Permit No. NC0006196 SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS SPECIAL CONDITIONS A (2). CHRONIC TOXICITY PERMIT LIMIT (QRTRLY) • The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 12%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -February 1998) or subsequent versions using the following effluent concentrations: 48%, 24%, 12%, 6%, and 3%. The tests will be performed during the months of March, June, September, and December. Effluent sampling for this testing 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 -February 1998) or subsequent versions. The chronic value for multiple concentration tests will be determined using the geometric mean of the highest concentration having no detectable impairment of reproduction or survival and the lowest concentration that does have a detectable impairment of reproduction or survival. The definition of "detectable impairment," collection methods, exposure regimes, and further statistical methods are specified in the "North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised - February 1998) 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 in which tests were performed. If reporting pass/fail results using the parameter code TGP3B, DWQ Form AT-1 (original) is sent to the below address. If reporting Chronic Value results using the parameter code THP3B, DWQ Form AT-3 (original) is to be sent to the following address: Attention: NC DENR / DWQ / Environmental Sciences Section 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental 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 Environmental 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. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Quality indicate potential impacts to the receiving stream, this permit may be re- opened and modified to include alternate monitoring requirements or limits. If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms submitted. Permit No. NC0006190 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 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 (3). TOXICITY IDENTIFICATION EVALUATION (TIE) Should any whole effluent toxicity test produce a chronic value less than 12%, the permittee will undertake toxicity identification evaluations (TIEs) using the procedures described in Toxicity Identzjlcation Evaluation: Characterization of Chronically Toxic Effluents, Phase I, EPA/600/6-91/005F, May 1992 or similar methods. A final report will be generated and submitted to the address below no later than 60 days following the initial test producing a chronic value less than 12%. The primary objective of the TIE activity will be to confirm or rule out polymer as the source of toxicity. The report detailing findings of the TIE is to be sent to the following address: Attention: Environmental Sciences Section North Carolina Division of Water Quality 1621 Mail Service Center Raleigh, North Carolina 27699-1621 A (4). COLOR PERMITTING REQUIREMENTS Color Monitoring. The permittee will conduct color monitoring of instream stations (upstream, downstream) on a weekly basis during each summer season (April -October). The permittee will record whether a color plume was observed around the outfall pipe during the weekly instream sampling events, and include that information on the monthly discharge monitoring report. Influent and effluent samples will be collected weekly for color on a year-round basis. Color samples will be analyzed for ADMI color at natural pH. Effluent/influent samples will consist of 24-hour composites, while instream samples will be collected as grab samples. Samples will be analyzed by a state certified laboratory. The influent monitoring station will need to be located prior to polymer addition. Color Reopener. If data show that water quality standards for color are being violated by the discharge permitted by the terms of this permit, then the Director may reopen this permit for the purpose of imposing additional requirements pursuant to 15A NCAC 2H.0114. Alternatively, if future conditions change and color is no longer a component of the influent wastestream, then the permittee may request a permit modification to remove color permit requirements.

