Davidson Street and 421 E. 26th Street Charlotte, North Carolina Brownfields Project No. 24003-20-060 H&H Job No. PAM-003 1.0 Introduction On behalf of Mill District Partners, LLC, Hart & Hickman, PC (H&H) has prepared this work plan to conduct final grade soil sampling activities at the North Davidson II Brownfields property (Brownfields Project No. 24003-20-060) located at 2315 N. Davidson Street and 421 E. 26th Street in Charlotte, Mecklenburg County, North Carolina (Site). A Site location map is provided as Figure 1. The Site consists of two parcels of land (Parcel Identification Numbers 08305204 and 08305206) that total approximately 3.8 acres. The southeastern parcel (2315 N. Davidson Street) is developed with an approximate 28,675-square foot (sq ft) vacant commercial building, and the northwestern parcel (421 E. 26th Street) is developed with an approximate 12,960-sq ft vacant commercial building. An inactive rail corridor that is owned by the City of Charlotte separates the two Site parcels. Redevelopment at the Site includes adaptive re-use of the Site buildings for mixed- commercial purposes including retail, office, and restaurants, with landscaped areas and an outdoor patio on the eastern portion of the northwestern Site parcel. The building locations are shown on Figure 2. A Landscape Plan is provided as Appendix A, and a Paving Plan is included as Appendix B. An Environmental Management Plan (EMP) for the Site was approved by the North Carolina Department of Environmental Quality (DEQ) Brownfields Program on October 27, 2020. The EMP includes a requirement for collection of final grade soil samples in areas that are not covered with a minimum of 2 ft of clean fill soil or topsoil from a landscaping company, building foundations, sidewalks, asphalt or concrete parking areas, driveways, or other impervious surfaces following completion of redevelopment activities. 2 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/Final Grade Sampling/Work Plan/North Davidson II Final Grade Sampling Work Plan.docx This work plan has been prepared to detail proposed final grade soil sampling activities in accordance with the DEQ-approved EMP. A brief summary of Site background information is presented in Section 2.0, and the proposed final grade soil sampling scope of work is provided in Section 3.0. 3 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/Final Grade Sampling/Work Plan/North Davidson II Final Grade Sampling Work Plan.docx 2.0 Final Grade Soil Sampling Scope of Work Final grade soil sampling activities will be conducted at the Site to evaluate the potential for impacts in shallow soil that may pose unacceptable exposure risks to future Site occupants. The soil sampling activities will be performed in general accordance with the DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated July 2021 and the most recent versions of the U.S. Environmental Protection Agency (EPA) Region IV Lab Services and Applied Sciences Division (LSASD) Field Branches Quality System and Technical Procedures guidance. 2.1 Soil Sampling Based on review of the Site Paving Plan, areas of grass, artificial turf, crushed stone, and landscaping will be present at the Site following completion of redevelopment activities. These areas have been divided into five final grade soil evaluation areas (FG-1 through FG-5). H&H proposes to advance three to five shallow soil borings in each of these areas for collection of final grade soil samples (Figure 2). The soil borings will be advanced to a depth of approximately 2 ft below ground surface (bgs) using a decontaminated stainless-steel hand auger. Continuous soil samples will be collected from the center of the hand auger bucket at each boring location. The soil samples will be field screened for the presence of unusual odor, staining, and organic vapors using a photoionization detector (PID). Based on field screening results, one grab soil sample from each of the five evaluation areas will be submitted for laboratory analysis of volatile organic compounds (VOCs) by EPA Method 8260. The VOC samples will be collected from the soil boring within each evaluation area that exhibits the highest likelihood for potential impact. If field screening results do not identify obvious presence of impacts in an aliquot soil sample, the final grade evaluation area grab soil samples will be collected from the 1 to 2 ft bgs sample interval from a randomly selected aliquot soil boring in each evaluation area. In addition, soil samples collected from the borings advanced in each of the five designated areas will be homogenized to form one composite soil sample representative of shallow soil in that area, for a total of five composite final grade soil samples. The composite soil samples will be submitted for laboratory analysis of SVOCs by EPA Method 8270, Resource Conservation and Recovery Act (RCRA) metals by EPA Methods 6020/7471, and hexavalent 4 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/Final Grade Sampling/Work Plan/North Davidson II Final Grade Sampling Work Plan.docx chromium by EPA Method 7199. A final grade soil sample summary is provided as Table 1. The five final grade soil evaluation areas and proposed soil boring locations are shown on Figure 2. The soil samples selected for laboratory analysis will be placed in dedicated laboratory-supplied sample containers, labeled with the sample identification, date, time, requested analysis, and placed in a laboratory-supplied cooler with ice. The samples will be submitted to a North Carolina- certified laboratory under standard chain-of-custody protocols. 2.2 Quality Assurance/Quality Control Non-dedicated equipment and tools will be decontaminated prior to use at each boring location. To evaluate the reproducibility of the sample results, H&H will collect one duplicate soil sample that will be submitted to the laboratory for the same analyses as the parent soil sample. Laboratory quality assurance/quality control (QA/QC) procedures will be employed to ensure appropriate sample handling and analysis and to aid in the review and validation of the analytical data. QA/QC procedures will be conducted in accordance with the method protocols and will include regular equipment maintenance, equipment calibrations, and adherence to specific sample custody and data management procedures. Samples will be analyzed in conjunction with appropriate blanks, laboratory duplicates, continuing calibration standards, surrogate standards, and matrix spiking standards in accordance with approved methodologies to monitor both instrument and analyst performance. H&H will request that the laboratory include estimated concentrations for compounds that are detected at levels above the laboratory method detection limit, but below the laboratory reporting limit (J flags). The laboratory analytical data report and QA package for the final grade soil samples submitted to and analyzed by the subcontracted laboratory will be provided in an appendix to the final report. Laboratory QA data consistent with Level II documentation will be requested for this project. A copy of the completed chain-of-custody record and shipping receipt will be appended to the corresponding laboratory analytical report included with the final report. 5 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/Final Grade Sampling/Work Plan/North Davidson II Final Grade Sampling Work Plan.docx 2.3 Boring Abandonment and Investigation Derived Waste Following sampling activities, the soil borings will be properly abandoned and the surface will be repaired similar to pre-sampling conditions. Investigation derived waste (IDW) generated during the sampling activities will be thin spread on- Site. However, if there is evidence of significant impact (such as free product), the IDW will be containerized in 55-gallon drums and staged on-Site pending analytical results of a composite IDW sample. Based on laboratory analytical results of IDW samples, the drums will be transported off- Site to a suitable facility for disposal. 6 https://harthick.sharepoint.com/sites/MasterFiles-1/Shared Documents/AAA-Master Projects/PAMAKA - PAM/PAM-003 N. Davidson & E. 26th/Final Grade Sampling/Work Plan/North Davidson II Final Grade Sampling Work Plan.docx 3.0 Reporting Following completion of the final grade soil sampling activities and receipt of the analytical data, H&H will prepare a report describing the sampling methods and analytical results. The report will include a description of the sampling activities, figures depicting the sample locations, a tabular summary of the analytical data, a discussion of the data in comparison to regulatory screening levels, risk calculations, laboratory analytical reports including chain-of-custody records, and conclusions based upon our assessment activities.
