In the event that the facilities fail to perform satisfactorily, including the creation of nuisance conditions, 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. 3. 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. 4. This permit shall become voidable if the soils fail to adequately assimilate the wastes and may be rescinded unless the facilities are installed, maintained, and operated in a manner which will protect the assigned water quality standards of the surface waters and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. 5. Adequate measures shall be taken to divert stormwater from the disposal area and prevent wastewater runoff from the disposal area. 6. 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. 7. Diversion or bypassing of the untreated wastewater from the treatment facilities is prohibited. 8.
