W. GROUNDWATER REQUIREMENTS
L The COMPLIANCE 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 40 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. Verification of the water table elevation by soil borings
must be conducted on all sites to receive residuals, within 24 hours, prior to application of
residuals. After verification of the water table is concluded, the soil borings must be filled in with
soil, to decrease the chance of residuals contaminating the surficial aquifer.
V. INSPECTIONS
The Permittee 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
Permittee. 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 or other permitting
authority, upon request.
2. 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 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.
