The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant mortality to Ceriodaphnia dubia at an effluent concentration of 1.1%. The permit holder shall perform at a minimum, quarterly monitoring using test procedures outlined in the “North Carolina Ceriodaphttia Chronic Effluent Bioassay Procedure,” Revised December 2010, or subsequent versions or “North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure” (Revised- December 2010) or subsequent versions. The tests will be during the months of January, April, July and October. These months signify the first month of each three-month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. If the test procedure performed as the first test of any single quarter results in a failure or ChV below the permit limit, then multiple-concentration testing shall be performed at a minimum, in each of the two following months as described in “North Carolina Phase H Chronic Whole Effluent Toxicity Test Procedure” (Revised-December 2010) or subsequent versions. Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period for which the report is made. U: Upstream, at 308 Rollingwood Road. D: Downstream, at 1090 Rockfish Lane in Weldon. The permittee may discontinue influent, effluent and/or stream sampling at such times when adverse stream flows or extreme weather conditions pose a substantial risk of injury or death to persons collecting samples. On such days, written justification for sample discontinuance shall be specified in that month’s discharge monitoring report (DMR). Sampling and monitoring shall resume at the first safe opportunity. Monthly Average effluent CBOD5 and TSS concentrations shall not exceed 15% of respective influent value (i.e., 85% removal is required). The Division shall consider all effluent TRC values reported below 50 pg/I to be in compliance with this permit. The permittee shall continue to record and submit all values reported by a North Carolina certified laboratory even if these values fall below 50 pg/l. Chronic Toxicity {Ceriodaphnia') at 1.1%; January, April, July and October [see A (2)]. Variable Sampling - Upstream/Downstream samples shall be collected weekly during June, July, August, and September; and 2/month during the remaining months of the year. The Permittee shall sample instream hardness, upstream of the facility’s discharge. The sample shall be representative of the hardness in the receiving stream. Effluent hardness sampling should be performed in conjunction with testing for hardness dependent metals (cadmium, copper, lead, nickel, silver, and zinc). The permittee shall perform three effluent pollutant scans during the term of this permit [see A (3)]. North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh, NC 27699-1621 All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form (MR-1) for the months in which tests were performed, using the parameter code TGP3B for the pass/fail results and THP3B for the Chronic Vjalue. Additionally, DWR Form AT-3 (original) is to be sent to the following address: NC0024201 Page 5 of 10 Test data shall be complete, accurate, include all supporting chemical/physical measurements and all concentration/response data, and be certified by laboratory supervisor and ORC or approved designate signature. 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 Water Sciences Section at the address cited above. Should the permittee fail to monitor during a month in which toxicity monitoring is required, monitoring will be required during the following month. Assessment of toxicity compliance is based on the toxicity testing quarter, which is the three month time interval that begins on the first day of the month in which toxicity testing is required by this permit and continues until the final day of the third month. Should any test data from this monitoring requirement or tests performed by the North Carolina Division of Water Resources indicate potential impacts to the receiving stream, this permit may be re-opened and modified to include alternate monitoring requirements or limits. NOTE: Failure to achieve test conditions as specified in the cited document, such as minimum control organism survival, minimum control organism reproduction, and appropriate environmental controls, shall constitute an invalid test and will require immediate follow-up testing to be completed no later than the last day of the month following the month of the initial monitoring.

Section A. Definitions Version 11/09/2011.1 PART II STANDARD CONDITIONS FOR NPDES PERMITS NPDES Permit Standard Conditions Page 1 of 18 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/Wcck Samples arc 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 (JSC 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 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 penod 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-casc 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 scries 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 11/09/2011.1 NP 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. > Pennittees 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; sec 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 Waste water 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 instrcam samples). Section B. General Conditions 1. a. b. c. Version 11/09/2011.1 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 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 noncompliancc 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. Duty to Comply The Permittee must comply with all conditions of this permit.

