None noted in the application New expiration date: i May 31, 2028 FACILITY OVERVIEW: This facility is 100% domestic waste and treats flow from an area serving a population of 1,928 people. The facility has a permitted and as -built flow of 0.33 MGD. The treatment system includes the following wastewater treatment components: • Static screen • Surge basin • Influent flow splitter box • Two extended aeration treatment plants in parallel • Contact chamber with sodium hypochlorite disinfection • Dechlorination (sodium bisulfate) • Effluent flow meter • Three aerated sludge digesters • Standby power The town received an Authorization to Construct in 2016 for extensive upgrades to their system. There is no indication that any of the changes have been made at this point. The Town also holds Collection System permit WQCS00216 and Water Treatment Plant Permit - NC0086797. APPLICATION The application (December 6, 2022) does not indicate any changes in the facility or treatment since the last renewal of the permit in 2018. The treatment system is owned and operated by the Town of River Bend. The annual average daily flow is indicated as 0.103 MGD over the last two years and 0.111 MGD at the time of the renewal application. The facility is currently operating well below its permitted capacity of 0.33 MGD. Some maximum daily flows are noted as being near the permitted flow, but no monthly average values are above 0.16 MGD. The application notes the facility has average daily I/I of 2,500 GPD and indicates efforts to identify sources of inflow using smoke testing and TV evaluation of the system. The application notes the system as having primary and secondary treatment that achieves 95% BOD and TSS removal. INSPECTION The most recent inspection occurred on February 25, 2021. Regional staff found no significant issues with the facility. The report did note the need for repair to a skimmer/rake on the clarifier. The Town's Collection System (WQCS00216) was last inspected November 18, 2020, and indicated the system was in compliance.

REVIEW OF PERMIT LIMITS: Flow - Over the permit cycle the facility has shown average flow of around 0.11 MGD. There were no monthly average exceedances over the permit term and the facility is operating well below the permitted and as -built flow of 0.33 MGD. BOD I TSS- The facility had one (1) weekly average and one (1) monthly average BOD limit violation over the permit term and has shown average monthly BOD removal of 98.5%. For TSS the facility had one (1) weekly average limit violation. The treatment system has shown average monthly TSS removal of 98.1%. Town of River Bend WWTP Fact Sheet NPDES Renewal 2023 - September 13, 2023 Page 2 Enterococci - Data results for Enterococci did not show any exceedances. The limits to Enterococci are set based on a July 2006 implementation memo. Dissolved Oxygen - Data for dissolved oxygen does not appear to show any impacts from the discharge. Ammonia (NH3I- The facility has shown no violations for ammonia limits. Note that the NH3-N limits in the permit were established with previous modelling efforts. The waste load allocation spreadsheet shows numbers that are a little higher, but this is overridden by the results of the previous modelling efforts in previous WLA. Total Residual Chlorine (TRCI - The permittee had two hundred sixty-one (261) TRC values over the 13 µg/L compliance level. None of these values was above the 50 µg/L compliance level. As noted with Ammonia above, the TRC limits were previously established in modelling efforts that are more stringent and utilized rather than the results of the WLA spreadsheet. Nutrients Total Nitrogen load numbers over the permit cycle included a maximum annual load of 6,451 lbs. and an average annual load of 5,097. The allocation for the facility is 7,482 lbs per year so the facility is below its annual allocation for TN. The current permit includes a footnote that indicates compliance with the total nitrogen annual load is determined in accordance with the special condition on annual limits for total nitrogen. This permittee is not subject to TN load limits as the discharge is < 0.5 MGD. This footnote and the special condition have been removed from the permit. Total Phosphorous (TP) levels have been reported at levels (average of 4.3 mg/L) that could be of concern if the facility is ever required to meet TP limits. COMPLIANCE: The facility has not had a documented enforcement action with penalties since 2013. Over the permit cycle their was one (1) NOD issued for BOD violations. The facility had regular TRC values over their limit (261 exceedances) but none of the values was above the 50 µg/L compliance level. FILE HISTORY REVIEW SUMMARY • BIMS indicates permit was originally issued May 24, 1982 but some other electronic files indicate the permit was in place earlier. There were three pdf files on the shared drive that contained mainly Waste Load Allocation (WLA) information from 1976 through 1994. There were no permit documents in these files. • The 1976 WLA was for a flow of 0.1 MGD with summer 7Q10 of 4.2 cfs and set limits for BOD and TSS at 30 mg/L and Fecal at 200 #/100ml. • May 6, 1981 - WLA added pH of 6 to 9. • August 16, 1983 WLA set the same limits for a flow of 0.17MGD for Carolina Water Service as the permittee. • September 10, 1984 - WLA set the same limits for flows of 0.27and 0.37 MGD. • April 21, 1988 - WLA completed for 0.37MGD flow. The WLA utilized 7Q10S - 4.2; 7Q10W -10 and avg flow - 529 cfs. Flow BOD5 DO TSS Fecal pH MGD (m /L) (m /L) (m /L) (#/100 ml) (std units) 0.37 30 5 30 200-summer 6.8 - 8.5 1000 - winter The WLA also included instream monitoring for Temperature, DO, pH and Salinity. The WLA also required the permittee to install a diffuser for the discharge point working with the WaRO to identify the location. • September 26, 1988 - WLA completed for flows of 0.17 and 0.37 MGD. This WLA had the same limits with the exception of the addition of a 2 mg/L TP limit. Town of River Bend WWTP Fact Sheet NPDES Renewal 2023 — September 13, 2023 Page 3 • November 6, 1989 - The Division issued a memo to add to the permit file that removed the TP limit and from the recently issued permit because the expansion request had been received by the Division prior to the EMC adoption of Neuse rules that impacted the TP decision. This memo also removed the increase of the facility's treatment system classification to Class III. • July 19, 1994 - WLA Flow BODS NH3-N DO TSS Fecal pH TRC TN TP Temp (MGD) (mg/L) (mg/L) (mg/L) (mg/L) (#/100 (std (µg/L) (mg/L) (mg/L) MA / WA MA/WA DM MA / WA MI) units) DM MA WA 0.33 30 45 6.7/Monitor 5 30 45 200 / 400 6-9 Monitor Monitor Monitor Monitor 5 (s) MA 0.37 10(w) 2 (s) MA 5 30 MA 200 MA 6-9 28 Monitor 2 MA Monitor 4(w) MA MA This WLA also included recommendations from the WaRO for vertical instream monitoring which the region had required for similar facilities in their region. 1996 - Permit ownership changed in this timeframe to the Town of River Bend. The hard copy documents reviewed included Authorizations to Construct (ATC) back to 1998 along with permits beginning with the 2003 permit renewal: • October 2,1998 Authorization to Construct (ATC) for the installation of an equalization tank, radio control telemetry system and associated materials. • December 10, 1999 - Letter from permittee indicating previous ATC construction had been abandoned when bids came in high and funding not available. • June 18, 2002 ATC for filter press assembly with vacuum pump; structure to protect filter press assembly; pump tank with dual pumps and all associated materials, etc. • March 12, 2004 Speculative Limits Letter from Division for a flow of 0.8 MGD - Effluent Characteristics Flow - 0.80 MGD Effluent Limits Monthly Avg Weekly Avg Daily Max BOD5, 20°C - Summer m L 5.0 7.5 BODS, 20°C - Winter m L 10.0 15.0 NH3 as N - Summer m L 2.0 6.0 NH3 as N - Winter m L 4.0 12.0 TSS m L 30 45 TRC µ L 28 Fecal Coliform # 100 rnQ 200 400 Total P m L) 1.0 Total N lbs ear) 7,482 The speculative limits letter also noted that the Division was beginning implementation of water quality standards for enterococci and limits could be added to the permit. The town had requested spec limits for 1 MGD as well but the Division did not give limits for this flow because the concentration based nitrogen limit at this flow would be beyond the limits of technology. June 13, 2005 - ATC for installation of a liquid sodium bisulfate dechlorination system. September 27, 2005 - Engineer's Certification of construction of dechlorination system. December 22, 2003 - Permit Renewal - This permit was renewed with the permitted flow of 0.33MGD and no additional phase flow levels (appears that the 0.37 MGD flow level was removed at the request of the Town in the 2000 permit renewal).

The permit also included the special condition for the calculation of Total Nitrogen loads. The permit added the weekly average limit for NH3-N. Town of River Bend WWTP Fact Sheet NPDES Renewal 2023 — September 13, 2023 Page 4 August 6, 2008 - Permit Renewal - This renewal removed fecal limits and replaced them with enterococci limits of 35/100ml (monthly average) and 276/100ml (weekly average) to meet new bacteria standards for marine waters. The renewal also changed the TRC limit to 13µg/L to comply with acute criteria for saltwater and also added the TRC compliance level of 50 µg/L. Special condition for Total Nitrogen Allocations was also added with an allocation amount at the estuary and discharge of 7,482 lbs/year.

