Subject: Pending Return of Renewal Application
DRAFT NPDES NCO081825
Ansonville WWTP, WTPS Grade WW-II
Anson County
Mr. Mull:
On November 15, 2023, the Division of Water Resources (DWR or the Division) acknowledged
receiving Ansonville's application to renew the subject permit, signed by you on November 16,
2023. We note however that the application does not include the required one-time analysis for
Total Mercury (APP page 17). This oversite could delay renewal.
Similar to your last renewal, your Total Mercury (Hg) effluent analyses was due six (6) months
prior to permit expiration. To Date DWR has no record of your Total Mercury analytical results.
This is a permit violation.
Civil Penalty Assessment (CPA). Failure to report Mercury subjects Ansonville to Civil Penalty
Assessment. If not received by March 22, 2024, DWR will halt renewal of the subject permit and
return your application as "incomplete." This will subject Ansonville to further CPA for
discharging without a valid permit [see Section A. (1.)].
Public Notice. DWR has enclosed a renewal draft for your review and comment. Please review
this draft carefully to ensure your understanding of the limits and monitoring conditions, and to
correct errors, if any. Concurrent with this notification, the Division will solicit public comment
on this draft by publishing a notice in newspapers having circulation in the general Anson
County area, as required by the NPDES Program. We welcome your written comments on the
draft, but they are not mandatory.
NPDES standard conditions (Parts II, III, and IV) are part of this permit but are not included in
the draft (cover sheet, map, and Part I only). Standard conditions are the same as in your current
permit except that agency and division names have been updated. The latest version of these is
available at https://bit.ly/2BZ4xxx and can be viewed online or downloaded as a PDF file.

Renewal Changes. The Division understands that Ansonville has made no significant alterations
to treatment processes since last renewal. We have therefore made only minimal updates to your
permit. Division records show that you have successfully registered with the eDMR Program.
Following the mandatory 30-day Public Comment period, the Division will review all pertinent
comments, if any, and take appropriate action prior to issuing an NPDES permit final.
Again, permit renewal depends on Ansonville submitting the required analyses for Total Mercury
[using EPA Test Method 1631e]. If you have questions, please email me at
f ioe.corporona,deq.nc.gov1.

Monitoring Reports
1. Reportine Requirements [Supersedes Section D. (2.) and Section E. (5.) (a)l
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: hLtps:HdN.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

NPDES Permit NCO081825
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

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;

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 federalre ig ster gov/documents/2015/10/22/2015-24954/national-pollutant-discharge-

Electronic submissions must start by the dates listed in the "Reporting Requirements" section
above.
3. How to Request a Waiver from Electronic Reaortine
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.
