Lessening unintended emissions known as fugitive emissions is one set of actions in this proposal to constrain large emissions sources known as super-emitters. The rulemaking requests both information and comments on alternative measurement tech

The EPA is seeking input on technologies that could distinguish large emission events and a definitional emissions level for designating an event as “large.” It is specified in the rulemaking that “any emissions visible b
