Hazardous Materials: Frequently Asked Questions-Applicability of the Hazardous Material Regulations

Notice; request for comments.

PHMSA is announcing an initiative to convert historical letters of interpretation (LOI) applicable to the Hazardous Materials Regulations that have been issued to specific stakeholders into broadly applicable frequently asked questions on its website. By creating a repository of frequently asked questions, PHMSA seeks to eliminate the need for recurring requests for common letters of interpretations. This Federal Register Notice introduces this initiative and its objectives to those subject to the Hazardous Materials Regulations. PHMSA's objective is to gain insight regarding the utility of this initiative and topics to prioritize in the development of future frequently asked questions. PHMSA requests comment on the initiative and input on the prioritization of future sets of frequently asked questions.
