Please note that on August 5, 2009, Session Law 2009-406, entitled "An Act to Extend Certain
Government Approvals Affecting the Development of Real Property Within the State," was enacted by
the General Assembly and signed into law. The Act, known as the Permit Extension Act of 2009, extends
the expiration date of certain government approvals and permits. As part of the 2010 legislative session,
(S.L. 2010-177) HB 683 - Permit Extensions extended the Act by another year. Non -discharge permit
WQ0018489 has therefore been extended until .tune 30, 2014. Per your permit, a renewal application
must still be submitted six months in advance of the extended expiration date.
This permit shall be effective from the date of issuance until June 30, 2014, shall void Permit No.
WQ0018489 issued January 31, 2008, and shall be subject to the conditions and Iimitations as specified
therein. Please pay particular attention to the monitoring requirements listed in Attachments A and B.
Failure to establish an adequate system for collecting and maintaining the required operational
information shall result in fixture compliance problems.
Please pay special attention to the following items which have changed since the previous
permit issuance:
➢ Condition I, l .- requires a completed engineering certification to be submitted prior to
operation of the new 500,000-gallon reclaimed water storage tank.
➢ Condition Mg. — the cross connection control requirement has been revised to be consistent
with Session Law 2011-218 (House Bill 388).
➢ Condition M.1. —states that the Permittee shall maintain an Operation and Maintenance Plan
pursuant to 15A NCAC 02U.0801.
➢ Condition M.2. — requires that the Operation and Maintenance Plan include a plan for
monitoring reclaimed water quality within the distribution system at locations determined by
the Permittee to be representative of the reclaimed water delivered to users. Please note that
the distribution system monitoring results do not need to be reported on form NDMR.
Records of these monitoring results shall be kept by the Permittee and made available to the
Division upon request.
➢ Attachment A -- PPI 001 contains reporting requirements for reclaimed water utilized via the
distribution system. PPI 002 requires reporting of flows distributed through bulk fill
activities. Please note that one NDMR form should be submitted for PPI 001 and one NDMR
form should be submitted for PPI 002. For your convenience an electronic copy of your
facility's NDMR forms will be available for download at the following web address:
htt :// ortal.ncdenr.oro/web/w is s/lau/re ortinR.
Attachment B — contains allowable uses and requirements for bulk distribution of reclaimed
water.

result in overspray, over application, or runoff from the location of application or point of
use; determining that adequate notification is provided to employees and the public regarding
reclaimed water uses that are industrial in nature; as well as disseminating educational
material regarding use of the reclaimed water system and compliance with all applicable local
ordinances.

commercial, industrial, and institutional user connected to the reclaimed water distribution
system once per permit cycle. The minimum tasks associated with the follow-up inspection
shall be the same as that associated with the connection inspection.
d. A compliance and enforcement program that would require the Permittee to ensure
compliance with the conditions of this permit as well as all applicable local ordinances. The
program shall include a component to address non-compliance with respect to the use of the
reclaimed water system by each type of user (i.e., residential, commercial, industrial, and
