No Permit Writer: Natalie V. Sierra Subbasin: 03-08-01 Date: September 26, 2003 Drainage Area (mi): 96 • w' Lat. 350 25' 28" N Long. 81' 10' 45" W 7Q10 (cfs) 6.6 30Q2 (cfs) 33.4 Average Flow (cfs): 169 IWC (%): 19% BACKGROUND The Town of Lake Lure WWTP is a Grade II physical/chemical plant with 0.995 MGD design flow. The permit was originally issued on November 4, 1998 and expired on August 31, 2003. The Permittee submitted EPA Form 2A on December 12, 2002 in order to request renewal of the permit. Since the flow of this plant is below 1.0 MGD and consists entirely of domestic flow, the extended effluent testing and second species toxicity tests do not apply. The Permittee was, however, missing data for dissolved oxygen, TKN, nitrate and nitrite, oil and grease, total phosphorus and total dissolved solids. These will be requested in the draft permit cover letter. The regional office notes that the Town has severe problems with inflow/infiltration (1/I); this is attributed to the fact that a large portion of the collection system is below full pool of the lake. The Town has an ongoing I/I program to address these problems. The Permittee has not requested any changes to the existing permit nor does the regional office note any changes of significance in the previous permit term. Due to problems with Total Suspended Solids (TSS)compliance, the Town will be undertaking a project to improve solids removal. An Authorization to Construct for this project has not yet been issued. Instream Monitoring, Verification of Existing Conditions and DMR Data Review This facility discharges to the Broad River in subbasin 03-08-01. The Broad River is classified C waters at the discharge point and is not on the 2002-303(d) list. The facility is not required to collect instream data, so no instream review was performed for this renewal. DMR data from January 2001 through July 2003 were reviewed. Data for conventional parameters are summarized in Table 1. Table 1. NCO025381 Conventional Data (January 2001-July 2003) This facility is also required to collect data for total residual chlorine, total nitrogen, total phosphorus, and ammonia nitrogen (NH3-N). In DMRs reviewed for this renewal, no total nitrogen and total phosphorus data were reported, a violation of the permit. The ARO was notified (and this omission was noted in the draft cover letter). Total residual chlorine and NH3-N are summarized in Table 2. Table 2. NCO025381 Nutrient Data (January 2001— July 2003) Correspondence The Asheville Regional Office (ARO) conducted several site visits during this permit term to evaluate compliance. Operational deficiencies, particularly relating to solids management, are noted in these compliance evaluation inspection reports. A review of the two-year correspondence history for the Town of Lake Lure revealed that six NOVs were issued for TSS effluent limit violations. An August 2002 compliance inspection report and a July 2003 Notice of Violation both noted that the Permittee needs to implement a more aggressive solids management plan. The regional office attributes solids problems to a lack of solids management, solids removal equipment, and having only one final clarifier. The region also notes that the Town's severe inflow/infiltration (I/1) problems result in a low strength wastewater that is difficult to treat with an activated sludge system. PERMITTING STRATEGY Waste Load Allocation (WLA) The Division prepared the last WLA for the previous permit renewal. The previous and current effluent limits were based on guidelines and water quality standards. The Division has judged previous parameters and limits to be appropriate for renewal with some exceptions. Weekly average ammonia limits based on a 3:1 ratio with the monthly average will be implemented in this permit. This is a new statewide policy that resulted from EPA requirements. The resulting summer weekly average limit will be 12.9 mg/L. SUMMARY OF PROPOSED CHANGES In keeping with Division policies, the following will be incorporated into the permit: New summer weekly average ammonia limit PROPOSED SCHEDULE FOR PERMIT ISSUANCE Draft Permit to Public Notice: October 29, 2003 Permit Scheduled to Issue: December 15, 2003 Attachment(s): DMR data summary NPDES DIVISION CONTACT If you have questions regarding any of the ab ve information or on the attached permit, please contact Natalie Sierra at (919) 733-5083 ext. 55 L rvn �ATkL-tr, s 0-P_�A- REGIONAL OFFICE COMMENTS Staff report dated January 28, 2003 — no adverse comments (other than that listed in this fact sheet).

Other Special Items: N/A PART IV - EVALUATION AND RECOMMENDATIONS A large percentage of the collection system is below full pool of the lake. Consequently, the Town's untreated wastewater lacks sufficient strength to allow for typical activated sludge wastewater treatment. The treatment process is aluminum chloride and chlorine addition at the head of the treatment facility. It is recommended the permit be renewed as a Grade II Physical/Chemical. The filtration unit shown on the schematic is not in service. This equipment has never operated efficiently and has not been in service for many years. Otherwise, the flow schematic is correct as submitted in the application package. / _ Signa ure of Report Prepare , Da Quality -Regional Supervisor -5- �m INFLUENT FLASH MIX CHEMICAL ADDITI FILTRATION UNIT INFLUENT BAR SCREEN AND FLUME AEROBIC DI GESTOR SEDIMENTATION BASIN FLOCCULATION FLOW METER SLUDGE CLARIFIER \-SLUDGE ,-SLUDGE PUMPS TOWN OF LAKE LURE WASTEWATER TREATMENT PLANT WWTP SCHEMATIC DISCHARGE SERIAL NO. 001 DECEMBER, 2002 TOWN OF LAKE LIFE Office of the Town Manager Incorporated 1927 December 12, 2002 Mrs. Valery Stephens NCDENR/Water Quality/ Point :Source Branch 1617 Mail Service Center Raleigh, North Carolina 27699-1617 RE: NPDES Permit No-NC0025381 Town -of Lake Lure WWTP Rutherford County, North Carolina Dear Mrs. Stephens: The Town of Lake Lure is hereby requesting renewal of our existing NPDES Permit No. NCO025381 for the Town's existing wastewater treatment. plant.

There have been no additions or improvements at the WWTP since the last renewal was issued. Based on our engineer's conversation with your agency, it is our understanding that the testing requirements described in Mr. Charles Weaver's letter dated July 2, 2002 regarding the permit renewal do not apply to our facility because the permitted capacity of the plant is less than one million gallons per day. We are, therefore, not enclosing the Priority Pollutant :Analyses or toxicity tests requested in the letter.
