A Site location map is provided as Figure 1. The HD Supply Brownfields property was initially comprised of one approximately 3.38-acre parcel of land solely owned by RailYard, LLC (formerly Beacon MPI, LLC). However, RailYard, LLC sold an approximately 0.74-acre area in the western portion of the Site to Centro RailYard, LLC on November 27, 2018. Currently, the HD Supply Brownfields property is comprised of two parcels. The larger approximately 2.77-acres parcel (Parcel No. 07309204) is owned by RailYard, LLC and has been developed with two multi -purpose high-rise towers (retail and commercial office space) and a parking deck. The smaller approximately 0.74-acre parcel (Parcel No. 07309217) is owned by Centro RailYard, LLC and is being developed with a multi -story building including retail commercial units on the ground floor with multi -family residential apartment units above. A Site map is provided as Figure 2. 1.1 Site History Historically, the subject Site was developed with multiple residential structures prior to 1911 based on review of historic Sanborn Fire Insurance maps. The southeastern portion of the Site was redeveloped for commercial purposes in 1946 when an approximately 36,000 square foot (sq ft) multi -use building was constructed. The multi -use building was used as a drycleaner and laundry facility from initial construction to the late 1960s or early 1970s. From the early 1970s through 1 hart '` hickman SAAAA-Master Projects\Beacon Partners- BEP or BCP\BCP-064 1414 and 1422 S. Tryon\Brownfields\Final Grade Sampling Work PlanTinal Grade . Sampling Report - HD Snpply.doc SMARTER ENVIRONMENTAL SOLUTIONS 2017 when the building was demolished, the multi -use building was used as a furniture showroom, offices, and warehouse storage. The western portion of the Site was developed with an approximately 7,700 sq ft warehouse building in 1984 and was occupied by HD Supply for office space and electrical supply warehousing from 1984 until 2017 when the building was demolished. A Site map is provided as Figure 2. 1.2 Previous Brownfields Assessment Activities Details of previous assessment activities conducted at the Site are provided in the Brownfields Assessment Report dated June 19, 2017 and the Soil Characterization Report dated January 11, 2019. A brief summary of previous assessment activities detailed in these reports is provided below: Brownfields Assessment Report Based on the results of the assessment activities, H&H concluded the following: • Soil with compound concentrations above Residential and/or Industrial PSRGs is only present in shallow soil in the area of soil samples SB-4 and SB-6. Results of TCLP analysis of soil from this area indicates that the soil is not a characteristically hazardous waste. • Results of the soil gas sampling indicate that concentrations of PCE and 1,2,4- trimethylbenzene were detected above Residential VISCs in the sample from SG-6 located below the southwestern portion of the proposed residential apartments. Results of cumulative risk calculations indicate that cumulative risks for this sample did not exceed the acceptable LICR risk range of 1 x 10-4 to 1 x 10-6 for potential carcinogenic risks or the threshold HI of 1 for potential non -carcinogenic risks, although the calculated HI was 0.91 and close to 1. No other soil gas samples in the area of the proposed apartments contained compound concentrations above Residential SGSLs and no soil gas samples in the area of the proposed office building contained compound concentrations above Non -Residential SGSLs. 2 hart "� hickman SAAAA-Master Projects\Beacon Partners- BEP or BCP\BCP-064 1414 and 1422 S. Tryon\Brownfields\Final Grade Sampling Work PlanTinal Grade . Sampling Report - HD Snpply.doc SMARTER ENVIRONMENTAL SOLUTIONS Based on the results of the assessment activities, H&H recommends the following: • H&H recommends that shallow soil impacts above PSRGs in the area of borings SB-4/SB-6 be managed in accordance with an Environmental Management Plan (EMP). This soil is located where the southern office building is proposed. If the building is constructed concurrently with the rest of the development as currently anticipated, the soil may potentially be left in place below the building or potentially moved to other areas of the site to be covered with impervious surface such as the proposed parking deck. If the southern office building will be constructed after the remainder of the development and this area will initially be used as green space, then the shallow impacts will likely need to be excavated and disposed off -site or moved to other areas of the site to be covered with impervious surface such as the proposed parking deck. The subsurface structure identified in this area should also be removed as part of the site grading activities. H&H recommends that vapor mitigation be included for the proposed southern office building. Because the calculated cumulative HI for sample SG-6 was just below the threshold level of 1, H&H also recommends that vapor mitigation be included for the southwestern "leg" of the apartment building in the area of sample SG-6. Soil Characterization Report Prior to the start of development activities, H&H characterized soil at the Site to expedite soil management during development activities. Results of the soil characterization activities are provided below: • Analytical results did not indicate the presence of VOCs, SVOCs, or RCRA metals in the shallow or deep samples collected from Sections 1, 2, 3, or 4 at concentrations above Residential or Commercial/Industrial PSRGs. • The shallow soil sample collected from section 5 (SC-5S) indicated the presence of several SVOCs above laboratory reporting limits, but below Residential and Commercial/Industrial 3 hart '` hickman SAAAA-Master Projects\Beacon Partners- BEP or BCP\BCP-064 1414 and 1422 S.

