Subject: Draft of NPDES Permit NCO060321
First Craven Sanitary District WTP
Craven County
Grade I Physical Chemical WPCS
The Division has reviewed your request to renew the subject permit. Please review this draft carefully to ensure a
thorough understanding of the information, conditions, and requirements it contains.
This draft contains the following major changes from the existing permit:
➢ The limits for Total Copper, Total Lead, and Total Zinc have been removed as the RPA did not show a
reasonable potential to exceed water quality standards; quarterly monitoring has been implemented for
these parameters.
➢ Duration of Discharge monitoring has been added in Section A. (1) Effluent Table
➢ Ammonia Nitrogen monitoring has been removed added in Section A. (1) Effluent Table as this facility
has not reported use of chloramines.
➢ Section A. (3) outlining the previous compliance schedule has been removed.
➢ The Supplement to Cover Sheet has been updated with the new maximum monthly average.
➢ The facility grade has been added to Section A. (1).
➢ Monitoring for Total Iron in Section A. (1) Effluent Table has been removed as there is no longer a water
quality standard, per 2012 WTP guidance.
➢ Section A. (3) has been updated regarding electronic submission of effluent data. Federal regulations
require electronic submittal of all discharge monitoring reports (DMRs).
With this notification, the Division will solicit public comment on this draft permit by publishing a notice in
newspapers having circulation in the general Craven County area, per EPA requirements. Please provide your
comments, if any, to me no later than 30 days after receiving this draft permit.
Following the 30-day public comment period, the Division will review all pertinent comments and take
appropriate action prior to issuing a final permit. If you have questions concerning the draft, please contact me via
e-mail at [e-mail] or via phone at 919-707-3600.
Sincerely,
Sara Bassett

THAN TRACE AMOUNTS.
A. (2.) CHRONIC TOXICITY PASS/FAIL PERMIT LIMIT (QUARTERLY)
[15A NCAC 02B .0200 et. seq.]
The effluent discharge shall at no time exhibit observable inhibition of reproduction or significant
mortality to Mysidopsis Bahia at an effluent concentration of 90 %.
The permit holder shall perform at a minimum, quarterly monitoring using procedures described below
to establish compliance with the permit condition. 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 facility. Effluent sampling for this testing must be obtained during
representative effluent discharge and shall be performed at the NPDES 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 EPA Method 1007.0, Mysid, Mysidopsis Bahia,
Survival, Growth, and Fecundity Test, as described in Short -Term Methods for Estimating the
Chronic Toxicity of Effluents and Receiving Waters to Marine and Estuarine Organisms, Third
Edition, EPA821-R-02-014, October 2002.
The test procedure will be based on EPA Method 1007.0, Mysid, Mysidopsis Bahia, Survival, Growth,
and Fecundity Test, as described in Short -Term Methods for Estimating the Chronic Toxicity of Effluents
and Receiving Waters to Marine and Estuarine Organisms, Third Edition, EPA-821-R-02-014, The
procedure will be performed as written with the following exceptions:
