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. In accordance with the Brownfields Agreement (BFA), within 90 days of each one year anniversary of the effective date (October 24, 2016) of the BFA during redevelopment for the Brownfields property, and/or at the completion of redevelopment activities, H&H, on behalf of NC DOT, will submit a report to DEQ documenting the redevelopment and environmental activities conducted on the Brownfields property for the reporting period. A general summary of Ms. Carolyn Minnich January 18, 2018 Page 2 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Brownfields Update Report\P-2918F_BF Update Letter Parcel 31.1-32_20180118.doc activities conducted at the Brownfields property over the past year is provided below. The Brownfields property is currently being redeveloped as part of the NC DOT LRMF project. Construction activities started on the LRMF project in October 2016. Mass grading of the LRMF project and the Brownfields property is near completion. NC DOT’s construction contractor, Zoladz Construction Company, Inc. (Zoladz) is still working on completing final construction activities associated with the railroad service tracks, service platform, compressor building, landscaping, etc. on the Brownfields property which is expected to be completed in March of 2018. A summary of environmental reports associated with the site that have recently been submitted to DEQ are provided below. - Environmental Management Plan - Charlotte Locomotive and Railcar Maintenance Facility, May 6, 2016 - Hazardous Soil Treatment and Removal Activities - NC DOT Parcel 32, August 5, 2016 - Brownfields Soil Sampling - NC DOT Parcel 32, June 23, 2016 - Brownfields Soil Berm Sampling - NC DOT Parcel 31.1/32, June 15, 2017 2.0 Environmental and Redevelopment Activities Summary Based on historical assessment activities, widespread impacted soil was previously identified on the Brownfields property. The primary contaminants are total petroleum hydrocarbons (TPH), polychlorinated biphenyls (PCBs), and metals (including lead above characteristically hazardous waste thresholds). A portion of the lead impacted soil above hazardous waste thresholds was located in the proposed LRMF cut area on the northern portion of Parcel 32. Prior to construction activities in May 2016, this hazardous soil was treated on-site to stabilize the lead impacts to below hazardous waste thresholds. The treated non-hazardous soil was then removed from the proposed cut area and disposed at a Subtitle D landfill. The hazardous soil treatment Ms. Carolyn Minnich January 18, 2018 Page 3 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Brownfields Update Report\P-2918F_BF Update Letter Parcel 31.1-32_20180118.doc activities are documented in H&H’s Hazardous Soil Treatment and Removal Activities report dated August 5, 2016. The LRMF project also required soil (including low-level non-hazardous impacted soil) to be cut from the northern portion of the Brownfields property Parcel 32. As part of the LRMF construction activities, Zoladz reused the cut soil from the northern portion of the Brownfields property Parcel 32 in a privacy berm on the Parcel 31.1 portion of the Brownfields property (see Figure 2). The NC DEQ Brownfields program previously approved reuse of this cut soil for construction of the berm. Soil that was cut from the northern portion of Parcel 32 was below NC DEQ IHSB Industrial Health-Based Soil Remediation Goals (SRGs) except for a small stockpile of soil (approximately 20 tons) which contained polynuclear aromatic hydrocarbons (PAHs) and PCBs above the Industrial SRGs. The soil that exceeded the Industrial SRGs was placed near the center and at the base of the berm and capped with at least two ft of cover soil that was not impacted above Industrial SRGs. Analytical results of soil samples previously collected from the cut area on Parcel 32 are documented in H&H’s Preliminary Site Assessment report dated December 1, 2014 and Brownfields Soil Sampling - NC DOT Parcel 32 report dated June 23, 2016. As mentioned above, during LRMF construction activities, Zoladz reused the cut soil from the northern portion of the Brownfields property Parcel 32 in a privacy berm on the Parcel 31.1 portion of the Brownfields property. However, in April 2017, Zoladz capped the entire berm with 2 ft of fill material (approximately 2,500 cubic yards) that was cut from an area of the LRMF project that is located approximately 300 ft east of Parcel 32 and outside of the Brownfields property boundary. Because the approved Environmental Management Plan (EMP) for the Brownfields property indicates that fill material must be sampled before it can be imported onto the Brownfields property, DEQ requested that the berm cap be sampled. H&H completed sampling of the berm soil cap in May 2017. Low level detections of PCBs and/or metals below the Industrial SRGs were detected in soil samples collected from the berm cap. Because the detected constituents were below Industrial SRGs, the berm cap was left in place. Ms. Carolyn Minnich January 18, 2018 Page 4 S:\AAA-Master Projects\NC DOT Right-of-Way -ROW\ROW-500s\ROW-510 P-2918F Hazardous Soil & Brownfields\Brownfields Update Report\P-2918F_BF Update Letter Parcel 31.1-32_20180118.doc Upon completion of the berm cap soil sampling activities, the berm was seeded and mulched by Zoladz using hydroseeding to prevent erosion of the berm. The berm soil sampling activities are documented in H&H’s Brownfields Soil Berm Sampling - NC DOT Parcel 31.1/32 report dated June 15, 2017. At Zoladz request, in February 2017, H&H requested DEQ approval for temporary use of heavy machinery for crushing rock (blasted and removed from other areas of the LRMF project) and for storage of the crushed rock on the Brownfields property. DEQ requested that Zoladz submit a work plan to address preserving and restoring the integrity of the asphalt parking lot which is serving as a protective cap in an area of known soil contamination on the Brownfields property. Zoladz is responsible for repairing any areas of asphalt or concrete damaged from rock storage and rock crushing operations and managing impacted soil if encountered, etc. Zoladz work plan was approved by DEQ on February 8, 2017. Crushed rock piles, railroad construction materials, and some heavy machinery are currently stored on the Brownfields property. Once all stored materials and heavy machinery are removed, Zoladz will repair and repave damage to the asphalt parking lot. Construction activities associated with the LRMF project and redevelopment of Brownfields Parcels 31.1/32 started in late 2016. NC DOT’s contractor is currently working on completing final construction activities associated with the service tracks, service platform, compressor building, landscaping, etc. on the Brownfields property. The project is expected to be completed in March 2018. Different phases of redevelopment of the Brownfields parcels are shown in photos which are included in Appendix A.
