Hunt, Jr., Governor Bill Holman, Secretary Kerr T. Stevens, Director October 1, 1999 The Honorable Tom Woodlee, Mayor Town of Franklin 188 W. Main St. Franklin, North Carolina 28734 AVA NCDENR Subject: Speculative Limits for Franklin WWTP NPDES Permit No. NC0021547 Macon County Dear Mayor Woodlee: This letter responds to the request of Mr. Dana Bolden of McGill and Associates for speculative effluent limits for the expansion of the Franklin WWTP. The design flow of 3.3 MGD was targeted. The staff of the NPDES Unit of the Point Source Branch has reviewed this request. Please be advised that response to this request does not guarantee that the Division will issue an NPDES permit to discharge treated wastewater into these receiving waters. It should be noted that new and expanding facilities, involving an expenditure of public funds or use of public (state) lands, will be required to prepare an environmental assessment (EA) when wasteflows: 1) exceed or equal 0.5 MGD, or 2) exceed one-third of the 7Q10 flow of the receiving stream. DWQ will not accept a permit application for a project requiring an EA until the document has been approved by the Department of Environment and Natural Resources and a Finding of No Significant Impact (FONSI) has been sent to the state Clearinghouse for review and comment. The EA should contain a clear justification for the proposed facility and an analysis of potential alternatives, which should include a thorough evaluation of non -discharge alternatives. Nondischarge alternatives or alternatives to expansion, such as spray irrigation, water conservation inflow and infiltration reduction or connection to a regional treatment and disposal system, are considered to be environmentally preferable to a surface water discharge. In accordance with the North Carolina General Statutes, the practicable waste treatment and disposal alternative with the least adverse impact on environment is required to be implemented. If the EA demonstrates that the project may result in a significant adverse affect on the quality of the environment, an Environmental Impact Statement would be required. The Division of Water 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Telephone (919) 733-5083 FAX (919) 733-0719 An Equal Opportunity Affirmative Action Employer Internet: http://h2o.enr.state.nc.us/ Speculative for Franklin WWTP Page 2 Quality's Planning Branch can provide further information regarding the requirements of the N.C. Environmental Policy Act. The Town of Franklin will continue to discharge into the Little Tennessee River (Upper segment of Lake Emory). This segment of the river has a stream classification of C. The best usage of waters is for aquatic life propagation and maintenance of biological integrity, including fishing and fish, wildlife, secondary recreation, agriculture and any other usage except for primary recreation or as a source of water supply for drinking, culinary, or food processing purposes. The discharge point in the Little Tennessee River has a drainage area of 299 square miles, with an estimated average flow of 807 cfs, a summer 7Q10 of 160 cfs and a winter 7Q10 of 202 cfs. Based on available information, the tentative effluent limits for oxygen consuming constituents of the Franklin WWTP at the expansion flow of 3.3 MGD are included on the attached effluent sheet. The requirement for quarterly chronic toxicity testing will remain a condition of the NPDES permit. An individual chronic toxicity limit for 3.3 MGD will be 3.0%. A complete evaluation of limits and monitoring requirements for metals and other toxicants will be addressed at the time of formal permit application. The existing monitoring requirements for metals are listed, however the mercury limit of 0.4 µg/1 that may be required at 3.3 MGD has been included. The Division of Water Quality is requiring chlorine limits for all new or expanding dischargers proposing the use of chlorine for disinfection. The process of chlorination/dechlorination or an alternate form of disinfection, such as ultraviolet radiation, should allow the facility to comply this requirement. Final NPDES effluent limitations will be determined after a formal permit application has been submitted to the Division. If there are any additional questions concerning this matter, please feel free to contact Jackie Nowell of my staff at (919) 733-5083 (ext. 512). Repectfull David A.

