JAY ZIMMEiRMAN February 11, 2016 Mr. David Hill, Engineering Technician Soil & Water Engineering, REU/NCDOT 1557 Mail Service Center Raleigh, North Carolina 27699-1557 Subject: Issuance of NPDES Permit Renewal Permit No. NCO085979 NCDOT-Rosman Maintenance Facility Transylvania County Facility Class PCNC Dear Mr. Hill: Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). No changes were made to the draft permit sent to you on September 23, 2015. The final permit authorizes the NCDOT to discharge wastewater from its Rosman Maintenance Facility to French Broad River, a class B-Trout water in the French Broad River Basin. The permit includes discharge limitations or monitoring for flow, pH, chloride, and organic compounds (EPA Methods 624/625). According to the definition of Physical Chemical Non Category (PCNC) provided by the NC D WR Operator Certification Program and the agreement from the ARO that this facility does not require an ORC, the Rosman Maintenance Facility was reclassified as PCNC. Please note that PCNC class only indicates the Division is not requiring designated operators. All other permit requirements shall remain in force. As identified previously, the renewal permit contains the following significant changes from your current permit: • The requirement to begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to your NPDES permit. [See Special Condition A.(3.)] For information on eDMR, registering for eDMR and obtaining an eDMR user account, please visit the following web page: http://aortal.ncdenr.org/web/wq/admin[bogLpu/edmr. For information on EPA's proposed NPDES Electronic Reporting Rule, please visit the following web site: hqp•//www2 epa gov/compliance/nronosed-npdes electronic reporting rule. Stale of North Carolina I Environmental Quality I Water Resources 1617 Mail service Center I Raleigh, North Carolina 27699-1617 919 707 9000 • Limitations for pH have been added in accordance with surface water quality standards in 15A NCAC 2B .0211. • Effluent sampling data for chloride did not show reasonable potential to violate NC water quality standards and the maximum predicted concentration was less than half of allowable concentration. As a result, chloride limitations were not put in the permit; however, monitoring was maintained since chloride is the primary pollutant of concern. • Some of the wording has changed in Special Condition A. (2.), Acute Toxicity monitoring, please review each paragraph carefully. The Permittee shall notice that the test results for EPA Methods 624/625 are required to include those parameters listed in the permit effluent limitation page under Footnote #4. The list is as follows: 2,4-Dinitrophenol, 2-Chloroethylvinyl ether, 3,3-Dichlorobenzidine, 4,6-Dinitro-2- methylphenol, 4-Nitrophenol, Acrolein, Acrylonitrile, Benzidine, Hexachlorocyclopentadine, Pentachlorophenol, Toluene, Bis (2-Ethylhexyl) Phthalate, Ethylbenzene, and Xylenes. 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 demand is made, this decision shall be final and binding. Please note that this permit is not transferable except after notice to the Division. 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 be required by the Division of Water Resources or any other Federal, State, or Local governmental permits that may be required. If you have questions concerning this permit, please contact Yang Song by e-mail (yang.song@ncdenr.gov) or phone at (919) 807-6479.

Part I, Page 3 of 6 Permit NCO085979 A.(2.) ACUTE TOXICITY MONITORING (QUARTERLY) [15A NCAC 02B .0500 et seq.] The Permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent Concentration" (Revised -December 2010 or subsequent versions). The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24 hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). The tests will be performed during the months of January, April, July and October. These months signify the first month of each three month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. The parameter code for Pimephales promelas is TGE6C. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Form (MR-1) for the month in which it was performed, using the appropriate parameter code. Additionally, DWR Form AT-2 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1623 Mail Service Center Raleigh, North Carolina 27699-1623 Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during any month, the Permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year' of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Water Sciences Section at the address cited above. Should the Permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin immediately. Upon submission of a valid test, this monthly test requirement will revert to quarterly in the months specified above Should any test data from either these monitoring requirements or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re -opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring. Part I, Page 4 of 6 Permit NCO085979 A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS [G. S. 143-215.1(b)] Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations will be adopted and is beginning implementation in late 2013. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit (Standard Conditions for NPDES Permits): Section B. (11.) Signatory Requirements Section D. (2.) Reporting Section D. (6.) Records Retention Section E. (5.) Monitoring Reports I. Reporting [Supersedes Section D. (2.) and Section E. (5.)

