Main Street Lincolnton, NC 28037 Dear Permittee: PvoROY COOPER MICHAEL S: REGAN Secret n S. JAY ZIMMERMAN REC'&ED/NCDENR/DWR Dirmlor MOOF31;8"drLLE REGIONAXOFFICE Subject: Issuance of NPDES Permit NCO084573 Lincoln County WTP Class PC-1 Lincoln County Division personnel have reviewed and approved your application for renewal of the subject permit. Accordingly, we are forwarding the attached NPDES discharge 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). The final permit includes the following significant changes from the existing permit: ➢ The monitoring requirement for iron has been removed as there is currently no water quality standard for iron. ➢ Monitoring requirements for effluent and upstream hardness were added according to policy requiring hardness sampling for facilities also monitoring for hardness - dependent metals. ➢ The whole effluent toxicity requirement has been changed from a chronic toxicity test to an acute toxicity test as the updated instream waste concentration (IWC) calculation of 0.24% requires an acute toxicity test according to toxicity monitoring policy. See Section A. (2) for details. ➢ Section A. (3) has been added because of the four toxicity failures within the most recent four quarters. ➢ Section A. (4) has been added to require electronic submission of effluent data. Federal regulations require electronic submittal of all discharge monitoring reports (DMRs). ➢ Regulatory citations have been added to the permit. ➢ An updated outfall map has been included.

Page 3 of 7 NPDES Permit Standard Conditions Page 1 of 18 PART II STANDARD CONDITIONS FOR NPDES PERMITS Section A. Definitions 2/Month Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be representative of the wastewater discharged during the sample period. 3/Week Samples are collected three times per week on three separate calendar days. These samples shall be representative of the wastewater discharged during the sample period. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et. seq. Annual Averaize The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal coliform, the geometric mean of such discharges. Arithmetic Mean The summation of the individual values divided by the number of individual values. Bypass The known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. Calendar Day The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. Calendar Week The period from Sunday through the following Saturday. Calendar Quarter One of the following distinct periods: January through March, April through June, July through September, and October through December. Composite Sample A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 mL in such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite samples may be obtained by the following methods: (1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow. (2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or Version 1110912011.1 NPDES Permit Standard Conditions Page 2 of 18 (4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. Use of this method requires prior approval by the Director. This method may only be used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply: ➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters ➢ Influent samples shall not be collected more than once per hour. ➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab samples at intervals of no greater than 20 minutes apart during any 24-hour period. ➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling period. Continuous flow measurement Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. Daily Discharge The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as the total mass of the pollutant discharged over the day. For pollutants expressed in other units of measurement, the "daily discharge" is calculated as the average measurement of the pollutant over the day. (40 CFR 122.2; see also "Composite Sample," above.) Daily Maximum The highest "daily discharge" during the calendar month. Daily Sampling Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s). DWR or "the Division' The Division of Water Resources, Department of Environment and Natural Resources. Effluent Wastewater discharged following all treatment processes from a water pollution control facility or other point source whether treated or untreated. EMC The North Carolina Environmental Management Commission EPA The United States Environmental Protection Agency Facility Closure Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this permit to be rescinded. Geometric Mean The Nth root of the product of the individual values where N = the number of individual values. For purposes of calculating the geometric mean, values of "0" (or "< [detection level]") shall be considered = 1. Grab Sample Individual samples of at least 100 mL collected over a period of time not exceeding 15 minutes. Grab samples can be collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream samples). Version 1110912011.1 NPDES Permit Standard Conditions Page 3 of 18 Hazardous Substance Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA. Instantaneous flow measurement The flow measured during the minimum time required for the flow measuring device or method to produce a result in that instance. To the extent practical, instantaneous flow measurements coincide with the collection of any grab samples required for the same sampling period so that together the samples and flow are representative of the discharge during that sampling period. Monthly Average (concentration limit) The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal coliform or other bacterial parameters or indicators, the geometric mean of such discharges. Permit Issuing Authority The Director of the Division of Water Resources. Quarterly Average (concentration limit) The arithmetic mean of all samples taken over a calendar quarter. Severe property damage Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage excludes economic loss caused by delays in production. Toxic Pollutant: Any pollutant listed as toxic under Section 3O7(a)(1) of the CWA. Upset An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. Weekly Average (concentration limit) The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar week. In the case of fecal coliform or other bacterial parameters or indicators, the geometric mean of such discharges. Section B. General Conditions 1.

Proper Operation and Maintenance The Permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the Permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the Permittee to install and operate backup or auxiliary facilities only when necessary to achieve compliance with the conditions of the permit [40 CFR 122.41(e)]. NOTE: Properly and officially designated operators are fully responsible for all proper operation and maintenance of the facility, and all documentation required thereof, whether acting as a contract operator [subcontractor] or a member of the Permittee's staff. 3. Need to Halt or Reduce not a Defense It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit [40 CFR 122.41(c)]. 4. Bypassing of Treatment Facilities a. Bypass not exceeding limitations [40 CFR 122.41(m)(2)] The Permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs b. and c. of this section. b. Notice [40 CFR 122.41(m)(3)] (1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and effect of the bypass. (2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as required in Part II.E.6. (24-hour notice). c. Prohibition of Bypass (1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take enforcement action against a Permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The Permittee submitted notices as required under Paragraph b. of this section. (2) Bypass from the collection system is prohibited and the Permit Issuing Authority may take enforcement action against a Permittee for a bypass as provided in any current or future system -wide collection system permit associated with the treatment facility. Version 1110912011.1 NPDES Permit Standard Conditions Page 8 of 18 (3) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse effects, if the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph c. (1) of this section. 5. Upsets a. Effect of an upset [40 CFR 122.41(n)(2)]: An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph b. of this condition are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. b. Conditions necessary for a demonstration of upset: Any Permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the Permittee can identify the cause(s) of the upset; (2) The Permittee facility was at the time being properly operated; and (3) The Permittee submitted notice of the upset as required in Part ll.E.6.(b) of this permit. (4) The Permittee complied with any remedial measures required under Part II.B.2. of this permit. c. Burden of proof [40 CFR 122.41(n)(4)]: The Permittee seeking to establish the occurrence of an upset has the burden of proof in any enforcement proceeding. 6. Removed Substances Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to prevent any pollutant from such materials from entering waters of the State or navigable waters of the United States except as permitted by the Commission.

