A site location map is included as Figure 1 in Appendix A. 1.1 SITE AND PROJECT INFORMATION The Subject Property is located at 305 Doggett Street and 242/306 West Tremont Avenue in Charlotte, Mecklenburg County, North Carolina. According to the Mecklenburg County Geographic Information System (GIS) database, the Subject Property measures approximately 2.441-acres and contains three (3) tax parcels identified by Parcel Numbers 12103314 (305 Doggett Street), 12103307 (242 West Tremont Avenue) and 12103306 (306 West Tremont Avenue). The Subject Property is bordered by Doggett Street on the north, West Tremont Avenue on the south, an unnamed alley on the west, and by other developed properties to the east. A Site Map including an aerial photograph is included as Figures 2 in the Attachments. The Subject Property is currently developed with following structures: 305 Doggett Street – This address contains three (3) buildings according to property tax records. • Building 1: 1-story warehouse building including 10,200 total square feet, built in 1954; • Building 2: 2-story light-manufacturing building including 27,024 total square feet, built in 1963; and, • Building 3: 1-story warehouse building including 600 total square feet, built in 1981. 306 West Tremont Ave – This address contains one (1) 2-story warehouse building including 11,644 total square feet, built in 1964. The structure is attached to a 2-story office building with canopy structures located between and is referred to as the “accounting” building. 242 West Tremont Ave – This address contains one (1) 1-story light manufacturing building including 10,370 total square feet, built in 1950. This building is referred to as the “Dilworth” building and is divided into the air heater production line with two loading bays in the western portion with warehouse storage in the eastern portion. Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 2 The Subject Property contains associated asphalt-paved parking to the north, east and south of the office and manufacturing structures. The site also contains greenspace including trees, grass, and low-growing vegetation. A Phase I Limited Site Assessment Report, conducted by Altura Environmental, Inc. (Altura), on Gas-Fired Products, Inc., at 306 West Tremont Avenue, Charlotte, North Carolina was conducted on October 6, 2003. The document indicated that the Phase I Limited Site Assessment (LSA) was performed in accordance with NCDENR (former name for NCDEQ) guidance. Additional site history was provided in the LSA and stated that “the subject property was formerly occupied by J.B. Thomas and Sons, a general contracting firm, in the late 1940’s and early 1950’s. It is believed that the former UST was installed by J.B. Thomas and Sons, and the last use of the UST was during that time. There are no other USTs reported to be present on the subject site.” On August 22, 2003, Altura was onsite to drill one (1) soil boring, collect soil samples, install one (1) groundwater monitoring well and collect a groundwater sample from said well. Soil samples were collected at depths of -13’, -17’ and -22’ below ground surface (bgs) from the soil boring drilled within the UST source area. Partially weathered rock was encountered at -24’ below ground surface. The soil samples were analyzed for Volatile Organic Constituents (VOCs), Methyl tert-Butyl Ether (MTBE), Isopropyl Ether (IPE), Semi-VOCs (SVOCs), volatile petroleum hydrocarbons and extractable petroleum hydrocarbons in accordance with NCDENR guidelines. The analytical results of soil samples collected in the source area during the Phase I LSA indicated that no petroleum constituents were detected at concentrations in excess of NCDENR soil to groundwater maximum soil contaminant concentrations, which are the most stringent limits established by NCDENR. A groundwater monitoring well was installed with slotted screening from 19 to 24 feet bgs as groundwater was recorded at approximately 18.5 feet. The groundwater sample was analyzed in accordance with NCDENR guidelines for heating oil and included EPA Method 602 plus xylenes, EPA Method 625, and volatile petroleum and extractable petroleum hydrocarbons by MADEP VPH and EPH, respectively. The groundwater laboratory analysis indicated that several petroleum constituents were detected in the groundwater at concentrations in excess of the 2L or interim Standard and in excess of 10x the 2L or Interim standard. However, none of the concentrations were detected in excess of the listed Gross Contaminant Levels (GCLs). Based on the findings of the LSA, Altura recommended that “based on the land use information provided in this report for the subject site and surrounding properties, it is the opinion of Altura