PO Box 4529 High Point, North Carolina 27263 Subject: NPDES Permit Issuance Permit No. NC0086029 Trinity American Corp. Randolph County Dear Mr. Drye: Division staff have reviewed and approved your application for an NPDES discharge permit. Accordingly, the Division is forwarding the subject NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated May 9, 1994 (or as subsequently amended). The following items appear in this FINAL permit: • Change in the chronic toxicity sample type from composite to grab, based on the fact that the treated effluent is not discharged continuously. • Addition of a monthly average flow limit of 0.072 MGD, based on the treatment plant design capacity. • Please note that the updated toxicity test language includes specific procedures to be followed in case of a toxicity test failure, including follow-up monthly multiple concentration testing. • Please note that this facility discharges to Caraway Creek, which provides habitat for several sensitive freshwater mussels. Therefore, continued compliance with permit limits is critical. This NPDES permit requires the permittee to take all reasonable steps to mitigate any discharge in violation of this permit which has a reasonable likelihood of adversely affecting human health or the environment (refer to Part II, Section B.2, Duty to Mitigate). In addition, the permittee is required to at all times properly operate and maintain the groundwater remediation system (refer to Part II, Section C.2, Proper Operation and Maintenance). • Change the permit expiration date to 1/31/04. If any parts, measurement frequencies, or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the office of Administrative Hearings, 6714 Mail Service Center, Raleigh, North Carolina 27699- 6714. Unless such a demand is made, this permit shall be final and binding. Please take notice that this permit is not transferable except after notice to the Division. Part II, E.4. addresses the requirements to be followed in case of change in ownership or control of this discharge. The Division may require modification or revocation and reissuance of the permit. This permit does not affect the legal requirements to obtain other permits which may N.C.Division of Water Quality/NPDES Unit Phone:(919)733-5083 1617 Mail Service Center,Raleigh,NC 27699-1617 fax:(919)733-0719 Internet:h2o.enr.state.nc.us DENR Customer Service Center. 1 800 623-7748 • C�g6 Cominei1 117 I (1 i . t CD opir e, N \ Otifitf oo CD North Carolina Wildlife Resources Commission : ' - Charles R.Fullwood,Executive Director MEMORANDUM TO: Tom Belnick, NPDES Unit Division of Water Quality FROM: Danielle R. Pender, Piedmont Region Coordinator Habitat Conservation Program DATE: 25 October 2001 SUBJECT: Proposed Permit Renewal for Trinity American Corporation,Randolph County NPDES Permit No. NC0086029 Biologists with the North Carolina Wildlife Resources Commission have reviewed the subject application for impacts to fish and wildlife. Our comments are provided in accordance with provisions of the Clean Water Act of 1977 (as amended), the Fish and Wildlife Coordination Act (48 Stat. 401, as amended; 16 U.S.C. 661-667d), and North Carolina General Statutes (G.S. 113-131 et seq.). Trinity American Corporation has submitted a request for a permit renewal to discharge 0.072 MGD of treated groundwater to Caraway Creek in the Yadkin-Pee Dee River Basin. The groundwater contains several toxic organic solvents and will be treated utilizing air stripping and carbon filters. The facility discharges to an onsite pond, which overflows into an unnamed tributary of Caraway Creek. Monthly effluent data for the past 18 months have shown no detection for the four monitored solvents and quarterly chronic toxicity test results have passed 12 of 12 events. As we indicated in earlier comments on this permit (Anderson, 29 September 1997), Caraway Creek provides habitat for several freshwater mussels. Species known to occur in this stream include the federal species of concern and state threatened, brook floater(Alasmidonta varicosa) and Atlantic pigtoe (Fusconaia masoni), the federal species of concern and state special concern, Carolina creekshell (Villosa vaughaniana), the state threatened, creeper (Strophitus undulatus), the significantly rare, Eastern creekshell (Villosa delumbis) and notched Mailing Address: Division of Inland Fisheries • 1721 Mail Service Center• Raleigh,NC 27699-1721 Telephone: (919) 733-3633 ext.281 • Fax: (919) 715-7643 • Page 2 25 October 2001 Trinity American Corporation NPDES No.NC0086029 rainbow(Villosa constricta). In addition, another sensitive mussel species, Eastern elliptio (Elliptio complanata)has been found in this creek. Mussels are filter feeders and can bioaccumulate toxic substances. We would not expect groundwater discharge that has been passed through activated carbon filters to adversely impact the aquatic habitat of Caraway Creek. However, any malfunction in the treatment system that would allow toxic substances to pass downstream could have significant adverse impacts to threatened and rare species. We offer the following comments and recommendations to reduce impacts to fish and wildlife resources and in particular to listed species. 1. We are pleased that the applicant has routinely passed toxicity tests. However, we continue to request that the applicant cease discharge upon any single violation of a water quality standard or the failure of a single toxicity test and to relocate the discharge out of Caraway Creek. 2. Notify our office of violations of any water quality standard by this applicant. We appreciate the opportunity to comment on this permit notice and your efforts to help protect this important habitat in Caraway Creek.

EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS. It is requested that the quarterly chronic toxicity monitoring be collected as a grab sample, rather than as a composite sample. The groundwater recovery wells that are the source of the treated effluent discharge do not pump continuously. Rather they pump in a random configuration based on groundwater drawdown and recovery levels. The treatment system operates as a closed system, with access via spigots for system monitoring purposes. The discharge pipe to the fire protection pond is under water. WSRO DWQ personnel have confirmed these conditions through an on site evaluation (April 2001), and have concurred that grab sampling is the only available option for this system. These grab samples are representative of the discharge. Also, please note that the effluent sample collection point has changed from the pond overflow discharge pipe to the effluent directly from the groundwater treatment system. Permission to modify this sampling location was obtained from the WSRO. The change was requested in order to avoid impact from a heating oil release that occurred in the immediate vicinity of the previous discharge point. ._ .

NPDES PERMIT FACT SHEET Trinity American Corporation Page 2 NPDES No. NC0086029 PROJECT NOTES Snmmarq • This is a minor permit renewal for an existing 0.072 MGD groundwater treatment system utilizing air stripping and carbon filters to remove solvent contaminants prior to surface water discharge. The treatment system is fairly new, being originally permitted in December 1997. Monthly effluent data for the past 18 months (1/00-6/01) have shown no detections (all <1 ug/1) for the four monitored solvents. In addition, quarterly chronic toxicity test results have passed 12 of 12 events. Thus, effluent data shows that the treatment system is performing satisfactorily, and not expected to adversely impact the aquatic habitat. • The facility discharges to an onsite fire protection pond which overflows to an unnamed tributary to Caraway Creek in the Yadkin Pee Dee River Basin (Note: the previous permit incorrectly identified the basin as the Cape Fear). The receiving stream is considered zero- flow, is not 303(d) listed, and has no specific management strategies. During the last permit cycle, the NC WRC noted that Caraway Creek provides habitat for several freshwater mussels, which are state-listed threatened, special concern, or significantly rare. • A monthly average flow limit of 0.072 MGD has been inserted in this draft permit, based on the design capacity of the treatment system. The facility's actual discharge has been averaging 0.018 MGD. • The permittee submitted their NPDES permit renewal application (Short Form C-GW) on 10/16/00. The current permit expired on 8/31/01. NPDES recommends renewal of the current permit with the changes noted above.

