Dear Mr. Simons:
In response to your request to renew the subject NPDES permit, the Division of Water Resources (DWR or
the Division) hereby transmits this draft for your review and comment. Please review this document to assure
your understanding of the permit limits and monitoring conditions, and to correct errors, if any.
The Division understands that you have made no significant changes to your facility since the last permit
renewal. We have made the following updates to your previous permit:
1. The facility map has been updated.
2. Regulatory citations have been added.
3. Parameter codes have been added to Section A. (1).
4. Electronic reporting of discharge monitoring reports (eDMR) has been added in Section A. (2.).
5. A Mercury TMDL evaluation did not indicate a limit was needed. Therefore, Total Mercury
monitoring has been removed.
6. Total Nitrogen (TN) and Total Phosphorus (TP) effluent monitoring has been increased to monthly
sampling. Additionally, TN and TP mstream monitoring has been added with monthly grab sampling.
This monitoring has been added for the Division to investigate sources of nutrients in the Tuckasegee

7. The outfall location has been adjusted to the following coordinates:
Latitude 350 25' 20" N
Longitude 830 27' 42" W
Concurrent with this notification, the Division will solicit public comment on this draft by publishing a notice
