The WTP treats groundwater from two wells screened in the Castle Hayne aquifer and pumps the finished water into the County distribution system. The current treatment techniques consist of aeration, filtration, softening, and disinfection. As part of the filtration and softening process, the filter vessels must undergo a backwash process and the softening vessels must undergo a regeneration cycle. The filtration backwash process only utilizes raw water. The softener regeneration cycle also utilizes raw water, and a salt (brine) is injected during a small portion of the cycle to restore the softener resin. The wastewater generated by the filtration backwash and softener regeneration is discharged to South Creek in the Tar-Pamlico River Basin, under NPDES Permit NC0084808. Due to failed Whole Effluent Toxicity tests (WET) prior to issuance of the 1999 permit, the County is required by Part A. (4) of the permit to submit a Discharge Alternatives Evaluation with the next permit renewal application. Appendix A contains a copy of the existing discharge permit and the fact sheet for the permit. According to permit requirements, the following options must be evaluated: 1. Connect Discharge to a Wastewater Treatment Plant (WWTP) 2. Obtain a Non-discharge Permit 3. Install Wastewater Treatment 4. Use Alternative Water Treatment Source 5. Use Alternative Water Treatment Method 6. Discharge to a Large Waterbody/Perform a Dilution Model 7. Combination of Alternatives This evaluation is to include a present worth cost analysis for all technically feasible options in accordance with Division of Water Resources guideline "Engineering Alternatives Analysis Guidance Document". 1.2 PURPOSE This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to the County to address aquatic toxicity in the plant effluent. Based upon the evaluation, please identify viable alternatives and present an implementation schedule and project timeline for the preferred alternative. The County shall submit the Discharge Alternatives Evaluation to the Division along with the submission of their next permit renewal application (due 6 months prior to permit expiration). 2.0 EXISTING CONDITIONS The Richlands Township WTP was designed to receive and treat groundwater pumped from two wells (Well #1 and Well #2). The location of the wells, the WTP, and the NPDES discharge location are shown in Figure 2.1. Information of the two wells supplying the WTP is shown in Table 2.1. Table 2.1 Richlands Township WTP Well #1 Well #2 Chloride (mg/I) 6 mg/I (11/1/2021) 10 mg/I (11/1/2021) Current Average Daily Pumped 0.0914 MGD 0.1337 MGD The average daily demand for the County varies from 0.6891 MGD to 0.8844 MGD. This information was obtained from monthly operational reports and the 2022 Local Water Supply Plans submitted to NC DEQ Water Supply Section. Appendix B contains a copy of the 2022 Local Water Supply Plan for the Beaufort County Southside water system. The current treatment train for the Richlands Township WTP is shown in Figure 2.2. The existing treatment techniques utilized at the WTP are as follows (raw to finished): • Aerator • Raw Water Reservoir • High Service Pumps • Potassium Permanganate is added • Filtration • Cation Exchange Softener • Chlorine and Ammonia are added for disinfection • Discharge of Filter Backwash and Softener Regeneration water to South Creek There are three existing filter vessels and three existing softeners at the WTP. The filters are backwashed manually according to psi gauge. The cleaning of the filter starts with a filter backwash with a flow rate of 780 gpm for approximately 10 minutes. It is then followed by a filter rinse with a flow rate of 250 gpm for approximately 5 minutes. The softeners regeneration cycles occur generally based on the amount of gallons that flow through each vessel. The regeneration cycle of the softener includes a 5-minute ion exchange backwash with a flow rate of approximately 200 gpm, a 30-minute brine injection with a flow rate of 23 gpm, a 25-minute ion exchange slow rinse, and 10-minute ion exchange fast rinse with a flow rate of approximately 250 gpm. Raw water is used for most of the filter backwash and softener regeneration cycles, but some finished water is utilized at the end of the softener regeneration. The volume generated during the filter backwash and regeneration cycle are reported on discharge monitoring reports. 2.1 SOURCE WELLS AND WTP DISCHARGE OF REGENERATION WASTE WATER EFFLUENT TO MAULS SWAMP As stated earlier, water generated during the filter backwash and regeneration cycles is currently discharged to South Creek in accordance with the NPDES permit issued. The discharge location is show in Figure 2.1. Based on discussions with the North Carolina Department of Environmental Quality (NCDEQ) and USGS, South Creek has no stream gauging station. According to NC DEQ, South Creek has a SC, NSW classification. Appendix C contains a copy of page 17 of the Tar-Pamlico River Basin hydro order that documents this classification. Thus, the existing permit does not allow any dilution factor for toxicity testing on the effluent at present. 