DEQ/DWR FACT SHEET FOR NPDES PERMIT DEVELOPMENT NPDES No. NC0085979/NCDOT Rosman Maintenance Facility Facility Information Applicant/Facility Name: NCDOT — Fleet and Material Management Unit (Equipment Unit) /NCDOT-Rosman Maintenance Facility Applicant Address: 4809 Beryl Road, Raleigh, NC 27606 Facility Address: 100 Old Calvert Landfill Rd, Brevard, NC 28716 Permitted Flow 0.0288 MGD Type of Waste: 100% Chloride contaminated Ground Water remediation — Road Salt storage facility Facility Class/Permit Status: PCNC/ Renewal County: Transylvania Miscellaneous Receiving Stream: French Broad River Regional Office: ARO Stream Classification: B-Trout 8-Digit HUC: 06010105 303(d) Listed? No Permit Writer: Yang Son Subbasin/ Stream Index: 04-03-01/ 6-(1) Date: February 3, 2016 Drainage Area mi2): 103 Long: 82°47'57" W Lat: 35°08'56" N Summer 7Q10 cfs 72 Winter 7Q10 (cfs): 86 Average Flow (cfs): 340 IWC (%): 0.06 Primary SIC Code: 4952 SUMMARY: NCDOT operates a 0.0288 MGD Ground Water Remediation (GWR) facility which originally was covered under General Permit # NCG510365. In 1992, a salt (chloride) pollution plume was detected in the groundwater < I mile from the former salt storage facility operated by the NCDOT. Monitoring of the plume was performed from 1992 to 1998. The highest contamination in GW was reported on 10/19/95 at a concentration of 9950 mg/L in MW-3. After performing an EAA in 1996, ARO suggested that the facility pump the contaminated groundwater and discharge it into the French Broad River. On 10/2/97 NCDOT-Rosman Maintenance Facility obtained an individual permit, NC0085979, to discharge into the French Broad River with monitoring requirements. In April 2008, the pumping system was modified by adding a fourth pumping well with lower chloride concentrations and a mixing tank to blend water from all four wells. The facility pumps groundwater from four (4) recovery wells contaminated with chlorides (road salt). The facility is required to perform continuous monitoring for flow, monthly monitoring for chloride and PH. Quarterly monitoring is required for Chemicals - EPA Method 624/625 and Acute Toxicity (Fathead Minnow) Pass/Fail. Originating in Transylvania County, the headwaters of the French Broad Rivers are in Subbasin 04-03- 01. Most of this Subbasin is forested, and half of the land is protected as part of the Pisgah National Forest. The segment of French Broad River where the Rosman Maintenance Facility discharges is not listed on North Carolina's final 2014 303(d) list. However, the 2012 North Carolina Integrated Report shows the discharge segment of French Broad River was impaired for turbidity. TOXICITY TESTING: Current Requirement: Acute P/F @ 90% (also recommended with renewal). NCDOT Rosman Maintenance Facility GWR NPDES NCO085979 Renewal Page 1 COMPLIANCE SUMMARY: The facility has passed all 20 WET tests from January 2010 through January 2015. The Rosman Maintenance Facility has a flow monthly average limit of 0.0288 MGD. From 2011 through May 2015, the average flow was 0.0062 MGD and the maximum flow was 0.012 MGD. In 2011 permit renewal, pH limits were removed with the rationale that the groundwater had naturally occurring low pH and the French Broad River offered a huge dilution factor. This facility had two instances where pH values were slightly lower than 6.0 S.U., once in 2012 and once in 2013. Since pH is a water quality standard of NCAC 2B .0200 and the facility had instances of low effluent pH, the pH limitations of "not less than 6.0 or higher than 9.0 S.U." were put in the permit. EPA 624/ 625 monitoring is not due to the chloride salts, but rather because there is an inactive county landfill adjacent to the DOT facility. Monitoring wells on the DOT site detected contamination from the landfill migrating towards the area where groundwater pumping is taking place. Vinyl chloride, benzene, tetrachloroethene, trichloroethene, and xylenes have been detected by the monitoring wells, but reportable levels have not been detected in the GWR effluent. The Permittee shall notice that the test results for EPA Methods 624/625 are required to include parameters listed in the permit effluent page under Footnote 4. The list is as follows: 2,4-Dinitrophenol, 2-Chloroethylvinyl ether, 3,3- Dichlorobenzidine, 4,6-Dinitro-2-methylphenol, 4-Nitrophenol, Acrolein, Acrylonitrile, Benzidine, Hexachlorocyclopentadine, Pentachlorophenol, Toluene, Bis (2-Ethylhexyl) Phthalate, Ethylbenzene, and Xylenes. Quarterly sampling utilizing EPA Methods 624/625 for chemical monitoring has identified two hits: 10/9/2012, Bis (2-Ethylhexyl) Phthalate, 18.6 ug/L; 7/8/2014, Ethylbenzene, 2.4 ug/L. All other samples were below reporting levels. The Division was informed by the permittee that currently only #2 recovery well pump is working and the rest three recovery well pumps are in need of repair or replacement. The permittee stated that the project to fix nonfunctioning pumps is being prepared. Reasonable Potential Analysis (RPA): The Division conducted EPA recommended analyses to determine the reasonable potential for toxicants to be discharged by this facility, based on DMR data from January 2011 through April 2015. Reasonable potential analyses were conducted for chloride, bis (2-Ethylhexyl) Phthalate, and ethylbenzene. • Chloride — effluent data showed no potential to violate water quality standards and the maximum predicted concentration was less than 50% of the allowable allocations. Considering chloride is the main parameter of concern in this permit, chloride monitoring will be maintained in NPDES permit. • Bis (2-Ethylhexyl) Phthalate — effluent data showed no potential to violate water quality standards and the maximum predicted concentration was less than 50% of the allowable allocations. Monitoring for bis (2-ethylhexyl) phthalate shall continue as part of EPA Method 624/625 monitoring. • Ethylbenzene = effluent data showed no potential to violate water quality standards and the maximum predicted concentration was less than 50% of the allowable allocations. Monitoring for ethylbenzene shall continue as part of EPA Method 624/625 monitoring. INSTREAM MONITORING: Not in current permit. Not requested for renewal permit.

