Subject: Draft NPDES Permit NCO047091
Silver Maples Community WWTP
Class WW-2 WPCS
Cabarrus County
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:
➢ Updated the Owner name on the Cover Sheet and the Supplement to Permit Cover Sheet to Royce Silver
Maples LLC.
➢ Added the facility class to Part I. Section A. (1.).
➢ Updated Section A. (3) to reflect current federal requirements for Electronic Reporting of Discharge
Monitoring Reports.
➢ Added Turbidity to the Impaired Stream Characteristics to reflect the 2020 update to the 303(d) List.
The Rocky River 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 the Rocky
River do 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, 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 his://bit.ly/3k5NFaL//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 Cabarrus 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.
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 [e-mail]

3. After completion of items 1. and 2., the permittee may request that NPDES Permit

A. (3.) ELECTRONIC REPORTING OF DISCHARGE MONITORING REPORTS
[NCGS 143-215.1 (b)]
Federal regulations require electronic submittal of all discharge monitoring reports (DMRs) and
program reports. The final NPDES Electronic Reporting Rule was adopted and became effective
on December 21, 2015.
NOTE: This special condition supplements or supersedes the following sections within Part II of
this permit (Standard Conditions for NPDES Permits):
• Section B. (11.) Signatory Requirements
• Section D. (2.) Reporting
• Section D. (6.) Records Retention
• Section E. (5.) Monitoring Reports
1. Reyortin2 Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)1
The permittee shall report discharge monitoring data electronically using the NC DWR's
Electronic Discharge Monitoring Report (eDMR) internet application.
Monitoring results obtained during the previous month(s) shall be summarized for each month
and submitted electronically using eDMR. The eDMR system allows permitted facilities to enter
monitoring data and submit DMRs electronically using the internet. The eDMR system may be
accessed at: bqs://deg.nc.gov/about/divisions/water-resources/edmr.
If a permittee is unable to use the eDMR system due to a demonstrated hardship or due to the
facility being physically located in an area where less than 10 percent of the households have
broadband access, then a temporary waiver from the NPDES electronic reporting requirements
may be granted and discharge monitoring data may be submitted on paper DMR forms (MR 1,

1.1, 2, 3) or alternative forms approved by the Director. Duplicate signed copies shall be
submitted to the following address:
NC DEQ / Division of Water Resources / Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
See "How to Request a Waiver from Electronic Reporting" section below.
Regardless of the submission method, the first DMR is due on the last day of the month
following the issuance of the permit or in the case of a new facility, on the last day of the month
following the commencement of discharge.
Starting on December 21, 2025, the permittee must electronically report the following
compliance monitoring data and reports, when applicable:
Sewer Overflow/Bypass Event Reports;
Pretreatment Program Annual Reports; and
Clean Water Act (CWA) Section 316(b) Annual Reports.

Waiver from Electronic Reporting" section below).
2. Electronic Submissions
In accordance with 40 CFR 122.41(1)(9), the permittee must identify the initial recipient at the
time 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/2015/10/22/2015-24954/national-pollutant-
discharge-elimination-system-npdes-electronic-reporting-rule
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

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.