A major permit modification was issued to Delta Apparel in June 2009 as a result of the permittee's request to expand the flow from 1.0 MGD to 1.1 MGD based on . an actual production rate of 82,250 lbs/day. Since the permit modification, the discharge flow has ranged from 0.004 MGD to 1.3 MGD with an average flow of 0.87 MGD. The production rate has varied between 25,312,200 Ibs/cloth/yr to 32,877,000 lbs/cloth/yr with an average of 82,005 lbs/cloth/day. Operations generally function 7 days a week, 24 hours a day. The facility discharges 100% process wastewater, while all domestic wastewater is treated at the Town of Maiden WWTP. Sludge is land applied under permit WQ0006984. This facility was originally permitted in the 1970's and operated as Duckhead Apparel. A 1992 ATC authorized relocation of its discharge point from Shady Branch to Clark Creek. Based on planned production increases the permit was modified in January 1998 to allow expansion from 1.0 to 1.5 MGD after receiving an ATC. The permit was modified in 2000 to change the name from Delta Mills Inc to Delta Apparel Inc. A permit renewal was issued in 2002 and the Effluent Limitations and Monitoring Page for 1.5 MGD was removed maintaining the permitted flow at 1.0 MGD since the facility was able to expand production without the need for additional flow due to water conservation and reuse. The 2002 permit was contested by Delta Apparel primarily due to concerns associated with the effluent color limitations. After reaching a settlement agreement with DWQ on 8/27/2004, Delta Apparel implemented a color reducing technology and achieved significant color reductions during 2004-2005. A second color reducing technology was stipulated in the 2005 permit modification and permitted flow was maintained at 1.0 MGD. The permit was last renewed in 2006 and than modified in 2009 to allow for an increased discharge from 1.0 MGD to1.1 MGD. NPDES PERMIT FACT SHEET Delta Apparel, Inc. Page 2 NPDES No. NC0006 190 The wastewater treatment plant at Delta consists of two 1.25 million gallon aeration basins which currently receive approximately 0.5 MGD each having 60 hours retention. Polymer for color removal is added to the flow leaving the basins which enters into dual clarifiers to settle solids. A flocculation agent is added to the center -well of each 80,000 gallon clarifier. After clarification the wastestream flows through a chlorine contact tank which is no longer in use and then into an 84,000 gallon post aeration basin. Solids that settle and thicken are wasted to a sludge storage lagoon which has a capacity of 1.8 MGD. Treated wastewaters from the clarifiers discharge to a parshall flume with an ISCO flow recorder and a refrigerated composite sampler. The effluent is discharged through a 7,500-foot gravity line to Clark Creek, approximately 100-ft above the Town of Maiden's discharge point, and several miles below the Town of Newton's discharge. Clark Creek flows into South Fork Catawba River, then into Lake Wylie. Most of Clark Creek is considered impaired. The subject stream segment is Class C, and listed in the 2012 303(d) list as biologically impaired. Causes of the impairement are listed as unknown.

The instream self -monitoring includes: temperature, conductivity, dissolved oxygen, total copper and color. An analysis of instream samples for DO, temperature and conductivity for the past three summers (2010- 2012) showed one downstream DO sample at 3.8 mg/L in Aug. 2012 and one at 4 mg/L in July 2012. These two samples were below the daily average DO water quality standard of 5 mg/L. All other instream DO samples were greater than 5 mg/L. It can not be concluded that Delta is the cause of these instream violations since the Town of Maiden and Newton discharge to Clark Creek as well. See upstream and downstream data in Table 2 attached. The Level B model analysis conducted in 1997 predicted an increase to 300 lbs/day BOD5 would not impact the DO downstream of the outfall. For the years 2009 through 2012, Delta Apparel's effluent levels for BOD5 have been well below the permit limit of 162 lbs/day (monthly avg.) with a calculated mean of 17.5 lbs/day and a three year maximum value of 121.5 lbs/day — well below the WLA. The Page 2 Version: March 18, 2013 NPDES PERMIT FACT SHEET Delta Apparel, Inc. Page 3 NPDES No. NC0006 190 mean concentration for NH3-N was 0.14 mg/L which is also well below the facility's permit limit of 3 mg/L. Effluent D.O. has averaged at 7.3 mg/L. Discharge Monitoring Reports have been reviewed for the period January 2007 through October 2012. During the review period, Notices of Violation have been issued based on the following date and parameter violations: June 2012 — WET test, August 2009 — COD, April 2009 — COD, November 2008 — Flow, October 2008 — Flow, September 2008 — Flow, August 2008 — Flow, April 2008 — Flow, May 2008- Flow. Note that the facility requested and received a permit modification for a flow expansion, effective July 1, 2009. The Mooresville Regional staff performed a routine compliance inspection of the Delta Mills — Maiden Plant on 1/26/10. The staff report gave a Facility Evaluation Rating of very reliable and listed the compliance status as compliant. As a follow-up to a citizen's complant about color in Clark's Creek, Regional staff split an effluent color sample with Delta Mills on 1/12/2011 and 9/14/2011. It was discovered that the laboratory was not calculating the color units correctly. Attached is Table 3 with the monthly average Effluent Color Data showing the recalculations that the facility was requested to go back and correct between 4/7/11 and 3/15/12. The corrections showed that the facility violated its color permit limit on 8 occassions in 2011, with no violations in 2012. REASONABLE POTENTIAL ANALYSIS Reasonable potential analyses were conducted for Chromium, Copper, Zinc, Chloride and Total Phenolic Compounds (see RPA attached). Based on reasonable potential analysis of chromium data, there is no reasonable potential to exceed the in -stream chromium water quality standard. However, since the WQ- based limit is more stringent than the corresponding effluent guideline limit, the WQ-based chromium limit of 402 ug/L will be maintained in the permit. Copper, Zinc and Chloride, all exhibit some reasonable potential to violate Action Level standards. Since Action Level standards are reviewed in conjunction with toxicity testing, it is recommended that monitoring be continued for all three parameters as part of its NPDES permit at a quarterly frequency. Should the presence of these pollutants in the effluent be identified as causative factors of whole effluent toxicity, limitations will be determined. Federal Effluent Guideline Limits (EGLs). The facility is a textile knit fabric dye and bleaching operation which is subject to 40 CFR 410 Subpart E - Knit Fabric Finishing Subcategory, as a simple manufacturing operation. Although 40 CFR 410 allows for increases in EGLs based on the actual production, the Division has elected to freeze the EGL limits for BOD, TSS, Sulfide, and Phenols due to the impaired stream status and the ability of the permittee to already meet these more stringent limits. These numbers are based on 1995-1997 production rates. See Tables 4 & 5 on Textile Effluent Limits and Production Values. There are no Federal EGLs for color. The current COD daily maximum limitation was based on actual production rate in 2005 of 104,510 lbs/day. On Dec. 2012 Charles Blackwell, the Environmental Consultant for Delta Apparel submitted production hours and rates for the years 2007 through 2011 as follows: 2007 = 8448 hours Production = 32,877,000 Ibs = 93,400 Ibs/day 2008 = 8484 hours Production = 30,185,750 Ibs = 85,391 Ibs/day 2009 = 7884 hours Production = 25,312,200 Ibs = 77,054 Ibs/day 2010 = 8736 hours Production = 27,559,453 Ibs = 75,713 Ibs/day 2011 = 8616 hours Production = 28,169,677 Ibs = 78,467 Ibs/day Avg. 82,005 Ibs/day Page 3 Version: March 18, 2013 NPDES PERMIT FACT SHEET Delta Apparel, Inc. Page 4 NPDES No. NC0006190 The production level of any one year is not more than 20% above the average production level, therefore, the technology based EGL's were calculated using the highest production level of 93,400 lbs/day. All the technology based EGLs determined were less stringent than the existing limits except for those determined for COD. The new COD limitations of 5,604 lbs/day (daily max) and 2802 lbs/day (monthly average) will be put in the permit renewal. These numbers are based on a daily max and monthly avg. production number of 93,400 lbs/cloth/day established during the year of 2007. The production based limitations for Total chromium were determined to be less stringent than the state water quality standard.The existing water quality standard limitation was retained in the draft permit. Water Quality -Based Effluent Limits. The receiving stream segment is subject to water quality standards applicable to Class C freshwater streams. Previous permits included water -quality based effluent limits for ammonia, dissolved oxygen, and chromium. The WQ-based limits for chromium, ammonia and dissolved oxygen have been retained in the draft renewal. COLOR The monthly average permit color limit of 549 ADMI units is recommended to remain in the permit renewal. TOXICITY TESTING The permittee has passed 20 out of 21 WET tests with chronic values > 15.6% and one failure < 6%. Current Requirement: Quarterly Chronic Toxicity @ 12.0% MAR, JUN, SEP, DEC It is recommended that the current WET testing requirement be maintained. PROPOSED CHANGES • Change the COD effluent limitations to coincide with actual production -based levels. The daily maximum will be reduced to 5604 lbs/day and the monthly average to 2802 lbs/day. • Monitoring frequencies for copper and zinc were reduced to quarterly based on the NPDES Monitoring Frequency memo dated July 2010. • The instream sampling for copper was reduced to quarterly. Effluent Limitations and Monitoring Requirements for all the other parameters remain the same. Proposed Schedule for Permit Issuance Draft Permit to Public Notice: 01/16/13 (est.)

NC DWQ Lab: ADMI Color pH 8.6 = 290 c.u. ADMI Color pH 7.6 = 280 c.u. R & A Lab: ADMI Color pH 8.56 = 313 c.u. ADMI Color pH 7.6 = 313 c.u. These results will be included in the inspection report for R & A. Since these results are within what I would consider acceptable variance (there is no precision or bias data provided in the method) and both laboratories just recently obtained acceptable results on blind performance testing samples, I feel this issue is closed. I'd like to thank everyone involved in this investigation for their help and cooperation in figuring this one out. Donna for bringing it to our attention and collecting samples, Sid and his staff for all their cooperation and Cindy and her staff for their assistance. And especially to Jason for taking the lead on resolving this.

And the second is whether you want True color (filtered) or apparent color (unfiltered). The methods describe both. When Donna initially emailed you we were dealing with some other issues in the method — like the fact the method allows for very different pore sizes when you filter the sample — We thought that might have been a big enough variable as to explain the difference in the split samples- as it turned out that was not a factor. thanks Gary Have you signed up to receive automatic email notices of changes to policies, regulations and resources pertaining to Wastewater/Groundwater Laboratory Certification that could have an impact on your day to day operations?

Julie From: Hood, Donna Sent: Thursday, January 05, 2012 8:50 AM 1 To: Grzyb, Julie Cc: Francies, Gary Subject: Delta Apparel/NC0006190 update Hi Julie, The our second sampling at Delta showed a much higher number than the facility has been reporting/receiving from their lab. Our sample was 390 ADMI units and theirs was 188 ADMI units, and this sample was a true split. I have asked Gary Francies, whom is copied on this email, to investigate the reason for the difference in the laboratory results from our state lab versus the lab Delta is using. There may be a difference in the way the sample is processed and we may want to include some more specific language in the permit as to which lab method should be used to analyze the sample. I informed Gary that the permit is currently in the renewal phase and now would be the time to handle this clarification. He will provide us with guidance as soon as he has it. I just wanted to update you. Please let me know if you have any questions or need any more specific details.

CATAWBA COUNTY MAIDEN, NC NPDES PERMIT NO. NC0006190 PRESENT WWTP OPERATING STATUS DELTA APPAREL, INC. Wastewater from the dye and bleaching process goes to the heat reclaimer equipment for heat recovery from the hot (120°F) wastewater. Lint is filtered at this point before being discharged to the WWTP. Wastewater enters the WWTP through a bar screen, then goes into dual aeration basins. Each aeration basin is 180 feet long by 90 feet wide by 12 feet deep, and contains 1,250,000 gallons with 54.55 hours retention at 1.1 MGD of total plant flow. Polymer for color removal is added to the flow leaving the aeration basins. From aeration, the flow goes into dual clarifiers to settle solids, where a flocculation agent is added to the center -well of each clarifier. Each clarifier is 38 feet in diameter and 10 feet deep with a capacity of 80,000 gallons. From the clarifiers the flow goes through the old chlorine contact chamber and a float and cable flow recorder. From here, the flow goes into the post aeration basin that is 50 feet long and 25 feet wide and 9 feet deep with a capacity of 84,000 gallons. The flow then goes to the parshall flume with an ISCOe flow recorder and refrigerated composite sampler. From here, the flow travels 7,500 feet through a 14-inch gravity line (Outfall No. 001) discharging to Clark Creek. DELTA APPAREL, INC. CATAWBA COUNTY MAIDEN, NC NPDES PERMIT NO. NC0006190 • SLUDGE MANAGEMENT PLAN NARRATIVE DELTA APPAREL, INC. Solids that settle and thicken in the clarifiers are wasted at a rate of 50,000 gallons-100,000 gallons per week. The waste rate can vary with the mixed liquor total solids, flow, and sludge depth in the clarifiers. Sludge is wasted into the sludge storage lagoon, which has a capacity of approximately 1,800,000 gallons. During wasting and storage, the sludge is aerated with seven (7) surface aerators. Decant is pumped back into the aeration basins. When the lagoon nears capacity, a professional contractor hauls the solids to various sections on 240 acres of pasture for land application. Land application of these biosolids is carried out within the regulations of Permit No. WQ0006984. DELTA APPAREL, INC. CATAWBA COUNTY MAIDEN, NC NPDES PERMIT NO.
