The criterion currently used is based upon EPA studies using a soluble species of sulfide. Dye sulfides produced from textile processes are only slightly soluble. Therefore,review and analysis for this parameter was very conservative as the soluble sulfide criterion's were applied. Three other important factors involved in the potential toxicity of sulfide, (i.e. the formation of hydrogen sulfide) were pH, temperature, and,0 dissolved oxygen. Both effluent and instream data indicated that pH was generally in the 7.0 range, therefore only about 50% of the soluble sulfide in the effluent would be available for the 7 production of hydrogen sulfide, (taken from EPA study findings). Temperatures were normal for' this area and dissolved oxygen levels rarely dipped below 7.0 mg/1 instream, (from 1995 instream data). Hence, the possible formation of hydrogen sulfide has a very low potential. This finding, coupled with the consistent passing on the toxicity test, the low IWC, and the changes in processes in the plant which no longer use sulfidcdyes leads to a recommendation that --3 monitoring of tris parameter be droppeTirom the permit. Request Region input.,/,,.‘- Q‘'` CA) - Facility included an "Engineering Alternatives Analysis" in the application for this permit renewal. ,_ As part of this two page overview, connection to the City of Eden WWTP was discounted as an option. This was based upon the City of Eden being under a consent order, (which expired in 1992) and upon increased costs involved in meeting POTW pretreatment standards. The City of Eden already receives one discharge from a Fieldcrest.Cannon plant and does have the capacity to take on this plant with little to no pretreatment requirements. Connection to the City of Eden may require a pump station, but that is not known for sure at this time. It is requested that another, (more complete)Engineering Alternatives Analysis be performed for issuance of this permit.

Facility Name Fieldcrest Cannon, Inc Permit# NC0001643 Pipe# 001 ACUTE TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY) 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." The monitoring shall be performed as a Fathead Minnow (Pimephales promelas) 24 hour static test, using effluent collected as a 24 hour composite. The effluent concentration at which there may be at no time significant acute mortality is 90 % (defined as treatment two in the North Carolina procedure document). Effluent samples for self-monitoring purposes must be obtained during representative effluent discharge below all waste treatment. The first test will be performed after thirty days from the effective date of this permit during the months of February, May, August, and November. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGE6C. Additionally,DEM Form AT-2(original)is to be sent to the following address: Attention: Environmental Sciences Branch North Carolina Division of Environmental Management 4401 Reedy Creek Road Raleigh, N.C. 27607 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 any single quarterly monitoring indicate a failure to meet specified limits, then monthly monitoring will begin immediately until such time that a single test is passed. Upon passing,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 Environmental Management 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 retesting(within 30 days of initial monitoring event). Failure to submit suitable test results will constitute noncompliance with monitoring requirements. 7Q10 370 cfs Permitted Flow 0.500 MGD Recommended by: IWC 0.21 Basin & Sub-basin 03-02-03 Receiving Stream Dan River Farrell Keo :h County Rockingham Date zz oave.s tea QAL PIF Fathead 24 Version 9/91 Request# 8514 .

APAM requirement was also dropped. Color had been an ongoing issue in this area and numerous letters and memo's exist in file about it. Toxicity Test passing since 1992 Instream Date no violations-generally above 7.0 mg/I(attached) Sulfide Attached is a fax from EPA regarding sulfide toxicity. A number of issues need to be addressed regarding this study: • First,the paper focuses on the most toxic of the compounds which could form from sulfides in the effluent;hydrogen sulfide. Unfortunately,to achieve this compound formation,the sulfide needs to be soluble. Both the Hawley's Condensed Chemical Dictionary, 12th ed., Richard J. Lewis,Sr.and Chemistry,2nd ed.,Steven S.Zumdahl note that sulfide dyes are only slightly soluble, (or not soluble). • The second aspect is that pH is a strong influence as to the amount of effluent sulfide which can combine to form hydrogen sulfide. In other words,at a pH of 7.0,(which is the general range of pH for both the effluent and instream)approximately 50%of the effluent concentration can form into hydrogen sulfide. • It was also stated that in well-aerated water, H2S is oxidized back into sulfates and hydrogen, (which often discounts its possible toxicity). • These factors are addressed further in the latter sections of this paper,but generally the lowest numbers for toxicity are determined via laboratory procedures using juveniles and eggs and fry for species not existing in this waterbody. • Finally, no standard exits for sulfides for either the State or Federal government. • Also, it should be noted that fish are sensitive to hydrogen sulfide and will leave the area given an escape route,(which should easily exist considering this discharge has a 0.25% IWC). Finally,this facility has a consistent record of passing its toxicity and the processes requiring sulfide dyes are not used,(and haven't been used here since the last WLA in 1993). To view the data for this parameter I chose to use the 0.3-0.4 mg/I concentration and doubled*it since only about 50%of the effluent sulfide would be soluble for the 7.0 pH at this facility-note that I assumed that this effluent sulfide was soluble to keep a conservative focus upon this parameter. Using this number,the allowable effluent concentration would be 334.9 mg/I and the maximum predicted concentration, (using only 5 samples available for analysis)would be 32.3 mg/I which is not within one-tenth of the allowable. Therefore,considering the conservative nature of this allowable level, it seems justifiable to drop the monitoring requirement. since 2 for the price of one is the same as 50%off, I doubled the allowable rather than cut the effluent data in half,(which had the potential of throwing the statistics off).

