depth to water in each well shall be measured from the surveyed point on the top of the casing.
3. The measuring points (top of well casing) of all monitoring wells shall be surveyed to provide the
relative elevation of the measuring point for each monitoring well.
4. If any volatile organic compounds are detected by Method 6230D, then the Wilmington Regional
Office Aquifer Protection Supervisor, telephone number [phone], must be contacted
immediately for further instructions regarding any additional follow-up analyses required. The results
of all initial and follow-up analyses must be submitted simultaneously.
5. The results of the sampling and analysis must be received on Form GW-59 (Groundwater Quality
Monitoring: Compliance Report Form) by the Division of Water Quality, Information Processing
Unit, 1617 Mail Service Center, Raleigh, North Carolina 27699-1617 on or before the last working
day of the month following the sampling month.

6. The COMPLIANCE BOUNDARY for the disposal system is specified by regulations in 15A NCAC

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).
7. In accordance with 15A NCAC 2L, a REVIEW BOUNDARY is established around the disposal

proctor standard dry density and installed and compacted in layers no thicker than six inches, with a
hydraulic conductivity of no greater than 1 x 10-6 cm/sec.
9. Waste application activities shall not occur when vertical separation between depth of application and
the water table is less than one foot. Verification of the water table elevation can be confirmed by
water level readings obtained from the monitoring well(s) near the site or auger boring(s), which must
be done within 24 hours prior to the application of wastewater. Any open borings must be properly
filled with native soil prior to the application of wastewater, to decrease the chance of any waste
contaminating the groundwater.
V. INSPECTIONS
I. Adequate inspection, maintenance, and cleaning shall 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 Pcrmittee 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 Pennittee for a period of three years from the date of the inspection and shall be
made available upon request to the Division or other permitting authority.
3. Any duly authorized officer, employee, or representative of the Division may, upon presentation of
credentials, enter and inspect any property, premises or place on or related to the disposal 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 maintained under the terms and conditions of this permit,
and may obtain samples of groundwater, surface water, or leachate.
VI. GENERAL CONDITIONS
1. This permit shall become voidable unless the facilities are constructed in accordance with the
conditions of this permit, the approved plans and specifications, and other supporting data.
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
there is a name change of the Permittee, a formal permit request must be submitted to the Division
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.
7

4. Failure to abide by the conditions and limitations contained in this permit may subject the Permittee
to an enforcement action by the Division in accordance with North Carolina General Statute 143-
215.6A to 143-215.6C.
The issuance of this permit does not exempt 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, including but not limited to applicable river buffer rules in 15A
NCAC 2B .0200, erosion and sedimentation control requirements in 15A NCAC Chapter 4 and under
the Division's General Permit NCG010000, and any requirements pertaining to wetlands under 15A
NCAC 2B .0200 and 211.0500.
