To increase predictability and most efficiently assess Brownfields Properties and the redevelopment timing requirements of Prospective Developers or follow-on owners, the Brownfields Redevelopment Section has standardized the format for Site Assessments. This format has been generated in the form of a checklist to allow for ease in submission by the prospective developer’s consultant and for the Brownfields Redevelopment Section’s completeness review. This checklist outlines the minimum requirements and submittal format under the Brownfields Redevelopment Section for Assessment Requirements and Reporting. All Assessment Work Plans and Report submissions to the Brownfields Redevelopment Section must include this completed checklist in the outlined format. These requirements allow DEQ to reduce review time for the Assessment Work Plan and Report and increase process predictability for prospective developers. This checklist will also provide reliable data for risk-based decisions and further expedite the project timeline. Any divergence from these requirements will lengthen the process of assessing risks on the site, may necessitate reprioritization of a project manager’s queue towards projects that meet these requirements. Therefore, delaying production of the brownfields agreement and/or environmental management plan. Any alterations to the checklist on a site-specific basis must be reviewed and approved by the Section prior to implementation. However, in order to respect the schedule of all projects in house and keep the Section’s entire project pipeline moving, we strongly recommend against seeking changes to the checklist. Based on a review of environmental and risk data from our project inventory, please note there are some new points of emphasis that are included herein: 1. For ALL residential reuses; sub-slab vapor assessment (full list EPA TO-15) is required, regardless if existing structures will be removed. If no structures or slabs exist on the Brownfields Property, exterior soil gas assessment is required within all proposed structure footprints.  2. ALL properties require groundwater data (VOCs, SVOCs and RCRA Metals) from a minimum of three sample locations, depth to groundwater and a resulting potentiometric map.  3. Soil shall be assessed based on areas of concern and redevelopment plans and across the depth interval of the cut/grading.

(H&H) has prepared this Final Grade Soil Assessment Work Plan (Work Plan) for the Crayton Printing Brownfields property (Brownfields Project No. 24025-20-060) located south of the Distribution Street and Dunavant Street intersection in Charlotte, Mecklenburg County, North Carolina (Site). The Site consists of one approximate 2.85-acre parcel of land (Mecklenburg County Parcel Identification No. 12104201) located in a mixed commercial and residential use area of South End Charlotte. A Site location map is provided as Figure 1, and the Site and surrounding area are shown in Figure 2. A Brownfields Agreement between the North Carolina Department of Environmental Quality (DEQ) and the PD was recorded on October 1, 2021. The Land Use Restriction (LUR) 12.f. of the Brownfields Agreement generally states that no occupancy of the Brownfields property may occur after redevelopment until representative final grade soil samples have been collected in areas at the Site that are not covered by building foundations, sidewalks, or asphalt or concrete parking areas and driveways (hardscape). The Brownfields Agreement also generally states that physical redevelopment of the Site will be completed in accordance with a DEQ-approved Environmental Management Plan (EMP). The EMP prepared for the Crayton Printing redevelopment received DEQ approval on December 8, 2020. In accordance with the DEQ-approved EMP and LUR 12.f. of the recorded Brownfields Agreement, final grade soil sampling will be conducted at the Site in areas that are not covered with building foundations, sidewalks, or asphalt or concrete parking areas and driveways following completion of redevelopment activities that disturb soil. Redevelopment of the Site 2 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/akridge/akr.005 dunavant brownfields assessment/final grade/work plan/24025 - crayton printing - fg soil assessment work plan.doc included razing the former Site buildings for the construction of a high-density apartment building with an associated parking deck known as Hawkins Press. A Required Overall Planting Plan prepared by Land Design depicting the redevelopment and landscaping plan is provided as Appendix A. The proposed final grade soil assessment scope of work is provided in the following sections. 3 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/akridge/akr.005 dunavant brownfields assessment/final grade/work plan/24025 - crayton printing - fg soil assessment work plan.doc 2.0 Final Grade Assessment Activities The soil assessment activities described herein will be conducted in general accordance with the DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup of Contaminated Sites (Guidelines) dated September 2022, the most recent versions of U.S. Environmental Protection Agency (EPA) Region IV Laboratory Services and Applied Science Division (LSASD) Field Branches Quality System and Technical Procedures guidance, and the DEQ Brownfields Minimum Requirements Checklist for Site Assessment Work Plans and Reports dated March 2023. The purpose of the final grade soil assessment activities is to evaluate potential direct exposure risks to future Site occupants and workers from shallow soil in landscaped areas at the Site. A description of the final grade soil assessment activities is provided in the following sections. 2.1 Final Grade Soil Sampling Activities Based on review of the Required Overall Planting Plan, observations at the Site, and communications with the PD, landscaped areas at the Site have been identified and divided into four (4) final grade evaluation areas (FG-1 through FG-4). To evaluate soil within each final grade evaluation area, five (5) shallow soil borings will be advanced in each area for the collection of aliquot soil samples. The final grade evaluation areas and approximate locations of the aliquot soil boring locations are shown in Figure 3. Aliquot soil borings will be advanced from the surface to approximately two (2) feet below ground surface (ft bgs) using a decontaminated stainless-steel hand auger. During boring advancement, continuous soil samples will be collected from the center of the hand auger bucket. Soil samples will be described for lithologic purposes and observed for obvious evidence of staining and unusual odors. A portion of the soil sample from each aliquot location will be allowed to volatilize and will be field screened for the presence of volatile organic vapors using a calibrated photoionization detector (PID). 4 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/akridge/akr.005 dunavant brownfields assessment/final grade/work plan/24025 - crayton printing - fg soil assessment work plan.doc Remaining portions of the aliquot soil samples will be homogenized to form a composite soil sample representative of shallow soil in each evaluation area. Composite soil samples will be submitted for laboratory analysis of semi-volatile organic compounds (SVOCs) by EPA Method 8270 and Resource Conservation and Recovery Act (RCRA) metals plus hexavalent chromium by EPA Methods 6020/7471/7199. Based on results of field screening, a grab soil sample from an undisturbed portion of the aliquot location exhibiting the highest likelihood for impact will be collected from each of the final grade evaluation areas and will be submitted for laboratory analysis of volatile organic compounds (VOCs) by EPA Method 8260. If field screening results do not identify the obvious presence of impacts in an aliquot soil sample within an evaluation area, the final grade evaluation area grab sample will be collected from the 1 to 2 ft bgs sample interval from a randomly selected aliquot soil boring in each evaluation area. Soil samples selected for laboratory analysis will be collected directly into laboratory supplied glassware; labeled with the sample identification, date, and requested analysis; and placed in a laboratory supplied cooler with ice. The sample cooler will be submitted to a North Carolina certified laboratory under standard chain of custody protocols. A final grade soil sample summary is provided as Table 1. Following sampling activities, the soil borings will be abandoned and the surfaces will be repaired similar to pre-drilling conditions. In addition, the soil sample locations will be estimated using a hand-held global positioning system (GPS) unit. 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 (1) duplicate soil sample as part of the final grade sampling. The duplicate sample will be submitted for the same analyses as the parent soil sample. 5 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/akridge/akr.005 dunavant brownfields assessment/final grade/work plan/24025 - crayton printing - fg soil assessment work plan.doc 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 calibration, 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 laboratory method detection limits for each analyte be at or below the DEQ Residential Preliminary Soil Remediation Goals (PSRGs), where possible. Additionally, 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 and will be included with the final report. 2.3 Investigation Derived Waste Based on results of previous soil assessment completed at the Site, investigation derived waste (IDW) generated during the assessment activities will be thin spread on-Site. However, if significant impacts are suspected based on field screening results (i.e., presence of free product, etc.), the soil cuttings 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 sample (if collected), the IDW will be managed in general accordance with DEQ IHSB 15A NCAC 02T.1503 and 15A NCAC 02H. 0106 rules. 6 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/akridge/akr.005 dunavant brownfields assessment/final grade/work plan/24025 - crayton printing - fg soil assessment work plan.doc 3.0 Reporting Following completion of the assessment activities and receipt of the laboratory analytical data, H&H will prepare a Final Grade Soil Assessment Report. The report will include a description of field activities, field screening results, a tabular summary of the analytical results in comparison to regulatory screening levels, risk calculations, boring logs in tabular form (will include boring IDs, field screening/PID results, and soil descriptions), figures depicting the sample locations, laboratory analytical reports and chain of custody records, a discussion of QA/QC data, and conclusions and recommendations based upon our assessment activities. The report will be sealed by a North Carolina Professional Engineer (PE) or Professional Geologist (PG) and the firm PE/PG numbers will be provided.
