(a) Applicability and frequency of cover.

1. (1) The owners or operators of all Class 4 landfills must cover disposed solid waste with six inches (6”) of earthen material at least weekly or at more frequent intervals if necessary, to control disease vectors, fires, odors, blowing litter, scavenging, and to limit the generation of leachate.
2. (2) Daily spreading and compaction of the waste shall be performed to minimize void space and reduce the potential for disease vectors and fires.

(c) Temporary waiver.

1. (1) The Director of the Division of Environmental Quality may grant a temporary waiver from the requirements of subsections (a) and (b) 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 section.
