Review – PHMSA Publishes Space Support Hazmat ANPRM

Today DOT’s Pipeline and Hazardous Materials Safety Administration (PHMSA) published an advanced notice of proposed rulemaking (ANPRM) in the Federal Register (91 FR 3860-3862) on “Hazardous Materials: Modernizing Regulations To Facilitate Transportation of Hazardous Materials Integral to Spacecraft Components and Payloads”. PHMSA is soliciting feedback on streamlining and modernizing the Agency's regulations as they relate to the transportation of hazardous materials integral to spacecraft payloads or components. This rulemaking supports the intent of EO 14335, Enabling Competition in the Commercial Space Industry, even though there are no specific mentions of PHMSA or Hazmat regulations in that EO.

Public Comments

PHMSA is soliciting public comments. Comments may be submitted via the Federal eRulemaking Portal (www.Regulations.gov; Docket #PHMSA-2024-0065). Comments should be submitted by April 29th, 2026.
