8 CAR § 60-512 – Cover material requirements

(a) Daily cover. The owners or operators of all Class 3 landfills must cover disposed solid waste with six inches (6”) of earthen material at the end of each operating day, or at more frequent intervals if necessary, to control disease vectors, fires, odors, blowing litter, and scavenging, and to limit the generation of leachate.
(b) Intermediate cover. A compacted layer of cover soil of sufficient quantity to ensure there is not exposed waste, but not less than twelve inches (12”), including the six inches (6”) of daily cover required under subsection (a) of this section, shall be applied upon surfaces that will not receive an additional application of waste or final cover within thirty (30) days.
(c) Alternative cover materials. Alternative cover materials of an alternative thickness (other than at least six inches (6”) of earthen material) may be approved by the Director of the Division of Environmental Quality, either through individual requests or through generalized Division of Environmental Quality approval upon demonstration that the alternative material and thickness controls disease vectors, fires, odors, blowing litter, and scavenging without presenting a threat to human health and the environment.
(d) Alternative cover frequency. The director may approve alternative frequencies for the application cover materials, including the approval of a waiver of daily and intermediate cover material requirements, if the owner or operator demonstrates that less frequent or no cover will adequately meet the requirements of this section.
(e) Temporary waiver.
1. (1) The director may grant a temporary waiver from the requirements of this section if the owner or operator satisfactorily demonstrates that extreme conditions exist that make meeting such requirements impractical.
2. (2) Failure of the operator to stockpile adequate cover material shall not constitute justification for a waiver under this subsection.
