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. The changes between this permit and the previous permit include the following: • The coordinates for the Outfall 001 were adjusted to the following: Latitude: 34° 51' 38" Longitude: 76° 53' 38" • The flow limit is removed. • In accordance with the NPDES Permitting Strategy for WTP's, facilities discharging greater than 50,000 gpd are required to install a continuous recorder to monitor wastewater discharge flows. As a result, continuous flow monitoring has been added to your permit. The Town will have 18 months from the effective date of this permit to install a continuous flow meter. Until then instantaneous measurements can be taken with the duration of discharge to be noted in log books and a total daily discharge reported on the DMR. • Temperature, Total Lead and Total Quarterly Flow monitoring is no longer required. • Total Suspended Solids (TSS) for upstream and downstream is no longer required. • Turbidity monitoring is added with monthly monitoring. • Since Total Suspended Solids (TSS), Total Residual Chlorine (TRC) and pH are limited monitoring is twice (2) per month. • Composite sampling is now required for Total Suspend Solids (TSS), Total Dissolved Solids (TDS), Salinity, Conductivity, Total Nitrogen (TN), Total Kjeldahl Nitrogen (TKN), Nitrate and Nitrite Nitrogen, and Total Phosphorus. • Upstream and downstream sample is now required for Dissolved Oxygen (DO), pH, Salinity and Conductivity sampling. If no stream flow is available for sampling, please indicate "no stream flow" on your DMR. Salinity and Conductivity sampling is grab. 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 Phone: 919-807-63001 Internet: www.ncwaterquality.org An Equal Opportunity 1 Affirmative Action Employer — Made in part by recycled paper Mr. Freeman July 21, 2014 Page 2 of 2 Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency (EPA).

The Town will have until March 1, 2016, approximately 18 months from the effective date of this permit, to install a continuous flow meter. Until then instantaneous measurements can be taken with the duration of discharge to be noted in log books and a total daily discharge reported on the DMR. 4. The Division shall consider TRC effluent values reported below 50 µg/L to be compliant with the permit. However, the Permittee shall continue to record and submit all values reported by a North Carolina -certified laboratory method (including field certified), even if these values fall below 50µg/L. 5. For a given wastewater sample, TN = TKN + NO3-N + NO2-N, where TN is Total Nitrogen, TKN is Total Kjeldahl Nitrogen, and NO3-N and NO2-N are Nitrate and Nitrite Nitrogen, respectively. 6. Whole Effluent Toxicity (WET) testing - testing of Mysidopsis bahia shall be performed as 24-day pass/fail test at 90% effluent'concentration, during January, April, July and October [See A. (2.)]. 7. If no stream flow is available to sample, indicate "no stream flow" on DMR. Samples shall be taken at the outfall but prior to mixing with the receiving waters. There shall be no discharge of floating solids or foam in other than trace amounts. Page 4 of 7 NPDES Permit NCO078131 A. (2.) ACUTE TOXICITY PASS/FAIL MONITORING (QUARTERLY) The permittee shall conduct acute toxicity tests on a quarterly -basis using protocols defined in the North Carolina Procedure Document entitled "Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent Concentration" (Revised -December 2010 or subsequent versions). The monitoring shall be performed as a Mysid Shrimp (Mysidopsis bahia) 24 hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document). The tests will be performed during the months of January, April, July and October. These months signify the first month of each three month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and 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 TGE3E. Additionally, DWR Form AT-2 (original) is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, North Carolina 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Water 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 pernttee 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 Water 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 either these monitoring requirements or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re- opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival 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. Page 5 of 7 NPDES Permit NCO078131 A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and specify that, if a state does not establish a system to receive such submittals, then permittees must submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates that these regulations will be adopted and is beginning implementation in late 2013. NOTE: This special condition supplements or supersedes the following sections within Part H of this permit (Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2.) • Section D. (6.) • Section E. (5.) Reporting Records Retention Monitoring Reports 1. Reporting (Supersedes Section D. (2.) and Section E. (5.) (a)1 Beginning no later than 270 days from the effective date of this permit, the permittee shall begin reporting discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR) internet application. Monitoring results obtained during the previous month(s) shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross -Media Electronic Reporting Regulation (CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DENR / DWR / Information Processing Unit ATTENTION: Central Files / eDMR 1617 Mail Service Center Raleigh, North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1. 1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. Requests for temporary waivers from the NPDES electronic reporting requirements must be submitted in writing to the Division for written approval at least sixty (60) days prior to the date the facility would be required under this permit to begin using eDMR. Temporary waivers shall be valid for twelve (12) months and shall thereupon expire. At such time, DMRs shall be submitted electronically to the Division unless the permittee re -applies for and is granted a new temporary waiver by the Division. Page 6 of 7 NPDES Permit NCO078131 Information on eDMR and application for a temporary waiver from the NPDES electronic reporting requirements is found on the following web page: http://portal.ncdenr.or web/wq/admin/bog/ipu/edmr Regardless of the submission method, the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. 2. Signatory Requirements [Supplements Section B. (11.) (b) and supersedes Section B. (11.) (d)l All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B.

