National Emission Standards for Hazardous Air Pollutants: Chemical Manufacturing Area Sources Technology Review
EPA finalizes amendments to NESHAP for chemical manufacturing area sources, requiring technology reviews and potential emission control upgrades.
Aforeworn detected this change in the Environmental & Emissions Compliance (EPA) space on July 29, 2026 and published this briefing so affected operators are forewarned rather than caught off guard. It is rated Medium urgency. Owners and operators of chemical manufacturing area sources subject to NESHAP subparts (e.g., subparts VVV, MMM, etc.) should confirm how it applies to their specific situation before acting. There is a time constraint attached: Effective 60 days after publication in the Federal Register (publication date April 1, 2026; effective date May 31, 2026). Compliance dates vary by subpart..
