Yes No If no, which parameters cannot be met? Would a "phasing in" of the new limits be appropriate? Yes No If yes, please provide a schedule (and basis for that schedule) with the regional office recommendations: If no, why not? Special Instructions or Conditions Wasteload sent to EPA? (Major) (Y or N) (If yes, then attach updated evaluation of facility, including toxics spreadsheet, modeling analysisif modeled at renewal, and description of how it fits into basinwide plan) Additional Information attached? (Y or N) If yes, explain with attachments. Facility Name Tabor City Waste Water Treatment Plant Permit # NC0026000 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 90 % (defined as treatment two in the North Carolina procedure document). The permit holder shall perform guartertv 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 Mar., Jun., Sept., and Dec. 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 0.0 cfs Permitted Flow 1.1 MGD IWC 100 % Basin & Sub -basin 03-07-57 Receiving Stream tributary to Grissett Swamp County Columbus QCL P/F Version 9/91 Recommended b = Farrell Keoigh Date a mot, %°tst, Facility Name: Permit Number: Engineer: Subbasin: Receiving Stream: USGS quad #: Request Number: Date: Expiration date: Tabor City Waste Water Treatment Plant NC0026000 Bolden 03-07-57 Town Canal [ unnamed tributary to Grissett Swamp ] K23NE 7758 2/22/94 6/30/94 Existing WLA checked: Staff Report: Topo checked: USGS Flows confirmed: PIRF / APAMS: IWC Spreadsheet: Stream Classification: Nutrient Sensitivity: Instream Data: x x x map attached na nr nr x not a Pretreatment facility facility already at 5 and 2 x Downstream site may be too far away; will contact region to see if closer site available Brief of WLA Analysis Previous WLA's 1976: first issuance and limits of 5 and 2 with a fecal limit of 200 / 100 ml and pH of 6 - 8.5 1980: fact sheet not dated, but looks like a re -issuance with same limits 1983: re -issued with same limits, (summer only), but fecal coliform now is 1,000 / 100 ml 1984: re -issued with winter limits, (still advanced tertiary and 1,000 / 100 ml fecal limit) 1989: re -issued with same limits and a recommendation of removal The facility is undergoing extensive upgrading, (per conversation with Steven West; Wilmington]. Due to this money being put into the plant maintenance, the Region felt that now was the time to require a chlorine limit. The minor modification on the WLA is somewhat of a misnomer; the facility is adding a flow -equilibrated chlorine feed system, thus no change in the NPDES Permit is requested, therefore the addition of a chlorine limit would not be SOP. Since the Region concurs that this additional limit would be pertinent and the facility did not object to its addition I will require a 28.0 µg/I limit. This limit will probably have the added benefit of giving the operator a mechanism for requesting moneys to fulfill it.. Staff Report indicates facility has trouble meeting limits when flows exceed 0.7 mgd. Only DMR data we have when flows get that high is for January, 1993 and ammonia was violated during that month. Probably I and I was the reason for this excessive flow since most other months are well below 0.7 mgd. Since the facility is putting moneys into plant upgrades, (including I and I) then we can only assume that limits should be met in the future.... The 1989 WLA recommended facility remove discharge; only alternative would be land application; this area is swampy, therefore the surficial aquifer would be hydrologically connected to such application. Also, no other township is close enough for Regionalization... 1A/ 4 ('("AMA H Per NUCC, facility is a Major, therefore the toxicity test will remain.... Due to the low velocities in this swamp system, I checked on possible alternative downstream monitoring locations. The current downstream location, Iron Hill Bridge, is approximately 5 miles downstream of discharge point. There is another location approximately 75 yds below the discharge point which may reflect the localized impacts due to low velocities. This proposed second downstream monitoring location will also discount the additional flow present from the swamp discharge at Iron Hill Bridge. Early modeling analysis indicated a DO sag at milepoint 0.8, but a later re -modeling of the discharge indicated the sag was at 2.4 miles below the discharge. Unfortunately, both these models were run with a zero 7Q10, thus reliability is questionable. Since our current model techniques do not present these swamp systems effectively, this additional instream monitoring should prove beneficial for later basin management analysis. 701 l Ha, - Cl.p Na, SeMohlenl R„r S• amp GYM S•r S,mneeJ Nu, Gore La 41144,1e Ilene Pen Ner Bad Bee /Jared H4r Ba, Rer noy 1 one).
