Subject: Draft NPDES Permit NCO087491
Chocowinity/ Richland Township WTP
Grade I Physical Chemical WPCS
Beaufort County
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.
The draft permit includes the following significant changes from the existing permit:
The facility classification Grade I Physical Chemical Water Pollution Control System (WPCS) was
added to the effluent page.
2. The chronic toxicity monitoring special condition A. (3.) was updated.
3. The electronic reporting permit special condition A. (4.) was updated.
4. The permit map was updated.
Please note that the Pamlico River is listed as an impaired waterbody on the North Carolina 303(d)
Impaired Waters List. Addressing impaired waters is a high priority with the Division, and instream data
will continue to be evaluated. If there is noncompliance with permitted effluent limits and stream
impairment can be attributed to your facility, then mitigative measures may be required.
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 Beaufort County area, per EPA requirements.
Please provide your comments, if any, to me at the address below 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.

discharge below all treatment processes. The test procedure will be based on EPA Method 1007.0,
Mysid, Mysidopsis Bahia, Survival,. Growth, and Fecun 'ty Test, as described in Short -Term Methods
for Estimating the Chronic Toxicity ofEffZuents and Re ing Waters to Marine and Estuarine
Organis ird Edi4# EPA-821-R-02-014. ure will be performed as written with the

Should there be no discharge of flow from the facility during a month in% hich toxicity monitoring is
required, the permittee will the information located at the top o e aquatic toxicity (AT) test

require will revert to rly in4olkiionths specified above. Should any test data from this
monitorin irement or to formed by the North Carolina Division of Water Resources indicate
potential imp o the receivin eam, this permit may be re -opened and modified to include alternate
