August 31, 2007 USS letter to Ms. Susan Johnson of MPCA presenting a work plan (Tar

Balls Between OU-I & J and Wire Mill Pond (OU-P) Sheen) for the recovery of tar balls

present in the area known as Tar and Tar Contaminated Soil in the Coke Plant Settling

Basin Located between (but not included in) Operable Units I and J (Tar Between OU-I

& J) and for sheen mitigation in this area as well as the Wire Mill Pond area.

September 21, 2007 MPCA letter (Approval with Modification of the Tar Balls Between

OU-I & OU-J and Wire Mill Pond (OU-P) Sheen Work Plan) to Mr. Mark Rupnow of

USS approving the tar recovery work plan.

Surface water sampling was performed during sampling events in May and October 2015 and

consisted of the collection and analysis of surface water samples from eight locations.

Surface water samples were analyzed for total metals, polycyclic aromatic hydrocarbons

(PAHs), cyanide, pH, total hardness, total suspended solids, and specific conductance.

Surface water samples collected from the Wire Mill Pond were also analyzed for diesel range

organics (DRO) and gasoline range organics (GRO). Groundwater monitoring was

performed during the May 2015 sampling event and consisted of collection and analysis of


February 2016

ES-2

groundwater samples from seven monitoring wells. Groundwater samples were analyzed for

total metals, dissolved metals, PAHs, cyanide, pH, and specific conductance.

The 2015 analytical results were consistent with historic groundwater results from the Site.

Excluding zinc, groundwater analytical results were reported at concentrations below

established evaluation criteria (EC). Consistent with past sampling results, the EC for zinc

was exceeded in monitoring well W10 with total and dissolved concentrations of zinc, both

reported as 130 micrograms per liter (µg/L). Monitoring well W8 also exhibited total and

dissolved zinc concentrations above the EC with a concentrations of 160 µg/L and 120 µg/L,

respectively. Elevated turbidity in the sample specimen appears to have contributed to the

reported result as W8 was pumped dry during well stabilization, inhibiting the collection of a

low flow/low turbidity sample. Additionally, between May 2014 and May 2015,

groundwater elevations decreased an average of 2.04 ft msl. Monitoring points W-7, W-8,

W-10, W-11, and W-13 had peak historic groundwater elevations in 2014, with increases of

1.23, 1.39, 1.99, 2.12, and 2.83 ft, respectively.

The 2015 analytical results were also consistent with historic surface water results from the

Site. None of the analytical results for the May or October 2015 surface water samples

exceeded established EC or sector specific benchmark monitoring values.

Biweekly inspections and maintenance of absorbent booms continued through 2015 at the

Tar Between OU-I & J location. The boom was replaced on July 17, 2015 and again on

August 31, 2015 after the boom was observed stained and saturated. The presence of tar

blooms were greater in 2015 than in 2014 and were observed consistently from July through

September 2015. The tar blooms observed are attributed to significantly low water levels

within the pond located between OU-I and OU-J combined with warm ambient temperatures.

The significantly low water levels appear to be the result of 1) the removal of approximately

14 beaver dams along the Unnamed Creek, 2) minimal stormwater run-off events, and 3)

minimal recharge of the Unnamed Creek. Between July and September 2015, AECOM

recovered approximately 150 gallons in total of tar-like substance. In addition to recovery of

observed tar blooms, additional absorbent booms were installed downgradient the pond

located between OU-I and J for added best management practice (BMP) implementation.

Containment, inspection, and recovery efforts will continue into 2016 while permanent

response actions for the Site are being assessed as part of the Site Feasibility Study (GLLAP

2014).


February 2016

ES-3

At the Wire Mill Pond, biweekly inspections by USS and maintenance of absorbent and

containment booms continued through 2015 with absorbent booms replaced as needed. The

containment and inspection efforts will continue into 2016 while permanent response actions

for the Site are being assessed as part of the Site Feasibility Study (GLLAP 2014).

