Morehead Street Charlotte, North Carolina Brownfields Project No. 23031-19-060 H&H Job No. PHL-001 1.0 Introduction On behalf of the Prospective Developer (PD), Panorama Holdings, LLC, Hart & Hickman, PC (H&H) has prepared this In-Situ Soil Sampling Work Plan (Work Plan) to conduct in-situ soil sampling activities at the West Morehead II Brownfields property (Brownfields No. 23031-19- 060) located at 2131, 2211, and 2233 West Morehead Street in Charlotte, Mecklenburg County, North Carolina (Site). The Site is comprised of two contiguous parcels (Mecklenburg County Parcel ID Nos. 06702114 and 06702118) that total approximately 4.68 acres of land. A Site Location Map is provided as Figure 1. Planned redevelopment at the Brownfields property includes demolition of existing buildings, construction of a mixed-use commercial and high-density apartment building (Building 1) in the western portion of the Site, and construction of a high-density residential apartment building (Building 2) in the eastern portion of the Site. The western building will consist of a parking garage along the majority of the ground level and a leasing office, lobby, amenity areas, and utility rooms in the easternmost portion of the ground level. Upper levels will include apartments, a co-working space, commercial units, and a parking garage. The eastern building will be split into two ground-floor levels. Both buildings include open-air parking decks. A figure depicting proposed redevelopment is included as Figure 2. Redevelopment activities including soil export will be performed in accordance with the North Carolina Department of Environmental Quality (DEQ)-approved Environmental Management Plan (EMP) dated November 6, 2023. The DEQ-approved EMP dated November 6, 2023 states that in-situ composite soil sampling may be performed in proposed cut areas at the Site prior to redevelopment. This Work Plan has 2 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc been prepared to detail proposed in-situ soil sampling activities in accordance with the DEQ- approved EMP. The proposed in-situ soil sampling scope of work is provided below. 3 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc 2.0 Scope of Work Due to limited available analytical data for soil in the proposed excavation areas and the lack of space for soil stockpiling, this Work Plan has been prepared to outline a proposed scope of work for conducting in-situ soil assessment activities in areas of proposed cut to characterize soil that may be removed from the Site as part of grading and construction activities. H&H understands that approximately 13,500 cubic yards of soil is anticipated to be generated to achieve proposed final grade elevations. Additional soil will be excavated during construction of the proposed underground stormwater detention systems, a swimming pool, and elevator pits. Much of the proposed cut soil that will be removed is geotechnically unsuitable to use as fill for the proposed structures; therefore, results from the in-situ composite soil sampling activities will be provided to the Brownfields Redevelopment Section and used to determine appropriate off-Site disposal options. It is anticipated that soil excavated from the Site will be either direct-loaded onto trucks for transport or placed on plastic and secured as outlined in the DEQ-approved EMP. The soil will be transported to a Land Clearing and Inert Debris (LCID) landfill, a construction and demolition (C&D) landfill, a municipal solid waste landfill, or a Brownfields property that needs to import fill material. To expedite grading activities and to minimize the need to stockpile and manage large volumes of soil during construction, H&H plans to conduct soil assessment activities at the Site to characterize soil in-situ before grading activities begin. 4 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc 3.0 Sampling Methodology The in-situ soil assessment activities described herein will be performed in general accordance with DEQ Inactive Hazardous Sites Branch (IHSB) Guidelines for Assessment and Cleanup dated September 2023 and the most recent version of the U.S. Environmental Protection Agency Region IV Lab Services and Applied Science Division Field Branches Quality System and Technical Procedures guidance. 3.1 Utility Locating Prior to conducting the field activities, H&H will contact North Carolina 811, the public utility locator service, to mark subsurface utilities at the Site. H&H will also contract with a private utility locator to identify and mark locations of sub-grade utilities in the areas of proposed borings using electromagnetic and ground-penetrating radar methods. In addition, a decontaminated stainless-steel hand auger will be advanced to a depth of approximately 5 feet below ground surface (ft bgs) at each proposed boring location to further screen for potential subsurface utilities. 