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 render the
facility incapable of adequate sludge treatment.
e. Any spillage or discharge from a vehicle or piping system transporting sludge to

IV. GROUNDWATER REQUIREMENTS
I . All buffers as contained in 15A NCAC 2H.0219 shall be maintained.
2. The Compliance Boundary for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. An exceedance of
Groundwater Quality Standards beyond the Compliance Boundary is subject to the
penalty provisions applicable under General Statute I43 -215.6(1)a. The sale of
property, by the Permittee, which is within or contiguous to thedisposal site, may
alter the 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.
7

If the title to any property which may affect the location of the Compliance
Boundary is changed, the Permittee shall notify the DEM Director within 14 days.
The Director shall then establish a modified Compliance Boundary which will be
done as a modification to the Permit. Please be advised that the movement of the
Boundary may result in a condition that would cause projected Groundwater
Standard violations and require the removal of land application sites from this
permit.
The REVIEW BOUNDARY 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.
No land application of waste activities shall be undertaken when the seasonal high
water table is less than three feet below land surface.
4. Any additional groundwater quality monitoring as deemed necessary by the
Division shall be provided.
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
