This permit is reissued pursuant to the requirements of North Carolina General Statute 143-215.1 and the Memorandum of Agreement between the state of North Carolina and the U.S. Environmental Protection Agency, dated October 15, 2007 (or as subsequently amended). The following information is included with your permit package: • A new Certificate of Coverage • A copy of General Permit NCG140000 • A copy of the Technical Bulletin for the General Permit • Two copies of the Discharge Monitoring Report (DMR) Form for Stormwater • Two copies of the DMR Form for Wastewater • Two copies of the Qualitative Monitoring Report Form The General Permit authorizes discharges of stormwater and/or wastewater, and it specifies your obligations with respect to discharge controls, management, monitoring, and record keeping. Please review the new permit to familiarize yourself with all the changes in the reissued permit. If your Certificate of Coverage (COG) restricts authorization to discharge stormwater only (or other limited terms), you must contact the Stormwater Permitting Unit if you would like to request a modification to your COC. The first sample period of your permit begins July 1, 2011. However, because of the delayed mail -out of permit packages, your facility is expected to attempt to sample during the first sampling period, and must comply with sampling requirements beginning during the second sampling period. Your facility must sample a representative storm event between January 1 and July 30, 2012 (for stormwater sampling), and/or sample wastewater between October 1, 2011 and December 31, 2011 (or, if applicable, report "No Flow", as outlined in Part V, Section E). Additionally, your facility has 6 months from the time of receipt of the permit to update SPPP to current standards. The more significant changes in the General Permit since your last Certificate of Coverage include the following (please note the names and numbers of sections have been changed from the previous permit revision): • Part II: • Authorization to Construct (ATC) language was added to the permit and adapted to fit NCG140000. • Part III: • The Stormwater Pollution Prevention Plan (SPPP) section has been updated to the most current language of our permits. Some additional conditions specific to this industry have been added to the SPPP language. • Part IV: • Sections A & B: Revised provisions require stormwater discharges be sampled twice per year (instead of annually), and sampling results shall be compared to new benchmark values.