Because the waste flow is >0.050 MGD, continuous flow monitoring is required. The facility consists of the following water and wastewater treatment units: • water supply well system • aeration basins • oxidation • six (6) greensand/anthracite filters • four (4) ion -exchange water -softeners • a 1,000,000 gallon storage tank • settling / holding basin • catch basin with dechlorination equipment • chemical usage consists of o bleach (sodium hypochlorite) o zinc orthophosphate o sodium permanganate o ammonium sulfate o sodium sulfite (dechlorination tablets) Monthly average FLOW ,MGD) — Last 36 months Apr2011-Mar2014: [Ave 0.120 MGD; Maximum, Monthly average flow = 0.271 MGD] Fact Shect Rene%%al 2014 -- NPDES Permit NCO078I i 1 Pane 1 Toxici — With a Tidal discharge that is not modeled, this permit requires Acute Whole Effluent Toxicity (WET) testing using Mysidopsis bahia to be performed as 24-day pass/fail test at 90% effluent concentration, during January, April, July and October [TGE3E]. This facility has passed toxicity tests over 4 %2 years (last 2 years apply to review). Renewal Summary — This permit reflects discharge at Outfall 001. DWR updated the facility description and Map; added parameter codes to Section A. (1.); added Electronic Reporting - Discharge Monitoring Reports page [Section A. (3.)]; added monthly continuous flow monitoring and Turbidity monitoring; removed flow limit, temperature, total Lead, and Total Quarterly Flow monitoring; removed upstream and downstream monitoring for Total Suspended Solids (TSS); added upstream and downstream monitoring for Dissolved Oxygen (DO) and pH; added composite sampling for Total Suspend Solids (TSS), Total Dissolved Solids (TDS), Total Nitrogen (TN), Total Kjeldahl Nitrogen (TKN), Nitrate and Nitrite Nitrogen, and Total Phosphorus; added 2/month sampling for Total Suspended Solids (TSS), Total Residual Chlorine (TRC) and pH; and added grab up and down stream sampling for Salinity, Conductivity. Note: Contrary to permitting strategy (2009), receiving stream monitoring is herein set as "grab", not "composite". This decision in based on the canal -ditch discharge location being dry more often than not, and the impracticability of locating a composite sampler in remote conditions. Stream — Discharge from WTP for Outfall 001 is into McCotter Canal to Shop Branch [Stream Segment 27-115-3]. The segment [27-115-31 from source to the Pee Dee River is not currently listed as impaired in the 2012 North Carolina 303(d) List. RPA — A Reasonable Potential Analysis (RPA) was conducted on Copper, Lead and Zinc effluent parameters data because Discharge Monitoring Reports (DMRs) reported concentration above method - detection levels (MDLs) for the past four and one half (4 1/2) years (Oct 2009- Mar 2014). [See attached RPA summary sheets.] • Lead did not show reasonable potential to violate state WQS since the predicted maximum effluent concentration was less than 50% of the allowable concentration no monitoring will be required.

Description of source water(s) (i.e. groundwater, surface water) Castle Haynes Aquifer 7. Describe the treatment process(es) for the raw water: Water from the castle Haynes Aquifer is pumped up from our wells to aeration basins, where it cascades down through the top of the aerator, removing any hydrogen sulfide that may be in there. Then filter pumps take it from the basin, while being injected with potassium permanganate, to six filters; the water then goes through the greensand/anthracite filters to catch iron and manganese, now in soluble form. The water then leaves the filters and goes to the ion exchange softeners that remove calcium and magnesium. After the softeners, the water is blended with filter water to achieve proper hardness ratio, then is injected with zinc orthophosphate for corrosion control, then hypochlorite bleach, then finally ammonia to form chloramines. After the chemical injections the water goes to a million gallon storage tank, then larger pumps pump the water to the system and elevated tanks. S. Describe the wastewater and the treatment process(es) for wastewater generated by the facility The wastewater is water from our filter backwash, which mainly consists of iron and manganese. The water used for backwash is treated water consisting of chlorominated water from the system. The other part of the wastewater matrix is from our softener regeneration process, which uses filtered water and brine solution for recharging the ion beds. The backwashed or regenerated water is then discharged into our waste holding basin, where it is held for the proper settling time to achieve good effluent, then pumped to a catch basin with dechlorination tablets. 9.

Annually or when the sludge level in the backwash catch basin reaches a level of two feet, a vacuum truck is used to remove the sludge and transport it to the Havelock WWTP, where it is deposited into a dump pan. Once in the pan, the sludge is allowed time to settle and the clear water is drained to the head of the WWTP. When the sludge is dry enough to pass a paint filter test, it is then loaded and transported to the Tuscarora Land Fill in craven County. jSied/, 4, David Hemenway WTP Supervisor/ORC
