U.S. Federal Register — the daily journal of the federal government (Office of the Federal Register / NARA). Search and retrieve every Rule, Proposed Rule (NPRM), Notice, and Presidential Document published since 1994, from every federal agency relevant to energy, oil & gas, and the environment (EPA, BLM, BOEM, FERC, PHMSA, NOAA, DOE, and more) — filter by agency, document type, keyword, and publication date. The regulatory "what just changed" feed: abstracts, actions, CFR references, docket IDs, comment windows, citations, and PDF/body URLs. Pairs with eCFR (current text) and Regulations.gov (dockets + comments). No auth.
