Subject: Review of Permit Renewal DRAFT
NPDES Permit NC0055701, Grade PC-1
Nottingham Forest Water Treatment Plant(WTP)
Off Chowder Road, south of Lake Benson
Wake County
Dear Mr. Becker:
In response to your request to renew the subject permit, the Division of Water Resources
(the Division or DWR) offers this draft for your review and comment. Please review the
attached to insure your understanding of the revised limits and monitoring conditions.
We understand that the subject WTP has made no significant changes to treatment-systems or
treatment processes since last renewal. Note that this facility is not currently eligible for General
Permit NCG590000 (NCG59)because the Neuse River Basin Permitting Strategy requires
specific monitoring not possible under the General Permit, namely Total Nitrogen(TN) and
Total Phosphorus (TP).
Changes to Your Previous Permit:
1. discontinued monitoring for Total Iron and Total Manganese [no longer parameters
of concern for this permit.
2. updated your site-vicinity map, your facility description(see Supplement to
Permit Cover Sheet), and your eDMR text.
3. added regulatory citations to each permit Section for your information.
Division records show that you have successfully registered with the eDMR Program. Please be
reminded that until the state's eDMR application is approved compliant with EPA's Cross-
Media Electronic Reporting Regulation (CROMERR), all permittees must continue to submit
hardcopy of DMRs as backup to eDMR reporting [see permit section A. (2.)].
