Hunt, Jr., Governor Bill Holman, Secretary Kerr T. Stevens, Director April 4, 2000 The Honorable Charles R. Devinney, Mayor Town of Pittsboro P.O. Box 759 Pittsboro, North Carolina 27312 NCDENR Subject: Speculative Limits for Pittsboro WWTP NPDES No. NC0020354 Chatham County Dear Mayor Devinney: This letter is offered in response to your request for speculative effluent limits for the potential expansion of the Pittsboro wastewater treatment plant (WWTP). The plant currently has a permit to discharge 0.75 MGD of treated domestic wastewater to Robeson Creek (a tributary to Jordan Lake) in the Cape Fear River Basin in Chatham County. You and your consultant requested speculative limits for potential flow increases to 1.245 MGD and 3.0 MGD. The current permit expires February 28, 2001. We have reviewed the request and provide the following response with the enclosed speculative limits. The speculative limits presented here are based on our understanding of the proposal and of present environmental conditions. The Division of Water Quality (DWQ) cannot guarantee that it will issue the Town an NPDES permit to expand its discharge of treated wastewater into waters of the State. Nor can we guarantee that the effluent limitations and other requirements included in any permit will be exactly as presented here. Final decisions on these matters will be made only after the Division evaluates a formal permit application for the Town's discharge and notices the proposal for public comment. Environmental Assessments of New Projects and Expansions: Please be aware that you will have to evaluate this project for environmental impacts before applying for a permit modification. Anyone proposing to construct new or expanded waste treatment facilities using public funds or public (state) lands must first prepare an environmental assessment (EA) when wastewater flows (1) equal or exceed 0.5 MGD or (2) exceed one-third of the 7Q10 flow of the receiving stream. Regardless of the requested expansion flow, Pittsboro will be required to perform an EA based on the latter (criteria 2). DWQ will not accept a permit application for a project requiring an environmental assessment until the Division has 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 919 733-5083, extension 510 (fax) 919 733-0719 An Equal Opportunity Affirmative Action Employer Susan.A.Wilson@ncmail.nel • approved the EA and sent a Finding of No Significant Impact (FONSI) to the state Clearinghouse for review and comment. The Division is aware that the Town has submitted an Environmental Assessment for the project and comments from the Division have been submitted to the Town. Speculative Effluent Limits Based on the available information, tentative limits for the proposed discharge to Robeson Creek are attached. Some aspects of the speculative limits are explained below. BOD5 and NH3-N. The Pittsboro WWTP currently has BOD and NH3-N limits of 5 mg/1 and 2 mg/1, respectively. With any expansion above 1 MGD, the NH3-N limit will be reduced to 1 mg/1 (2 mg/1 winter). These limits reflect the most stringent limits to protect the minimum streamflow of 0 cfs (7Q10s). Updated streamflows provided by USGS were used in the development of the speculative limits, where appropriate. Chlorine. The Division requires chlorine limits and dechlorination 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 (as is currently used at the plant), should allow the facility to comply with the total residual chlorine limit. Chronic Toxicity Testing. The Town's chronic toxicity limit would continue to be a Pass/ Fail at 909 . Toxicant Parameters. Estimation of toxicant parameters will not be given with this speculative letter, but will be submitted as appropriate with the draft NPDES permit. However, due to the lack of dilution in the receiving stream under design conditions, any toxicant which may be limited would be based on the water quality standard. Nutrients. In reviewing the Town's request for speculative limits for a potential expansion, nutrients are a major concern. Robeson Creek is listed as partially supporting and not supporting its designated uses on North Carolina's 1998 303 (d) list. The 303 (d) list is mandated by the Clean Water Act and requires states to list any impaired water, then develop a management strategy to restore the waterbody to its designated use. One of the water quality parameters affected on Robeson Creek is chlorophyll -a, a measurement of algal activity which responds to excess nutrients; elevated levels of chlorophyll -a were found in Robeson Creek due to point source and nonpoint source contributions. As you are likely aware, the General Assembly passed House Bill 515 during the 1997 session. This bill had a direct effect on all wastewater treatment plant discharges to surface waters classified as nutrient sensitive waters (NSW). In summary, the bill specifies an average annual mass load limit for total nitrogen and/or total phosphorus, if one or both of these nutrients are deemed to be a parameter of concern. The General Assembly also passed Senate Bill 1366 in 1997, which allowed an extension date for compliance with nitrogen and phosphorus discharge limits until such time that a calibrated nutrient response model was developed in certain water bodies where an adequate model did not exist. The Town of Pittsboro is a member of the Jordan Lake Coalition, which has proposed a schedule to comply with the stipulations of Senate Bill 1366 and is not currently required to meet nutrient limits. Based on this information, the Division of Water Quality could only allow an expansion if nutrient loading remained constant throughout any expansion phase. Table 1 provides approximate concentration values and mass loading values for total nitrogen (TN) and total phosphorus (TP), if nutrient loadings were held constant with expansions to 1.245 MGD and 3.0 MGD. At the requested flow of 1.245 MGD, the Town would have difficulty complying with the estimated concentrations and loadings under the best circumstances with the technology currently available. At the requested flow of 3.0 MGD, the Division knows of no feasible treatment technology to achieve the nutrient limits listed in the table. • Table I.

Members of my staff have evaluated land use area and estimated the current load contributed by nonpoint sources. Based on this evaluation, it may be possible for the Town to expand to 1.245 MGD if the Town offsets the increased nutrient load with BMPs. The speculative effluent limits for the Town of Pittsboro's potential expansion to 1.245 MGD (from 0.75 MGD) are attached with this letter. The nutrient limits listed are for your review only. The Division and the Town, as well as the Town's consulting engineer(s), would need to have further correspondence to determine the most feasible approach, should the Town choose to expand at the current location. I would strongly encourage the Town to review any and all means to reduce the wastewater discharge. This may include, but is not limited to, reuse of wastewater and acquisition of land for spray irrigation. My staff investigated potential relocation sites for the Town's wastewater discharge, but could not determine a location where effluent limits may be less stringent. Because of the complexity of this issue, 'you may wish to meet with the Water Quality Section staff involved in the development of the speculative limits. Please contact Susan Wilson at (919) 733 — 5083, ext. 510 if you need additional information or if you would like to schedule a meeting. Sincerely, An", ttre‘ H.

Re: Reclassification of Treatment Plant Request for Speculative Waste Load Allocation Engineering Alternatives Analysis Report for Expansion of NPDES Permit by .495 MGD Long Range Growth Considerations: Dear Mr. Montgomery: The purpose of this letter is to update you and your staff and to provide information on the four items referenced above. 1. Rgcl.assification of Treatment Plant Effective April 1, 1999, the NC Administrative Code classifies all activated sludge plants with permitted flows between .50 MGD and 2.5 MOD as Grade III facilitie, unless a biological nutrient removal (BNR) process is utilized (your plant does not use BNR). Therefore, your plant should now be a Grade III. The problem I have discovered is that Department of Water Quality (DWQ) apparently does not have a plan in place to officially notify the plants that will change classifications due to the new rules. I have called both the NPDES Permit Unit and the Certification Commission to inquire how the reclassification will be accomplished, but I have not received an answer. I have drafted a written inquiry on behalf of the Town (copy enclosed) that I will submit after you have reviewed and approved same. Hopefully this will prompt DWQ to officially notify the Town that the treatment plant is a Grade III. 2. Request,9r Speculative Waite Ili Allocates As mentioned in previous correspondence, a speculative waste load allocation is a determination by DWQ of your permit limits at a flow MAY-19-99 04:15 PM DIEHL & PHILLIPS 919 467 5327 P.03 May 19, 1999 Page No. 2 higher than your current permitted flow of .75 MGD. I recommend this request bc made for a total flow of .1245 MGD (.495MGD above your current permit) for the reasons explained in item 4 below. I have drafted this request and enclosed a copy for your review. This request must come from the Town rather than myself, so you will have to have it typed on Town stationery, signed and mailed. 3. En ineerin Alter i fives A a 's Re ,o t This report is required for all applications for new or expanding NPDES discharge permits. The report must discuss and evaluate all possible alternatives to the expanded discharge, determine the present worth of each alternative, and rank the alternatives according to their present worth. The Engineering Alternatives Analysis is a detailed and somewhat complex study when the applicant is a private entity considering a new package treatment plant. In the case of a municipality seeking to expand an existing discharge permit, the report may not bc as difficult or detailed. Diehl & Phillips can prepare this Engineering Alternatives Analysis for the Town on a time and material basis, with a not to exceed contract ceiling of $9,000.00. The Analysis would be written for a .459 MGD expansion. For expansion of existing permits, the alternatives analysis does not normally require a detailed report by a soil scientist (to evaluate Iand based treatment systems). If DWQ requires a soil scientist's rcport for your alternatives analysis, this would be an additional expense above the $9,000 ceiling. The Alternatives Analysis report would`require approximately 2 to 3 months to prepare. DWQ will normally take 6-7 months to review it and resolve any questions they have. Once they. decide whether or not to expand the permit, their decision must be advertised. The public will have 30 days to comment, and DWQ will review all comments. If there is substantial public objection, DWQ may hold a public meeting to discuss the permit expansion. It may be 9 to 12 months after submission before the expanded permit is issued, assuming DWQ supported the request and there was no substantial public objection. 4. n Range Grow sideration, The discussion above has been based on a .495 MGD permit expansion because the NC Administrative Code requires an Environmental Assessment (EA) or an Environmental Impact Study (EIS) for expansions of .50 MGD or greater. The time required to prepare an EA or EIS and to have it reviewed and accepted can be a one to three year process. It may MAY-19-99 04:16 PM DIEHL & PHILLIPS 919 467 5327 P.04 May 19, 1999 Page No. 3 involve detailed studies of the receiving team, including surveys of fishes, plant life, fresh water mollusks, and other wildlife. Assuming the Town will ultimately require more than 1.245 MGD of wastewater treatment capacity, you and your Board should start to look at a long range growth plan (if you haven't already). How big do you envision the Town being, and what areas will it serve? Is the current treatment plant location the best one when you consider how the Town wiII grow? I recommend the Town pursue the relatively "quick" .495 MGD permit expansion. At the same time you should begin the long range planning process, which will lead you to knowing how much capacity the sewer plant should ultimately have, and where it should be located. You can then have the EA prepared to support the plant that will ultimately be needed by the Town. Diehl & Phillips has performed long range utility studies for other municipalities and counties, and would be glad to further discuss this with you at your convenience. Please call if you have any questions about any item above, or if you wish to meet. Yours very truly, Diehl & Phillips, P.A. "sae. John F. Phillips, P.E.
