None noted in the application New expiration date: I May 31, 2028 FACILITY OVERVIEW: The facilities are public water treatment plants that are 100% industrial waste and treat well water to produce finished potable water for portions of Craven County. Water Treatment Plant 1 (WTP#1) has a discharge of treated backwash/rinse wastewater from Sand Filtration units through Outfall 001. This water treatment plant currently has a design potable flow rate of 0.6 MGD and a maximum, monthly average wastewater discharge of 0.014 MGD. This facility is located at 52 Shoreline Dr. and water and wastewater treatment consist of: • Raw well water caustic addition systems • Potable water chlorination system • Raw well air injection systems • Wastewater dechlorination system • One (1) 8 ft. diameter sand filter tank • 5,000-gallon backwash/rinse wastewater • One (1) 10 ft. diameter sand filter tank settling basin with pump • Potable water ortho phosphate addition system 9 Effluent meter Water Treatment Plant 2 (WTP#2) has a discharge of treated backwash/rinse wastewater from Sand Filtration units through Outfall 002. This water treatment plant currently has a design potable flow rate of 0.35 MGD and a maximum, monthly average wastewater discharge of 0.011 MGD. This facility is located at 27 Shoreline Dr. and water and wastewater treatment consist of: • Raw well water caustic addition system • Raw well air injection system • Two (2) 4.5 ft. diameter sand filter tanks • Two (2) 6 ft. diameter sand filter tanks • Potable water ortho phosphate addition system chemical additives: — Sodium hydroxide [pH adjustment] — polyphosphate [scale inhibitor] — chlorine gas [disinfection] — Sodium bisulfite [dichlorination] • Potable water chlorination system • Wastewater dechlorination system • 5,000-gallon backwash/rinse wastewater settling basin with pump • Effluent meter Raw Water Treatment Process: (from application, historical documents and 2020 System Evaluation on Town website) Two (2) groundwater wells supply WTP#1 and a third well supplies WTP#2. WTP#1 has two (2) sand filter units and WT#2 has four (4) sand filter units. Sand filters are anthracite over Birm sand filter media. Raw water is injected with Caustic Soda (sodium hydroxide) for pH adjustment and compressed air (oxygen) to oxidize soluble iron and manganese. Water then flows through the sand filters, is chlorinated, treated with phosphate corrosion inhibitor and then goes to the distribution system. Wastewater and Treatment Process: (from application, historical documents and 2020 System Evaluation on Town website) Wastewater generated from the system comes from backwash water and rinse water. Finished water is used for backwash and rinse water for each WTP. Each WTP has its own treatment system that includes liquid dichlorination with sodium bisulfate, followed by a settling basin and then wastewater is pumped through effluent meters to outfalls 001 and 002. Sludge is removed from settling basins as needed. 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 water and wastewater treatment systems are owned and operated by the Town of River Bend. The application describes the system as water treatment plants using Birm sand filtration for iron and manganese removal and using finished water for filter backwash which is dechlorinated prior to sedimentation tanks and discharge. The Town submitted EPA Forms 1 and 2E rather than 2C. They did supply Tables A, B and C from Form C. Given the application submittal being almost a year old and the limited additional data to be gained, the Town was not asked to submit Form 2C. INSPECTION The most recent inspection occurred on March 17, 2021. Regional staff found the facilities to be in compliance with no significant issues noted.

