number of detected values, particularly in instances of only one detected value, there is increased uncertainty regarding the appropriateness and validity of the 95% UCL estimate. Maximum detected concentrations were used for data sets with less than 6 data points and for which UCLs exceeded the maximum value. Median concentrations were used for data sets of six or more samples with only one detected concentration reported. Uncertainty related to the true data distribution and true mean concentration is balanced/addressed by use of conservative approaches to estimate EPCs in most instances (i.e., the use of maximum


54 G: \ 2016 \ 0=28 23453Hrpt (rev).docx

reported concentrations for data screening and the use of an upper bound on the mean where possible).

As discussed in Section 3.3.1, there is a relatively high level of uncertainty associated with the EPCs identified for EAs for utility worker and construction worker trench air inhalation. Specifically, the use of a single (maximum concentration) discrete soil vapor sampling point to model breathing zone concentrations, and use of the concentrations to express potential risk for the EA, is an oversimplified approach. This approach was taken to make use of the available data, and is intended to provide an indication of the areas where additional focus is warranted for this potential pathway. Soil vapor data are available for a subset of EAs, and therefore characterization of this pathway was limited to those EAs in which soil vapor samples were collected. Based on the available vapor data, which demonstrate that vapor constituent concentrations varied significantly laterally and vertically, inference regarding soil gas concentrations beyond a localized area at the specific sampling location is not likely applicable. Risk estimates for the inhalation pathway in trench and construction zone air should be viewed as potentially applicable to the sampled location and immediate vicinity.

Exposure/Intake Assumptions

Risk assessments make assumptions about how and to what extent individuals might be exposed to the chemical constituents. Potential pathways of exposure or intake into the human body are considered including ingestion, inhalation, and dermal absorption. Assumptions on the level of intake are generally based on studies published in USEPA guidance or in the scientific literature. USEPA's default intake values are often upperbound values, and typically are higher than expected routine or long term intake. For example, the USEPA default skin surface area for dermal exposure was used at the request of KDHE and USEPA in this assessment. This default value assumes partial exposure of arms and legs, and is not realistic for refinery industrial workers who are required to wear flame retardant clothing (coveralls) which leaves only the face and hands exposed and who typically wear gloves for most tasks. Visiting contractors (e.g., utility workers and construction workers) at the refinery are subject to the same requirement. The use of these upperbound intake values in risk assessments generally results in the overestimation of risk.

Parameters that often have significant impact on the estimated risk include the EPC of the chemical, intake rates, and the frequency and duration of exposure. For example, a single concentration, (e.g., the maximum reported value or the 95% UCL on the mean) is assumed to be the concentration of a chemical to which exposure will occur throughout the exposure duration. Likewise, no variation in the frequency of intake or amount of intake is assumed throughout the exposure duration. This means that an individual is assumed to intake the same amount of media, in the same manner, containing the same chemical concentration, every day of the exposure scenario. Particularly in cases involving long-term exposure periods, it is unrealistic to assume that the individual would be exposed


55 G: \ 2016 \ 0122128 \ 234531-Irpt (rev).docx

uniformly to the maximum reported value or the 95% UCL on the mean over long-term periods of exposure. As a matter of practice and policy, this assumption is made, however, to reduce the chances of underestimating risk.

The ingestion rate for worker exposure to EA 7 pond sediment was based on an upper end default for soil exposure. This is likely to be overly conservative for the site worker scenario as it assumes that there is sufficient sediment entrained in pond water to result in the elevated ingestion rate during site worker activities such as fire suppression, slab washing, and aerator maintenance. Due to CHS's switch to use of well water for fire suppression and city effluent water for utility tasks (i.e., slab washing and aerator maintenance), there is no longer routine use of the pond water, limiting potential routine site worker contact with pond sediment for this activity. Currently, the EA 7 pond (10-Acre Lagoon) is primarily used for storm water overflow/surge protection. Use of the default soil ingestion value as a surrogate for sediment ingestion for the construction worker may also be overly conservative given that equipment set up during a hypothetical dewatering would transfer water directly from the pond to a holding container, thereby reducing worker contact with sediment. Accordingly, there is a high level of uncertainty and likely high bias associated with the sediment ingestion rates for EA 7.

