Subject: Draft NPDES Permit NC0061492
Maury Sanitary Land District WWTP
Grade WW-2 WPCS
Greene County
Dear Permittee:
The Division has reviewed your request to renew the subject permit. Enclosed with this letter is a copy
of the draft permit for your facility. 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:
➢ Added a footnote about Total Residual Chlorine (TRC) for the table in Part I. A. (1)
➢ Added a nutrient reopener condition for all Neuse River discharge permits in Part I. A. (4.).
➢ Updated eDMR language for electronic data submission in Part I. A. (5).
The segment of the Contentnea Creek to which your facility discharges is listed as an impaired stream
on North Carolina's 303 (d) list. Currently, the stream does not meet all water quality standards. If the
limitations in the current permits for facilities discharging to this segment of the Contentnea Creek do
I not result in improved water quality, removal of discharges may be necessary for the health of the
stream.
We will continue to monitor compliance at your facility. If noncompliance with your permit's effluent
limits is shown to be a direct cause of stream degradation to this segment of the Contentnea Creek, the
Division will recommend removal of your facility's discharge.
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/3k5NFaL 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 Greene County area, per EPA requirements.
Please provide your comments, if any, to me at the e-mail address below no later than 30 days
after receiving this draft permit.

of each electronic submission. The permittee should use the EPA's website resources to identify the
initial recipient for the electronic submission.
Initial recipient of electronic NPDES information from NPDES-regulated facilities means the entity
(EPA or the state authorized by EPA to implement the NPDES program) that is the designated entity
for receiving electronic NPDES data [see 40 CFR 127.2 (b)].
EPA plans to establish a website that will also link to the appropriate electronic reporting tool for
each type of electronic submission and for each state. Instructions on how to access and use the
appropriate electronic reporting tool will be available as well. Information on EPA's NPDES
Electronic Reporting Rule is found at: https://www.federalregister.gov/documents/2015/10/22/2015-

Electronic submissions must start by the dates listed in the"Reporting Requirements" section above.
3. How to Request a Waiver from Electronic Reporting
The permittee may seek a temporary electronic reporting waiver from the Division. To obtain an
electronic reporting waiver, a permittee must first submit an electronic reporting waiver request to
the Division. Requests for temporary electronic reporting waivers must be submitted in writing to
the Division for written approval at least sixty (60) days prior to the date the facility would be
required under this permit to begin submitting monitoring data and reports. The duration of a
temporary waiver shall not exceed 5 years and shall thereupon expire. At such time, monitoring data
and reports shall be submitted electronically to the Division unless the permittee re-applies for and is
granted a new temporary electronic reporting waiver by the Division. Approved electronic reporting
waivers are not transferrable. Only permittees with an approved reporting waiver request may
submit monitoring data and reports on paper to the Division for the period that the approved
reporting waiver request is effective.
Information on eDMR and the application for a temporary electronic reporting waiver are found on
the following web page:
