Also requesting expansion flow of 7 MGD at relocation of outfall into the French Broad River below the confluence of Mud Creek. Because of concern about overallocation of assimilative capacity on Mud Creek, a QUAL2E model was run on Mud and Clear Creeks. All new and expanding discharges should implement treatment consistent with that required for Hendersonville, BOD5=10, NH3=2, DO=6. This strategy is to encourage regionalization.of wastewater treatment and reduce the proliferation of small package plants.

Facility Name Hendersonville WWTP Permit # NC0025534 _ 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 _35 % (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 _NOV FEB MAY AUG .. 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 17 cfs Permitted Flow 6 MGD IWC 35 Basin & Sub -basin FRB02 Receiving Stream MUD CREEK County HENDERSON QCL P/F Version 9/91 TOXICANT ANALYSIS Facility Name HENDERSONVILLE WWTP NPDES # NC0025534 '; Qw (MGD) 6 7Q 1Os (cfs) 17 IWC (%) 35.36i Rec'ving Stream Mud Creek • Stream Class C FINAL RESULTS E Cyanide Max.

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 17 cfs Permitted Flow 3.2_ MGD IWC 22 % Basin & Sub -basin FRB02 Recommended by: Receiving Stream _ MUD CREEK County HENDERSON Date 5/9/95 QCL P/F Version 9/91 TOXICANT ANALYSIS . 4 . yi. 44, h r ik's") /te-L, Sydr. . �irt+d4 s. 1'"t L'.nfi�1J( ffr?Uf a!

Per FRB basinwide management plan: Due to the continued Poor biological quality rating and the proliferation of dischargesm, a field calibrated model was developed for Mud Creek in 1992. Discharges to Mud Creek, Allen Branch, Cherry Branch, Featherstone Creek and Clear Creek were included in the model. New and expanding discharges to this watershed will required to meet advanced treatment with limits of 10 mg/1 BODS and 2 mg/1 NH3-N. The Hendersonville WWTP dominates the assimilative capacity of Mud Creek below Clear Creek. Based on the results of the QUAL2E, Hendersonville started consideration of relocation to the French Broad River. It also is recommended that Hendersonville and Henderson County should work together to reduce the total number of discharges in this system. ARO concerns: Per staff report , there are several issues that should be reviewed before ARO will make final recommendation on the relocation and expansion to the French Broad River. 1) Discharge point should be provided on the map of plant site. * In spec request to DEM in 11/93, discharge site was designated on French Broad River just below the confluence of Mud Creek. 2) Feasibilty of connection to MSD-Bunccombe Co. should be investigated. 3) The contribution of GE, which has been issued an industrial permit should be included in the application. 4) Portions of the facility seems to be located within the 100 year flood plain and this needs to be clarified. Review of compliance data : no violation of limits, system still has @ 3.2 MGD design flow not @ 6 MGD. Stormwater sampling indicates thatn some permitted parameter metals are being contributed by inflow and infiltration of stormwater entering the sewer syatem. The parameters are Aluminum, Iron, and Zinc. Stormwater (SW) Data from East(E), South(S), North(N), and West(W) in µg/1 is as follows: SWE SWS SWN SWW Aluminum 878 1100 780 885 Iron 1340 2270 1720 1370 Zinc 43 37 16 36 Silver - - 11 No instream DO problems, however, fecal levels exceed tthe state standard of 200/100m1. Previously recommended limits @ 3.2, 6 , and 7 MGD will be renewed in the new WLA. Metals limits will be assigned per current toxicity analysis procedure. SEE ATTACHED SPREADSHEETS.

" W Don Sa SUBJECT: Revisions to the Hendersonville Environmental Assessment Hendersonville WWTP NPDES No. NC0025534 Henderson County The Instream Assessment Unit has reviewed the revision to the environmental assessment for the City of Hendersonville's Waste Water Treatment Plant relocation. Most of my comments have been addressed in this revision. The exceptions are discussed below. On page 57, #13. Toxic Substances indicates that no toxic substances will be accepted at the proposed WWTP. The existing facility has a pretreatment program which includes a facility with categorical limits. Presumably, the General Electric wastewater stream would be subject to the pretreatment program as well. The EA should discuss the pretreatment program and perhaps state that the WWTP will not accept wastestrearns which would detrimentally impact the operation of the WWTP or cause a water quality violation in the receiving water. In addition, the EA should address the effect of relocation on effluent limits for toxics. Though this revision includes citizen monitoring data, no ambient data or self -monitoring data have been reviewed. The report should at least mention the data which has been summarized in the draft Franch Broad River Basin Plan. The EA should address the feasibility of nondischarge alternatives such as land application. Thank you for this opportunity to review and comment. If you have questions or concerns, please call. cc: Asheville Regional Office SOC PRIORITY PROJECT : No IF YES, SOC NUMBER TO: PERMITS AND ENGINEERING UNIT WATER QUALITY SECTION ATTENTION: Dana Bolden DATE: June 23, 1994 NPDES STAFF REPORT AND RECOMMENDATION COUNTY Henderson PERMIT NUMBER NC0025534 PART I - GENERAL INFORMATION 1.

