Depot Street, Suite 200 Mocksville, NC 27028 SUBJECT: Compliance Evaluation Inspection Sparks Road WTP Discharge NPDES Permit No. NCO084212 Davie County Dear Mr. Lambert: PAT MCCRORY Govemor DONALD R. VAN DER VAART Secretary S. JAY ZIMMERMAN Director On December 15, 2015, Mike Mickey of this office met with Matt Seats and Michael Weir, ORC, to perform a Compliance Evaluation Inspection of the NPDES wastewater discharge from the Sparks Road Water Treatment Plant (WTP). The inspection findings are detailed below and an inspection checklist is attached. I. Permit The NPDES permit expires next on May 31, 2019. Permit condition A.(3) required the submittal of electronic discharge monitoring reports (eDMRs) on or before April 1, 2015. The first electronic DMR for the Sparks Road facility was submitted for February 2015, well ahead of the above deadline. H. Self -Monitoring Proeram The inspection reviewed DMRs that were submitted for the period January 2015 through November 2015. The Sparks Road WTP was found to be compliant with all effluent limits during this period (see data summary attached), except for a daily maximum and monthly average TSS violation that occurred in October. These violations will be addressed in subsequent correspondence from this office. With regards to the permit monitoring requirements, it was noted that all sampling was being performed per the frequencies specified in the permit. III. Flow Measurement The NPDES permit requires continuous flow recording and an annual calibration of the flow measuring device. The effluent flow values reported on the DMRs are measured using an ultrasonic meter with parshall flume. The meter was last calibrated by Fortech on August 17, 2015. IV. Sludge Handling and Disposal Solids collected in the settling lagoons are land applied under non -discharge permit No. WQ0028806. The residuals were last removed by EMA Resources in 2010. Accumulated solids may be removed from one lagoon in the spring of 2016. V. Operations and Maintenance The facility was competently operated and maintained. The only concern noted during the inspection involved the erosion along the banks of the settling lagoons. The lack of vegetation was resulting in high TSS and turbidity levels in the lagoon effluent after significant rainfall events. It is hoped that the banks can be lined with matting and gravel in 2016.

Facility Site Review The treatment system components for the filter backwash and clarifier wastewater consist of the following: two 785,000 gallon settling lagoons operated in parallel, tablet dechlorinator and flow meter. VH. Records/Reports A comparison of the November 2015 DMR with the operator's field records for flow, pH and total residual chlorine along with the laboratory results from Statesville Analytical showed that all data was transcribed onto the DMR correctly. VM. Effluent/Receiving Waters The system discharges into a ditch leading to a tributary of the Yadkin River, class "WS-IV" waters in the Yadkin -Pee Dee River Basin. The effluent was clear on the day of inspection. Our office appreciates your efforts to comply with the NPDES permit. Should you have any questions concerning this report, please contact Mike Mickey or me at (336) 776-9800. Sincerely, Sherri V.

For the review period January 2015 through November 2015 the Sparks Road WTP was found to be compliant with all effluent limits and monitoring requirements, except for violation of the TSS daily maximum and monthly average limit in October. These exceedances were due to erosion around the settling lagoons that after heavy rainfall events. Plans are in the works to install matting and gravel to remedy the situation.

There are 2 permits, NCO028472 (Davie County Water System/Cooleemee WWTP) and NCO084212 (Davie County Public Utilities/Sparks Road WTP, and appears they should be under the same owner. NCO084212 has already registered and now they want to register NC0028472. Both permits should have registered when NCO084212 was registered but failed to do so due to having different owner names in BIMS, Davie County Water System and Davie County Public Utilities. The owner needs to reflect the same name for both in BIMS. Once this is corrected, we can manually add the other permit to eDMR. Please take a look at this and update one of the permits to reflect the correct owner name. Thanks .... Tom Thomas F.

(18 U.S.C. Section 1001 provides a punishment by a fine of not more than $25,000 or imprisonment not more than 5 years, or both, for a similar offense.) Page 4 of 4 Version 5/2012 Davie County Public Utilities Sparks Road Water Treatment Plant Sludge Handling Plan The Sparks Road WTP has two parallel 785,000-gallon filter backwash lagoons. The lagoons Provide long-term storage of sludge developed during clarifier flushing and filter backwash operation sl atdge is added to the lagoons the s. As chemical solids are settled by gravity. Tla.e supernatant is discharged through the overflow -supernatant pipe to a m, im made ditch that flows to an unnamed tributary of the Yadkin River. Sludge depth is monitored in each lagoon and lagoons are designed to laiiit up to 10 years at the expected plant sludge disposal rate before solids ha+re to be removed. Once lagoons are classified as full, sludge in the lal loons is dredged and land applied on neighboring farm fields. prior to dri 4ging a land application permit is acquired and the sludge is analyzed to as:iure it is safe to apply. The sludge removal is contracted out to a spii,cialized private company to assure that all state and federal laws would be followed though out the sludge removal process. In summary the sludge handling at this facility happens only once evEr 10 years and is contracted out for land application.

Reeder John E. Skvarla, III Governor Director Secretary January 31, 2014 Mr. Johnny Lambert Public Works Director County of Davie 298 E. Depot Street, Suite 200 Mocksville, NC 27028 SUBJECT: Compliance Evaluation Inspection Sparks Road WTP Discharge NPDES Permit No. NCO084212 Davie County Dear Mr. Lambert: On January 30, 2014, Mike Mickey of this office met with Michael Weir, ORC, to perform a Compliance Evaluation Inspection of the NPDES wastewater discharge from the Sparks Road Water Treatment Plant (WTP). The treatment system was found tobe in consistent compliance with the effluent limits and monitoring requirements of the NPDES permit. The inspection findings are detailed below and an inspection checklist is attached for your records. I. Permit The NPDES permit expires on May 31, 2014. Per Part II.B(10) of the permit, a renewal request should have been submitted to the Division at least 180 days prior to expiration. To date, a renewal request has not been received. The application should be submitted to Raleigh on or before February 14, 2014. H. Self -Monitoring Program The monthly self -monitoring reports (DMRs) were reviewed for the period January 2013 through December 2013. The facility was found to be compliant with all permit effluent limits (see data summary attached), except for one daily maximum pH violation that occurred in May 2013. This violation was previously addressed in a Notice of Deficiency letter from this office. In regards to the permit monitoring requirements, it was noted that all sampling was being performed per the frequencies specified in the permit. The review did note that the effluent failed the chronic toxicity test conducted in February 2013. It is our understanding that excessive chlorine was the cause of the test failure. At present, the toxicity requirement in the permit is monitoring only with no effluent limitation. III. Flow Measurement The NPDES permit requires continuous flow recording and annual calibration of the flow measuring device. The daily effluent flow values reported on the DMRs are measured using an ultrasonic meter with parshall flume. The meter was calibrated by Fortech on June 27, 2013.

The residuals were last removed by EMA Resources in 2005 and 2010. V. Operations and Maintenance The facility was competently operated and maintained. No problems or concerns were noted. VI. Facility Site Review The treatment components for the filter backwash and clarifier wastewater consist of the following: two 785,000 gallon settling lagoons operated in parallel, two tablet dechlorinator tubes and an ultrasonic flow meter with parshall flume. VH. Records/Reports A comparison of the November and December DMRs with the laboratory data from Statesville Analytical showed that all data was transcribed onto the DMRs correctly, except for the December 17t` samples that were accidently entered on the line for December 16t'. It was noted that the units of measurement (mg/L) for aluminum, manganese, fluoride, zinc, copper, total nitrogen and total phosphorus were not being listed on the DMR. Please include the unit of measurement for these parameters on the form. VHI. EftluentlReceiving Waters The system discharges into a tributary of the Yadkin River, class "WS-IV" waters in the Yadkin -Pee Dee River Basin. The effluent was clear on the day of inspection. Our office appreciates your efforts to comply with the NPDES permit. Should you have any questions concerning this report, please contact Mike Mickey or me at (336) 771-5000. Sincerely, /0'%.

Permit: NCO084212 Inspection Date: 01/30/2014 Owner - Facility: Sparks Road WTP Inspection Type: Compliance Evaluation Permit (If the present permit expires in 6 months or less). Has the permittee submitted a new application? Is the facility as described in the permit? # Are there any special conditions for the permit? Is access to the plant site restricted to the general public? Is the inspector granted access to all areas for inspection? Comment: A review of the monthly self -monitoring reports for the period January 2013 through December 2013 found that all monitoring was performed per the frequencies specified in the permit. In addition, the Sparks Road WTP was found to be compliant with the effluent limits of the NPDES permit, except for one daily maximum pH exceedence that occurred on May 21, 2013. (the high pH was caused by excessive algae in the lagoon. Treatment with copper sulfate cured the problem). The permit expires on May 31, 2014. Per Part II.B(10) of the permit, a renewal request should have been submitted to the Division at least 180 days prior to expiration, or before November 30, 2013. To date, a renewal request has yet to be submitted by Davie County. It is our understanding that John Grey is currently working on the paperwork.

Page # 5 Mickey, Mike From: Mickey, Mike Sent: Thursday, January 30, 2014 4:17 PM To: Berry, Stephen Subject: Sparks Road WTP - NC0084212 / WQ0028806 Stephen — Visited the WTP today and met with Mike Weir/ORC. They last applied residuals in 2005 (155 dry tons from one settling lagoon) and again in 2010 (270 dry tons from both lagoons). Roy Whitaker with EMA uses a boat and sludge judge to determine when solids need to be removed. No plans to pump in 2014 as storage in the two settling lagoons is still adequate. The facility has a single raw water storage lagoon. They pump to this lagoon from the intake structure at the Yadkin River. They only have to pump from the river a few days a week in order to fill the lagoon. They try to pump at times when the river is clearer, reducing the generation of excessive solids to the settling lagoons when the filters are backwashed.

