A site location map is presented as Figure 1. The purpose of the SMP is to present measures to address soil that will be excavated during redevelopment of the site. The subject property is 4.16 acres in area and contains an approximate 16,000 sq ft commercial building located in the northeastern portion of the site. Four other buildings were previously located at the site but have been demolished, although their foundations remain. The site is bordered to the west by the Charlotte light rail line with residences located beyond, to the south by vacant land (which is part of the Southline Brownfields project which is to be redeveloped as apartments by Camden), to the north by the Atherton Lofts live/work condominiums and a bank, and the east by South Blvd. with a Lowe’s Home Improvement Center located beyond. The redevelopment plans for the site include demolition of the existing structure and foundations and construction of a large commercial building that will be used for retail purposes by several tenants. The remainder of the property will primarily be paved access areas, although there will be some landscape strips. A two-level subterranean parking structure will underlie the commercial building, with 1.5 levels below ground that will be mechanically vented per code. The grading plan calls for net export of approximately 38,800 cubic yards of soil from the site. A grading plan with anticipated cut and fill depths and areas is provided as Figure 2. Cut areas and depths are shown in red, and fill areas and depths are shown in green. Cut S:\AAA-Master Projects\Stiles - SLS\SLS-001 South Blvd\SMP\Soil Mgmt Plan Phase II.doc depths generally range from 10 to 23 ft from current grade in the central and eastern portions of the site to less than 1 to 3 ft below current grade in the northern portion of the site. Fill depths are primarily in the west-central and southern portions of the site and range from less than 1 ft to approximately 11 ft from current grade. In November 2012, H&H evaluated previous soil assessment data to determine what areas of the cut soils had been previously sampled and to propose a plan to manage these soils. The results of the evaluation were presented in a Phase I SMP dated November 19, 2012 that included the following:  Cut soil from 0 to 5 ft in southern portion of the site (enclosed in dashed red lines on Figure 2), and soil from 0 to 3 ft in the northwestern portion of the site (enclosed in dashed purple lines on Figure 2) will be transported to the adjacent Southline Brownfields project located at 2300 and 2316 South Blvd (which is located south of the Carolina Metals site) and used for fill. The volume of this soil is approximately 8,900 cubic yards.  Because of the presence of several polynuclear aromatic hydrocarbons (PAHs) in the GP-15 soil sample above North Carolina Department of Environment and Natural Resources (DENR) Inactive Hazardous Sites Branch Soil Remediation Goals (SRGs), cut soil in the area of previous sample location GP-15 as depicted on Figure 2 will be used for on-site fill either in the southern portion of the site or in the adjacent fill area to the east of sample GP-15. Both of these areas will be covered with pavement after completion of the site construction activities. The Phase I SMP was approved by the North Carolina Department of Environment and Natural Resources (DENR) in a letter dated January 24, 2013. As part of the approval letter DENR specified the following conditions:  Soil excavated must be moved directly to the adjacent Southline Brownfields site and must not be taken on any roads. S:\AAA-Master Projects\Stiles - SLS\SLS-001 South Blvd\SMP\Soil Mgmt Plan Phase II.doc  DENR must be notified of any unusual conditions within 24 hours.  DENR must be notified of placement of soil and the Brownfields plat must be updated accordingly. As part of the Phase I SMP, H&H proposed that additional soil samples be collected at locations and depths of the proposed cut soil not included in the Phase I SMP so that appropriate management of that soil could be determined. H&H conducted the additional soil assessment in February 2013. The methods and results of the soil sampling activities and a plan for management of the remaining areas of cut fill are summarized in the following sections. S:\AAA-Master Projects\Stiles - SLS\SLS-001 South Blvd\SMP\Soil Mgmt Plan Phase II.doc 2.0 February 2013 Soil Assessment 2.1 Sampling Methodology On February 6, 2013, five soil borings were advanced to characterize cut soil at the site which has not been previously sampled. H&H utilized Probe Technology, Inc. of Concord, North Carolina to advance the soil borings using Geoprobe® direct-push technology (DPT) equipment. Soil cores were continuously retrieved within acetate sleeves for visual characterization and soil vapor screening using a photo-ionization detector (PID). Boring logs including PID readings are provided in Appendix A. One or two 4 ft long samples were collected from each soil boring for laboratory analysis. The locations of the proposed soil borings are indicated on Figure 3 and are described below:  Soil borings SB-A and SB-B were advanced in areas where shallow soils had been previously assessed to a depth of 4 ft and cut depths are approximately 11 ft. Therefore, a soil sample from each of these borings was collected from 6 to 10 ft below ground surface (bgs).  