§ 2550.10. Corrective Action Program.
(a) A discharger required pursuant to section 2550.1 of this article to establish a corrective action program for a waste management unit shall, at a minimum, comply with the requirements of this section for that unit.
(b) The discharger shall take corrective action to remediate releases from the waste management unit and to ensure that the waste management unit achieves compliance with the water quality protection standard under section 2550.2 of this article. The regional board shall specify the water quality protection standard for corrective action in the waste discharge requirements.
(c) The discharger shall implement corrective action measures that ensure that constituents of concern achieve their respective concentration limits at all monitoring points and throughout the zone affected by the release, including any portions thereof that extend beyond the facility boundary, by removing the waste constituents or treating them in place. The discharger shall take other action approved by the regional board to prevent noncompliance with those limits due to a continued or subsequent release from the waste management unit, including but not limited to, source control. The waste discharge requirements shall specify the specific measures that will be taken.
(d) In conjunction with the corrective action measures, the discharger shall establish and implement a water quality monitoring program to demonstrate the effectiveness of the corrective action program. Such a monitoring program may be based on the requirements for an evaluation monitoring program under section 2550.9 of this article, and shall be effective in determining compliance with the water quality protection standard under section 2550.2 of this article and in determining the success of the corrective action measures pursuant to subsection (c) of this section.
(e) Corrective action measures taken pursuant to this section shall be initiated and completed by the discharger within a period of time specified by the regional board in the waste discharge requirements.
(f) Corrective action measures taken pursuant to subsection (c) of this section may be terminated when the discharger demonstrates to the satisfaction of the regional board that the concentrations of all constituents of concern are reduced to levels below their respective concentration limits.
(g) After suspending the corrective action measures, pursuant to subsection (f) of this section, the waste management unit shall remain in the Corrective Action Program until an approved Detection Monitoring Program meeting the requirements of section 2550.8 of this article has been incorporated into waste discharge requirements and until the discharger demonstrates to the satisfaction of the regional board that the waste management unit is in compliance with the water quality protection standard. This demonstration shall be based on the following criteria and requirements:
(1) The concentration of each constituent of concern in each sample from each monitoring point in the Corrective Action Program for the waste management unit must have remained at or below its respective concentration limit during a proof period of at least one year, beginning immediately after the suspension of corrective action measures; and
(2) The individual sampling events for each monitoring point must have been evenly distributed throughout the proof period and have consisted of no less than eight sampling events per year per monitoring point.
(h) The discharger shall report, in writing, to the regional board on the effectiveness of the corrective action program. The discharger shall submit these reports at least semi-annually. More frequent reporting shall be required by the regional board as necessary to ensure the protection of human health or the environment.
(i) If the discharger determines that the corrective action program does not satisfy the provisions of this section, the discharger shall, within 90 days of making the determination, submit an amended report of waste discharge to make appropriate changes to the program.
(j) Any time the regional board determines that the corrective action program does not satisfy the requirements of this section, the discharger shall, within 90 days of receiving written notification of such determination by the regional board, submit an amended report of waste discharge to make appropriate changes to the program.