Thought I should let you know that this summer the legislature amended the law so that annual reports are now only required from municipal/domestic facilities with an average annual flow greater that 200,000 gpd. Since the WTP does not treat municipal or domestic wastewater, you should be done with annual reports. See cite below. Mike. § 143-215.1C.

(a) Report to Wastewater System Customers. — The owner or operator of any wastewater collection or treatment works, the operation of which is primarily to collect or treat municipal or domestic wastewater and for which a permit is issued under this Part and having an average annual flow greater than 200,000 gallons per day, shall provide to the users or customers of the collection system or treatment works and to the Department an annual report that summarizes the performance of the collection system or treatment works and the extent to which the collection system or treatment works has violated the permit or federal or State laws, regulations, or rules related to the protection of water quality.

Sullins Director March 26, 2010 SUBJECT: Compliance Evaluation Inspection Davie County - Spark Road WFP NPDES Permit No. NCO084212 Davie County Dear Ms. Dirks: Dee Freeman Secretary On March 23, 2010, Mike Mickey of this office met with Michael Weir, ORC,' to perform a Compliance Evaluation Inspection on the NPDES wastewater discharge from the Sparks Road water treatment plant. 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 seven (7) areas that were evaluated for this inspection. The findings and observations are outlined below: I. Permit The NPDES permit was reissued on December 1, 2009. Footnote "1" on the Effluent Limitations page of the new permit states that continuous flow monitoring becomes effective on March 1, 2011. It is our understanding that plans are already underway to install a flow meter at the start of the next fiscal year. II. Self -Monitoring_ Program Monthly self -monitoring reports were reviewed for the period January 2009 through December 2009. The facility was found to be in complete compliance with all effluent limits for this time period (see data summary attached). In addition, all monitoring was performed per the frequencies specified in the permit. Field parameter certification was recently renewed for on -site testing of total residual chlorine. Approval for on -site pH testing is pending. III. Flow Measurement Flow from the settling lagoons is currently estimated using the v-notch weir on the end of the discharge pipe.

Facility Site Review Wastewater generated from clarifier and filter backwash is routed to two 785,000 gallon settling lagoons in parallel. The supernatant overflow is dechlorinated prior to discharge. The facility plans to remove solids from one settling lagoon this year for land application under permit number WQ0028806. V. Operations & Maintenance The operation and maintenance of the facility appeared to be excellent. No concerns were noted. VI. Records/Reports A review of the facility files showed that all records are being maintained according to the permit and that all monitoring was performed per the frequencies listed in the NPDES permit. In addition, the 2009 annual report was submitted as required. VII. Effluent/Receiving Waters The system discharges into an unnamed tributary to the Yadkin River, Class "WS-IV" waters. The effluent was crystal clear on the day of the inspection. Should you have any questions concerning this report, please contact Mike Mickey or me at (336) 771-5000. Sincerely, Steve W.

NPDES has since updated the Water Treatment Plant permitting strategy to remove flow limits on all WTPs (flow monitoring requirement will remain). Unlike WWTPs, flow data was not critical for treatment design purposes, and NPDES still has use of DMR flow data to conduct RPA analysis. Also, the WTP strategy still precludes any new or expanding RO/IE plants to freshwater streams. Given the number of WTPs with existing flow limits (approx 115) and potential cost for public notice to remove limit, NPDES is proposing to remove existing WTP effluent flow limits upon permit renewal. It is recommended that Regions use BPJ for any flow violations associated with water treatment plants, until the limits are eventually removed at permit renewal. Let me know if you have any questions.