[40 CFR 403.3 (i) and 0) and 15A NCAC 02H .0903(b)(11)] Interference Inhibition or disruption of the POTW treatment processes; operations; or its sludge process, use, or disposal which causes or contributes to a violation of any requirement of the Permittee's (or any satellite POTW's if different from the Permittee) NPDES, collection system, or non -discharge permit or prevents sewage sludge use or disposal in compliance with specified applicable State and Federal statutes, regulations, or permits. [15A NCAC 02H .0903(b)(14)] Pass Through A discharge which exits the POTW into waters of the State in quantities or concentrations which, alone or with discharges from other sources, causes a violation, including an increase in the magnitude or duration of a violation, of the Permittee's (or any satellite POTW's, if different from the Permittee) NPDES, collection system, or non -discharge permit. [15A NCAC 02H .0903(b)(23)] Publicly Owned Treatment Works (POTW) A treatment works as defined by Section 212 of the CWA, which is owned by a State or local government organization. This definition includes any devices and systems used in the storage, treatment, recycling and reclamation of municipal sewage or industrial wastes of a liquid nature. It also includes the collection system, as defined in 15A NCAC 2T .0402, only if it conveys wastewater to a POTW treatment plant. The term also means the local government organization, or municipality, as defined in section 502(4) of the CWA, which has jurisdiction over indirect discharges to and the discharges from such a treatment works. In this context, the organization may be the owner of the POTW treatment plant or the owner of the collection system into which an indirect discharger discharges. This second type of POTW may be referred to as a "satellite POTW organization." [15A NCAC 02H .0903(b)(26)] "Sig!►ificant Industrial User" or "S1U" An Industrial User that discharges wastewater into a publicly owned treatment works and that [15A NCAC 02H .0903(b)(33)]: 1. Discharges an average of 25,000 gallons per day or more of process wastewater to the POTW (excluding sanitary, noncontact cooling and boiler blowdown wastewaters); or 2. Contributes process wastewater which makes up five percent or more of the NPDES or non -discharge permitted flow limit or organic capacity of the POTW treatment plant. In this context, organic capacity refers to BOD, TSS and ammonia; or 3. Is subject to categorical standards under 40 CFR Part 403.6 and 40 CFR Parts 405-471; or 4. Is designated as such by the Permittee on the basis that the Industrial User has a reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, or the POTW's effluent limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options; 5. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting the criteria in paragraphs 1 or 2 of this definition above has no reasonable potential for adversely affecting the POTW's operation or for violating any pretreatment standard or requirement, the POTW's effluent limitations and conditions in its NPDES or non -discharge permit, or to limit the POTW's sludge disposal options, and thus is not a Significant Industrial User (SIU); or 6. Subject to approval under 15A NCAC 02H .0907(b), the Permittee may determine that an Industrial User meeting the criteria in paragraph 3 of this definition above meets the requirements of 40 CFR Part 403.3(v)(2) and thus is a non -significant categorical Industrial User. Section B. Publicly Owned Treatment Works (POTWs) Version 1110912011.1 NPDES Permit Standard Conditions Page 15 of 18 All POTWs must provide adequate notice to the Director of the following [40 CFR 122.42(b)]: Any new introduction of pollutants into the POTW from an indirect discharger, regardless of the means of transport, which would be subject to section 301 or 306 of CWA if it were directly discharging those pollutants; and Any substantial change in the volume or character of pollutants being introduced by an indirect discharger as influent to that POTW at the time of issuance of the permit. For purposes of this paragraph, adequate notice shall include information on (1) the quality and quantity of effluent introduced into the POTW, and (2) any anticipated impact that may result from the change of the quantity or quality of effluent to be discharged from the POTW. Section C. Municipal Control of Pollutants from Industrial Users. 1. Effluent limitations are listed in Part I of this permit. Other pollutants attributable to inputs from Industrial Users discharging to the POTW may be present in the Permittee's discharge.

