[Docket No. PHMSA-2017-0102]

Hazardous Materials: Enhanced Tank Car Standards and Operational
Controls for High-Hazard Flammable Trains

AGENCY: Pipeline and Hazardous Materials Safety Administration (PHMSA),
DOT.

ACTION: Notification of availability; request for comments.

-----------------------------------------------------------------------

SUMMARY: This document provides notice that PHMSA and the Federal
Railroad Administration (FRA) are publishing a revised Regulatory
Impact Analysis (RIA) updating the original RIA associated with the
electronically controlled pneumatic (ECP) brake provision of PHMSA's
May 8, 2015, Final Rule titled ``Enhanced Tank Car Standards and
Operational Controls for High-Hazard Flammable Trains'' (Final Rule).
The agencies are publishing the updated RIA in response to the mandate
of the Fixing America's Surface Transportation (FAST) Act. The updated
RIA incorporates new testing and analysis the National Academy of
Sciences (NAS) reviewed, recommendations from two U.S. General
Accountability Office (GAO) audits, and updates to the costs and
benefits of the provision of the Final Rule based on current economic
conditions. PHMSA invites comments on all aspects of the updated RIA
and the agency will respond to all relevant comments received.

DATES: Comments must be received by November 1, 2017. Comments received
after that date will be considered to the extent practicable, provided
the comments do not result in additional delay or expense.

ADDRESSES: You may submit comments identified by the docket number
PHMSA-2017-0102 by any of the following methods:
     Federal eRulemaking Portal: http://www.regulations.gov.
Follow the online instructions for submitting comments.

SUPPLEMENTARY INFORMATION: On May 8, 2015, PHMSA, in coordination with
FRA, published a Final Rule adopting requirements designed to reduce
the consequences and, in some instances, reduce the probability of
accidents involving trains transporting large quantities of flammable
liquids. See 80 FR 26643. The Final Rule defined certain trains
transporting large volumes of flammable liquids as high-hazard
flammable trains (HHFT) \1\ and others as high-hazard flammable unit
trains (HHFUT).\2\ The Final Rule required HHFUTs transporting at least
one flammable liquid classified as a packing group I material be
operated with an ECP braking system by January 1, 2021, and all other
HHFUTs be operated with an ECP braking system by May 1, 2023. See 49
CFR 174.310(a)(3).
---------------------------------------------------------------------------

    \1\ The Final Rule defined an HHFT as ``a single train
transporting 20 or more loaded tank cars of a Class 3 flammable
liquid in a continuous block or a single train carrying 35 or more
loaded tank cars of a Class 3 flammable liquid throughout the train
consist.'' See 49 CFR 171.8.
    \2\ The Final Rule defined an HHFUT as ``a single train
transporting 70 or more loaded tank cars containing Class 3
flammable liquid.''
---------------------------------------------------------------------------

    In December 2015, Congress passed the FAST Act. Pub. L. 114-94, 129
Stat. 1686 (Dec. 4, 2015) (codified at 49 U.S.C. 20168). Section 7311
of the FAST Act (section 7311) established a process, including
independent study and testing, for DOT to use in developing an updated
RIA related to the Final Rule's ECP brake provision. The Secretary is
also required to solicit public comment on the revised RIA, and issue a
final updated RIA. Finally, Section 7311 requires the Secretary of
Transportation to review the final updated RIA and determine if the
final rule's ECP brake requirements are justified, based on whether the
final updated RIA demonstrates that the benefits exceed the costs. The
FAST Act requires this entire process to be completed no later than
December 4, 2017.
    Section 7311 required DOT to enter into an agreement with NAS to
test ECP brakes and reevaluate the economic analysis supporting the ECP
brake requirement of the Final Rule.\3\ Section

7311 required the testing to ``objectively, accurately, and reliably
measure[s] the performance of ECP brake systems relative to other
braking technologies or systems, such as distributed power and 2-way
end-of-train devices.'' The FAST Act also provided for GAO review of
the potential costs and benefits of ECP brakes. In response, GAO
completed an evaluation of the business benefits, safety benefits, and
costs that DOT estimated in the RIA for the final rule.\4\
Additionally, GAO recently completed a second evaluation comparing the
forecasted values of certain data points that were used to support
DOT's ECP brake analysis.\5\ Both audits are discussed in the updated
RIA.
---------------------------------------------------------------------------

    \3\ In a March 17, 2016, letter, NAS declined to perform the
testing, citing preliminary cost estimates to perform the testing in
excess of $100 million and expressing concern about meeting the
statutory deadline. As an alternative, to meet the intent of the
FAST Act, DOT conducted the testing itself and contracted with NAS
to review and monitor the test plan.

    PHMSA is providing the public with an opportunity to comment on the
updated RIA. To enable PHMSA to meet section 7311's deadline, all

section of this document by November 1, 2017. Comments received after
that date will be considered to the extent practicable, provided the
comments do not result in additional delay or expense. All documents
