Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						Except as provided in ¶(b), (f) and §
												20690, the owners or operators of
						all municipal solid waste landfill units shall cover disposed solid waste with
						a minimum of six inches of compacted earthen material at the end of each
						operating day, or at more frequent intervals if necessary, to control vectors,
						fires, odors, blowing litter, and scavenging. For the purposes of this section,
						the operating day shall be defined as the hours of operation specified in the
						solid waste facility permit, and may extend for more than 24 hours if
						operations are continuous.
(b) The
						EA, with concurrence by the CIWMB, may grant a temporary waiver from the
						requirements of ¶(a) if the owner or operator demonstrates that there are
						extreme seasonal climatic conditions that make meeting such requirements
						impractical.
(c) Earthen material
						or alternative cover materials of alternative thickness shall be placed over
						all surfaces of disposed solid waste for other than municipal solid waste
						landfill units, as required by the EA to control vectors, fires, odors, blowing
						litter, and scavenging without presenting a threat to human health and the
						environment.
(d) For the purposes
						of this section, earthen material shall include contaminated soil as defined in
						Title 14, California Code of Regulations, §
												17361(b), and
						soil with contaminants other than petroleum hydrocarbons which has been
						approved for use as landfill daily cover by the RWQCB, and any other
						governmental agencies from which approval is required, such as the Department
						of Toxic Substances Control and Air Pollution Control District or Air Quality
						Management District.
(e) For waste
						classification, composition, and liquid percolation requirements of daily
						cover, refer to the SWRCB requirements set forth in §
												20705 of this article.
(f) For those MSWLFs that accept for disposal
						20 tons or less of municipal solid waste per day based on an annual average,
						the EA, with concurrence by the Board, may establish alternative frequencies
						for daily cover after consideration of the unique characteristics of small
						communities, climatic and hydrogeologic conditions, and protection of human
						health and the environment. Any proposal to allow an alternative frequency
						shall be available for public review for a minimum of 30 days to allow affected
						parties the opportunity to comment. Documentation of the considerations, public
						comment and Board concurrence for any alternative frequency shall be placed in
						the operating record. The Executive Director or the EA may condition, limit,
						suspend, or terminate an operator's use of an alternative monitoring frequency
						if it is determined that the alternative frequency would cause harm to public
						health and safety, or the environment.