The improvements do not modify the direct flow of the water through the process, and will continue to follow the conventional surface water filtration process. The notable improvements to the sludge handling facility are modifications to the gravity thickeners, new polymer feed system, installation of progressive cavity pumps with smart stator technology followed 6y an energy -efficient screw press, and conveyors to transfer dewatered solids to a dumpster or open bed truck. All filtrate and process wastewater is returned to the existing yard drain pump station to be treated through the solids handling process, All decant from the gravity thickeners exits through the floating decant arms and flow is hydraulically controlled 6y electrically actuated valves. Prior to final discharge, all decant is dechlorinated with a dechlorinating agent to comply with current chlorine residual concentrations per the existing NDPES permit, Gravity_ Thickeners The existing gravity thickeners are being retrofitted with a center column cage with two steel rake arms driven 6y a continuous torque standard shaft I HP drive. The rake arms will have adjustable 304 stainless steel squeegees to scrape the bottom of the tank. The existing tanks will 6e grouted to submerge the 8" withdrawal line and provide a sump for sludge removal. The gravity thickeners will also receive floating decanters which consist of an 8" diameter schedule 40, 304 stainless steel pipe with twenty (20) 2" diameter orifices with foam core floats attached to the decant pipe. The decant pipe will float with the water level and primarily controlled 6y the electrically actuated valve. The low water and high water level in the gravity thickener shall 6e 799.22' and 812.60', respectively, providing 1' of free board in each thickener. Progressive -Cavity Pumps A sludge handling building will 6e constructed to house the dewatering feed pumps, dewatering mechanism and conveyance system. As sludge exits the gravity thickeners, sludge can either enter the existing dewatering system for redundancy or enter the new dewatering system by simply operating two manual valves outside the existing sludge dewatering building, Sludge will enter the new sludge handling building into a header reducing down to 3" prior to entering the feed pumps. The design will utilize progressive cavity pumps to pump the settled sludge from the thickeners to a screw press. The progressive cavity pumps are designed to pump 6 to 20 GPM at a solids content of 0.8 to 1.2% with a 3 HP motor. Screw Press and Conveyance System The screw press was piloted and studied extensively on -site at the Lincoln County Water Treatment Plant using alum sludge from the current process in place for treated potable water. During the pilot, the feed solid concentration to the screw press ranged from 0.8 to 1.2%. It was determined that at a flow rate of 4 GPM, the screw handled 20 pounds per hour of dry solids. The cake produced was 24.6% dry solids. The maximum throughput of the screw press is 45 pounds per dry solids at 8 GPM; however, the cake produced was only 20% dry solids. I he screw press will be rated to handling 40 to 90 pounds per hour of dry solids at 8 to 16 GPM producing 20 to 25% dry solids. After the dewatering process, cake solids will be conveyed through a series of four (4) shafted screw conveyors to lift the solids to be discharged into a dumpster in a cover bay. Chemical Feed System Prior to sludge entering the screw press, polymer is introduced to assist with dewatering. Neat polymer will 6e dosed into an aging tank with a peristaltic pump. A 500-gallon aging tank will 6e utilized to create batches of dilute polymer. The chemical feed system is outfitted with a mixer to provide a complete mix system as well as a site glass to monitor consistency of dilute polymer make up. Dilute polymer will then be fed to the screw press with a duty/standy-6y progressive cavity pump solely used for dilute polymer. The polymer will be injected downstream of the sludge feed polymer pumps and prior to a 2" check valve designed specifically for mixing. A detention time of 45 seconds has been provided between the point of polymer injection and the screw press inlet so that the polymer can activate and optimally assist in dewatering. CONCLUSION All aforementioned equipment was installed to improve the current process of dewatering solids. The existing gravity thickeners did not have a mechanical thickening mechanism; therefore, with this addition, it can be assumed that the feed solids from the thickeners will be greater than the range observed in the pilot. Furthermore, the decanting arm will assist in assuring that a quality clarified supernate in the thickener is decanted. Previously, the peripheral decant lines were fixed withdrawing at a fixed elevation with no indication to the location of the sludge blanket. The progressive cavity and screw press tandem was selected due to the performance displayed in the pilot, efficiency and reliable operation as well as ease of operation and maintenance. A shafted conveyor was selected to lift solids because of the simplicity of the conveyors. The designed system provides redundancy as well as flexibility, All unit operations have a minimum of two installations or the ability to be expanded to two installations. The sludge handling facility will be expandable and can receive two additional progressive cavity pumps and screw presses as the need for solids handling increases. For the interim, the existing sludge handling system will be left in full working order if back up is needed. The proposed system was designed to meet the clients need with regard to redundancy, capacity, efficiency and reliability for current and future demands. With this proposed system, the Lincoln County Public Works Lincoln County Water Treatment Plant will be able to produce the desired 3.999 MGD with a method for sludge dewatering to handle the volume of sludge being produced by the sedimentation and filtration processes. Also, the existing vacuum drying bed will remain intact for redundancy of sludge removal, The existing quick disconnect from the sludge thickeners will also remain in place. Thus, the operator can utilize the drying bed as necessary or may haul wet sludge. The design will allow for a system where the operator has three (3) options of processing sludge. Lincoln County Water Treatment Plant 1.0 OBJECTIVE Sludge Handling S Recommended Operations Pri The intent of the sludge handling operations at the Lincoln County Water Treatment Plant is to provide solids handling of alum sludge in an efficient manner. In addition, the sludge handling system protocol shall provide the operations staff methods and recommended procedures to properly and efficiently operate the system described herein. 2.0 SCOPE The sludge handling system provided is a combination of unit operations including two solids thickeners, one positive displacement feed pump, a polymer system, and one dewatering press,. The previous method of dewatering was a vacuum drying bed; however the County determined that it was critical that the process no longer be weather dependent. The new sludge handling system provides a process that requires minimal power and delivers processed solids at a percent solids concentration acceptable for delivery to the local landfill. The sludge must meet the requirements of the landfill and pass the paint filter liquids test. Additional optimization of the solids handling system shall be as determined to be sensible by the operator. 3.0 SYSTEM DESCRIPTION The equipment basis of design for the sludge handling system consists of the following unit operations: 1. Thickeners (Westech) a. The thickeners allow the operator to improve the consistency and solids content of the sludge prior to conveyance to the dewatering process 2. Progressive Cavity Pump (Seepex) a. The progressive cavity pump provides the required positive displacement, metered flow pattern required for sludge processing 3. Polymer Feed System (Acrison) a. The polymer system is a batch makeup system that is controlled locally by level b. The Huber programmable logic control (PLC) provides a signal for startup and for the feed pumps to deliver the necessary polymer dose to the sludge 4. Screw Press (Huber) a. The screw press dewaters the sludge to a cake product 5. Conveyance (Custom Conveyors) a. The conveyors transport dewatered cake to an owner selected dewatering bin The Westech thickeners, Seepex feed pump, Acrison polymer system, Huber screw press, and Huber conveyors work together to provide a complete process. 4.0 OPERATION 2 Sludge Handling System ounty Water Treatment Plant Recommended Operations Protocol 4.1 Thickeners The sludge thickener mechanisms and their operation are critical in the success of the solids dewatering process. The thickeners are fit with mechanical thickening devices at the bottom of the conical tanks. The bottom of the conical tanks, where the 8 inch diameter effluent sludge pipe is located, is at approximate elevation of 780 feet. The grade elevation at the tanks is approximately 798 feet, thus the depth at which sludge can accumulate is upward of 18 vertical feet. In addition, the decant mechanism for the water allows for the decanting of the tank to a low water level (LWL) of near elevation 799. The top of wall of the sludge thickeners is near 814.8 allowing for over 13 feet of wastewater from the water treatment plant to accumulate from the backwashing of filters and the removal of solids in the sedimentation process. The operation of the sludge thickeners is critical to the dewatering process. The operator controls the thickness of the solids with the rotating thickener and the available pressure (head) in the tanks. The water level in the tank feeding the sludge dewatering process provides backpressure on the sludge feed pumps. The 8 inch diameter sludge feed line operated at flow rates between 8 and 20 gallons per minute provides little frictional headless in the pipe due to velocity. The velocity of the sludge in the 8 inch pipe at 20 gallons per minute is near 0.13 feet per second. However, the thixotropic properties of the sludge may create difficulties when starting the dewatering process, specifically when it has not been operational for periods greater than 12 hours. 4.2 Progressive Cavity Pump and Polymer System The sludge feed pump suction is located at approximate elevation of 801.5 feet. Thus, the operator shall, at a minimum, allow for the pumps to have a flooded suction. For operation of the dewatering system, the tank from which the operator elects to process solids should have a water level sufficient to overcome the head loss, which is minimal due to the low velocity in the 8 inch pipe, and the viscous/thixotropic properties of the sludge._ The pressure of the tanks should read on the pressure gauge on the suction side of the pump to indicate to the operator that sufficient head is present for beginning the dewatering process. It is recommended that the tank water level be at a minimum elevation of 805 feet for the startup of the dewatering system. Continuous use by the operator and logging of startup data should allow the operator to increase or decrease this water level for startup dependent upon the comfort level with the sludge consistency and backpressure on the pump. Upon process initiation, the sludge (plug) valve from the thickener which is to be utilized for sludge dewatering shall be opened. The operator shall fluidize the influent sludge line by turning on the water connection at the suction of the pump. The water will provide lubrication of the pipe for improved sludge conveyance. 3 Sludge Handling S Lincoln County Water Treatment Plant Recommended Operations Pri The pressure gauge on the suction side of the pump shall be utilized to determine when sufficient head pressure has built up behind the pump for startup. The operator may replace the existing pressure gauge with a combination vacuum gauge to insure that a vacuum has not been created, thereby protecting the progressive cavity pumps from running dry. The operator may elect to wait until adequate sludge consistency is being conveyed to the screw press before initiating polymer system injection. Reducing the polymer injection prior to the sludge becoming consistency may waste costly polymer. Once the sludge is actively being conveyed in the piping system, the polymer injection can be initiated. All water and inconsistent sludge content prior to polymer injection and the dewatering of the sludge shall flow as designed to the yard drain pump station that recycles the contents to the thickener. Additional flushing quick connections near the thickener on the conveyance piping are recommended should plugging.of the line become frequent during shut down periods. Existing connections to the 8 inch pipe make this connection easily constructed and the conveyance line cleared with the water pressure of the line. The thickener level must be elevated to force the water pressure to move and lubricated around the sludge travelling toward the pump, in lieu of simply filling the tank where the pressure may be lower. 4.3 Screw Press and Conveyance After initiation of the process and confirmation of active sludge movement with consistency, the process may then be operated and controlled by the Huber controller. The controller is designed to operate the polymer system, dewatering system and dried solids conveyance system. 5.0 SYSTEM TERMINATION Process termination is another critical component of the operations. Due to the known properties of water treatment sludge, issues may develop in the feed piping that cause difficulties during the subsequent startup. Operators shall fluidize the sludge feed line, and process sludge to the drain through the screw press._ The wasted water and sludge will then be recycled back to the thickener through the yard drain pump station. The feed line pressure gauge shall be monitored and the pressure supplied by the water should increase the pressure in the line to indicate good fluidization. 6.0 TESTING AND REPORTING It is recommended that multiple data entries be logged with each startup. These factors will aid in the optimization of the process not only by present operators but by future operations staff. The entries should include, but not be limited to: 1. Thickener utilized for dewatering process (1 or 2); Sludge Handling System my Water Treatment Plant Recommended Operations Protocol z. vv aver elevation in thickener at startup; 3. Time between shutdown and startup; 4. Percent solids influent; 5. Polymer usage; 6. Average sludge flow rate; 7. Percent solids processed; 8. Process run time; 9. Faults encountered during processing; 10. Total sludge volume processed; 11. Thickener run times; and 12. Sludge line pressure. Data logging, whether in the PLC or in tabular form, allows operators to constructively troubleshoot. Process optimization is made more efficient, and quality information becomes readily accessible to management purposes.- Many other data points should also be evaluated and the operator should use good judgment in determining the necessary additional points to monitor. The operator shall utilize the data log to make decisions on the run times for the thickener mechanisms._ It is likely that the thickener should not be run at all times, as the thickening of the alum sludge when not processing solids may create a consistency that is difficult to convey and process. -In addition, the solids may be forced into the lower elevations of the pipe between the thickener and the feed pump and become consolidated creating problems for the subsequent startup. Other actions that aids in the clearing of this sludge line are the flushing of the line prior to process termination and utilizing the available head pressure in the tanks to feed the pumps. Modifications to the sludge handling process operations protocol shall be made as data becomes available for analysis. Improved comprehension of the specific installation through the data collected shall provide improved operations. 7.0 SUMMARY The sludge handling system shall be operated to meet the requirement for delivery of the dewatered product to the local landfill. The operations staff must be cognizant of the aforementioned items to provide a system that functions properly and efficiently as designed. Data shall be recorded and tracked so that changes can be made to the sludge handling system. It is recommended that process changes be made immediately when the sludge handling system is not operating as intended. These changes shall be at the discretion of the operator responsible for the system at that time. Efficient sludge handling operations at the Lincoln County Water Treatment Plant is an integral process to the overall treatment process and shall be operated with the recommendations provided, data collected and experience gained while the sludge handling system is in operation. 5 Allocco, Marcia From: Allocco, Marcia Sent: Tuesday, October 28, 2014 10:39 AM To: Sledge, Bob Cc: Parker, Michael Subject: NC0084573 - Lincoln County WTP renewal Since the Lincoln County WTP is not a major facility MRO does not plan to provide a formal staff report as part of the permit renewal.

