United States Government Publishing Office publisher pbl distributor dst United States National Archives and Records Administration Office of the Federal Register author aut Government Organization text government publication eng FR Regulatory Information 2016_register executive 2018-02-13 article Part II Rules and Regulations D09002ee1c7f346d1 D09002ee1c7f34789 United States Environmental Protection Agency originator org United States Government Agency or Subagency EPA and NHTSA, on behalf of the Department of Transportation, are establishing rules for a comprehensive Phase 2 Heavy-Duty (HD) National Program that will reduce greenhouse gas (GHG) emissions and fuel consumption from new on-road medium- and heavy-duty vehicles and engines. NHTSA's fuel consumption standards and EPA's carbon dioxide (CO<INF>2</INF>) emission standards are tailored to each of four regulatory categories of heavy-duty vehicles: Combination tractors; trailers used in combination with those tractors; heavy-duty pickup trucks and vans; and vocational vehicles. The rule also includes separate standards for the engines that power combination tractors and vocational vehicles. Certain requirements for control of GHG emissions are exclusive to the EPA program. These include EPA's hydrofluorocarbon standards to control leakage from air conditioning systems in vocational vehicles and EPA's nitrous oxide (N<INF>2</INF>O) and methane (CH<INF>4</INF>) standards for heavy-duty engines. Additionally, NHTSA is addressing misalignment between the Phase 1 EPA GHG standards and the NHTSA fuel efficiency standards to virtually eliminate the differences. This action also includes certain EPA- specific provisions relating to control of emissions of pollutants other than GHGs. EPA is finalizing non-GHG emission standards relating to the use of diesel auxiliary power units installed in new tractors. In addition, EPA is clarifying the classification of natural gas engines and other gaseous-fueled heavy-duty engines. EPA is also finalizing technical amendments to EPA rules that apply to emissions of non-GHG pollutants from light-duty motor vehicles, marine diesel engines, and other nonroad engines and equipment. Finally, EPA is requiring that engines from donor vehicles installed in new glider vehicles meet the emission standards applicable in the year of assembly of the new glider vehicle, including all applicable standards for criteria pollutants, with limited exceptions for small businesses and for other special circumstances. 81 FR 73478 https://www.govinfo.gov/app/details/FR-2016-10-25/2016-21203 2016-21203 fr25oc16-9 RIN 2060-AS16 RIN 2127-AL52 6560-50-P EPA-HQ-OAR-2014-0827 NHTSA-2014-0132 FRL-9950-25-OAR https://www.govinfo.gov/app/details/FR-2016-10-25/2016-21203 https://www.govinfo.gov/content/pkg/FR-2016-10-25/html/2016-21203.htm https://www.govinfo.gov/content/pkg/FR-2016-10-25/pdf/2016-21203.pdf Environmental Protection Vessels Administrative Practice and Procedure Air Pollution Control Hazardous Substances Hazardous Waste Penalties Pesticides and Pests Poison Prevention Water Pollution Control Electric Power Fuel Economy Confidential Business Information Imports Labeling Motor Vehicle Pollution Research Warranties Incorporation by Reference Reporting and Recordkeeping Requirements Motor Vehicles 797 p. 73478 74274 81 FR 73478 Title 40 Part 1033 40 CFR Part 1033 Title 40 Part 1036 40 CFR Part 1036 Title 40 Part 1037 40 CFR Part 1037 Title 40 Part 1039 40 CFR Part 1039 Title 40 Part 1042 40 CFR Part 1042 Title 40 Part 1043 40 CFR Part 1043 Title 40 Part 1065 40 CFR Part 1065 Title 40 Part 1066 40 CFR Part 1066 Title 40 Part 1068 40 CFR Part 1068 Title 40 Part 22 40 CFR Part 22 Title 40 Part 600 40 CFR Part 600 Title 40 Part 85 40 CFR Part 85 Title 40 Part 86 40 CFR Part 86 Title 40 Part 9 40 CFR Part 9 Title 49 Part 523 49 CFR Part 523 Title 49 Part 534 49 CFR Part 534 Title 49 Part 535 49 CFR Part 535 Title 49 Part 538 49 CFR Part 538 RIN 2060-AS16 RIN 2127-AL52 Greenhouse Gas Emissions and Fuel Efficiency Standards for Medium- and Heavy-Duty Engines and Vehicles-Phase 2; Federal Register Vol. 81, Issue RULE 2016-21203 II ENVIRONMENTAL PROTECTION AGENCY 2016-12-27 EPA-HQ-OAR-2014-0827 NHTSA-2014-0132 FRL-9950-25-OAR 6560-50-P 2016-21203 Final rule.

EPA and NHTSA, on behalf of the Department of Transportation, are establishing rules for a comprehensive Phase 2 Heavy-Duty (HD) National Program that will reduce greenhouse gas (GHG) emissions and fuel consumption from new on-road medium- and heavy-duty vehicles and engines. NHTSA's fuel consumption standards and EPA's carbon dioxide (CO<INF>2</INF>) emission standards are tailored to each of four regulatory categories of heavy-duty vehicles: Combination tractors; trailers used in combination with those tractors; heavy-duty pickup trucks and vans; and vocational vehicles. The rule also includes separate standards for the engines that power combination tractors and vocational vehicles. Certain requirements for control of GHG emissions are exclusive to the EPA program. These include EPA's hydrofluorocarbon standards to control leakage from air conditioning systems in vocational vehicles and EPA's nitrous oxide (N<INF>2</INF>O) and methane (CH<INF>4</INF>) standards for heavy-duty engines. Additionally, NHTSA is addressing misalignment between the Phase 1 EPA GHG standards and the NHTSA fuel efficiency standards to virtually eliminate the differences. This action also includes certain EPA- specific provisions relating to control of emissions of pollutants other than GHGs. EPA is finalizing non-GHG emission standards relating to the use of diesel auxiliary power units installed in new tractors. In addition, EPA is clarifying the classification of natural gas engines and other gaseous-fueled heavy-duty engines. EPA is also finalizing technical amendments to EPA rules that apply to emissions of non-GHG pollutants from light-duty motor vehicles, marine diesel engines, and other nonroad engines and equipment. Finally, EPA is requiring that engines from donor vehicles installed in new glider vehicles meet the emission standards applicable in the year of assembly of the new glider vehicle, including all applicable standards for criteria pollutants, with limited exceptions for small businesses and for other special circumstances.
