Box 300 Edenton, NC 27932 Dear Ms. Knighton: John E. Skvarla, Ill Secretary October 15, 2014 Subject: Issuance of NPDES Permit NCO086291 Beaver Hill WTP Chowan County The Division of Water Resources (the Division) hereby issues the attached NPDES permit for the subject facility. 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: • Flow limit has been removed. Total Iron and Total Lead is no longer required • Added monthly turbidity monitoring. • Effluent pH monitoring is twice per month. • Total Residual Chloride (TRC) limit is 17 µg/L. 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 test method (including field certified), even if these values fall below 50 µg/L. • Updated discharge stream segment to an unnamed tributary "Filbert Creek" to Edenton Bay [26-1] , currently a Class C; NSW waterbody with Subbasin 03-01-04 of the Chowan River Basin. Whole Effluent Toxicity test results submitted during the past three years have demonstrated that the Water Treatment Plant's effluent is showing potential for causing aquatic toxicity in the receiving stream. As a result, the Town of Edenton shall perform a Discharge Alternatives Evaluation as described in Section A. (4.) of this permit. This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to the Town to comply with all NC Water Quality Standards. The permittee will be given approximately one permit cycle to evaluate and document possible treatment/discharge alternatives to eliminate aquatic toxicity. The evaluation shall be submitted with the permittee's next permit renewal application and will be carefully reviewed by the Division and the results will be used in the development of a compliance schedule or possible variance request for the Town. 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 Ms. Knighton October 15, 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 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 test method (including field certified), even if these values fall below 50µg/L. 5. Whole Effluent Toxicity (WET) testing - testing of Ceriodaphnia dubia shall be performed as 7-day pass/fail test at 90% effluent concentration, during January, April, July and October [See A. (2)]. 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 8 NPDES Permit NCO086291 4- A. (2.) CHRONIC TOXICITY PASS/FAIL MONITORING (QUARTERLY) The permittee shall conduct quarterly chronic toxicity tests using test procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay Procedure," Revised December 2010, 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 7-day pass/fail test. 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 TGP3B. Additionally, DWR Form AT-1 (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 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 monthlyear 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 this monitoring requirement 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, 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. Page 5 of 8 NPDES Permit NCO086291 a 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).

Page 7 of 8 NPDES Permit NCO086291 " b A. (4.) DISCHARGE ALTERNATIVES EVALUATION: The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity (WET) test failures. This evaluation shall assess the feasibility of all the following .alternatives. 1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater treatment plant. Approval or disapproval from the plant operator should be acquired. 2.Obtain a Non -discharge permit: Eliminate the surface water discharge by obtaining a non -discharge permit for spray irrigation, infiltration, or subsurface disposal (on -site drainfield, infiltration gallery, injection wells). 3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent to consistently pass the WET test. If this is not technically feasible or cost prohibitive, please explain and provide estimated costs. 4. Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest County, City, or Town or other wells) so the discharge or toxicity problem is eliminated. 5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment methods or operational improvements that do not produce toxic wastewaters. For example, install a recycle iron/manganese filtration system with no discharge or combine discharge with WWTP or cooling water effluents. 6. Discharge to a Larger waterbody/Perform a dilution model: Relocate the facility's discharge to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution. If applicable, perform a dilution model to receive allowance for stream dilution in WET test. 7. Combination of Alternatives: Employ any combination -of the alternatives listed above that would result in eliminating or decreasing toxicity until a more feasible solution becomes available. The evaluation shall include a present value of costs analysis for all technologically feasible options as outlined in the Division's "Engineering Alternatives Analysis Guidance Document." This Document can be found at: http://portal.ncdenr.or web/wq/swt)/ps/npdes/permits. This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to the Permttee to address aquatic toxicity in the plant effluent. Based upon the evaluation, please identify viable alternatives and present an implementation schedule and project timeline for the preferred alternative. -The Permittee shall submit the Discharge Alternatives Evaluation to the Division along with the submission of their next permit renewal application (due 6 months prior to permit expiration on June 1, 2017) to: NC DENR / Division of Water Resources / Water Quality Permitting NPDES, Wastewater Branch 1617 Mail Service Center, Raleigh, NC 27699-1617 Page 8 of 8 <^' .

