(1) Study.--Not later than 1 year after the National
Academy of Sciences publishes the results of its study under
section 108 of the Ten-in-Ten Fuel Economy Act, the Secretary of
Transportation, in consultation with the Secretary of Energy and
the Administrator of the Environmental Protection Agency, shall
examine the fuel efficiency of commercial medium- and heavy-duty
on-highway vehicles and work trucks and determine--
``(A) the appropriate test procedures and
methodologies for measuring the fuel efficiency of such
vehicles and work trucks;
``(B) the appropriate metric for measuring and
expressing commercial medium- and heavy-duty on-highway
vehicle and work truck fuel efficiency performance,
taking into consideration, among other things, the work
performed by such on-highway vehicles and work trucks
and types of operations in which they are used;
``(C) the range of factors, including, without
limitation, design, functionality, use, duty cycle,
infrastructure, and total overall energy consumption and
operating costs that affect commercial medium- and
heavy-duty on-highway vehicle and work truck fuel
efficiency; and
``(D) such other factors and conditions that could
have an impact on a program to improve commercial
medium- and heavy-duty on-highway vehicle and work truck
fuel efficiency.
``(2) Rulemaking.--Not <<NOTE: Deadline.>> later than 24
months after completion of the study required under paragraph
(1), the Secretary, in consultation with the Secretary of Energy
and the Administrator of the Environmental Protection Agency, by
regulation, shall determine in a rulemaking proceeding how to
implement a commercial medium- and heavy-duty on-highway vehicle
and work truck fuel efficiency improvement program designed to
achieve the maximum feasible improvement, and shall adopt and
implement appropriate test methods, measurement metrics, fuel
economy standards, and compliance and enforcement protocols that
are appropriate, cost-effective, and technologically feasible
for commercial medium- and heavy-duty on-highway vehicles and
work trucks. The Secretary may prescribe separate standards for
different classes of vehicles under this subsection.
``(3) Lead-time; regulatory stability.--The commercial
medium- and heavy-duty on-highway vehicle and work truck fuel
economy standard adopted pursuant to this subsection shall
provide not less than--
[[Page 121 STAT. 1501]]
``(A) 4 full model years of regulatory lead-time;
and
``(B) 3 full model years of regulatory stability.''.
Bill Summary & Status - 110th Congress (2007 - 2008) - H.R.6 - CRS Summary - THOMAS (Library of Congress)
Directs the Secretary to study the fuel efficiency of work trucks and commercial medium-duty or heavy-duty on-highway vehicles to determine appropriate test procedures, methodologies, and metrics for measuring such efficiency.