There is uncertainty associated with the assumption that utility and construction worker scenarios will occur in each EA. These scenarios involve an assumption that workers will come in contact with soil deeper than 1 foot below grade, and that regular contact will continue for a duration of 6 years and 1 year, respectively. For some EAs (e.g., EA 7 and EAs in the process area), the likelihood of these activities occurring is very low. Reasonable maximum exposure assumptions for these scenarios were developed based upon careful consideration by CHS of past practices, current plans, and reasonable expectations for future refinery operations. However, uncertainty in the specific conditions of a future project (location, dimensions, project duration) is relatively high. For the purposes of estimating inhalation exposure for these workers, certain dimensions of a subgrade trench or excavation were assumed, and there is a high level of uncertainty associated with estimating such details Review of the inhalation intake estimates indicates that intake is most sensitive to the following assumptions: trench air exchange rate (which is a function of the trench width to depth ratio) and proximity to underlying soil vapor source. Relatively small changes to these assumptions can have a significant impact on the estimated intake and resulting estimated risk or hazard.

Intake estimates for carcinogenic PAHs [i.e., benzo(a)pyrene, dibenz(a,h)anthracene] in soil are important to the conclusions regarding cumulative carcinogenic risk for the Refinery EAs. The ingestion pathway results in the greatest contribution of risk for these constituents for workers and recreational receptors (for EA 17, Pitch Pit). Regarding the bioavailability of PAHs in soil and sediment, studies suggest that relative bioavailability of PAHs in soil is less than 100% for the human ingestion pathway. As agreed with KDHE and USEPA in Technical Memorandum #4, CHS has assumed 100%


56 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

bioavailability for the primary risk analysis because site-specific studies are unavailable to quantify reduced availability. However, as agreed, the sensitivity of the bioavailability assumption for carcinogenic PAHs [i.e., benzo(a)anthracene, benzo(a)pyrene, benzo(b)fluoranthene, benzo(k)fluoranthene, chrysene, dibenz(a,h)anthracene, indeno(1,2,3-cd)pyrene] was quantitatively assessed, and the following observations are provided in support of risk management decisions related to PAHs in soil and sediment. Brainard and Beck (1992) conducted a review of gastrointestinal absorption data for benzo(a)pyrene and recommended a bioavailability factor of 0.5 (50%) for ingestion of soil. Magee et al. (1996) derived an oral-soil absorption adjustment factor (AAF) of 0.29 for PAHs. The AAF was intended to correct for the differences in absorption between test studies and human exposure to environmental matrices. Using the more conservative bioavailability factor of 0.5 for the Refinery site, cumulative carcinogenic risk estimates are reduced below lx10-5 for the site worker for EA 18, for the utility worker for EA 19, and the recreational receptor for EA 17. Given the important role of the carcinogenic PAH constituents in final risk estimates for the Refinery, the bioavailability assumption warrants consideration in risk management discussions.

USEPA (2014) has recently modified several default exposure parameter values for standard scenarios, including the industrial worker scenario. Parameters included residential water ingestion rates, skin surface areas, worker soil adherence factor, adult body weight, residential exposure duration, and residential water exposure time. The net effect of these changes on USEPA RSLs was no change or a slight increase in the RSL (e.g., no change for benzo(a)anthracene in residential soil; 2.1 mg/kg versus 2.9 mg/kg industrial soil; 0.029 ug/L versus 0.034 ug/L tapwater). Given the marginal change, the direction of change, and the work involved in developing exposure parameter values agreed upon in the Tier 3 Risk Assessment Work Plan, CHS elected to retain the approved exposure parameter values for this evaluation. The overall impact of modifying these parameters in the intake estimates for the CHS Refinery scenarios is anticipated to be no effect or a decrease in risk/hazard.

Toxicity Evaluation

Toxicity factors used in the risk assessment are primarily derived from laboratory animal studies that were extrapolated to allow for evaluation of human effects. Although animal study data are derived from rigorous scientific experiments, there are a number of uncertainties involved in the use of these data for human effects. These include treatment of benign tumors as malignant, use of the most sensitive species and sex, and high dose to low dose extrapolation. A major subject of debate in toxicology is the applicability of test results generated from very high doses over a short time period to environmental exposures which are typically at extremely low doses perhaps over a longer period of time. In using high dose studies for carcinogenic risk assessment, EPA's extrapolation technique (the linearized multistage model) assumes that there is no threshold for adverse effect, even though there is evidence to indicate that this is not likely for some chemicals. For non-cancer reference doses, experimental data are


57 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

modified by several 10-fold uncertainty factors to account for extrapolation from animals to humans, short-term to long-term effects, and sensitive populations. Though these factors tend to be overly protective in most cases, toxicity factors may also underestimate the risk for chemicals that are more toxic to humans than to laboratory test species.

