Hazardous Materials: Revision of Requirements for Carriage by Aircraft

Notice of proposed rulemaking (NPRM).
RSPA is proposing changes to the requirements in the Hazardous Materials Regulations (HMR) for the transportation of hazardous materials by aircraft. These proposed changes include clarifying the applicability of part 175; excepting cargo aircraft from the quantity limits in Sec. 175.75; reformatting the exceptions in Sec. 175.10 into three sections based on applicability; and providing new separation distances for the shipment of radioactive materials by cargo aircraft. These changes are being proposed in order to clarify requirements to promote safer transportation practices; promote compliance and enforcement; eliminate unnecessary regulatory requirements; convert certain exemptions into regulations of general applicability; finalize outstanding petitions for rulemaking; facilitate international commerce; and make these requirements easier to understand.