REVIEW OF PERMIT LIMITS: Flow - Treatment plants do not have a flow limit included but flow is monitored for use in any RPA evaluations. In these evaluations the maximum monthly flow is used. This flow is also included in the description of the systems on the permit supplement page. For WTP#1 the maximum monthly flow was 0.014MGD and for WTP#2 it was 0.011 MGD. TSS- TSS values do not appear to be an issue with these facilities. Total Residual Chlorine (TRCj - Combined the two WTP discharges have exceeded the TRC limit around 20% of the time but have had no values above the 50 µg/L compliance level. Turbidity - Turbidity levels do not appear to be high for the facilities. Nutrients -Nutrient levels do not appear to be a major concern for these systems. Monitoring will continue to be included in the permit due to the facilities location in the Neuse River Basin, an NSW watershed. Manganese - There is no water quality standard for manganese so no limits are set under the WTP guidance. However, monitoring is included for facilities that have systems for manganese removal. These WTPs will continue to have manganese monitoring. Whole Effluent Toxicity - The two WTPs have performed WET testing quarterly and have passed all the WET tests over the permit cycle. Reasonable Potential Analysis - there was no data for parameters that require the RPA analysis for these two WTPs. Town of River Bend WTP Fact Sheet NPDES Renewal 2023 - October 30, 2023 / Updated January 2, 2024 Page 3 COMPLIANCE: The facility has not had a documented enforcement action with penalties since 2001. Over the permit cycle there have been three NODS for monitoring frequency violations. The facilities had regular TRC values over their limit, but none of the values was above the 50 µg/L compliance level. FILE HISTORY REVIEW SUMMARY BIMS indicates permit was originally issued March 31, 2000. March 31, 2000 - Permit Issuance. The town requested discharge permit coverage in order to remove the WTP discharge from their wastewater treatment plant. The town wanted to pursue connection of some areas served by septic systems and allow for some additional new connections as well. The initial permit was for discharge of filter backwash with no treatment prior to discharge. The Division determined that the close proximity of the two treatment plant discharges allowed for the issuance of one single permit for the two plants. The effluent limits and monitoring for the two outfalls included: Flow TSS SS TRC Turbidity Iron TN TP (MGD) (mg/L) (mg/L) (µg/L) (NTU) (mg/L) (mg/L) (mg/L) MA DM MA DM DM U/D to meet Monitor - N/A 30 / 45 0.1 / 0.2 28 instream Monitor Concentration Monitor standard and Load The permit included the condition for calculation of TN load etc. October 3, 2003 - Permit Renewal - The only changes in the permit where to add reporting for the components in determining TN values (TKN and NO2+NO3). July 25, 2008 - Permit Renewal - This permit renewal added a flow limit of 0.027 MGD (sum of the monthly discharge from the two WTPs) to determine TN load; removed the suspended solids monitoring and limit; changed the TRC limit to 13 µg/L and added pH with a limit range of 6.8 to 8.5 SU. Turbidity monitoring was not included in the permit. The renewal Fact Sheet noted the application of green sand filter permitting guidance. The package includes schematics for both treatment facilities and notes settling in collection tanks and dichlorination of backwash/rinse waters prior to discharge. Outfall locations were corrected in this permit issuance. The facilities are noted as Class II treatment facilities. February 24, 2009 - Technical Correction to note requirements for Total Suspended Solids rather than Total Dissolved Solids. December 30, 2013 - Permit Renewal -The permit removed the flow limit; removed iron monitoring; added total manganese and turbidity effluent monitoring; changed TN and TP monitoring to concentration monitoring only and adjusted some monitoring frequencies. The permit included more detailed narrative on the supplement page to describe the treatment components. This permit also added requirements for electronic reporting. The facilities are noted as Class I treatment systems. June 18, 2018 - Permit Renewal - This renewal considered the facility's use of Birm media (rather than greensand) and settling in determining that the facilities were hybrid Greensand/Conventional systems. This, along with gathering information for possible general permit coverage, resulted in the major change of adding Whole Effluent Toxicity Testing (WET) to the permit requirements. This was established as a quarterly pass/fall monitoring only requirement. The permit also added regulatory citations as needed. Town of River Bend WTP Fact Sheet NPDES Renewal 2023 — October 30, 2023 / Updated January 2, 2024 Page 4 PROPOSED PERMIT CHANGES: • Updated eDMR requirements to be consistent with final EPA rule. • Added or updated regulatory citations throughout permit as needed. • Updated average flow on supplement page of permit. • Added Flow Duration for reporting in the Effluent Table. • Updated WET conditions language. • Added Special Condition for Nutrient Re -opener in section A.(3.). • Permit map information updated including outfall location coordinates for Outfall 001. PROPOSED SCHEDULE FOR PERMIT ISSUANCE: Draft Permit to Public Notice: November 14, 2023 Permit Scheduled Effective Date: February 1, 2024 STATE CONTACT: If you have questions concerning the above or the attached documents, please contact Bradley Bennett at bradley.bennett@deq.nc.gov . UPDATE To FACT SHEET: In the draft permit the Division had proposed to include WET testing requirements as a limited requirement consistent with draft 2020 WTP Guidance. Further review and internal discussion determined that, given the nature of the discharge and the facility consistently passing the WET tests, it was appropriate to return the permit requirements to monitoring status for their WET requirements. The language has been updated in the final permit.

This is a hybrid greensand/conventional WTP. It previously had monitoring only for WET but based on some discussion with AT we had been moving to WET Limit requirements for these I believe. I have included the Limit WET language in the draft. Please let me know if this is correct. They have passed all of their tests since WET requirements started in 2018. If you think monitoring alone is sufficient for this one we can go back to that requirement.

