Box 26969 Greensboro, NC 27419-6969 Subject: Wasteload Allocation History Guilford Mills/East Division (NC0002305) Duplin County Dear Mr/ i er As per my recent phone conversation with John Grey, I am enclosing a summarized history of the wasteload allocations developed for the NPDES permit for the Guilford Mills/East Division. In our discussion John explained that you had expressed concerns in regard to the modeling that may have been utilized to determine the wastewater discharge limits for the referenced facility. I believe the attached chronology may shed some light on those concerns. As I explained to John, there has not been a great deal of modeling involved in the determination of limits for this facility. Rather, as best I can glean from the files, the limits were originally determined by a combination of simplistic decay analysis and federal effluent guidelines. Due to our inability to model swamp streams with conventional dissolved oxygen (DO) models and the available instream data showing low DO levels in that vicinity of the N.E. Cape Fear River, limits have been carried forth in the permit with no increase in pollutant loading (for oxygen demanding wastes) since the original promulgation. As the plant has grown in terms of production and influent volume, as well as influent pollutant loading, the resulting limits have become more stringent and difficult to meet. I hope my chronology provides some worthwhile insight into the Division's rationale as it has evolved. Please be aware that the chronology is taken straight from my file notes, so it may have arcane abbreviations and/or shorthand that are hard to follow. Please feel call me at 733- 5083, extension 507 if any translations are necessary. Please also contact me if you would still like to meet and discuss the wasteload allocation in detail after reviewing my summary. Sincerely, Jason C.

Westall) 11/77 Analysis was done for a 0.5 MGD discharge to the NECFR (class C-SW) with a DA of 310 mi2 and 7Q10=6.5 cfs. Based on a simplistic velocity and decay rate analysis, water quality limits were assigned for BOD5/NH3N of 15/12 (mg/1) with DO=5 mg/1. Other limits were also given —* pH=6-9, fecal=1000, TSS=381/763 #/d. COD=1050/2100 #/d, Cr=0.5/2.0 #/d and limits for phenols and sulfides were assigned at a non -detect std. Second WLA (C. Heavener) 2/84 WLA was updated to reflect new BPT guidelines for the textile industry. A water quality limit was assigned for BOD5 =19 mg/1. Other limits were based on BPT and given as follows: COD 4000/8000 #/day TSS I1090/2180 LW/day Sulfide 10/20 -#/day Phenols I5/10 k#/day Total Cr 4.3 otg/1 pH 16-9 .u. DO 5 BPT limits were based on guidelines from 40 CFR 410.52 and 410.53 for production of 100,000 #/day. DA is changed to 326 mi2 but stream statistics remained unchanged. Third WLA (C. Heavener) 4/84 WLA was done for an increase in waste flow to 0.965 MGD. The increase caused the water quality based limit for BOD5 to be reduced to 11 mg/1 and water quality limit for Cr to 2.26 mg/1. All other limits and stream flows were renewed unchanged. Second and third WLAs were based on Level-B models derived from Forest's 1977 WLA. Fourth WLA (M. Scoville) 3/89 Scoville's WLA was done for a straight renewal with no change in waste flow. Water quality limits for BOD5, DO and pH remained unchanged. Other limits changed as follows to reflect change in federal guidelines: COD I 4750/9500 #lday TSS 1035/2071 #/day Sulfide I 9.5/19.0 #/day Phenols 4.75/9.5 #/day The Cr limit was updated to 0.266 mg/1 (via mass balance) and notes indicate that the previous limit was not adequate to protect water quality. A chronic toxicity testing requirement was added to the permit with a P/F @ 19% limit (reflecting IWC) and monitoring for O&G, Zn and Cu was also added. Fifth WLA (D. Goodrich) 12/93 WLA was performed for an expansion from 0.965 to 1.25 MGD. WLA cover sheet indicated that production increased from 95,000 #/day to 500,000 #/day. Water quality based BOD limits were lowered to reflect no increase in loading to the system from (mon avg/daily max) of 11/16.5 to 8/12 mg/1, and effluent DO limit was raised to 6.0 mg/1 limits were recommended as follows: Recommended Limits Wasteflow (MGD) Pre -expansion Monthly Avg 0.965 Daily Max Post -expansion Monthly 1.25 Daily Tax BOD5 (mg/1) 11 16.5 8 12 COD (lbs/day) 4750 9500 3000 6000 DO (mg/1) 5.0 5.0 6.0 6.0 TSS (lbs/day) 1035 2071 1035 2071 Total Chromium (µg/1) 266 217 pH (SU) 6.0-9.0 6.0-9.0 6.0-9.0 6.0-9.0 Temperature (°C) monitor monitor monitor monitor TP (mg/1) monitor monitor monitor monitor TN (mg/1) monitor monitor monitor monitor Sulfide (lbs/day) 9.5 18.0 10 20 Chronic Toxicity P/F @ 19% (Jan, Apr, Jul, Oct) P/F @23% (Jan, Apr, Jul, Oct) Fecal (/100 ml) 200 Chlorine (g/1) 28.0* Phenols (lbs/day) 4.75 9.5 5.0 10.0 Zinc (µg/1) monitor monitor Chloride (mg/1) monitor monitor Copper (µg/1) monitor monitor Oil and Grease (mg/1) monitor monitor Temperature (°C) monitor monitor *Total residual chlorine should only be limited/monitored if added to the waste stream. It should be noted that when the permit was issued that the monthly average concentration limit for BOD5 