2.2 DISCHARGE WASTEWATER CHARACTERISTICS The discharge from the filter backwash and softening regeneration process produces a wastewater that is discharged to South Creek. Data from permit Discharge Monitoring Reports (DMR) were reviewed for flowrate and water quality parameters to determine the character of the discharges. It is important to note that discharge samples are representative samples and thus reflect the filter backwash and regeneration cycle. The routine compliance sampling data indicates that the discharge has TDS, chlorides and conductivity values characteristic of a strong brine. Compliance monitoring data has shown that the WET tests from January 7, 2014 through October 8, 2019 were all fail results. Shortly after this time period, operational changes at the WTP took place that impacted the filter and softener vessels. These changes impacted the ratio of filter backwashing to softener regeneration. This in turn affected the discharge water quality. Effluent characteristics that can impact WET test results like ammonia, salinity, TDS, conductivity, etc. were reduced. Therefore, all WET test since 2000 have passed except for two (4/4/2020 & 1/4/2021). Based upon existing data from the DMRs,the following data represents current discharges from the WTP: Filter Backwash and Softener Regeneration Volume —13,000 gpd Total Dissolved Solids —7,000-8,000 mg/L Salinity "7 ppt Conductivity —4,000-21,000 umhos/cm 2.3 TOXICITY ASSESSMENT Toxicity testing is currently conducted on a composite sample of filter backwash and softener regeneration discharge water. Due to the rating of South Creek as a zero-flow stream, 90% effluent strength is used in the toxicity testing procedure. Toxicity tests are conducted using Mysidopsis bahia (mysid shrimp). The test is an Acute 24-hour Pass/Fail since it has tidal effects and is not modeled. This is based on the NPDES PERMITTING STRATEGIES FOR POTABLE WATER TREATMENT PLANTS dated October 2009. Page 8 of this document that documents Whole Effluent Toxicity Testing is included in Appendix D. It will be discussed in a later section of this document, but the discharge pipe into South Creek has an existing diffuser. This diffuser was installed during the original construction of the WTP and its accompanying discharge pipe. The attached Authorization to Construct letter dated May 31, 1996 discusses the construction of a discharge line and subaqueous diffuser. It does not appear that modeling of this discharge was conducted at the time. It is surmised that it was not conducted because WET testing was not part of the compliance monitoring at the time. 3.0 ALTERNATIVES EVALUATION 3.1 Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater treatment plant. Approval or disapproval from the plant operator should be acquired. This alternative would eliminate the surface water discharge by connection to a wastewater treatment plant (WWTP). If a discharge line to the sanitary sewer system were constructed, this line would accept the discharge effluent flows from both the filter backwash and the softener regeneration. Beaufort County does not own or operate a WWTP. The Town of Aurora owns and operates a Wastewater Treatment Plant WWTP under Permit Number NC0021521. The WWTP has a permitted capacity of 0.12 MGD and discharges into South Creek in the Tar-Pamlico River Basin. Based on limited capacity, and a review of the compliance history, addition of the discharge from the WTP to the sanitary sewer system may create further issues with the WWTP effluent. It is therefore not recommended as a viable alternative. 3.2 Obtain a Non-discharge permit: Eliminate the surface water discharge by obtaining a non-discharge permit for spray irrigation, infiltration, or subsurface disposal (on-site drain field, infiltration gallery, injection wells). This option eliminates the surface water discharge by obtaining a non-discharge permit for spray irrigation, infiltration, or subsurface disposal. In accordance with the Engineering Alternatives Analysis (EAA) Guidance Document provided by NCDEQ, waste streams from ion exchange treatment units do not have to be evaluated for land application. Discharge high in salt concentration is typically not suitable for land application, as excess salts can adversely affect plants via osmotic effect; specific ion toxicity; and soil particle dispersion, which reduces soil permeability and the water infiltration rate. Chloride levels above 350 mg/I and conductivity levels above 3,000 umhos/cm are considered severe potential irrigation problems for land application. Wastewater reuse disposal alternatives include agricultural and landscape irrigation, industrial activities, groundwater recharge, non-potable urban uses (i.e.: toilet flushing, construction water). As explained previously, the waste brine is not suitable for irrigation or landscape irrigation. State of North Carolina code 15A NCAC 02U.1101 prohibits discharge to saltwater wetlands, so this discharge alternative is not available. Additionally, the quality of the discharge would prohibit the use of the discharge for non-potable uses. The brine content does not allow the beneficial use of this waste stream for reuse application. Wastewater reuse is not a feasible alternative for disposal of this discharge. 