Mocksville, NC 27028 May 12, 2009 Mr. Bob Sledge NCDENR Division of Water Quality Point Source Branch 1617 Mail Service Center Raleigh, NC 27699-1617 Subject: Draft NPDES Permit Comments NPDES Permit NC0084212 Davie County — Sparks Road WTP Dear Mr. Sledge: Upon reviewing our draft NPDES permit NC0084212 we have some concerns regarding the changes to our monitoring requirements. We acknowledge the changes but are requesting some of the limits and monitoring requirements be adjusted to better suit our facility. Our first concern pertains to the monthly average flow limit of 0.023 MGD for our facility. We believe that this limit is a typo and should actually be 0.230 MGD. Our previous permit allowed us to take weekly instantaneous flow readings from our 45-degree v-notch weir. With the monitoring requirement changing to continuous we will have to upgrade our facility with a more accurate flow -measuring device that can communicate to our scada system for data collection. After reviewing historical plant data we have on the amount of plant discharge to our lagoons and with the installation of a more accurate flow -measuring device we feel that during some months we will not be able to meet the 0.230 MGD monthly average flow limit. With these concerns we are asking that this monthly average flow limit be increased to 0.360 MGD. I have attached a simple excel spreadsheet that shows our monthly data taken from the v-notch weir versus the data we have in the plant pertaining to backwash sent to the lagoons. This data does not take into account filter wasting that may take place during plant operations. The highlighted data indicates months that we would not meet our proposed now limit requirements of .230 average mgd. Another concern is with the increased amount of effluent characteristics being sampled and monitoring frequencies. We would like to see footnote 4 be added to Aluminum, Total Zinc, Total Copper, Total Iron, and Whole Effluent Toxicity. After sufficient data has been collected we would like the opportunity to request a review of reasonable potential for monitoring and effluent limitations as stated in footnote 4. Davie County Public Utilities strives to protect our watershed and we will continue to do everything in our power to meet our NPDES permit requirements. Best regards, Michael C. Weir Sparks Rd.

Monitoring should be performed in conjunction with toxicity testing. 6. See Condition A. (2.) for toxicity testing requirements. Toxicity sampling should coincide with sampling for parameters covered by footnote 5. There shall be no floating solids or foam in other than trace amounts. Permit NCO084212 A. (2.) CHRONIC TOXICITY MONITORING (QUARTERLY) The permittee shall conduct uq arterly chronic toxicity tests using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions. The effluent concentration defined as treatment two in the procedure document is 90 %. The testing shall be performed as a Ceriodaphnia dubia 7day pass/fail test. The tests will be performed during the months of February, May, August and November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally, DWQ Form AT-1(original) is to be sent to the following address: Attention: NC DENR / DWQ /Environmental Sciences Section 1621 Mail Service Center Raleigh, N.C. 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. 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 Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin immediately. Upon submission of a valid test, 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. If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms submitted. 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. Mickey, Mike From: Mickey, Mike Sent: Monday, May 11, 2009 11:19 AM To: Sledge, Bob Cc: 'Tedder, Steve' Subject: Draft Permit - Davie Co. WTP - NC0084212 Bob - Below are my comments on the above draft permit for the Sparks Road WTP: 1) The monthly average flow limit of 0.023 MGD is too low. Is this a decimal error? The cover letter states that the limit is based on the highest monthly average flow reported over the last three years. I pulled just the 2008 monitoring reports from our files and the highest month was 0.177 MGD in October 2008. 1 would suggest that the limit be set higher than any value they have reported to date. With anticipated growth in the county the WTP output will surely increase causing higher backwash flows than previously reported. Perhaps the NPDES flow limit could be based on maximum backwash flow at maximum WTP output so we don't create a noncompliance issue. 2) Suggest a grace period of 18 months instead of 12 months to have flow meter installed. Spoke with Mike Weir, ORC, on Friday and he indicated that they are working to find funds for an open channel flow meter with sonar attached to their SCADA system. 3) Recommend that footnote (4) also apply to Whole Effluent Toxicity testing. If the effluent does not exhibit toxicity then monitoring could be discontinued. Thanks, Mike. Please note new E-mail address: Mike.

The requirement for continuous flow monitoring will become effective 12 months following the effective date of the permit. 2. The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina certified laboratory (including field certified), even if these values fall below 50 n/L. 3. The pH shall not be less than 6.0 standard units, nor greater than 9.0 standard units. 4. After sufficient data have been collected (8 —12 data points over at least one year), the Permittee may request a review of reasonable potential for monitoring and effluent limitations. 5. Monitoring should be performed in conjunction with toxicity testing. 6. See Condition A. (2.) for toxicity testing requirements. Toxicity sampling should coincide with sampling for parameters covered by footnote 5. There shall be no floating solids or foam in other than trace amounts. Permit NC0084212 A. (2.) CHRONIC TOXICITY MONITORING (QUARTERLY) The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised February 1998, or subsequent versions. The effluent concentration defined as treatment two in the procedure document is 90 %. The testing shall be performed as a Ceriodaphnia dubia 7day pass/fail test. The tests will be performed during the months of February, May, August and November. Effluent sampling for this testing shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the month in which it was performed, using the parameter code TGP3B. Additionally, DWQ Form AT-1 (original) is to be sent to the following address: Attention: NC DENR / DWQ / Environmental Sciences Section 1621 Mail Service Center Raleigh, N.C. 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Environmental Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. 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 Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, then monthly monitoring will begin immediately. Upon submission of a valid test, 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. If the Permittee monitors any pollutant more frequently then required by this permit, the results of such monitoring shall be included in the calculation & reporting of the data submitted on the DMR & all AT Forms submitted. 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.