In summary, analytical results for 2015 indicate no significant changes in surface water or

groundwater quality. The monitoring program continues to adequately monitor surface and

groundwater conditions relative to the site and no changes to the monitoring program are

recommended at this time.

1.0 INTRODUCTION

1.1 Background

The Site is located in Sections 34 and 35, T49N, R15W, and Sections 2 and 3, T48N, R15W in

the southern portion of the city of Duluth in St. Louis County, Minnesota. The Site location is

shown in Figure 1. The Site is located adjacent to the St. Louis River, which ultimately

discharges to Lake Superior, approximately eight miles downstream of the Site. A storm water

drainage way for the City of Duluth, referred to as the Unnamed Creek, flows through the

northern portion of the Site and discharges to the St. Louis River. The Site is bounded by the

Morgan Park neighborhood to the north, the St. Louis River to the east, Canadian National

Railway (CN) property to the west, and the USS Mud Lake property to the south.

The Site was the location of an integrated steel mill consisting of coke production, iron and

steel-making, casting, primary rolling and roughing, hot and cold-finishing, and galvanizing.

Major operations at the Site began in the early 1900’s and ceased in May 1979 with the

termination of the wire mill operation.

1.2 Purpose and Scope

This report discusses the sampling results from two scheduled surface water sampling events

and one groundwater sampling event performed in 2015 and compares the surface water and

groundwater quality results to historic site data and applicable state and federal water quality

standards. Surface water samples were collected in May and October 2015. Groundwater

samples were collected in May 2015. Sampling was performed in accordance with the April

2000 Monitoring Plan prepared by URS Corporation (URS), now AECOM, and the

subsequent May 26, 2000 Minnesota Pollution Control Agency (MPCA) approval letter.

This report presents the following information:

A description of the monitoring system and a site plan identifying the monitoring points;

A discussion of recent and long-term trends in the concentrations of monitored constituents and water level elevations;

A complete tabulation of analytical results to date;

A summary of surface water results in 2015;

A summary of groundwater results in 2015;

A discussion of notable or unexpected results and issues;

A discussion of the results of site visual inspections; and,

Recommendations for modifications or maintenance to the current monitoring system.

2.0 SURFACE WATER AND GROUNDWATER MONITORING PROGRAM

2.1 Hydrogeologic Setting

The Site is located in the Glacial Lake Duluth area, a lake plain located along the north shore

of Lake Superior, resulting in parent materials that consist of lake silt and clay (USGS 1979).

The regional geology of this area is the result of lava extruding from a rift in the continental

crust during the Keweenawan period of the Precambrian era. Erosion of these lava beds

formed red sandstone units that underwent glacial manipulation.

The bedrock geology of the Site consists of the Duluth Complex; a complex of early

Precambrian rocks that include multiple intrusions of gabbroic anorthosite, troctolite, gabbro,

anorthosite and felsic rocks (Sims 1970).

The Site has been extensively modified and filled during industrial development activity. Fill

material present at the Site consists of gravel, cinders, slag fragments and other materials.

The characteristics of the fill material vary throughout the Site. The native soils present

beneath the fill material consist of red-brown clay underlain, and at times interbedded with a

fine to medium sand (Barr 1986). The clay unit depth varies from 2 to 48 feet (ft) beneath

the ground surface, and the thickness ranges from 2 to 32 ft. Beneath the clay unit are

deposits of sand and gravel. Groundwater is generally encountered from 24 to 34 ft below

the ground surface (bgs). Groundwater elevations measured since 1999 have ranged from

606 to 627 ft above mean sea level (ft msl). Historic water level data and a hydrograph is

provided in Appendix A.

2.2 Surface Water and Groundwater Monitoring System

The groundwater and surface water monitoring system for the Site consists of seven surface

water sites, one seep, and seven groundwater monitoring wells. The sampling locations are

shown on Figures 2 and 3.