The Interceptor begins adjacent to 1100 Zoo Road. There is one primary basin pump station along the route served by the interceptor whose pipe sizes range from 12" to 30". The system has six sewer lift stations. Three stations are in the Gaston basin. HWY 46 Pump Station serves a Northampton County School, Old Emporia Road Pump Station serves the Chowan Housing Projects and the Hwy 48 Pump Station pumps all flows from Gaston and Northampton County via an 8" force main suspended from the NC HWY 48 Bridge spanning the Roanoke River to the Roanoke River Interceptor. The remaining three pump stations are located within Roanoke Rapids basins and serve residential and some light commercial customers. Two of the stations, Belmont and Poplar Springs, discharge to the Roanoke River Interceptor while the Greenbriar Pump Station discharges to the Chockoyotte Creek Interceptor. Treatment processes at the wastewater plant include grit and rag removal. This is followed by primary clarification, trickling filter biological secondary treatment, activated solids treatment, secondary clarification, final effluent chlorination/de- chlorination processes, and final pH adjustment. F. Description of WWTP: The wastewater treatment plant is rated at 8.34 million gallons per day (MGD). Peak flow is rated at 12.5 MGD. The Roanoke River Interceptor collects wastewater from basins located on the north side of the Sanitary District. The Gaston basin and Northampton County are also served by this interceptor. The Interceptor begins just west of 100 Gaston Road (NC HWY 48) in Roanoke Rapids. There are 3 primary basin pump stations and 2 secondary pump stations served by the interceptor whose pipe sizes range from 18" to 30". During these processes solids are removed from two locations. Primary clarification removes settleable solids from incoming wastewater to an anaerobic digestion unit. Here the solids, in the absence of oxygen, receive pH adjustment, mixing, and heating to produce a stabilized material. Once the solids are stable, excess water is decanted and returned to the plant for further treatment. The stabilized, thickened solids are treated with lime for odor control then removed to a holding tank to await land application. II.Performance: 1. C.S: Page 3 Roanoke Rapids Sanitary District 2019 Annual Performance Report The District contracted with USDA wildlife services for outfall cutting from Chockoyotte Creek located adjacent to its interceptor. This ongoing work improved access to the interceptor and helped minimize flooding of manholes along the easement. Secondary clarification removes solids from the activated solids process. Here, solids in the presence of oxygen, pH control, and mixing, accumulate in excess. They are removed, chemically stabilized, and added to a holding facility. All stabilized solids are analyzed and land applied according to their nutrient value, ceiling and accumulative requirements. The District also contracted with Freese and Nichols & Hydro Structures to install flow meters in five locations around Roanoke Rapids. Hydro Structures also did a manhole inspections condition assessment on Manhole K-248 in Basin K and pipe condition assessments throughout Basin K. There are two pumping stations in the wastewater plant distributing wastewater into and through the plant. They are the Influent Pump Station and the Trickling Filter Effluent Pump Station. The Influent Pump Station has the capacity to pump 20 MGD and the Trickling Filter Effluent Pump Station 27 MGD. In conjunction with these two pump stations there is the Emergency Flood Pump Station with a capacity of 21 MGD to remove treated effluent from the plant during high river stages which prevent normal gravity flow discharge. Also, a storm water pump station has been installed. This station intercepts site runoff, an unnecessary treatment load and potential site flooding condition, and removes it before entry to the plant. It has the capacity to pump 11.5 MGD. Numerous other pumps and mixers are located throughout the plant for process control. The performance of the system in 2019 was very good. There were no permit violations or monitoring and reporting violations. The District's Fat, Oil, and Grease (FOG) Program performed 43 inspections of area restaurants and food preparation facilities (FSE). There were no notices of violation. All FSE were advised to continue following "Best Management Practices" and maintain maintenance records. The District FOG program sent out billing inserts on FOG information throughout the year continuing our public education program. There were no Sanitary Sewer Overflows (SSO) out of eight total SSOs during the period attributed to FOG in 2019. 2. WWTP: PARAMETER Page 4 Roanoke Rapids Sanitary District 2019 Annual Performance Report During 2019, there was one plant bypass of treatment units in which 35,343 gallons of Wastewater with some biological treatment was bypassed to the Roanoke River. There were two times during the year when flows were increased due to heavy rains. During these times, flow was equalized to the equalization basins to lower peak flows through the plant. Throughout 2019,1,706,811 gallons of wastewater was equalized and later returned to the plant for treatment. The efforts to repair the collection system and reduce Inflow and Infiltration from prior years continued in 2019. This work has led to lower peak flows and reduced the number of bypasses from the plant as illustrated in the following table: The following table illustrates the treatment performance of the wastewater plant and its ability to meet and exceed the NPDES permit requirements: The Wastewater Treatment Plant relies on anaerobic digesters for primary sludge stabilization. In 2019, the original sludge heater for digester number 1 that was installed in 1965, was replaced with new heater. The new heater is safer and more efficient. Also in 2019, the parts to update the heater for digester number 3 were ordered to make both heaters alike. The work on heater number 2 should be completed in early 2020. Digester number 2 was cleaned out and inspected in ______________Year Max Day (MGD) Avg.

