pressure pipe subsurface wastewater disposal system. This reissuance is to correct a
typographical error in Permit WQ0004395 issued February 28, 1991. On page four (4) item IV
(2), the February 28, 1991 permit reads " the three (1) existing..."; this corrected permit issued
May 14, 1991 reads "The one (1) existing...".
This permit shall be effective from the date of issuance until January 31, 1996, shall
thereby void Permit No. WQ0004395 issued February 28, 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 are unacceptable to you,
you have the right to request an adjudicatory hearing upon written request within 30 days
following the issuance of Permit WQ0004395 issued February 28, 1991. 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

IV. GROUNDWATERREQUIREMENTS
Within 90 days of permit renewal issuance, monitor well 1 A shall be permanently
abandoned and a replacement well (MW -1B) shall be installed at the location
indicated on the attached map. The well shall be constructed such that the water
level in the well is never above or below the screened (open) portion of the well at
any time during the year. However, the exact location and construction details for
these wells must be approved by the Raleigh Regional Office, from which a well
construction permit must be obtained.
2. The one (1) existing monitor well (MW -2) and the new monitor well (MW -1B)
shall be sampled every March, July, and November for the following parameters:
NO3 (10.0)
TOC
Ammonia Nitrogen
Water Level
Total Suspended Solids
TDS (500.0)
pH ( 6.5-8.5 standard units)
Chlorides (250.0)
Fecal Coliforms (1/100 ml)
Volatile Organic Compounds - In November only (by Method 1 or Method
2 below)
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.
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 TOC concentrations greater than 10 mg/l 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.
0

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.
3. The Compliance Boundary 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 lesser 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 BOUNDARY delineated on the attached site plan 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.
4. Any additional groundwater quality monitoring as deemed necessary by the
Division of Environmental Management shall be provided.
V. INSPECTIQNS
1. Adequate inspection, maintenance, and cleaning shall be provided by the Permittee
to insure proper operation of the subject facilities.
2. The Permittee or his designee shall inspect the wastewater treatment and disposal
facilities to prevent malfunctions and deterioration, operator errors and discharges
which may cause or lead to the release of wastes to the environment, a threat to
human health, or a nuisance. The Permittee shall keep an inspection log or
summary including at least the date and time of inspection, observations made, and
any maintenance, repairs, or corrective actions taken by the Permittee. This log of
inspections shall be maintained by the Permittee for a period of three years from the
date of the inspection and shall be made available upon request to the Division of
Environmental Management or other pemnitting authority.
5

3. Any duly authorized officer, employee, or representative of the Division of
Environmental Management may, upon presentation of credentials, enter and
inspect any property, premises or place on or related to the disposal site and facility
at any reasonable time for the purpose of determining compliance with this permit;
may inspect or copy any records that must be kept under the terms and conditions
of this permit; or may obtain samples of groundwater, surface water, or leachate.
V1. GENERAL CONDITIONS
1. This permit shall become voidable unless the facilities are constructed in accordance
with the conditions of this permit, the approved plans, specifications and other
supporting data.
2. This permit is effective only with respect to the nature and volume of wastes
described in the application and other supporting data.
3. This permit is not transferable. In the event there is desire for the facilities to
change ownership, or there is a name change of the Permittee, a formal permit
request must be submitted to the Division of Environmental Management
accompanied by an application fee, documentation from the parties involved, and
other supporting materials as may be appropriate. The approval of this request will
be considered on its merits and may or may not be approved.
4. Prior to any transfer of this land, a notice shall be given to the new owner that gives
full details of the materials applied or incorporated at this site.
