Dear Mayor Braxton:
The Division has reviewed your request to renew the subject permit. Please review this draft carefully
to ensure your thorough understanding of the information, conditions, and requirements it contains.
The draft permit includes the following significant changes from the existing permit:
1. Language has been updated in Section A. (1) and Section A. (4)to require electronic submission
of effluent data. Federal regulations require electronic submittal of all discharge monitoring
reports(DMRs).
2. Outfall map has been updated.
3. The Cover Sheet has been updated to reflect the 4 sections of the boilerplate.
4. Permit expiration date has been changed to be in-line with the basin permitting schedule. The
permit is being short-cycled due to this.
5. The components list has been added and language updated on the Supplement to Permit Cover
Sheet.
6. The facility grade has been added in Section A. (1).
7. Parameter codes have been added in Section A. (1).
8. Limits have been added and monitoring increased to monthly for total chloride in Section A. (1)
based on a reasonable potential to exceed water quality standards. A compliance schedule has
been added as Section A. (3).
9. Monitoring for iron has been removed in Section A. (1) as there is no longer a water quality
standard.
10. Monitoring and associated footnotes for total hardness have been added in Section A. (1) per the
current water treatment plant guidance.
11. Updated the footnotes in Section A. (1).
12. Toxicity language in Section A. (2) has been updated.
13. The discharge alternatives evaluation in former Section A. (3)has been removed as the Town of
Vanceboro has completed the evaluation.

The NC 2007-2014 Water Quality Standard (WQS) Triennial Review was approved by the NC
Environmental Management Committee (EMC) on November 13, 2014. The US EPA subsequently
approved the WQS revisions on April 6, 2016 with some exceptions. The NC Division of Water
Resources NPDES Permitting Unit is required to implement the new dissolved metal standards in all
permits public noticed after April 6, 2016.
The new standards for most metals include acute standards. Further, the freshwater standards for several
metals are expressed as the dissolved form of the metals, and seven metals have hardness-dependent
equations. As a result, the NPDES Permitting Unit will need site-specific effluent hardness data and
instream hardness data, upstream of the discharge, for each facility monitoring these metals in order to
calculate permit limitations. Effluent hardness and instream hardness sampling, upstream of the
discharge, has been added to this permit at a monitoring frequency of quarterly. See Section A. (1)
Effluent Limitations and Monitoring Requirements.
The NPDES standard conditions (Parts II, III, and IV)that are a part of the permit are not included in
this draft document(cover, map, and Part I). The conditions are the same as in your current permit
except that agency and division names have been updated. The latest version is available
at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.
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 at 919-707-3619, or via e-mail [[e-mail]].