The Interceptor begins adjacent to 1100 Zoo Road. There is one primary basin pump station along the route served by the interceptor whose pipe sizes range from 12" to 30". The system has six sewer lift stations. Three stations are in the Gaston basin. HWY 46 Pump Station serves a Northampton County School, Old Emporia Road Pump Station serves the Chowan Housing Projects and the Hwy 48 Pump Station pumps all flows from Gaston and Northampton County via an 8" force main suspended from the NC HWY 48 Bridge spanning the Roanoke River to the Roanoke River Interceptor. The remaining three pump stations are located within Roanoke Rapids basins and serve residential and some light commercial customers. Two of the stations, Belmont and Poplar Springs, discharge to the Roanoke River Interceptor while the Greenbriar Pump Station discharges to the Chockoyotte Creek Interceptor. F. Description of WWTP: The wastewater treatment plant is rated at 8.34 million gallons per day (MGD). Peak flow is rated at 12.5 MGD. The Roanoke River Interceptor collects wastewater from basins located on the north side of the Sanitary District. The Gaston basin and Northampton County are also served by this interceptor. The Interceptor begins just west of 100 Gaston Road (NC HWY 48) in Roanoke Rapids. There are 3 primary basin pump stations and 2 secondary pump stations served by the interceptor whose pipe sizes range from 18" to 30". Treatment processes at the wastewater plant include grit and rag removal. This is followed by primary clarification, trickling filter biological secondary treatment, activated solids treatment, secondary clarification, final effluent chlorination/de- chlorination processes, and final pH adjustment. During these processes solids are removed from two locations. Primary clarification removes settleable solids from incoming wastewater to an anaerobic digestion unit. Here the solids, in the absence of oxygen, receive pH adjustment, mixing, and heating to produce a stabilized material. Once the solids are stable, excess water is decanted and returned to the plant for further treatment. The stabilized, thickened solids are treated with lime for odor control then removed to a holding tank to await land application. II.Performance: 1. C.S: Page 3 Roanoke Rapids Sanitary District 2019 Annual Performance Report The District contracted with USDA wildlife services for outfall cutting from Chockoyotte Creek located adjacent to its interceptor. This ongoing work improved access to the interceptor and helped minimize flooding of manholes along the easement. Secondary clarification removes solids from the activated solids process. Here, solids in the presence of oxygen, pH control, and mixing, accumulate in excess. They are removed, chemically stabilized, and added to a holding facility. All stabilized solids are analyzed and land applied according to their nutrient value, ceiling and accumulative requirements. There are two pumping stations in the wastewater plant distributing wastewater into and through the plant. They are the Influent Pump Station and the Trickling Filter Effluent Pump Station. The Influent Pump Station has the capacity to pump 20 MGD and the Trickling Filter Effluent Pump Station 27 MGD. In conjunction with these two pump stations there is the Emergency Flood Pump Station with a capacity of 21 MGD to remove treated effluent from the plant during high river stages which prevent normal gravity flow discharge. Also, a storm water pump station has been installed. This station intercepts site runoff, an unnecessary treatment load and potential site flooding condition, and removes it before entry to the plant. It has the capacity to pump 11.5 MGD. Numerous other pumps and mixers are located throughout the plant for process control. The District also contracted with Freese and Nichols & Hydro Structures to install flow meters in five locations around Roanoke Rapids. Hydro Structures also did a manhole inspections condition assessment on Manhole K-248 in Basin K and pipe condition assessments throughout Basin K. The performance of the system in 2019 was very good. There were no permit violations or monitoring and reporting violations. The District's Fat, Oil, and Grease (FOG) Program performed 43 inspections of area restaurants and food preparation facilities (FSE). There were no notices of violation. All FSE were advised to continue following "Best Management Practices" and maintain maintenance records. The District FOG program sent out billing inserts on FOG information throughout the year continuing our public education program. There were no Sanitary Sewer Overflows (SSO) out of eight total SSOs during the period attributed to FOG in 2019. 