that the property be designated an industrial/commercial property. All petroleum constituents identified in the soil samples collected from the source area boring were detected at concentrations below the NCDENR soil to groundwater maximum soil concentrations values. In addition, the analytical results of the groundwater sample collected from monitoring well MW-1 indicate that none of the Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 3 required parameters were detected at concentrations in excess of the listed GCLs. As a results, a Notice of Residual Petroleum (NRP) has been completed for the subject site and recorded at the Mecklenburg County Register of Deeds Office…Altura requests that the NCDENR issue a “No Further Action” letter for the subject site.” A UST Closure and Assessment Report was conducted by Altura for Gas-Fired Products, Inc., dated December 8, 2003. The UST closure report indicated that NCDENR provided closure for UST release incident pending recordation of a Notice of Residual Petroleum (NRP) at the Mecklenburg County Register of Deeds Office. The NRP placed a perpetual land use restriction on the property. Due to the soil impact above the residential MSCCs, the perpetual land use restriction states that, “the site shall be used for industrial/commercial use only. The perpetual land use restriction, as it pertains to the groundwater, states that, “groundwater from the site is prohibited from use as a water supply. Water supply wells of any kind shall not be installed or operated on the site.” Altura stated that, based on conversations with NCDENR, if impacted soils are removed from the site such that confirmatory soil sampling indicated petroleum concentrations are below the residential MSCCs, then the perpetual land use restriction pertaining to the site soils can be removed from the deed restriction. In Altura’s opinion “if the site building was razed providing easy access to subsurface soils, that the impacted soils could be removed from the former UST area, confirmatory soil samples could be collected (showing results that are below the residential MSCCs), and the soil restriction could be removed from the property deed. Hart & Hickman, PC (H&H) performed soil vapor assessment activities documented in a Subslab Soil Vapor Sampling Report for Gas Fired Products Facility dated February 18, 2013. The subslab soil vapor sampling was conducted to evaluate the potential for vapor intrusion into site buildings consistent with Brownfields program requirements should the site enter the Brownfields program in the future. On November 8, 2012, H&H conducted subslab soil vapor sampling from six (6) locations within the manufacturing, office and warehouse areas of the Subject Property. H&H utilized six-liter Summa canisters to collect the vapor samples as they were submitted for laboratory analysis for volatile organic compounds (VOCs) by EPA Method TO-15 and for helium by EPA Method 3C. H&H stated “Low concentrations of multiple VOCs were detected in the six samples collected. The concentrations were compared to NCDENR Inactive Hazardous Sites Branch (IHSB) Industrial/Commercial Soil Vapor Screening Levels. The ISHB screening levels are based upon conservative assumptions. None of the detected compound concentrations exceeded their IHSB Industrial/Commercial Soil Vapor Screening Levels. In accordance with DENR Brownfields program guidance and H&H’s professional experience with the Brownfields program, because the subslab soil vapor Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 4 samples concentrations were less than the applicable screening levels, H&H does not recommend further evaluation of the vapor intrusion pathway such as indoor air sampling or indoor air mitigation.” H&H performed a Phase I ESA Report for Dilworth Mattress Factory, 242 West Tremont Avenue, Charlotte North Carolina, dated June 29, 2016. The Phase I ESA indicated that the 0.43-acre land parcel was occupied by Dilworth Mattress Factory, a mattress manufacturer, at the time of the Phase I ESA. The site was developed with the eastern portion of the current site building in 1950 as the western portion of the site building was developed in 1984. The site has reportedly operated as a mattress manufacturer since it was constructed in 1950. H&H identified the following off-site issues resulting in Recognized Environmental Conditions (RECs) in connection with the Subject Property: • “Virginia Carolina Chemical (VCC) Charlotte (249 Tremont Avenue) is located adjacent to the south and southwest across Tremont Avenue and upgradient to cross-gradient from the site. According to reports reviewed, this facility formerly operated as a phosphate fertilizer plant from at least the 1890s until the 