This permit shall be effective from the date of issuance until August 31, 2010, shall void Permit
No. WQ0009896 issued September 30, 2005, and shall be subject to the conditions and limitations as
specified therein. Please pay particular attention to the monitoring requirements listed in Attachments A

collecting and maintaining the required operational information shall result in future compliance
problems.
Please note the following permit conditions are new since the last permit issuance:
➢ Condition I1.7. - A permit modification is required prior to any sale or transfer of the property
if a compliance boundary is affected.
➢ Condition 11.8 - With limited exceptions, no wells are allowed within the compliance

ENVIRONMENTAL MANAGEMENT COMMISSION
DEPARTMENT OF ENVIRONMENT AND NATURAL RESOURCES
RALEIGH
WASTEWATER IRRIGATION SYSTEM PERMIT
In accordance with the provisions of Article 21 of Chapter 143, General Statutes of North Carolina as
amended, and other applicable Laws, Rules and Regulations
PERMISSION IS HEREBY GRANTED TO
North Carolina State University
Wake County
FOR THE
continued operation of a 1000 gallon per day (GPD) wastewater treatment and wastewater irrigation
facility consisting of a 30,000 gallon lined aerobic lagoon and a 29,025 square foot spray irrigation field
to serve North Carolina State University's Animal Waste Management Facility and treat a waste stream
of 154 gallons per day from a proposed cellulose -to -ethanol pilot plant, with no discharge of wastes to
surface waters, pursuant to the application received July 10, 2009 and in conformity with the project
plans, specifications, and other supporting data subsequently filed and approved by the Department of
Environment and Natural Resources and considered a part of this permit.
This permit shall be effective from the date of issuance until August 31, 2010, shall void Permit No.
WQ0009896 issued September 30, 2005 and shall be subject to the following specified conditions and
limitations:
I. SCHEDULES
I. No later than six months prior to the expiration of this permit, the Permittee shall request renewal of
this permit on official Division forms. Upon receipt of the request, the Division will review the
adequacy of the facilities described therein, and if warranted, will renew the permit for such period of
time and under such conditions and limitations as it may deem appropriate. Please note Rule 15A
NCAC 02T .0105(d) requires an updated site map to be submitted with the permit renewal
application.
II. PERFORMANCE STANDARDS
The subject non -discharge facilities shall be effectively maintained and operated at all times so there
is no discharge to surface waters, nor any contravention of groundwater or surface water standards.
In the event the facilities fail to perform satisfactorily, including the creation of nuisance conditions
due to improper operation and maintenance, or failure of the irrigation areas to adequately assimilate
the effluent, the Permittee shall take immediate corrective actions including Division required actions,
such as the construction of additional or replacement wastewater treatment or disposal facilities.
2. This permit shall not relieve the Permittee of their responsibility for damages to groundwater or
surface water resulting from the operation of this facility.

any sale or transfer of property affecting a compliance boundary.
8. In accordance with 15A NCAC 02L .0107(d), no wells, excluding Division approved monitoring
wells, shall be constructed within the compliance boundary except as provided for in 15A NCAC 02L
.0107(g).
