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).

If there is noncompliance with permitted effluent limits and stream impairment can be attributed to your facility, then mitigative measures may be required". • TRC language for Compliance Level for Cover Letters/Effluent Sheet Footnote: "The Division shall consider all effluent TRC values reported below 50 µg/L to be in compliance with the permit.

BIMS Compliance Download: Queries>Reports>Violations>Monitor Report Violations>Limit Violations for Past 3 Years Reminder: Permits that are not subject to expedited renewal include the following: 1) Major Facility (municipal/industrial); 2) Minor Municipals with pretreatment program; 3) Minor Industrials subject to Fed Effluent Guidelines (lb/day limits for BOD, TSS, etc); 4) Limits based on reasonable potential analysis (metals, GW remediation organics); 5) Permitted flow > 0.5 MGD (requires full Fact Sheet); 6) permits determined by Supervisor to be outside expedited process. Note: This sheet is located on NPDES Server/CurrentVersions/Expedited Fact Sheet May2010 NC0025526 Town of Walnut Cove WWTP The existing permit does not require analysis of the effluent for dissolved oxygen; however the facility has been reporting DO data on its DMRs. It is not being entered into BIMS. The facility is required by its permit to measure the DO in Town Fork Creek upstream and downstream of the discharge. Visual examination of the DMRs from 2010 and 2011 indicates the effluent DO concentration can be very low (at times < 3.0 mg/L) during the summer. This may have more to do with the design of the system than its performance efficiency. The WWTP's main treatment is provided by lagoons and constructed wetlands. No aeration of the effluent is provided prior to discharge to the stream. The DMRs show expected seasonal variation of the DO content within Town Fork Creek. Downstream DO (300 feet below the discharge) does appear to be retarded by the discharge, but rarely did the data show values below 5.0 mg/L. Modeling data within the file indicate the stream can accommodate the loading from the WWTP at the permitted levels. The DO sag is lowest about 3 miles downstream of the WWTP; it then recovers prior to the creek's confluence with the Dan River.

Are there any special conditions you'd like for me to put in the new permit that may compel them to address those issues?
