(a) WDR Scope & Purpose--The RWQCB shall adopt waste discharge requirements (WDRs) that implement the applicable provisions of this title.

(b) WDR Revision--The RWQCB shall revise WDRs as necessary to implement the provisions of this title.

(c) Reclassification--Unit classifications and WDRs for existing Units shall be fully reviewed in accordance with schedules established by the RWQCB. The WDRs shall be revised to incorporate reclassification and retrofitting requirements as provided in § 20080(e) and § 20310, and to comply with applicable monitoring and response programs required under Article 1, Subchapter 3, Chapter 3 of this division (§ 20380 et seq.). The RWQCB shall specify in WDRs the schedule for retrofitting of existing Units. All retrofitting shall be complete within five years from the issuance of the revised WDRs.

(d) Local Agencies--WDRs for new Units or for expansion of Units beyond the RWQCB- Permitted Area on July 18, 1997 shall not be effective until the RWQCB is notified that all local agencies with jurisdiction to regulate land use, solid waste disposal, air pollution, and to protect public health have approved use of the site for discharges of waste to land.

(e) Consolidation of Requirements at Multi-Unit Facilities--At the discretion of the RWQCB, WDRs for all Units in a single facility can be combined into a single set of WDRs applicable to the facility as a whole and to each respective Unit within the facility, but only if the requirements that apply to each respective Unit are clearly identified. Likewise, the RWQCB can consolidate the requirements relating to precipitation and drainage control systems for two or more adjacent Units, provided that such consolidated requirements reflect standards for the highest classification of Unit involved. Each solid waste Unit at a facility shall have its own respective monitoring program(s) under Article 1, Subchapter 3, Chapter 3 of this division (§ 20380 et seq.); nevertheless, Units can share Monitoring Points, Background Monitoring Points, sampling efforts, and reporting periods to the degree that the RWQCB concurs that such sharing does not interfere with achieving the goal of the monitoring program(s) at each respective Unit.

(f) Records--The discharger shall be required to maintain legible records of the volume and type of each waste discharged at each Unit and the manner and (for Units other than surface impoundments) location of discharge. Such records shall be on forms approved by the SWRCB or RWQCB and shall be maintained at the waste management facility until the beginning of the post-closure maintenance period. These records shall be available for review by representatives of the SWRCB and RWQCB at any time during normal business hours. At the beginning of the post-closure maintenance period, copies of these records shall be sent to the RWQCB.