3.2 Soil Sampling Activities H&H has divided the Site into 19 in-situ soil characterization sections based on the proposed excavation locations and depths at the Site. H&H proposes to collect soil samples for laboratory analysis in each soil characterization section to represent material that may need to be exported off-Site. An in-situ soil sample summary is provided as Table 1. The in-situ soil characterization sections (denoted by “EX” nomenclature) are depicted on Figure 3. H&H will team with a qualified drilling contractor to advance up to five aliquot soil borings in each soil characterization section to depths corresponding to the deepest planned cut in that characterization area. The drilling contractor will initially advance each soil boring with a decontaminated stainless-steel hand auger to depths up to approximately 5 ft bgs. Where 5 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc applicable, a track-mounted direct push technology (DPT) drill rig will be used to advance borings to depths greater than 5 ft bgs. During boring advancement, continuous soil samples will be collected from each boring from the center of the hand auger bucket and/or acetate-lined DPT macrocore sleeves. The soil samples will be logged for lithologic description, inspected for the presence of visual and olfactory indication of potential impacts, and screened for the presence of volatile organic vapors with a calibrated photo-ionization detector (PID). Based on maximum cut depths ranging from 3 to 21 ft, the volume of soil to be characterized by this in-situ assessment is estimated to be approximately 31,400 cubic yards. To characterize this soil, a total of 82 in-situ soil samples (41 grab and 41 composite as described below) will be collected for laboratory analysis. The EMP indicates that to obtain approval for export to a non- permitted receiving facility, a sample frequency of one soil sample for every 1,000 cubic yards of export soil will be required. However, H&H is proposing additional soil samples to provide data that is representative of the 19 soil characterization areas and depth intervals. The approximate volume of disturbed soil represented by each in-situ soil characterization sample is indicated on Figure 3. Please note that Figure 3 shows the volume of soil that would be disturbed if the entirety of each characterization area were excavated to the maximum cut depth for that particular area. Therefore, we propose to conservatively collect samples at a higher frequency than is required by the DEQ-approved EMP. Soil samples from each in-situ soil characterization section will be selected for laboratory analyses as described below. Proposed Cut Areas EX-1 through EX-6 Up to approximately 10 ft of cut is anticipated in sections EX-1 through EX-6 during grading in the western and eastern portions of the Site. H&H proposes to advance 30 soil borings in these six sections (see Figure 3). Each soil boring will be advanced to a depth of approximately 10 ft bgs, and continuous soil sample aliquots will be collected for logging and field screening at 1 to 2 ft intervals from each of the soil borings. Soil sample aliquots from each boring advanced in the section will be homogenized to form composite soil samples representative of soil from 0 to 5 ft bgs and 5 to 10 ft bgs for a total of two composite soil samples [e.g., EX-5 (0-5 ft) and EX-5 (5-10 ft)]. 6 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc Proposed Cut Areas EX-7 through EX-13, EX-15 and EX-16, and EX-18 Up to approximately 5 ft of cut is anticipated in sections EX-7 through EX-13, EX-15, EX-16, and EX-18 during grading in the western and eastern portions of the Site. H&H proposes to advance 50 soil borings in these 10 excavation sections (see Figure 3). Each soil boring will be advanced to a depth of approximately 5 ft bgs, and continuous soil sample aliquots will be collected for logging and field screening at 1.0 to 1.5 ft intervals from each of the soil borings. Soil sample aliquots from each boring advanced in the section will be homogenized to form a composite soil sample representative of soil from 0 to 2.5 ft bgs and 2.5 to 5 ft bgs for a total of two composite soil samples per boring [e.g., EX-7 (0-2.5 ft) and EX-7 (2.5-5 ft)]. Proposed Cut Areas EX-14 Less than 3 ft of cut is anticipated in section EX-14 during grading in the southern portion of the Site. H&H proposes to advance five soil borings in this section (see Figure 3). Each soil boring will be advanced to a depth of approximately 3 ft bgs, and continuous soil sample aliquots will be collected for logging and field screening at 3 ft intervals from each of the soil borings. Soil sample aliquots from each boring advanced in this section will be homogenized to form one composite soil sample [EX-14 (0-3 ft)] representative of soil from 0 to 3 ft bgs. Proposed Cut Area EX-17 Up to approximately 21 ft of cut is anticipated in section EX-17 during construction of an underground stormwater detention area in the eastern portion of the Site. H&H proposes to advance five soil borings in section EX-17 (see Figure 3). Each soil boring aliquot will be advanced to a depth of approximately 21 ft bgs, and continuous soil sample will be collected for logging and field screening at 1 to 2 ft intervals from each of the soil borings. Soil sample aliquots from each boring advanced in the section will be homogenized to form one composite soil sample representative of soil from 0 to 5 ft bgs, 5 to 10 ft bgs, 10 to 15 ft bgs, and 15 to 21 ft bgs for a total of four composite soil samples [EX-17 (0-5 ft), EX-17 (5-10 ft), EX-17 (10-15 ft), and EX-17 (15-21)]. 7 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc Proposed Cut Area EX-19 Up to approximately 17 ft of cut is anticipated in section EX-17 during construction of an underground stormwater detention system in the northeastern portion of the Site. H&H proposes to advance five soil borings in section EX-19 (see Figure 3). Each soil boring will be advanced to a depth of approximately 17 ft bgs, and continuous soil sample aliquots will be collected for logging and field screening at 1 to 2 ft intervals from each of the soil borings. Soil sample aliquots from each boring advanced in this section will be homogenized to form one composite soil sample representative of soil from 0 to 5 ft bgs, 5 to 10 ft bgs, 10 to 15 ft bgs, and 15 to 17 ft bgs for a total of four composite soil samples [EX-17 (0-5 ft), EX-17 (5-10 ft), EX-17 (10-15 ft), and EX-17 (15-17)]. The soil samples will be collected directly into laboratory supplied glassware, labeled with the sample identification, time, and requested analysis, and placed on ice in a laboratory-supplied cooler. The samples will be delivered to a North Carolina-certified laboratory under standard chain of custody protocols. The soil sample locations will be estimated using a hand-held GPS unit. Following soil sampling activities, the soil borings will be properly abandoned with hydrated bentonite, and the ground surface will be restored to approximately match pre-drilling conditions. 8 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc 4.0 Laboratory Analyses The composite soil samples selected for laboratory analyses will be collected directly into dedicated laboratory-supplied sample containers, labeled with the date, time, and sample identification, and placed in a laboratory-supplied sample cooler with ice. The samples will be submitted to a North Carolina-certified laboratory under standard chain-of-custody protocols for 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. In addition to the composite soil samples described above, one representative grab soil sample will be collected from each depth horizon within each soil characterization section for a total of 41 grab samples. Grab samples will be collected from the depth interval and soil boring in each in-situ soil characterization section that exhibits the highest likelihood for potential impacts based on field screening results (i.e., stained soil, elevated PID reading, or odor). If there is no obvious evidence of potential impact in a soil boring based on field screening results, grab samples will be collected from randomly selected soil borings at varying depth intervals to be representative of Site soil. The grab soil samples will be collected from undisturbed portions of soil directly into laboratory supplied glassware, labeled with the sample identification, date, time, and placed in a laboratory- supplied cooler with ice. The grab samples will be submitted to a North Carolina-certified laboratory under standard chain-of-custody protocols for analysis of volatile organic compounds (VOCs) by EPA Method 8260. Laboratory reporting limits for each analyte will be at or below appropriate screening criteria, 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 9 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc quality assurance (QA) package 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 provided 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. 10 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc 5.0 Quality Assurance/Quality Control Non-dedicated equipment and tools will be decontaminated prior to use at each soil boring location and following exposure to soil. For quality assurance and quality control purposes (QA/QC), H&H will collect two duplicate soil samples which will be submitted for the same laboratory analysis as the parent sample to evaluate the reproducibility of sample results. Laboratory 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. 11 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc 6.0 Investigation Derived Waste (IDW) Management IDW comprised primarily of soil cuttings generated during the proposed assessment activities will be managed in general accordance with 15A NCAC 02T.1503. H&H anticipates that soil cuttings will be thin spread on-Site near the sample locations. However, if significant impacts are suspected or observed (i.e., free-product), IDW will be containerized in labeled 55-gallon drums and staged on-Site pending analytical results of composite IDW samples. 12 https://harthick.sharepoint.com/sites/masterfiles-1/shared documents/aaa-master projects/panorama holdings - phl/in-situ soil assessment/work plan/final to deq/revision 1/in-situ soil sampling wp rev 1- west morehead ii (23031-19-060)_2-7-24.doc 7.0 Reporting Following completion of the assessment activities and receipt of the analytical data, H&H will document our findings in an In-Situ Soil Characterization Report. The report will include a title page consistent with the requirements in the Site Assessment Work Plan Checklist, a description of Site activities, rationale for potential deviations from the work plan (if warranted), a figure depicting the sample locations with a redevelopment plan overlay, a tabular summary of the soil analytical data, boring logs, laboratory analytical data, a discussion of the data in comparison to regulatory screening levels, cumulative risk calculations using soil data (if warranted based upon the data), and conclusions and recommendations concerning our activities.