2.2.1 Surface Water

Surface water data is collected at the Wire Mill Pond, along the Unnamed Creek, and along

the St. Louis River. Chemical and field parameters measured for each monitoring station is

presented in Table 1. Monitoring at surface water locations is performed on a semi-annual

basis, immediately following rain events in April or May, and again in September or

October.


February 2016

2-2

Wire Mill Pond

Monitoring station WM-1 is located at the outlet of the Wire Mill Pond on the east side of the

railroad tracks (Figure 2).

Unnamed Creek

Four surface water monitoring stations are present along the Unnamed Creek: CP-1, CP-2,

CP-3, and CP-4 (Figure 2).

St. Louis River

Two monitoring stations are located within the navigational channel of the St. Louis River

upgradient and downgradient the site: SLR-1 and SLR-2. The locations of these monitoring

areas are shown on Figure 3.

2.2.1.1 Seep

One seep, station Seep-1, is monitored at the Site (Figure 2). Samples are collected from

Seep-1 for analysis on an annual basis, in April or May. Chemical and field parameters

measured are presented in Table 1.

2.2.2 Groundwater Monitoring Wells

Seven groundwater monitoring wells (i.e., W6 through W11 and W13) are monitored at the

Site. Well locations are depicted on Figure 2. Samples are collected for analysis from these

monitoring points on an annual basis, in April or May. Chemical and field parameters

measured are presented in Table 1.

2.3 Sample Collection Procedures

Surface water and groundwater samples were collected by AECOM in 2015. All laboratory

analyses were completed by TestAmerica in North Canton, Ohio. Prior to sampling the

monitoring wells, water levels and total depths were measured for each well. Each

monitoring well was stabilized to ensure that samples contain fresh formation water. While

the well was being purged, water quality parameters including pH, specific conductance,

turbidity, dissolved oxygen, and temperature were recorded after each well volume was

removed. Samples for laboratory analysis were collected only after a minimum of three well

volumes had been purged and/or stabilization of field water quality parameters had been

demonstrated. The 2015 stabilization forms are included in Appendix B. Shallow surface

water samples were collected while standing on shore or by wading to the sampling location.

Samples in the St. Louis River were collected from a boat. Sample bottles were submerged


February 2016

at each monitoring station and allowed to fill without losing preservative. If a sheen was

present, samplers attempted to collect the sheen within the sample container.

One trip blank was collected and analyzed during each sampling event. Following collection

of samples, sample containers were placed in coolers with ice. AECOM personnel shipped the

samples via FedEx to TestAmerica using standard Chain of Custody procedures.

3.0 RESULTS

3.1 Water Elevation and Groundwater Flow

Site-wide groundwater elevations were measured as part of the spring sampling event in May

2015. Water level data is summarized in Appendix A. Between May 2014 and May 2015,

groundwater elevations decreased an average of 2.04 ft msl. Monitoring points W-7, W-8,

W-10, W-11, and W-13 had peak historic groundwater elevations in 2014, with increases of

1.23, 1.39, 1.99, 2.12, and 2.83 ft, respectively.

The water elevation map for the May 2015 sampling event is presented as Figure 4.

Groundwater east of monitoring wells W-7 through W-13 appears to flow in an easterly

direction towards the St. Louis River. Groundwater north of monitoring well W-7 appears to

flow in a north-northeasterly direction towards the Unnamed Creek. Groundwater flow

directions appear to be consistent with surface topography and historic results. An 11 foot

drop in groundwater elevation between well W-8 and W-6 may be the result of local geology,

historic filling operations, and/or the proximity to the Unnamed Creek. Well W-8 is screened

from 28 to 38 ft below grade within native reddish brown sandy clay, fat clay, and clayey

sand; well W-6 is screened from 20 to 30 ft. below grade within gravelly sand fill (Barr,

1981; Barr, 1986).

3.2 Water Quality Analytical Review

The water quality data obtained for the Site in 2015 were compared to historic data as well as

site specific water quality standards. The pertinent standards are described below:

Evaluation Criteria (EC) – The ECs are site specific post-removal performance criteria based upon MPCA derived performance limits.

Benchmark Value – The benchmark monitoring values are sector specific (F1, MN R050000) intervention limits listed in each National Pollutant Discharge Elimination System (NPDES) State Disposal System (SDS) permit.

The 2015 stabilization forms and analytical laboratory reports are included in Appendix B. A complete summary of current and historic analytical data is provided in Appendix C.


February 2016

3.2.1 Inorganic Results

3.2.1.1 Surface Water

May 2015 surface water analytical results were reported at concentrations below the

corresponding EC. Additionally, no sheen was observed at any of the surface water

monitoring points during the May sampling event.

3.2.1.2 Groundwater

Consistent with past sampling results, the EC for zinc was exceeded in monitoring well W-10

with total and dissolved concentrations of 160 µg/L and 120 µg/L, respectively. Zinc

concentrations reported for well W-10 have exceeded the corresponding EC of 86 µg/L since

April 2001. The laboratory analytical results have been compared to available National

Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment

Reconnaissance (HSSR) data (USGS, 2001) to determine potential background concentrations

of zinc in the groundwater. The median zinc concentration in the 799 wells sampled in the

Duluth 1o by 2o quadrangle during the NURE HSSR program was 113 g/L.

Monitoring well W8 also exhibited total and dissolved zinc concentrations above the EC with

a concentrations of 160 µg/L and 120 µg/L, respectively. However, elevated turbidity

appears to have contributed to the reported result as W-8 was pumped dry during well

stabilization inhibiting the collection of a low flow/low turbidity sample.

3.2.2 Organic Results

Water samples were collected and analyzed for PAHs during the 2015 sampling events

according to the parameters and methodologies illustrated in Table 1. A summary of current

and historic analytical data is provided in Appendix C.

3.2.2.1 Surface Water

May 2015 surface water analytical results at CP-1, CP-2, CP-3, CP-4, WM-1, and Seep-1 did

not contain PAHs at concentrations in excess of any corresponding ECs.

No indication of a sheen was observed at any monitoring point during the 2015 sampling

events.

3.2.2.2 Groundwater

No organic parameters were detected above the EC in 2015.


February 2016

3-3

3.2.3 Long Term Trends

The 2015 surface water and groundwater monitoring results were compared to historic data

and were found consistent with previous results. Constituent graphs have been included in

Appendix C for locations where a constituent has exceeded a corresponding EC during the

three most recent sampling events. This is limited to zinc at wells W-10 and W-8.

Additionally, the estimated total zinc concentration at W-8 is a relatively new maximum for

the sampling location. No other new maximum concentrations were detected during the May

or October 2015 sampling events.

3.2.4 Unexpected Results and Issues

Visual monitoring documented the occurrence of a sheen at the Wire Mill Pond and Tar

Between OU-I & J and tar bloom formation in Tar Between OU-I & J. Observations and

corrective actions are discussed in Section 4.3.

4.0 SITE INSPECTIONS

4.1 Monthly Site Inspections

AECOM monthly site inspections occurred between January 30 2015 and November 184,

2015. The Inspection Forms are included in Appendix D. Inspections were not hampered

by any site conditions. The inspection consisted of walking to each sampling point on the

Unnamed Creek (CP-1 through CP-4), walking the perimeter of the Wire Mill Pond, walking

the perimeter of OU-J, and walking several transects over the top of OU-J. Inspections

during a snow melt event and multiple rain events (i.e., greater than 0.25 inches) were

completed on March 31, 2015; May 16, 2015; and August 8, 2015.

4.1.1 Operable Unit-J and Unnamed Creek

The berm and cap at OU-J were observed in good condition throughout the 2015 monthly

inspections. The small disturbance observed approximately 15 feet south of the end of the

gabion baskets in 2009 and 2010 appeared unchanged.

