nor cause the migration of the contamination into unaffected areas. If the treatment system fails to
consistently achieve this standard, additional treatment units or changes in operational needs may be
required.

be rescinded unless the facilities are installed, maintained, and operated in a manner, which will protect
the assigned water quality standards of the surface and groundwaters.
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. Any 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.
