Reference: Phase II Environmental Site Assessment Report, Howard University East Campus (Divinity School), 1400 Shepherd Street, NE, Washington, DC

Dear Mr. Love: ECS Mid-Atlantic, LLC (ECS) is pleased to present the following Phase II Environmental Site Assessment (ESA) report for the above-referenced site in Washington, DC.

PROJECT BACKGROUND The property consists of an approximately 22.51-acre parcel of land improved with the Howard University Divinity School including the Divinity Library, a vacant four-story historic building consisting of a library, offices, dormitories, a kitchen and cafeteria, a chapel, and a central courtyard. Additional improvements at the subject property include a two-story single family residence and a maintenance shed. Based on provided information, the property is being considered for redevelopment. ECS completed a Phase I ESA of the subject property in July 2018 (ECS Project Number 47:6230, dated July 2, 2018). The Phase I ESA identified the following Recognized Environmental Conditions (RECs) for the subject property:

The subject property was identified on the DC underground storage tank (UST) database as "HU - School of Divinity" addressed 1400 Shepherd Street, NE 14th & Shepherd Street, NE. The subject property was listed with three "Permanently Out of Use" USTs including one 1,000-gallon gasoline, one 4,000-gallon heating oil, and one 2,000-gallon heating oil UST. Additionally, one 550-gallon diesel UST with a "Currently In Use" status was listed at the subject property. ECS reviewed the DC Property Information Verification System (PIVS) for building department records. The PIVS included three construction/miscellaneous permits including permits for the removal of two 4,000-gallon underground storage tanks. The tank removal permit was dated March 7, 2005; however, no additional information related to the tank removal was available for review. Further, the Veeder Root tank monitoring system located in a mechanical room of the Divinity Library building did not appear to be operating during the site reconnaissance. Based on the potential for a petroleum release, the UST listing was considered a REC for the subject property.

Staining was observed on the dirt floor of the maintenance shed located on the central-eastern portion of the subject property. The staining was suspected to be related to vehicle and/or equipment repairs conducted in the maintenance shed. Containers of mechanical oils and degreasers were observed in the maintenance shed. The stained soil and suspected use of the maintenance shed for vehicle or equipment repairs was considered a recognized environmental condition (REC) for the subject property.

Additionally, the following Historical Recognized Environmental Condition (HREC) was identified:

The subject property was listed on the DC Leaking Underground Storage Tank (LUST) database as "Dr. Lynn Hamerling" addressed 1421 Taylor Street, NE. The subject property was listed with one closed LUST case which was opened in 1999 related to reports of heating oil in the sub-surface soil. The closed on-site LUST case was considered a HREC for the property.

The objective of this investigation was to collect soil and groundwater samples to assess whether the subsurface had been adversely impacted by previous on-site activities.

SCOPE OF WORK Utility Clearance ECS contracted a private utility locator to identify and mark the underground utilities in the work area (see boring location diagram included as Appendix I) on the property. The utilities were located on August 7, 2018. The proposed location of boring B-6 (according to the work plan) was not accessible due to dense vegetation. Therefore, boring B-6 was moved to the north in a more accessible area. Soil Borings On August 8, 2018, ECS employed a track-mounted Geoprobe to advance a total of six (6) soil borings across the site. The soil borings were drilled to depths ranging from approximately 17 to 27 feet below ground surface (bgs), at which point Geoprobe refusal was encountered. The Geoprobe used a hydraulic hammer to push a 2.5” diameter steel rod with a clear PVC sleeve into the ground in five-foot increments. The macrocore was then withdrawn from the ground and the sleeve removed, containing a relatively undisturbed soil core. The sleeve was cut open allowing examination of the entire soil core, and sampling of soil from the core. Soil was screened in 5-foot intervals throughout the depth of each boring. The soil was screened in the field with a Photoionization Detector (PID), which measures total volatile organic compounds (VOCs) emanating from the soil. While drilling the soil boring B-6, white to light gray sandy clay was encountered at a depth of 15 to 20 feet bgs, which was


saturated with free liquid petroleum product. Petroleum odors were noted in some of the other borings. However, free liquid petroleum product was only observed in the boring B-6. Temporary PVC wells were installed in borings B-5, B-6 and B-2 in order to collect groundwater samples. The wells consisted of ten feet of machine-slotted well screen topped with a solid PVC riser pipe to the surface.