Sub-chronic toxicity factors were only available for a limited subset of constituents. Use of chronic toxicity factors in sub-chronic exposure scenarios, such as for the utility worker and construction worker, is a source of uncertainty that may overestimate the potential risk and hazard

Consistent with USEPA guidance (Supplemental Guidance for Assessing Susceptibility from Early-Life Exposure to Carcinogens, 2005), carcinogenic risk estimates for recreational receptor exposure to PAHs were adjusted to account for the mutagenic mode of action, where early life exposure may result in greater risk of developing cancer in childhood and adulthood. This was applicable for the recreational receptor at EA 2 (10 to 25 years old) and at EA 17 (10 to 18 years old).

Surrogate toxicity factors were used for evaluation of total petroleum hydrocarbons and motor oil. Gasoline range hydrocarbons was used as a surrogate for total petroleum hydrocarbons. Diesel fuel was used as a surrogate for motor oil. There is a high degree of conservatism associated with use of these surrogate toxicity factors. The toxicity factors for gasoline range hydrocarbons and diesel fuel were taken from KDHE's RSK Manual, as approved in the Tier 3 Risk Assessment Technical Memorandum #4.

Toxicity factors were not identified for four constituents: p-isopropyltoluene; acenaphthylene; benzo(g,h,i)perylene; and phenanthrene. P-isopropyltoluene was detected in 8 of 139 samples (6%) with detected concentrations ranging from 0.017 mg/kg to 3.21 mg/kg. This constituent is not a likely risk driver given the low frequency of detection. Acenaphthylene was detected in 11 of 158 samples (7%) with detected concentrations ranging from 0.0362 to 1.29 mg/kg. Benzo(g,h,i)perylene was detected in 85 of 166 samples (51%) with detected concentrations ranging from 0.00025 mg/kg to 205 mg/kg. Phenanthrene was detected in all samples with concentrations ranging from 0.0042 mg/kg to 287 mg/kg. It is anticipated that the quantitative risk evaluation of the remaining PAHs provides suitable representation of the risk for this class of compounds.

Utility of Risk Assessment for Select Exposure Scenarios

Potential risk/hazard to a recreational receptor exposed to on-site ponds was not quantified primarily because this exposure pathway is unlikely given the existing security and access restrictions. The Refinery is operationally active and has security and access control measures (e.g., security guard station, perimeter fencing, and identification badges) that are strictly enforced to meet federal security guidelines for chemical facilities. Additionally, the Refinery utilizes remotely controlled closed-circuit surveillance cameras and motion detectors


58 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

along the UP rail line, which provides the most logical point-of-entry to the ponds from outside the Refinery. Access to the ponds for hypothetical recreational purposes would require trespassing and breach of these security measures. The ponds are located in a relatively active area of the Refinery, and can be visually observed by workers who traverse the area to perform work- related activities. Since the pond areas within the Refinery boundaries are under an access-controlled environment, exposure to these water bodies is considered unlikely. Using the risk estimates for the site worker as a conservative proxy, the risk to a hypothetical recreational receptor from exposure to surface water and sediment in the on-site ponds (SWMUs 07, 08, and 09) would result in a cumulative carcinogenic risk estimate greater than 1x10- 5 but less than 1x10-4, and HI less than 1.0 using site worker assumptions. As indicated, single event trespassing is unlikely, and repeated occurrences even less likely.