The pH shall not be less than 6.0 standard units, nor greater than 9.0 standard units. 3. Monitoring should be performed in conjunction with toxicity testing. 4. See Condition A. (2.) for toxicity testing requirements. Toxicity testing should be performed during the months of March, June, September and December, and sampling should coincide with sampling for parameters covered by footnote 3. There shall be no floating solids or foam in other than trace amounts. All samples must be collected from a typical discharge event. .r Permit NCO084573 A. (2.) CHRONIC TOXICITY MONITORING (QUARTERLY) The permittee shall conduct guarterly 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 dAia 7day pass/fail test. The test§ will be performed during the months of March, June, September and December. 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. NPDES Permit Standard Conditions Page 1 of 18 PART II STANDARD CONDITIONS FOR NPDES PERMITS Section A. Definitions 2/Month Samples are collected twice per month with at least ten calendar days between sampling events. These samples shall be representative of the wastewater discharged during the sample period. 3/Week Samples are collected three times per week on three separate calendar days. These samples shall be representative of the wastewater discharged during the sample period. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act (CWA), as amended, 33 USC 1251, et. seq. Annual Average The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal coliform, the geometric mean of such discharges. Arithmetic Mean The summation of the individual values divided by the number of individual values. B ass The known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. Calendar Day The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. Calendar Week The period from Sunday through the following Saturday. Calendar Quarter One of the following distinct periods: January through March, April through June, July through September, and October through December. Composite Sample A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite samples may be obtained by the following methods: (1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow. (2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and Version 712009 NPDES Permit Standard Conditions Page 2 of 18 totalizer, and the preset gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. Use of this method requires prior approval by the Director. This method may only be used in situations where effluent flow rates vary less than 15 percent. The following restrictions also apply: ➢ Influent and effluent grab samples shall be of equal size and of no less than 100 milliliters ➢ Influent samples shall not be collected more than once per hour. ➢ Permittees with wastewater treatment systems whose detention time < 24 hours shall collect effluent grab samples at intervals of no greater than 20 minutes apart during any 24-hour period. ➢ Permittees with wastewater treatment systems whose detention time exceeds 24 hours shall collect effluent grab samples at least every six hours; there must be a minimum of four samples during a 24-hour sampling period. Continuous flow measurement Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. Daily Discharge The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all grab samples collected during that period. (40 CFR 122.2) Daily Maximum The highest "daily discharge" during the calendar month. Daily Sampling Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the permit. Sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s). DWQ or "the Division" The Division of Water Quality, Department of Environment and Natural Resources. EMC The North Carolina Environmental Management Commission. EPA The United States Environmental Protection Agency Facility Closure Cessation of all activities that require coverage under this NPDES permit. Completion of facility closure will allow this permit to be rescinded. Geometric Mean The Nth root of the product of the individual values where N = the number of individual values. For purposes of calculating the geometric mean, values of "0" (or "< [detection level]' shall be considered = 1. Version 712009 NPDES Permit Standard Conditions Page 3 of 18 Grab Sample Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream samples). Hazardous Substance Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the CWA. Instantaneous flow measurement A measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. Monthly Average (concentration limitl The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal coliform, the geometric mean of such discharges. Permit Issuing Authority The Director of the Division of Water Quality. Quarterly Average (concentration limit) The average of all samples taken over a calendar quarter. Severe property damagce Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage excludes economic loss caused by delays in production. Toxic Pollutant: Any pollutant listed as toxic under Section 307(a)(1) of the CWA. Upset An incident beyond the reasonable control of the Permittee causing unintentional and temporary noncompliance with permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

Site was well operated and maintained at the time of the site visit. Sodium Thiosulfate is added (broadcast) at a rate of 1 gallon/35,000 gallons backwash water to the filter basins at time of flushing . Backwash occurs at 96 hour intervals for each basin. There was vacume filter material stored outside the basin at the time of the site visit. Weather and moisture conditions have some effect on the solids concentration that the filter is capable off. Air drying adjacent to the concrete pad is sometimes used as a remidy to this issue. There was no evidence of migration of materials from the concrete vacume pad filter area. The approximate discharge from the clarifiers is 60,0000 - 70,000 gallons per 48 hour period.

If you have not already done so, it is suggested that you thoroughly read the Permit. Of particular importance is Page 4. Page 4 sets forth the effluent limitations and monitoring requirements for your discharge. Your discharge must not exceed any of the limitations set forth. The section headed "Monitoring Requirements" describes the measurement frequencies, sample types and sampling locations. Upon commencement of your discharge (or operation), you must initiate the required monitoring. The monitoring results must be entered on reporting forms furnished or approved by this Agency. For new permits/facilities, the Division may supply an initial small stock of these forms; however, if you fail to receive the forms, please contact this Office as quickly as possible. The forms, including directions for their completion, and other important information are also available at htti)://h2o.enr.state.ne.us/NPDES/documents.html. It is imperative that all applicable parts be completed, and the original and one copy be submitted as required. Please be advised that an annual fee may be required for your facility; if so, you will receive a statement from our Raleigh Office. It is imperative that the fee be paid in a timely manner so as to prevent enforcement action or possible revocation of your permit. The remaining parts of the Permit set forth definitions, general conditions and special conditions applicable to the operation of wastewater treatment facilities and/or discharge(s). The conditions include special reporting requirements in the event of noncompliance, bypasses, treatment unit/process failures, etc. Also addressed are requirements for a certified wastewater treatment plant operator if you are operating wastewater treatment facilities.

To maintain compliance with discharge limitations, proper operation and maintenance of a wastewater treatment facility and the development of a process control program are essential. For'those facilities having chlorine tablet disinfection, please be advised that chlorine tablets approved for wastewater treatment use must be used; swimming pool tablets are not approved. Also, be advised that DWQ staff need to have access to the facility's discharge point into the receiving stream; please maintain a path along the outfall line to facilitate that access. Failure to comply with the terms and conditions of an NPDES Permit subjects the Permittee to enforcement action pursuant to Section 143-215.6 of the North Carolina General Statutes. A civil penalty of up to $25,000 per violation (and/or criminal penalties) may be assessed for such violations. If you find at any time that you are unable to comply with the terms and conditions of the Permit, you should contact this Office immediately. A Special Order by Consent (SOC) may be necessary while pursuing action to obtain compliance. As a final note, an NPDES Permit is normally issued for a five-year period. Permits are not automatically renewed. Renewal requests must be submitted to this Agency no later than 180 days prior to expiration. Please make note of the expiration date of your Permit. This date is set forth on Page 1 of the Permit. Also note that NPDES Permits are not automatically transferable. If you, as the Permittee, cease to need this Permit, then you should request that the Division of Water Quality rescind the Permit or request that DWQ reissue the Permit to another party, if necessary. As mentioned previously, the purpose of this letter is to advise you of the importance of your NPDES Permit.

Definitions 2/Month Samples are collected twice per month with at least ten calendar days between sampling events. 3/Week Samples are collected three times per week on three separate calendar days. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq. Annual Average The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar year. In the case of fecal coliform, the geometric mean of such discharges. Arithmetic Mean The summation of the individual values divided by the number of individual values. Bypass The known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. Calendar Dav The period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. Calendar Quarter One of the following distinct periods: January through March, April through June, July through September, and October through December. Composite Sams A sample collected over a 24-hour period by continuous sampling or combining grab samples of at least 100 ml in such a manner as to result in a total sample representative of the wastewater discharge during the sample period. The Director may designate the most appropriate method (specific number and size of aliquots necessary, the time interval between grab samples, etc.) on a case -by -case basis. Samples may be collected manually or automatically. Composite samples may be obtained by the following methods: (1) Continuous: a single, continuous sample collected over a 24-hour period proportional to the rate of flow. (2) Constant time/variable volume: a series of grab samples collected at equal time intervals over a 24.hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (3) Variable time/constant volume: a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the preset gallon interval between sample collection fixed at no greater than 1 /24 of the expected total daily flow at the treatment system, or (4) Constant time/constant volume: a series of grab samples of equal volume collected over a 24-hour period at a constant time interval. This method may only be used in situations where effluent flow rates vary less than 15 percent. The grab samples shall be taken at intervals of no greater than 20 minutes apart during any 24-hour period and must be of equal size and of no less than 100 milliliters. Use of this method requires prior approval by the Director. Version 612012003 NPDES Permit Requirements Page 2 of 16 In accordance with (4) above, influent grab samples shall not be collected more than once per hour. Effluent grab samples shall not be collected more than once per hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at intervals evenly spaced over the 24-hour period that are equal in number of hours to the detention time of the system in number of days. However, the interval between effluent grab samples may not exceed six hours nor the number of samples less than four during a 24-hour sampling period. Continuous flow measurement Flow monitoring that occurs without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. Daily Discharge The discharge of a pollutant measured during a calendar day or any 24-hour period that reasonably represents the calendar day for purposes of sampling. For pollutants measured in units of mass, the "daily discharge" is calculated as the total mass of the pollutant discharged over the day. The "daily discharge" concentration comprises the mean concentration for a 24-hour sampling period as either a composite sample concentration or the arithmetic mean of all grab samples collected during that period. (40 CFR 122.3) Daily Maximum The highest "daily discharge" during the calendar month. Daily Sampling Parameters requiring daily sampling shall be sampled 5 out of every 7 days per week unless otherwise specified in the permit. The Division expects that sampling shall be conducted on weekdays except where holidays or other disruptions of normal operations prevent weekday sampling. If sampling is required for all seven days of the week for any permit parameter(s), that requirement will be so noted on the Effluent Limitations and Monitoring Page(s). DWO or "the Division" The Division of Water Quality, Department of Environment and Natural Resources. EMC The North Carolina Environmental Management Commission. Facility Closure The cessation of wastewater treatment at a permitted facility, or the cessation of all activities that require coverage under the NPDES. Completion of facility closure will allow this permit to be rescinded. Geometric Mean The Nth root of the product of the individual values where N = the number of individual values. For purposes of calculating the geometric mean, values of "0" (or "< [detection level]' shall be considered = 1. Grab Sample Individual samples of at least 100 ml collected over a period of time not exceeding 15 minutes. Grab samples can be collected manually. Grab samples must be representative of the discharge (or the receiving stream, for instream samples). Hazardous Substance Any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. Instantaneous flow measurement A measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. Version 612012003 NPDES Permit Requirements Page 3 of 16 Monthly Average (concentration limit) The arithmetic mean of all "daily discharges" of a pollutant measured during the calendar month. In the case of fecal coliform, the geometric mean of such discharges. Permit IssuingAuthorMi The Director of the Division of Water Quality. Quarterly Average (concentration limitl The average of all samples taken over a calendar quarter. Severe property damage Substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage excludes economic loss caused by delays in production. Toxic Pollutant: Any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act. U set An incident beyond the reasonable control of the Pernuttee causing unintentional and temporary noncompliance with permit effluent limitations and/or monitoring requirements. An upset does not include noncompliance caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation.

Proper Operation and Maintenance The Permittee shall at all times provide the operation and maintenance resources necessary to operate the existing facilities at optimum efficiency. The Permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the Permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the Permittee to install and operate backup or auxiliary facilities only when necessary to achieve compliance with the conditions of the permit [40 CFR 122.41 (e)]. 3. Need to Halt or Reduce not a Defense It shall not be a defense for a Permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit (40 CFR 122.41 (CA. 4. Bypassing of Treatment Facilities a. Bypass not exceeding limitations [40 CFR 122.41 (m) (2)] The Permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs b. and c. of this section. b. Notice [40 CFR 122.41 (m) (3)] (1) Anticipated bypass. If the Permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and effect of the bypass. (2) Unanticipated bypass. The Permittee shall submit notice of an unanticipated bypass as required in Part II. E. 6. (24-hour notice). c. Prohibition of Bypass (1) Bypass from the treatment facility is prohibited and the Permit Issuing Authority may take enforcement action against a Permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime.

Pan II Page 1 of 14 PART II STANDARD CONDITIONS FOR NPDES PERMITS SECTION A. DEFINITIONS 1. Permit Issuing Authority The Director of the Division of Water Quality. 2. DEM or "the Division" Means the Division of Water Quality, Department of Environment, Health and Natural Resources. 3. EMC Used herein means the North Carolina Environmental Management Commission. 4. Act or "the Act" The Federal Water Pollution Control Act, also known as the Clean Water Act, as amended, 33 USC 1251, et. seq. 5. Mass/Day Measurements a. The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found each day of the month and then dividing this sum by the number of days the tests were reported. The limitation is identified as "Monthly Average" in Part I of the permit. b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the week and then dividing this sum by the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit. c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit. d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar year on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the year and then dividing this sum by the number of days the tests were reported. This limitation is defined as "Annual Average" in Part I of the permit. Part II Page 2 of 14 6. Concentration Measurement a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit. b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the -samples collected during that calendar day. The average weekly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If only one sample is taken during any calendar day the concentration of pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Part I of the permit. d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such year (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day . The average yearly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is identified as "Annual Average" under "Other Limits" in Part I of the permit. e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average concentration" for the discharge. It is identified as "daily average" in the text of Part I. f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit. g. A calendar quarter is defined as one of the following distinct periods: January through March, April through June, July through September, and October through December. Part II Page 3 of 14 7. Other Measurements a. Flow, (MGD): The flow limit expressed in this permit is the 24 hours average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month. b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. 8. Types of Samples a. Composite Sample: A composite sample shall consist of: (1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the present gallon interval between sample collection fixed at no greater than 1 /24 of the expected total daily flow at the treatment system, or (3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow. In accordance with (1) above, the time interval between influent grab samples shall be no greater than once per hour, and the time interval between effluent grab samples shall be no greater than once per hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals evenly spaced over the 24 hour period which are equal in number of hours to the detention time of the system in number of days. However, in no case may the time interval between effluent grab samples be greater than six (6) hours nor the number of samples less than four (4) during a 24 hour sampling period. b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be representative of the discharge or the receiving waters. 9. Calculation of Means a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one (1). c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its respective flow divided by the summation of the respective flows. Part H Page 4 of 14 10. Calendar Day A calendar day is defined as the period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. 11. Hazardous Substance A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. 12. Toxic Pollutant A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act. SECTION B. GENTERAL CONDITIONS 1.