John said it will likely require some further discussion with ATB on if we want to establish a set criteria and add it to the guidance for future permitting. He agreed that 100% passing rate of TOX tests over 4-5 years should be sufficient to justify changing a facility back from Limit to Monitoring only. I mentioned the River Bend permit and he said based on the facility details (hybrid system, 100% passing), you could continue to keep the TOX testing as Monitoring instead of changing them to Limit for this renewal.

I meant to run some thoughts on this one by you. It is strange because it appears one of the main reasons the WET testing was added last time was to gain information about whether this one would qualify for General Permit Coverage under NCG59. The region indicated they wanted to leave it under the individual permit and since it is strange since it has two separate plants and outfalls, I left it as an individual. They have passed all their WET tests to this point. So, I wasn't really sure if moving them to WET with a limit was necessary. The discussion about adding the limit is from the draft 2020 document right? Should we be adding that without finalization of the draft?

Here are my comments: Permit: • Make sure to add ATB under CC: on the cover letter • eDMR code for Turbidity needs to be updated to 00070 • For the WET testing condition, I would make the effluent concentration and testing months bold, and I would add the citation 15A NCAC 02B .0200 as well. • Map shows two Outfall 001s Factsheet: • Under review of permit limits, the flow for WTP #1 says 0.14 MGD instead of 0.014 MGD My only other thought was regarding WET testing. Conventional WTPs should receive a WET limit instead of just monitoring once they're up for renewal. Greensand facilities do not need WET testing per the guidance. As these facilities are Conventional/Greensand hybrid and WET testing was added in the last renewal, should the WET test be changed from monitoring to limit to be consistent with the way we are permitting Conventionals now, or have we gotten ATB's thoughts on this?

GP and Ind. permit rescind.doc That is different, and it makes sense they should have an individual permit if they have like 2 WTPs in one! There was a letter I believe we were sending out to WTPs to ask them to request the NCG59. This is what both Brianna and Derek told me when I was training in John's unit, for WTPs. I attached an example of that Add Info letter. I don't know what the policy was in terms of identifying which facilities got this letter and which ones did not, or if it was sent to all WTPs.

I did touch base with the regional office and they recommended maintaining the individual permit unless the facility asked for GP coverage. It is a little strange because they actually have two WTPs adjacent to each other that are covered under the one permit. m Bradley Bennett Compliance and Expedited Permitting NC Division of Water Resources 1617 Mail Service Center Raleigh, NC 27699-1617 Phone: (919) 707-3629 Email: brad Iev.ben nettCaMeg.nc.gov Email correspondence to and from this address may be subject to public records laws DEQ is updating its email addresses to @deq.nc.gov in phases from May 1st to June 9th 2023.

I believe we were adding WET testing to be able to evaluate WTPs for coverage under the NCG59, as an analysis of the WET test results are required. In the NCG59 permit writers instructions, dated July 10, 2014: "It is our goal to get all existing and new Greensand WTPs covered under this general permit and all existing (and expanding) Conventional WTPs covered as long as they are not failing* toxicity tests. Due to staffing levels, it is anticipated that the transfer of existing facilities from an individual permit to a general permit will occur upon permit renewal, not sooner. Please note, that this permit does not cover discharges to HQW or ORW waters and to receiving streams with endangered species that can be impacted by this discharge, etc. Also, for Conventional WTPs, upon permit renewal a RPA should be performed on metal(s) and Fluoride (freshwater) effluent data. If a limitation or monitoring is needed for a parameter not limited or monitored in this general permit then the permittee shall maintain an individual permit. New Conventional WTPs are required to obtain an individual permit for one permit cycle. Upon renewal, the Division will evaluate the data and determine if the current individual permit limitations or requirements are sufficient, need to be enhanced, and/or if the standard WTP limitations and requirements set forth in the general permit are adequate to protect the receiving waters for that particular permittee's discharge. If the standard conditions in the general permit are adequate, the permittee will be considered for coverage under the general permit." Hope that is helpful or if there's any other questions.

Looks like you did the last renewal. I noticed in the Fact Sheet that you mentioned adding WET requirements and that these results could be reviewed at renewal to consider coverage under NCG59. I didn't see any other discussion about this and the Town did not request review of potential NCG59 coverage in their renewal application. Do remember anything about this? Was there discussion before or did you just look at the possibility of GP coverage?
