Orange County
In accordance with your permit renewal request received August 7, 2015, we are forwarding
herewith Permit No. WQ0002161 dated May 6, 2016, to The Carolina Friends School for the continued
operation of the subject wastewater treatment and irrigation facilities.
This permit shall be effective from the date of issuance until April 30, 2021, shall void Permit No.

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 future compliance problems.
Please note the following permit conditions have been removed since the last permit issuance
dated December 12, 2012:
➢ Old Condition I.1. — This condition has been removed because the Engineering Certification
was received August 27, 2014.
➢ Old Condition 1.2. — This condition's requirements have been met by Permittee.
➢ Old Condition I.3. — This condition has been removed because the start-up inspection for the
installed facilities has been conducted.
➢ Old Condition II1.12. — This condition has been removed because there is no longer a storage
lagoon associated with this facility.
Please note the following attachments have been modified since the last permit issuance dated
December 12, 2012:
➢ Attachment A — PPI 001, PPI 004 and PPI 006 have been combined under PPI 001. All sample
types are grab. Monitoring for Chloride and Total Dissolved Solids is no longer required,
however, monitoring for Total Kjeldahl, Phosphorus and Total Nitrogen have been added the

and may collect groundwater, surface water or leachate samples. [G.S. 143-21.5.3(a)(2)]
VI. GENERAL CONDITIONS
1_ 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. [G.S. 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. [ 15A NCAC 02T .0110]
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).
[G.S. 143-21.5.1 ]
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. [ 15A NCAC
02T .0114(fl]
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. [ 15A NCAC 02T .0114(f)]

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 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. [15A NCAC 02T .0105(c)(6)]

Director, in whole or part for the requirements listed in 15A NCAC 02T .0110. [ 15A NCAC 02T .0110]
11. Unless the Division Director grants a variance, expansion of the permitted facilities contained herein
shall not be granted if the Permittee exemplifies any of the criteria in 15A NCAC 02T .0120(b). [15A
NCAC 02T .0120]
12. The Permittee shall pay the annual fee within 30 days after being billed by the Division. Failure to pay
the annual fee accordingly shall be cause for the Division to revoke this permit. [15A NCAC 02T
