WQ0003299 issued January 8, 1999, and shall be subject to the following specified conditions and limitations:
L PERFORMANCE STANDARDS
The surface irrigation facilities shall be effectively maintained and operated at all times so that there
is no discharge to the surface waters, nor any contamination of ground waters which will render them
unsatisfactory for normal use. In the event that the facilities fail to perform satisfactorily, including
the creation of nuisance conditions or failure of the irrigation area to adequately assimilate the
wastewater, the Permittee shall take immediate corrective actions including those actions that may be
required by the Division of Water Quality (Division), such as the construction of additional or
replacement wastewater treatment and disposal facilities.
2. The issuance of this permit shall not relieve the Permittee of the responsibility for damages to surface
or groundwaters resulting from the operation of this facility.
The residuals generated from these treatment facilities must be disposed in accordance with General
Statute 143-215.1 and in a manner approved by the Division.
4. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited_

The following buffers shall be maintained:
a) 400 feet between wetted area and any residence or places of public assembly under separate
ownership,
b) 150 feet between wetted area and property lines,
c) 100 feet between wetted area and wells,
d) 100 feet between wetted area and drainage ways or surface water bodies,
e) 50 feet between wetted area and public right of ways,
f) 100 feet between treatment/storage units and any wells, and
g) 50 feet between treatment units and property lines.
Some of the buffers specified above may not have been included in previous permits for this waste
treatment and disposal system. These buffers are not intended to prohibit or prevent modifications,
which are required by the Division, to improve performance of the existing treatment facility. These
buffers do, however, apply to modifications of the treatment and disposal facilities that are for the
purpose of increasing the flow that is tributary to the facility. These buffers do apply to any
expansion or modification of the irrigation areas and apply in instances in which the sale of property
would cause any of the buffers now complied with, for the treatment and disposal facilities, to be
violated. The applicant is advised that any modifications to the existing facilities will require a permit
modification.

the Review Boundary shall require action in accordance with 15A NCAC 2L .0106(d)(1).
5. Waste application shall not occur when the vertical separation between depth of application and the
water table is at less than three (3) feet. Verification of the water table elevation can be. confirmed by
water level readings obtained from the monitor wells near the site or auger borings, which must be
done within 24 hours, prior to application to decrease the chance of any waste contaminating the
groundwater.
6. Within sixty (60) days of permit issuance, the soil in the application areas shall be modified by the
following procedure: During a time when the soil is not wet, a small piece of equipment is to be used
to disc and plow those areas which are known to have "standing water" problems. The intent off this
procedure is to break up the compacted soil. These areas shall then be filled with a loose grained top
soil and leveled. The areas will then be replanted with fescue.
Within sixty (60) days of permit issuance, the function of all spray heads shall be examined. Those
spray heads which are not functioning properly shall be immediately replaced.

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 Permittee 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 to the Division or other permitting authority.
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.
