However, in the case of landfills referred to in the second paragraph of section 32, the biogas collection system and the biogas removal equipment must be designed to operate so that the collection and removal of any biogas produced by the landfilled residual materials may begin, even though the disposal area has not yet received a final cover, not later than 5 years after the landfilling in the case of landfills receiving 100,000 tons or less of residual materials per year or, in the case of landfills receiving more than 100,000 tons per year, not later than 1 year after the landfilling.
The operation of a biogas collection system must not result in an increase in temperature likely to cause a fire in a disposal area.
