(NOVA) was retained by LR Statesville Investors, LLC (Client) to complete an Environmental Site Assessment Work Plan (Work Plan) on the Statesville Avenue Properties site located at 3239, 3245 Statesville Avenue and 2128, 2129 Whittington Street in Charlotte, Mecklenburg County, North Carolina (Subject Property). A site location map is included as Figure 1 in the Attachments. 1.1 SITE AND PROJECT INFORMATION The Subject Property consists of an approximately 19.7-acre site located at 3245 Statesville Avenue in Charlotte, Mecklenburg County, North Carolina. According to the Mecklenburg County Geographic Information System (GIS) database, the Subject Property consists of five (5) land parcels identified as Mecklenburg County Parcel IDs 07706303, 07706308, 07706309, 07706313, and 07705201. The Subject Property is bordered by Statesville Avenue to the east, Atando Avenue and Irwin Creek to the south, and Interstate 77 and Kennedy Branch to the west. A Site Map including an aerial photograph is included as Figure 2 in the Attachments. The Subject Property is currently undeveloped, partially wooded, vacant land. The Subject Property also contains greenspace including trees, grass, and low-growing vegetation. Irwin Creek extends through the southeast, wooded corner of the Subject Property in a generally east-west orientation. 1.2 HISTORICAL SUMMARY OF SITE ACTIVITIES The Subject Property is located on the north side of Charlotte, North Carolina. Contaminants had not yet been identified at the Subject Property at the time of the Brownfields Property Application Submittal (NCBP# 26028-22-060) on January 6, 2023, by Alexander Ricks, PLLC on behalf of LR Statesville Investors, LLC (Prospective Developer). The Brownfields Property Application summarized the historical uses of the Subject Property as "residential, wooded land, and agricultural/pastureland starting at least in 1938. In the 1970s, one residential structure was removed. In the 2000s, the remaining residential structures were removed and the property became increasingly wooded/vegetated land.” ECS Southeast, LLP (ECS) performed a Phase I ESA report for the Subject Property, dated July 20, 2022. The Phase I ESA identified the following off-site Recognized Environmental Conditions (REC) in connection with the Subject Property: Environmental Site Assessment Work Plan May 1, 2023 Statesville Avenue Properties NOVA Project Number 10704-3023003 Page 2 Off-site RECs: • “Based on the close proximity to the subject property, as well as documented impacts above standards near Irwin Creek at the former landfill facility, there is a potential for former waste discharge and runoff to Irwin Creek from this facility to impact the subject property. Based on this information, ECS considers the potential for the former east adjacent landfill to impact the subject property to represent a REC. • Based on the length of operation as a gas station (at least 10 years), distance to the subject property, and lack of UST closure documents, ECS considers the potential for the former gas station at 3100 Statesville Avenue to impact the subject property to represent a REC. • ECS considers the potential for the upgradient, former east adjacent/adjoining auto repair facilities (3300/3304 and 3307 Statesville Avenue) to impact the subject property represents a REC.” PREVIOUS ASSESSMENT NOVA reviewed a Report of Environmental Assessment Services prepared by ECS Southeast, LLP (ECS), dated January 12, 2023, that included methane screening, groundwater sampling, soil gas sampling, soil sampling and stockpile soil sampling. The following analytical results provided below are from this January 12, 2023 report. METHANE SCREENING RESULTS ECS installed eight (8) methane screening points (M-1 through M-8) within the approximate proposed building footprints on June 13, 2022. ECS collected methane gas measurements on November 14 and 15, 2022 including the measurement of methane, carbon dioxide, oxygen and hydrogen sulfide concentrations present (if any) and the static and differential pressures utilizing a Landtec GEM 5000 Pls Landfill Gas Analyzer and Extraction Monitor. Screening point M-1 was previously damaged and was unable to be used during the November 2022 sampling event. Methane was not detected in the seven (7) points screened (M-2 through M-8) on November 14 and 15, 2022. Based on these findings, NC DEQ confirmed via email correspondence on March 30th, 2023 that no further methane screening or methane mitigation is required at this time. Environmental Site Assessment Work Plan May 1, 2023 Statesville Avenue Properties NOVA Project Number 10704-3023003 Page 3 GROUNDWATER ANALYTICAL RESULTS ECS installed five (5) monitoring wells (MW-1 through MW-5) on November 15 and 16, 2022 to depths ranging from 15 