Basin to be overflowing at the Town of Sparta WWTP. On investigation Mr. Shaw found the PLC Control panel to the SBR was completely shut down. All other components of the system were found to be operating properly. After diagnosing / checking the system, Bob disconnected the power at the main breaker and upon reconnecting the power, all systems started functioning properly including the SBR. At approx. 7:43 am all systems were back in service. First Bob called Gary Hudson and got no answer, and then George Smith was notified of the bypass and made aware of the situation. Bob Shaw estimates that approximately 200,000-250,000 gallons of sewage was spilled into the strom drainage system that discharges into the Little River. Bob went and made a visual inspection of the discharge point and found no evidence of waste or any debris from the spill. Also he went downstream on Choate Dairy Road Bridge and found no evidence of debris or material from the spill. It was noticed that minnows were present and swimming at the bridge. No environmental impacts or fish kills were observed. The first corrective measure taken was to clean up debris around the EQ Basin. Bob has also been in touch with Aqua Aerobic Systems personnel in which Bob was informed on how to have our electrician to wire in a backup alarm for a power failure within the SBR system. This is the first time this problem has ever occurred. Electrician will be onsite to install the necessary alarm light to prevent this from happening again. If further information is needed, please feel free to give me a call at 336-372-5015.

Reeder John E. Skvarla, III Governor Director Secretary October 3, 2013 Bryan Edwards, Town Manager Town of Sparta. P.O. Box 99 Sparta, NC 28675 SUBJECT: Compliance Evaluation Inspection (CEI) Town of Sparta WWTP NPDES Permit # NCO026913 Alleghany County Dear Mr. Edwards On October 2, 2013 George Smith performed a Compliance Evaluation Inspection. Mr. Bobby Shaw, ORC, was present for the inspection. The inspection is comprised of an overall evaluation in order to document compliance and noncompliance of: facilities equipment, capability to meet effluent limits, and terms & conditions with the NPDES permit. Permit The permit became effective June 1, 2013 and expired March 31, 2016. A correct copy is kept on file. The Town has no issues with the new permit. Records & Reports The operators log documents the following: rainfall, plant operations, operation & maintenance records, and troubleshooting. The daily worksheet documents process control of the aeration basin, such as: MLSS, Dissolved Oxygen, Temperature, pH, 30-minute Settleable Solids, and Clarifier Blanket Height. These daily logs also document general comments concerning the condition of the plant and record the generator test every Wednesday. The chain -of -custody reports are complete, and they clearly document the sample conditions. The 2012 Annual Performance Report from July 1, 2012 through June 30, 2013 was sent to Raleigh by Mr. Kevin Dowell. Please make sure this report was submitted to the NPDES Unit. 585 Waughtown Street„ North Carolina 27360 Phone: 336-771-50001 Fax: 336-771-4630 Internet: www wwateraualibr.ora An Eaual O000rtunitvlAffirmative Action Emolover CEI 11 October 3, 2013 Page 2 of 3 Facility Site Review The % inch manual barscreen and dual influent 40 h.p. pumps and alarms were all operating properly. The aeration basin had a light brown color and a good earthy odor indicating good treatment. There was a good gentle rolling aeration action with less than 5% light brown foam. The effluent from the clarifier was clear, with a small amount of pin flock over the weirs. No algae present. The skimmer was operating. The flow splitter sends 50% to sequential batch reactor (SBR) and 50% to the conventional treatment plant both are function properly. The lower part of the contact chamber was clear with no foam or floating solids. The chlorine and sulfur dioxide gases are maintained and there are 5 full cylinders in storage. Flow Measurement The flow recording charts are kept on file for the required minimum of three years. Continuous flow measurement at the plant is performed using a 90' V-notch weir with an ultrasonic device mounted before the effluent weir. The flow measuring device was calibrated by Carolina Technical Services on September 4, 2013 Paperwork documentation was maintained in the file. The instantaneous flow was 0.123 MGD at 12:15 pm. Laboratory The municipal lab received field certification (#5233) for Residual Chlorine, pH, and Temperature. The Sension, Hach 156 pH meter is routinely calibrated and documented using a two -point calibration (pH 4 and pH 10), and a midrange check at pH 7. Temperature is recorded with a Sension Hach 156, which is NIST traceable. The Total Residual Chlorine is performed with a Hach DR2500 and the annual 5-point calibration was performed by Pace Analytical on July 25, 2013. The lab measures and documents the field data in an excellent manner. Effluent/Receiving Waters The effluent from the POTW was very slightly cloudy with no solids, no color, or no odor. The visual appearance of the effluent is considered excellent. CEI October 3, 2013 Page 2 of 3 The unnamed tributary to Little River, Class C waters showed no adverse impacts. Operations & Maintenance The following Town personnel operate the facility: Bobby Shaw ORC, Grade III; Eddie Hall, Grade II; Andy Blevins, Maintenance. Please insure that Andy Blevins obtains a Grade II if you intend for him to act as a Back-up ORC. The MLSS is approximately 2599 mg/L and the settleability is 17%, which is low because Mr. Shaw just wasted some solids into the digester. Self -Monitoring Program A review of the monthly self -monitoring reports from October 2011 through July 2013 revealed no limit violations. The Town currently performs influent composite sampling with an Isco sampler. A sample aliquot of 50 ml is collected every 15 minutes. The Town currently performs effluent composite sampling with an Isco sampler. A 100 mL sample is collected every 2,400 gallons. This complies with the effluent flow proportion sample requirement. Sludge Disposal The digester is currently maintained at approximately 50% capacity to waste solids. The compliance evaluation inspection is satisfactory. The quality of the effluent is considered to be excellent at the time of the inspection, and the plant personnel are considered to perform their jobs in an excellent manner.

