Facility Name Stanley WWTP Permit # NC0020036_ Pipe # 001 _ CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QRTRLY) The effluent discharge shall at no time exhibit chronic toxicity using test procedures outlined in: 1.) The North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Procedure - Revised *September 1989) or subsequent versions. The effluent concentration at which there may be no observable inhibition of reproduction or significant mortality is 79 % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform Quarterly monitoring using this procedure to establish compliance with the permit condition. The first test will be performed after thirty days from the effective date of this permit during the months of JAN APR JUL OCT .. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. 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 TGP3B. Additionally, DEM Form AT-1 (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 this monitoring requirement 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 0.41 cfs Permitted Flow 1.0 MOD IWC 79 Basin & Sub -basin CTB35 R-„�•mmended by: Receiving Stream Mauney Creek f / County Gaston ' ate 3/16/95 QCL PIF Version 9/91 Facility Name: NPDES No.: Type of Waste: Facility Status: Permit Status: Receiving Stream: Stream Classification: Subbasin: County: Regional Office: Requestor: Date of Request: Topo Quad: FACT SHEET FOR WASTELOAD ALLOCATION Request # 8038 Stanley WWTP NC0020036 76% Domestic / 24% Industrial Existing Renewal ( Ul l Tl-i- Mauney Creek WS-IV 030835 Gaston MRO �f2AC. Lucas 10/25/94 F14SE Wasteload Allocation Summary (approach taken, correspondence with region, EPA, etc.) Facility requesting renewal of existing NPDES permit with modification for expansion to 1.4 MGD. MRO staff have concerns with expansion to 1.4 MGDAaja have recommended that lesser wasteflows of 0.8, 0.9, and 1.0 MGD be given consideration. Instream data shows DO levels below 5 mg/1 downstream of Stanley's discharge. MRO recommends that Town provide design calculations for the clarifiers and chlorine contact tank before modification of the permit is granted. When these stipulations are met, limits will be recommended w/ continuation of whole effluent tox test and quarterly monitoring for metals. This* limi'°s iic&mmended because of toxicity record of facility and pretreatment's short term monitoring plan which will not provide enough data to • evaluate the facility at next permit renewal. cxpan6r(,0144- f0 inC/t ix fat cl' to ) vJ Q�' tL t,cpcut6ions abet 1.0010 -zi);/! , ne ru411 int s+a-e Special Schedule Requirements anadditional comments from Reviewers: �� T4 4Yf4f 4L G'CGN I / /k /1Hcrti . / .1//Ci "k49' 7 /5 R/ cSf grucf7Y-U'i// hr -75 S'tid emu. �(eii l 1( r/- mod. /l 'ewe. fv (7e e%ri . - 141.4 r( ma's 5:6404444 pay/ aft c a /id'r/i� y ,C ,.tfrtfi k)i ?v ! .

Page 1 Note for Carla Sanderson From: Jackie Nowell Date: Tue, Apr 25, 1995 12:01 PM Subject: STANLEY WWTP To: Dave Goodrich Cc: Carla Sanderson; Jay Lucas Per your comments on the Stanley Factsheet, 4/23/95. The expansion request to 1.4 MGD has not been ignored. A meeting w/ the Town of Stanley was held on 3/27/95, attended by Construction Grants, Kim Colson of MRO, Jay Lucas of P&E, Carla and myself. At that time, we discussed the expansion to 1.4 MGD and Kim Colson reiterated the RO position that the existing system would not be able to accept that amount of flow. The Town and their consultants had been notified of these concerns before and knew that the Region felt that, at best, only 1.0 MGD of flow could handled by the old clarifiers. In the meantime, a EA has been done, and CG is trying to finalize the funding. The funding would not include building clarifiers that would accept 1.4 MGD of wasteflow. At the meeting, after much discussion, it was decided that the Town would revise their request from 1.4 MGD to 1.0 MGD. A letter requesting the revision was sent to Jay on 4/5/95 and MRO sent a letter to Cecil Madden on 4/4195 recommending that plans and specs for the Stanley WWTP be approved for a flow of 1.0 MGD. Regarding the instream DO's < 5 mg/1, there were 2 months reported in 1994. These values were reported after Tech Support had reviewed the EA and we had no objections to the expansion request in our comments. The process had already started and with the Town also over 90% capacity, we did not feel we could deny any expansion at all. Because of that, we decided to allow expansion with no increase in loading. I hope this sheds some light on the Stanley situation. Please contact me if you have additional questions.