to 24 feet below ground surface (bgs). The monitoring wells were reportedly “developed until the water produced was visibly free of sediment”. ECS used a low-flow peristaltic pump to collect groundwater samples on November 18, 2022 after the monitoring wells had 24-hours to stabilize. Six (6) groundwater samples (including MW-Dup) were collected and analyzed for Volatile Organic Compounds (VOCs), Semi-Volatile Organic Compounds (SVOCs) and dissolved RCRA Metals. VOCs: Acetone was detected in groundwater samples MW-3 and MW-4, 2-butanone was detected in groundwater sample MW-3 and methyl tert-butyl ether (MTBE) was detected in MW-1 and MW-2 at concentrations above laboratory method detection limits, but below North Carolina 2L Groundwater Quality Standards and Vapor Intrusion Screening Levels (VISLs), if applicable. No additional VOCs were detected above their respective lab method detection limits. SVOCS: No SVOCs were detected above their respective laboratory method detection limits. Metals: Total barium in MW-2, MW-3 and MW-5 samples, total chromium in MW-2, MW-3, MW-4 and MW-5 samples, and total lead in MW-2, MW-3 and MW-5 samples were detected at concentrations greater than their respective NC 2L Groundwater Quality Standards. Dissolved chromium in MW-3 and dissolved lead in MW-3 and W-4 were detected at concentrations greater than their respective NC 2L Groundwater Quality Standards. SOIL GAS ANALYTICAL RESULTS Eight (8) shallow soil gas probes (SG-1 through SG-8) were advanced to depths of 6 feet bgs utilized a Direct Push Technology (DPT) drill rig. The soil gas vapor points were developed with dedicated Nylaflow tubing, air stone, 1’ of clean coarse sand and a bentonite seal. The soil gas probes were purged three (3) volumes of tubing with a seal test performed using helium gas tracer. No soil gas samples were collected from SG-7 and SG-8 as water was observed in tubing during the development of these vapor points. Seven (7) soil gas samples (including duplicate SG-Dup) were collected via a 1-liter Summa canister and analyzed for VOCs via EPA Method TO-15. Benzene in SG-1 and 1,3-butadiene in SG-1 and SG-5 were detected in exceedance of their respective Residential VISLs but below their respective Non-Residential VISLs. Environmental Site Assessment Work Plan May 1, 2023 Statesville Avenue Properties NOVA Project Number 10704-3023003 Page 4 The soil gas analytical results were entered into NC DEQ’s Risk Calculator based on four (4) exposure units (buildings #1 through #4) based on the proposed building layout. The highest concentration detected for each compound within each exposure unit was entered into the risk calculator as the hypothetical “worst case scenario” for that proposed building. The soil gas concentrations detected in proposed buildings #1, 2 and 3 did not exceed the risk threshold for Residential or Non-Residential usage based on the risk calculator. The concentrations detected in proposed building #4 exceeded the risk threshold for Residential usage but not for Non-Residential usage based on the risk calculations. ECS re-ran the risk calculations for building #4 excluding the concentration of 1,3-Butadiene, “as this compound is most likely associated with the installation of the soil gas probes (due to heating and degradation of rubber O-rings in drive rods) and not normally indicative of subsurface conditions”. The revised building #4 risk calculator results did not exceed Residential or Non- Residential thresholds and the re-calculated Hazard Index was reduced from 3.3 to 0.046 when excluding the 1,3-Butadiene concentration. SOIL SAMPLE RESULTS ECS collected nine (9) soil samples (SB-1 through SB-8 including one (1) duplicate) during the installation of the eight (8) soil gas sample points within the approximate proposed building footprints. The soil samples were screened with a Photo-Ionization Detector (PID) in the field and soil samples yielding the highest PID readings were collected and sent for laboratory analysis for VOCs, SVOCs, RCRA 8 Metals and hexavalent chromium. Methylene chloride was detected in soil borings SB-2, SB-4, SB-5, SB-6 and SB-8 (at varying depths) at concentrations greater than the Protection of Groundwater Preliminary Soil Remediation Goal (PSRG). Additional VOCs were detected above the laboratory method detection limits but below their respective PSRGs. Benzo(a)anthracene, benzo(a)pyrene and benzo(b)fluoranthene were detected in the building #1 composite sample at concentrations greater than their respective Residential and Protection of Groundwater PSRGs. Benzo(b)fluoranthene was detected in the building #2 composite sample at a concentration greater than its Residential and Protection of Groundwater PSRGs. Hexavalent chromium was detected in exceedance of the