Graham Street near the proposed Charlotte Locomotive and Railcar Maintenance Facility (LRMF) in Charlotte, Mecklenburg County, North Carolina. A site location map is included as Figure 1, and a site map is included as Figure 2. Soil treatment and removal activities were conducted on behalf of the North Carolina Department of Transportation (NC DOT) in accordance with H&H’s Technical and Cost Proposal dated April 26, 2016. A brief background of this project is discussed below. NC DOT is developing multiple properties for the LRMF project. Parcel 32 and the adjacent property Parcel 31.1 will be developed under a NC DEQ Brownfields Agreement as part of the LRMF project. H&H previously conducted preliminary site assessment (PSA) activities on Parcel 32 in 2014. Widespread impacted soil was identified on the property. The primary contaminants that were identified at the site are total petroleum hydrocarbons (TPH), polychlorinated biphenyls (PCBs), and metals (including lead in soil above the characteristic hazardous waste threshold). The locations, depths, and analytical results of samples previously collected at the site are shown on the table and figures from H&H PSA report dated December 1, 2014, which are included in Appendix A. The NC DOT project will require soil (including impacted soil) to be cut from the northern portion of the Parcel 32 property. Soil impacted with TPH and lead was identified in the cut area. Concentrations of total lead (up to 28,700 mg/kg) and Toxicity Characteristic Leaching Procedure (TCLP) lead (398 mg/L) were detected in soil samples collected in this area. The TCLP lead exceeded the characteristically hazardous waste threshold (5 mg/L) for lead. The hazardous lead soil in the proposed cut area is shown on Figure 5 from the PSA in Appendix A 2 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Report\P-2918F_ Soil Treatment & Removal_Parcel 32_20160805.doc and is also shown on Figure 2 of this report. H&H estimated that there were roughly 550 cubic yards of hazardous lead impacted soil between the surface and four ft in this area. H&H prepared a Hazardous Soil Treatment and Removal Work Plan and Groundwater Sample Results (Soil Removal Work Plan) letter dated April 26, 2016 to address removal of the hazardous lead impacted soil. The Soil Removal Work Plan included treating the hazardous lead impacted soil on-site to non-hazardous levels with the option to reuse the treated soil in an on- site berm or dispose of the soil in a permitted Subtitle D landfill. NC DEQ approved both of these options in their letter dated May 6, 2016. At NC DOT’s request the soil was treated on-site and disposed at a Subtitle D Landfill. Other impacted soil in the area which is non-hazardous will be addressed separately as part of an Environmental Management Plan associated with the Brownfields project. The soil treatment and removal activities conducted on the northern portion of Parcel 32 are discussed below. 2.0 Soil Stabilization 2.1 Soil Stabilization Activities H&H mobilized to the site on May 9, 2016 through May 12, 2016 to oversee hazardous lead impacted soil stabilization activities in the proposed NC DOT cut area in the northern portion of Parcel 32. H&H contracted with A&D Environmental Services, Inc. (A&D) of High Point, North Carolina to conduct the soil stabilization activities and subsequent disposal of the impacted soil. Soil stabilization was conducted by mixing the stabilizer EnviroBlend 80/20 (provided by Premier Magnesia LLC) with the impacted soil in-place. The stabilization compound is a magnesium oxide powder blend that stabilizes and binds soil metals to lower metal leachability. Prior to conducting soil stabilization activities, a bench test was conducted to determine the proper dosage of EnviroBlend to use during stabilization activities. On March 10, 2016 H&H collected a soil sample from the location of previously detected highest lead impacted soil in the proposed treatment area using a stainless steel hand auger. The soil sample was submitted to 3 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Report\P-2918F_ Soil Treatment & Removal_Parcel 32_20160805.doc URSUS Remediation Testing and Technologies LLC of Mount Horeb, Wisconsin for the bench test analysis. Based on the bench test results, Premier Magnesia determined the amount of EnviroBlend required for stabilization to be approximately 5 percent (approximately 42 tons) of the weight of the impacted soil (estimated 825 tons). The bench test results are included in Appendix B. Prior to soil stabilization activities, limits of the impacted soil area were marked with spray paint. Asphalt and concrete located above the impacted soil were removed from the area using a trackhoe. The asphalt and concrete were properly disposed off-site. The material manifests for the disposed concrete are included in Appendix C. During stabilization activities, the contractor was directed to mix the impacted soil with EnviroBlend in the impacted soil area to a depth of four ft bgs using an excavator. Soil near the center of the excavation was mixed up to a total depth of five ft bgs. Potential dust was controlled by wetting the soil. The impacted soil remained within the footprint of the target treatment area during the soil mixing process. The approximate aerial extent of the treated hazardous lead impacted soil is shown on Figures 2 and 3. 