The Designated Federal Officer (DFO) shall submit to the committee for its consideration any notice of proposed hazardous liquid pipeline safety standards published in the Federal Register, including both new standards and amendments to existing standards, to include any supporting analyses (e.g., risk assessment or economic analysis, environmental analysis). Within 90 days after receipt by the committee of any such proposal, the committee shall prepare a report on the technical feasibility, reasonableness, cost-effectiveness, and practicability of the proposal, as well as an evaluation of the merit of the data and methods used, and any recommended options relating to the risk assessment information and the associated standard that the committee determines to be appropriate.

b. Each timely report by the committee, including any minority views, shall form a part of the proceedings for the promulgation of the standard and be incorporated in the preamble published with the final rule in the Federal Register. The administrator of the Pipeline and Hazardous Materials Safety Administration (PHMSA) may prescribe a final standard at any time after the 90-day mark following a proposal’s submission to the committee, regardless of whether the committee has reported on such proposal. The administrator shall not be bound by the conclusions of the committee. In the event the conclusions of the majority of the current members of the committee are rejected, the reasons for rejection shall also be incorporated in the preamble of the final rule, 49 U.S.C. § 60115.

c. If the proposed safety standard is submitted as a Direct Final Rule and is approved by the committee, minority views will not be treated as adverse comments unless they are submitted to the docket.