Residential PSRG in building #1, #2 and #4 composite samples. Additional metals were detected at concentrations above the laboratory method detection limits but below their respective PSRGs. Environmental Site Assessment Work Plan May 1, 2023 Statesville Avenue Properties NOVA Project Number 10704-3023003 Page 5 STOCKPILE SOIL SAMPLE RESULTS ECS collected three (3) composite soil samples (SP-1, SP-2 and SP-3) and three (3) grab samples from the approximate 3,000-cubic yard stockpile in the western portion of the Subject Property. The soil stockpile was divided into three (3) sections and five (5) soil samples were collected to a depth of 15 feet bgs using DPT within each section. In addition, individual grab samples for VOC analysis were collected from sample intervals with the highest photoionization detector (PID) readings. The three (3) composite soil samples were analyzed for SVOCs and RCRA 8 Metals (plus hexavalent chromium) and five (5) individual grab soil samples were analyzed for VOCs. Methylene Chloride was detected in individual soil sample SS-4 (0-5’) at a concentration greater than the Protection of Groundwater PSRG. Totally xylenes detected in SS-4 (0-5’) were detected above laboratory method reporting limits but less than PSRGs. No SVOCs were detected above the laboratory method reporting limits. Hexavalent Chromium was detected in each the of the composite stockpile soil samples (SP-1, SP-2, and SP-3) at concentrations greater than its Residential PSRG but less than the Protection of Groundwater PSRG. Additional metals were detected above laboratory method reporting limits but below their respective PSRGs. 1.3 DATA GAPS Based on correspondence with NC DEQ (temporary) Brownfields Project Manager Ms. Carolyn Minnich on March 30, 2023 after her review of the findings of the previous methane screening, soil, soil gas and groundwater sampling performed by ECS as summarized in their Report of Environmental Services dated January 12, 2023, it has been determined that sediment soil and surface water sampling from Irwin Creek will be required in order to complete a Brownfields Agreement for the Subject Property. NC DEQ also requested the completion of an NC Brownfields Receptor Survey. NOVA’s Work Plan was designed to assess the current conditions at the Subject Property. The Work Plan addresses one (1) main area associated with the Subject Property. The proposed sediment and surface water samples are intended to assess the upstream and downstream conditions of Irwin Creek as it pertains to the Subject Property. NOVA has developed this Work Plan to assess sediment and surface water conditions in Irwin Creek on the Subject Property. NOVA will collect sediment and surface water from upstream and downstream locations of Irwin Creek within the boundary of the Subject Property. The upstream and downstream sample locations are intended to assess if the conditions of Irwin Creek are being negatively impacted by the Subject Property or off-site sources. Environmental Site Assessment Work Plan May 1, 2023 Statesville Avenue Properties NOVA Project Number 10704-3023003 Page 6 2.0 SCOPE OF WORK NOVA will be completing site activities in Irwin Creek along the boundary of the Subject Property. A Site Map is provided as Figure 2 in the Attachments identifying the sampling locations. The details of each sampling location are summarized on Table 1 in the Attachments. 2.1 SEDIMENT SAMPLING Based on the potential for impact to Irwin Creek, the identified RECs and to satisfy NC DEQ’s request for additional data, NOVA proposes to collect two (2) sediment samples from upstream and downstream locations of Irwin Creek via grab sampling. The sediment samples will be collected at a shallow depth of approximately 0-1 feet below the surface of the creek bed. One (1) sediment sample from each location will be submitted to an appropriately accredited laboratory for the following analyses: • Volatile Organic Compounds (VOCs) by United States Environmental Protection Agency (US EPA) Solid Waste (SW)-846 Method 8260, • Semi-Volatile Organic Compounds (SVOCs) by USEPA SW-846 Method 8270, • Resource Conservation and Recovery Act (RCRA) Metals by USEPA SW-846 Method 6010 and 7473, and • Hexavalent Chromium by USEPA SW-846 Method 7199. 2.2 SURFACE WATER SAMPLING NOVA proposes to collect two (2) surface water samples, one (1) each from upstream and downstream locations of Irwin Creek along the southern boundary of the Subject Property. The surface water samples will be co-located with the sediment samples. The collected surface water samples will be submitted to an appropriately accredited laboratory for the following analyses: • VOCs by USEPA SW-846 Method 8260, • SVOCs by USEPA SW-846 Method 8270, and • RCRA Metals by SW-846 Methods 6010/7473.
