None noted in the application New expiration date: January 31, 2028 FACILITY OVERVIEW: This facility is 100% domestic waste and treats a subdivision serving 160 residential connections and a population of 400 people. The facility has a permitted flow of 0.22 MGD and as built flow rate of 0.05 MGD. The permit also contains an intermediate phase flow of 0.11 MGD. The treatment system includes the following wastewater treatment components: • Influent pump station • Influent bar screen • Aeration basin • Two sludge holding tanks (7,500 gallons and 12,000 gallons) • Clarifier • UV Disinfection • Contact chamber (used for flow measurement purposes and backup chlorination) • Effluent pump station • Post Aeration • Sludge drying beds APPLICATION The application does not indicate any changes in the facility or treatment since the last modification of the permit in 2018. The treatment system is owned and operated by Clarke Utilities, Inc. The annual average daily flow is indicated as 0.029 MGD over the last two years, so the facility is operating at well below its designed and permitted capacity. The permittee had submitted a modification request in 2019 that appears to be to add in wastewater from a water treatment plant (Glen Greek Subdivision in Garner). DWR requested additional information on this modification request, but the permittee never provided a response to the request. The Add -Info requested noted that if there was no response the application would be deactivated. This did not happen at the time, and the modification request was still in BIMS. The modification was returned in BIMS as part of this review (January 2023) and is no longer under review. INSPECTION The most recent inspections occurred on February 2, 2023. Recent DMR violations were discussed, and the report noted that the sludge holding tank was full but was being pumped within the next week. The inspection did not note any issues of concern with the facility.

REVIEW OF PERMIT LIMITS: Flow - The facility is operating on average at around 58% of the as -built flow (0.05MGD) allowed by the permit. None of the 60 monthly average values was above 0.034 MGD. These data assessments included removing one outlier value of 344 MGD reported in December 2022. This value was four orders of magnitude higher than other reported values and was obviously inaccurate. Deer Chase WWTP Fact Sheet NPDES Renewal 2023 - April 21, 2023 Page 2 BOD / Fecal- There were no violations of BOD and Fecal limits. The facility monitors upstream and downstream for fecal in addition to effluent monitoring. U/D monitoring for fecal show regular values that are high. 291 instream fecal values out of 520 total instream samples were above 200 (#/mL). It is unclear why these instream values are high. The effluent fecal values reported have never been above 21/mL. Nearly 90% of effluent fecal values have been reported as less than 1. So it is apparent that the discharge is not a fecal issue. TSS- The were no violations for TSS in this permit cycle. Ammonia (NH3-N) and Whole Effluent Toxicity (WETS- Under the current active flow limit (0.05MGD) this facility has had NH3-N limits and WET requirements since the early 1990's. Documentation in this time frame shows that the permittee accepted the addition of WET requirements and existing NH3-N limits rather than receiving more stringent NH3-N limits. Revised ammonia criteria, consistent with EPA requirements, no longer allow for the use of action level standards (like WET testing in this case) to be used in place of otherwise required chemical limitations (more stringent NH3-N limits). In response to this adjustment the WET requirement in this permit has been reviewed for removal. Removal of the WET requirements would also result in changes to the NH3-N limits in the permit as well. These issues are discussed below The facility is a 100% domestic wastewater discharger that has been in compliance with the WET testing requirements over the last five years. The facility did have some toxicity failures in the first quarter of the permit (early 2018) but has had no issues since that time. The Aquatic Toxicology Branch and Raleigh Regional Office staff have been contacted about removal of the WET requirement (emails attached). No issues were raised with removal of the WET requirement in the permit. Over the last permit cycle there was one violation of NH3-N summer limits that resulted in an NOV. With the removal of the WET requirements the Division has evaluated passed permit renewals to determine the necessary permit limits for NH3-N. Previous Waste Load Allocation (WLA) files were reviewed to assess modeling results for the potential impact of NH3-N from the discharge as an oxygen consuming waste. In addition, the WLA spreadsheet completed and attached in this Fact Sheet was evaluated for the potential impact of NH3-N as a toxicant. The most stringent limit applicable for the 0.05 MGD flow from these assessments was determined and resulted in a change in the summer NH3-N limits. The proposed summer limits are - monthly average of 2.0 mg/L and a daily max of 10.0 mg/L. The winter limit is unchanged. Based on the eDMR data from the previous permit cycle it is possible that these limit changes could have resulted in a few additional limit violations for the permittee. Consideration will have to be given to any needed operational adjustments to assure ongoing compliance with the new limits. The draft permit proposes to allow an eighteen (18) month compliance period for this change with the new limits being effective 18 months from the effective date of the issued permit. The previous summer limits (5 and 25) will remain in place for the first 18 months of the permit. Nutrients Total Nitrogen load numbers over the permit cycle included a maximum annual load of slightly over 498 lbs. This annual load is well below that discharge allocation load of 4,448 lbs. Total Phosphorous is monitoring only in the permit with no limit and values do not appear to show any issue. The permit effluent tables previously included an eDMR code of 00600 for the TN loading numbers. These codes have been corrected to QM600 for monthly load and QY600 for annual load. COMPLIANCE: This facility had four (4) violations during the permit term. Three of these violations were in the first quarter of 2018 after the permit was first renewed and were for WET violations. These WET violations resulted in one enforcement case with a $3,000 penalty and $60.20 enforcement cost. There have been no additional WET test failure since that time. Aquatic Toxicology has noted one recent reporting issue in January 2023. In this Deer Chase WWTP Fact Sheet NPDES Renewal 2023 — April 21, 2023 Page 3 instance the permittee reported a passing WET test requirement in eDMR but did not submit the separate AT form. The permittee has failed to pay enforcement assessments from 2017 and 2018 totaling $3,349.47.

Division staff inspected the creek and proposed the flows to be used. August 21,1987 WLA - This WLA is done for two flows, 0.11 MGD and 0.22 MGD with flow numbers set at 7010(sl= 0: 7010(w) = 0.85 cfs; 3002 = 0.30 cfs and average flow = 3.0 cfs.

This package also outlines that the WLA resulted in more stringent NH3-N limits, but the permittee choose to maintain exiting limits and add WET testing requirements. The document did not clearly indicate what levels the NH3-N limits would be at without the addition of WET requirements. Documents note that existing flow is at 0.05 MGD and there have been no requests for ATC for expansion. The documents also discuss need for alternatives analysis for any expansion and notes that the facility is existing and therefore does not have TP or Chlorine limits at this time. A letter on Chlorine toxicity and the need to eventually meet 17µg/L limit was also in the WLA package. February 25, 1993 WLA - This WLA is done for three flows, 0.05 MGD, 0.11 MGD and 0.22 MGD with flow numbers set at 7Q10(s)= 0; 7Q10(w) = 1.4 cfs; 30Q2 = 0.50 cfs and average flow = 5.0 cfs.

Instream monitoring for temperature, DO, conductivity and fecal. Flows were recalculated based on USGS report, but not utilized due to impact of beaver dam along the creek. July 19, 1999 - Authorization to Construct (ATC) - Authorization for modification to existing 0.05 MGD system to install a 12,000 gallon sludge holding tank; alter existing blowers and add additional piping, valves etc. as needed. • October 11, 2000 Permit Renewal.