Measured and observed flow at sampling points CP1, CP-2, and CP-3 were less than

observed in 2014 while CP-4 increased. Measured flow at CP-1 was 2.41 million gallons per

day (MGD) in May 2015 compared to 5.39 MGD in May of 2014. Similarly, calculated flow

at CP-2 was 6.42 MGD in May 2015 compared to 8.44 MGD in May 2014. Measured flow

at CP-4, however was 11.8 MGD in May 2015, greater than the 8.07 MGD measured in May

2014. Consistent with historical observations, flow at CP-3 was too low to measure. Flow

measurements are presented along with historical analytical data in Appendix C.

The presence of tar blooms was greater in 2015 than in 2014. Major tar blooms were

observed consistently from July through September 2015. The tar blooms observed are

attributed to significantly low water levels within the pond located between OU-I and OU-J

combined with warm ambient temperatures. The significantly low water levels appear to be

the result of 1) the removal of approximately 14 beaver dams along the Unnamed Creek, 2)

minimal stormwater run-off events, and 3) minimal recharge of the Unnamed Creek.

Between July and September 2015, AECOM recovered approximately 150 gallons in total of

tar-like substance. No sheen was observed at OU-L.

4.1.2 Wire Mill Pond

The inlet and outlet of the Wire Mill Pond were stable throughout 2015. Vegetation existed

around the entire perimeter with no apparent stressed areas. During the growing season, the

vegetation was active and appeared very healthy. The pond inlet and outlet were clear with a


February 2016

4-2

moderate flow. A light natural sheen and algae were observed at the Wire Mill Pond outfall

on May 15, 2015 and July 8, 2015. No observations of petroleum sheen were reported at the

Wire Mill Pond during 2015 monitoring.

4.1.3 Operable Unit K

No areas of erosion were observed at the OU-K cap in 2015. Additionally, no areas of

woody vegetation were identified within the limits of the OU-K cap. If necessary, an aquatic

safe herbicide will be applied to the OU-K cap in 2016 for ongoing maintenance. The last

application was in 2013.

4.2 Sheen and Tar Inspections

In 2007, MPCA requested the installation of absorbent booms at the Wire Mill Pond due to

the presence of petroleum sheen, and absorbent and containment booms at the pond north of

OU-J (Tar Between OU-I & J) due to the presence of sheen and tar-like substances. A work

plan including periodic inspections to document the presence of tar and/or sheen, condition

of booms, and recovery of tar was submitted on August 31, 2007 (USS, 2007). The work

plan was approved by MPCA on September 21, 2007 (MPCA, 2007). The current

configuration consists of 30 ft of absorbent boom at Tar Between OU-I & J; two 20 ft

absorbent booms, 20 ft of absorbent sweep, and a containment boom at the Wire Mill Pond

outfall; and 50 ft of absorbent boom at the west end of the Wire Mill Pond. Installation of

this configuration was performed on April 23, 2014, at the onset of spring thawing

conditions. Sheen and tar inspections, maintenance of the booms, and removal of any

recoverable tar continued throughout 2014 and 2015. The periodic USS/AECOM inspection

reports are included in Appendix D. A photographic log is presented as Appendix E. Tar

ball recovery and boom replacement activities as a result of inspection reports are discussed

below.

A containment boom, absorbent sock boom, and absorbent sweep were deployed at

the Wire Mill Pond inlet and outfall on March 31, 2015.

Absorbent sock booms were deployed at the Tar Between OU-I & J on April 3, 2015.

On July 17, 2015, all absorbent boom and sweep were replaced at the Tar Between

OU-I and OU-J and the Wire Mill Pond inlet and outfall.

On August 10, 2015, absorbent sweep was replaced at the Wire Mill Pond outfall.

