Persons reporting such occurrences by telephone shall also file a written report in a
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
Prior to beginning waste disposal operations, two (2) monitor wells, one (1)
upgradient and one (1) downgradient, must be installed to monitor groundwater
quality. The wells 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.
The location and construction details for these wells must be approved by the
Mooresville 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:
TOC - pH ( 6.5-8.5 standard units)
Total Phosphorus TDS (500.0)
Water Level Total Coliforms (1/100 ml)
Lead (0.05) Total Suspended Solids
Cadmium (0.005) Oil & Grease
Chromium (0.05)
EPA Method 624 to include analysis for ethylene glycol monobutyl ether
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/1 are detected in any downgradient
monitoring well, additional sampling and analysis must be conducted to identify
the "microorganisms, natural organic and/or synthetic organic compounds"
comprising this TOC concentration. If the TOC concentration as measured in
the back ound monitor well exceeds 10 mg/1, 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.
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 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 edge of the 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 map 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. An additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
V. INSPECTIONS
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 permitting authority.

DEFINITIONS
(I)Activated Carbon Beds. A physicallchomical method for roducing solubio organic material from
wastewater effluent; the column -type beds used in this method will have a flow rate varying from two
to eight gallons per minute per square foot and may be either upflow or downflow carbon beds. Carbon
may or may not be regenerated on the wastewater treatment plant site.
(2)Aorated Lagoons. A basin in which all solids are maintained )n suspension and by which biological
oxidation or organic matter is reduced Through arliffcialiy accelerated transfer of oxygen on a flow-
