§ 20705. SWRCB--Standards for Daily and Intermediate (Interim) Cover. (C15: § 2544)
[Note: This section applies in conjunction with CIWMB sections 20680-20701 and addresses cover issues prior to the installation of the final cover. Readers interested in the SWRCB-promulgated requirements for final cover will find them at § 21090.]
(a) Daily & Intermediate--Interim cover at landfills is “daily cover” and “intermediate cover” as defined by the CIWMB (see § 20160).
(b) Minimize Percolation--Interim cover over wastes discharged to a landfill shall be designed and constructed to minimize percolation of liquids through wastes.
(c) For Class II Waste Piles--Cover may be required by RWQCBs for Class II wastes piles.
(d) [Reserved]
(e) Limitations On Cover Materials--Except for reusable covers that are never incorporated into the Unit, daily and intermediate cover shall only consist of materials:
(1) Match Unit Classification--which meet the classification criteria for wastes that can be discharged to that landfill. Therefore, a material that would be classified as a designated waste cannot be utilized for daily or intermediate cover at a Class III landfill unless that material is approved for discharge (as a waste) to that landfill pursuant to § 20200(a)(1); and
(2) Composition--whose constituents (other than water) and foreseeable breakdown byproducts, under the chemical (including biochemical) and temperature conditions which it is likely to encounter within the landfill, either:
(A) for non-composite lined portions of the Unit, are mobilizable only at concentrations which would not adversely affect beneficial uses of waters of the state, in the event of a release; or
(B) for composite-lined portions of the Unit, are listed as COCs in the Unit's water quality protection standard (Water Standard), created pursuant to § 20395.
(f) Dust Control--The requirements of § 21090(a)(5) regarding the discharge of leachate, gas condensate, and other liquids to final-covered portions of the Unit also apply to the discharge of liquids to daily and intermediate cover, including discharges made for the purpose of dust control.
