Home My WebLink About09042 Scott Aviation_final EMP 20200121 1 EMP Version 2, June 2018 NORTH CAROLINA BROWNFIELDS PROGRAM ENVIRONMENTAL MANAGEMENT PLAN This form is to be used to prepare an Environmental Management Plan (EMP) for projects in the North Carolina Brownfields Program at the direction of a Brownfields project manager. The EMP is a typical requirement of a Brownfields Agreement (BFA). Its purpose is to clarify actions to be taken during the demolition and construction at Brownfields properties in an effort to avoid delays in the event of the discovery of new contamination sources or other environmental conditions. The EMP provides a means to document redevelopment plans and environmental data for each applicable environmental medium to inform regulatory-compliant decision-making at the site. As much detail as possible should be included in the EMP, including contingency planning for unknowns. Consult your project manager if you have questions. Prospective Developers and/or their consultants must complete and submit this form and all pertinent attachments, see checklist below, to their Brownfields project manager prior to any earthmoving or other development-related activities that have the potential to disturb soil at the Brownfields Property, including demolition. For the resultant EMP to be valid for use, it must be completed, reviewed by the program, signed by all parties working on the project, and approved by the Brownfields project manager. Failure to comply with the requirements of the EMP could jeopardize project eligibility, or in the event of a completed agreement, be cause for a reopener So that the EMP provides value in protecting brownfields eligibility and public health, the preparer shall ensure that the following steps have been completed prior to submitting the EMP for review. Any EMP prepared without completing these steps is premature. ☐ Site sampling and assessment that meets Brownfields’ objectives is complete and has been reviewed and approved by the Brownfields Project Manager. ☒ Specific redevelopment plans, even if conceptual, have been developed for the project, submitted and reviewed by the Brownfields Project Manager. 2 EMP Version 2, June 2018 Please submit, along with the completed EMP form, the following attachments, as relevant and applicable to the proposed redevelopment: ☒ A set of redevelopment plans, including architectural/engineering plans, if available; if not conceptual plans may suffice if updated when detailed plans are drafted. ☒ A figure overlaying redevelopment plans on a map of the extent of contamination for each media. ☒ Site grading plans that include a cut and fill analysis. ☐ A figure showing the proposed location and depth of impacted soil that would remain on site after construction grading. ☐ Any necessary permits for redevelopment (i.e. demolition, etc.). ☐ A detailed construction schedule that includes timing and phases of construction. ☒ Tabulated data summaries for each impacted media (i.e. soil, groundwater, soil gas, etc.) applicable to the proposed redevelopment. ☒ Figures with the sampling locations and contamination extents for each impacted media applicable to the proposed redevelopment. ☐ A full final grade sampling and analysis plan, if the redevelopment plan is final. ☐ If known, information about each proposed potential borrow soil source, such as aerial photos, historic site maps, historic Sanborn maps, a site history, necessary for brownfields approval. ☐ Information and, analytical data if required, for quarries, or other borrow sources, detailing the type of material proposed for importation to the Brownfields Property. ☐ A work plan for the sampling and analysis of soil to be brought onto the Brownfields Property. Refer to Issue Resolution 15 in Brownfields Program Guidelines. ☐ A map of the Brownfields Property showing the location of soils proposed for export and sampling data from those areas. ☐ If a Vapor Mitigation System is required by the Brownfields Program, the Vapor Intrusion Mitigation System (VIMS) plan will be signed and sealed by a NC Professional Engineer. The VIMS Plan may also be submitted under separate cover. 3 EMP Version 2, June 2018 GENERAL INFORMATION Date: 12/26/2019 Revision Date (if applicable): Click or tap to enter a date.