3.3 Install wastewater treatment: Install improved wastewater treatment to enable the facility effluent to consistently pass the WET test. If this is not technically feasible or cost prohibitive, please explain and provide estimated costs. This alternative requires installation of a wastewater treatment method to enable the facility effluent to consistently pass the WET test. A candidate treatment technology for removal of chlorides is reverse osmosis (RO) technology. However, with such a high chloride content in the feed water, the RO system would need very high pressure and the percent recovery through the process would be 75%or less. Thus, RO process would produce a discharge with a concentrate still requiring discharge to a large water body. There are evaporative type systems that could evaporate the water off the brine wastewater to produce a solid (salt), but they are energy intensive and expensive. Thus, the RO treatment and/or brine evaporation option does not solve the original discharge problem and is not economically feasible. 3.4 Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest County, City, or Town or other wells) so the discharge or toxicity problem is eliminated. This alternative explores the possibility of obtaining drinking water from another source (nearest County, City, or Town or other wells) so the discharge or toxicity problem is eliminated. Based upon the 2022 Local Water Supply Plan,the Beaufort County average daily use ranged from 0.6891 to 0.8844 MGD and had a maximum day use of 1.62 MGD (September 2022). The 2022 Local Water Supply Plan also estimated the County will have a 2060 average daily demand (ADD) of 1.6809 million gallons per day (MGD). Please note that the Richlands Township WTP is one of two WTPs that supply water for the Beaufort County Southside water system. The Beaufort County Southside water system currently has a 6" emergency interconnection with the Town of Aurora water system (NC0407020). Appendix E contains a copy of the Town of Aurora water system Local Water Supply Plan for 2021. The Town of Aurora WTP has a permitted capacity of 0.2160 MGD. Due to the limited capacity of the Town of Aurora WTP it could not provide an adequate source of water to replace the Richland Township WTP demand and still provide safe potable water to the residents of the Town of Aurora. The Beaufort County Water Department utilizes groundwater sources that are in the Castle Hayne aquifer and are currently not subject to withdrawal reductions based on the Central Coastal Capacity Use Area (CCPCUA) Rules. The Division of Water Resources may not permit new groundwater sources located in deeper aquifers that are subject to the CCPCUA Rules. Since there are no public water supply wells located in the deeper aquifers in this area of Beaufort County, it is not known what raw water quality may exist or what treatment may be required. This alternative would require two new groundwater wells being installed along with the possible construction of a new water treatment plant that would have a discharge. Due to the amount of required infrastructure, this alternative is not financially feasible. 3.5 Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment methods or operational improvements that do not produce toxic wastewaters. For example, install a recycle iron/manganese filtration system with no discharge or combine discharge with WWTP or cooling water effluents. This category includes evaluating alternative and/or innovative water treatment methods or operational improvements that do not produce toxic wastewaters. In effect,this would mean eliminating the softener (and ion exchange) and using a different technology that does not produce the brine/salt discharge in the form of reverse osmosis (RO). However, these technologies produce a brine/saline discharge in the form of concentrate stream that must be disposed of. Thus, use of nanofiltration or RO would need to be combined with a large water body discharge to be applicable. This alternative does not solve the original discharge problem and is not economically feasible. 3.6 Discharge to a Larger waterbody/Perform a dilution model: Relocate the facility's discharge to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution. If applicable, perform a dilution model to receive allowance for steam dilution in WET test. In this alternative, the WTP's discharge line would be either lengthened or rerouted to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution. For any receiving body, a dilution mixing model would be needed to receive allowance for dilution in WET test and other parameters. Due to the salty nature of the discharges, the best choice for a new discharge location would be to the Pamlico River where the salinity of the discharge will not have an impact. The difference between the existing discharge and the Pamlico River is the discharge condition. South Creek (Index No. 29-28-(4)) is considered tidal saltwater not modeled and the Pamlico River is just saltwater. Appendix C contains a copy of page 17 of the Tar-Pamlico River Basin hydro order that documents these classifications. A discharge to the Pamlico River would not appear to change the WET test requirements, but would be considered a larger receiving waterbody. A new discharge force main from the WTP would be approximately 10.5 miles to the Pamlico River. Appendix F contains a map showing the route required. An extension of the existing discharge force main from South Creek to the Pamlico River would be approximately 8.5 miles. Appendix F also contains a map showing the route required. Movement of the discharge would also require a dilution model to be performed so that an allowance for stream dilution could be secured. Due to the amount of required infrastructure, this alternative is not financially feasible. 