An examination of the Cape Fear basin plan and the NPDES permit schedule has revealed that the existing expiration dates in Cape Fear NPDES permits do not coincide with the revised permit expiration dates for the basin. This discrepancy could create unnecessary delays in the processing of over 200 permit renewals. Accordingly,the Division is changing the permit expiration dates for NPDES permits in the Cape Fear river basin. This permit modification changes the expiration date of the subject permit in subbasin 30608 to August 31,2001. Please find enclosed the revised permit cover page. Insert the new cover page into your permit and discard the old page. All other terms and conditions contained in the original permit remain unchanged and in full effect. This permit modification is issued under the requirements of North Carolina General Statutes 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.Environmental Protection Agency. In accordance with the modification of the permit expiration date,the new due date for your renewal application is March 4,2001. Renewal application forms will be sent to you approximately 6-8 weeks in advance of the new due date or you may download the forms from the NPDES web site at http://h2o.enr.state.nc.us/NPDES/documents.html. You will need to download Short Form C-GW. If you have already submitted a permit renewal form,there is no need to submit any other forms to the Division;the application will be processed during the renewal period for your subbasin. If any part of this permit modification are unacceptable to you,you have the right to an adjudicatory hearing upon written request within thirty(30) days following receipt of this letter. This request must be a written petition conforming to Chapter 150B of the North Carolina General Statutes,filed with the Office of Administrative Hearings(6714 Mail Service Center,Raleigh,North Carolina 27699-6714).

BACKGROUND Four major phases of site assessment activities have been conducted at the TAC facility. Those phases are: 1. Fuel oil underground storage tank (UST) removal and soil sampling; 2. Phase I and Phase II environmental site assessments (ESAs) ' conducted by Trigon Engineering Consultants, Inc.; 1 3. A Comprehensive Site Assessment conducted by ENSCI Environmental, Inc.; and, 1 4. Amendments to the Comprehensive Site Assessment by Cooper Environmental, Inc. (CEI). ' The data collected during these investigations indicated that a former (TPI) solid waste landfill appears to be the source of Thomasville Products, Inc.Inc• PP groundwater impact at the site. The parameters of concern are primarily chlorinated hydrocarbons. Table 1 shows the historical groundwater analytical data for water samples collected from supply wells nearby the site. Table 2 shows the analytical data for groundwater samples collected from monitoring wells at the site. Figure 2 is a site map showing the locations of the sampled wells. S S I . I In November 1995, a Corrective Action Plan (CAP) was submitted to the • Winston-Salem Regional Office (WSRO) of the NCDEHNR. This plan outlined the remedial strategy for the site and proposed soil and groundwater remedial alternatives. Correspondence from NCDEHNR dated December 18, 1996 ' notified Trinity that the proposed CAP was `considered acceptable' and that public notice would proceed on December 26, 1996. Implementation of the CAP is included as a requirement in the Special Order by Consent (SOC) EMC f #AQ 95-09. The selected remedial alternative is groundwater extraction followed by treatment and subsequent discharge to surface waters. An in-situ air sparging ' system is also proposed for the site to complement the groundwater extraction remediation system. The purpose of this permit application is to obtain a ' National Pollutant Discharge Elimination System (NPDES) Permit for the ' discharge of the treated water from the proposed groundwater extraction and treatment system. 3. WASTEWATER CHARACTERIZATION Table 1 displays the historical analytical results for water samples collected from supply wells nearby the site. Table 2 shows the analytical data for groundwater samples collected from monitoring well at the site. Table 3 shows the design influent concentrations for the treatment system as ' calculated based upon worst case well concentrations over the previous 24 month period. Actual influent concentrations are anticipated to be much lower than the design values. ag The average wastewater flow rate for the system is approximated as 35 gallons per minute (gpm). A design flow rate for the ' treatment system of 50 gpm was utilized to provide added safety and to account for instantaneous flow rate fluctuations. 