I
The Permittee shall report by telephone to the Washington Regional Office, telephone
number 919/946-6481, 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 with the land application program which results in the land
application of significant amounts of wastes which are abnormal in quantity or
characteristic.
b. Any failure of the land application program resulting in a release of sludge material
to receiving waters.
c. Any time that self -monitoring information indicates that the facility has gone out of
compliance with the conditions and limitations of this permit or the parameters on
which the system was designed.
d. Any process unit failure, due to known or unknown reasons, that renders the
facility incapable of adequate sludge treatment.
e. Any spillage or discharge from a vehicle or piping system transporting sludge to the
application site.
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.
RIMILIKIny-fAIMA"I
1. The three (3) existing monitor wells must be sampled every March, July, and November
for the following parameters:
NO3
TOC
Ammonia Nitrogen
Water Level
Total Suspended Solids
Volatile Organic Compounds -
pH
Chlorides
Fecal Coliforms
In November anly (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. These
elevations shall be provided to the Regional Hydrogeologist within 60 days after well
construction. The depth of water in each well shall be measured from the surveyed point
on the top of the casing.
C

If TOC concentrations greater than 10 mg/i 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 Complian�Q $Qundary for the disposal system is specified by regulations in 15A
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 143-215.6A.
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 sites, 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 BOJNDARY for the disposal system is specified by regulations in 15A
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 groundwater quality monitoring, as deemed necessary by the Division of
Environmental Management, shall be provided.
4. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below land surface.

V . INSPECTIONS
1. 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 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 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 leachate.
VI. GENERAL CONDITIONS
1. This permit shall become voidable unless the land application activities are carried out in
accordance with the conditions of this permit and in the manner approved by this Division.
2. This permit is effective only with respect to the nature and volume of wastes described in
the application and other supporting data.
3. This permit is not transferable. In the event there is a desire for the facilities to change
ownership or a name change of the Permittee, a formal permit request must be. submitted to
the Division of Environmental Management accompanied by an application fee,
documentation from the parties involved, and other supporting materials as may be
appropriate. The approval of this request will be considered on its merits and may or may
not be approved.
4. Prior to any transfer of this Iand, a notice shall be given to the new owner that gives full
details of the materials applied or incorporated at this site.
5. Failure to abide by the conditions and limitations contained in this permit may sohject the
Permittee to an enforcement action by the Division of Environmental Mariagennent in
accordance with North Carolina General Statute 143-215.6A to 143-215.6C.
6. The annual administering and compliance fee must be paid by the Permittee within thirty
(30) days after being billed by the Division. Failure to pay the fee accordingly may cause
the Division to initiate action to revoke this permit as specified by 15 NCAC 2H .0205
(c)(4)-
7. The issuance of this permit does not preclude the Permittee from complying with any and
all statutes, rules, .regulations, or ordinances which may be imposed by other government
