Dee Freeman
Secretary
In accordance with your permit major modification request received June 19, 2012, and
subsequent additional information received October 15, 2012, we are forwarding herewith Permit No.
WQ0002161 dated December 12, 2012, to Carolina Friends School for the construction and operation of
the subject wastewater treatment and drip irrigation facilities.
The modifications to the subject permit are as follows:
➢ Removal of all references, conditions and monitoring requirements related to the
conjunctive reclaimed water facilities;
➢ Removal of aeration treatment plant, surface storage lagoon and spray irrigation;
➢ Addition of media pod treatment units, underground dosing and storage tanks, pumping
and control systems, and an ultraviolet disinfection system;
➢ Addition of a multi zone drip irrigation field;
➢ Addition of a septic tank to serve the existing Lower School buildings;
➢ Addition of a system to collect backwash water from the sand filters that serve the
school's water supply well and add to the waste stream.
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. In addition, Session Law 2010-177
extended the Act by another year. Permit No. WQ0002161 falls within the scope of this Act and is
therefore being extended until February 29, 2016. 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 February 29, 2016, shall void Permit
No. WQ0002161 issued December 5, 2008 and shall be subject to the conditions and limitations as

Any duly authorized Division representative may, upon presentation of credentials, enter and
inspect any property, premises or place on or related to the wastewater treatment and
irrigation facilities permitted herein at any reasonable time for the purpose of determining
compliance with this permit; may inspect or copy any records required to be maintained
under the terms and conditions of this permit, and may collect groundwater, surface water or
leachate samples.
VI. GENERAL CONDITIONS
Failure to comply with the conditions and limitations contained herein may subject the
Permittee to an enforcement action by the Division in accordance with North Carolina
General Statutes 143-215.6A to 143-215.6C.
2. This permit shall become voidable if the permitted facilities are not constructed in accordance
with the conditions of this permit, the Division approved plans and specifications, and other
supporting documentation.
3. This permit is effective only with respect to the nature and volume of wastes described in the
permit application, Division approved plans and specifications, and other supporting
documentation. No variances to applicable rules governing the construction or operation of
the permitted facilities are granted, unless specifically requested and approved in this permit
pursuant to 15A NCAC 02T .0105(n).
4. In accordance with 15A NCAC 02T .0114(f) and pursuant to the flow reduction request
received March 8, 2011 and approved April 25, 2011, the Division accepts the data -based
design flow rate of 10 gallons per day per student (GPD/student) for the users served by this
facility. Regardless of the adjusted daily wastewater design flow rate, at no time shall
wastewater flows exceed the limits defined in this permit for the subject facility, or exceed
the sewer capacity downstream of any new sewer extension or service connection(s).
The Permittee shall report the actual (i.e., measured) monthly average amount of wastewater
flow contributed per unit (GPD/student) for the 12 months prior to permit renewal. If any of
these actual monthly averages are within 20% of the 5500 gallons per day (or 4,400 gallons
per day), the Permittee shall re-evaluate the approved value using the methodology applied to
determine the approved flow rate of 10 GPD/student and submit this information within 18
months of February 29, 2016. The Division may change the daily wastewater design flow
rate for connections to the system at that time, and upon each renewal cycle, pending an
evaluation of the submitted flow information.
5. In accordance with 15A NCAC 02T .0114(f)(4), the Permittee shall retain the Division's
written approval of any authorized adjusted daily design flow rate for the life of the facility,
and shall transfer said written approval to any future Permittee.
The issuance of this permit does not exempt the Permittee from complying with any and all
statutes, rules, regulations, or ordinances, which may be imposed by other jurisdictional
government agencies (e.g., local, state, and federal). Of particular concern to the Division are
applicable river buffer rules in 15A NCAC 02B .0200; erosion and sedimentation control
requirements in 15A NCAC Chapter 4 and under the Division's General Permit NCG010000;
any requirements pertaining to wetlands under 15A NCAC 02B .0200 and 02H .0500; and
documentation of compliance with Article 21 Part 6 of Chapter 143 of the General Statutes.
