Dear Mr. Temple:
On February 8, 1991, the Division of Environmental Management issued Permit No.
WQ0000855 to Data General Corporation for the continued operation of the subject wastewater
treatment and spray irrigation facilities. On March 4, 1991, the Division received a Petition for a
Contested Case Hearing which was filed by Data General Corporation with the Office of
Administrative Hearings. The objections which the petition identified have been reviewed and
evaluated by the Division and the subject permit is subsequently issued.
This permit shall be effective from the date of issuance until August 31, 1992, shall void
Permit No. WQ0000855, which was issued on February 8, 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.
As evidence of its acceptance of the draft permit transmitted to Data General Corporation
by letter dated April 3, 1991, Data General Corporation has submitted a Notice of Withdrawal of
Petition to the Office of Administrative Hearings; therefore, since this permit contains no
substantive changes from the previously accepted draft permit, this permit is final and binding.

Lead (0.05)
Chromium (0.05)
Zinc (5.0)
Volatile Organic Compounds*
*In November only by Method 1 or Method 2 below.
pH (6.5-8.5 standard units)
Chloride (250.0)
Cadmium (0.005)
Copper (1.0)
Water Level"
Method 1: Method 6230D ( Capillary - Column), "Standard Methods for
the Examination of Water and Wastewater", 17th edition, 1989
Method 2: Method 502.2 " Methods for the Determination of Organic
Compounds in Drinking Water", United States Environmental
Protection Agency - 60014-881039
**The measurement of water level must be made prior to sampling for the remaining
parameters.
The measuring points (top of well casing) of all monitoring wells shall be
surveyed relative to mean sea level (M.S.L.). The depth of the water in each well
shall be measured from the surveyed point on the top of the casing. The water level
elevations shall then be determined relative to M.S.L.
The numbers in parentheses represent the maximum allowable concentrations in
groundwater for the various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are given in parts per million.

If any volatile organic compounds are detected by method 6230D, or the equivalent
method 502.2, then EPA methods 604 and 611 must also be run to detect other
organic compounds which may be present. The results of all analysis specified in
the monitoring requirements, including 604 and 611 if required, must be submitted
simultaneously
The results of the sampling and analysis shall be sent to the N.C. Division of
Environmental Management on Form GW -59 (Compliance Monitoring Report
Form) every April, August, and December.

of Groundwater Quality Standards beyond the Compliance Boundary is subject to
penalty provisions applicable under General Statute 143-215.6(1)x. The sale of
property, by the Permittee, which is within or contiguous to the disposal system site
may alter the location of the Compliance Boundary.
For facilities permitted prior to December 30, 1983, the Compliance Boundary is
established at a distance of 500 feet from the lagoons and spray fields, or the
property boundary, whichever is less.
If the title to any property which may affect the location of the Compliance Boundary
is changed, the permittee shall notify the Division Director within 14 days. The
Director shall then establish a modified Compliance Boundary which will be done as
a modification to the Permit.
The REVIEW BOUNDARY for the disposal system is specified by regulations in 15
NCAC 2L, Groundwater Classifications and Standards. A REVIEW
BOUNDARY is established around disposal systems midway between the
Compliance Boundary and the perimeter of the waste disposal area. When the
concentration of any substance equals or exceeds the maximum allowable
concentration of that substance at the REVIEW BOUNDARY, as determined by
monitoring, the permittee shall either (i) demonstrate, through predictive calculations
or modeling, that natural site conditions, facility design and operational controls will
prevent a violation of standards at the Compliance Boundary; or, (ii) submit a plan
for the alteration of existing site conditions, facility design or operational controls
that will prevent a violation of standards at the Compliance Boundary, and
implement that plan upon its approval by the Director.
Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
V. INSPECTIONS
Adequate inspection, maintenance, and cleaning shall be provided by the Permittee to
insure proper operation of the subject facilities.
