Persons reporting such occurrences by telephone shall also file a written report in
letter form within 15 days following first knowledge of the occurrence. This report
must outline the actions taken or proposed to be taken to ensure that the problem
does not recur.
IV. GROUNDWATER REQUIREMENTS
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 (see attached map). 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, If the water table occurs within the bedrock unit, then the
monitor wells must be constructed into this unit. The location and construction
details for these wells must be approved by the Asheville 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 February, June, and October 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 Total Coliforms (1/100 ml)
Total Suspended Solids
Volatile Organic Compounds - In October 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 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.
M.

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/i, this
concentration will be taken to represent the naturally occurring TOC concentration.
Any exeeedances 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 March, July, and November.
3. The Compliance Boundary delineated on the attached map 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 land application site, 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 plan upon its
approval by the Director.
4. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided.
5. No land application of wastewater shall take place when the seasonal high water
table is less than three feet below the surface of the land.
7

V. INSPECTIONS
The Permittee or his designee shall inspect the sludge storage, transport, 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 humann 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 by the Division of
Environmental Management or other permitting authority.
2. 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 Ieachate.
