Subject: Discontinuance of Fecal Coliform Monitoring
NPDES PermitINC0023965
Dear Mr. Vogt:
On November 30, 2007, the US Environmental Protection Agency approved revisions to the
North Carolina water quality standards included in 15A NCAC 2B .0200. These revisions included
changes in the water quality standards for bacterial indicators in SB and SC waters. Fecal coliform is
no longer included as a standard for waters classified as SB or SC. The Enterococci standard replaces
the fecal coliform standard for those waters.
The requirements for fecal coliform in your NPDES permit specified that you had to monitor
until this new rule became effective. Therefore, as of November 30, 2007, the fecal monitoring may be
discontinued. However, you must continue to monitor for Enterococci as indicated in your permit.
This change requires no formal NPDES permit amendment or any other actions at this time. If
you have any questions please contact Karen Rust at phone number 919-807-6400.
Sincerely,
Gil Vinzani, P.E.
Supervisor, Eastern NPDES Program