Soil borings SB-C and SB-E were advanced in areas where previous samples had not been collected and where excavation depths up to approximately 23 ft below current grade are planned. Soil samples were collected from these borings at depths of 6 to 10 ft bgs and 16 to 20 ft bgs.  Soil boring SB-D was advanced in an area where previous samples had not been collected and where excavation depths are up to approximately 16 ft below current grade. Soil samples were collected from this boring at depths of 4 to 8 ft bgs and 12 to 16 ft bgs. S:\AAA-Master Projects\Stiles - SLS\SLS-001 South Blvd\SMP\Soil Mgmt Plan Phase II.doc All eight of the soil samples were analyzed for volatile organic compounds (VOCs) by EPA Method 8260, PAHs by EPA Method 8270, and the following nine metals: arsenic, cadmium, total chromium, hexavalent chromium, lead, mercury, nickel, selenium, and thallium by EPA Method 6010/7471/7196A. The samples were submitted to TestAmerica, Inc., a North Carolina-certified laboratory. Dedicated laboratory-supplied sample kits and bottles were used for sample collection. The samples were placed in an iced cooler after collection. A chain-of-custody record was completed for the samples collected and included the sample description, date collected, time collected, matrix, sample container information, and analyses required. The chain-of-custody was signed by H&H prior to placement in the iced sample cooler for delivery to the laboratory. 2.2 Soil Analytical Results The results of the soil sample analyses are summarized in Table 1, and the laboratory analytical report is provided in Appendix B. The results indicate that VOCs and PAHs were not detected above the laboratory reporting limits in any of the eight soil samples. Several metals including chromium, lead, nickel, and selenium were detected in the soil samples; however, the detected concentrations are well below the DENR Inactive Hazardous Sites Branch (IHSB) Residential and Commercial/Industrial SRGs and are consistent with typical background levels. Results of the chromium speciation indicated that hexavalent chromium was not detected above the laboratory reporting limits in any of the samples; therefore, the detected chromium concentrations (13.7 mg/kg to 65.0 mg/kg) are comprised of trivalent chromium. The detected trivalent concentrations are well below the SRG for trivalent chromium. The results of analysis of the additional soil samples did not indicate the presence of soil impacts that would warrant special management of the soil. S:\AAA-Master Projects\Stiles - SLS\SLS-001 South Blvd\SMP\Soil Mgmt Plan Phase II.doc 3.0 Proposed Environmental Action Based upon the existing soil analytical data, shallow and deeper soil at the site is not impacted above Residential or Commercial/Industrial SRGs, except for an isolated area near sample GP-15 in the west-central portion of the site. H&H has developed a Phase II SMP based upon the soil analytical data for the site. Soil in the following areas will be managed as described below: 1. As approved in the Phase I SMP, cut soil in the area of previous sample location GP-15 (enclosed in dashed blue lines on Figure 3) will be used for on-site fill either in the southern portion of the site or in the adjacent fill area to the east of sample GP-15. As mentioned in Section 2.0, both of these areas will be covered with pavement after completion of the site construction activities. DENR will be notified of the location of these soils, and the Brownfields plat will be updated as needed. The total volume of this soil is approximately 3,200 cubic yards (based on an average cut depth of 10 ft) as indicated on Figure 3. 2. Up to approximately 22,000 cubic yards of cut soil in the area enclosed in dashed red lines on Figure 3 will be excavated during site redevelopment and transported to the adjacent Southline Brownfields project located at 2300 and 2316 South Blvd and used for fill. The soil will be transported directly across the property boundary and will not be taken on any roads. 3. The cut soil that is not used as fill at the Southline Brownfields project (approximately 16,800 cubic yards) will be transported off-site for use as fill or to a permitted landfill. At this time, the Developer (South End Partners, LLC) is evaluating options for off-site placement of the cut soil not taken to the adjacent Southline Brownfields site. DENR will be notified of the off-site proposed fill placement location(s) for review and approval prior to transporting the cut soil off-site.
