      s 20385. SWRCB - Required Programs. (C15: s2550.1)

      (a) Monitoring Programs & their Respective Triggers -A discharger subject 
      to this article shall conduct a monitoring and response program, approved 
      by the RWQCB, for each Unit at the facility as follows.

      (1) Detection Monitoring (default) -The discharger shall institute a 
      detection monitoring program (under s20420) except as required below under 
      ¶(a)(2-4);

      (2) Evaluation Monitoring (trigger #1) -The discharger shall institute an 
      evaluation monitoring program (under s20425) whenever there is "measurably 
      significant" (see s20164) evidence of a release from the Unit during a 
      detection monitoring program [under s20420(g or i)];

      (3) Evaluation Monitoring (trigger #2) -The discharger shall institute an 
      evaluation monitoring program (under s20425) whenever there is significant 
      physical evidence of a release from the Unit. Significant physical 
      evidence of a release includes unexplained volumetric changes in surface 
      impoundments, unexplained stress in biological communities, unexplained 
      changes in soil characteristics, visible signs of leachate migration, and 
      unexplained water table mounding beneath or adjacent to the Unit and any 
      other change to the environment that could reasonably be expected to be 
      the result of a release from the Unit; and

      (4) Corrective Action -The discharger shall institute a corrective action 
      program under s20430 of this article when the RWQCB determines (pursuant 
      to s20425) that the assessment of the nature and extent of the release and 
      the design of a Corrective Action Program have been satisfactorily 
      completed and the RWQCB approves the application for an amended report of 
      waste discharge for corrective action submitted by the discharger during 
      an evaluation monitoring program [pursuant to s20425(d)].

      (b) Preparation for Other Programs -The RWQCB shall specify in the WDRs 
      the specific type or types of monitoring programs required and the 
      specific elements of each monitoring and response program. For each Unit, 
      the RWQCB shall require one or more of the programs identified in ¶(a) 
      that is appropriate for the prevailing state of containment at the Unit, 
      and shall specify the circumstances under which each of the programs will 
      be required. In deciding whether to require the discharger to be prepared 
      to institute a particular program, the RWQCB shall consider the potential 
      adverse effects on human health or the environment that might occur before 
      final administrative action on an amended report of waste discharge to 
      incorporate such a program could be taken.

      (c) Concurrent Detection Monitoring Program, Where Necessary -In 
      conjunction with an evaluation monitoring program or a corrective action 
      program, the discharger shall continue to conduct a detection monitoring 
      program as necessary to provide the best assurance of the detection of 
      subsequent releases from the Unit.