At the request of KDHE and USEPA, a quantitative evaluation was performed for hypothetical construction worker exposure to surface water and sediment in on-site ponds (SWMUs 07, 08, and 09) during removal of sediment from the ponds. Based on the methods and equipment anticipated to be used to complete these tasks, exposure frequency was estimated to be 5 days or less for potential surface water exposure during the dewatering process, and 86 days or less for potential sediment exposure during the excavation and removal process. The standard risk assessment methods, including those used in the evaluation, are designed to quantify risk/hazard from repeated chronic exposure. There is uncertainty in application of these methods to evaluate acute, short-term exposures, such as those estimated for sediment and particularly so for surface water. Estimation of dose may be overstated, or not appropriate. Toxicity factors, typically developed for chronic or sub-chronic durations, present an additional source of uncertainty. Combined with the use of conservative exposure values for parameters such as ingestion rate and skin area exposed to surface water, the risk/hazard/blood lead probability calculated for this hypothetical scenario is likely overstated.

Risk Characterization

Summation of HQs and carcinogenic risks for multiple constituents in the same and/or across media is also a conservative protocol that is likely to result in high bias in the risk estimates, particularly in cases where the constituents being summed do not affect the same target organ(s) or have the same mechanism of toxicity. One method for handling the potential bias for non-carcinogenic hazard is to segregate HIs by target organs and mechanisms of action.

Chemical interaction may potentially result in toxic effects that are additive, synergistic, or antagonistic. Toxicity studies typically evaluate the toxic effect(s) of a single chemical on an organism and very few toxicity studies have evaluated the effects of multiple chemicals on an organism. The additive approach used in this risk assessment is a source of uncertainty but is standard practice. The potential impact on the risk assessment is not known because use of this


59 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

approach can either overestimate or underestimate risk, depending on the nature and characteristics of the COPC.

Background Evaluation

Many constituents detected in site samples occur naturally in the environment, most notably inorganics. Therefore, risk estimates provided herein for those constituents reflect the contribution of both site and natural sources. For purposes of supporting corrective action and risk management decisions for site- related impacts, the evaluation of background contribution to risk was limited to the constituent/EAs where carcinogenic risk above 1x10- 5 was estimated and the constituent contributing most to the estimated risk was suspected to potentially fall within background range. Arsenic in soil was evaluated for consistency with background levels in EAs 11 and 18. The data sets for background and EAs 11 and 18 had a sufficient number of samples to perform the background evaluation. The ProUCL software was used, and is a reliable, well vetted tool for statistical evaluations.

Uncertainty Summary

Although all risk assessments involve uncertainty, the risk assessment conducted for the subject SWMUs and AOCs was prepared utilizing risk protocols that attempt to reduce uncertainty in as many areas as possible. As a matter of practice and policy, subjective decisions for assigning risk assessment factors generally included a choice on the conservative end of the range of potential values. Site-specific information was used where possible and approved through the detailed Work Plan process. The evaluation provided in this risk assessment reflects reasonable maximum exposure to the best of CHS's knowledge, and incorporates a reasonable degree of conservatism.


7.0 CONCLUSIONS/RECOMMENDATIONS

The Tier 3 HHRA broadly included the following locations, constituents, and exposure scenarios:

• Thirty-six SWMUs and AOCs identified in the CAFO were subject to quantitative risk assessment. These SWMUs and AOCs were grouped into 19 Exposure Areas for evaluation of soil, soil vapor, surface water and sediment exposures, as applicable. Receptors included site worker, utility worker, construction worker, and recreational receptors, as applicable to the individual SWMUs and AOCs.

• COPCs identified through screening for further site-specific (Tier 3) risk assessment primarily consisted of: - Soil contact: arsenic, lead, carcinogenic PAHs, and petroleum mixtures. - Soil to ground water protection: selenium, PAHs, and petroleum

mixtures. - Soil vapor (e.g., to trench/excavation air): Benzene, ethylbenzene,

naphthalene, toluene, and xylenes based on soil vapor data. - Surface water: Limited list of metals, VOCs or PAHs depending on the

water body. - Sediment: Metals, PAHs, and petroleum mixtures for SWMU 07, 08, and

AOC 02. Metals, VOCs, PAHs, and petroleum mixtures for SWMU 09. The COPC list for sediment was based on constituents that were detected, as this medium was not subjected to quantitative screening.

• Receptor exposure scenarios, site-specific exposure assumptions, and risk assessment calculation methods were reviewed and approved by KDHE and USEPA through the detailed work plan process prior to preparing this assessment. Deviations from the approved methods were not identified. An additional method for EPC selection was identified for data sets characterized by a single detection and at least five additional non-detect results.