3.7 Combination of Alternatives: Employ any combination of the alternatives listed above that would result in eliminating or decreasing toxicity until a more feasible solution becomes available. Each of the alternatives stated above either do not solve the original discharge problem and/or are not financially feasible for Beaufort County. Therefore, a combination of these alternatives would also not solve the original discharge problem and/or would not be financially feasible. 3.8 Discharge Variance Beaufort County may apply to the Environmental Management Commission (EMC) for a variance to the NPDES permit discharge requirements under State Statute 143-215.3 (e). This statute reads as follows: "Variances. —Any person subject to the provisions of G.S. 143-215.1 or 143-214.1, 143- 215, or 143-215.107. The Commission may grant such variance, for fixed or indefinite periods after public hearing on due notice, or where it is found that circumstances so require, for a period not to exceed 90 days without prior hearing and notice. Prior to granting a variance here under, the Commission shall find that: (1) The discharge of waste or the emission of air contaminants occurring or proposed to occur do not endanger human health or safety; and (2) Compliance with the rules, standards, or limitations from which variance is sought cannot be achieved by application of best available technology found to be economically reasonable at the time of application for such variances, and would produce hardship without equal or greater benefits to the public, provided that such variances shall be consistent with the provision of the Federal Water Pollution Control Act as amended or the Clean air Act as amended; and provided further, that any person who would otherwise be entitled to a variance or modification under the Federal Water Pollution Control Act as amended or the Clean Air Act as amended shall also be entitled to the same variance from or modification in rules, standards, or limitations established pursuant to G.S. 143-214.1, 143-215, and 143- 215.107, respectively." If NPDES variances were to be granted for the WTPs by the DWR, the variance must be applied for, re-evaluated by DWR, and granted every five years for each NPDES permit renewal. It is not clear at this point what cost would be incurred for the variance requests for the WTP in the future as the requirements are determined on a case by case basis. 4.0 ALTERNATIVES PRESENT WORTH COSTS A present worth costs analysis was not completed because the alternatives would either not solve the original discharge problem and/or would not be financially feasible for Beaufort County. 5.0 PREFERRED ALTERNATIVE This study has been conducted to meet NPDES permit requirements to assess methods for treatment/discharge of wastewater from the WTP to avoid the toxicity impact on South Creek. The feasibility of alternative methods was presented in Section 3. The cost of the alternatives is significant and most do not solve the original discharge problem. Based on the most recent compliance data,the WET test results have been a "pass" for the last three years. The last "fail" was on 1/4/2021. This historical sampling is documented in Appendix G. Since the County has been passing the WET tests for at least three years, the preferred alternative is to continue operations and testing as is since compliance is being achieved. If in the future compliance for the WET testing is not being achieved, the County would then prefer to investigate modeling credit for the existing diffuser. Initial talks with NC DEQ Central Office staff have indicated that a meeting of the permittee, staff, and consultant should take place to discuss the viability of a dilution model as well as the modeling process. This would give NC DEQ staff an opportunity to search their files to determine if modeling took place with the initial submittal in 1996 and was just not utilized for sampling credit. 5.1 ALTERNATIVE IMPLEMENTATION It is important to note that the preferred alternative is not part of the seven (7) alternative choices that are listed on page 5 of 7 of the permit. The recommended implementation steps are as follows: 1. Continue to operate the WTP as is, collect and analyze WET test samples from the discharge per existing permit conditions, and maintain compliance. 2. If future compliance is not achieved, a meeting with NC DEQ staff to determine the process for receiving dilution credit from the existing diffuser. The County would then secure a firm to complete the modeling for the existing diffuser. 5.2 PROJECT SCHEDULE The project schedule for implementation steps 1 & 2 are dependent on the results of future WET testing. The schedule for step 1 would be current. If step 1 cannot be maintained strictly based on the WET test compliance monitoring, then a meeting will be scheduled (step 2) to start the process of modeling for dilution credit at the existing diffuser.