Parking Lots: located at 316 and 500 West Jefferson Street, 309 West Crowell/316 West Jefferson Street, 502 West Franklin Street and 503 West Jefferson Street/500 West Franklin Street. 2) Check the following activities that will be conducted prior to commencing earth‐moving activities at the site: ☒ Review of historic maps (Sanborn Maps, facility maps) ☐ Conducting geophysical surveys to evaluate the location of suspect UST, fuel lines, utility 5 EMP Version 2, June 2018 lines, etc. ☒ Interviews with employees/former employees/facility managers/neighbors 3) Summary of Redevelopment Plans (MANDATORY: attach detailed plans or conceptual plans, if detailed plans are not available. EMP review without such information would be premature): Provide brief summary of redevelopment plans, including demolition, removal of building slabs/pavement, grading plans and planned construction of new structures: Removal of the building slabs will be conducted subsequent to approval of the EMP. The slabs will be removed with an excavator. Any soil that adheres to the removed concrete will be removed and placed back on the exposed sub-slab soil. However, it is inferred that the slabs are underlain by crushed stone and not in contact with native soil. The removed concrete will be transported off-site for disposal. Removal of the slabs is necessary to allow for a geotechnical study to determine the load bearing capacities of the underlying soils and determine the volumetric calculations for the cut and fill analysis. Scott Figgie, the entity retaining responsibility for the existing impacts at the property (“the RP”), collected soil gas samples beneath the existing slab (to be demolished) in August 2019. Results of that sampling effort are attached. At the RP’s request, additional soil-gas sampling will be conducted by AECOM following slab removal. Removal of the slabs and subsequent soil-gas survey will be necessary to determine if vapor mitigation at the site will be required. If necessary, an engineered vapor mitigation plan would need to be incorporated into the site construction plans. This data will be necessary prior to completion of the A/E drawings necessary for project bid documents and the final version of the EMP. Only minor exterior renovations will be conducted on the Senior Center (former Enquirer Journal building) at 500 West Jefferson Street expansion. No demolition or earth moving are proposed for the Senior Center parcel. The existing former industrial building slabs located at 309 and 310 West Crowell will be removed, prior to site prep work. Each slab will be perforated with a bobcat or equivalent equipment. Pieces of the slab will be removed, inspected and; cleaned, if necessary. Cleaning will be conducted in an appropriate water tight metal or plastic container and the rinseate will be containerized for disposal. Ambient air quality beneath removed slabs will be checked with a PID to ensure safe removal conditions for workers. Only minor grading for storm water runoff will be conducted at each location. Identified impacted soils exceeding were previously removed by excavation in mid-2018 at the 309 West Crowell Street site pursuant to a DEQ-approved EMP. Excavation of identified impacted soils exceeding will be conducted at 310 W. Crowell Street in late-2019 and are to be governed by the Soil Excavation EMP as described above. Once impacted soil removal is completed the property site work will begin on the planned police station and, later, the separate fire station. Any site 6 EMP Version 2, June 2018 work to occur prior to the completion of soil excavation activities will be subject to DEQs approval. However, this EMP contemplates that the soil excavation work will be completed when planned activities occur. The proposed police station will be an approximate 33,000 ft2, 2-story structure on slab with steel construction and will contain offices. The fire station will be a slab mounted, single story steel structure totaling approximately 30,000 ft2. An approximate 3,000 ft2 single story, slab mounted, wash building is proposed in between the 2 larger buildings. Clean fill will be imported to raise the elevation of the police station for security purposes. An estimated 1,200 yd3 of clean fill will be imported to the 310 West Crowell Street property. The 309 West Crowell Street property and the contiguous 316 West Jefferson Street properties will be redeveloped as a parking lot with landscaped areas. The parcels located at 500 W. Franklin Street and 503 W. Jefferson Street will remain as parking lots, but may be upgraded with minor landscaping. Soil and ground water/vapor for the site will be industrial/commercial standards, with the exception of the VIMS plan for the proposed Fire Department Building which will be designed to residential standards. Relevant A/E Plans completed to date are included in Appendix A. The proposed redevelopment map is included in Appendix B. 4) Do plans include demolition of structure(s)?: ☐ Yes ☒ No ☐ Unknown ☐ If yes, please check here to confirm that demolition will be conducted in accordance with applicable legal requirements, including without limitation those related to lead and asbestos abatement that are administered by the Health Hazards Control Unit within the Division of Public Health of the North Carolina Department of Health and Human Services. If available, please provide a copy of your demolition permit. 