Update on Air Quality and Greenhouse Gas Regulations Affecting Landfills

The panel presentation will try to make sense out of the ever changing landscape of air quality and greenhouse gas (GHG) regulations affecting landfills. We will update the audience on the pending federal rules including their current legal status. We will provide guidance to owners and operators how they can best comply with these rules.

New Source Performance Standards Treatment Exemption: History and Evolution of this Important Concept for Landfills and Landfill Gas-to-Energy Projects

The New Source Performance Standards (NSPS) rule for municipal solid waste landfills allows for landfill gas to be routed to a treatment system and, once the gas is treated, it has effectively completed its NSPS requirements. Industry is finding that the definition of what treatment is and what is required is evolving. The 2016 NSPS Emission Guideline rules further clarified a direction for treatment that is significantly different from current interpretations. This presentation will attempt to clarify this issue, and see where it might be going in the future for facility planning.