Concerning your comment that the close proximity of a wastewater discharge from the Town of Aurora would make instream sampling unrepresentative of the Richland WTP discharge wastewater,after discussion with the Washington Regional Office,the Division has concluded instream monitoring will remain in the permit. In regards to the question concerning instream sampling locations,please contact the Washington Regional Office to determine appropriate locations. Please note that the practical quantitation limit(PQL)for Total Copper is 2 µg/L and the PQL for Total Zinc is 10 µg/L(per the Inorganic Chemistry Branch of the Division of Water Resources Water Sciences Section) and monitoring data should be reportable down to these levels.Limits for water treatment plants are determined by evaluating DMR data submitted to the Division,along with a dilution factor(if applicable) and the maximum monthly average flow reported in the previous 3 years at the time the review is completed. Whole Effluent Toxicity test results submitted during the past three years have demonstrated that the Water Treatment Plant's effluent is showing potential for causing aquatic toxicity in the receiving stream.As a result,Beaufort County shall perform a Discharge Alternatives Evaluation as described in Section A. (3)of this permit.This evaluation is being requested to determine whether there are any economical and technologically feasible alternatives available to Beaufort County to comply with all NC Water Quality Standards.The permittee will be given approximately one permit cycle to evaluate and document possible treatment/discharge alternatives to eliminate aquatic toxicity.The evaluation shall be submitted with the permittee's next permit renewal application and will be carefully reviewed by the Division and the results will be used in the development of a compliance schedule or possible variance request for Beaufort County. If any parts,measurement frequenciessampling or sam lin requirements contained in this permit are unacceptable to you,you have the right to an adjudicatory hearing upon written request within thirty(30)days following receipt of this letter.

(2) ACUTE TOXICITY PASS/FAIL MONITORING ONLY (QUARTERLY) [15A NCAC 02B .0500 et seq.] The permittee shall conduct acute toxicity tests on a quarterly basis using protocols defined in the North Carolina Procedure Document entitled"Pass/Fail Methodology For Determining Acute Toxicity In A Single Effluent Concentration"(Revised-December 2010 or subsequent versions). The monitoring shall be performed as a Mysid Shrimp (Mysidopsis bahia)24 hour static test. The effluent concentration at which there may be at no time significant acute mortality is 90% (defined as treatment two in the procedure document).. The tests will be performed during the months of January,April,July, and October. These months signify the first month of each three month toxicity testing quarter assigned to the facility. Effluent sampling for this testing must be obtained during representative effluent discharge and shall be performed at the NPDES permitted final effluent discharge below all treatment processes. All toxicity testing results required as part of this permit condition will be entered on the Effluent Discharge Monitoring Form(MR-1)for the month in which it was performed,using the parameter code TGE3E. Additionally,DWR Form AT-2 (original)is to be sent to the following address: Attention: North Carolina Division of Water Resources Water Sciences Section/Aquatic Toxicology Branch 1621 Mail Service Center Raleigh,NC 27699-1621 Completed Aquatic Toxicity Test Forms shall be filed with the Water Sciences Section no later than 30 days after the end of the reporting period for which the report is made. Test data shall be complete and accurate and include all supporting chemical/physical measurements performed in association with the toxicity tests, as well as all dose/response data. Total residual chlorine of the effluent toxicity sample must be measured and reported if chlorine is employed for disinfection of the waste stream. Should there be no discharge of flow from the facility during a month in which toxicity monitoring is required, the permittee will complete the information located at the top of the aquatic toxicity(AT)test form indicating the facility name,permit number,pipe number, county, and the month/year of the report with the notation of"No Flow"in the comment area of the form.