On August 31, 2015, all absorbent boom and sweep were replaced at the Tar Between

OU-I and OU-J and the Wire Mill Pond inlet and outfall.


February 2016

4-3

As discussed in Section 4.1.1, increased tar bloom recovery was necessary in 2015

compared to recent years. Recoverable amounts of floating tar were observed at Tar

Between OU-I & J between July and September 2015.

A light sheen and algae were observed at the Wire Mill Pond outfall on May 15, 2015

and July 8, 2015.

The absorbent booms and sweeps at the Wire Mill Pond and at Tar Between OU-I & J

were removed on November 18, 2014 at the on-set of freezing conditions.

V:\Envir Mngt\Projects\USS Duluth\SWPPP\14 Inspection\Annual Reports 5-1

5.0 CONCLUSIONS AND RECOMMENDATIONS

The following conclusions can be drawn from the annual monitoring and inspection results:

1. Zinc concentrations reported for monitoring well W-10 (130 g/L total and

130 g/L dissolved) exceeded the corresponding EC for zinc during the May 2015

sampling event. Excluding the April 2000 sampling event, zinc concentrations at

monitoring well W-10 have exceeded the EC since 1994. However, when zinc

concentrations reported for well W-10 are compared to available National Uranium

Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment

Reconnaissance (HSSR) data (USGS, 2001), the W-10 zinc concentrations correlate to

the median zinc concentration (113 g/L) of 799 wells sampled in the Duluth 1o by 2o

quadrangle during the NURE HSSR program.

2. Zinc concentrations reported for monitoring well W-8 (160 g/L total and

120 g/L dissolved) exceeded the EC for zinc during the May 2015 sampling. This

concentration also reflects a new maximum zinc concentration for monitoring well

W-8, having only exceeded the EC once prior in 2014. However, elevated turbidity

appears to have contributed to the reported results both years as monitoring well W-8

was pumped dry during well stabilization, inhibiting the collection of a low flow/low

turbidity sample. Additionally, the geology at monitoring well W-8, logged during

installation as native reddish brown sandy clay, fat clay, and clayey sand, provides for

low hydraulic conductivity and well recharge. As stabilization activities using low-

flow methods (i.e., 50 mL/minute purge rate) at W-8 continue to result in an increase

in turbidity during sampling, future sampling events will involve passive sample

collection. Well W-8 will be purged dry and given approximately 24 hours to re-

charge prior to sampling. Care will be taken to minimize agitation of well water.

3. No changes in the OU-J cap were observed in 2015. Changes to the OU-J cap remain

those observed in 2007, including the slightly buckled gabion baskets and small

scarp. Continued inspections are recommended in 2016, focusing on the area with

buckled gabion baskets.

4. Presumably due to drought conditions during the summer of 2007, "blooms" of tar

balls occurred in the pond north of OU-J that required the installation of absorbent

booms, bi-weekly inspections by USS, and recovery of tar balls when feasible.

Throughout 2015, absorbent and containment booms were installed and replaced and


February 2016


recoverable tar blooms removed as needed, as determined by periodic inspections

conducted by USS. The containment and inspection efforts will continue into 2016.

Additionally, permanent response actions for this area are being assessed as part of

the Site Feasibility Study (GLLAP 2014).

5. Evaluation of 2015 surface water and groundwater data indicates that the monitoring

network at the facility has been adequate for the continued monitoring of surface

water and groundwater from the Site. Additionally, permanent response actions for

the Site are being assessed as part of the Site Feasibility Study (GLLAP 2014).

Narrative

CASE NARRATIVE

Client: URS Corporation

Project: Duluth SWPPP 2015

Report Number: 240-50556-1

With the exceptions noted as flags or footnotes, standard analytical protocols were followed in the analysis of the samples and no problems were encountered or anomalies observed. In addition all laboratory quality control samples were within established control

limits, with any exceptions noted below. Each sample was analyzed to achieve the lowest possible reporting limit within the constraints of the method. In some cases, due to interference or analytes present at high concentrations, samples were diluted. For diluted samples, the reporting limits are adjusted relative to the dilution required.

