1. Any groundwater quality monitoring as deemed necessary by the Division of
Environmental Management shall be provided
2. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below land surface.

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 Iocation 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 perimeter of the waste 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 BQIINDARY- 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.
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 Pernuttee 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
trust be kept under the terms and conditions of this permit; or may obtain samples of
groundwater, surface water, or leachate.
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.