1930s. An adjacent plant to the east also operated as a cottonseed oil plant. The facility occupied the property until 1974 at which time the current commercial and light industrial buildings were developed. Soil at the facility is impacted by arsenic and lead as a result of the former activities and ExxonMobil is identified as the responsible party for the cleanup. ExxonMobil has removed source area soil from feasible locations at the facility and currently maintains a cap on the property. Results of soil assessment indicated that metals were not detected above screening levels in the samples located closest to the subject site and therefore the potential for soil impact to the site from the VCC facility appears low. Recent groundwater sampling events indicate the presence of low levels of lead, arsenic, tetrachloroethene (PCE), and trichloroethene (TCE) in groundwater at this facility above NC groundwater standards in monitoring wells located close to the site. Concentrations of PCE (0.91 micrograms per liter (μg/l) versus standard of 0.7 μg/l) and TCE (4.2 μg/l versus standard of 3 μg/l) were detected in the wells closest to the site.” • “South Boulevard Properties, Inc./Atherton Mill Property/Flakt Inc. Bahnson/Parks- Cramer Company (2000-2140 South Boulevard) is located approximately 1,200 feet to the east and topographically upgradient of the site. According to records reviewed, in 1962, the Parks-Cramer facility began to operate a vapor degreasing unit for cleaning and preparation of metal parts prior to paint application in the main Parks-Cramer building north of the site. Initially trichloroethene (TCE) was used as the solvent in the degreasing process, which was replaced with 1,1,1,- trichloroethane (1,1,1-TCA) from 1976 to 1988. Releases of solvents occurred Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 5 beneath the vapor degreaser and discharged through a stormwater system to the adjacent Norfolk Southern railroad tracks west of the parent parcel. Releases of volatile organic compounds also occurred through spraying of waste solvents for weed control along an earthen embankment from 1962 to 1979. Results of groundwater assessment indicate that groundwater impacts (TCE was detected as high as 200,000 μg/l at this property) have migrated to the west-northwest toward downgradient properties including the subject site. Results of analysis of groundwater samples collected approximately 400 ft southeast and upgradient of the site indicated the presence of TCE at greater than 5,000 μg/l. Interim soil remediation was conducted in the late 1980s, and groundwater remediation using a pump and treat system occurred from 1990 to 2001. The North Carolina Department of Environmental Quality (DEQ) Hazardous Waste Section (HWS) formerly regulated the Parks-Cramer release incident. On January 19, 2006, the HWS ceased regulation pursuant to a risk assessment and technical impracticability determination. The determination was primarily based on: 1) the inability to continue groundwater extraction due to a county-wide moratorium on discharge of treated groundwater to the sanitary system, 2) the inadequacy of available technologies to address removal or in situ destruction of chlorinated volatile organic compounds present as dense non-aqueous phase liquids in bedrock, 3) the adoption of a county-wide well ordinance to ensure receptor protection, 4) the lack of predicted impact to the ultimate surface water receptors, and 5) the costs associated with continuation of remedial efforts. This facility is cited as the source area for chlorinated solvent impacts to the groundwater in the area near the site. In addition, according to groundwater model predictions of the chlorinated solvent groundwater contamination plume, the subject site is predicted to be impacted from the release at this facility.” • “2000 Hawkins Street (2000 Hawkins Street) is located approximately 350 feet to the east and topographically cross-gradient of the site. According to the reports reviewed, the groundwater samples collected from the wells on the property indicated the presence of chlorinated solvent compounds, phthalates, methyl-tert- butyl ether (MTBE), and benzene in groundwater above North Carolina groundwater standards. The highest compound concentrations were detected in the upgradient sample in the eastern portion of the facility which had a concentration of the chlorinated solvent TCE at 6,200 μg/l (versus the NC groundwater standard of 3 μg/l). The sample collected closest to the subject site contained TCE at a concentration of 41 μg/l.” H&H identified a potential environmental concern in connection with the Subject Property as a heating oil AST was observed on the northern exterior wall of the western portion of the site building. The AST is no longer utilized. No indications of releases were observed in associate with the AST. H&H did not consider it to be evidence of a REC. No recommendations were noted in the Phase I ESA. Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 6 NOVA Engineering & Environmental, Inc. performed a Phase I ESA for the Doggett Street & West Tremont Avenue Site dated September 17, 2020. NOVA identified the following on-site issue resulting in Recognized Environmental Conditions (RECs) in connection with the Subject Property: • The impacts to soil and groundwater identified above applicable regulatory thresholds during NOVA’s 2020 Limited Phase II ESA. Additionally, NOVA identified the following on-site and off-site issues resulting in Controlled Recognized Environmental Conditions (CRECs) in connection with the Subject Property: ON-SITE • The former presence of a 300-gallon heating oil UST and associated residual petroleum at the Subject Property. OFF-SITE • The Carolina Foundry facility located adjoining to the east and south of the Subject Property. • The Kale Bindex, Inc/2000 Hawkins Street facility located adjoining to the east of the Subject Property. • The Virginia Carolina Chemical (VCC)/ExxonMobil Oil Corp 99CLT facility located adjoining to the south of the Subject Property. NOVA Engineering & Environmental, Inc. performed a Limited Phase II ESA for the Doggett Street & West Tremont Avenue Site dated September 17, 2020. The following is a summary of the findings of NOVA’s Limited Phase II ESA: VOC CONSTITUENTS IN SOIL Bromomethane, Chloromethane, and Naphthalene were detected in a soil sample collected on the northeastern portion of the Subject Property (S-2) at concentrations above their NC DEQ Protection of Groundwater PSRGs. Naphthalene was detected in soil sample S-2 at a concentration above its residential PSRG. The remaining VOC constituents detected in soil were at concentrations below NC DEQ Preliminary Soil Remediation Goals (PSRGs). Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 7 SVOC CONSTITUENTS IN SOIL 1-Methylnaphthalene, 2-Methylnaphthalene, Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Dibenzo(a,h)anthracene, Indeno(1,2,3-cd)pyrene, and Naphthalene were detected in soil sample S-2 at concentrations above their NC DEQ Protection of Groundwater PSRGs. Benzo(a)anthracene, Benzo(a)pyrene, Benzo(b)fluoranthene, Dibenzo(a,h)anthracene, Indeno(1,2,3-cd)pyrene, and Naphthalene were detected in soil sample S-2 at concentrations above their residential PSRGs. Benzo(a)pyrene was detected in soil sample S-2 at a concentration above its industrial/commercial PSRG. The remaining SVOC constituents detected in soil were at concentrations below NC DEQ PSRGs. METALS CONSTITUENTS IN SOIL Arsenic was detected in the five (5) soil samples collected on the northeastern portion of the Subject Property (S-1 through S-5) at concentrations above the NC DEQ residential PSRG of 0.68 mg/kg and the NC DEQ industrial/commercial PSRG of 3.0 mg/kg. However, the detected concentrations of Arsenic are below the mean concentration reported to be naturally occurring in the eastern conterminous United States based on the observed background concentrations in Element Concentrations in Soils and Other Surface Materials of the Conterminous United States, Hansford T. Shacklette and Josephine G. Boerngen, United States Geological Survey, 1984. Total Chromium was detected in soil samples S-1 through S-5 at concentrations above the most stringent NC DEQ PSRGs for Hexavalent Chromium. However, there have been no known or suspected historical source of Hexavalent Chromium at the Subject Property. Consequently, the less stringent Trivalent Chromium PSRGs have been used for the purposes of this report. The remaining detections of metals in soil were at concentrations below the NC DEQ PRSGs. VOC CONSTITUENTS IN GROUNDWATER Naphthalene, Tetrachloroethylene (PCE) and Trichloroethylene (TCE) were detected in a groundwater sample collected on the northeastern portion of the Subject Property (S-2) above their NC DEQ 15A NCAC 02L .0202 Groundwater Standards. Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 8 The remaining VOC constituents detected in groundwater were at concentrations below NC DEQ 15A NCAC 02L .0202 Groundwater Standards. SVOC CONSTITUENTS IN GROUNDWATER The SVOC constituents detected in groundwater were at concentrations below NC DEQ 15A NCAC 02L .0202 Groundwater Standards. METALS CONSTTIUENTS IN GROUNDWATER The Chromium detected in groundwater sample collected on the southwestern portion of the Subject Property (S-4) was at a concentration above its NC DEQ 15A NCAC 02L .0202 Groundwater Standard. The remaining metals constituents detected in groundwater were at concentrations below NC DEQ 15A NCAC 02L .0202 Groundwater Standards. Chromium occur naturally in Piedmont geology soils. Consequently, NOVA believes that the concentrations of metals detected in the groundwater are likely associated with excess sediment/background concentrations in the collected groundwater and are not due to the historic operations on the Subject Property. Based on the findings of the previous assessments and NOVA’s Phase I and Limited Phase II ESAs, the Subject Property was entered into the NC DEQ Brownfields Programs via a Brownfields Property Application dated September 17, 2020 and an amended Brownfields Property Application dated January 18, 2021. As part of the Brownfields Application process, Hart & Hickman, PC (H&H), on behalf of the seller of the Subject Property, Gas-Fired Products, Inc., submitted a Site Operations Plan (SOP)-Revision 1 dated December 10, 2020 to the NCDEQ Brownfields Program. In the SOP, H&H provided details of the chemicals used at the Subject Property. Gas Fired Products, Inc. is continuing operations at the Subject Property after Cousins Tremont Doggett, LP take possession of the Subject Property. As such, the NC DEQ Brownfield Program has indicated that chemical usage by Gas Fired Products, Inc. will need to be discontinued and no storage of chemicals is to be allowed at the Subject Property. The NC DEQ has requested that Compliance Audits be completed on a quarterly basis to assess Gas Fired Products, Inc’s adherence to the SOP. NOVA prepared an Environmental Site Assessment Work Plan for supplemental subsurface assessment of the Doggett Street & West Tremont Avenue Site dated June 11, 2021. This work plan was approved by the NC DEQ Brownfields Program on July 15, 2021. Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 9 NOVA’s Supplemental Subsurface Assessment was conducted on the Subject Property to further assess the potential impact of the identified RECs on soil, groundwater, and soil gas at the Subject Property. 1.2 LIMITATIONS NOVA has performed this assessment in general accordance with ASTM 1903-19 and the North Carolina Department of Environmental Quality (NCDEQ) Brownfields Program, which is a limited inquiry into a property's environmental status and is not sufficient to discover every potential source of environmental liability or environmental impact, if any, of the property to be evaluated. No assessment can wholly eliminate uncertainty regarding the potential for Recognized Environmental Conditions (RECs) in connection with a property. Performance of this assessment is intended to reduce, but not eliminate, uncertainty regarding the potential for RECs in connection with a property, and this practice recognizes reasonable limits of time and cost. The level of inquiry is variable. Not every property will warrant the same level of assessment. Consistent with good commercial or customary practices, the appropriate level of assessment will be guided by the type of property subject to assessment, the expertise and risk tolerance of Cousins Tremont Doggett LP (Client or User), and the information developed in the course of the inquiry. NOVA’s assessment represents our professional opinion, only. Therefore, NOVA cannot, under any circumstances, make a statement of warranty or guarantee, expressed or implied, that RECs, environmental impairment, or environmental impacts are limited to those that are discovered while we are performing the Supplemental Subsurface Assessment . 1.3 USER RELIANCE NOVA’s Supplemental Subsurface Assessment report, along with the findings and conclusions contained in the report, either in completed form, summary form, or by extraction, is prepared, and intended, for the sole use of the Client and therefore may not contain sufficient information for other purposes or parties. The Client is the only intended beneficiary of this report. The contents of NOVA's report will continue to be the property of NOVA. NOVA's report may not be disclosed to, used by, or relied upon by, any person or entity other than the Client without the express written consent of NOVA. Authorization for disclosure to a third party or authorization for third-party reliance on a final report of any report will be considered by NOVA upon the written request of the Client. NOVA reserves the right to deny authorization to allow disclosure or reliance of NOVA's report to third parties. Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 10 2.0 SUPPLEMENTAL SUBSURFACE ASSESSMENT Cousins Tremont Doggett, LP requested that NOVA conduct a Supplemental Subsurface Assessment in general accordance with NOVA’s June 11, 2021, Environmental Site Assessment Work Plan to further assess the potential impacts to soil, groundwater and soil gas on the Subject Property from the above referenced RECs. Our investigation procedures, findings, conclusions, and recommendations are presented in the following sections. A receptor survey was completed and included in Appendix F. 2.1 SOIL BORING INSTALLATION AND SOIL SAMPLING On August 30 & 31, 2021, NOVA provided oversight for the advancement of four (4) soil borings (S-6 through S-9) on the Subject Property. Borings were advanced to termination depths between 12 feet and 30 feet below ground surface (bgs), using direct push technology (DPT). A Boring and Sampling Location Map is provided as Figure 4 in Appendix A. Soil boring samples were collected at two (2) feet bgs and then at every four to five (4-5) feet bgs using a 1.5-inch dual tube sampling liner. The soil samples were field-screened using a Photo-Ionization Detector (PID) for the presence of organic vapors. Field screening and/or visual observations did not readily indicate impacted soil. Consequently, one (1) soil sample from the deepest portion of the unsaturated zone of each boring was submitted for laboratory analysis. Samples were collected from the following depths: Soil Boring Depth (in feet below ground surface) S-6 14-15 S-7 10-11 S-8 11-12 S-9 7-8 No elevated PID readings were identified in the soil collected from the four (4) soil borings advanced on the Subject Property. A total of four (4) soil samples were collected from soil borings S-6 through S-9 and were submitted to Waypoint Analytical (Waypoint) of Charlotte, North Carolina for the following analyses: • Volatile Organic Compounds (VOCs) by United States Environmental Protection Agency (US EPA) Solid Waste (SW)-846 Method 8260D, • Semi-Volatile Organic Compounds (SVOCs) by USEPA SW-846 Method 8270E, • Resource Conservation and Recovery Act (RCRA) Metals by USEPA SW-846 Method 6020B and 7471B, and Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 11 • Hexavalent Chromium by USEPA SW-846 Method 7199. 2.2 GROUNDWATER SAMPLING Four (4) temporary Monitoring Wells (MWs) were installed using direct push technology to the desired depth. The MWs were constructed of two (2) inch PolyVinyl Chloride (PVC) screen and riser by a North Carolina certified well driller. Between fifteen (15) and twenty (20) feet of machine-slotted screen was installed. New polyethylene tubing was lowered into the temporary monitoring wells and the boreholes were purged of three (3) to five (5) volumes using a peristaltic pump. Once water was allowed to recharge, groundwater samples were obtained for laboratory analysis. Four (4) groundwater samples (MW-1 through MW-4) were obtained for laboratory analysis. The collected groundwater samples were then submitted to Waypoint for the following analyses: • VOCs by USEPA SW-846 Method 8260D, • SVOCs by USEPA SW-846 Method 8270E, and • RCRA Metals by USEPA SW-846 Method 6020B and 7470A. 2.3 SOIL GAS SAMPLING NOVA collected six (6) soil gas samples and one (1) sub-slab sample from the Subject Property. The soil gas monitoring points were installed utilizing direct push technology to a maximum depth of five (5) feet below ground surface (bgs). Following the advancement of each soil gas sampling point, a length of 0.250-inch Interior Diameter (ID) flexible nylon tubing equipped with a particulate filter was inserted into the sampling point. The soil gas monitoring points were then filled with approximately four (4) inches of industrial quartz sand. The remaining portion of the sampling points were filled with granular bentonite in three (3) inch increments and hydrated with water to create an airtight seal between the sampling point and the atmosphere. Collected soil vapor samples were submitted to Waypoint for the following analysis: • VOCs by US EPA Method TO-15. 2.4 QUALITY CONTROL AND QUALITY ASSURANCE METHODS Field procedures and protocols used during the ESA were performed in general accordance with those prescribed in ASTM International (ASTM) Standard Practice for Environmental Site Assessments: Phase II Environmental Site Assessment Process, Designation: E1903-19, USEPA Region IV Science and Ecosystem Support Division (SESD) guideline document LSASDPROC-300-R4 dated June 11, 2020, for soil sampling, and guideline document SESDPROC-301-R4 dated April 26, 2017, for groundwater sampling. Supplemental Subsurface Assessment January 14, 2022 Doggett Street & West Tremont Avenue Site NOVA Project Number 3021011 Page 12 Samples were labeled with a distinct sample identification number, the sampler’s initials, and the date of collection. Each sample container was properly sealed, labeled, and placed in an ice chest (with ice) and transport to an accredited laboratory (Waypoint) which used USEPA SW-846 protocols.
