Dear Mr. Lord:
In accordance with your application received June 26, 1991, and a February 11, 1992
amendment request from the Division's Wilmington Regional Office we are forwarding herewith
Permit No. WQ0002100 as amended, dated April 28, 1992, to Pender County Board of
Commissioners for the continued operation of a 665 GPD wastewater treatment facility with a low
pressure pipe subsurface wastewater disposal system. This permit amends condition III.3
changing sampling requirements for BOD5 and Total Suspended Solids from composite sampling
to grab sampling, eliminates monitoring for residual chlorine, and changes effluent flow
monitoring to daily total flow measurement.
This permit shall be effective from the date of issuance until July 31, 1996, 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.
Issuance of this permit hereby voids Permit No. WQ0002100 issued August 26, 1991.
If any parts, requirements, or limitations contained in this permit are unacceptable to you,
you have the right to request an adjudicatory hearing upon written request within 60 days
following receipt of this permit. This request must be in the form of a written petition,
conforming to Chapter 150B of 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.

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/i 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 November.
2. The Compliance Bound= delineated on the attached site plan 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 on or after December 30, 1983, the Compliance Boundary is
established at the Iesser of 250 feet from the perimeter of the waste disposal area, or
50 feet within the property boundary.
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 BOUND
ARY delineated on the attached site map for the disposal
system is specified by regulations in 1.5 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.