SAMPLING METHODOLOGY Soil Sampling Based on field screening results, three soil samples from each boring were selected for laboratory analysis. During drilling activities, the PID malfunctioned and was not able to detect VOCs in the soil. Therefore, the soil samples were selected on the basis of visual and olfactory observations, such as staining and petroleum odors. When no evidence of petroleum impact was apparent in the soil cores, the soil samples were collected from (1) the top five feet of the borings, (2) immediately above the water table, and (3) the base of the boring. All selected soil samples were placed in laboratory grade glassware, packed on ice and submitted under chain-of-custody protocol to an independent laboratory for analysis of total petroleum hydrocarbons diesel-range and gasoline-range organics (TPH-DRO and TPH-GRO), polycyclic aromatic hydrocarbons (PAHs), volatile organic compounds (VOCs), and Resource Conservation and Recovery Act (RCRA) metals. Groundwater Sampling Saturated soil conditions indicative of groundwater were encountered in each of the six borings prior to termination of the borings at depths ranging from 10 feet to 15 feet bgs. ECS collected groundwater samples from three of the six borings (B-2, B-5 and B-6). The groundwater samples were collected with a peristaltic pump with dedicated tubing. The groundwater samples were placed into laboratory-grade bottles with appropriate preservative, packed on ice and submitted to an independent laboratory for analysis of TPH-DRO, TPH-GRO, PAHs, and VOCs. Temporary wells were removed after sampling. The borings were filled with bentonite clay according to the District Department of Energy and Environment (DOEE) guidelines.

RESULTS A total of six borings were advanced across the property. Obvious evidence of impact (i.e. PID readings, odors, staining, etc.) was observed in three of the six soil borings and free liquid petroleum product was observed in boring B-6. Detected soil contaminant concentrations were compared to the DC Risk Based Corrective Action (RBCA) Technical Guidance Tier 1, Table 5-9 Risk-Based Screening Levels (RBSLs) for a Resident Adult, in Sub-Surface Soil, for Indoor Inhalation. Additionally, detected concentrations of TPH GRO, TPH DRO, benzene, ethylbenzene, toluene, and xylenes were compared to the DC RBCA


Tier 0 screening level. Where the DC RBSLs were not established for certain compounds, the detected concentrations were compared with their respective EPA Regional Screening Level (RSL) for Resident Soil. The groundwater contaminant concentrations were compared to the DC RBCA Technical Guidance Tier 1, Table 5-9 Risk-Based Screening Levels (RBSLs) for a Resident Adult, in Groundwater, for Indoor Inhalation. Where the DC RBSLs were not established for certain compounds, the detected concentrations were compared with their respective EPA RSL for Maximum Contaminant Level (MCL). If the MCL was not established for certain compounds, the detected concentrations were compared with their respective EPA RSL for tapwater. The results are summarized below. The boring logs are included as Appendix II. The laboratory results are summarized in tables provided in Appendix III. A full laboratory report is provided in Appendix IV. Soil Sampling Results VOCs Thirteen VOCs were detected in one or more of the eighteen analyzed soil samples. Three samples had detectable concentrations above the Tier 1 screening levels.