NC0021547 Franklin WWTP Little Tennessee River (Lake Emory) C 040401 Speculative Request Engineer has requested spec limits for an increase of wasteflow to 3.3 MGD. S. Pellei issued current permit at 1.65 MGD in March 1998. The facility has existing secondary limits in addition to fecal conform at 200/100m1, chlorine at 28 ug/l, and mercury at 0.7 ug/l. Also, there is effluent monitoring for Cd, Cr, Cu, Cn, Ni, Pb, Zn, and Ag. A quarterly chronic pass/fail toxicity test @ 1.6% in MAR JUN SEPT DEC, is also a permit requirement. Franklin will have to provide justification for the request to 3.3 MGD, a doubling of the design of 1.65 MGD. Currently the average flow is less than 1.1 MGD. Notes indicate that based on the projected growth pattern, they will be at 80% capacity in 2009-2010. By 2019, they will exceed plant capacity. The request for doubling of capacity may include projections for industry and the continued growth pattern. Franklin had an 18% increase in population between 1980 and 1994. The facility discharges into the Little Tennessee River (Upper Lake Emory) located in the Little Tennessee River Basin and is classified as C. This river segment is not listed on the 1998 303d list for impaired streams. From the 1997 Little Tennessee River Basinwide Management Plan, Chapter 4, p. 4-19. Lake Emory is a run of the river impoundment on the Little Tennessee River. A 1988 survey noted eutrophic conditions with high suspended solids, chlorophyll a, and nutrients. The 1994 investigation noted a slight decrease in suspended solids and a more dramatic increase in nutrients and chlorophyll a. Field observations noted that the lakes looked as though it was filling in and becoming a wetland, with sediment bars formed and plant life growing on the bars. During the 1994 investigation, Lake Emory obtained a low TSI score indicating oligotrophic conditions. This between year change may be due to wet weather conditions prior to sample collection in 1994, nutrient uptake by plants on the sediment bars, the closing of a large farm upstream, or the expansion and upgrade of the Franklin WWTP. Monitoring on the status of Lake Emory will be continued. Effluent Data Review Data from March 1996-July 1999 was retrieved via the compliance monitoring system. The Franklin plant appeared to be fairly well operated. There have been only a few exceedances of permit limits, i.e. TSS violations in Feb. and June 1999 and a fecal violation in Nov. 1996. NC0021547 Franklin WWTP Page 2 It should be noted that the compliance monitoring system does not indicate a mercury limit of 0.7 ug/l, and it would seem that the limit has been violated based on some monthly averages reported. There needs to be some verification of 1999 data reported. Monthly data values for mercury of 1.45 ug/l, 2.56 ug/1 and 7.2 ug/1 have been recorded and these would be excessive violations of the 0.7 ug/l limit. In addition, there have been some reported silver values that are greater than the allowable concentration of 3.7 ug/l. Since this is an action level, cannot assign a limit at this time, but will recommend continued monitoring. Recommend continued monitoring of all metals, and will do a complete reasonable potential analysis upon formal expansion request to 3.3 MGD. Toxicity Test Results The facility has consistently passed the Chronic Pass/Fail test at 1.6% since 1995. There has been only one FAIL that occurred in Sept. 1997. A PASS immediately followed it later that same month. (One LATE in MAR 1995.) At 3.3 MGD, the new toxicity increase will increase to 3.1%. Oxygen Consuming Waste Due to the receiving stream being the upper part of a lake, DWQ does not have an adequate modeling tool. However, BPJ based on the size of the river and small IWC, would indicate that secondary limits for BOD5 and TSS at 3.3 MGD would still protect the receiving stream. See letter for specific limits and requirements per the speculative expansion to 3.3 MGD.

The discharge location will remain the same. Additional treatment units similar to the existing units will be constructed to accommodate the additional flow. The Town is in the process of preparing and environmental assessment and securing funding for this project. Therefore, your timely response to this request would be greatly appreciated. If you have any questions or need additional information, please do not hesitate to contact me. Sincerely, McGILL ASSOCIATES, P.A. 41,1f, DANA J.
