Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						General--A discharger required pursuant to §
												20385 to establish a corrective
						action program for a Unit shall, at a minimum, comply with the requirements of
						this section for that Unit.
(b)
						Standards--The discharger shall take corrective action to achieve the following
						goals: to remediate releases from the Unit; to ensure that the discharger
						achieves compliance with the Water Standard adopted under §
												20390 for that Unit. The RWQCB
						shall specify the Water Standard for corrective action [including any
						concentration limits greater than background, under §
												20400 (c-g)] in the
						WDRs.
(c) Scope of Actions--The
						discharger shall implement corrective action measures that ensure that COCs
						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
						RWQCB to prevent noncompliance with those limits due to a continued or
						subsequent release from the Unit, including but not limited to, source control.
						The WDRs shall specify the specific measures that will be taken.
(d) Monitoring--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 can be based on the
						requirements for an evaluation monitoring program (under §
												20425), and shall be effective in
						determining compliance with the Water Standard (under §
												20390) and in determining the
						success of the corrective action measures pursuant to ¶(c).
(e) Compliance Schedule--Corrective action
						measures taken pursuant to this section shall be initiated and completed by the
						discharger within a period of time specified by the RWQCB in the
						WDRs.
(f) Terminating
						Measures--Corrective action measures taken pursuant to
						¶(c)(
e
.
g., pumping and treatment of ground
						water
) may be terminated when the discharger demonstrates to the
						satisfaction of the RWQCB that the concentrations of all COCs are reduced to
						levels below their respective concentration limits throughout the entire zone
						affected by the release.
(g)
						Demonstrating Completion of CAP--After suspending the corrective action
						measures, pursuant to ¶(f), the Unit shall implement the remaining
						portions of the Corrective Action Program until an approved Detection
						Monitoring Program meeting the requirements of §
												20420 has been incorporated into
						WDRs and until the discharger demonstrates to the satisfaction of the RWQCB
						that the Unit is in compliance with the Water Standard (under §
												20390). If the Unit is an MSW
						landfill, then this demonstration shall meet the federal requirements
						incorporated by reference in SWRCB Resolution No. 93-62 [see §
												258.58(c) of
						40CFR
						258], in lieu of meeting the requirements of
						¶(g)(1 & 2). For all other Units, this demonstration shall be based on
						the following criteria and requirements:
(1)
						the concentration of each COC in each sample from each Monitoring Point in the
						Corrective Action Program for the 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.
