Noncompliance Notification:
The Permittee shall report by telephone to the Raleigh Regional Office, telephone
no. 919/ 733-2314, as soon as possible, but in no case more than 24 hours or on
the next working day following the occurrence or first knowledge of the occurrence
of any of the following:
a. Any occurrence at the wastewater treatment facility which results in the
treatment of significant amounts of wastes which are abnormal in quantity
or characteristic, such as the dumping of the contents of a basin or tank; the
known passage of a slug of hazardous substance through the facility; or any
other unusual circumstances.
b. Any process unit failure, due to known or unknown reasons, that render the
facility incapable of adequate wastewater treatment such as mechanical or
electrical failures of pumps, aerators, compressors, etc.
C. Any failure of a pumping station, sewer line, or treatment facility resulting
in a by-pass of all or any portion of the influent to such station or facility.
d. Any time that self-monitoring information indicates that the facility has gone
out of compliance with its permit limitations.
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.
GROUNDWATER REQUIREMENTS
1. The two (2) existing monitor wells must be sampled every March, July, and
November for the following parameters:
TDS (500.0) pH ( 6.5-8.5 standard units)
Oil & Grease Water Level
MBAS Orthophosphate
Total Petroleum Hydrocarbons (EPA Method 418.1)
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.
3

The numbers in parentheses represent the maximum allowable concentrations in
groundwater for the various analytical parameters, as specified in 15 NCAC 2L
LGroundwater 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
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.
2. The Compliance Boundary 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 subsurface disposal 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 RE V IE W
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.
Any additional groundwater quality monitoring as deemed necessary by the
Division of Environmental Management shall be provided.
4. Oil drained from engine crankcases or degreasing solvents wastes shall not be
discharged into the disposal system.