Modifications to the schedule in excess of four months will be subject to public notice. A. (4) DISCHARGE ALTERNATIVES EVALUATION [15A NCAC 02H .0105] The Permittee shall assess potential alternatives to eliminate Whole Effluent Toxicity (WET)test failures. This evaluation shall assess the feasibility of all the following alternatives. 1. Connect discharge to a WWTP: Determine whether the wastewater can be discharged to a wastewater treatment plant. Approval or disapproval from the plant operator should be acquired. 2. Obtain a Non-discharge permit: Eliminate the surface water discharge by obtaining a non-discharge permit for spray irrigation, infiltration, or subsurface disposal (on-site drainfield, infiltration gallery, injection wells). 3. Install Wastewater Treatment: Install improved wastewater treatment to enable the facility effluent to consistently pass the WET test. If this is not technically feasible or cost prohibitive, please explain and provide estimated costs. 4. Use Alternative Water Treatment Source: Obtain drinking water from another source (nearest County, City, or Town or other wells) so the discharge or toxicity problem is eliminated. 5. Use Alternative Water Treatment Method: Install alternative and/or innovative water treatment methods or operational improvements that do not produce toxic wastewaters. For example, install a recycle iron/manganese filtration system with no discharge or combine discharge with WWTP or cooling water effluents. 6. Discharge to a Larger waterbody/Perform a dilution model: Relocate the facility's discharge to a larger receiving waterbody to eliminate or reduce toxic impacts to the receiving waterbody given the increased dilution.

A. (6) ELECTRONIC REPORTING OF MONITORING REPORTS [NCGS 143-215.1 (b)] Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and program reports. The final NPDES Electronic Reporting Rule was adopted and became effective on December 21, 2015. NOTE: This special condition supplements or supersedes the following sections within Part II of this permit(Standard Conditions for NPDES Permits): • Section B. (11.) Signatory Requirements • Section D. (2.) Reporting • Section D. (6.) Records Retention • Section E. (5.) Monitoring Reports Page 7 of 10 DocuSign Envelope ID:C63313B3-E17C-44C4-A808-A7C52CBEC472 Permit NC0084808 1. Reporting Requirements (Supersedes Section D. (2.)and Section E. (5.)(a)l The permittee shall report discharge monitoring data electronically using the NC DWR's Electronic Discharge Monitoring Report(eDMR)internet application. Monitoring results obtained during the previous month(s)shall be summarized for each month and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter monitoring data and submit DMRs electronically using the internet. Until such time that the state's eDMR application is compliant with EPA's Cross-Media Electronic Reporting Regulation(CROMERR), permittees will be required to submit all discharge monitoring data to the state electronically using eDMR and will be required to complete the eDMR submission by printing, signing, and submitting one signed original and a copy of the computer printed eDMR to the following address: NC DEQ/Division of Water Resources/Water Quality Permitting Section ATTENTION: Central Files 1617 Mail Service Center Raleigh,North Carolina 27699-1617 If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the facility being physically located in an area where less than 10 percent of the households have broadband access, then a temporary waiver from the NPDES electronic reporting requirements may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1, 1.1,2, 3)or alternative forms approved by the Director. Duplicate signed copies shall be submitted to the mailing address above. See "How to Request a Waiver from Electronic Reporting" section below. Regardless of the submission method,the first DMR is due on the last day of the month following the issuance of the permit or in the case of a new facility, on the last day of the month following the commencement of discharge. Starting on December 21,2020,the permittee must electronically report the following compliance monitoring data and reports,when applicable: • Sewer Overflow/Bypass Event Reports; • Pretreatment Program Annual Reports; and • Clean Water Act(CWA) Section 316(b)Annual Reports. The permittee may seek an electronic reporting waiver from the Division (see"How to Request a Waiver from Electronic Reporting"section below). 