INTRODUCTION: Hydrogen sulfide is a soluble, highly poisonous, gaseous compound having the characteristic odor of rotten eggs. It is detectable in air by humans at a dilution of 0.002 ppm. It will dissolve in water at 4 , 000 ng/L at 20° C and one atmosphere of pressure. Hydrogen sulfide biologically is an active compound that is found primarily as an anaerobic degradation product of both organic sulfur compounds and inorganic sulfates. Sulfides are constituents of many industrial wastes such as those from tanneries, paper mills, chemical plants, and gas works. The anaerobic decomposition of sewage, sludge beds, algae, and other naturally deposited organic material is a major source of Ha.ilcv-s cdN1io.N,5.04 ci.�Mtcnll�,cTroNIDRK' IZ `wel-, R•clAado,jv Tot Su1Fldc dC3 ARE a¢C. oNltz hydrogen sulfide.

In winter when the pH is neutral or below or when dissolved oxygen levels are low but not lethal to fish, the hazard from sulfides is exacerbated. Fish exhibit a strong avoidance reaction to sulfide. Based on data from experiments with the stickleback, Jones (1964) hypothesized that if fish encounter a lethal concentration of sulfide there is a reasonable chance they will be repelled by it before they are harmed. This, of course, assumes that an escape route is open. Many past data on the toxicity of hydrogen sulfide to fish and other aquatic life have been based on extremely short exposure periods. Consequently, these early data have indicated that concentrations between 0.3 and 0.4 mg/L permit fish to survive (Van Horn 1958, Boon and Follis 1967, Theede et al. , 1969) . Recent : ong-term data, both in field situations and under controlled laboratory conditions, demonstrate hydrogen sulfide toxicity at lower concentrations. Colby and Smith' (1967) found that concentrations as high as '. 0.7 mg/L have been found within 20 mm of the bottom of sludge beds, and the levels of 0.1 to 0.02 mg/L were common within the • • 04/19/93 14:24 WATER t14Jr-C,EIEtJT REGION IV - 919 733 9919 NO.572 D04 first 20 nm of water above this layer. walleye (Stizoet,,,edion _ • vitreur..) eggs held in trays in this zone did not hatch. Adelman • and Smith (1970) reported that the hatchability of northern pike (Esox lucius) eggs was substantially reduced at 25 ug/L H2S; at 47 ug/L mortality was almost complete. Northern pike fry had 96 hour LC50 values that varied from 17 to 32 ug/L at normal oxygen levels of 6.0 mg/L. The highest concentration of hydrogen sulfide that had no observable effect on eggs and fry was 14 and 4 ug/L, respectively. Smith and Oseid (1972) , working on eggs, fry and juveniles of walleyes and white suckers (Catostomus commersoni) and Smith (1971) , Safe levels in working on walleyes and fathead minnows, Pimephales promelas, were found to vary from 2.9 ug/L to 12 ug/L with eggs 'being the least sensitive and juveniles being the most sensitive in short-term tests. In 96- hour bioassays, fathead minnows and goldfish, Carassius auratua, varied greatly in tolerance to hydrogen sulfide with changes in temperature. They were more tolerant at low temperatures (6 to loo C) . Holland, et al. (1960) reported that 1.0 mg/L sulfide caused 100 percent mortality in 72 hours with Pacific salmon. On the basis of chronic tests evaluating growth and survival, ta the safe H2S level for bluegill (Lepomis macrochirus) juveniles and adults was 2 ug/L. Egg deposition in bluegills was reduced after 46 days in 1.4 ug/L H2S (Smith and Oseid, 1974) . White • • sucker eggs were hatched at 15 ug/L, but juveniles showed growth reductions at 1 ug/L. Safe level for fathead minnows were between 2 and 3 ug/L. Studies showed that safe levels for Gammarus Pseudolimnaeus and Hexagenia limbata were 2 and 15 ug/L, respectively (Oseid and Smith, 1974a, 1974b) .

