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 Emily Richards Permit Number NC0020346 Facility Name Magnolia WWTP Basin Name/Sub-basin number Cape Fear / 03-06-19 Receiving Stream Stewarts Creek Stream Classification in Permit C-Swamp Stream Index: 18-68-2-10 Does permit need Daily Max NH3 limits? No — Does permit need TRC limits/language? No — already present Does permit have toxicity testing? No Does permit have Special Conditions? No Does permit have instream monitoring? Yes — Dissolved oxygen, fecal coliform, conductivity, and temperature Is the stream impaired (on 303(d) list)? No Any obvious compliance concerns? Any permit mods since last permit? No New expiration date 1/31/2022 Changes to 2016 Permit? Updated eDMR requirements Updated HUC Changes to Draft Permit? none Facility Background: This facility is a Minor Municipal WWTP discharging < 1 MGD and includes the following components: • Influent mechanical screen • Influent flow meter with composite sampler • Influent pump station w • Dual extended air activated sludge treatment reactors • Dual 20-foot diameter center feed secondary clarifiers • RAS/WAS pump station • Dual microscreen drum filters • UV disinfection (2 channel banks in series) • Post -aeration with diffusers • Effluent pump station • Effluent flow meter with composite sampler • 500-gpm sludge loading station transfer • 89,900-gallon sludge digester with fine air diffusers • 200 kW emergency generator DocuSign Envelope ID: 15CD44AE-3726-45C7-A7FD-6CF05F4683B9 Compliance History: Two limit violations in 2018 - one for fecal coliform weekly geo mean, one for BOD5 weekly avg. A 2021 inspection noted that the facility was "marginally compliant" and cautioned the Town against letting its Operation and Maintenance degrade any further. The facility generally operates at -40% of its flow capacity. The Town seems to be struggling to operate with staffing and budget constraints.