Skvarla, III Governor Director Secretary April 26, 2013 Mr. Bryan Edwards, Town Manager Town of Sparta PO Box 99 Sparta, NC 28675 Subject: NPDES Permit Renewal Permit NCO026913 Alleghany County Class III Facility Dear Mr. Edwards: Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES permit. This permit is issued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S. Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). We received your comment pertaining to the proposed mercury limit. A permitting strategy was developed to implement the Statewide Mercury TMDL developed by Division and approved by the USEPA in 2012. The permitting strategy is designed to maintain the mercury load below the assigned wasteload allocation and to avoid mercury hotspots. The Division developed a technology based effluent limit (TBEL) of 47 ng/l based on pollutant removal technology. At the time of permit renewal all facilities are evaluated for mercury limits. A reasonable potential analysis is performed to evaluate potential to exceed the water quality based limit (WQBEL) or the TBEL, whichever is more stringent. Your data shows two detections above the TBEL. As such the permit includes a limit of 47 ng/1 implemented as an annual average of quarterly samples. This limit will become effective on January 1, 2015. If any parts, measurement frequencies or sampling requirements contained in this permit are unacceptable to you, you have the right to an adjudicatory hearing upon written request within thirty (30) days following receipt of this letter. This request must be in the form of a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Location: 512 N.

Box 99 Sparta, NC 28675 SUBJECT: Compliance Evaluation Inspection (CEI) Town of Sparta WWTP NPDES Permit # NCO026913 Alleghany County Dear Mr. Edwards Dee Freeman Secretary On October 7, 2011 George Smith performed a Compliance Evaluation Inspection. Mr. Bobby Shaw, ORC, and Mr. Andy Blevins, Back-up ORC were present for the inspection. The inspection is comprised of an overall evaluation in order to document compliance and noncompliance of: facilities equipment, capability to meet effluent limits, and terms & conditions with the NPDES permit. Permit The permit became effective March 1, 2007 and expired March 31, 2011. A correct copy is kept on file. A permit renewal application was submitted. The POTW is rated as a Grade III facility because it has a permitted flow of greater than 0.5 through 2.5 MGD. The sampling for a Grade III is 3 times per week. Records & Reports The operators log documents the following: weather, plant operations, operation & maintenance records, and troubleshooting. The daily worksheet documents process control of the aeration basin, such as: MLSS, Dissolved Oxygen, Temperature, pH, 30-minute Settleable Solids, and Clarifier Blanket Height. These daily logs also document general comments concerning the condition of the plant and record the generator test every Wednesday. The chain -of -custody reports are complete, and they clearly document the sample conditions. The Annual Performance Report from July 1, 2010 through June 30, 2011 was sent to Raleigh and received in this office.

