Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity (AT) test form indicating the facility name, permit number, pipe number, county, and the month/year of the report with the notation of "No Flow" in the comment area of the form. The report shall be submitted to the Environmental Sciences Branch at the address cited above. 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 the permittee fail to monitor during a month in which toxicity monitoring is required, 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 Water Quality indicate potential impacts to the receiving stream, this permit may be re- opened and modified to include alternate monitoring requirements or limits. Permit No. NC0063321 SUPPLEMENT TO EFFLUENT LIMITATIONS AND MONITORING REQUIREMENTS (Continued) SPECIAL CONDITIONS NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES 7 1( DIVISION OF WATER QUALITY%� March 18, 1998 iA' 23 i998 MEMQRANDUM TO: A. Preston Howard, Jr., Director FROM: M. Steven Mauney, Meeting Officer . 2-7 SUBJECT: Findings and Recommendations(s) in the Matter of NPDES Permit NC0063321 Cashiers WWTP, Tuckaseigee Water and Sewer Authority Jackson County D DIV. OF WATER QUALITY DIRECTOR'S OFFICE A►'d fo0ti POINT SOURCE BRANCH As directed by you, I have conducted a Public Meeting concerning whether to issue a NPDES Permit to Tuckaseigee Water and Sewer Authority for the continued operation of the Cashiers WWTP. This meeting was held at the Blue Ridge School in Cashiers on January 12, 1998, at 7:00 p.m. Application Abstract On January 27, 1997, Mr. Stan Bryson, Wastewater Plant Operations Superintendent applied for renewal of the Cashiers WWTP Permit. The Permit previously issued January 15, 1993, and modified on March 31, 1993, as well as on November 30, 1993, authorized the continued discharge of 0.1 MGD to an unnamed tributary to the Chattooga River which is classified B-Trout ORW waters in the Savannah River Basin. The permit also contained a limits page for 0.2 MGD which would apply upon expansion of the WWTP. The stream has a 7Q10 of 0.5. CFS and a 30Q2 of 1.1 CFS. Copy of a USGS topo map is located in Attachment I for your convenience. Meeting Summary DWO 1. In addition to the Water Quality Staff, Mr. Darryl Williams and Mr. Jim Adcock of EPA, Atlanta, there were 18 registered persons in attendance at the meeting. Of these 18 persons, 7 expressed comments opposing issuance of the permit as drafted. 2. Mr. Jeff Myhra, with DWQ gave a brief presentation of our permitting procedures and rationale for renewing the NPDES Permit. See Item 3.f. for more comments by Mr. Myhra. 3 Issues raised: A. The common theme that was repeated by most speakers was their concern for odors and noise at the plant site which is located in a residential area. B. Ms. Peg Jones, President, Save Our Rivers, Inc. requested the facility study their non - discharge options. She noted that funding assistance was being requested from the Clean Water Trust Fund. C. Mr. Buzz Williams, Executive Director, Chattooga River Watershed Coalition expressed concerns for odor, and requested protection of the Chatooga River which he called a premiere waterway and a national treasure. D. Ms. Jane Gorsline, whose home is about 300'-400' from the plant blowers, again stressed her concern for noise and odor. E. Mr. Ray Mortensen, V.P. Southeast Region, (NC, SC, GA) Trout Unlimited said that his group is generally opposed to discharging systems and would be more opposed if the facility was in violation. F Mr. Jeff Myra noted in his presentation that, "The Division will include a special condition in the permit renewal that outlines the requirement to install an automatic backup power system to operate the treatment components during power failures. At the time of permit renewal a compliance deadline not to exceed 90 days will be negotiated with the Permittee for completing the installation of the automatic backup power system." Mr. Myra also stated that, "The Division will recommend enclosing the blower units or installing mufflers on the units upon expansion of the facility." Other Information On January 13, 1998, Mr. Forrest Westall told Mr. Jerry King, Director, Tuckaseigee Water and Sewer Authority about the proposed permit condition for installation of an automatic power switch -over device within 90 days. They also discussed the possibility of enclosing the blowers as was done at the Cullasaja Plant. According to Mr. King, the plant expansion could occur in 2-4 years. Findings 1. The basic issue involved in these matters is whether you, as Director of the Division of Water Quality, should approve, deny or modify the NPDES permit in question. The decision making criteria has been established in Title 15A NCAC Chapter 2, Subchapter H., Section .0112(b) and N.C. General Statute 143-215.1 (b). 