Dear Ms. Coffee:
Enclosed with this letter is a copy of the draft permit for your facility. Please review this permit very
carefully to ensure thorough understanding of the conditions and requirements it contains.
The Draft Permit contains the following significant changes from your existing permit:
• Federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and program reports. The final NPDES Electronic Reporting Rule was adopted and became
effective on December 21, 2015. The requirement to begin reporting discharge monitoring
data electronically using the NC DWR's Electronic Discharge Monitoring Report (eDMR)
internet application has been added to your final NPDES permit, (See Special Condition A.
(7.)).
For information on eDMR, registering for eDMR and obtaining an eDMR user account,
please visit the following web page: http://deq.nc.gov/about/divisions/water-

• The water quality based effluent limits for Total Silver were added to the permit based on the
results of the Reasonable Potential Analysis.
• The water quality based Monthly Average effluent limit for Bis(2-ethylhexyl) phthalate was
added to the permit based on the results of the Reasonable Potential Analysis.
• The Total Hardness monitoring was added in the permit to facilitate implementation of the
new dissolved metals standards.