TestAmerica Canton attests to the validity of the laboratory data generated by TestAmerica facilities reported herein. All analyses performed by TestAmerica facilities were done using established laboratory SOPs that incorporate QA/QC procedures described in the application methods. TestAmerica’s operations groups have reviewed the data for compliance with the laboratory QA/QC plan, and data have been found to be compliant with laboratory protocols unless otherwise noted below.

The test results in this report meet all NELAP requirements for parameters for which accreditation is required or available. Any exceptions to NELAP requirements are noted in this report. Pursuant to NELAP, this report may not be reproduced, except in full, without the written approval of the laboratory.

Calculations are performed before rounding to avoid round-off errors in calculated results.

All holding times were met and proper preservation noted for the methods performed on these samples, unless otherwise detailed in the individual sections below.

All solid sample results are reported on an "as received" basis unless otherwise indicated by the presence of a % solids value in the method header.

This laboratory report is confidential and is intended for the sole use of TestAmerica and its client.

RECEIPT

The samples were received on 5/12/2015 9:30 AM; the samples arrived in good condition, properly preserved and, where required, on ice. The temperatures of the 2 coolers at receipt time were 4.5º C and 4.7º C.

SEMIVOLATILE ORGANIC COMPOUNDS (GCMS)

Samples CP-1 (240-50556-1), CP-3 (240-50556-2) and CP-4 (240-50556-3) were analyzed for semivolatile organic compounds (GCMS)

in accordance with EPA SW-846 Method 8270C. The samples were prepared on 05/13/2015 and analyzed on 05/18/2015.

Surrogates are added during the extraction process prior to dilution. When the sample is diluted, surrogate recoveries are diluted out and no corrective action is required.

No analytical or quality issues were noted, other than those described above or in the Definitions/Glossary page.

DISSOLVED LOW LEVEL MERCURYSamples CP-1 (240-50556-1), CP-3 (240-50556-2), CP-4 (240-50556-3) and TRIP BLANK (240-50556-4) were analyzed for dissolved

Low Level Mercury in accordance with EPA Method 1631E. The samples were prepared and analyzed on 05/20/2015.

Laboratory: TestAmerica Canton (Continued)

Samples CP-1 (240-50556-1), CP-3 (240-50556-2) and CP-4 (240-50556-3) were analyzed for total recoverable metals (ICP) in

accordance with EPA Method 200.7. The samples were prepared on 05/13/2015 and analyzed on 05/14/2015.

Method(s) 200.7 Rev 4.4: Some requested practical quantitation limits (PQLs) on the following samples fall below the laboratory's verified

standard quantitation limit: CP-1 (240-50556-1), CP-3 (240-50556-2) and CP-4 (240-50556-3)The continuing calibration blanks and method blanks may not support the lower PQL.

Runoff Inspection

Each year, at least one of your monthly inspections must be done when there is runoff from rain or snowmelt. Visually inspect the runoff for evidence of pollutants. For example, the runoff may have an oily sheen or be rusty, milky, muddy, etc.

Did you conduct a runoff inspection as part of today’s inspection? Yes No

Runoff was from: Snowmelt Rain

Describe the runoff (color, transparency, amount, etc.)

If evidence of pollutants is found, what changes will you make to clean up the runoff, and when will you make the changes?

Oil and grease runoff inspection (if applicable)

Certain industries must do at least two of their 12 monthly inspections when there is runoff from rain or snowmelt, and inspect the runoff for grease or oil sheens. One runoff inspection must be snowmelt.

Does your industry have to do two oil and grease runoff inspections annually? (See Part VII, Sector-specific requirements of the permit)

Yes (continue)

No (done with inspection)

Did you conduct a runoff inspection as part of today’s inspection? Yes (continue)
