Current through Register 2024 Notice Reg. No. 28, July 12, 2024
(a)
						General Requirements
(1) Alternative materials
						of alternative thickness for daily cover (other than at least six inches of
						earthen material) for municipal solid waste landfill units may be approved by
						the EA with concurrence by the Department, if the owner or operator
						demonstrates that the alternative material and thickness control vectors,
						fires, odors, blowing litter, and scavenging without presenting a threat to
						human health and the environment.
(2) Alternative daily cover alone, or in
						combination with compacted earthen material, shall be placed over the entire
						working face at the end of each operating day or at more frequent intervals to
						control vectors, fires, odors, blowing litter, and scavenging without
						presenting a threat to human health and the environment. 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. Waste-derived alternative daily cover shall
						be processed prior to spreading and compacting on the working face and applied
						and compacted to ensure that all exposed waste is completely covered by ADC and
						that there are no open voids within the cover material or in contact with the
						underlying wastes. Waste materials used as ADC that already meet the grain-size
						specifications of these regulations, or an alternative grain size approved by
						the EA and Department pursuant to this section, need not be processed if the EA
						determines that the material as received at the landfill is adequate to perform
						the functions of daily cover and meets the appropriate
						specifications.
(3) Should the
						application of alternative daily cover become impracticable or contribute to
						conditions hazardous to public health and safety and the environment, the owner
						or operator shall terminate such use and revert to the use of compacted earthen
						cover material in accordance with section
						20680. For the purposes of this
						section, impracticable conditions are those which make placement of alternative
						daily cover difficult due to adverse climatic or other conditions such that the
						performance requirements of (a)(2) cannot be met.
(4) The owner or operator shall place
						compacted earthen material over the entire working face at the end of any
						operating day preceding a period of time greater than 24 hours when the
						facility is closed, unless procedures as required by the EA are in place to
						ensure that the requirements of (a)(2) and (a)(3) are met. A stockpile of
						earthen cover material and required equipment shall be available to ensure a
						corrective response to violation of (a)(2) and (a)(3). Whenever an EA
						determines that an application of ADC is not meeting the requirements of this
						standard, the EA may direct the operator to immediately cover the ADC with
						soil. The continuing use of ADC that has been determined by the EA as not
						meeting the requirements of this section may become the basis for the EA to
						take enforcement action to seek compliance with the requirements of this
						section.
(5) The owner or operator
						shall maintain a record of waste derived alternative daily cover in accordance
						with Title 14, California Code of Regulations, Division 7, Chapter 9, Article
						9.25, Section
						18815.1 et seq. The records shall
						be available for inspection by authorized representatives of the EA, the local
						health agency, and the Department during normal business hours and retained in
						the operating record near the site or in an alternative location approved by
						the EA.
(6) For waste
						classification, composition, and liquid percolation requirements of alternative
						daily cover, refer to the SWRCB requirements set forth in section
						20705.
(7) Waste derived materials used as
						alternative daily cover shall be restricted to quantities no more than
						necessary to meet the performance requirements of (a)(2), or as specified in
						subdivision (b) of this section. Should the Department determine after
						consulting with the EA that an owner or operator violated this standard, the
						owner or operator shall revise the applicable reports to reflect the overuse as
						disposal, and pay the required California Department of Tax and Fee
						Administration (CDTFA) disposal tipping fees for the amount of overuse. EAs
						shall not be responsible for making such determinations.
(8) Compost, co-compost, and chemically fixed
						sewage sludge and water treatment sludge only, that meet the performance
						standards for cover material, shall be limited to up to 25 percent of landfill
						cover materials or landfill cover extenders as required under Public Resources
						Code (PRC) section
						42245. For the purposes of this
						section, "chemically fixed sewage sludge" means solid and semisolid residue
						generated during the treatment of domestic sewage. The 25 percent limit shall
						apply on a quarterly basis to the total daily and intermediate cover or cover
						extender use. For the purposes of this section, landfill cover extenders shall
						mean compost, co-compost, or chemically fixed sewage sludge blended or mixed
						with soil.
(9) Storage and handling
						of waste derived materials at the landfill for use as alternative daily cover
						shall be conducted in a manner to protect public health and safety and the
						environment, and to control vectors, fires, odors, blowing litter, scavenging,
						and nuisances.
(10) The EA shall
						apply this section to disposal facilities other than municipal solid waste
						landfill units as necessary to control vectors, fires, odors, blowing litter,
						scavenging, and nuisances without presenting a threat to human health and the
						environment. This requirement shall also apply to municipal solid waste
						landfills which qualify for a delay in the general compliance date or
						additional flexibility as specified in 40 CFR Part 258.
(11) The owner or operator shall implement a
						program described in the Report of Disposal Site Information as required by
						section 21600(b)(6) to
						minimize contamination of alternative daily cover with wastes not included
						within the individual alternative daily cover material types specified in
						subdivision (b) of this section and wastes that would conflict with the
						performance requirements of (a)(2).
