Wastewater Spray Irrigation
Wayne County
Dear Mr. Davis:
On August 16, 1991, the Division of Environmental Management issued Permit No. WQ0004728
to the Town of Fremont for the continued operation of the subject wastewater treatment and spray
irrigation facilities. On September 17, 1991, the Division received a copy of a "Petition for Contested
Case Hearing," which the Town of Fremont filed with the Office of Administrative Hearings. The petition
requests that the buffers which are specified in the August 16, 1991, permit be modified to match those
which were in existence at the time that Permit No. 6144 was originally issued for the construction and
operation of the subject wastewater treatment and spray irrigation facilities. The Division has reviewed
this request and has modified condition 1.5 to reflect language which is acceptable to you, as you
discussed during your telephone conversation with Mr. Randy Jones of my staff on October 7, 1991.
This permit shall be final and effective from the date of issuance until July 31, 1996, shall void
Permit No. WQ0004728, which was issued on August 16, 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

l . The four (4) existing monitor wells shall be sampled every March, July, and November for
the following parameters:
NO3 (10.0) TDS (500.0)
TOC pH ( 6.5-8.5 standard units)
Ammonia Nitrogen Chloride (250.0)
Water Level Total Coliforms (1/100 ml)
Cadmium (0.005) Total Suspended Solids
Chromium (0.05) Lead (0.05)
Nickel Cyanide
Volatile Organic Compounds - In November only ( by Method 1 or Method 2
below)
Ell

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.
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 -
600/4-88/039
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 to
provide relative elevations of the measuring point for each of the monitoring wells. The
depth of water in each well shall be measured from the surveyed point on the top of the
casing.
If TOC concentrations greater than 10 mg/1 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 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.
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
2. The Compliance Boundary for the disposal system is specified by regulations in 15 NCAC
2L, Classifications and Water Quality Standards applicable to the groundwater of North
Carolina. An exceedance of Groundwater Quality Standards beyond the Compliance
Boundary is subject to penalty provisions applicable under General. Statute 143-215.6(1)a.
The sale of property, by the Permittee, which is within or contiguous to the disposal
system site may alter location of the Compliance Boundary.
For facilities permitted prior to December 30, 1983, the Compliance Boundary is
established at the lesser of 500 feet from the stabilization lagoons and the 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.
5

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.
3. Any additional groundwater quality monitoring, as deemed necessary by the Division, shall
be provided.
