Wastewater Surface Irrigation
Gates County
Dear Ms. Slone:
In accordance with your permit modification request received July 19, 2007 through Stroud
Engineering, we are forwarding herewith Permit No. WQ0006932, dated August 7, 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 III.
This permit shall be effective from the date of issuance until May 31, 2012, shall void Permit No.
WQ0006932 issued June 27, 2007, 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 W.3.). Please also note that the
maximum annual application rate on all fields has been lowered from 26.0 inches per year to the rate of
8.27 inches per year (Attachment B) in all fields, and that freeboard in the storage/treatment lagoon is to
be recorded weekly (Permit Condition IV.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 concerning this matter, plea e contact David Goodrich at
[phone] or [e-mail].

constructed within the compliance boundary except as provided by ISA NCAC 02L .0107(g).
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.

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-

2. The measurement of water levels shall be made prior to purging the wells. The depth to water in each well shall be measured from the surveyed point on the top
of the casing. The measurement of pH shall be made after purging and prior to sampling for the remaining parameters.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the relative elevation of the measuring point for each monitoring well.
The measuring points (top of casing) of all monitoring wells shall be surveyed relative to a common datum.
4. If TOC concentrations greater than 10 mgll are detected in any downgradient monitoring well, additional sampling and analysis must be conducted to identify
the individual constituents comprising this TOC concentration. If the TOC concentration as measured in the background monitor well exceeds 10 mg/l, this
concentration will be taken to represent the naturally occurring TOG 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.