Because the waste flow is <0.050 MGD, instantaneous monitoring is allowed. The facility consists of the following water and wastewater treatment units: • well water supply system • aeration basin • retention basin • ion -exchange water -softener • chemical usage consists of o chlorine o phosphate o sodium chloride brine Monthly average FLOW (MGD) — Last 36 months Ju12011-Jun2014: [Ave 0.009 MGD; Maximum, Monthly reported flow = 0.009 MGD] Toxicity —With an IWC >0.25%, this permit requires Whole Effluent Toxicity (WET) testing using Ceriodaphnia dubia to be performed as a 7-day pass/fail test at 90% effluent concentration, during January, April, July and October [TGP3B]. Ten (10) out of twelve (12) (with a pass rate of 16.7%) toxicity tests were reported as "FAIL" within three years (July201 I-Jun2014). A special condition [Section Fact Sheet Renewal 2014 -- NPDES Permit NCO086291 Page 1 A.(4.)] is added for discharge alternatives evaluation because of the four (4) toxicity failures within the most recent four (4) quarters. See attached data spreadsheet. Renewal Summary — This permit reflects discharge at Outfall 001 and renewal strategy for WTP, revised in 2009. DWR updated the facility description and Map; added parameter codes to Section A. (L); added Electronic Reporting - Discharge Monitoring Reports page [Section A. (3.)]; added monthly Turbidity monitoring; removed flow limit, Total Iron and Total Lead; added 2/month sampling for effluent pH; Total Residual Chlorine (TRC) limit was updated from 28µg/L to 17µg/L as a result of discharge to Tidal tributary with no modeling or 7Q10; and added Discharge Alternative Evaluation [Section A. (4.)] because of TOX test failure within most recent four (4) quarters. Sampling — As with the previous permit, all sampling is grab since flow is less than 30,000 GPD in accordance with 15A NCAC 2B.0505(C). Stream — Discharge from WTP for Outfall 001 is into an unnamed tributary "Filbert Creek" to Edenton Bay [Stream Segment 26-1]. The segment [26-1] 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 a half (4 '/2) years (Jan2010-Jun2014), unless otherwise noted). [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 monitoring will not be required. Iron did not show reasonable potential to violate state WQS since the predicted maximum effluent concentration was less than 50% of the allowable concentration monitoring will not be required using two (2) years of data (July20124une2014).

See Special Condition A. (X.). E = Effluent; I = Influent; U = upstream at least _ feet from the outfall; D = downstream at least _feet from the outfall. For instantaneous flow monitoring, the duration of the discharge must be reported in addition to the total flow. 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. 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 effluent concentration, during January, April, July and October [See A. (X.)]. Whole Effluent Toxicity (WET) testing - testing of Ceriodaphnia dubia shall be performed as 7-day pass/fail test at 84%effluent concentration, during January, April, July and October [See A.

September 19, 2012 Mr. Charles Weaver Division of Water Quality Surface Water Protection Section —NPDES 1617 Mail Service Center Raleigh, NC 27699-1617 Dear Mr. Weaver. Enclosed please find the original letter dated May 25, 2012 that was to transmit the Town's application for renewal of the NPDES Permit #NC0086291 for the Beaver Hill Water Treatment Plant in Edenton. As I explained in my e-mail to you earlier today, I executed the renewal application for the permit for Freemason Water Plant at the same time when I reviewed and signed the application for Beaver Hill but I now realize I inadvertently put the letter and application in our file instead of mailing to Ms. Sprinkle. I apologize for the stress this has caused and I appreciate you alerting us to the fact that our application had not been submitted. If you need more information from me, please let me know.