Mercury was detected in seven of the eighteen samples at concentrations ranging from 0.08 mg/kg to 1.01 mg/kg. None of the concentrations exceeded the EPA RSL for resident soil of 11 mg/kg. Groundwater Sampling Results Groundwater samples were collected from boring B-2, B-5, and B-6. All three groundwater samples collected had detected concentrations of VOCs. VOCs A total of twelve VOCs were detected. The compounds which exceeded their respective screening levels are discussed below. tert-Amyl Alcohol (TAA) was detected at a concentration of 270 micrograms per liter (µg/L) in B-5 which exceeded the EPA RSL of 6.3 µg/L for tapwater. Benzene was detected at a concentration of 9.8 µg/L in B-2, 1,400 µg/L in B-5, and 927 µg/L in B-6, each of which exceeded the DC Tier 0 screening level of 5 ug/L. Additionally, the concentrations detected in B-5 and B-6 exceeded the DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 67.6 µg/L. Ethylbenzene was detected a concentration of 44.9 µg/L in B-2, 104 µg/L in B-5, and 3,540 µg/L in B-6. The detected concentrations in B-5 and B-6 exceeded the DC Tier 0 screening level of 70 ug/L. Additionally, the ethylbenzene concentration in B-6 exceeded the DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 206 µg/L. Naphthalene was detected at a concentration of 12.7 µg/L in B-2 and 614 µg/L in B-6. The detected naphthalene concentration in B-6 exceeded the DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 191 µg/L. Toluene was detected at a concentration of 188 µg/L in B-2, 1,580 µg/L in B-5, and 11,600 µg/L in B-6, each of which exceeded the DC Tier 0 screening level of 100 ug/L. However, none of the toluene concentrations exceeded the DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 90,000 µg/L. 1,2,4-Trimethylbenzene was detected at a concentration of 19.0 µg/L in B-2, 1,200 µg/L in B-5 and 2,770 µg/L in B-6. The detected concentrations in B-5 and B-6 exceeded its EPA RSL of 56 µg/L for tapwater.

The detected concentration B-6 exceeded its DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 191 µg/L. TPH DRO and TPH GRO TPH-DRO was detected in the groundwater samples from B-5 and B-6 at concentrations of 7.04 milligrams per liter (mg/L) and 87.7 mg/L, respectively. The TPH-DRO concentrations were below the DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 245 mg/L. TPH-GRO was detected in each of the three groundwater samples at a concentration of 1.35 mg/L in B-2, 39.8 mg/L in B-5 and 52.0 mg/L in B-6. The detected concentrations in B-5 and B-6 exceeded the DC Tier 1 RBSL for groundwater to indoor inhalation for a resident adult of 38.8 mg/L.

SUMMARY AND CONCLUSIONS In order to assess subsurface environmental conditions at the site, ECS advanced six borings across the site with a track-mounted Geoprobe to depths ranging between 17 to 27 feet bgs at which point refusal was encountered. Saturated conditions were observed in each of the six borings at depths ranging from 10 to 15 feet bgs. Three groundwater samples were collected from temporary wells. While drilling the soil boring B-6, white to light gray sandy clay was encountered and was saturated with free liquid petroleum product between a depth of 15 and 20 feet bgs. Petroleum odors were noted in some of the other borings. However, free liquid petroleum product was only observed in boring B-6. A total of 18 soil samples were submitted to an independent laboratory for analysis of TPH DRO, TPH GRO, VOCs, PAHs, and RCRA 8 Metals. Concentrations of VOCs including benzene, ethylbenzene, toluene, xylenes, and/or naphthalene exceeded their respective screening levels in three of the six samples collected from borings B-5 and B-6. Detected concentrations of PAHs were below their respective DC RBSLs or EPA RSLs; except for naphthalene which exceeded its DC Tier 1 RBSL for subsurface soil to indoor inhalation for a resident adult in the sample from boring B-6 collected at 20 feet bgs. TPH-DRO and TPH-GRO were detected in one of the soil samples exceeding its DC Tier 0 screening level and/or DC Tier 1 RBSL for subsurface soil to indoor


