NC Division of Water Quality
Water Quality Section
Non -Discharge Compliance/Enforcement Unit
1617 Mail Service Center
Raleigh, North Carolina 27699-1617
So Noncompliance Notification:
The Permittee shall report by telephone to the Winston-Salem Regional Office, telephone number (336)
771-4600 or to the Raleigh Regional Office, telephone number [phone], as soon as possible, but
in no case more than 24 hours or on the next working day following the occurrence or first knowledge
of the occurrence of any of the following:
a. Any occurrence with the Iand application program which results in the land 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 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 residual treatment.
e. Any spillage or discharge from a vehicle or piping system transporting residuals to the application
site.
Persons reporting such occurrences by telephone shall also file a written report in letter form within
five (5) days following first knowledge of the occurrence. This report must outline the actions taken or
proposed to be taken to ensure that the problem does not recur.
IV. GROUNDWATER REQUIREMENTS
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 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.
Any groundwater quality monitoring, as deemed necessary by the Division, shall be provided.
No land application of waste activities shall be undertaken when the vertical separation between waste
and water table is less than three feet. Verification of 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 water table is concluded, the soil boring must be filled in with soil, to decrease the
chances of residuals contaminating the surficial aquifers.
4. The rate of residuals application shall be reduced 50 percent of the normal approved arate during the
months of December through March inclusive.
5. The total annual residuals budget shall be applied in not less than two separate application events each
year.
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.
VL GENERAL CONDITIONS
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
