An electronic copy of the modification request was submitted via email on October 2, 2018. The original permit was approved on April 16, 2012, renewed on July 22, 2016, and covered installation of an In-Situ Delivery (ISDTM) system and injection of CarBstrateTM for remediation of chlorinated solvent compounds at the former Pro Cleaners (Site or subject Site). The modification request covers connection of the system discharge to the City of Raleigh (City) municipal sewer system to allow for an increase in groundwater treatment volume. Site history and ISDTM system specifications are provided in Section 1.0, groundwater monitoring results and trends related to groundwater remediation efforts are provided in Section 2.0, and details regarding the requested ISDTM system modifications are provided in Section 3.0. 2923 South Tryon Street,Suite 100 3921 Sunset Ridge Rd,Suite 301 Charlotte,NC 28203 Raleigh,NC 27607 www.harthickman.com 704.586.0002 main 919.847.4241 main Mr. Michael Rogers October 2, 2018 Page 2 1.0 Background Information and ISDTM System Specifications The subject Site is located at 8377 Creedmoor Road in Raleigh, North Carolina. The property currently contains Towne North Shopping Center, which is a multi-tenant shopping center. Pro Cleaners operated an active dry-cleaning operation in the tenant space at 8377 Creedmoor Road using tetrachloroethylene (PCE) from an unconfirmed date through 1998. Pro Cleaners currently operates in a different tenant space in the Towne North Shopping Center; however, the current location is a drop-off/pick-up dry-cleaning facility and no dry-cleaning operations have been performed in the new space. The former Pro Cleaners space at 8377 Creedmoor Road is currently occupied by Lux Salon (a hair salon). A release of dry-cleaning solvents was first identified at the Site during a Phase II Environmental Site Assessment (ESA) in 1995. Subsequent assessment activities indicated a plume of groundwater impacted by PCE and PCE breakdown products extending downgradient to the north towards a residential neighborhood across Strickland Road. Historical remedial activities performed at the Site included operation of an air sparge (AS)/soil vapor extraction (SVE) system from 1996 through 2001, excavation of impacted soil in 2007, pilot-scale injection of Anaerobic Biochem Plus Zero Valent IronTM (ABC+TM) in 2009, and beginning in 2013, groundwater remediation through injection of CarBstrateTM via an ISDTM system. The system consists of seven injection wells (IW-lA, IW-2, IW-3, IW-4, IW-5A, IW-6, and IW-7A) and three extraction wells (EW-8, EW-9A, and EW-10). Following extraction, the groundwater is pumped through two granular activated carbon (GAC) AF-500 filters, into a holding tank, then into the ISDTM system where the groundwater is amended with CarBstrateTM on a weekly basis before re-injection into the subsurface. CarBstrateTM is a nutrient-amended carbohydrate substrate that has a high solubility and low-retardation factor. It is a non-toxic, food-grade product that includes the macro-nutrients necessary for effective microbial growth of nitrogen and phosphorous, as well as a specific suite of trace metals that have been shown to be critical for active anaerobic microbial activity. The ISDTM system contains an injection pump, booster pump, solution tank, mixer, metering pump, air-actuated ball valves, flow meters, hart hickman S:\AAA-Master Projects\DSCA-DSO\DSO-130 Pro Cleaners\Remediation\UIC Permit Modification August 2018\DC920001_20181002_UICGroundwaterRemediationPermitModificationRequest.doc SMARTER ENVIRONMENTAL SOLUTIONS Mr. Michael Rogers October 2, 2018 Page 3 compressor, pressure gauges, and a touch screen programmable logic computer (PLC) component that provides a high degree of flexibility in system operation. H&H performs operation and maintenance (O&M) at the Site on an approximate weekly basis. O&M activities include recording flow measurements, amending the extracted groundwater with CarBstrateTM, and monitoring injection pressures and pH of the extracted groundwater. In addition, H&H collects quarterly groundwater samples from locations prior to the working GAC vessel, in-between the working and polishing GAC vessels, and following the polishing GAC vessel to ensure proper treatment of the extracted groundwater. Based on the GAC monitoring, replacement of the carbon has been needed only twice with the most recent change out even occurring in February 2017. 