North Carolina Ceriodaphnia chronic effluent bioassay procedure (North Carolina Chronic Bioassay Proceure - Revised *September 1989) or subsequent versions. The e uent concentration at which there may be no observable inhibition of reproduction or significant mortality is _7 _% (defined as treatment two in the North Carolina procedure document). The permit holder shall perfo quarterly monitoring using this procedure to establish compliance with the permit condition. The first test be performed after thirty days from the effective date of this permit during the months of _JA APR JUL. OCT .. Effluent sampling for this testing shall be performed at the NPDES permitted final efflue t discharge below all treatment processes. All to 'city testing results required as part of this permit condition will be entered on the Effluent Discharge Monit ring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additipnally, DEM Form AT-1 (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 this monitoring requirement 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 0.27 cfs Permitted Flow 0.5 MGD IWC 74 % Basin & Sub -basin (:1'B35 Receiving Stream UT Cline Creek County Gaston - f I ended • ate 2/7/95 QCL PIF Version 9/91 STANLEY WWTP 2/2/95 MAUNEY CREEK CLASS C JMN 030835 Facility requesting renewal of existing NPDES permit for expansion to 1.4 MGD.

He said that the industry is a paper manufacturer (a zipper company is also going to the system) that takes preformed bleached fibers and plastic coats it, makes a high quality paper. The plastic is highly flushable therefore ends up in the treatment plant. Plant is looking at going 100% recyclable in the next year or two. The WWTP fails fecal limit because of the amount of foam that the paper manufacture causes. They are also having a chlorine problem, trying to meet the fecal limit. Will be adding a dechlorinator. Realizes that they have failedtox test but failures are not due to metals. The Stanley WWTP will have a short term monitoring plan where they will not sample until a year before the headworks analysis is due. They will sample for the following pollutants: As, Cd, Cr, Cu, Pb, Hg, Mo, Ni, Se, Zn, BOD,COD, NH3. Because the Town will not sample enough of these parameters in the short term plan to evaluate upon next permit renewal, will recommend quarterly monitoring in the NPDES permit for the following parameters: Cd, Cr, Cu, Ni, Pb, Zn.

Recommendation: Limits for 1.4 MGD recommended in spec letter, listed above. Chronic toxicity limit. Quarterly monitoring for Cd, Cr, Cu, Pb, Ni, and Zn. ***3/7/95 Telecon from Kim Colson -- Stanley plant is having some problems and MRO is not recommending that the expansion to 1.4 MGD be allowed. At best, the plant may be allowed to expand to 1.0 MGD. In the expansion, Stanley will be using part of existing plant, but the clarifiers are very old and definitely cannot handle 1.4 MGD. Town is under some deadline with Construction Grants so the expansion is currently on hold until, the problem with the clarifiers can be resolved. The plant expansion will include doubling the aeration basin, new digesters, modification of the Cl contact tank, and the addition of a dechlorinator. Basically an extended aeration plant w/ new clarifiers. There will be no tertiary filters. Town would only add in the future if the basin management plan indicated that nutrient limits would be assigned in the next ten years. Told about the spec letter requesting 0.9 MGD and 1.4 MGD. Also, told him that I would be running new models because of the low DO upstream of the Stanley plant. Would be using lower upstream DO, instead of default of 7.55 mg/I. Said with the lower DO input into the model, previous spec limits recommended would probably not be adequate to protect water quality. Kim asked me to run model @ 0.8, 0.9, and 1.0 MGD, ASAP. He indicated that 0.8 mgd may be as large a flow as the clarifiers can handle. 3/16/95 Asked Kim about the efficiency of the plant operator and sampling equipment, he indicated that the meters used for sampling were routinely calibrated and he felt like that was not a problem. Because of documented Low DO readings both upstream and downstream of the Stanley plant, did new model runs to make sure that the limits recommended in the Feb. 1994 spec letter would still protect. In the updated model runs used upstream DO based on 3 years instream STANLEY WWTP page 3 MAUNEY CREEK CLASS C JMN 030835 monitoring data..Temp @ 75th percentile = 22, as compared to default temp of 25, background DO = 6.3 mg/1 , as compared to default DO of 7.7 mg/1, % saturation is 71.8%. Model results show that DO is protected at all flows 0.8,0.9, 1.0 MGD, but did change the effluent DO from 5 to 6 mg/1 to increase the DO minimum from 5.3 to 6 mg/l. Did not run model @ 1.4 MGD because Kim said that the plant even with the improvements that will be made will not handle 1.4 MGD unless the Town installs new clarifiers. Current economic crunch will not allow this (new clarifiers)to be included in the financipg for the upgrading of the plant. Held the loading the same for the expansion flows, lbs/day . , (limits given in the spec letter for GODS @ 0.9 MGD) ,-19-- ndg/l @ 1.0 MGD.