Sulfide criteria for domestic or livestock use have not been established because the unpleasant odor and taste would preclude such use at hazardous concentrations. It is recognized that the hazard from hydrogen sulfide to aquatic life is often localized and transient. Available data indicate that water containing concentrations of 2.0 ug/L undissociated H2S would not be hazardous to most fish and other aquatic wildlife, but concentrations in excess of 2.0 ug/L would constitute a long-term hazard.

DRAWN BY APPROVED BY DATE I REVISION BY DATE BRIEF I ‘/g fe Southern Photo Print& Supply Co., Greensboro, N.C.*IOOOH ENGINEERING ALTERNATIVES ANALYSIS NEW STREET WWTP In considering non-discharge alternatives persuant to 15A NCAC 2H.0105 (C) (2) , the following rational is provided. Two other options could be considered for treatment of this wastewater, one is land application of the treated effluent and second would be sewer connections to the local POTW. This wastewater treatment facility was designed to treat process wastewater from two manufacturing facilities with the plans to build additional manufacturing in the future. The WWTP was designed for .5 MGD. Treatment units consist of an extended aeration activated sludge basin followed by clarification and chlorination. The detention time of the system is several days which minimizes sludge production, and provides a high quality effluent for discharge to the Dan River. Option 1 - Land Application of Treated Effluent With a design flow of .5 MGD we would need to reserve a minimum of 125 acres of land for an application of 20, 000 gallons/week/acre. This does not account for precipitation and frozen ground conditions which would require more land in reserve and additional storage. The required amount of land is not available, and significant costs for solids storage facilities, and engineering would be needed; therefore, this option is not economically justifiable. Option 2 - POTW Sewer Connections These Fieldcrest Cannon, Inc. manufacturing facilities are located outside the city limits of Eden. For the past several years the City has operated the POTW under a consent order. This has not allowed any increase in industrial wastewater contribution to the POTW. If available, significant costs to connect to the. sewer would be encountered, along with monthly sewer surcharge• costs. Many POTW's are becomimg more restrictive as to concentrations allowed in pretreatment permits, so the idea of direct discharge from the manufacturing facility to the POTW would not be allowed and pretreatment would be needed to meet the limits, adding still additional costs to the wastewater discharge. In sumary, it is our company policy to maintain and operate our own wastewater treatment facilities, when the option is available. Our records indicate that we can do this more economically and control the costs more effectively. By keeping different waste streams segregated a better treatment efficiency T • - 2 - can be obtained. This facility was designed under Textile BACT guidelines and remains capable of meeting and usually exceeding the discharge limits allowed under Federal Guidelines for the textile manufacturing industry. The discharge of this wastewater into the Dan River would have no significant impact on the water quality of the stream because Dan River has a 7Q10 of 314 cfs and with a discharge of .5 MGD and low pollutant concentration. This information should be sufficent to justify the continued existing treatment alternatives and discharge. SLUDGE PLAN NEW STREET WWTP This facility was designed with a sludge lagoon for temporary storage of biosolids wasted from the system. The capacity of the lagoon is 100, 000 gallons. At present it is only at sixty percent capacity. The WWTP currently has a low organic loading compared to design capacity. The system requires a minimal amount of solids wasting to operate efficiently. At present only several thousand gallons of dilute concentration are wasted each week to the lagoon. The water evaporates and leaves a minimal amount of residual biosolids actually stored in the lagoon. Additional storage capacity is curently available for continued operation of this lagoon for many years. _lam cc: Permits and Engineering • Technical Support Branch County Health Dept.
