The primary train consists of a 15 MGD Super Pulsator/conventional filter facility and the secondary train consists of a 12 MGD settling basin utilizing lamella plates and sludge collection system/conventional filters. Residuals are generated from the plants from two sources: 1) Residuals removed during the sedimentation phase of the project, and 2) Residual removed by the filter. Listed below are descriptions for the generation, as well as residual handling: RESIDUALS GENERATED 15 MGD SUPERPULSATOR PLANT — The treatment process utilizes ferric sulfate and a polymer to precipitate and coagulate impurities in the raw water supply. The residuals are continuously removed from the Super Pulsator and pumped to a sludge thickener. The total residuals generated include the total suspended particles in the water, as well as any precipitant generated through the use of the coagulant and the polymer. SUPERPULSATOR FILTERS— Filters are backwashed on a routine interval based upon headloss in the filters. The headloss is accounted for by any suspended particles that are collected on top of the filters. Backwash operations remove these particles. The flow from the backwash process goes to the backwash equalization lagoon prior to any residuals handling. LAMELLA PLATE SETTLERS — In the conventional water treatment plant, the residuals are settled through the use of lamella plate settlers. The residuals are removed continuously from the bottom of the sedimentation basins where they are piped to the sludge thickener. EXISTING PLANT FILTERS The backwash operation occurs similar to the filters previously discussed with backwash flow going to the equalization basins. RESIDUALS HANDLING SYSTEM The residuals handling system consists of four basic processes, including backwash equalization, sludge thickening, sludge dewatering, and decant. As described above, the flow from the backwash operations 1 OF 2 are piped to an equalization tank. The residuals are allowed to settle to the bottom of the tank and the clarified water is decanted to the NPDES discharge in the Yadkin River. Residuals are allowed to accumulate in the bottom of the equalization tank and periodically removed by pumping and piped to the sludge thickener. The thickening operation consists of a round, clarifier type thickener. The residuals that are consistently removed from the sedimentation processes (Super Pulsator and lamella plate) are piped into the sludge thickener where they are allowed to settle and thicken on the bottom of the tank. The supernatant is decanted from the system and piped to the NPDES discharge in the Yadkin River. The thickened residuals on the bottom of the tank vary in consistency from approximately 1.5% to 4% by volume. The residuals removed from the thickener and piped to a dewatering system that consists of a drum thickener. Polymer is added to the influent flow. The residuals are thickened to a consistency of approximately 30% by volume. The residuals are then allowed to continue drying and are stored on a concrete pad adjacent to the thickening building. The residuals are periodically removed from the site and transported to the landfill for final disposal. Any decant from the thickening operation is piped back to the clarifier type thickener where it is returned to the process. 2OF2 County of Dare P.O.

The first sign of a plant upset occurred in the last week of October. The upset created heavy solids loading on the membranes decreasing treatment capability. By November 19th 2018 we had recovered from the upset and had compliant lab results. Air to the headworks was turned off during the upset, now that the event had pasted the air was turned back on, by the fourth week in November our Ammonia began to climb and then our BOD. At the time this occurred we were unaware an unknown substance had entered the plant, by turning the air back onto the headworks we placed the unknown substance into suspension which allowed it to enter the aeration zone of the plant and then the membranes, fouling them to the point of shutdown. The substance was identified and removed with its discovery on December 3rd 2018. My first call was to Atlantic Sewage for the removal and my second call was to Robbie Bullock to immediately notify the State. In order to remove the substance we had to remove the entire biological mass that the substance had attached itself to, leaving us to try and reestablish the plant's organisms in cold temperatures. A total of 72,000 gallons had to be removed at a cost of 20640.00. A cleaning consultant was brought on site and with his recommendations a new membrane cleaning system was installed allowing us to heat the cleaning water to 150 degrees, the temperature recommended by the cleaning consultant's lab; an additional 2600.00 dollars was spent on specialty cleaners to remove the substance from the membranes. To date we are still trying to reestablish the plants treatment, the trend of BOD and Ammonia failures continued from the October upset to current date. Attached are the most recent sampling results I have received, Ammonia is the only parameter out of compliance with a 70% removal rate. We are working hard to show a positive trend and hope to continue to do so. If you have any questions or concerns please feel free to contact me.

Requesting remission is not the proper procedure for contesting whether the violation(s) occurred or the accuracy of any of the factual statements contained in the civil penalty assessment document. Pursuant to N.C.G.S. § 143B-282.1(c), remission of a civil penalty may be granted only when one or more of the following five factors apply. Please check each factor that you believe applies to your case and provide a detailed explanation, including copies of supporting documents, as to why the factor applies (attach additional pages as needed). (a) one or more of the civil penalty assessment factors in N.C.G.S. 143B-282.1(b) were wrongfully applied to the T detriment of the petitioner (the assessment factors are listed in the civil penalty assessment document); (b) the violator promptly abated continuing environmental damage resulting from the violation (i.e., explain the steps that you took to correct the violation and prevent future occurrences); (c) the violation was inadvertent or a result of an accident (i.e., explain why the violation was unavoidable or something you could not prevent or prepare for); (d) the violator had not been assessed civil penalties for any previous violations; (e) payment of the civil penalty will prevent payment for the remaining necessary remedial actions (i.e., explain how payment of the civil penalty will prevent you.from performing the activities necessary to achieve compliance). EXPLANATION: Dare County Utilities is asking for remission based off option C: the violation was inadvertent or a result of an accident (i.e., explain why the violation was unavoidable or something you could not prevent or prepare for) A homeowner doing a remodel dumped his reaming paint into the sewer system, the amount of paint is unknown but it was a large enough volume to coat his tank and to clog the membranes of the 50,000gpd treatment facility. While trying to remove the paint form the membranes, staff inadvertently created polysaccharides, this occurs when a low pH cleaning solution, a high pH cleaning solution and organics combine together in the cleaning process. To avoid this the staff should have done a fresh water flush between the low pH solution and the high pH solution. ,STATE OF NORTH CAROLINA DEPARTMENT OF ENVIRONMENTAL QUALITY COUNTY OF DARE IN THE MATTER OF ASSESSMENT ) WAIVER OF RIGHT TO AN OF CIVIL PENALTIES AGAINST ) ADMINISTRATIVE HEARING AND STIPULATION OF FACTS Dare County ) Stumpy Point WWTP ) } PERMIT NO.
