I. DESCRIPTION OF PROPOSED INJECTION ACTIVITIES -Provide a briefnarrative regarding the purpose, scope, and goals of the proposed injection activity. In accordance with the Remedial Action Plan for the Site, the purpose of the proposed pilot-scale injection activities will be to evaluate the performance of Plume Stop™ Bioremediation Complex (Regenesis, San Clemente, California) to arrest plume migration toward monitoring wells MW-10 and MW-1 Os and ultimately to mitigate discharge of the plume to the nearby Class C surface water body. A previously-submitted UIC notification (WI0400367) detailed small-scale groundwater injection activities upgradient (enhanced reductive dechlorination, in-situ chemical reduction) and downgradient (aerobic barrier) of the proposed PlumeStop™ pilot test area. The proposed pilot scale activities will involve the injection of PlumeStop™ into the saprolite zone of the surficial aquifer via 6 direct-push (DPT) points and into the partially weathered rock {PWR) zone of the surficial aquifer via 3 permanent injection wells. Three separate intervals will be targeted for injections: shallow saprolite (9-24 ft bgs). deep saprolite (25-35 ft bgs), and PWR (36-41 ft bgs): with a total target volume of approximately 8,325 gallons. Plumestop injections will be performed at a distance of at least 60 feet from the unnamed tributary of Leak Fork as a contingency measure to ensure the release ofinjectate into the water body will not occur. Supporting calculations. previously reviewed by NCDENR. are provided in Appendix A. The pilot test activities may be expanded into other areas of the groundwater plume or supplemented with additional injection activities in the future. Expansion of the proposed injection program or supplemental injection activities may require additional UIC notifications or UIC permit applications. J. IN.JECT ANTS -Provide a MSDS and the following for each injectant. Attach additional sheets if necessary. NOTE: Approved injectants (tracers and remediation additives) can be found online at http://portal.ncdenr.org/weblwq/apsl'lW.,pro. All other substances must be reviewed by the Division of Public Health, Department of Health and Human Services. Contact the UIC Program for more irifo (919-807-6496). Injectant: Plumestop™.

(AECOM) is submitting preliminary calculations and arguments to support ongoing discussion related to the proposed pilot application of the sorptive product Plumestop™ (Regenesis, San Clemente, California) for groundwater remediation at the former RUS facility in Winston-Salem, North Carolina (the Site). These calculations and arguments are presented at the request the North Carolina Department of Natural Resources (NCDENR) following an initial meeting on October 9, 2014 in which you expressed interest in technical justifications for proposed placement of the product near the unnamed tributary of Leak Fork at the Site. AECOM has prepared these calculations using input from Regenesis related to the following key tenants that govern its fate and transport: • Plumestop™ is a colloidal suspension of activated carbon particles and a supporting polymer in water. • Suspensions of Plumestop TM in water are stable predominantly because of electrostatic repulsion between suspended particles that is facilitated by the supporting polymer, which modifies the surface charge of the activated carbon particles and increases repulsion between particles. • Co-deposition of the activated carbon particles and the supporting polymer has been observed in the presence of soluble divalent cations and sorptive mineral surfaces, such as those that are common in silts and clays. AECOM AECOM 701 Corporate Center Drive, Suite 475 Raleigh, North Carolina 27607 tel 919.854.6200 fax 919.854.6259 Using these key tenants, AECOM prepared one calculation based on laboratory data and one calculation based on field data to evaluate the likely transport distance of Plumestop™. Su pp ortin g Calculation 1 AECOM estimated the composition of divalent cations that may be present on the soil exchange complex and calculated the volume of soil required to interact with the proposed amount of Plumestop™ based on a critical cation:Plumestop™ ratio that was suggested by Regenesis. Based on the manufacturer's experience, the critical cation:Plumestop™ ratio has resulted in flocculation of Plumestop TM product in laboratory microcosms. Using the pH of nearby wells MW-10 and MW-10s as a guide, and assuming a relatively low cation exchange capacity of approximately 1 O centimoles per kilogram, AECOM estimated that approximately 15 feet of downgradient transport should be allowed to provide opportunities for Plumestop TM to interact with exchangeable, divalent cations resulting in deposition. This calculation includes a 50% factor-of-safety and does not account for other electrostatic interactions between Plumestop™ and soil surfaces, which are likely very important processes for governing its fate and transport and may reduce the required downgradient travel distance. Su pp ortin g Calculation 2 Data collected by Regenesis during beta testing of the Plumestop TM product indicate that more than 99 percent of suspended Plumestop TM was removed from groundwater approximately 60 days after injections. These data were collected from a monitoring well centrally located within a Plumestop™ injection grid based on 5-feet centers, and in an aquifer where plug-flow flushing cannot account for a significant portion of observed concentration reductions. AECOM used these data to estimate a maximum transport distance over 60 days of saturated, advective flow using Darcy's Law. An estimated radius of influence (ROI) associated with injection under pressure was assumed based on design inputs from Regenesis, and used as the upgradient reference point from which transport associated with saturated flow conditions originates. Applying this logic, a maximum transport distance of 21 feet from the point of injection is estimated for the Plumestop™. The calculations are provided as Calculation 2 in the attachment to this letter. Supporting Argument 1 These calculations suggest that approximately 25 feet of offset should be allowed to facilitate Plumestop TM deposition at the Site. Although AECOM offers these two calculations in good faith based on reasonable assumptions, we would like to reiterate that actual inputs are not known, and that the density of sites available for interaction with Plumestop TM along a tortuous flow path is difficult to model analytically. As an additional measure, AECOM has already permitted and plans to install a barrier of ORC® (also manufactured and marketed by Regenesis) between the proposed Plumestop™ injection barrier and the unnamed tributary. ORC® includes slow-release forms of magnesium, and the manufacturer's bench testing AECOM AECOM tel 919.854.6200 701 Corporate Center Drive, Suite 475 fax 919.854,8259 Raleigh, North Carolina 27607 indicates that it is effective at flocculating PlumestopTM. AECOM's performance monitoring plan for the proposed PlumestopTM injections will also include monitoring of the unnamed tributary for total organic carbon, turbidity, and visible signs of PlumestopTm. if observed, point discharges of PlumestopTM could be mitigated with targeted follow up injections of ORe, ORC-A°, or other flocculating salt. Supporting Argument 2 AECOM is currently working to propose a PlumestopTM injection location that balances the Division's concerns over initial use of the product in the vicinity of the unnamed tributary of Leak Fork with progress towards project milestones that are stipulated in the Remedial Action Plan for the Site. These project milestones are derived from the Administrative Agreement between the State of North Carolina and Cintas Corporation for voluntary remedial action, and include a requirement to achieve remediation of surface water impacts in October, 2017, Therefore placement of PlumestopTM within an estimated one-year travel distance (about 40 feet) would facilitate timely evaluation of the effectiveness, and would leave a minimal amount of time for scale -up of contingent remedies in the event that adequate performance is not observed. AECOM considers this approach to be optimal considering that PCE-impacted groundwater is likely discharging to the unnamed tributary at present, and the proposed PlumestopTM material is relatively benign both in comparison to the regulated constituents and to other viable in -situ remediation products that could be used to address them. AECOM requests the opportunity to review and discuss these calculations and arguments following your review. Please contact Chris Brownfield at (919) 239-7133 if you have any questions.