2. Electronic Submissions In accordance with 40 CFR 122.41(1)(9),the permittee must identify the initial recipient at the time of each electronic submission. The permittee should use the EPA's website resources to identify the initial recipient for the electronic submission. Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity (EPA or the state authorized by EPA to implement the NPDES program)that is the designated entity for receiving electronic NPDES data [see 40 CFR 127.2(b)]. Page 8 of 10 DocuSign Envelope ID:C63313B3-E17C-44C4-A808-A7C52CBEC472 Permit NC0084808 EPA plans to establish a website that will also link to the appropriate electronic reporting tool for each type of electronic submission and for each state. Instructions on how to access and use the appropriate electronic reporting tool will be available as well. Information on EPA's NPDES Electronic Reporting Rule is found at:Maps://www.fe t cott(dose> I2 2t21 ISffr &4inl tiat 11 Falliwkitb i#eaiergi }i 91odebaciume ittisl /1422l2 Electronic submissions must start by the dates listed in the"Reporting Requirements" section above. 3. How to Request a Waiver from Electronic Reporting The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an electronic reporting waiver,a permittee must first submit an electronic reporting waiver request to the Division. Requests for temporary electronic reporting waivers must be submitted in writing to the Division for written approval at least sixty(60)days prior to the date the facility would be required under this permit to begin submitting monitoring data and reports. The duration of a temporary waiver shall not exceed 5 years and shall thereupon expire. At such time,monitoring data and reports shall be submitted electronically to the Division unless the permittee re-applies for and is granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting waivers are not transferrable. Only permittees with an approved reporting waiver request may submit monitoring data and reports on paper to the Division for the period that the approved reporting waiver request is effective. Information on eDMR and the application for a temporary electronic reporting waiver are found on the following web page: 4. Signatory Requirements [Supplements Section B. (11.)(b) and Supersedes Section B. (11.)(d)1 All eDMRs submitted to the permit issuing authority shall be signed by a person described in Part II, Section B. (11.)(a)or by a duly authorized representative of that person as described in Part II, Section B. (11.)(b). A person, and not a position,must be delegated signatory authority for eDMR reporting purposes. For eDMR submissions,the person signing and submitting the DMR must obtain an eDMR user account and login credentials to access the eDMR system. For more information on North Carolina's eDMR system,registering for eDMR and obtaining an eDMR user account,please visit the following web page: 111ThirdidegAtCgoVitibattligdiviSiOriSiWatersnieettiteitir Certification. Any person submitting an electronic DMR using the state's eDMR system shall make the following certification [40 CFR 122.22].NO OTHER STATEMENTS OF CERTIFICATION WILL BE ACCEPTED: "I certify, under penalty of law, that this document and all attachments were prepared under my direction or supervision in accordance with a system designed to assure that qualified personnel properly gather and evaluate the information submitted. Based on my inquiry of the person or persons who manage the system, or those persons directly responsible for gathering the information, the Page 9 of 10 DocuSign Envelope ID:C63313B3-E17C-44C4-A808-A7C52CBEC472 Permit NC0084808 information submitted is, to the best of my knowledge and belief true, accurate, and complete. I am aware that there are significant penalties for submitting false information, including the possibility of fines and imprisonment for knowing violations." 5. Records Retention [Supplements Section D. (6.)] The permittee shall retain records of all Discharge Monitoring Reports, including eDMR submissions. These records or copies shall be maintained for a period of at least 3 years from the date of the report. This period may be extended by request of the Director at any time [40 CFR 122.41]. Page 10 of 10 FACT SHEET FOR EXPEDITED PERMIT RENEWALS This form must be completed by Permit Writers for all expedited permits which do not require full Fact Sheets.Expedited permits are generally simple 100%domestics(e.g.,schools,mobile home parks,etc)that can be administratively renewed with minor changes,but can include facilities with more complex issues(Special Conditions, 303(d)listed water,toxicity testing, instream monitoring,compliance concerns).

