JAY ZIMMERMAN L maff August 9, 2017 Mr. John Moss Facilities Engineering Manager Coats American 630 American Thread Road Marion, NC 28752 Subject: Draft NPDES Permit Renewal Permit NC0004243 Coats American -Sevier Plant McDowell County Class 3 Facility SIC Code 2269 Dear Mr. Moss: Enclosed with flus letter is a copy of the Draft NPDES permit renewal for your facility. Please review this draft carefully to ensure thorough understanding of the requirements and conditions it contains. There are several changes from the existing perms, including the following: • Receiving stream (North Folk Catawba River) has been reclassified from class C to class WS -IV on July 1St, 2017. In accordance with 15A NCAC 2B .0200, limitation for total PAHs (Polycyclic Aromatic Hydrocarbons) was added to the permit as required for WS - IV waters [See A. (1)]. • Special condition A. (4) was added for total PAHs monitoring requirement. If the first four samples all showed total PAHs less than detection, at detection level of 0.5 µg/L, the monitoring for total PAHs can be eliminated. If total PAHs is detected in any of these four sampling events, quarterly testing is required until expiration of this permit. • Limitations for total chromium were changed from 1.751bs/day to 1.3 lbs/day for monthly average, and from 3.5 lbs/day to 1.6 lbs/day for daily maximum based on hexavalent chromium limits in accordance with 15A NCAC 2B 0200 to assure no water quality standard is exceeded [See A. (1)]. State of North Carolina I Environmental Quality I Water Resources 1617 Mail Service Center I Raleigh, North Carolina 27699-1617 919 807 6300 Page 12 • Limitations for total residual chlorine (TRC) were changed from 17 gg/L to 28 gg/L in accordance with the NC water quality standard for protection of aquatic life and the Waste Load Allocations [See A. (1)]. • Effluent and upstream hardness quarterly monitoring has been added to the permit as required by the implementation of the new dissolved metal standards [See A. (1) and A. (2)] • histream monitoring at upstream and downstream Limekiln Creek has been added to the permit due to potential exceedance of surface water standards [See A. (2] • Effluent data for copper did not demonstrate reasonable potential to exceed applicable water quality standards/criteria, but the maximum predicted concentration was greater than 50% of the allowable concentration. Monitoring for total copper was changed to quarterly in this permit [See A. (1)]. • Monitoring for chlorides has been removed from Effluent Limitations and Monitoring Requirements [See A. (1)] based on no reasonable potential to exceed water quality standards. • Some of the wording has changed in Special Condition A. (3), Chronic Toxicity Permit Limit, please review each paragraph carefully. • One effluent data reported for silver was less than detection, at a detection level of less than 5 µg/L. In accordance with 15A NCAC 2B .0500 all test procedures must produce detection and reporting levels that are below the permit discharge requirements and all data generated must be reported to the approved detection level or lower reporting level of the procedure. Currently, DWR's laboratory identifies the Practical Quantitation Limit (PQL) for silver at < 1 gg/L. The allowable discharge concentration for your facility is 0.41 µg2. Therefore, future sampling for silver should analyze down to the lower reporting level of the procedure or PQLs as listed above. No Imuts or additional monitoring requirements for silver were added to the permit at this time. • Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The requirement to continue reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application has been added to your final NPDES permit. [See Special Condition A. (5)] • Regulatory citations have been added to the permit. Concurrent with this notification the Division is publishing a notice in a newspaper having circulation in the general McDowell County area, soliciting public comments on this draft permit. Please provide any written comments you may have to the following: NCDEQ/DWR, NPDES Permitting Branch, 1617 Mail Service Center, Raleigh, NC 27699-1617 no later than 30 days after receipt of this draft permit.

(3) CHRONIC TOXICITY PERMIT LIMIT (QUARTERLY) [15A NCAC 02B.0200] The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 15%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 2010) or subsequent versions. The tests will be performed during the months of February, May, August, and November. 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. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple -concentration testing shall be performed at a minimum, in each of the two following months as described in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -December 2010) or subsequent versions. All toxicity testing results required as part of tlus permit condition will be entered on the Effluent Discharge Monitoring Form (MR -1) for the months in. which tests were performed, using the parameter code TGP3B for the pass/fail results and THP313 for the Chronic Value. Additionally, DWR Form AT -3 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, NC 276994621 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, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. 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 a month in which toxicity monitoring is required, 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, monitoring will be required during the following month. Assessment of toxicity compliance is based on the toxicity testing quarter, which is the three month time interval that begins on the first day of the month in which toxicity testing is required by tlus permit and continues until the final day of the third month. Should any test data from this monitoring requirement 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, minimum control organism reproduction, and appropriate environmental controls, shall constitute an Page 5 of 9 Pernnt NC0004243 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. A. (4) TOTAL PAHS (POLYCYCLIC AROMATIC HYDROCARBONS) MONITORING [ 15A NCAC 02B.02001 The Permittee shall apply quarterly monitoring for total PAHs for both effluent and instream sampling, including parameters listed below: 1 -Methylnaphthalene 2 -Methylnaphthalene Benzo(a)anthracene Benzo(a)pyrene Benzo(b)fluoranthene Benzo(g,h,i)perylene Benzo(k)fluoranthene Chrysene Dibenzo(a,h)anthracene Fluoranthene Indeno(1,2,3-cd)pyrene Naphthalene Phenanthrene Pyrene For all 12 sampling events in the first year (4 effluent samples and 8 instream samples), if the total concentrations of above parameters are all less than detection, at the detection level of 0.5 gg/L as reported in 2016 Coats North America Site Assessment Report, the Permittee can discontinue monitoring for total PAHs. If any listed parameter is detected, the Permittee shall keep quarterly monitoring for both effluent and instream samples until the expiration of this permit. A. (5) ELECTRONIC REPORTING OF MONITORING REPORTS [G.S. 143-215.1(b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015.

(a)1 The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ / Division of Water Resources / Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 Page 6 of 9 Permit NC0004243 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21, 2020, the permittee must electronically report the following compliance monitoring data and reports, when applicable: Sewer Overflow/Bypass Event Reports; Pretreatment Program Annual Reports; and Clean Water Act (CWA) Section 316(b) Annual Reports The permittee may seek an electronic reporting waiver from the Division (see "How to Request a Waiver from Electronic Reporting" section below). 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity for receiving electronic NPDES data [see 40 CFR 127 2(b)]. EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting Rule is found at: https://www federalre ister.gov/documents/2015/10/22/2015-24954/national-t)ollutant-discharge-elimmation- system-npdes-electronic-reporting rule. Electronic submissions must start by the dates listed in the "Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting The permittee may seek a temporary electronic reporting waiver from the Division To obtain an electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data and reports shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective.