1 2 w I . i 4. REMEDIATION SYSTEM SPECIFICATIONS I 4.1. Groundwater 1____________ It Ira dissolved-phase chlorinated hydrocarbons will Groundwater containing P i be recovered utilizing seven (7) recovery wells equipped with total fluids submersible pumps. Six shallow recovery wells, completed to approximately s 35 feet below ground surface, will be equipped with 1/2 horse power (HP) I pumps with the capacity topum upto 5 gpm at the expected hydraulic P V' supply. well, DW-7, will be used to recover Ipressures. An existing groundwater at approximately 120 feet below ground surface. This well will be equipped with a 3/4 horse power (HP) pump with the capacity to pump up to 10 I gpm at the expected hydraulic pressures. Each recovery well will have an in- i line flow meter prior to the treatment system. Design calculations for the recovery system are included as Appendix A. Figure 3 shows the proposed Ilocations for the recovery wells at the site. 4.2. Treatment Svstem I pumped to a treatment system consisting *_ Recovered groundwater will be of a transfer tank, a tray aeration unit, and granular activated carbon. Figure e , 4 shows the conceptual treatment system schematic. The groundwater will be Ipumped to a transfer tank which will also serve as a flow equalization to From there, the groundwater will bepumped through a particulate filter Itop of the tray aeration unit. The groundwater will flow by gravity through the ,,,R tray aeration unit. The aeration unit is designed to have an air to water ratio oaf rat least 89:1 to provide for removal of volatile chlorinated hydrocarbonsv ndor it stripping. Appendix B contains design calculations provided oundwrtof of the proposed aeration unit. From the aeration unit, the treated gr will be pumped through carbon to the proposed discharge location. The 3) is a small pond located on the TAC proposed discharge location (see Figure r- property which discharge to an unnamed tributary of Caraway Creek. ,: 3 I . . F4 1 Sampling ports will be provided at strategic points along the treatment system so that the effectiveness of the remediation system can be monitored as 1 .- needed. Sampling ports will be installed at each recovery well, and before and after the aeration and carbon units. The treatment system contains numerous fail-safe measures designed to protect the environment in the event of an emergency condition. The fail-safe measures include: • check valves placed in-line for each recovery well to prevent • backflow into the well; r- . a high-level switch in the transfer tank that prevents overfilling by shutting off the recovery wells in the event of a high-level condition; I . a pressure switch on the tray aeration unit to shut the system down 1 • in the event of aeration blower failure; and, • a high-level switch in the tray aeration unit to shut the system down in the event of a high-level condition in the tray aeration 1 sump. 5. ALTERNATIVE DISCHARGE OPTIONS Alternative discharge options for the site were investigated by Marziano gy Minier, P.A. Consulting Engineers in relation to the facility's sanitary wastewater. A copy of their report entitled 'Evaluation of Wastewater Disposal Iendix C. During that Alternative? dated March 15, 1996 is included as App evaluation it was found that there is no regional sewer within 2 miles of the site ' and that subsurface disposal, spray irrigation, and wastewater treatment and reuse were not viable options. The flow rate utilized for that' evaluationwat s gallons per day. The flow rate anticipated for the ground 2,500 remediation system is 35 gallons per minute, which is equivalent to 50,400 nf ormation, the only viable discharge option gallons per day. Based upon this i 1 Ttr4 1 1 . for the treated groundwater is discharge to surface waters under an NPDES ' permit. P. ' 6. EVALUATION OF CORRECTIVE ACTION ALTERNATIVES The following sections describe the remedial alternatives considered, and ' the rationale for the technology selected. The sections also detail the implementation, operation, and life cycle cost estimate for the selected technology. ' 6.1. Remedial Techniques Considered CEI considered the following remedial options. A summary of the 111 different remedial options considered and their associated estimated life-cycle cost is contained in Table 4. 6.1.1. Monitoring Only ' A risk assessment and associated long term monitoring only remedial option was considered to be inappropriate for this site at this time given the ' concentrations of dissolved halogenated VOCs currently on-site. 6.1.2. Groundwater Withdrawal CEI considered this technique to be an effective means for providing hydraulic control over the dissolved plume and removing dissolved phase VOCs from the subsurface. Treatment options for the pumped water were considered ' on a life-cycle cost basis. A summary of the different ex-situ groundwater „. treatment options and their associated life-cycle estimated cost is included in Table 3. 