Home My WebLink AboutNC0035041_Fact Sheet_20240226FACT 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). Basic Information for Expedited Permit Renewals Permit Writer/Date Sara Bassett 9/18/2023 Permit Number NCO035041 Facility Name Hemby Acres WWTP Basin Name/Sub-basin number Yadkin Pee Dee, 03-07-12 Receiving Stream North Fork Crooked Creek Stream Classification in Permit C Does permit need Daily Max NH3 limits? No — already resent Does permit need TRC limits/language? No — already resent Does permit have toxicity testing? No Does permit have Special Conditions? No Does permit have instream monitoring? Yes Is the stream impaired (on 303(d) list)? Yes For what parameter? Bethos (Nar, AL, FW), Turbidity (50 NTU, AL, FW Any obvious compliance concerns? No. Limit violations for Fecal Coliform in 2020 and BOD 5 day concentration in 2019. Any permit mods since lastpermit? No New expiration date 10/31/2028 Updates for permit Updated ammonia limits: The Waste Load Allocation spreadsheet for this discharge calculated NH3-N limits of 1.0 mg/L for summer and 2.1 mg/L for winter. However, Division policy has established that for small discharges (< 1 MGD) the best available treatment technology for these facilities leads to monthly average limits no lower than 2 mg/L -summer and 4 mg/L — winter. The data reviewed for this renewal would indicate that the facility can meet these permit limits. During the previous permit cycle, evaluating the data with these limits resulted in no violations over the permit cycle. Updated eDMR language Comments on Permit? MRO: The treatment facility exists as described on Supplement to Permit Cover Sheet, Item 1. Review of DMR's for NH3 as N indicate that facility should be able to meet new Ammonia Summer/Winter limits. Change in Final Permit? No changes from draft permit, no comments from Public Notice Most Commonly Used Expedited Language: • 303(d) lan2ua2e for Draft/Final Cover Letters: "Please note that the receiving stream is listed as an impaired waterbody on the North Carolina 303(d) Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required". • TRC lan2ua2e for Compliance Level for Cover Letters/Effluent Sheet Footnote: "The facility shall report all effluent TRC values reported by a NC certified laboratory including field certified. However, effluent values < 50 µg/l will be treated as zero for compliance purposes."