was dropped in favor of a 83.4 #/day mass limit. Daily mass limits were still expressed in mass and conc. at 125.1 #/day and 12 mg/1. Draft SOC (M. Williams) 5/96 The Wilmington Regional Office has recently raised the concem that the river channel is extremely braided at the outfall location and that the discharge is no to the main channel, but rather to a side channel with little or no flow during drought periods. It has been recommended that toxicant and wet test limits be adjusted accordingly to account for the amount of flow available to the discharge in the immediate outfall area, or that the outfall be relocated to the main channel, if such a phenomenon exists. The regional office has drafted an SOC that with required GM to: 1) Do a flow study, develop a survey transect and "model the flow regime" in the outfall area by 6/30/97; 2) Determine a coarse of action by 7/31/97; 3) Construct necessary improvements by 9/30/98; and 4) Achieve compliance by 10/30/98. Exact details of the flow study and required "modeling" are yet to be determined. Stream Classification N.E. Cape Fear River C-SW 9/1/74 (from source to Muddy Creek) Instream Data DEM Ambient Data DEM maintains no ambient station in the vicinity of this discharge. Self Monitoring Instream Data GM's instream monitoring data from summer of 1993 shows violations of the 5.0 mg/1 DO std. However, the upstream station shows more frequent and severe excursions below 5.0 mg/1 than downstream. The differences may be attributable to the changing hydrology of the stream, from braided swamp to defined channel, but no significant tribs join the river between the upstream and downstream sites. The data from summers of 1994 and 1995 shows typical seasonal temperature fluctuations but very little fluctuation in DO levels from winter to summer. Suspiciously high DO levels (7-9 mg/1) for a swamp system are often reported. The data is suspect and should not be used to draw any substantive conclusions about the impact of the discharge. The data also always shows little or no difference between upstream and downstream conductivity levels. Current WLA - Approach/Recommendations Oxygen Demanding Wastes Due to the uncertainty of the impact of this discharge on the receiving swamp, past expansions have been permitted with no increase in loading for oxygen demanding wastes. In the last WLA, the monthly concentration limit for BOD5 was dropped so as not to discourage water conservation measures. Given the apparent unreliability of the facility's self monitoring instream data, the uncertainty during the past allocations is as present as ever. The expansion to 1.5 MGD should be permitted with limits reflecting no increase in BOD load, and the daily max concentration accordingly applied again. Instream Waste Concentration This discharge is to a small side channel at the edge of the swamp, rather than to a main channel. The Division does not currently possess the reconnaissance to determine how far across the swamp the main channel is or whether or not one even exists. In a 6/19/96 phone conversation, Mike Williams (Wilmington Regional Office) explained that he had been to the outfall during low flow conditions, and there was a barely discernable flow reaching the discharge point. Based on this assessment an IWC of 90% should be assumed until the results of Guilford's flow study/transect are available. The corresponding permit limits will most likely be superceded by SOC until study results are available. The permit should contain a re -opener clause to allow adjustment of all IWC/dilution based limits once the study is completed and an alternative is chosen by the permittee (see SOC and/or summary in my notes). WET Test Limits Past toxicity test has been the std. chronic (Ceriodaphnia) 24 hr quarterly test with a P/F limit of 19% for 0.965 MGD and 23% for 1.25 MGD. Files show 4/21/95 A to C allowing permittee to construct necessary facilities to expand to 1.25 MGD, but CMS still shows a flow limit of 0.965 MGD. Facility previously had problems with toxicity test compliance, failing majority of tests in 1992 and 1993, but has improved dramatically since, passing last 6 tests in a row and 11 of last 14. As per above assumption with IWC, WET test limit should be renewed at P/F @ 90% (SOC calls for full range monitoring). This limit will be adjusted accordingly after study results come in and course of action is chosen. Individual Toxicants Limits and monitoring for toxicants should also be assigned according to the assumed IWC=90% and then adjusted after a final dilution is reached. The existing permit has monitoring for Cu, Zn, and chloride and a water quality based limit for Cr. Facility discharges extremely high levels of Cu, as high as 405 mg/1 in the last two years. Cu monitoring should continue. If facility did not have such a good tox test record recently, these Cu levels would warrant serious concerns. Zinc levels consistently exceed allowable load of 56 mg/1, no Zn monitoring should also continence. Chromium levels also regularly exceed allowable load, so a water quality limit of 56 mg/1 should be applied. Highest reported value in the last year