The authority to operate the facility under previously issued permits bearing this number is no longer effective. ) The conditions, requirements, terms, and provisions of this permit authorizing discharge under the National Pollutant Discharge Elimination System govern discharges from this facility. SECTION C. OPERATION AND MAINTENANCE OF POLLUTION CONTROLS 1. Certified Operator Pursuant to Chapter 9OA44 of North Carolina General Statutes, and upon classification of the facility by the Certification Commission, the permittee shall employ a certified wastewater treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such operator must hold a certification of the grade equivalent to or greater than the classification assigned to the wastewater treatment facilities by the Certification Commission_ The permittee must also employ a certified back-up operator of the appropriate type and any grade to comply with the conditions of Title 15A, Chapter 8A .0202. The ORC of the facility must visit each Class 1 facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and must properly manage and document daily operation and maintenance of the facility and must comply with all other conditions of Title 15A, Chapter 8A .0202. Once the facility is classified, the permittee shall submit a letter to the Certification Commission which designates the operator in responsible charge within thirty days after the wastewater treatment facilities are 50% complete. 2. Proper Operation and Maintenance The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit. Part II Page 8 of 14 3. Need to Halt or ht-duce not a Defense It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit. 4. Bypassing of Treatment Facilities a. Definitions (1) 'Bypass" means the known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which -does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of this section. c. Notice (1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and affect of the bypass. (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part II, E. 6. of this permit. (24 hour notice). d. Prohibition of Bypass (I) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The permittee submitted notices as required under Paragraph c. of this section. (2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph d. (1) of this section. Part H Page 9 of 14 5. Upsets a. Definition. "Upset " means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent Iimitations if the requirements of paragraph c. of this condition are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the cause(s) of the upset; (2) The permittee facility was at the time being properly operated; and (3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit. (4) The permittee complied with any remedial measures required under Part I1, B. 2. of this permit. d. Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof. 6. Removed Substances Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to prevent any pollutant from such materials from entering waters of the State or navigable waters of the United States. The permittee shall comply with all existing federal regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued by the Permit Issuing Authority for the utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the regulation, even if the permit is not modified to incorporate the requirement. The permittee shall notify the Permit Issuing Authority of any significant change in its sludge use or disposal practices. 7. Power Failures The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation, Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the discharge of untreated or inadequately treated wastes during electrical power failures either by means of alternate power sources, standby generators or retention of inadequately treated effluent. Part H Page 10 of 14 SECTION D. MONITORING AND RECORDS 1. Representative Sampling Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Samples collected at a frequency less than daily shall be taken on a day and time that is characteristic of the discharge over the entire period which the sample represents. All samples shall be taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without notification to and the approval of the Permit Issuing Authority. 2. Reporting Monitoring results obtained during the previous month(s) shall be summarized for each month and reported on a monthly Discharge Monitoring Report (DMR) Form (DEM No. MR 1, 1.1, 2, 3) or alternative forms approved by the Director, DEM, postmarked no later than the 30th day following the completed reporting period. 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. Duplicate signed copies of these, and all other reports required herein, shall be submitted to the following address: Division of Water Quality Water Quality Section ATTENTION: Central Files 1617 Mail Service Center Raleigh, North Carolina 27699-1617 3. Flow Measurements Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements are consistent with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a maximum deviation of less than + 10% from the true discharge rates throughout the range of expected discharge volumes.

There does not appear to be any new alternatives for wastewater disposal since the permit was last issued. A the time the original NPDES Permit was issued, this Office recommended that the outfall be extended to the mouth of the small, narrow cove on Lake Norman where the WTP is located. The reason for this request is that the original proposed location for the outfall (on the shoreline of the lake) presented some potential problems, which included poor mixing of the effluent with the receiving waters possibly resulting in elevated in -stream turbidity levels. An alternate discharge location was chosen during the original site visit (1994) and the alternate discharge location (at the mouth of the Little Creek Cove) received tentative approval from the MRO-Public Water Supply Staff. This location would have provided a much better mixing location without affecting the nearby water intake and should be readily accessible with a minimum amount of additional effort. The proposed outfall location would also have accommodated the normal winter lake draw down (elevation 752 feet) in allowing continuous mixing with the Lake waters. For some unknown reason, however, Duke Power never granted approval for the line to encroach within the project boundary of the Lake (below the full pond elevation). Duke's contention was that the line would not be protected from exposure during times of maximum draw down (elevation 748 feet), which coincidentally, has not occurred in the past 20 years. For this reason, the WTP's line was extended to the full pond elevation and that is where the discharge enters the Lake. Pending concurrence from the DEH and receipt and approval of the WLA from the TSB, it is recommended that an NPDES Permit be reissued as requested. hAdsr\dsr00\hncty.wtp Signature of Report Preparer Water Quality Regional D e F PState of North Carolina Ma Da Department of Environment � UNMENTi � L77W • • and Natural Resources �` R OUR('Fg %P _ Division of Water Quality DEC 28 1999 James B.

Thank you for submitting this package. The permit renewal for this facility will be assigned to a member of the NPDES Unit staff. That staff member will contact you if further information is needed to complete the permit renewal. Please note that the NPDES Unit has several vacant positions. This staff shortage has lasted for over a year and is delaying all permit renewals. Our remaining permit writers are currently reviewing Authorizations to Construct, speculative limit requests, major permit modifications and 201 plan updates ahead of permit renewals. This is necessary due to a variety of factors, including mandatory deadlines in the statutes which govern our program. If this staff shortage delays reissuance of NC0084573, the existing requirements in your permit will remain in effect until the permit is renewed (or the Division takes other action). We appreciate your patience and understanding while we operate with a severely depleted staff.

A NCDENR NORTH CAROLINA DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES Subject: Renewal of NPDES Permit NCO084573 LINCOLN COUNTY WTP LINCOLN County Dear Permittee: The subject permit expires on June 30. 2000. North Carolina Administrative Code 15A NCAC 2H.0105(e) requires that an application for permit renewal be filed at least 180 days prior to expiration of the current permit. To satisfy this requirement, your renewal package must be sent to the Division postmarked no later than January 2, 2000. Failure to request renewal of the permit by this date will result in a civil assessment of at least $250.00. Larger penalties may be assessed depending upon the delinquency of the request. If any wastewater discharge will occur after June 30. 2000 (or if continuation of the permit is desired), the current permit must be renewed. Operation of wastewater treatment works or continuation of discharge after June 30, 2000 would violate North Carolina General Statute 143-215.1 and could result in assessment of civil penalties of up to $25,000 per day. If all wastewater discharge has ceased at your facility and you wish to rescind this permit, contact Robert Farmer of the Division's Compliance Enforcement Unit at (919) 733-5083, extension 531. You may also contact the Mooresville Regional Office at (704) 663-1699 to begin the rescission process. Use the enclosed checklist to complete your renewal package.

The proposed project will be to construct a discharge line for backwash water from the County's water treatment plant. The County has been issued a NPDES discharge permit, NC0084573. The discharge will be located just off of Tree Farm Road (SR 1725) in eastern Lincoln County. The discharge will consist of a 12-inch diameter HDPE polyethylene pipe, installed along the lake bottom, with the discharge end being approximately 150' off the shore line. On the shore, a precast concrete manhole will be installed to feed the discharge line. Discharge to the line will be by gravity flow. The pipe will be installed approximately 24 inches below the lake bottom until the depth is below that of the low water elevation of the lake, at which point the line lie directly on the lake bottom and be anchored with grout bags. A screen will be installed over the end of the line to prohibit fish and other obstructions from entering the pipe. In accordance with Duke Power conveyance application program, I would like to notify your agency of our construction. Please call or write me regarding any necessary approvals or permits that will be required for this construction, or if you have any questions. Sincerely, Douglas Chapman)'P.E.