Additionally, the polynuclear aromatic hydrocarbons (PAHs) benzo(a)pyrene, benzo(b)fluoranthene, and dibenz(a,h)anthracene were detected at concentrations above the Residential PSRGs, but below the Commercial/Industrial PSRGs. Additionally, arsenic was detected above Residential and Commercial/Residential PSRGs. • The deeper sample collected from Section 5 did not indicate the presence of VOCs or SVOCs at concentrations above Residential or Commercial/Industrial PSRGs. Arsenic was detected at 1.8 J mg/kg in the deeper sample from section 5 which is above the Residential PSRG, but is below the Commercial/Industrial PSRG. • The shallow soil sample collected from section 6 indicated the presence of tetrachloroethene (PCE) at a concentration of 0.0024 mg/kg which is below Residential and Commercial/Industrial PSRGs. Additionally, arsenic was detected in the shallow sample at a concentration of 2.2 J mg/kg which is above the Residential PSRG, but below the Commercial/Industrial PSRG. No other VOCs, SVOCs, or RCRA metals were detected in the shallow or deeper soil samples collected from section 6 at concentrations above Residential or Commercial PSRGs. • Analytical results indicate the presence of PCE and trichloroethene (TCE) at low concentrations below the Residential and Commercial/Industrial PSRGs in the shallow and deeper samples collected from section 7. No SVOCs or RCRA metals were detected above Residential or Commercial PSRGs in the soil samples collected from section 7. 4 hart '` hickman SAAAA-Master Projects\Beacon Partners- BEP or BCP\BCP-064 1414 and 1422 S. Tryon\Brownfields\Final Grade Sampling Work PlanTinal Grade . Sampling Report - HD Snpply.doc SMARTER ENVIRONMENTAL SOLUTIONS 2.0 Scope of Work The subject Site is predominately covered with hardscape surfaces with the exception of a small grassed courtyard located between the two Site tower buildings. As such, the purpose of the final grade sampling activities will be to collect representative soil samples of the grassed area. The small courtyard area is depicted on Figure 2. The proposed final grade soil sampling activities will be performed in general accordance with DEQ's Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup (Guidelines) dated January 2020 and most recent version of the U.S. Environmental Protection Agency (EPA) Region IV Science and Ecosystem Support Division (SESD) Field Branches Quality System and Technical Procedures guidance. 2.1 Soil Sampling H&H proposes to advance three shallow soil borings in the grassed courtyard located between the northern and southern tower buildings. Soil borings will be advanced to approximately 2 feet (ft) below ground surface (bgs) at each boring location utilizing a decontaminated stainless -steel hand auger. Continuous soil samples will be collected from the center of the hand auger bucket at each soil boring and described for lithologic purposes, observed for the presence of staining, and field screened for elevated volatile organic vapors using a calibrated photo -ionization detector (PID). Aliquots of soil from each boring will be placed into a stainless -steel bowl and homogenized to form one composite soil sample. H&H will also collect a grab sample from one soil boring for laboratory analysis of volatile organic compounds (VOCs) from the soil boring exhibiting the highest likelihood for potential impact based on field screening results. If no obvious evidence of impact is observed at the boring locations, a grab sample will be collected from the 1 ft to 2 ft bgs interval at a randomly selected soil boring. The final grade soil samples selected for laboratory analysis will be collected directly into laboratory supplied glassware, labeled with the sample identification, date, time, and requested analysis and 5 hart '` hickman SAAAA-Master Projects\Beacon Partners- BEP or BCP\BCP-064 1414 and 1422 S. Tryon\Brownfields\Final Grade Sampling Work PlanTinal Grade . Sampling Report - HD Snpply.doc SMARTER ENVIRONMENTAL SOLUTIONS placed on ice in a laboratory supplied cooler. The sample will be delivered to a North Carolina certified laboratory under standard chain of custody protocols for analysis of VOCs by EPA Method 8260, semi -volatile organic compounds (SVOCs) by EPA 8270, and RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7199. A sample and analytical summary are provided on Table 1. 2.2 Quality Assurance/Quality Control H&H will collect one duplicate soil sample for QA/QC purposes. Additionally, H&H will collect an equipment blank to evaluate the effectiveness of the field equipment decontamination methods. To collect the equipment blank, laboratory supplied analyte free water will be poured over the decontaminated stainless -steel hand auger. The water will be collected off the hand auger directly into laboratory supplied sample containers. The duplicate soil sample and the equipment blank will be submitted for analysis of VOCs by EPA Method 8260, SVOCs by EPA 8270, and RCRA metals plus hexavalent chromium by EPA Methods 6020/7471/7199. H&H will request a Level II QA/QC data package from the laboratory and the laboratory will report compound detections to the laboratory -specified method detection limits using J-flags. 2.3 Boring Abandonment and Investigation Derived Waste Investigation derived waste (IDW) generated during the sampling activities will be thin spread in the area of generation, unless there is evidence of significant impact (such as free product). If there is evidence of significant impact, the investigation derived waste from that area will be containerized in 55-gallon drums. If wastes are containerized, then a composite sample of the materials will be obtained for waste disposal purposes. Following sampling activities, the soil borings will be properly abandoned and the surface will be repaired similar to pre -sampling conditions. 6 hart '` hickman SAAAA-Master Projects\Beacon Partners- BEP or BCP\BCP-064 1414 and 1422 S.
