Ariz. Admin. Code § 18-11-121

Current through Register Vol. 30, No. 50, December 13, 2024

Section R18-11-121 - Schedules of Compliance

A compliance schedule in an AZPDES permit shall require the permittee to comply with a discharge limitation based upon a new or revised water quality standard as soon as possible to achieve compliance. The permittee shall demonstrate that all requirements under § 301(b) and § 306 of the Clean Water Act [ 33 U.S.C. 1311(b) and 1316 ] are achieved and that the point source cannot comply with a discharge limitation based upon the new or revised water quality standard through the application of existing water pollution control technology, operational changes, or source reduction. In establishing a compliance schedule, the Director shall consider:

1. How much time the permittee has already had to meet any effluent limitations under a prior permit;

2. The extent to which the permittee has made good faith efforts to comply with the effluent limitations and other requirements in a prior permit;

3. Whether treatment facilities, operations, or measures must be modified to meet the effluent limitations;

4. How long any necessary modifications would take to implement; and

5. Whether the permittee would be expected to use the same treatment facilities, operations or other measures to meet the effluent limitations as it would have used to meet the effluent limitations in a prior permit.
