Dear Mr. Frye:

May 24, 1991
Subject: Permit No. WQ0004400
Stanly County Board Of Education
Stanfield Elementary School
Subsurface Disposal System
Stanly County
On January 2, 1991, the Division of Environmental Management issued Permit No.
WQ0004400 to the Stanly County Board of Education for the construction and operation of
wastewater subsurface disposal facilities to serve Stanfield Elementary School. On April 17,
1991, the Division received your letter describing your concerns about some of the conditions in
this permit. In order to alleviate any undue burden that may have been created by the subject
permit, the Division has evaluated the conditions in this permit and has prepared a modified permit
for the construction and operation of the subject 5400 GPD low pressure pipe wastewater
subsurface disposal system.
Condition 11.7 of Permit No. WQ0004400, which was issued on January 2, 1991,
required monthly purging and pressure testing on the subsurface laterals. This condition has now
been deleted. Condition III.2 of the modified permit has been reworded to require that the low
pressure lines be maintained as necessary in order to ensure that they remain free of obstructing
materials and that the pressure head on the laterals remains within the design specifications. The
highest and lowest laterals in each subfield must be checked (and adjusted as necessary) annually.
If adjustments are necessary to the highest and lowest laterals, th6 re- aiT nig laterals in that
subfield must also be checked and adjusted to the approved specifications- Additionally, the
inspection frequency on several other items specified in this condition has been relaxed. Condition
I1.6 has been reworded to require that the fields be routinely mowed and that the clippings be
periodically removed.
As you can see, the modified permit does not completely eliminate the necessity for
maintaining a method of checking the pressure heads on the laterals; however, the requirement is
now annually rather than monthly and it is possible that only the highest and lowest laterals on a
subfield would have to be checked. The burden is on the Stanly County Board of Education to
maintain the capability to check the pressure head as specified in the permit. One possibility
would be to place the end of each lateral in a box underground which can be easily located in some
manner (metal detector, etc.) or you may wish to leave the highest and lowest laterals flush with
the ground and obtain a locking lid.

This permit shall be effective from the date of issuance until December 31, 1995, shall
void Permit No. WQ0004400, which was issued on January 2, 1991, and shall be subject to the
conditions and limitations as specified therein. 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 modification are
unacceptable to you, you have the right to request an adjudicatory hearing upon written request
within 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, P.O. Drawer 27447, Raleigh, NC 27611-7447. Unless such
demands are made this permit shall be final and binding.
One set of approved pians and specifications was previously forwarded to you. If you
need additional information concerning this matter, please contact Mr. Randy Jones at 9191
733-5083.
