326 Old Charlotte Hwy, Rockingham
Richmond County
Dear Mr. Land:
Based on your renewal request for the subject site(received October 25, 2018 from Lee P. Butler
WTP ORC),the Division of Water Resources (DWR or the Division)hereby transmits this draft for
your review and comment. Please review it 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 Richmond County area, as
required by the NPDES Program. Please provide your written comments, if any,to DENR/DWR/
NPDES Program no later August 28,2019 (approximately 30 days after receiving this document).
Your written comments are welcome but are not mandatory.
Because this facility does not currently discharge [effluent routed to the Smith Energy Complex
for reuse as cooling water], we hereby instruct you to notify the Fayetteville Regional Office
(FRO)if and when you chose to resume discharging to waters of the State(see Supplement to
Permit Cover Sheet). Please contact the Fayetteville Regional office no later than 30 days prior
to beginning discharge. The Division however has no record of your request for a DMR
Reporting Waiver.
Renewal Changes. The Division understands that you have 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. Please
be reminded that until the state's eDMR application is approved compliant with EPA's Cross-Media

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 intern t. Until such time that the state's eDMR application is
compliant with EPA's Cross-Media ElectroniF Reporting Regulation(CROMERR),pennittees will be
required to submit all discharge monitoring data to the state electronically using eDMR and will be required
to complete the eDMR submission by printing,signing,and submitting one signed original and a copy of the
computer printed eDMR to the following address:
NC DENR/Division of Water Resources/Water Quality Permitting Section
ATTENTION: Central Files
1617 Mail Service Center
Raleigh,North Carolina 27699-1617
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 mailing address above. 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.

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:
http://www2.epa.gov/compliance/final-national-pollutant- a�ge-eliminatio system-npdes-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:
