CATS is planning to conduct utility improvements at the Light Rail Maintenance facility which is located within the footprint of the Brownfields property. Soil generated during the utility improvements will be reused on site or it will be removed and properly disposed at a permitted facility. This work plan is being provided for your review and approval. A site location map is included as Figure 1, and a site map is included as Figure 2. CATS is planning to conduct two small projects that will disturb a limited volume of soil: 1. subgrade utility box replacements and 2. installation of cathodic protection for infrastructure including trenching and installation of associated equipment at the Light Rail Maintenance Facility. The CATS project will require soil (including potentially impacted soil) to be excavated Ms. Carolyn Minnich April 5, 2022 Page 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/City of Charlotte - CLT/CLT-600s/CLT-653 NSIF Brownfields Soil/BF Work Plan/BF Construction Work Plan (#15019-11-060)_20220405.doc from certain areas on the Brownfields property. H&H previously conducted soil and groundwater assessment activities at the site in 2014 prior to redevelopment of the Brownfields property. Assessment activities are documented in H&H’s Environmental Management Plan (EMP) Addendum dated September 25, 2014 and H&H’s Soil and Groundwater Assessment report dated May 18, 2015. Previous assessment activities at the site indicate that soil is impacted with volatile organic compounds (VOCs), semi-VOCs (SVOCs), and/or metals in certain areas on the Brownfields property. Certain metals and benzo(a)pyrene were detected above the 2014 Industrial/Commercial Health-Based Preliminary Soil Remediation Goals (PSRGs). Groundwater is also impacted with VOCs and metals above the 15A NCAC 2L .0202 groundwater Quality Standards. Pertinent tables and figures from H&H’s 2015 Soil and Groundwater Assessment Report are included Appendix A. H&H prepared an EMP and EMP Addendum in 2013 and 2014, respectively, for management of soil and groundwater for previous redevelopment activities associated with the Light Rail Maintenance facility. The EMP includes procedures for managing soil and groundwater during construction activities, and procedures for handling unexpected environmental conditions if encountered. In accordance with the NC DEQ approved EMP and the recorded land use restrictions associated with the Brownfields property, disturbance of soils deeper than 18 inches below existing grade level within the Brownfields property must be reviewed and approved by the NC DEQ Brownfields Program. During the previous 2014 assessment activities, soil in certain areas on the Brownfields property was identified to be managed as impacted during redevelopment activities. Impacted soil areas were defined based on the detected presence of contaminants, including metals at concentrations, which exceeded 2x background mean. These indicators were incorporated into a site-wide Soil Management Plan figure that outlined areas of the site to be managed as impacted for the overall NSIF property. In non-impacted areas, with appropriate environmental oversight and field screening, soil could be reused off-site on other portions of the Light Rail project at the time. This soil management strategy was approved by DENR in email correspondence dated October 16, 2014. Ms. Carolyn Minnich April 5, 2022 Page 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/City of Charlotte - CLT/CLT-600s/CLT-653 NSIF Brownfields Soil/BF Work Plan/BF Construction Work Plan (#15019-11-060)_20220405.doc The majority of the proposed CATS construction activities is located within areas previously designated to be managed as impacted soil. The previously identified soil areas to managed as impacted and the general location of the proposed construction activities are shown on Figure 2. Detailed construction plan sheets are included in Appendix B. The 2013 EMP indicates soil above the Industrial/Commercial PRSGs can be reused on site if it is covered with hardscape (asphalt, concrete, etc.) or a minimum of 2 ft of clean soil. For the proposed construction activities, disturbed soil will be reused as backfill to the extent practicable and covered under hardscape such as asphalt or concrete. Disturbed soil that cannot be reused on site will be disposed at a permitted Subtitle D landfill. Groundwater is not anticipated to be generated during construction activities. The soil management activities are described below. 2.0 Soil Management Activities During the proposed construction activities, soil will be excavated up to depths of 4 ft bgs (below ground surface) for replacement of three utility boxes and up to roughly 2 ft bgs for proposed cathodic protection trenching and installation of associated equipment. Two anodes will be installed in separate 10-inch diameter borings to total depths of 20 ft each. The utility box replacements, roughly 40 ft of trenching, and installation of anodes will be conducted near the eastern side of the existing maintenance building. Other associated equipment will be installed near four mop sink locations located adjacent to the Light Rail railroad spurs to the northeast of the maintenance facility. The general locations of the proposed construction activities are shown on Figure 2, and more detailed plans are shown on the CATS construction plan sheets which are included in Appendix B. During the construction activities the contractor will reuse excavated soil as backfill around the utility boxes, trenching, etc. to the extent practicable. Excavated soil that is anticipated to be reused as backfill will be temporarily stockpiled on and under plastic near the excavation areas. Soil will be reused at similar depths from which it was excavated. The excavation areas where Ms. Carolyn Minnich April 5, 2022 Page 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/City of Charlotte - CLT/CLT-600s/CLT-653 NSIF Brownfields Soil/BF Work Plan/BF Construction Work Plan (#15019-11-060)_20220405.doc soil is reused as backfill material will be covered with hardscape such as asphalt, concrete, etc. It is not anticipated that import fill will be required for this project. Excavated soil that cannot be reused on site will be loaded and staged in a roll-off container (by the construction contractor), characterized, profiled, and properly disposed at a permitted Subtitle D landfill. H&H estimates that one roll-off container (approximately 10 tons) of soil will be generated during the construction activities. The CATS construction contractor will provide the roll-off container and stage the container in a secure area on site. The roll-off container will be lined with 10 mil plastic and covered with a tarp. After the construction activities are complete H&H will collect a composite/grab sample from the roll-off container to characterize the soil for proper disposal. An aliquot of soil will be collected from the mid-point of the soil at two locations within the roll-off container using a decontaminated stainless steel hand auger. The aliquots will be field screened with a photoionization detector (PID). Prior to compositing the aliquots, soil collected from the aliquot with the highest PID reading will be placed into laboratory supplied sample containers for VOC analysis. The aliquots will then be placed into an inert container and thoroughly mixed using a nitrile glove covered hand or a decontaminated mixing tool. The composite soil sample will be collected into laboratory supplied sample containers, placed in an iced cooler, and submitted under chain of custody protocol to a NC certified laboratory for analysis of toxicity characteristic leaching procedure (TCLP) VOCs by EPA Method 8260, TCLP SVOCs by EPA Method 8270, TCLP RCRA metals by EPA Method 6010/7470, and TCLP herbicides by EPA Method 8151, as requested by Republic Services landfill. Following completion of the sampling activities and receipt of the analytical data, H&H will prepare a waste profile as required by the landfill for disposal of the soil. Once the profile is approved by the landfill, the soil will be transported and disposed at an off-site permitted Subtitle Ms. Carolyn Minnich April 5, 2022 Page 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/City of Charlotte - CLT/CLT-600s/CLT-653 NSIF Brownfields Soil/BF Work Plan/BF Construction Work Plan (#15019-11-060)_20220405.doc D landfill by the construction contractor. The anticipated landfill to be used by the construction contractor is Republic’s Charlotte Motor Speedway (CMS) landfill in Concord, NC. 3.0 Reporting Following completion of the assessment activities and receipt of the analytical data, H&H will document the soil management activities in brief letter report for CATS. A copy of the report will be submitted to your attention. The report will include a description of the construction and soil sampling activities, laboratory analytical data, soil disposal manifests, and conclusions concerning our activities. We look forward to your approval of this work plan. Should you have any questions or need additional information please do not hesitate to contact us at (704) 586-0007.