December 5, 2013 - Permit Renewal - This renewal added the electronic reporting requirements to the permit including the parameter codes, etc. It also added a requirement (through a special condition) for an annual effluent mercury analysis. January 15, 2016 - ATC for extensive modifications to the treatment system (see ATC document in Laserfiche for details). This authorization did not increase the design or permitted capacity of the system. October 11, 2018 - Permit Renewal - No major changes other that map updates and addition to regulatory citations. PROPOSED PERMIT CHANGES: • Updated eDMR requirements to be consistent with final EPA rule. • Added or updated regulatory citations throughout permit as needed, including changes to reflect recently updated rule citations for Neuse requirements. • Footnote 5 which indicated TN annual load compliance would be determined in accordance with the Annual Limits for Total Nitrogen section has been removed since this facility is not subject to TN load limits at this time. Section A.(3.) has also been removed. • Added Special Condition for Nutrient Re -opener in section A.(5.). • Permit map information updated.

Looking through my records it does not appear that I forwarded the attached draft permit to the Town when it went to public notice in Late September. The notice period is completed. We did not get any public comments so we can move forward with issuance of the permit. However, I wanted to send the draft that I failed to send before and let the Town take a look at it for any comments you may have before I move forward to get the final permit signed. Please take a look at the attached draft and let me know if you have any comments as soon as you can. There are no major changes to the permit, but the updates are outlined in the cover letter.

Bennett, Bradley From: Deuterman, Sydney Sent: Friday, September 15, 2023 3:10 PM To: Bennett, Bradley Subject: RE: Draft Permit for Review - Town of River Bend WWTP - NC0030406 Hey Bradley, Here are my comments for this draft! Permit: - Footnotes in the eff. table need to be re -numbered. Above the table, "monitoring" is labelled with footnote 7 and Mercury is labelled with footnote 6. - Might be just a personal thing, but maybe you should label NO2+NO3 on the table with footnote 3 as well, since TN has it? - Monthly and Annual eDMR codes for TN Load need to be swapped - eDMR code for Mercury is incorrect. Should be "[COMER]". I actually couldn't find any parameter in the BIMS code list with 71900, so must've been an old code that didn't get corrected in the last renewal. I'd also update the monitoring frequency to say "1 / Permit Cycle" instead of "1/5 years" - I've noticed this on my own draft permit that I'm currently working on —the condition for nutrient allocations has a "T" before 15A in the rule citation. Any idea why? Every time I pull up the rule (shhh, don't tell John), I only see it begin with 15A. FartshPat - In the table at the beginning, UGSS Topo just has a "/" in it. Not sure if you meant to leave it blank or not. - Small typo in your list of permit changes —"TN load hits" instead of limits Hope you have a great weekend!

Mr. Bennett, Transmittal of documents electronically is acceptable to me. Due to lack of funding we never began construction on any of those improvements. As far as Permit contacts the only changes I see that need to be made are: 1) Permit contact person, Tom Datt should be deleted, and my name added. 2) Persons with signatory authority: Jim Freeman should be deleted, and Charles D Jackson added.

I just wanted to touch base on a few items and to get you my contact information. Please see the items mentioned below for your attention. Information on 2016 Authorization to Construct: In January of 2016 the Town received an authorization to construct from DWR for a large number of improvements to the treatment system. We have not received an Engineer's Certification for any of these items and wanted to check with you to see if any of those construction items had been put in place? If so, please provide me with information on what has been completed. Update to Permit Contacts: I have attached a pdf file with the current contact information that we have in our system for the permit. Could you please review this information and let me know if there are any changes/deletions/additions that need to be made. You can either email me back a description of the changes or you can mark up a hard copy of the document and scan it and return it to me at this email. Electronic Submittal of Permit Documents: In order to provide more convenience, control, and security to our permittees and assist them in processing their transactions, The Division of Water Resources is currently transitioning towards electronic correspondence.

I had a quick question about this one. I'm assuming this one should go to you, but feel free to forward the question on if there is someone else in the region that you think could address this. In 2016 River Bend got an ATC for a number of upgrades. I don't see an engineer's certification for any of this and was just wondering if they ever made any of the upgrades they were approved for? Do you know if they did any of this and if so, I may want your input to make any needed modifications to the treatment system components list in the permit.