The following conclusions are made based upon completion of the Tier 3 HHRA:

• Cumulative carcinogenic risk and non-carcinogenic hazard estimates for multimedia exposure within the 19 EAs are below the upperbound USEPA cumulative target risk of 1x10-4 and HI of 1.0 for the routine site worker.

• Cumulative carcinogenic risk estimates for multimedia exposure exceeded the upperbound USEPA cumulative target risk of 1x10 -4 and/or HI of 1.0 for the utility worker and/or construction worker in Exposure Areas 1, 5, 7, 8, 9, 10, and 11. COPCs with significant contributions to cumulative risk/hazard were: - EA 1 (HI>1)- total petroleum hydrocarbons in soil, direct soil contact;

based on the non-specific nature of this parameter and availability of additional, more specific analyses, an HI<1 was identified.

- EA 5 (HI>1)- total petroleum hydrocarbons (non-specific) and motor oil range hydrocarbons in soil, direct soil contact. Cumulative non- carcinogenic HI = 1.7, and motor oil HQ = 0.88;


61 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

- EA 7 (HI>1)- diesel fuel range hydrocarbons in sediment, direct contact; - EA 8 (HI>1)- diesel fuel and motor oil range hydrocarbons in soil, direct

soil contact; - EAs 9 and 10 (risk >10-4, HI>1)- benzene, ethylbenzene, toluene, and

xylenes, inhalation pathway assumed for trench/excavation air (soil vapor source); and

- EA 11 (HI>1)- gasoline range hydrocarbons and diesel fuel, direct soil contact.

The hydrocarbon mixtures identified above were analyzed using methods OA-1, OA-2, and EPA Method 8015.

• Cumulative carcinogenic risk and non-carcinogenic hazard estimates for multimedia exposure are below the upperbound USEPA cumulative target risk of 1x10-4 and HI of 1.0 for recreational receptors assumed to visit Bull Creek and the former Pitch Pit.

• Lead concentrations in site soil and sediment did not result in calculated probabilities of fetal blood lead greater than the target five percent level.

• The site-specific GWP demonstration indicates that COPC concentrations reported in soil and sediment are not estimated to result in partitioning/migration to ground water resulting in concentrations above residential drinking water standards considering all available data. The assessment is based upon the reported concentrations of COPCs remaining in soil and sediment, leachate test results, and use of standard partitioning models with site-specific inputs. However, given the time over which the site has been used for petroleum processing and storage, and given the observations of impacts during excavation/construction activities at the refinery, particularly in the process area, it is reasonable to assume that locations of soil impacts have existed which could result in partitioning/migration to ground water. There is known impact to ground water at the Refinery due to historical petroleum hydrocarbon releases resulting in migration of free phase hydrocarbons to ground water beneath the Refinery. The historical NAPL releases form the more significant source for ground water impact at the site, and interim measures to address the NAPL plume and impacted ground water are ongoing.

• The Uncertainty Analysis recognized uncertainties due to the assumptions that must be made regarding complex chemical behavior in the environment and in biological systems, as well as limited knowledge of events that will occur in the future. Limitations to chemical analytical methods, risk and hazard calculation methods, and knowledge of human toxicity are inherent uncertainties in the standard risk assessment methods employed herein. Uncertainty factors identified to have the greatest potential impact on the assessment and conclusions presented herein for the Refinery include: relatively low confidence in the quantitative non-carcinogenic hazard estimates for OA-1, OA-2, and USEPA Method 8015 hydrocarbon mixture results; the assumption of 100% bioavailability of carcinogenic PAHs by the worker soil ingestion pathway; and use of soil vapor data from discrete


62 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

sample locations to support estimation of trench/excavation air concentrations for future (undefined) utility or construction work.

• Based on the outcomes of the site risk characterization, development of preliminary human health remediation goals is recommended following agency concurrence with the risk assessment. The preliminary remediation goals will be used to support the development of corrective action objectives in the Corrective Action Study (CAS). Opportunities to address and reduce uncertainties noted above will be identified as part of the CAS, and incorporated into preliminary remediation goals as appropriate.

• Evaluation of potential release of constituents, and potential exposure, to indoor air will be provided in an Addendum to the Tier 3 HHRA, and will incorporate recent additional data focused on assessing this potential pathway.

