Environmental Protection Agency dated October 15, 2007, or as subsequently amended.
We have made the following updates to your previous permit:
➢ Section A. (7) has been added•to require electronic submission of effluent data. Federal
regulations require electronic submittal of all discharge monitoring reports (DMRs), effective
December 21, 2016.
➢ Regulatory citations have been added to the permit.
➢ An updated outfall map has been included.
We have made the following updates since the draft permit:
➢ The monitoring coalition name in the footnotes section of both A. (1) and A. (2) has been
changed from Middle Cape Fear River Basin Association to Middle Cape Fear Basin
Association.
Starting on December 21, 2016, federal regulations require electronic submittal of all discharge
monitoring reports (DMRs) and specify that, 1f a state does not establish a system to receive such
submittals, then permittees must submit DMRs electronically to the Environmental Protection
Agency (EPA). 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 A. (7)] For information on eDMR, registering for eDMR and obtaining an
eDMR user account, please visit the following web page:

[15A NCAC 02B.0200 et seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or
significant mortality to Ceriodaphnia dubia at an effluent concentration of 67%.
The permit holder shall perform at a minimum,
quarterly monitoring using test
procedures outlined in the "North Carolina Ceriodaphnia Chronic Effluent Bioassay
Procedure," Revised December 2010, or subsequent versions or "North Carolina Phase II
Chronic Whole Effluent Toxicity Test Procedure" (Revised- December 20 10) or
subsequent versions. The tests will be performed during the months of January, April,
July and October. These months signify the first month of each three-month toxicity
testing quarter assigned to the fafenlut ldis barge anduent lshall be performed at ng for this testing the NPDES
t be
obtained during representative of
permitted final effluent discharge below all treatment processes.
If the test procedure performed as the first test of any single quarter results in a
failure or ChV below the permit limit, then multiple -concentration testing shall be
performed at a minimum, in each of the two_following months as described in
"North Carolina Phase II Chronic Whole Effluent Toxicity Test Procedure" (Revised -
