EHS Management Software and What It Cannot Compute
EHS software is a system of record. It handles the documents and dates well, and stores whatever emissions number you give it rather than deriving one.

EPA OOOO and Federal Methane Rules
The federal methane rules for oil and gas come as a series of subparts under the Clean Air Act: OOOO and OOOOa for older sites, OOOOb for sites built or modified after December 6, 2022, and OOOOc for existing sources through state plans. Which one applies depends on when a site was built or changed, and the newer rules have been amended repeatedly.
These posts explain what each subpart requires, where the compliance deadlines stand, how leak detection and repair work in practice, and what happened to the waste emissions charge. For the full picture of OOOOb, start with the explainer.
Because the rules have moved through proposals, interim final rules and amendments, the posts separate what is in effect from what is proposed and date each change. Compliance software and the records a compliance program needs to keep are covered too.
