Subject: NPDES Minor Permit Modification
Permit NCO089478
Camp Watia WWTP
Swain County
Class II
In accordance with your request to provide an intermediate 0.006 MGD limitation page in your
NPDES permit to accommodate your December 12, 2014 Authorization to Construct application for
the first phase of construction for 0.006 MGD treatment capacity, a minor permit modification is being
issued. As we discussed, except for the permitted flow both limitation pages, 0.006 MGD and 0.012
MGD have the identical limits and monitoring requirements. To expand to 0.012 MGD will require
you to obtain an Authorization to Construct permit for the 0.012 MGD expanded flow. Additional
technical corrections were made to narratives and formatting where warranted.
Please insert the attached minor modification pages in your existing permit and discard any
pages that are duplicated by the minor modification pages.
Please note that 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 the Division of Water Resources
or any other Federal, State, or Local governmental permits that may be required.

A. (3.) ELECTRONIC REPORTING - DISCHARGE MONITORING REPORTS
Proposed federal regulations require electronic submittal of all discharge monitoring reports (DMRs)
and specify that, if a state does not establish a system to receive such submittals, then Permittees must
submit DMRs electronically to the Environmental Protection Agency (EPA). The Division anticipates
that these regulations will be adopted and will begin implementing in 2013.
NOTE: This special condition supplements or supersedes the following sections within Part II of this
permit (Standard Conditions for NPDES Permits):
• Section B. (11.)
• Section D. (2.)
• Section D. (6.)
• Section E. (5.)
Signatory Requirements
Reporting

Monitoring Reports
1. Reporting [Supersedes Part H, Section D. (2.) and Section E. (5.) (a)]
Beginning no later than 270 days from the effective date of this permit, 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. 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,
signing, and submitting one signed original and a copy of the computer printed eDMR to the
following address:
NC DENR / DWR / Information Processing Unit
ATTENTION: Central Files / eDMR
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.

ADDENDUM — FACT SHEET NCO089478 Camp Watia WWTP — May. 19 2015
An Authorization to Construct (A to C) application was received 12/12/14 for yet- to- be built domestic
treatment plant for NCO089478 Camp Watia WWTP. The NPDES permit provided a limitation page for
0.012 MGD but the A to C application was for a phase I initial plant operation/design of 0.006 MGD. To
proceed with the A to C permit, a 0.006 MGD limitation page was required in the NPDES permit. After
discussions with the permittee, it was agreed a minor NPDES permit modification would be issued
adding the intermediate 0.006 MGD limitation page with identical limits and monitoring requirements,
except for the flow limit, as stated for the 0.012 MGD limitation page. Because of the addition of the
0.006 MGD flow page, to expand to 0.012 MGD will require the permittee to obtain an A to C permit and
submit a signed Engineer's Certificate for the expansion. Various technical corrections to narratives and
formatting were made wh a required.