was 85 mg/1 on 8/9/95. Sulfide and phenol limits are stipulated in federal effluent guidelines and should be renewed accordingly. Chloride monitoring should continue because chlorides are commonly prevalent in textile waste streams. Reported levels have been as high as 85 mg/1. Instream Monitoring Renew as existing. Clarify sites see fact sheet. Federal Guideline Limits Previous guideline limits were based on production rate of 100,000 #/day, but the current production increase calls for a monthly average production rate of 112,000 #/day and a daily max rate of 120,000 #/day. The increased rates cause an increase in allowable pollutant loading as calculated by 40 CFR 410.52 (Subpart E). Due to the uncertainty of this discharge's impact on the receiving swamp system no increase should be allowed for BOD, COD, or TSS. Limits for sulfides, phenols and pH should be applied according to the guidelines. However the guideline limit for Chromium is far less stringent than the limit that would be applied according to NC Water Quality Stds. The NC Water Quality limit should be used. 4a r2a .X.re P‘.4 74.

In a letter dated August 15, 1997, DWQ concurred with the recommended alternative of relocating the outfall to the main channel of the river. Historically, the effluent limitations for the Guilford East Plant have been figured using the full flow of the Northeast Cape Fear River. After DWQ staff visited the outfall in 1994, it was determined that the outfall actually discharged into the fringe of the swamp bordering the river. As a result, the limits in the permit issued on November 1, 1996, were figured using a flow rate that was a fraction of the full river flow. Guilford Mills entered into the consent order with the state in order to have time to address this situation and to come up with a solution. The consent order contains in it an increment of progress for the submission of an NPDES permit application if it is determined that the outfall will be moved and that new limits are needed. Therefore, this NPDES permit application is being submitted in order to request that new permit limits be figured for the Guilford East Plant using the full flow of the Northeast Cape Fear River. Page 2 Mr. Goodrich Since the effluent limitations contained in the NPDES permit issued on November 1, 1994, were figured using the full flow of the river, and since after the outfall relocation, the effluent will be discharged into the full flow of the river, we request that the permit limitations in the new permit be returned to what they were in the permit issued on November 1, 1994, with the following exceptions: The flow in the new permit should be 1.5 MGD (as contained in the permit issued November 1, 1996), and the chronic toxicity testing percentage should be 27% effluent. In summary, Guilford Mills requests the following limitations in the new permit for the relocated outfall: • Flow limitation of 1.5 million gallons per day (MGD) . • Chronic Toxicity testing quarterly (pass/fail) at 27 % effluent, corresponding to the IWC of the 1.5 MGD effluent flow. • Chromium daily maximum concentration limit of 217 ug/L at the 1.5 MGD flow. • Total Residual Chlorine daily maximum limitation of 28 ug/L at the 1.5 MGD flow. The company believes this is an appropriate limitation for this parameter since this value is at the limits of detectability. In the August 15, 1997, letter referenced above, DWQ requested that Guilford Mills provide the Division with the results of any polymer testing conducted since the toxicity study report was produced and/or any results not enumerated in the report. Polymer selection trials started this week and no results are available yet. All previous results have been provided to DWQ. The Division also requested in the letter that the NPDES application package contain detailed plans of how and when the facility plans to use polymer addition or any other methods of solids removal to mitigate the adverse impacts of the effluent on the receiving stream. At this point, the facility is going through a polymer selection process. Once a polymer is selected, bench scale toxicity studies will be performed on coagulated and uncoagulated samples. This will be followed by field trials and field toxicity studies. We estimate that this process will take 60 to 90 days. It is premature at this point to provide detailed plans of how and when the facility plans to use polymer addition. This information can be provided after the trials and studies are complete. Mr. Goodrich Page 3 Finally, in regards to the potential cooperation of Guilford and Cogentrix in the outfall relocation project, Guilford Mills has submitted a proposal for this project to Cogentrix. If Cogentrix is interested in proceeding further, we will contact you to determine to permitting ramifications. A copy of the effluent limitations from the permit issued on November 1, 1994, is attached for your reference. Please call me at (910) 316-4319 with any questions or if you need any additional information. Sincerely, ( Jimmy Summers Corporate Environmental and Energy Manager cc: Brent Turner, Keith Westbrook John Grey - Grey Engineering A. ().