The aeration basin had a brown color and a good earthy odor indicating good treatment. There was a good gentle rolling action and the dissolved oxygen runs between 3 — 4 mg/L. The effluent from the clarifier was clear, with a small amount of pin flock over the weirs. No algae present. The skimmer was operating. The flow splitter, equalization tank and sequential batch reactor (SBR) are function properly. The upper section of the chlorine contact chamber had some foam and floating solids. The lower part of the contact chamber was clear with no foam or floating solids. Flow Measurement The flow recording charts are kept on file for the required minimum of three years. Continuous flow measurement at the plant is performed using a 90' V-notch weir with an ultrasonic device mounted before the effluent weir. The flow measuring device was calibrated by Carolina Technical Services on September 28, 2011 Paperwork documentation was maintained in the file. Laboratory The municipal lab received field certification (#5233) for Residual Chlorine, pH, and Temperature. The Sension, Hach 156 pH meter is routinely calibrated and documented using a two -point calibration (pH 4 and pH 10), and a midrange check at pH 7. Temperature is recorded with a Sension Hach 156, which is NIST traceable. The lab measures and documents the field data in an excellent manner. Effluent/Receiving The effluent from the POTW was very slightly cloudy with no solids, no color, or no odor. The visual appearance of the effluent is considered very good. The unnamed tributary to Little Buffalo Creek, Class C-Trout + waters showed no adverse impacts. VCE October 17, 2011 Page 3 of 3 Operations & Maintenance The following Town personnel operate the facility: Bobby Shaw ORC, Grade III; Andy Blevins, Back-up ORC. Currently, Tim Church, Grade IV and Eddie Hall, Grade II are listed as back-up operators. It appear that Tim Church is the designated Back-up ORC. Please insure that Andy Blevins obtains a Grade II if you intend for him to be a Back-up ORC. The clarifier is maintained with a 7 -foot blanket. Self -Monitoring Prog am A review of the monthly self -monitoring reports from October 2010 through July 2011 revealed no monitoring or limit violations. The Town currently performs influent composite sampling with an Isco sampler. A sample aliquot of 50 ml is collected every 15 minutes. The Town currently performs effluent composite sampling with an Isco sampler. A sample aliquot of 50 ml is collected every 2,400 gallons. This complies with the flow proportion sample requirement. Sludge Disposal The digesters are maintained at approximately 30% capacity to waste solids. This is considered an excellent operations strategy, especially through the winter months. The inspection is satisfactory. The quality of the effluent is considered to be very good and the plant personnel are considered to perform their jobs in an excellent manner.

Sometime during the week ending on the 30th of JUly we experienced an electrical storm here in Town. During this event, we had an electrical surcharge that ran in on our Flow Meter and also took out the "electronic board" of the Regal Smart Valve of our Chlorine fed system. Technicians were here on August 8,2011 and have started the process of getting us back online. We are told that it will be approximately 2 weeks to get everything back up and going. Until that time, please be advised that there will be no flow readings and that chlorine and sulfur dioxide will have to be manually fed until system is repaired. We will keep you informed as to the progress of this situation. If you have any questions or concerns, please contact Mr. Bobby Shaw (ORC ) at 336-372-5015.

This type of inspection consists of two basic parts: an in office file review and an on -site inspection of the treatment facility. The attached EPA inspection form notes the eight (8) areas that were evaluated for this inspection. The findings and observations are outlined below: I. Permit The NPDES permit was reissued with an effective date of March 1, 2007. This permit is due to expire on March 31, 2011. The town's application for renewal should have been mailed in 180 days prior to the expiration date or September 30, 2010. II. Self -Monitoring Program The monthly self -monitoring reports (DMR's) were reviewed for the period November 2009 through October 2010. The facility was found to be in complete compliance with all final NPDES effluent limits. In addition, all monitoring was performed and recorded per the frequencies specified in the permit. III. Flow Measurement The permit requires continuous flow recording and is measured by an ISCO 4250 meter. Carolina Technical Services last calibrated the meter on June 29, 2010. IV. Sludge Handlina and Disposal Solids are land applied by Synagro under non -discharge permit # W00006242. V.

However, a receiving WWTP may have to get their Attachment A amended in their permit for an additional source. Otherwise, we would have to issue them some kind of a letter of approval if Sherri agrees and we get the OK from Raleigh. If I recall we have something similar to this before. The landfill would be the easiest scenario. They need to keep records for the land fill to turn in with their annual report so we know what happened to the sludge.

Box 99 Sparta, North Carolina 28675 Subject: Inactivation of Pretreatment Program Town of Sparta (NC0026913) Alleghany County Dear Mr. Edwards: The Pretreatment, Emergency Response and Collection Systems (PERCS) Unit of the Division of Water Quality has reviewed the Town of Sparta's request to change the status of the approved Pretreatment Program from "Active" to "Inactive". This request was received by the Division on January 4, 2011. As the Town currently has no Significant Industrial Users (SIUs), the Town's request to inactivate the Pretreatment Program is approved. If an SIU proposes to discharge wastewater to your WWTP, you must notify the Division, reactivate your Pretreatment Program, and update the major Program elements as necessary. Please see Part IV, Section B, 4, of your NPDES permit. Since you will not be accepting wastewater from any SIUs while your Pretreatment Program is Inactive, and the Town's NPDES permitted flow is less than I MGD, it is PERCS' understanding that the facility can now be reclassified as a Minor facility. Please contact Charles Weaver of the NPDES staff at 919-807-6391 (charles.weaver(a)nedenr.gov) to discuss this reclassification. Thank you for your continued cooperation: with the Pretreatment Program. If you have any questions or comments, please contact Dana Folley at (919) 807-6311 (dana.folleyamcdenr.Qov) or Deborah Gore, Unit Supervisor at 807-6383 [email: deborah.goreamederingov].

The Sparta WWTP should be classified as a Major facility, per the definition for Major/Minor facilities found in the General Statute: § 143-215.31). Fee schedule for water quality permits. (a) Annual fees for discharge and nondischarge permits under G.S. 143-215.1. — (1) Major Individual NPDES Permits. — The annual fee for an individual permit for a point source discharge of 1,000,000 or more gallons per day, a publicly owned treatment works (POTW) that administers a POTW pretreatment program, as defined in 40 Code of Federal Regulations § 403.3 (1 July 1996 Edition), or an industrial waste treatment works that has a high toxic pollutant potential is three thousand four hundred forty dollars ($3,440). Beginning in 2011, you will be billed the permit fee for a Major NPDES permit for the subject facility.

In accordance with your request, Certificate of Coverage Nu.- . _..: NCG030514 is rescinded effective immediately. Operating a treatment facility, discharging wastewater or discharging specific types of stormwater to waters of the State without valid coverage under an NPDES permit will subject the responsible party to a civil penalty of up to $25,000 per day. It is the intention of DWQ that enforcement proceedings will occur for ;persons that have voluntarily relinquished permit coverage when, in fact, continuing permit coverage was necessary. If, in retrospect, you feel the site still requires permit coverage, you should notify this office immediately. Furthermore, if in the future you wish to again discharge to the State's surface waters, you. must first apply for and receive a new NPDES permit. If the facility is in the process of being sold, you will be performing a public service if you would inform the new or prospective owners of their potential need for NPDES permit coverage. If you r -ve questions about this matter, please contact Brian Lowther at (919) 807-6368, or the Water Qu,-lity staff in our Winston-Salem Regional Office at (336) 771-5000. Sincerely, for Coleen H.

The existing WWTP consists of: bar screen, influent pump station, and flow splitter. The flow is then split equally between the equalization basin and SBR w/floating decanter, and the aeration basin w/o EQ) and secondary clarifier. Flow then recombines prior to gas chlorination unit, contact chamber, sulfur dioxide gas dechlorination unit and aerated sludge holding. Mike Mickey, from the Winston-Salem Regional office; conducted a site visit on 10-11-05 and found the facility in compliance at the time of inspection. The WSRO recommends permit renewal and states the facility is consistently in compliance. The facility has a 160,000-gallon digestor where sludge is wasted on a daily basis and is held for stabilization for a period of twelve months. It is then applied to farmland in conjunction with land application permit #WQ0006242 by Synagro Corporation. PRETREATMENT The facility has an active modified pretreatment program with a short term monitoring plan and no permitted SIU's since 2002 but wants to maintain their program as active. Metals values reported by pretreatment STMP and DMR submittals shows no values over permit limits. RECEIVING STREAM This facility discharges to Little River in the New River Basin, classified C waters in Subbasin 05-07-03. The Little River, from source to the New River (32.8 miles), is Supporting in the aquatic life category. The Little River is Not Rated for recreational use due to elevated fecal coliform bacteria. Potential sources of elevated bacteria levels include failing septic systems, straight pipes, and nonpoint source runoff from pasturelands. DWQ will continue to monitor water quality in Little River and work with local agencies to identify possible sources of the elevated fecal bacteria levels.

INSTREAM MONITORING: Not required in the existing permit, will not be required in permit renewal. Toxicant Analysis: A reasonable potential analysis (RPA) was not conducted because all values were below detect for the toxicants currently monitored in the NPDES permit and the Pretreatment STMP. The data evaluated was reported between from July 2003 - July 2006. The DMR reported values below detection for a three-year period. Monitoring will continue through the NPDES permit and the STMP. Aquatic Toxicity Testing Testing results from (2002-2006) reflects passing the test with no failures. Proposed Changes: • Addition of Weekly Average NH3 limits of 27.9 mg/ L for Summer Months. • Addition of pH limits on effluent page. • Addition of Pollutant Analysis on 0.60 Effluent Page. • Deletion of Cadmium, Selenium and Mercury limits. • Change in monitoring frequency for Cadmium, Selenium and Mercury from weekly to 2/month.