5) Are sediment and erosion control measures required by federal, state, or local regulations? ☒ Yes ☐ No ☐ Unknown ☒ If yes, please check here to confirm that demolition will be conducted in accordance with applicable legal requirements. If soil disturbance is necessary to install sediment and erosion control measures, they may not begin until this EMP is approved. 6) Which category of risk‐based screening level is used or is anticipated to be specified in the Brownfields Agreement? Note: If children frequent the property, residential screening levels shall be cited in the Brownfields Agreement for comparison purposes. ☒ Residential ☒ Non‐Residential or Industrial/Commercial 7) Schedule for Redevelopment (attach construction schedule): a) Construction start date: 1/2/2020 b) Anticipated duration (specify activities during each phase): 7 EMP Version 2, June 2018 Bid solicitation for site redevelopment is scheduled for December 2019 and bid award scheduled for January 2020. The awarded general contractor will provide a detailed timeline for project completion at that time. The soil excavation activities specified in the Soil Excavation EMP are expected to have a duration of four months and will commence in December 2019. However, some site redevelopment will be conducted concurrently with soil excavation. In particular, slab removal at 309 and 310 West Crowell Street is anticipated to commence in January 2020. The existing slabs will be penetrated and removed and transported to a C&D Landfill for disposal. Following the soil-gas survey in the footprint of the removed slabs, vapor mitigation determination and geotechnical study, the final A/E designs including cut and fill analysis can be completed. The final A/E plans will be incorporated into a construction bid and also submitted to the Brownfields Program manager in the final revision of the EMP. Additionally, remodeling of the Enquirer Journal building into the Senior Center will be initiated. These activities will include the remodeling of the interior of the building, façades and entryway. No cutting or filling of soil will be conducted during the remodeling of the Senior Center. Project duration for the Senior Center buildout is approximately 6 months. Following completion of the planned soil excavation and slab removals at 309 and 310 West Crowell Street, utility trenches will be installed. The 310 West Crowell site will be regraded according to the grading pan. Concrete slab will be poured, utility line extensions completed to the locations of the proposed police and fire stations. Any necessary sub slab or slab vapor mitigation system would also be installed at that time. Perimeter lighting installation would also be completed. Subsequently, the steel of the building will be erected for the police station. Installation of the roofing, HVAC, framing, electrical, plumbing, interior and exterior walls will be installed. If required, an active vapor mitigation system would be installed. This phase is anticipated to be 16 months in duration. Paving and landscaping will be the final stage of the project. These activities are estimated to take 30 days to complete. More detailed timelines for the phases and phase durations will be determined by the awarded contractor. The fire department building will be constructed in a similar phase and duration as the police department building. This phase will be conducted at a later date. Duration of this later phase is estimated at 12 months. c) Additional phases planned? ☐ Yes ☐ No If yes, specify the start date and/or activities if known: 8 EMP Version 2, June 2018 Start Date: TBD Planned Activity: Additional phases are planned; however, the check box above in section c) does not permit editing in this NCDEQ template format.

IMPORTED FILL SOIL NO SOIL MAY BE BROUGHT ONTO THE BROWNFIELDS PROPERTY WITHOUT PRIOR APPROVAL FROM THE BROWNFIELDS PROGRAM. According to the Brownfields IR 15, “Documenting imported soil (by sampling, analysis, and reporting in accordance with review and written approval in advance by the Brownfields Program), will safeguard the liability protections provided by the brownfields agreement and is in the best interest of the prospective developer/property owner.” Requirements for importing fill: 1) Will fill soil be imported to the site?................................................ ☒ Yes ☐ No ☐ Unknown 2) If yes, what is the estimated volume of fill soil to be imported? Limited amount of fill may be required to prepare land and reach grade level during building construction and site renovations. The volume of imported soil is unknown. Once the final grading plan is completed the volume of fill can be estimated. 14 EMP Version 2, June 2018 3) If yes, what is the anticipated depth that fill soil will be placed at the property? (If a range of depths, please list the range.) Approximately 2 feet 4) Provide the source of fill, including: location, site history, nearby environmental concerns, etc. Attach aerial photos, maps, historic Sanborn maps and a borrow source site history: The source of the fill material will be determined by the successful winning bidder. A work plan for sampling the proposed borrow pit will be submitted for NCDEQ review and approval following award of the contract. 5) PRIOR TO ITS PLACEMENT AT THE BROWNFIELDS PROPERTY, provide a plan to analyze fill soil to demonstrate that it meets acceptable standards applicable to the site and can be approved for use at the Brownfields property. Based upon the local barrow pits and quarries in the vicinity of the site, crushed stone imported for fill will likely originate from the Martin Marietta Bakers Quarry in Monroe, NC. Imported soil will likely be acquired from local borrow pit in Monroe, NC. However, the imported soil source will be determined by the GC. A sampling plan for the imported fill facility will be determined after the contract is awarded and the EMP will be updated at that time to identify the source(s) and the sampling plan. Representative samples from the borrow pit will be analyzed by the methods specified below. 