2.2 Post-Stabilization Confirmation Sampling After blending of the EnviroBlend and soils was completed, confirmation samples were collected from blended soil area to determine if the soil was properly treated to non-hazardous levels. On May 16 and 17, 2016, H&H and our subcontracted drilling firm installed 90 soil borings in the blended soil area using direct push technology (DPT). H&H utilized SAEDACCO, Inc. of Fort Mill, South Carolina to advance the soil borings. Composite soil samples were collected in triplicate using the incremental sampling procedure in accordance with Interstate Technology & Regulatory Council (ITRC) incremental sampling protocol as requested by Ms. Harvi Cooper of NC DEQ. In accordance with the sampling protocol, the blended soil area (decision unit) was sampled at a minimum of 30 locations as described below. The locations were selected using a systematic random approach so that a 95 4 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Report\P-2918F_ Soil Treatment & Removal_Parcel 32_20160805.doc % Upper Confidence Level (UCL) could be calculated for comparison to regulatory screening levels, if needed. Prior to sampling, the decision unit was divided into a grid of 30 cells. The perimeter of the decision unit was outlined with flags and the rows for the grid cells were marked with white marking paint. The initial composite sample (CS-1) was collected by advancing a soil boring to the base (approximately 4 ft bgs) of the total depth of the blended soil at a similar location in each cell. Using the systematic random sampling approach, a random soil boring location was identified in the first grid cell and subsequent soil borings were advanced in adjacent cells sequentially in a serpentine pattern using the same relative location within each cell. Aliquots of soil were then collected from the midpoint of the treatment depth (approximately 2 ft bgs) in each boring and placed into the same container for mixing. Because the soil was mixed during stabilization activities, multiple sampling depths were not required. Two replicate samples (CS- 2 and CS-3) were then collected from separate boring locations from within each grid cell using the same method as the original sample. During sampling activities, the soil boring locations associated with each composite sample were marked with a different colored flag that represented each composite sample to ensure consistent sampling throughout the grid cells. The sampling grid and composite sampling layout are shown on Figure 3. The three soil samples (CS-1 through CS-3) were placed in a cooler on ice and submitted to Prism Laboratories, Inc. under chain of custody protocol. Because NC DOT chose to dispose of the treated soil in a Subtitle D landfill, the composite samples were analyzed for TCLP RCRA Metals by EPA Methods 6010/7470. The laboratory utilized multiple incremental composite sampling procedures to collect the appropriate amount (100 grams) of sample for extraction and analytical method selected. Laboratory analytical data sheets and chain-of-custody documentation are included in Appendix D. The analytical results are discussed below. After the composite sampling activities were completed, the treated soil was covered and protected from rainfall to prevent run-off while awaiting confirmation sampling results. 5 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Report\P-2918F_ Soil Treatment & Removal_Parcel 32_20160805.doc 2.3 Post-Stabilization Analytical Results No target constituents were detected above the laboratory reporting limits in composite soil samples CS-1 through CS-3. The TCLP lead detection limits of <0.050 mg/L are well below the pre-stabilization TCLP lead concentration of 398 mg/L and the hazardous waste threshold of 5 mg/L. The analytical results are summarized in Table 1. Based on confirmation sampling results, the hazardous lead impacted soil was successfully treated to non-hazardous levels. The stabilized soil was then excavated and properly disposed in a Subtitle D landfill. The soil excavation and disposal activities are discussed below. 