I. Background

On March 11, 2011, PHMSA published an NPRM (HM-247; 76 FR 13313) seeking public comment on a proposal to amend the HMR requirements for cargo tank loading or unloading operations. Specifically, the NPRM amendments included requirements to:

  • Assess the risks of loading and unloading operations and develop written operating procedures based on the risk assessment;
  • Train hazmat employees in the relevant aspects of the operational procedures;
  • Qualify annually hazmat employees who perform loading and unloading operations;
  • Develop and implement a periodic maintenance schedule for equipment and conduct periodic operational tests of equipment; and
  • Ensure that the equipment meets the performance standards.

In the NPRM, we invited comment on a number of provisions as well as comment on the methodology used to develop the regulatory evaluation supporting the NPRM. See the March 11, 2011 NPRM for a complete discussion of the proposals and requests for comment and information.

II. Comment Period Extension

Given the abundance of requests for comment and data contained in this NPRM as well as our consideration of a number of other proposed rulemakings concurrently impacting interested parties affected by the cargo tank motor vehicle proposals in this notice, we are providing affected entities as well as the general public an additional 30 days to allow for thorough review, analysis, and response to the NPRM. Thus, the comment period for the HM-247 NPRM is extended from May 10, 2011 until June 9, 2011.
