REGAN Secretary Water Resources LINDA CULPEPPER Environmental Quality Interim Director March 20, 2018 Ms. Brigette Tinsley Electric Glass Fiber America, LLC 473 New Jersey Church Road Lexington,North Carolina 27292 Subject: Error Correction Letter Permit NC0004626 Lexington Plant Davidson County Class 3 Facility SIC Code 3229 Dear Ms. Tinsley: On November 30, 2017, the Division of Water Resources issued Permit Renewal (NPDES Permit No. NC0004626) for Electric Glass Fiber America's Lexington Plant. It has been brought to our attention that the Renewal needed clarification as follows: • The bi-monthly monitoring frequency for Total Residual Chlorine has been changed to twice per month in Section A. (1) Effluent Limitations and Monitoring Requirements. • The semi-annually monitoring frequency for Oil and Grease has been changed to twice per year in Section A. (1) Effluent Limitations and Monitoring Requirements. Therefore, the Division has made a correction to the appropriate pages in the Permit Renewal. Please insert the enclosed corrected sheets and discard the old sheets. This permit modification becomes effective on May 1, 2018. All other terms and conditions in the original permit remain unchanged and in full effect. These modifications are 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 December 6, 1983. If any parts,measurement frequencies or sampling requirements contained in this 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 in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed with the 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 Office of Administrative Hearings, Post Office Drawer 11666, Raleigh, North Carolina 27604.

(1) EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS [15A NCAC 02B.0400 et seq., 15A NCAC 02B.0500 et seq.] During the penod beginning on the effective date of the permit and lasting until expiration,the Permittee is authorized to discharge treated wastewater from Outfall 001. Such discharges shall be limited and monitored' by the Permittee as specified below: Effluent Characteristics Discharge Limitations Monitoring Requirements Parameter Code Monthly Daily Measurement Sample Sample Location Average Maximum Frequency Type Flow 50050 0.6 MGD Continuous Recordmg Influent or Effluent BOD,5-day,20°C 80082 157 lbs/day 314 lbs/day Quarterly Composite Effluent (April 1 —October 31) BOD,5-day,20°C 80082 314 lbs/day 630 lbs/day Quarterly Composite Effluent (November 1—March 31) Total Suspended Solids C0530 105 lbs/day 168 lbs/day Quarterly Composite Effluent (April 1—October 31) Total Suspended Solids C0530 146 lbs/day 292 lbs/day Quarterly Composite Effluent (November 1—March 31) Fecal Coliform 31616 200/100m1 400/100m1 Quarterly Grab Effluent (geometric mean) NH3 as N(mg/L) C0610 Weekly Composite Effluent pH 00400 Between 6.0 and 9.0 s.u.

The permittee shall submit discharge monitoring reports electronically using the NC DWR's eDMR application system[see A. (4)]. Page 3 of 9 Permit NC0004626 2. Total residual chlorine shall be monitored only if chlorine is added to the treatment process. The Division shall consider all effluent TRC values reported below 50 µg/L to be m compliance with the permit. However, the permittee shall continue to record and submit all values reported by a North Carolina certified laboratory. 3. The limit becomes effective June 15, 2021. This compliance schedule is provided to allow the facility to budget, design, and build the treatment system to comply with the new water quality-based limit [See A. (3)] 4. The permittee shall sample mstream hardness upstream of the facility's discharge. The sample shall be representative of the hardness in the receiving stream. If the permittee is a member of a monitoring coalition program, samplmg for instream hardness may be waived as long as the monitoring coalition agrees to sample hardness at the nearest upstream location, at a minimum frequency of quarterly, and the permittee has obtained approval from DWR-NPDES Permitting Unit that the upstream station being monitored by the Coalition is representative of the receiving stream for this discharge. The permittee is responsible for submitting instream hardness test results with its permit renewal application package. If Coalition membership is cancelled or the Coalition terminates mstream hardness sampling at the approved station, the permittee will immediately notify the Division and resume sampling for instream hardness upstream of its discharge. 5. Chronic Toxicity (Ceriodaphnia) limit at 48% with testing in February, May, August, and November [see A. (2)]. There shall be no discharge of floating solids or visible foam in other than trace amounts. A. (2) CHRONIC TOXICITY PASS/FAIL 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 48%. The permit holder shall perform at a mmimum, 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 H Chronic Whole Effluent Toxicity Test Procedure"(Revised-December 2010)or subsequent versions. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form(MR-1) for the months m which tests were performed,using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Value. Additionally,DWR Form AT-3 (origmal) 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 27699-1621 Page 4 of 9