Yes(see below) Facility Overview: The Richland Township WTP operates a greensand and ion exchange WTP designed for a potable flowrate of 0.900 MGD. The facility generates backflow with an intermittent discharge. The maximum,monthly average discharge between July 2016 and June 2019 was approximately 0.084 MGD. Compliance History (July 2014 -July 2019): • No NODs,NOVs, or enforcements • Failed 12 of last 12 toxicity tests RPA: The maximum monthly average flow between July 2016 and June 2019 was approximately 0.084 MGD. • Copper—RP; apply monthly monitoring with limit • Zinc -RP; apply monthly monitoring with limit NCG59 General Permit Eligibility: • They have failed their last 12 tox tests,therefore they are not eligible by tox standards • They use IE treatment technology in addition to greensand treatment, therefore they are not eligible • Conclusion: They are not eligible for the NCG59 Changes from previous permit to draft: • Updated eDMR footnote in A(1) and language in A(6) • Updated outfall map • Added regulatory citations • Language on the Supplement to Permit Cover Sheet has been updated • Added components list on Supplement to Permit Cover Sheet • Added facility grade citation in A(1) • Changed salinity units from mg/L to ppth in A(1) • Removed temperature monitoring in A(1) as this is no longer required per 2012 WTP guidance • Flow monitoring changed to continuous in A(1)per 2012 WTP guidance o Maximum monthly average> 50,000 gpd • Added instream monitoring for salinity, conductivity,pH, and DO in A(1)per 2009 WTP guidance o Previous factsheets and permits do not show that monitoring was ever included • Effluent sampling for conductivity and salinity changed to composite in A(1)per 2009 WTP strategy • Limits added for copper and zinc and monitoring increased to monthly in A(1)per RPA, and compliance schedule added as A(3) • Ammonia nitrogen monitoring increased from quarterly to monthly in A(1)per 2009 WTP strategy and 2012 WTP guidance o Frequency was mistakenly reduced in previous renewal • TN sample type changed from calculated to composite in A(1)per 2009 WTP strategy • Updated footnotes in A(1) • Updated toxicity language in A(2) • Added discharge alternatives analysis as new A(4)to address toxicity failures Changes from draft to final: • Instream pH monitoring separated from effluent—mistakenly kept in the same line Comments received on draft permit: • Robert Tankard (WaRO,via email 8/21/19): We have no comments. Looks good. • Hanna Headrick(Aquatic tox,via email 8/23/19): Second page of cover letter— Text references A (3.) for Discharge Alternatives Evaluation,but this is found in A(4.) o DWR response: The cover letter will be correct when the final goes out. • Eric Jennings (Permittee representative; via phone and email 9/20/19): o Concerns about instream monitoring because the Town of Aurora discharge is only 1/4 mile away, so doesn't think that instream sampling would be representative of what they put out—instream sampling was removed in the previous permit for this reason • DWR response: This will be reviewed and instream sampling may potentially be removed. o Asked where instream sampling would need to be taken, and if it could be shoreline or if it would have to be in the stream(the pipe is out in the middle of the river) • DWR response: It may be able to be taken from the shoreline,but would have to review the location and determine that is appropriate. o Via email: Upon review of the draft NPDES permit NC0084808 for Richland Township WTP, it has come to our attention that requirements to monitor salinity, conductivity,pH, and DO upstream and downstream of the outfall have been added. These new monitoring requirements pose a concern to us. The outfall for this permit is located in close proximity to the town of Aurora's wastewater discharge point. We feel that any samples taken upstream or downstream of our outfall will not be representative of our discharge water. Please consider our concerns before issuing the final permit. • DWR response: After discussion with the Washington Regional Office, instream monitoring will remain in the permit. WaRO does not feel that the nearby dischargers will affect the instream monitoring of the Richland WTP.

Whole Effluent Toxicity Testing Membrane,ion exchange,and conventional WTPs should be required to conduct quarterly WET tests for monitoring purposes. Eventually,the Division may choose to use this data to develop additional policy. The type of WET test conducted will vary depending on receiving stream characteristics. In addition,the level of available dilution and tidal effects will determine whether the facility should perform an acute or chronic test,while the type of water(freshwater or saltwater)will determine which organism should be used. Table 1 summarizes WET-testing requirements. Appendix A includes sample WET language. Crreensand filter systems will not be required to monitor whole effluent toxicity.