Effluent monitoring frequency will be 4 consecutive workdays in the year prior to the headworks analysis, probably 4 days once every five years. As I said over the phone, I do not expect metals to be a major concern. I expect that we will require Stanley to complete the first monitoring in about 12 months. From: Jackie Nowell on Wed, Jan 4, 1995 4:51 PM Subject: stanley short term mon. plan To: Joe Pearce What parameters will they monitor for under this plan? BOD, TSS, COD, MBAS, etc. I can't remember if I asked during our telecon.

Quad No.: F14SE U.S.G.S. Quad Name: Mount Holly. NC 7. Site size and expansion area consistent with application? There is limited land available for expansion and upgrading. 8. Topography (relationship to flood plain included): Moderate sloping; the WWTP is not located within the 100 year flood plain. 9. Location of nearest dwelling: One dwelling is located approximately 300 feet from the facility; however, a housing development is planned for land adjacent to the WWTP site. Page Two 10. Receiving stream or affected surface waters: Mauney Creek a. Classification: WS-IV b. River Basin and Subbasin No.: Catawba 030835 c. Describe receiving stream features and pertinent downstream uses: The receiving stream is a small stream that has moderate stream gradient with rocky/sandy bottom. The stream does appear to have positive 7Q10 and 30Q2 stream flow. General "C" classification uses downstream until the South Fork Catawba River. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. a. Volume of wastewater to be permitted: 1.4 MGD (ultimate design capacity) b. Current permitted capacity of the wastewater treatment facility: 0.500 MGD c. Actual treatment capacity of the current facility (current design capacity): 0.500 MGD d. Date(s) and construction activities allowed by previous Authorizations to Construct issued in the previous two years: N/A e. Please provide a description of existing or substantially constructed wastewater treatment facilities: The existing WWT facilities consist of a bar screen, mechanical screening (inoperable), aeration basin with mechanical aerators, secondary clarifiers, chlorine contact tank, aerated sludge storage basin, aerobic sludge digester, and sludge drying beds (inoperable). f. Please provide a description of proposed wastewater treatment facilities: Proposed WWT facilities consist of two aerobic sludge digesters, an aeration basin with mechanical aerators, mechanical bar screen, and dechlorination. The existing sludge holding basin will be reduced to accommodate the new aeration basin. The existing aerobic digester will be abandoned. The existing influent screening and flow measuring units will be abandoned. g. Possible toxic impacts to surface waters: The Town receives industrial wastewater from several industries. Walkisoft USA did have some impacts at the WWTP and possibly the receiving stream. The industry has since constructed pilot wastewater pretreatment facilities. Since the pretreatment facilities have been constructed, there have been fewer reported impacts at the WWTP. Permanent pretreatment facilities are expected to be completed in the near future. Page Three h. Pretreatment Program (POTWs only): The Town is scheduled to have an approved pretreatment program by December 31, 1994. 2. Residuals handling and utilization/disposal scheme: a. If residuals are being land applied, please specify DEM Permit No.: WQ0002081 Residuals Contractor: AMSCO, Inc. Telephone No.: (910) 766-0328 b. Residuals stabilization: PSRP X PFRP Other c.

Is this facility being constructed with Construction Grant Funds or are any public monies involved? N/A Special monitoring or limitations (including toxicity requests: The Instream Assessment Unit should consider a higher D.O. limit since levels of D.O. in the receiving stream have been reported less than 5.0 mg/l. This condition may also affect the ability of the stream to accept additional wastewater. 3. Important SOC, JOC or Compliance Schedule dates (Please indicate): N/A 4. Alternative Analysis Evaluation: Spray Irrigation: N/A Connection to Regional Sewer System: N/A Subsurface: N/A Other disposal options: N/A 5. Air quality and/or groundwater concerns or hazardous materials utilized at this facility that may impact water quality, air quality, or groundwater: There are no known air quality, groundwater, or hazardous materials concerns. Page Four 6. Other Special Items: N/A PART IV — EVALUATION AND RECOMMENDATIONS The permittee, Town of Stanley, has applied for permit modification to expand the WWTP to 1.4 MGD. The facility was originally constructed with a capacity of 1.4 MGD. The Town has since modified the WWTP to reduce the capacity since a significant industrial user went out of business. The Town now has added several industries and wishes to expand the WWTP. The proposed expansion of the WWTP may not be adequate to treat 1.4 MGD. Additional clarification and chlorine contact time may be required. Any expansion would also require the Town provide dual chlorine contact tanks. The facility may not have adequate area where the existing units are located for an additional clarifier or chlorine contact tank. To expand these units, the facility may have to abandon the old units and pump from the aeration basin to a new location onsite. The Town may not have adequate funds to pay for these additional facilities. It is recommended that the Town provide design calculations for the clarifiers and chlorine contact tank before modification of the NPDES Permit is granted. Any flow modification should be limited to their design capacity since these facilities will not be replaced. Signature of report preparer ,D, /7-1, Water Quality gional Supervisor Date