inhalation for a resident adult. None of the metals detected exceeded their respective EPA RSL for a resident adult, with the exception of arsenic. Both detected arsenic concentrations exceeded the EPA RSL for resident soil and were above typical background concentrations for this geologic area. In the event that petroleum-impacted material is excavated, it will need to be disposed of appropriately at a landfill or treatment/disposal facility permitted to accept such wastes. Disposal criteria for contaminated soil will depend on the jurisdiction in which it is to be disposed. In the District of Columbia, soils may be re-used on site if TPH-DRO and TPH-GRO concentrations are no greater than their applicable Tier 0 and/or Tier 1 screening levels, and individual constituent concentrations of BTEX are no greater than: 0.005 part per million (ppm) for benzene; 9.6 ppm for toluene; 0.04 ppm for ethylbenzene; and, 3.86 ppm for total xylenes. Soils that are excavated containing petroleum concentrations above these thresholds or below these thresholds that cannot be reused onsite, cannot be disposed of within the District limits and must be disposed of at an appropriate disposal or treatment facility. In Maryland, based on the Land Materials Administration Fact Sheet dated August 2017, soil containing petroleum (TPH DRO or TPH GRO) concentrations less than 230 mg/kg may be used as Category 1 fill materials at both residential and non-residential sites. Soil containing petroleum (TPH DRO or TPH GRO) concentrations less than 620 mg/kg may be used as Category 2 fill materials on non-residential sites only. Soils containing petroleum concentrations greater than 620 mg/kg will need to be disposed at a licensed disposal/treatment facility capable of accepting the material. However, each of the other detected contaminants will also need to be below their respective residential or commercial screening level for use as Category 1 or 2 fill material. In Virginia, solid waste management regulations divide petroleum-impacted soils into various classes depending on concentration. Soils containing petroleum concentrations less than 50 mg/kg and total BTEX less than 10 mg/kg may be disposed with certain restrictions (see 9VAC20-81-660-D.2.d). Soils containing less than 500 mg/kg petroleum may be disposed of in a lined landfill permitted to receive such wastes. Soils containing petroleum concentrations greater than 500 mg/kg may not be disposed of in Virginia landfills, unless the permit expressly allows for such disposal. In practice, it is often difficult for developers and contractors to find a suitable disposal location for the “marginally-impacted” petroleum contaminated soils- i.e. soils containing detectable petroleum concentrations below the regulatory thresholds. This is due to the paucity of net fill construction sites in the area, and the relative abundance of legitimately clean fill materials with no petroleum contamination. Given the option, the developers of most fill sites will prefer clean fill materials over marginally-impacted materials. Consequently, it is common practice in this region to dispose of even low-level contaminated soils at petroleum-impacted soil facilities such as Clean Earth, Inc. of Greater Washington (Upper Marlboro, Maryland) or Soil Safe, Inc. (Brandywine, Maryland).


Detected groundwater concentrations of VOCs including benzene, ethylbenzene, naphthalene, toluene, xylenes, 1,2,4-trimethylbenzene, 1,3,5-trimethylbenzene and TAA, PAHs including 2-methylnaphthalene and naphthalene, TPH-DRO, and TPH-GRO exceeded their respective DC RBSLs or EPA RSLs. The property and surrounding areas are supplied with public water. Therefore, the primary risk pathway for exposure is from volatilization of subsurface contamination to indoor air. In the event contamination exceeding risk-based thresholds is left in place, ECS recommends that a vapor barrier be constructed beneath future buildings constructed. If the existing building will remain, ECS recommends soil vapor sampling to determine if the subsurface contamination poses an unacceptable vapor risk for the current building. If future redevelopment will result in groundwater dewatering during construction activities, A National Pollutant Discharge Elimination System (NPDES) permit from EPA and approval from DOEE will need to be obtained prior to discharge of the groundwater to the municipal separate storm sewer system (MS4). Additional groundwater characterization would be necessary in order to obtain DOEE approval to discharge. Based on the sampling results, it is possible that treatment of the groundwater would be necessary prior to discharge to the MS4. Based on the soil and groundwater analytical results, it is ECS’s opinion that the detected contaminant concentrations in soil and groundwater could pose an unacceptable risk to the environment and human health. The presence of free petroleum product in boring B-6 is a condition that ECS is obligated to report to the DOEE, as are the exceedances of the Tier 0 and Tier 1 Screening Levels identified for certain soil and groundwater samples. DOEE will likely open a Leaking Underground Storage Tank (LUST) case for the property as a result of the findings. Based on our experience with similar projects in the District of Columbia, additional investigation and remediation will be required before the case will be closed. While we do not know exactly what DOEE will require, it is ECS’s opinion that the additional work required for the site will include the installation of additional soil borings to assess the horizontal extent of the soil contamination, the removal of USTs and contaminated soil in the area of SB-5 and SB-6 (the maintenance shed area as discussed in the Phase I ESA), and the installation of down-gradient monitoring wells to assess the potential for off-site migration of contaminants. Additional remedial activities may be required by DOEE.