2. This application for permit appears to be proper, public notice of intent to issue and subsequent notice of public meeting have been in keeping with regulatory requirements. 3. The receiving stream for this discharge is appropriately classified with applicable water quality standards. The discharge limitations in the draft NPDES permit were determined using the Division's approved waste load allocation methodology. 4. Visual observations made on the day of the meeting at the plant site, revealed no problems with odors and a moderately high level of noise from the blowers. Visually the stream looked fine. 5. Plans for expansion of the Cashiers WWTP to 0.2 MGD were submitted January 30, 1997, by Mattern and Craig, Consulting Engineers. Mr. Myhra asked for additional information on this project. Discussion - One hearing speaker suggested that the facility study their non -discharge options. As this is an existing treatment plant that is largely in compliance with its NPDES Permit, and discharging to a stream with a positive flow, there is no justification for them to pursue a non -discharge approach. While it may be coincidental that the plans for the expansion were submitted at the time of the permit renewal and while there may be benefits to providing additional capacity at this site, it now appears that Tuckaseigee Water & Sewer Authority does not plan to immediately begin the expansion.. Instead of waiting until the plant expansion, certain steps can be taken now to improve the plant reliability and reduce the potential for odors. As Mr. Myhra stated at the meeting, the permittee should install automatic power switch -over equipment within 90 days of permit issuance. The issue of noise control is very crucial to the nearby residents who live on large lots surrounded by mature trees in a very tranquil setting. The permit should be issued with a schedule to require a proposed design for sound proofing this plant within three months and installation with six months. This would allow the permittee the time to incorporate the soundproofing in their plant expansion if they were to decide to proceed with the expansion. Recommendation - It is recommended that the permit be reissued with the following conditions: 1. The permit should be conditioned to require the automatic power switch -over device within 90 days. 2. The permit should also be conditioned to require the submission of the proposed design of an enclosure for the blowers or other noise reduction equipment within three (3) months of permit issuance and final installation within six (6) months. cc: Coleen Sullins Dave Goodrich Central Files Attachment I ROAD CLASSIFICATION PRIMARY HWY HARD SURFACE • • • • 1111111111.11.1111 SECONDARY HWY HARD SURFACE•••• LIGHT -DUTY ROAD, HARD OR IMPROVED SURFACE UNIMPROVED ROAD.•-- = _ = Latitude 35°06'13" Longitude 83°06'24" Map # G6SE Stream Class Sub -basin 03-13-01 B-Trout ORW Discharge Code(s) Receiving Stream Design Q 0.2 MGD 01 UT to Chattooga River Permit expires 8/31/02 •�:wvza�tts •naaxcsra-.xs..ea Tuckaseigee Water & Sewer NC0063321 Jackson County Cashiers WWTP Attachment H Al-t-rhetry (Rivutc_ 4-1/16 TiFe7e-r---sead1,19 1>o voti Nicp) .)to q-bRs It ay Mo Tr„s Sm A a c,�.< 0 • V(---&....v-L.C....MAto • C-7-C;17-41/-r--i-P. 1 1 lDiCcn ,1 c Fr L1 i �15(51-- -rikr i) tij t-h-l7 (=Ls P6 4 ( 1P1(4 ‘1.4.0-.{. 0-44A et:0<A° A-A,o_ Rro ��. w � � .

Westal Water Quality Regio/'5upervisor A617A NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES William E. Anderso Environmental Special NPDES Permit Condition Because of continuing, and recently more acute, problems with orphan/unpermitted sewer lines, the need for a way to deal with NPDES Permittees who do not see the problem with allowing the connection of unpermitted sewer lines to their systems has become apparent. Jill Hickey of the AG's Office suggested to Forrest that a help for the situation would be to add a permit condition requiring a WQ Permit from the Division before allowing private sewer connections. Therefore, please add the following condition to the Tuckaseigee Water and Sewer Authority Permits Numbers NC0063321 (plant 3, Cashiers), NC0039578 (plant 1, Jackson County), and NC0020214 (plant 2, Sylva) also NC0021547 (Franklin) and NC0021407 (Highlands).
