Summary

EPA posts CAA rulings on public Dashboard
The EPA has posted written applicability determinations, alternative monitoring decisions, and regulatory interpretations for Clean Air Act sections 111, 112, and 129 to a public Dashboard. The Dashboard contains determinations signed after May 2019, was put into use on October 2, 2023, and 62 documents were added to it on June 25, 2025; entries are searchable by facility name, affected subpart, response date, or free-text search.
EPA offers alternative monitoring and interpretations
Under existing regulations the EPA responds to written inquiries and can issue applicability determinations, alternative monitoring decisions, and regulatory interpretations (for example under 40 CFR 60.13(i), 61.14(g), 63.8(b)(1), 63.8(f), and 63.10(f)). Facilities can request EPA permission to use monitoring or recordkeeping that differs from the rule text and can ask whether planned actions count as construction, reconstruction, or modification.