The "monthly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month. It is therefore, an arithmetic mean found by adding the weights of the pollutant found each day of the month and then dividing this sum by the number of days the tests were reported. The limitation is identified as "Monthly Average" in Part I of the permit. b. The "weekly average discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar week (Sunday - Saturday) on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such week. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the week and then dividing this sum by the number of days the tests were reported. This limitation is identified as "Weekly Average" in Part I of the permit. c. The "maximum daily discharge" is the total mass (weight) of a pollutant discharged during a calendar day. If only one sample is taken during any calendar day the weight of pollutant calculated from it is the "maximum daily discharge." This limitation is identified as "Daily Maximum," in Part I of the permit. d. The "average annual discharge" is defined as the total mass of all daily discharges sampled and/or measured during the calendar year on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such year. It is, therefore, an arithmetic mean found by adding the weights of pollutants found each day of the year and then dividing this sum by the number of days the tests were reported. This limitation is defined as "Annual Average" in Part I of the permit. Part II Page 2 of 14 OTI. MITO M, f M 9 s M- a. The "average monthly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar month on which daily discharges are sampled and measured, divided by the number of daily discharges sampled and/or measured during such month (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average monthly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar month. This limitation is identified as "Monthly Average" under "Other Limits" in Part I of the permit. b. The "average weekly concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar week (Sunday/Saturday) on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such week (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average weekly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar week. This limitation is identified as "Weekly Average" under "Other Limits" in Part I of the permit. c. The "maximum daily concentration" is the concentration of a pollutant discharge during a calendar day. If only one sample is taken during any calendar day the concentration of pollutant calculated from it is the "Maximum Daily Concentration". It is identified as "Daily Maximum" under "Other Limits" in Part I of the permit. d. The "average annual concentration," other than for fecal coliform bacteria, is the sum of the concentrations of all daily discharges sampled and/or measured during a calendar year on which daily discharges are sampled and measured divided by the number of daily discharges sampled and/or measured during such year (arithmetic mean of the daily concentration values). The daily concentration value is equal to the concentration of a composite sample or in the case of grab samples is the arithmetic mean (weighted by flow value) of all the samples collected during that calendar day. The average yearly count for fecal coliform bacteria is the geometric mean of the counts for samples collected during a calendar year. This limitation is identified as "Annual Average" under "Other Limits" in Part I of the permit. e. The "daily average concentration" (for dissolved oxygen) is the minimum allowable amount of dissolved oxygen required to be available in the effluent prior to discharge averaged over a calendar day. If only one dissolved oxygen sample is taken over a calendar day, the sample is considered to be the "daily average concentration" for the discharge. It is identified as "daily average" in the text of Part I. f. The "quarterly average concentration" is the average of all samples taken over a calendar quarter. It is identified as "Quarterly Average Limitation" in the text of Part I of the permit. g. A calendar quarter is defined as one of the following distinct periods: January through March, April through June, July through September, and October through December. Part II Page 3 of 14 7. Other Measurements a. Flow, (MGD): The flow limit expressed in this permit is the 24 ,hours average flow, averaged monthly. It is determined as the arithmetic mean of the total daily flows recorded during the calendar month. b. An "instantaneous flow measurement" is a measure of flow taken at the time of sampling, when both the sample and flow will be representative of the total discharge. c. A "continuous flow measurement" is a measure of discharge flow from the facility which occurs continually without interruption throughout the operating hours of the facility. Flow shall be monitored continually except for the infrequent times when there may be no flow or for infrequent maintenance activities on the flow device. a. Composite Sample: A composite sample shall consist of- (1) a series of grab samples collected at equal time intervals over a 24 hour period of discharge and combined proportional to the rate of flow measured at the time of individual sample collection, or (2) a series of grab samples of equal volume collected over a 24 hour period with the time intervals between samples determined by a preset number of gallons passing the sampling point. Flow measurement between sample intervals shall be determined by use of a flow recorder and totalizer, and the present gallon interval between sample collection fixed at no greater than 1/24 of the expected total daily flow at the treatment system, or (3) a single, continuous sample collected over a 24 hour period proportional to the rate of flow. In accordance with (1) above, the time interval between influent grab samples shall be no greater than once per hour, and the time interval between effluent grab samples shall be no greater than once per hour except at wastewater treatment systems having a detention time of greater than 24 hours. In such cases, effluent grab samples may be collected at time intervals evenly spaced over the 24 hour period which are equal in number of hours to the detention time of the system in number of days. However, in no case may the time interval between effluent grab samples be greater than six (6) hours nor the number of samples less than four (4) during a 24 hour sampling period. b. Grab Sample: Grab samples are individual samples collected over a period of time not exceeding 15 minutes; the grab sample can be taken manually. Grab samples must be representative of the discharge or the receiving waters. 9. Calculation of Means a Arithmetic Mean: The arithmetic mean of any set of values is the summation of the individual values divided by the number of individual values. b. Geometric Mean: The geometric mean of any set of values is the Nth root of the product of the individual values where N is equal to the number of individual values. The geometric mean is equivalent to the antilog of the arithmetic mean of the logarithms of the individual values. For purposes of calculating the geometric mean, values of zero (0) shall be considered to be one (1). Part II Page 4 of 14 c. Weighted by Flow Value: Weighted by flow value means the summation of each concentration times its respective flow divided by the summation of the respective flows. 10. Calendar Day A calendar day is defined as the period from midnight of one day until midnight of the next day. However, for purposes of this permit, any consecutive 24-hour period that reasonably represents the calendar day may be used for sampling. .. ._"�. �I M.• A hazardous substance means any substance designated under 40 CFR Part 116 pursuant to Section 311 of the Clean Water Act. IPA UMM of A toxic pollutant is any pollutant listed as toxic under Section 307(a)(1) of the Clean Water Act. The permittee must comply with all conditions of this permit. Any permit noncompliance constitutes a violation of the Clean Water Act and is grounds for enforcement action; for permit termination, revocation and reissuance, or modification; or denial of a permit renewal application. a. The permittee shall comply with effluent standards or prohibitions established under section 307(a) of the Clean Water Act for toxic pollutants and with standards for sewage sludge use or disposal established under section 405(d) of the Clean Water Act within the time provided in the regulations that establish these standards or prohibitions or standards for sewage sludge use or disposal, even if the permit has not yet been modified to incorporate the requirement. b. The Clean Water Act provides that any person who violates a permit condition is subject to a civil penalty not to exceed $25,000 per day for each violation. Any person who negligently violates any permit condition is subject to criminal penalties of $2,500 to $25,000 per day of violation, or imprisonment for not more than 1 year, or both. Any person who knowingly violates permit conditions is subject to criminal penalties of $5,000 to $50,000 per day of violation, or imprisonment for not more than 3 years, or both.

