3_ The spray 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 assirnilate 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.
4. The issuance of this permit shall not relieve the Perrnittee 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.
6. 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
ownership,
