nuisance conditions, the Perrriittee shall take immediate corrective actions, including those
actions that may be required by this Division, such as the construction of additional or
replacement wastewater treatment or disposal facilities.
5. This permit shall become voidable if the soils fail to adequately assimilate the wastes and
may be rescinded unless the facilities are installed, maintained, and operated in a manner
which will protect the assigned water quality standards of the surface waters and ground
waters. The ponding of wastewater on the surface of the distribution field when the dosing
cycle commences shall be considered as evidence of failure of the soils to adequately
assimilate the wastewater. Additionally, such failure shall be interpreted as a violation of
this permit condition.
6. 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.
7. 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 North Carolina Division of
Environmental Management.
8. The following buffers shall be maintained*:
