This legislation aims to enhance safety and oversight for foreign manufacturers of cylinders (FMOCs) used in transporting hazardous materials within the United States. It directs the Secretary of Transportation to promulgate new regulations governing the approval process for these manufacturers. Approvals will generally be for a maximum of one year, though a five-year approval may be granted to FMOCs that attest to not being prohibited from U.S. entry, certify accurate information, and demonstrate three years of compliance with relevant regulations, thus being considered "in good standing." The bill introduces several new requirements for FMOC applications, mandating that applicants answer specific questions about their compliance history, including past monetary penalties, payment delinquencies, and listings on various government watchlists. The Secretary may deny applications based on the responses to these questions. Furthermore, the legislation requires public notification and a 30-day comment period for all FMOC approval applications, increasing transparency in the process. To bolster enforcement, the Act allows for the suspension or termination of an FMOC's approval if they obstruct inspections or knowingly misrepresent information provided to the Secretary. It also mandates the creation of a process for interested parties to request a reevaluation of FMOC approvals based on evidence of inaccuracies, changes, or fraudulent attestations. Finally, the bill strengthens foreign inspection protocols by requiring annual inspections for good cause, clarifying that refusal leads to a loss of "in good standing" status, and allowing for the recovery of all associated inspection costs.