6.1.3. In-situ Air Sparge This option was considered viable only in combination with groundwater extraction, since in-situ air sparge does not exert hydraulic control by itself. T' I 5 I 6.1.4. In-situ Bioremediation This option was considered technically feasible for the bioremediation of dissolved VOCs using indigenous naturally occurring bacteria. The reaction rate of in-situ bioremediation eliminated this option from further consideration. Based on the preliminary cost estimates and technical feasibility considerations of the available technologies, CEI chose to further investigate the applicability of groundwater extraction and air sparging. 6.2. Pilot Tests The following sub-sections describe pilot testing of groundwater extraction and air sparging. 6.2.1. Pump Test On November 20, 1995, CEI personnel conducted a pump test on recovery well RW-2. This well was installed on November 17, 1995 by McCall Brothers of Charlotte, North Carolina under the supervision of CEI personnel. ' RW-2 is constructed of 6-inch diameter PVC well casing to a depth of approximately 30 feet below grade. The screened interval is constructed of ' 0.020-inch circumslot PVC extending from 10 feet to 30 feet below grade. Groundwater was removed from RW-2 at the rate of approximately 3.5 gallons per minute for approximately 10 hours. During the pump test, depth to water measurements were recorded automatically by a datalogger probe placed in the recovery well and in well EW-1 (see Figure 2). A summary of the data recorded from the pump test is contained in Appendix D. 6.2.2. Air Sparging Pilot Study ' CEI conducted an in-situ air sparging test at the TAC site on November 16, 1996. Monitoring well EW-1 was selected as the sparge well since the top of the water table was approximately 8 feet higher than the top of the sand �• filter pack in that well. CEI forced clean filtered air into EW-1 for ler approximately 65 minutes. During the test, depth to water and dissolved 6 r O I oxygen measurements were recorded in wells PZ-1, EW-3, RW-1, VE-1 and tEW-2 (Figure 2). Air flow delivered and pressure at the wellhead of EW-1 were f.• also recorded. The results of the test are summarized in Appendix E. Air flow into the well was initiated at a pressure of approximately 2 pounds per square inch (PSI) greater than that necessary to remove water from the casing. A pressure of approximately 15 PSI resulted in an air flow rate of approximately 1.4 cubic feet per minute (CFM). A rise in the water table was observed in the measured monitoring wells during the test. Dissolved oxygen measurement • remained relatively constant during the test. CEI estimated the radius of ' influence of the sparge test as approximately 100 feet. The radius of influence could potentially be increased by deepening the screened interval of the sparing well and increasing the air flow rate. 1 6.3. Alternative Treatment Techniques I CEI investigated the potential use of the following treatment techniques for the extracted groundwater: 6.3.1. Air Stripping Air stripping involves the volatilization of contaminants from the groundwater by any one of several methods of introducing air to the II` groundwater influent stream. The methods include: counter-current packed towers, low-profile 'tray' aerators, and diffused aeration tanks. These volatili'ation methods are applicable to the TAC site. Of these methods, a low- profile tray aerator provides the most reliable operation under all weather conditions and is deemed most appropriate for the site. 6.3.2. Ultraviolet Light (UV) and Ozonation UV and ozonation involve sparging the influent groundwater with ozone and then exposing the groundwater to ultraviolet light. This combination treatment results in oxidation of the organic contaminants. This technique is not commonly used in North Carolina for the treatment of groundwater because it 7 I I . turbidity which interfere occurring inorganic contaminants and tur ty of naturally o g rwith the process. This technique is not considered applicable for the r• referenced site. r6.3.3. Ex-situ Bioremediation iEx-situ bioremediation involves adding bacteria and nutrients to the groundwater influent stream in a bioreactor to allow the bacteria to break down the organic contaminants. This technique was not considered applicable for r• the referenced site because of the potential otential intensive operation and 1 maintenance requirements of the technique and