J1r, :`1
1. Prior to beginning waste disposal operations, three (3) monitor wells, one (1)
upgradient and two (2) downgradient, shall be installed to monitor groundwater
quality. The well(s) 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 shall be
approved by the Washington Regional Office, from which a well construction
permit must be obtained.
2. The monitor wells must be sampled initially after construction (and prior to waste
disposal operations) and thereafter every April, August, and December for the
following parameters:
NO3 (10.0) TDS (500.0)
TOC pH ( 6.5-8.5 standard units)
Ammonia Nitrogen Chlorides (250.0)
Water Level Fecal Coliforms (1/100 ml)
Total Suspended Solids
Volatile Organic Compounds - In December 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
grDundwater for the various analytical parameters, as specified in 15 NCAC 2L
[Groundwater Classifications and Standards]. Unless otherwise noted, the
concentrations are given in milligrams per liter.

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 TQC 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 TQC 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 May, September, and January.
3. "The C�mgliance 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 nitrification field, 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 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 pian 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. INSPECTIONS
I . 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 permitting authority.
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.