His well is located approximately 350 feet north of the former salt storage bin in the Maintenance facility. The Division of Water Quality determined that his well contained chloride at concentrations exceeding twice those allowed by the NCAC 2L Standards. The source of the chloride contamination was later confirmed to be the old salt bin. A new salt storage dome was constructed near the back of the DOT facility, procedures for improved handling of salt were implemented and the old salt bin was no longer used to store salt. From 1992 until June 1998, a series of monitor wells were installed and periodically sampled to track the migration of the chloride plume. In general, the concentrations peaked in mid-1995 before beginning a slight decrease. Meanwhile the plume threatens other supply wells in the neighborhood. In 1996, the Asheville Regional Office suggested that contaminated groundwater could be discharged directly into the French Broad River without treatment. In 1996, S&ME prepared and submitted a NPDES permit application for discharging contaminated groundwater into the French Broad River. Permit #NC0085979, effective April 1, 1997, was issued for the discharge of up to 86,400 gallons per day of effluent. In 1998, Aquaterra Engineering installed the recovery system, which began operation in June 1998. The system consisted of 3 recovery wells, a shed containing a control panel and flow meters, and a 4-inch diameter discharge line that extends to the river along SR 1129. A fourth recovery well was installed in an area of the plume with lower chlorides levels in efforts to minimize chloride concentrations in the effluent in attempt to pass the acute toxicity requirements of the permit. Since the installation of this well, there have been no problems remaining in compliance with the permit. In the seventeen years the system has been in operation, it's pumped over 17 million gallons of chloride contaminated groundwater and discharged it into the French Broad River. Alternatives for Surface Water Discharge When the contamination problem was first discovered, the first option explored to meet the requirements of Groundwater Section was to extend the city water supply lines from Rosman. The City of Rosman and Transylvania County were trying to get Federal funds to extend the water line to the area just east of the DOT known as Calvert. If the supply wells within 1,500 feet of the chloride plume were replaced by city water, DOT would not have to discharge contaminated groundwater. After several years, Federal funds could not be attained and the plan for expansion of city water was cancelled. Another option was to install a pump and treatment system to remediate groundwater. Ideally, a 100% efficient system would remove all of the chloride, which would result in the discharge of clean water and the production of solid salt that would be returned to our salt storage bin. Even the most efficient systems (75 to 90% efficient) would still produce a concentrated solution that would have to be disposed of. A system like this would cost $100,000 to $200,000, but the disposal cost of the 10 to 25% concentrate makes the project unfeasible. Without having an ocean to discharge into or an industry such as a pickle factory nearby, disposal costs could run into the millions of dollars per year. There are larger treatment systems (de-salinization plants) that are 100% efficient used for municipal water supplies. However, these systems cost in the millions of dollars. Subsurface discharge was another option that is used in fuel remediation projects. However, a treatment system that produces a concentrated solution would be needed and the same problem of disposal costs must be considered. It would be difficult/expensive to have -a treatment system that would remove enough chloride to return the water to naturally occurring conditions. The next option was install a groundwater recovery system and haul all of the discharge to the nearest acceptable location. Again, the distance to the nearest disposal point makes this impractical. The Asheville Regional Office suggested the answer to the problem. The ARO asked the DOT to consider discharging water directly into the French Broad River, which is a little over 1 mile away from the DOT facility. Since there is a significant drop in elevation from the DOT facility to the river, effluent would flow by gravity to the river without the use of expensive pumping stations. A DOT contractor designed and installed the system for about $106,000. Summary of Analytical Results In accordance with the existing permit, the DOT has been sampling the effluent every month. In January, April, July and October, the sample is analyzed for chlorides, total dissolved solids, volatile organics by Method 624, semi volatile organics by Method 625, and acute toxicity. For the months in between, the sample is analyzed for chlorides only. The samples have been being collected by James & James Environmental and analyzed by Pace Analytical in Asheville and reported to the Division of Water Quality. In the past year, all acute toxicity tests have passed and there have been no organic compounds observed by methods 624 or 625 during the quarterly sampling. The highest concentration for chlorides was observed on August 28, 2014, with a concentration of 737ppm. Sludge Management The recovery system does not generate any sludge. There are no sediment traps, oil water separators or holding tanks to accumulate solids. Turbidity tests have been conducted in the pasts with levels being minimal at most (turbidity testing is no longer required per email conversations between Eric Motzno and Jim McKay on Thursday November 10, 2011). The chlorides being recovered are in solution and not exposed to any evaporative or filtering process.
