Dear Ms. Slone:
In accordance with your permit renewal request received October 4, 2005, we are forwarding
herewith Permit No. WQ0006932, dated June 27, 2007, to Professional Laboratory & Research Services,
Inc. for the continued operation of the subject wastewater treatment and surface irrigation facilities, and
the construction of Field 111.
This permit shall be effective from the date of issuance until May 31, 2012, shall void Permit No.
WQ0006932 issued December 16, 2005, and shall be subject to the conditions and limitations as specified
therein. Please note that there are many new conditions. The nitrogen loading of the spray fields has been
reduced from 400 pounds per acre per year to 300 pounds per acre per year to be more reflective of the
Realistic Yield Estimates (RYES) (Attachment B), and the measurement, recording, and reporting of
influent flow and recycled flow are both required (Permit Condition IV.3.). Please also note that the
maximum annual application rate has been lowered from 26.0 inches per year to the previously permitted
rate of 7.59 inches per year (Attachment B), and that freeboard in the storage/treatment lagoon is to be
recorded weekly (Permit Condition N.6.). Groundwater monitoring requirements are listed in Attachment
C. Please pay particular attention to the monitoring requirements in this permit. Failure to establish an
adequate system for collecting and maintaining the required operational information will result in future
compliance problems.
If any parts, requirements, or limitations contained in this permit are unacceptable, you have the
right to request an adjudicatory hearing upon written request within thirty (30) days following receipt of
this permit. This request must be in the form of a written petition, conforming to Chapter 150B of the
North Carolina General Statutes, and filed with the Office of Administrative Hearings, 6714 Mail Service
Center, Raleigh., NC 27699-6714. Unless such demands are made this permit shall be final and binding.
If you need additional information conceniing this matter, please contact David Goodrich at
[phone] or [e-mail].

constructed within the compliance boundary except as provided by 15A NCAC 02L A 107(g).
8. The review boundary is established. around the disposal systems midway between the compliance
boundary and the perimeter of the waste disposal area. Any exceedance of standards at the review
boundary shall require action in accordance with 15A NCAC 02L .0106.
9. The facilities permitted herein must be constructed according to the following setbacks:
a. The setbacks for Irrigation sites shall be as follows (all distances in feet):
i. Any habitable residence or place of public assembly under separate ownership: 400
ii. Any property line: 150

amounts of wastes which are abnormal in quantity or characteristic, such as the dumping of the
contents of a sludge digester; the known passage of a slug of hazardous substance through the
facility; or any other unusual circumstances including ponding in the irrigation field or runoff
from the irrigation fields.

credentials, enter and inspect any property, premises or place on or related to the disposal site or
facility at any reasonable time for the purpose of determining compliance with this permit; may
inspect or copy any records that must be maintained under the terms and conditions of this permit,
and may obtain samples of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
1. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee
to an enforcement action by the Division in accordance with North Carolina General Statute 143-

concentration will be taken to represent the naturally occurring TOC concentration. Any exceedances of this naturally occurring TOC concentration
in the downgradient wells shall be subject to the additional sampling and analysis as described above-
5. Monitoring wells shall be reported consistent with the nomenclature and location information provided in Figure 2 and this attachment.