2. WWTP: PARAMETER Page 4 Roanoke Rapids Sanitary District 2019 Annual Performance Report Over the course of 2019, the Roanoke River Wastewater Plant operated very efficiently. There were no permit violations or monitoring and reporting violations. The plant flows ranged from a daily maximum of 11.4 Million Gallons per Day(MGD) to a minimum of 1.8 MGD. The average daily flow was 3.2 MGD. The plant treated 1,317,800,000 gallons of wastewater throughout the year; which was discharged to the Roanoke River. During 2019, there was one plant bypass of treatment units in which 35,343 gallons of Wastewater with some biological treatment was bypassed to the Roanoke River. There were two times during the year when flows were increased due to heavy rains. During these times, flow was equalized to the equalization basins to lower peak flows through the plant. Throughout 2019,1,706,811 gallons of wastewater was equalized and later returned to the plant for treatment. The efforts to repair the collection system and reduce Inflow and Infiltration from prior years continued in 2019. This work has led to lower peak flows and reduced the number of bypasses from the plant as illustrated in the following table: The following table illustrates the treatment performance of the wastewater plant and its ability to meet and exceed the NPDES permit requirements: The Wastewater Treatment Plant relies on anaerobic digesters for primary sludge stabilization. In 2019, the original sludge heater for digester number 1 that was installed in 1965, was replaced with new heater. The new heater is safer and more efficient. Also in 2019, the parts to update the heater for digester number 3 were ordered to make both heaters alike. The work on heater number 2 should be completed in early 2020.

In 2019, the original sludge heater for digester number 1 that was installed in 1965, was replaced with new heater. The new heater is safer and more efficient. Also in 2019, the parts to update the heater for digester number 3 were ordered to make both heaters alike. The work on heater number 2 should be completed in early 2020. Digester number 2 was cleaned out and inspected in A. 2. WWTP: N/A D. Bypass of Treatment Facility 1. C.S.: N/A Page 5 Roanoke Rapids Sanitary District 2019 Annual Performance Report 2019 along with having the steel floating top removed, blasted, and recoated to preserve and extend its useful life. Furthermore, a new waste gas burner was ordered and received that will automatically control the methane gas system pressure for the digester heaters. This will prevent the wasting of methane gas and the release of unburned methane gas into the atmosphere. The new burner will be installed in January of 2020. There are 1985.46 acres of applicable land currently permitted through the District's Land Application Permit. During 2019 there were 2,609,393 gallons, or 559.29 dry tons of biosolids applied to 209.53 acres. There were no permit violations for the land application program in 2019. C. 2019 Sanitary Sewer Overflows 1. C.S.: There were 8 reportable SSO's in 2019. 1. Manhole 138 at 1st & Franklin St., 1,200 Gal. 2. Manhole 11 2nd & Franklin St., 1,800 Gal. 3.

Page 6 Roanoke Rapids Sanitary District 2019 Annual Performance Report 1. C.S.: Along with the wildlife control, FOG program and outfall clearing discussed above, RRSD continues to perform preventative sewer backup maintenance by cleaning with Jetter and Root Cutter; which is attached to the Jetter hose, followed by Closed Circuit TV (CCTV) camera to inspect the lines after cleaning. The District also uses its Vac-con Truck, which cleans the line more effectively and proves to be more reliable than the old unit. The District also continues to use the Rausch CCTV van purchased in 2018 extensively. The District contracted with Freese & Nichols and Hydro Structures to install flow meters and perform condition assessment of District assets. Hydro-Structures performed a manhole inspection of Manhole K-248 in Basin K and pipe condition assessments throughout Basin K. The flow meters were used to calculate the estimated inflow and infiltration during rain events. The locations of the flow meters are District employees completed 14 total new replacement taps in 2019. Eleven of which were 4" replacement taps throughout the district service area. District employees utilized the District's excavator mounted flail mower in conjunction with NC Wildlife Solutions LLC to cut and clear 16.88 miles of interceptor right-of-way's and cross-country lines in 2019. District employees cleaned 23.30 miles of sewer lines and CCTV'd all suspect problem areas. District employees completed three Sanitary Sewer Point Repairs in 2019. The locations were 1304 Roanoke Ave, 1505 Murphey St, and 524 NC Hwy 125. • Smith Church Rd.
