Subject: Minor modification to NPDES Permit
NCO023442—Moncure Plywood
Chatham County
Dear Mr. Cullen:
The Division has received and reviewed your request to make TRC monitoring optional in
the subject permit. You informed us that UV disinfection is in place at your facility, and that
mandatory chlorine sampling was no longer necessary as a result. The Division does not object to
your request to make the Total Residual Chlorine (TRC)limits and monitoring requirements
optional for these two facilities.
This permit modification is issued pursuant to the requirements of North Carolina General
Statute 143-215.1 and the Memorandum of Agreement between North Carolina and the U.S.
Environmental Protection Agency dated October 15, 2007 (or as subsequently amended). Insert
the attached pages into your permits and discard the old pages.
This modified permits include the following changes to the existing permits:
➢ Mandatory TRC monitoring with effluent limits has been made optional, to occur only
when chlorine is added to the treatment system.
➢ Text formatting changes have been made to show the newly-installed treatment
components, add regulatory citations and update the eDMR requirements.
If any parts, measurement frequencies or sampling requirements contained in this
modification are unacceptable to you, you have the right to an adjudicatory hearing upon written
request within thirty(30) days following receipt of this letter. This request must be in the form of
a written petition, conforming to Chapter 150B of the North Carolina General Statutes, and filed
with the Office of Administrative Hearings (6714 Mail Service Center, Raleigh, North Carolina
27699-6714). Unless such demand is made, this decision shall be final and binding.

This permit is not transferable except after notice to the Division. The Division may
require modification or revocation and reissuance of the permit. This permit does not affect the
legal requirements to obtain other permits which may be required by any other Federal, State, or
Local governmental regulation.
If you have any questions concerning these changes, please contact Charles H. Weaver at
[phone] or via e-mail [[e-mail]].

at this facility. The purpose of the additional monitoring will be to support water quality modeling efforts
within the Cape Fear River Basin and shall be consistent with a monitoring plan developed jointly by the
Division and affected stakeholders. In addition, the results of water quality modeling may require that
limits for Total Nitrogen and Total Phosphorus be imposed in this permit upon renewal.
A.(3) FACULTATIVE POND CLOSURE
[G.S. 143-215.1(b)]
The facultative pond treatment system (FPTS) will no longer be used for wastewater treatment. The
Permittee is required to submit a Facultative Pond Decommissioning Plan (Plan)that will describe how
the FPTS is scheduled to be decommissioned with residual solids removed.
Based on previous consensus between the Division and the Permittee, the Plan should show completion
of the final residual solid removal from the facultative pond and the final decommissioning of the FPTS
no later than 5 years from the startup date of the new 0.008 MGD treatment facility. The Plan shall"
demonstrate continued compliance with North Carolina and US EPA regulations and provide additional
details as follows:
1. Procedures and schedule for de-watering and eliminating/removing residual solids
2. Operation practices to be employed in the interim to address expected wastewater discharges and
treatment requirements
3. Any other anticipated actions to further neutralize solids or decommission the facultative pond
4. A copy of the facility modified Residual Management Plan
The following restrictions also apply to the FPTS:
➢ Per 15A NCAC 2T.0505 (d)the facultative pond shall not have less than 24 inches of freeboard.
➢ Any discharge from the facultative pond is subject to the effluent limits and monitoring frequencies
in Part I A. (1).
➢ The facultative pond residual inventory remains a major concern and should be managed
appropriately with no additional residual solids being added to the facultative pond.
A. (4) ELECTRONIC REPORTING OF MONITORING REPORTS
[G.S. 143-215.1(b)]
Federal regulations require electronic submittal of all discharge monitoring reports(DMRs)and program
reports and specify that, if a state does not establish a system to receive such submittals, then permittees

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. Until such time that the state's
eDMR application is compliant with EPA's Cross-Media Electronic Reporting Regulation
(CROMERR),permittees 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,

If a pernuttee 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

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.
