1. The MM-PLIANCE BOUNDARY for the disposal system is specified by regulations in
15A NCAC 2L, Groundwater Classifications and Standards. The Compliance Boundary is
for the disposal system constructed after December 31, 1983 is established at either (1) 250
feet from the waste disposal area, or (2) 50 feet within the property boundary, whichever is
closest to the waste disposal area. An exceedance of Groundwater Quality Standards at or
beyond the Compliance Boundary is subject to immediate remediation action in addition to
the penalty provisions applicable under General Statute 143-215.6A(a)(1).
In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the
disposal systems midway between the Compliance Boundary and the perimeter of the
waste disposal area. Any exceedance of standards at the Review Boundary shall require
remediation action on the part of the permittee.
2. Any groundwater quality monitoring, as deemed necessary by the Division, shall be
provided.
3. No land application of waste activities shall be undertaken when the seasonal high water
table is less than three feet below land surface.
The Pennittee or his designee shall inspect the residuals storage, transport, and application
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 maintain 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 Pere- ttee. This log of inspections shall be maintained by the Permittee
for a period of five years from the date of the inspection and shall be made available to the
Division of Environmental Management or other permitting authority, upon request.
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 application site or 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; and may obtain samples of
groundwater, surface water, or leachate.
Ila
1. This permit shall become voidable unless the land application activities are carried out in
accordance with the conditions of this permit, the supporting materials, 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 automatically transferable. In the event that 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.

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
agencies (local, state, and federal) which have jurisdiction.
8. The Permittee, at least six (6) months prior to the expiration of this permit, shall request its
extension. Upon receipt of the request, the Commission will review the adequacy of the
facilities described therein, and if warranted, will extend the permit for such period of time
and under such conditions and limitations as it may deem appropriate.
9. This permit may be modified, or revoked and reissued to incorporate any conditions,
limitations and monitoring requirements the Division of Environmental Management deems
necessary in order to adequately protect the environment and public health.
10. This permit shall become voidable unless the agreements between the Permittee and the
landowners/lessees are in full force and effect. The land owner agreements are considered
expired concurrent with the expiration date of the permit and must be renewed at the same
time the permit is renewed.
Permit issued this the 20th day of April, 1994