because of the concern about F- the potential end products of incomplete biological degradation. r6.3.4. Carbon Adsorption I Carbon adsorption involves passing the extracted groundwater througha , beds of activated carbon which sorb the organic contaminants onto the carbon Ithus removing them from the wastewater. Carbon adsorption is proposed for use at the TAC site as a polishing step to the tray aeration process. r 7. GROUNDWATER TREATMENT SYSTEM DESIGN The following subsections describe the design components for the system 1 to be installed at the site. 7.1. Groundwater Withdrawal Figure 3 shows the proposed location of the recovery wells for the site. 111 CEI proposed the use of 6 shallow recovery wells (RW-1 through RW-6) and groundwater at the site. Groundwater deep recovery well (DW-7) to recovery Irecovery will be by environmental submersible pumps manufactured by Grundfos Pumps, Inc. Pipe and pump sizing calculations are contained in Appendix A. Pump performance curves are contained in Appendix F. Pipe I l,' trenches are proposed to be located as shown in Figure 5 and constructed as Ishown in Figure 6. t. 8 A i 7.2. Groundwater Treatment Groundwater treatment will be by aeration in a low-profile air stripper. The low profile air stripper selected is the Shallow Tray 2631 or equal. The idesign parameters for the aeration unit are presented in Table 2. Appendix B contains the stripper vendor's design calculations. Table 2 shows the proposed effluent discharge limitations. 1 Based on data from the pump test on November 20, 1995, CEI anticipates maximum individual well flow for recovery wells RW-1 through RW- ' 6 to be less than 5 gpm and for DW-7 the estimated flow rate is 10 gpm. The design flow rate includes additional flow for an added safety factor. Following treatment in the tray aeration unit, the water will be pumped through a set of carbon vessels in series. Each individual unit of the series will contain at least 500 lbs of carbon. The carbon will be utilized as a polishing step. 7.3. Discharge Of Treated Water After treatment of the water by the tray aeration unit, the water will be 111 discharged to a pond located on the TAC property (Figure 2). The pond discharges to an unnamed tributary of Caraway Creek. This discharge location } is the closest point suitable for the discharge of a non-oxygen consuming ' wastewater and will allow for the quickest implementation of groundwater 1 remediation at the site. tr 8. MONITORING OF SYSTEM PERFORMANCE The following sections outline the proposed schedule for monitoring the performance of the remedial system. s I yr I ;.r 9 Ara • j i 8.1. Baseline Monitoring Prior to system start-up, water level data be collected from each of the project monitoring wells. Dissolved oxygen and pH levels in the groundwater ' from select wells will be measured and recorded. ' 8.2. System Start-Up and Operation The groundwater remediation system will be activated. All meter and ' readingswill be collected and recorded. It is proposed to begin operation gauge i of the groundwater extraction system at 50% of the design flow and to increase the flow rate in a stepwise manner after demonstrating the treatment system achieves the required level of treatment. Influent samples will also be collected to document treatment system efficiency and contributions from the various recovery wells. In addition, water samples will be collected before and after carbon treatment to verify performance of the carbon treatment unit. 8.3. System Monitoring During the first month of operation, the system will be inspected on a weekly basis. Water level data and system gauge and meter readings will be ' collected and recorded. Dissolved oxygen and pH levels in the groundwater will be measured and recorded in select wells as needed. Following the first month of operation, the remediation system will be inspected on a monthly basis. Water level data and system gauge and meter readings will be recorded during each visit. Routine maintenance will be performed. Groundwater samples will be collected on a quarterly basis and analyzed by EPA Method 8021. In addition to the monitoring activities described above, treatment system effluent sampling will be performed in accordance with the NPDES r. permit to be issued. CEI anticipates the permit to have the limitations shown ' in Table 3. 10 9.

Actual influent concentrations are anticipated as being signifcantly lower. Utilizing EPA Method 8021,the detection limit for most compounds is 1 ug/L. Many of the compounds were detected only in a small number of wells and the anticipated influent concentrations are so low that no effluent limitation was proposed. Design flow rate: 50 gpm.
