Trump grants two-year HON Rule deadline relief for listed chemical plants
President Donald Trump on July 13, 2026, issued a proclamation extending by two years certain compliance deadlines under the EPA’s Hazardous Organic NESHAP, known as the HON Rule, for stationary sources listed in an annex to the order. The action relies on Clean Air Act section 112(i)(4) and applies only to the named sources and the specific deadlines identified in the proclamation.
The White House said the covered facilities are tied to chemical manufacturing and related supply chains that support semiconductors, medical device sterilization, advanced manufacturing, and defense needs. The proclamation does not repeal the HON Rule or rewrite the air toxics standards themselves. It postpones compliance timing for selected facilities that were facing deadlines under the rule.
That distinction matters. The order is narrow, not industry-wide. It does not grant a blanket exemption to every chemical plant, and it does not erase all obligations under the HON Rule. Instead, it delays only the deadlines the administration chose to cover for the listed stationary sources.
The move is likely to draw a split reaction. Backers will cast it as a way to avoid disrupting strategically important manufacturing. Critics will see it as another delay in pollution controls meant to limit hazardous air emissions near nearby communities. Either way, the legal effect is limited to the facilities named in the annex and the compliance dates spelled out in the proclamation.
