Please see the attached new Certificate of Coverage No. NCG020689 for coverage under
Stormwater General Permit NCG020000 for this facility. 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.)
You must print a copy of the new NCG02000 General Permit from our Stormwater
General Permits web page: httl2s:Hdeq.nc .gov/about/divisions/energy-minera I- land-
resources/npdes-stormwater-gps. In addition to the full permit, the print package on the
website includes revised Discharge Monitoring Report (DMR) forms and Qualitative
Monitoring Report Forms.
The General Permit authorizes discharges of stormwater, 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 changes in the reissued permit. Your facility has six
(6) months from receipt of the permit to update your Stormwater Pollution Prevention Plan
(SPPP) to reflect any new permit requirements.
When does electronic DMR (eDMR) reporting start, and does it affect this permit?
If activities at this facility ever require analytical monitoring, eDMR will affect you. We
are setting up our database with the outfalls that permittees submitted on-line and permit
parameters. Permittees will receive notification when our eDMR system is ready for
permit -holders to register and begin reporting monitoring data electronically. If you
have any questions about the status, please contact Bethany Georgoulias at (919) 707-
3641.