Site size and expansion area consistent with application? yes Yes No If No, explain: 8. Topography (relationship to flood plain included): Most of the 104 acre site has a relief of less than 20 feet. Site is a bottom land flood plain. A survey map obtained states that 65 acres are within the 100 year flood plain. However, the FEMA Flood Boundary and Flood Way Map dated March 1, 1982, indicates that approximately 65 acres are within the flood way and approximately 99 acres are within the 100 year flood elevation. 9. Location of nearest dwelling: 1000 feet. Page 1 g. 10. Receiving stream or affected surface waters: French Broad River a. Classification: WS-IV b. River Basin and Subbasin No.: 04-03-02 c. Describe receiving stream features and pertinent downstream uses: The French Broad River at this location is approximately 100 feet wide with a flood plain up to one mile wide and with a gradient of approximately 3 feet per mile. Downstream uses include fish and wildlife propagation, fishing, hunting, agriculture, secondary recreation, and proposed water supply. The proposed intake for the City of Asheville's water supply is located approximately 10 miles downstream. PART II - DESCRIPTION OF DISCHARGE AND TREATMENT WORKS 1. a. Volume of wastewater to be permitted 7.0 MGD (Ultimate Design Capacity) b. What is the current permitted capacity of the Wastewater Treatment facility? none at this site. c. Actual treatment capacity of the current facility (current design capacity none at this site. d. Date(s) and construction activities allowed by previous Authorizations to Construct issued in the previous two years: none at this site. e. Please provide a description of existing or substantially constructed wastewater treatment facilities: none at this site. f. Please provide a description of proposed wastewater treatment facilities: Per application: "Proposed facilities will consist of primary screening and grit removal, followed by biological treatment using the activated sludge method in two oxidation ditches. Solids will then settle in and will be removed from three secondary clarifiers. Wastewater will be disinfected by the use of chlorine gas and will be dechlorinated prior to discharge. Cascade aeration is the method of aerating wastewater immediately before discharge." Possible toxic impacts to surface waters: Chlorine, ammonia, cleaning compounds, metals, various organic chemicals. h. Pretreatment Program (POTWs only): in development approved YES should be required not needed Page 2 2. Residuals handling and utilization/disposal scheme: Hendersonville has a current land application permit, however, the farmer is not currently allowing sludge application. The Henderson County landfill is accepting a small amount of their sludge to apply to disturbed areas of the Landfill at agronomic rates. Additional disposal in the near term will require hauling to a permitted facility outside of the county. Clearly, additional sludge disposal alternatives are needed. a. If residuals are being land applied, please specify DEM Permit Number WQ0004319 Residuals Contractor Changes from year to year. Telephone Number n/a b. Residuals stabilization: PSRP PFRP OTHER anaerobic digester c. Landfill: Henderson County Landfill d. Other disposal/utilization scheme (Specify): 3.

Alternative Analysis Evaluation: Has the facility evaluated all of the non -discharge options available. Please provide regional perspective for each option evaluated. Spray Irrigation: insufficient land available Connection to Regional Sewer System: Feasibility of connecting to the Metropolitan Sewerage District should be investigated. Subsurface:. not feasible Other disposal options: 5. Other Special Items: PART IV - EVALUATION -AND RECOMMENDATIONS 1. The discharge point location should be provided on the map of the plant site. The coordinates of the discharge point in the permit application should be corrected. 2. The feasibility of connecting to the Metropolitan Sewerage District should be investigated. 3.. The application does not include the contribution of General Electric, which has been issued an industrial user permit by the City. 4. A map obtained subsequent to receiving the application indicates that 65 of the 104 acres are within the 100 year flood elevation, which is in conflict with the March 1, 1982 FEMA flood map. This should be clarified and the application should specify how the facilities will be located in relation to and protected from the 100 year flood. It is recommended that additional consideration be given to floods in excess of the 100 year frequency due to the significance of the potential damage to facilities and impact on the ability of the plant to recover from a flood situation. Further recommendations will be made pending receipt of the above information. If you have any questions, please call. a4AL(A) L)tc, 5er Qual,4 ty egional Supervisor /7 Date Page 4
