Federal Highway Administration October 5, 2017 – Federal Register Recent Federal Regulation Documents

This NPRM follows a series of related rules that established a set of performance measures for State departments of transportation (State DOT) and Metropolitan Planning Organizations (MPO) to use as required by Moving Ahead for Progress in the 21st Century Act (MAP-21) and the Fixing America's Surface Transportation (FAST) Act. In the last of that series of rules, published on January 18, 2017, FHWA established a measure on the percent change in carbon dioxide (CO2) emissions from the reference year 2017, generated by on-road mobile sources on the National Highway System (NHS) (also referred to as the Greenhouse Gas (GHG) measure). Through this NPRM, FHWA proposes to repeal the GHG measure.
