I. PERFORMANCE STANDARDS
1. 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, 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.
3. 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.
5. The following buffers shall be maintained:
a) 400 feet between wetted area and any residence. or places of public assembly under separate

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.
