I. Background

On September 6, 2013, PHMSA published a notice of proposed rulemaking (ANPRM; 78 FR 54849) seeking public comments on whether issues raised in eight petitions and four NTSB recommendations would enhance safety, revise, and clarify the Hazardous Materials Regulations (HMR; 49 CFR parts 171-180) with regard to rail transport. Specifically, we requested comments on important amendments that would: (1) Enhance the standards Start Printed Page 66327for DOT Specification 111 tank cars used to transport Packing Group I and II hazardous materials; (2) explore the feasibility of additional operational requirements to enhance the safe transportation of Packing Group I and II hazardous materials; (3) afford DOT greater discretion to authorize the movement of non-conforming tank cars; (4) correct regulations that allow an unsafe condition associated with pressure relief valves (PRV) on rail cars transporting carbon dioxide, refrigerated liquid; (5) revise outdated regulations applicable to the repair and maintenance of DOT Specification 110, DOT Specification 106, and ICC 27 tank car tanks (ton tanks); and (6) except rupture discs from removal if the inspection itself would damage, change, or alter the intended operation of the device.

II. Comment Period Extension

We received a request to extend the comment period by 90-days from the Sierra Club on behalf of Climate Parents, Columbia Riverkeeper, ForestEthics, Friends of Earth, Natural Resources Defense Council, Oil Change International, San Francisco Baykeeper, Spokane Riverkeeper, Washington Environmental Council, and the Waterkeeper Alliance. The request indicates that the primary basis for extension is to allow the public a meaningful review of these proposed changes in rail safety, especially regarding tank cars transporting crude oil and tar sands while highlighting several recent tank car incidents. The request also indicates that the recent government shutdown prevented communication with DOT staff for review of the technical proposals during the initial 60-day comment period.

Although PHMSA normally considers an initial 60-day comment period sufficient time to review and respond to rulemaking proposals, due to PHMSA's desire to collect meaningful input from a number of potentially affected stakeholders, PHMSA is consenting to the commenter request to extend the comment period to ensure sufficient time for public review. However, we do not consider a 90-day extension to be warranted. Accordingly, in the interest of moving this rulemaking action forward in a timely manner, we believe, extending the comment period by 30 days would allow sufficient to time to conduct a thorough review.
