The requirements of this section apply to dischargers who own or operate a Class II or Class III waste management unit (Unit). This section does not apply to discharges of mining waste to mining waste management units (mining Units). [Note: The requirements of this paragraph do not preclude the RWQCB (under authority other than this subdivision) from requiring financial assurance for a known or reasonably foreseeable release at a mining Unit.] At Units for which the CIWMB does not require financial assurances for corrective action, the RWQCB shall require the discharger to establish an irrevocable fund (or to provide other means) pursuant to the CIWMB-promulgated sections of this chapter but with the RWQCB named as beneficiary, to ensure funds are available to address a known or reasonably foreseeable release from the Unit, pursuant to § 20380(b). For addressing a known or reasonably foreseeable release at a solid waste landfill, the RWQCB shall coordinate with the CIWMB, pursuant to § 20380(b) and in a manner consistent with § 20950(f).