6) Please check the applicable chemical analytes for fill soil samples. (Check all that apply): ☒ Volatile organic compounds (VOCs) by EPA Method 8260 ☒ Semi‐volatile organic compounds (SVOCs) by EPA Method 8270 ☒ Metals RCRA List (8) (arsenic, barium, cadmium, chromium, mercury, lead, selenium and silver): Specify Analytical Method Number(s): Click or tap here to enter text. ☐ Pesticides: Specify Analytical Method Number(s): Click or tap here to enter text. ☐ PCBs: Specify Analytical Method Number(s): Click or tap here to enter text. ☐ Other Constituents & Respective Analytical Method(s) (i.e. Hexavalent Chromium, Herbicides, etc.): Click or tap here to enter text. 7) The scope of work for import fill sampling may be provided below or in a Work Plan submitted separately for DEQ review and approval. Attach specific location maps for in-situ borrow sites. If using a quarry, provide information on the type of material to be brought onto the Brownfields Property. If soil is imported from an off-site property or borrow pit that is not a known permitted quarry, a sampling plan will be developed and submitted for DEQ review. DEQ approval of the sampling 15 EMP Version 2, June 2018 plan and analytical results will be obtained prior to transporting import soil the Brownfields property. The borrow pit samples will be analyzed in accordance with the methods specified in item #6 above. However, if the borrow source has not be previously developed (virgin land) soil samples will be collected for the laboratory analysis indicated above at a general rate of 1 per 500 to 1000 cu yds. If the borrow source property has been previous developed, the soil samples will be collected for laboratory analysis indicated above at a general rate of 1 per 400 cu yds. Part 1.C. EXPORTED SOIL NO SOIL MAY LEAVE THE BROWNFIELDS PROPERTY WITHOUT APPROVAL FROM THE BROWNFIELDS PROGRAM. FAILURE TO OBTAIN APPROVAL MAY VIOLATE A BROWNFIELDS AGREEMENT CAUSING A REOPENER OR JEOPARDIZING ELIGIBILITY IN THE PROGRAM, ENDANGERING LIABILITY PROTECTIONS AND MAKING SAID ACTION POSSIBLY SUBJECT TO ENFORCEMENT. JUSTIFICATIONS PROVIDED BELOW MUST BE APPROVED BY THE PROGRAM IN WRITING PRIOR TO COMPLETING TRANSPORT ACTIVITIES. Please refer to Brownfields IR 15 for additional details. 1) If export from a Brownfields Property is anticipated, please provide details regarding the proposed export actions. Volume of exported soil, depths, location from which soil will be excavated on site, related sampling results, etc. Provide a site map with locations of export and sampling results included. Export of soil has not been determined at this time. Removal of the existing slabs and subsequent geotechnical survey will be necessary before any cut and fill analysis can be completed. Once the slabs are removed and the geotechnical study is completed, the EMP will be updated with the cut and fill plan. At this time, it is anticipated that any cut material will be reincorporated into the planned final grade at the site and capped if necessary, to the greatest extent possible. However, any soil deemed necessary to export will be stockpiled on site in roll- off containers. Stockpile soil grab-type samples will be collected from the stockpiled soil and analyzed by the methods specified above for waste characterization and prior to disposal option determination. The soil sampling data will be forwarded to the Brownfields Program manager and the most cost-effective and appropriate disposal options will be presented to the Brownfields Program manager for review and approval. It is anticipated that any export soil will either be transported to another, as yet undetermined, Brownfields facility or to a permitted waste facility based upon the waste characterization. 2) To what type of facility will the export Brownfields soil be sent? ☒ Subtitle D/Municipal Solid Waste Landfill (analytical program to be determined by landfill) ☒ Permitted but Unlined Landfill (i.e. LCID, C&D, etc.) Analytical program to be determined by the accepting Landfill; ☐ Landfarm or other treatment facility ☒ Use as fill at another suitable Brownfields Property – determination that a 16 EMP Version 2, June 2018 site is suitable will require, at a minimum, that similar concentrations of the same or similar contaminants already exist at both sites, use of impacted soil will not increase the potential for risk to human health and the environment at the receiving Brownfields property, and that a record of the acceptance of such soil from the property owner of the receiving site is provided to Brownfields. Please provide additional details below. ☐ Use as Beneficial Fill off-site at a non-Brownfields Property - Please provide documentation of approval from the property owner for receipt of fill material. This will also require approval by the DEQ Solid Waste Section. Additional information is provided in IR 15. Please provide additional details below. 3) Additional Details: (if transfer of soil to another property is requested above, please provide details related to the proposed plans). This option will be studied once the cut and fill plan has been completed and submitted to the Brownfields Program manager in an updated EMP.