• No further RFI activities, except those related to evaluation of indoor air and NAPL delineation at EA 8, are required to comply with the CAFO requirement for a comprehensive investigation and risk assessment. Nature, extent, and delineation of environmental contamination were summarized in the Comprehensive Investigation Report, Document 5, dated October 13, 2005, and the Data Gap Sampling Event Summary Report, dated November 14, 2013. The conclusions of those investigations and reports are augmented by the risk characterizations and conclusions presented in this report.

A CAS will be completed to address the following:

• Potential exposure to soil for visiting contractors (i.e., utility workers and construction workers) or CHS employees involved in intrusive activities in Exposure Areas 5, 7, 8, 9, 10, and 11. The basis for this focus is the estimate of carcinogenic risk or non-carcinogenic hazard in excess of the USEPA target range.

• Soil areas containing NAPL.

• Development of corrective action objectives/remediation goals.

• Interim and final remedy for ground water.

7.1 CHS ACTIONS ADDRESSING RISK CHARACTERIZATION

Based on the sampling results and risk characterizations discussed above, CHS has undertaken a number of activities to address contamination and monitor/protect against potential receptor exposure. These include the following:

• CHS excavated and properly disposed waste materials from the former "Pitch Pit", which is located north of the Refinery, outside of the secured, fenced area (SWMU 33; EA 17).

• CHS is addressing potential exposure to elevated constituent concentrations in soil and soil vapor during intrusive activities. The Refinery excavation permit system is being revised to provide additional worker awareness and


63 G: \ 2016 \ 0122128 \ 23453Hrpt (rev).docx

increased monitoring and protection protocols in areas of potential environmental concern, consistent with Refinery operating procedures. CHS considers this a prudent action, or best practice, based upon the available sampling data.

• Soil removal actions performed as part of capital improvement projects in the tank farm area and vicinity, and which may impact (i.e., reduce) potential exposure, carcinogenic risk, and non-carcinogenic hazard in one or more EAs will be discussed in a forthcoming submittal once the final extent /impact of activities has been identified and evaluated. The submittal will document activities which may be considered as interim measures for soil.

• CHS has an active LNAPL recovery system in place since August 1987. Active pumping was performed from 1987 to 2008 and recovered over 200,000 barrels. Due to significant reduction of LNAPL mass at the ground water interface, the LNAPL recovery program has transitioned from daily pumping to monthly slurping (vacuum-enhanced pumping). Reports are submitted to KDHE on an annual basis.

• The existing ground water monitoring program verifies the extent of the LNAPL plume and the performance of recovery efforts within the Refinery, as well as ground water quality (i.e., lack of detected Refinery-associated constituents) near the perimeter of the property at the "zero line" monitor wells.

• CHS has developed and calibrated a detailed geologic model and a numerical ground water flow model for the Refinery area. The purpose of this model is to evaluate various water pumping scenarios to ensure that hydraulic capture is maintained across the full extent of the LNAPL and dissolved constituent impacts beneath the refinery. The model has been used to determine optimal pumping rates for existing supply wells and locations for new wells.

Notes:

Statistics: 95% UCL of Normal Data (95% UCL - N); 95% UCL of Lognormal Data (95% UCL - L); 95% UCL - Nonparametric (95% UCL - NP); 95% UCL - Other distribution (95% UCL - 0)

(1) Shapiro-Wilk Test indicates data are normally distributed. N = Normal (2) Shapiro-Wilk Test indicates data are log-normally distributed. L = Lognormal (3) Shapiro-Wilk Test and Anderson-Darling Test indicates data do not follow discernible distribution. NP = Nonparametric (4) Anderson-Darling Test indicates data are gamma distributed. 0 = Other (e.g., gamma) (5) Maximum concentration was used due to low frequency of analysis (data set n<6) or single detection (data set n>=6). (6) Maximum concentration was less than the 95% UCL on the mean. (7) Median concentration was less than the single detected value (data set n>6), and was selected as the exposure point concentration. [a] Only one sample was reported detected. Value shown reflects median result for the constituent.

The data distribution is provided in the rationale explanation, except where the maximum concentration was chosen over the 95% UCL on the mean. In those cases, the data distribution is noted following the 95% UCL on the mean.