2.0 Groundwater Data Evaluation Since groundwater remediation efforts began in 2009, sampling has been conducted at the Site on a quarterly to semiannual basis. PCE concentrations have reduced substantially since startup of the ISDTM system. Specifically, these reductions can be seen in monitoring wells MW-8B, MW-10B, MW-22S, MW-22D, and MW-23 and extraction wells EW-8 and EW-9/9A. The remaining groundwater impacts are primarily centered around the downgradient property boundary. In addition, a review of groundwater analytical data since project startup indicates increasing trends in monitoring wells MW-5 and MW-1IA. Volatile organic compound (VOC) groundwater analytical data are included in Table 1. A groundwater gradient map and PCE isoconcentration contour map for the May 2018 sampling event are included as Figures 1 and 2, respectively. Samples have also been collected from the downgradient water supply wells on a quarterly to semiannual basis. Low level VOC concentrations have been observed in the water supply well network dating back to initial sampling efforts in the 1990s. Note that water supply wells with VOC concentrations exceeding Title 15A NCAC 2L .0202 Groundwater Standards (2L hart hickman S:\AAA-Master Projects\DSCA-DSO\DSO-130 Pro Cleaners\Remediation\UIC Permit Modification August 2018\DC920001_20181002_UICGroundwaterRemediationPermitModificationRequest.doc SMARTER ENVIRONMENTAL.SOLUTIONS Mr. Michael Rogers October 2, 2018 Page 4 Standards) were properly abandoned. A review of the data for the remaining water supply wells indicates that while VOCs are present at concentrations below 2L Standards, these concentrations appear stable and within historical ranges. VOC groundwater analytical data for these water supply wells are included in Table 2. A water supply well results map for the May 2018 sampling event is included as Figure 3. In addition to the VOC data discussed above, natural attenuation parameters were also collected for select monitoring and water supply wells. The results of this data collection show changes in aquifer conditions in the injection area that are reflective of enhanced reductive dechlorination, including increases or presence of iron, total organic carbon, manganese, and methane and decreases in oxidation reduction potential (ORP), dissolved oxygen, nitrate, and sulfate. However, these changes in aquifer conditions are generally limited to the injection area and no substantial changes in natural attenuation parameters have been measured in the perimeter monitoring wells or downgradient water supply wells. Natural attenuation data are included in Table 3. 3.0 Permit Modification Request As discussed in Section 2.0, the remaining groundwater impacts are primarily centered around the downgradient property boundary. Although groundwater is currently being extracted and treated from this area, the ISDTM system's performance appears to have reached its daily treatment limit. This limitation is driven by constraints on the aquifer's capacity to accept treated groundwater via the injection well network. Currently, the ISDTM system is configured to extract, treat, and inject equal amounts of groundwater as part of a recirculation process. Therefore, in order to increase extraction and treatment volumes to further remediate the PCE plume, H&H is requesting that the groundwater permit be modified to allow for a secondary discharge into the City's municipal sewer system. A secondary discharge will allow the ISDTM system to extract and treat groundwater from the downgradient property boundary without injection restrictions. This modification will also enhance the ISDTM system's ability to maintain hart hickman S:\AAA-Master Projects\DSCA-DSO\DSO-130 Pro Cleaners\Remediation\UIC Permit Modification August 2018\DC920001_20181002_UICGroundwaterRemediationPermitModificationRequest.doc SMARTER ENVIRONMENTAL SOLUTIONS Mr. Michael Rogers October 2, 2018 Page 5 hydraulic control of the PCE plume. Note that this requested modification does not include alterations to the current injection process (i.e. the ISDTM system will continue to inject treated groundwater that has been amended with CarBstrateTM) As part of the sewer system connection process, an Industrial User Permit Application will be submitted to the City's Public Utilities Department. Per conversations between H&H and the City, the volume of discharged groundwater will be tracked with a meter and will not exceed an agreed upon amount to be determined during the application process. In addition, post-treatment groundwater will be sampled prior to discharge into the sewer system. Laboratory analytical results will be provided to the City upon request.