R9030"Mrom WTIMM All previous National Pollutant Discharge Elimination System Permits issued to this facility, whether for operation or discharge, are hereby revoked by issuance of this permit. [The exclusive authority to operate this facility arises under this permit. The authority to operate the facility under previously issued permits bearing this number is no longer effective. ] The conditions, requirements, terms, and provisions of this permit authorizing discharge under the National Pollutant Discharge Elimination System govern discharges from this facility. ;� �•� �_ �,•a • �• yM•� •i• Mkt• Pursuant to Chapter 90A-44 of North Carolina General Statutes, and upon classification of the facility by the Certification Commission, the permittee shall employ a certified wastewater treatment plant operator in responsible charge (ORC) of the wastewater treatment facilities. Such operator must hold a certification of the grade equivalent to or greater than the classification assigned to the wastewater treatment facilities by the Certification Commission. The permittee must also employ a certified back-up operator of the appropriate type and any grade to comply with the conditions of Title 15A, Chapter 8A .0202. The ORC of the facility must visit each Class I facility at least weekly and each Class II, III, and IV facility at least daily, excluding weekends and holidays, and must properly manage and document daily operation and maintenance of the facility and must comply with all other conditions of Title 15A, Chapter 8A .0202. Once the facility is classified, the permittee shall submit a letter to the Certification Commission which designates the operator in responsible charge within thirty days after the wastewater treatment facilities are 50% complete. Part II Page 8 of 14 The permittee shall at all times properly operate and maintain all facilities and systems of treatment and control (and related appurtenances) which are installed or used by the permittee to achieve compliance with the conditions of this permit. Proper operation and maintenance also includes adequate laboratory controls and appropriate quality assurance procedures. This provision requires the operation of back-up or auxiliary facilities or similar systems which are installed by a permittee only when the operation is necessary to achieve compliance with the conditions of the permit. It shall not be a defense for a permittee in an enforcement action that it would have been necessary to halt or reduce the permitted activity in order to maintain compliance with the condition of this permit. 4. Bypassing of Treatment Facilities a. Definitions (1) 'Bypass" means the known diversion of waste streams from any portion of a treatment facility including the collection system, which is not a designed or established or operating mode for the facility. (2) "Severe property damage" means substantial physical damage to property, damage to the treatment facilities which causes them to become inoperable, or substantial and permanent loss of natural resources which can reasonably be expected to occur in the absence of a bypass. Severe property damage does not mean economic loss caused by delays in production. b. Bypass not exceeding limitations. The permittee may allow any bypass to occur which does not cause effluent limitations to be exceeded, but only if it also is for essential maintenance to assure efficient operation. These bypasses are not subject to the provisions of Paragraphs c. and d. of this section. c. Notice (1) Anticipated bypass. If the permittee knows in advance of the need for a bypass, it shall submit prior notice, if possible at least ten days before the date of the bypass; including an evaluation of the anticipated quality and affect of the bypass. (2) Unanticipated bypass. The permittee shall submit notice of an unanticipated bypass as required in Part H, E. 6. of this permit. (24 hour notice). d. Prohibition of Bypass (1) Bypass is prohibited and the Permit Issuing Authority may take enforcement action against a permittee for bypass, unless: (A) Bypass was unavoidable to prevent loss of life, personal injury or severe property damage; (B) There were no feasible alternatives to the bypass, such as the use of auxiliary treatment facilities, retention of untreated wastes or maintenance during normal Part II Page 9 of 14 periods of equipment downtime. This condition is not satisfied if adequate backup equipment should have been installed in the exercise of reasonable engineering judgment to prevent a bypass which occurred during normal periods of equipment downtime or preventive maintenance; and (C) The permittee submitted notices as required under Paragraph c. of this section. (2) The Permit Issuing Authority may approve an anticipated bypass, after considering its adverse affects, if the Permit Issuing Authority determines that it will meet the three conditions listed above in Paragraph d. (1) of this section. 5. Upsets a. Definition. "Upset " means an exceptional incident in which there is unintentional and temporary noncompliance with technology based permit effluent limitations because of factors beyond the reasonable control of the permittee. An upset does not include noncompliance to the extent caused by operational error, improperly designed treatment facilities, inadequate treatment facilities, lack of preventive maintenance, or careless or improper operation. b. Effect of an upset. An upset constitutes an affirmative defense to an action brought for noncompliance with such technology based permit effluent limitations if the requirements of paragraph c. of this condition are met. No determination made during administrative review of claims that noncompliance was caused by upset, and before an action for noncompliance, is final administrative action subject to judicial review. c. Conditions necessary for a demonstration of upset. A permittee who wishes to establish the affirmative defense of upset shall demonstrate, through properly signed, contemporaneous operating logs, or other relevant evidence that: (1) An upset occurred and that the permittee can identify the cause(s) of the upset; (2) The permittee facility was at the time being properly operated; and (3) The permittee submitted notice of the upset as required in Part II, E. 6. (b) (B) of this permit. (4) The permittee complied with any remedial measures required under Part II, B. 2. of this permit. d. Burden of proof. In any enforcement proceeding the permittee seeking to establish the occurrence of an upset has the burden of proof. Solids, sludges, filter backwash, or other pollutants removed in the course of treatment or control of wastewaters shall be utilized/disposed of in accordance with NCGS 143-215.1 and in a manner such as to prevent any pollutant from such materials from entering waters of the State or navigable waters of the United States. The permittee shall comply with all existing federal Part Il Page 10 of 14 regulations governing the disposal of sewage sludge. Upon promulgation of 40 CFR Part 503, any permit issued by the Permit Issuing Authority for the utilization/disposal of sludge may be reopened and modified, or revoked and reissued, to incorporate applicable requirements at 40 CFR Part 503. The permittee shall comply with applicable 40 CFR Part 503 Standards for the Use and Disposal of Sewage Sludge (when promulgated) within the time provided in the regulation, even if the permit is not modified to incorporate the requirement. The permittee shall notify the Permit Issuing Authority of any significant change in its, sludge use or disposal practices. The permittee is responsible for maintaining adequate safeguards as required by DEM Regulation, Title 15A, North Carolina Administrative Code, Subchapter 2H, .0124 Reliability, to prevent the discharge of untreated or inadequately treated wastes during electrical power failures either by means of alternate power sources, standby generators or retention of inadequately treated effluent. Samples collected and measurements taken, as required herein, shall be characteristic of the volume and nature of the permitted discharge. Samples collected at a frequency less than daily shall be taken on a day and time that is characteristic of the discharge over the entire period which the sample represents. All samples shall be taken at the monitoring points specified in this permit and, unless otherwise specified, before the effluent joins or is diluted by any other wastestream, body of water, or substance. Monitoring points shall not be changed without notification to and the approval of the Permit Issuing Authority. Monitoring results obtained during the previous month(s) shall be summarized for each month and reported on a monthly Discharge Monitoring Report (DMR) Form (DEM No. MR 1,1.1, 2, 3) or alternative forms approved by the Director, DEM, postmarked no later than the 30th day following the completed reporting period 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. Duplicate signed copies of these, and all other reports required herein, shall be submitted to the following address: Division of Environmental Management Water Quality Section ATTENTION: Central Files Post Office Box 29535 Raleigh, North Carolina 27626-0535 Appropriate flow measurement devices and methods consistent with accepted scientific practices shall be selected and used to ensure the accuracy and reliability of measurements of the volume of monitored discharges. The devices shall be installed, calibrated and maintained to ensure that the accuracy of the measurements are consistent with the accepted capability of that type of device. Devices selected shall be capable of measuring flows with a maximum deviation of less than + 10% from the true discharge rates throughout the range of expected Part II Page 11 of 14 discharge volumes. Once -through condenser cooling water flow which is monitored by pump logs, or pump hour meters as specified in Part I of this permit and based on the manufacturer's pump curves shall not be subject to this requirement. Test procedures for the analysis of pollutants shall conform to the EMC regulations published pursuant to NCGS 143-215.63 et. seq, the Water and Air Quality Reporting Acts, and to regulations published pursuant to Section 304(g), 33 USC 1314, of the Federal Water Pollution Control Act, as Amended, and Regulation 40 CFR 136; or in the case of sludge use or disposal, approved under 40 CFR 136, unless otherwise specified in 40 CFR 503, unless other test procedures have been specified in this permit. To meet the intent of the monitoring required by this permit, all test procedures must produce minimum detection and reporting levels that are below the permit discharge requirements and all data generated must be reported down to the minimum detection or lower reporting level of the procedure. If no approved methods are determined capable of achieving minimum detection and reporting levels below permit discharge requirements, then the most sensitive (method with the lowest possible detection and reporting level) approved method must be used. 5. Penalties for Tampering The Clean Water Act provides that any person who falsifies, tampers with, or knowingly renders inaccurate, any monitoring device or method required to be maintained under this permit shall, upon conviction, be punished by a fine of not more than $10,000 per violation, or by imprisonment for not more than two years per violation, or by both. If a conviction of a person is for a violation committed after a first conviction of such person under this paragraph, punishment is a fine of not more than $20,000 per day of violation, or by imprisonment of not more than 4 years, or both. Except for records of monitoring information required by this permit related to the permittee's sewage sludge use and disposal activities, which shall be retained for a period of at least five years (or longer as required by 40 CFR 503), the permittee shall retain records of all monitoring information, including all calibration and maintenance records and all original strip chart recordings for continuous monitoring instrumentation, copies of all reports required by this permit, for a period of at least 3 years from the date of the sample, measurement, report or application. This period may be extended by request of the Director at any time. For each measurement or sample taken pursuant to the requirements of this permit, the permittee shall record the following information: a. The date, exact place, and time of sampling or measurements; b. The individual(s) who performed the sampling or measurements; c. The date(s) analyses were performed; d. The individual(s) who performed the analyses; e. The analytical techniques or methods used; and f. The results of such analyses. Part I1 Page 12 of 14 8.