3.0 Soil Excavation Activities 3.1 Soil Excavation H&H mobilized to the site on June 16, 2016 through June 21, 2016 to oversee excavation and removal of the stabilized soil in the northern portion of Parcel 32. Prior to the removal of stabilized soil, a non-hazardous waste generator profile was completed and submitted to Republic Services Charlotte Motor Speedway Subtitle D Landfill in Concord, NC. H&H’s subcontractor A&D conducted excavation and transportation of the stabilized soil to the disposal facility. The stabilized soil was excavated to a depth of approximately four ft bgs throughout the excavation area and to approximately five ft bgs near the center of the excavation using a trackhoe. The soil was loaded directly onto dump trucks and transported to the disposal facility. Approximately 859.60 tons of non-hazardous impacted soil were transported for disposal at the Charlotte Motor Speedway Landfill. The non-hazardous waste manifests and weight tickets are included in Appendix C. The approximate extent of the excavation area is shown on Figure 4. After excavation activities were completed, the excavation was backfilled using soil that was located beneath the footprint of the former building that was located on the northern portion of the site. The soil that was cut and moved into the new excavation area will ultimately be cut again and moved to the proposed berm location on Parcel 31.1 within the Brownfields property 6 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Report\P-2918F_ Soil Treatment & Removal_Parcel 32_20160805.doc (see Figure 2). The excavation area was backfilled in approximate one foot lifts and compacted with the excavator. The former building footprint area and the excavation area were completed with a gentle slope to match the existing topography and natural surface drainage at the site. Concrete footers that were exposed during excavation and backfilling activities were removed from the site and properly disposed. The area was then stabilized with seed and straw to prevent erosion. The material manifest for disposed concrete is included in Appendix C. Photographs of the stabilization and excavation activities are included in Appendix E. Prior to backfilling the excavation area, confirmation samples (SW-1 through SW-4 and B-1) were collected from each sidewall and the base of the excavation. The samples were collected using the bucket of the excavator. Sidewall samples (SW-1 through SW-4) were collected from approximately two ft bgs on each sidewall. The base sample (B-1) was collected from a depth of approximately five ft bgs near the center of the excavation. Samples were submitted to Pace Analytical Services, Inc. for analysis of total RCRA Metals (plus antimony) by EPA Methods 6010/7471 and for TCLP RCRA Metals by EPA Methods 6010/7470. Antimony was included because it was previously detected above the Industrial Health-Based Soil Remediation Goal (SRG) in this area. Laboratory analytical data sheets and chain-of-custody documentation are provided in Appendix D. The analytical results are discussed below. 3.2 Post-Excavation Analytical Results Low level concentrations of antimony, barium, cadmium, chromium, lead, and/or mercury were detected in each of the confirmation samples. These metal detections do not exceed the IHSB Industrial Health-Based SRGs. Low level concentrations of TCLP barium, cadmium, and/or lead were detected in the confirmation samples SW-1, SW-3, SW-4, and B-1; however, the detected levels did not exceed the characteristically hazardous waste thresholds. A summary of analytical results are included in Table 2 and the TCLP sample locations are presented on Figure 4. 7 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Report\P-2918F_ Soil Treatment & Removal_Parcel 32_20160805.doc 4.0 Summary and Recommendations H&H has completed stabilization and excavation of hazardous lead impacted soil in the proposed NC DOT work areas in the northern portion of Parcel 32. Lead impacted soil exceeding the characteristically hazardous waste threshold was identified in the proposed NC DOT cut area on Parcel 32 during assessment activities conducted by H&H in 2014. With NC DEQ approval, NC DOT requested that the soil be treated on-site to non-hazardous levels and disposed in a Subtitle D landfill. The hazardous lead impacted soil was treated and stabilized on site by mixing the stabilizer EnviroBlend with the hazardous lead impacted soil. The Enviroblend stabilizing compound and impacted soil were blended in-place using an excavator. After blending of the EnviroBlend and soils was completed, confirmation samples were collected from the stabilized soil using incremental sampling protocol as instructed by NC DEQ. TCLP analytical results of the composite samples collected from the stabilized soil indicate that the soil was successfully treated to non-hazardous levels. Approximately 859.60 tons of stabilized impacted soil were excavated and transported for disposal at a Subtitle D landfill as non-hazardous waste. After excavation activities, post- excavation soil samples were collected from the sidewalls and base of the excavation. Analytical results indicated the presence of low level metals below the Industrial SRGs and TCLP metals including barium, cadmium, and/or lead below characteristic hazardous waste thresholds in the post-excavation soil samples. No attempt was made to remove other non-hazardous impacted soil in this area of the site. Other impacted soil in the area will be addressed separately as part of an Environmental Management Plan associated with the Brownfields project.