The permit also includes Temperature monitoring (E,U,D), DO (U/D) and Fecal (U/D) and Quarterly WET monitoring at the 0.05 MGD flow. The permit includes Special Conditions for WET; Total N load calculation; Wastewater Management Plan within 180 days and an Alternative Analysis prior to expiration of the permit. The WET requirement is noted as being maintained due to the facility's failed tests in the past and no good information on the cause of the failures. The review document notes that connection to the Town of Wake Forest WWTP doesn't appear to be an option because the plant is within the limits of Rolesville. This draft was prepared in 1998 but was part of a request for Public Hearing for a large number of facilities by the Neuse River Foundation. As Neuse River Management Strategy rules were developed, these permits were finalized. • Wastewater Management Plan - Submitted April, 2001 to meet permit condition for Plan submittal. • March 17, 2003 - Memo to Division staff about relocation plan for an aeration structure on the effluent force main. • April 17, 2003 Permit Renewal - Package included the Wastewater Management Plan and Alternatives Analysis required in the previous permit. The alternatives analysis looked at potential options including connection to the Wake Forest WWTP, onsite non -discharge, spray irrigation systems, etc. All of these alternatives were found to be cost prohibitive or not technically possible. The permit documents also include a 2002 Assessment Report for the Toms Creek Watershed that notes chlorine from the Deer Chase WWTP as one possible factor in stream impairment. The permit included modification of NH3-N limits to add DM limits under each flow level. For 0.05MGD NH3-N DM limits (S and W) of 25 and 35mg/L. For 0.11 and 0.22MGD flows DM limits of 10 and 20 mg/L. All flows included the addition of TRC daily max limit of 17µg/L that became effective 18 months after the effective date of the permit. The permit required, for all three flows, that the components of TN be reported separately and set the DO limit at 5mg/L. The permit also included a Special Condition to update the Engineering Alternatives Analysis prior to any expansion of the WWTP. • June 20, 2003 - Permit Modification to clarify toxicity test sampling months (Jan, April, July and Oct.) • November 21, 2003 - Permit Modification to correct toxicity test effluent concentration of 90% rather than 5.5%. • April 13, 2004 - Permit Name/Ownership Change - Permit issued to Clarke Utilities, LLC as new owner. • March 12, 2007 - ATC for installation of a dechlorination system utilizing sodium sulfite under the fast -track system and in accordance with minimum design criteria. • March 21, 2007 -ATC for modifications to the existing 0.05 MGD WWTP for the installation of a UV disinfection system with audible and visible alarms. The chlorinator and dechlorinator remain in place as backup. • May 15, 2008 - Permit Renewal - The permit includes updated treatment system components to account for the added UV system. Also adjusts owner name to Clarke Utilities, Inc., and updates WWTP location to 3504 Donner Trail. The permit adds special conditions for Annual Limits for Nitrogen and Total Nitrogen Allocations. The permittee had asked for reduction in WET requirements, but the Division did not approve Deer Chase WWTP Fact Sheet NPDES Renewal 2023 — April 21, 2023 Page 5 any changes because the system discharges to waters impaired for biological integrity. Notes from Wake County staff that had inspected the facility indicated one sludge holding tank not operational due to corrosion damage to the wall of the tank. • July 13, 2013 - Permit Renewal - The permit increased nutrient monitoring from monthly to 2/month and also removed the special condition for Total Nitrogen limits since the facility doesn't have TN mas limits. The permit updated treatment system components to note that both sludge holding tanks were operational. • January 6, 2018 - Permit Renewal - This renewal added electronic submittal language for DMRs, added regulatory citations and updated the permit map. • September 11, 2019 - Permit Modification Documents - Various information is included in the files related to a modification request that seeks to add WTP wastewater from the Glen Creek Subdivision. • January 27, 2020 - Additional Information Request (in LF) - The Division asks for additional information on the 2019 modification request before review of the request can continue. The letter indicates that if there is no response within 60 days, the project will be deactivated. This modification request was still showing as under review in BIMS when the initial review for the 2023 renewal started. After emails with the permit reviewer, RRO staff and other DWR staff it was determined that no response was ever received from the permittee on this add -info request. The project was deactivated by Returning the application in BIMS on January 18, 2023. PROPOSED PERMIT CHANGES: • Updated eDMR requirements to be consistent with final EPA rule. • Added or updated regulatory citations throughout permit as needed. • Language in paragraph 2 of the Supplement to Permit Cover Page has been adjusted to outline requirements prior to operating at the 0.11 and 0.22 MGD levels. • eDMR codes for BOD, TSS, NH3-N, TN and TP updated to replace initial 0 with C. Added code for Total flow - 82220. • eDMR codes for TN load have been corrected to note QM600 for monthly and QY600 for annual load. • Footnotes in the effluent tables have been updated with current language where needed. • Corrected descriptive language above effluent table in Section A. (3.) to refer to 0.22MGD flow. • Permit map information updated including correcting location of the discharge point that was inaccurate in 2018 permit. • Added Special Condition for Nutrient Re -opener in section A.(7.). • Monitoring requirements for WET have been removed from the permit. This has also resulted in a change in the summer NH3-N monthly average limit from 5.0 mg/L to 2.0 mg/L. This will also result in the daily max limit being reduced to 10.0 mg/L (five times the monthly average). These changes will be given an 18-month compliance schedule from the effective date of the permit.

They did, however, fail to send you guys their AT form in January which led to an NOV from you guys. But they did pass that test and noted it in the eDMR.

I am working on permit renewals for these two Clarke Utilities facilities and noticed that you had done the most recent inspections earlier this year. I just wanted to get in touch and see if you had any comments about the renewals that you wanted to pass along. I have a draft for Whippoorwill Valley in the works now and have done a little work on Deer Chase. I hope to send these to you for review soon and then on to notice. One thing I wanted your input on for Deer Chase is their WET requirements. It looks like they have been consistently passing these and recently the Aquatic Tox staff have indicated that we should remove WET requirements for these 100% domestic discharges if there are no noted problems. Do you have any concerns about potentially eliminating WET requirements for Deer Chase? Thanks for tour help.

I had a quick question about this one. The permit expires at the end of the month and has been assigned to me. When I started looking at info in BIMS and Laserfiche on it I found that there was a permit application that looks like a Mod to maybe add in some water treatment plant discharge to the system. This started in 2019 and looks like you sent an add info in early 2020 that they never responded to? The application still shows as in draft in BIMS. In the letter you indicated that if we did not receive a response from them the project would be deactivated, but it is still in BIMS. Can you give me any more info on what happened with this one. They have not submitted an actual renewal application since that submittal so I think they need to do that because it looks like this request didn't go anywhere? Thanks for any help you can give. If we need to talk let me know and we can set up a Teams call.
