This Notice provides an opportunity to comment on new information being made available by the EPA and by NHTSA, on behalf of DOT, related to the proposed Phase 2 Heavy-Duty National Program proposed July 13, 2015, to reduce greenhouse gas emissions and fuel consumption for new on-road heavy-duty vehicles and engines. The new information, including memoranda and data, have been placed in the public dockets. Data relating to the potential stringency of the proposed standards includes: Powertrain data; additional aerodynamic test data; supplemental test data relating to drive cycles (and frequency thereof) for vocational vehicles; and cycle average mapping data. The agencies are soliciting additional comment on certain revised test reports, and a revised version of the Greenhouse Gas Emission Model (GEM) used both in developing certain of the proposed standards and in demonstrating compliance with those standards. Additionally, EPA is soliciting further comment on memoranda relating to standard applicability and implementation. These memoranda address potential requirements for selective enforcement audits and confirmatory testing related to greenhouse gas emissions, and applicability of emission standards and certification responsibilities for trailers, glider vehicles, and glider kits. Finally, EPA is soliciting additional comments on issues discussed in a late comment related to light-duty motor vehicles used for racing.
