the following specified conditions and limitations:
L PERFORMANCE STANDARDS
The distribution residuals program shall be effectively maintained and operated as a non -discharge
system to prevent the discharge of any wastes resulting from the operation of this program.
2. This permit shall become voidable in the event of failure of the residuals program to adequately
protect the assigned water quality standards of the surface waters 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 program.

nuisance conditions, the Permittee shall take any immediate corrective actions as may be required
by the Division of Water Quality (Division).

distributed to the buyer. If an alternate storage site is to be used, approval must be obtained from
