- Operators and owners.
- Consultants.
The EA states:
- MSW landfills are the third largest source of methane emissions in the United States.
- More than 100 inspections over the past three years indicate that many operators are not complying with the Clean Air Act’s applicable regulatory requirements.
The EA identifies as compliance issues:
- Improper monitoring resulting in excess surface emissions of methane.
