The Permittee shall report by telephone to the Asheville Regional Office,
telephone no. 7041251-6208, 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 sludge digester, 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 directly to receiving waters without treatment 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.
The three (3) existing monitor wells (P86a5, P86b2, and P86b3) shall continually be
sampled every March, July, and November for the following parameters:
TOC (10.0)
Ammonia Nitrogen
Phenol
Chromium (0.05)
Total Suspended Solids
MBAS
Copper (1.0)
Sodium
TDS (500.0)
pH (6.5-8.6 standard units)
Arsenic (0.05)
Water Level
SO4 (250.0
Cadmium (0.005)
Lead (0.05)
Mercury (0.0011)
*Volatile Organic Compounds - In November only ( by Method 1 or Method
2 below)
*After the submittal of volatile organic compounds sampling results for two
annual reporting periods, Rockwell International Corporation may make a
formal permit modification request to the Division to have the requirement for
sampling for volatile organic compounds deleted from the permit. Such a
request, if made, would be considered and acted upon by the Division in light
of the sampling results for volatile organic compounds submitted by Rockwell
for all preceding annual reporting periods, relevant statutory and regulatory
requirements, and other appropriate criteria.
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.
N

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 milligrams per liter.
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/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 Cb-mpliance BoundM 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 prior to December 30, 1983, the Compliance Boundary is
established at a distance of 500 feet from the lagoon and spray field, or the property
boundary, whichever is less.
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.

3. Any additional groundwater quality monitoring, as deemed necessary by the
Division, shall be provided.
1. Adequate inspection, maintenance, and cleaning small 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.
