Title 40 published on 2011-07-01
The following are only the Rules published in the Federal Register after the published date of Title 40.
For a complete list of all Rules, Proposed Rules, and Notices view the Rulemaking tab.
EPA and NHTSA, on behalf of the Department of Transportation, are each finalizing rules to establish a comprehensive Heavy-Duty National Program that will reduce greenhouse gas emissions and fuel consumption for on-road heavy-duty vehicles, responding to the President's directive on May 21, 2010, to take coordinated steps to produce a new generation of clean vehicles. NHTSA's final fuel consumption standards and EPA's final carbon dioxide (CO 2 ) emissions standards are tailored to each of three regulatory categories of heavy-duty vehicles: Combination Tractors; Heavy-duty Pickup Trucks and Vans; and Vocational Vehicles. The rules include separate standards for the engines that power combination tractors and vocational vehicles. Certain rules are exclusive to the EPA program. These include EPA's final hydrofluorocarbon standards to control leakage from air conditioning systems in combination tractors, and pickup trucks and vans. These also include EPA's final nitrous oxide (N 2 O) and methane (CH 4 ) emissions standards that apply to all heavy-duty engines, pickup trucks and vans. EPA's final greenhouse gas emission standards under the Clean Air Act will begin with model year 2014. NHTSA's final fuel consumption standards under the Energy Independence and Security Act of 2007 will be voluntary in model years 2014 and 2015, becoming mandatory with model year 2016 for most regulatory categories. Commercial trailers are not regulated in this phase of the Heavy-Duty National Program. The agencies estimate that the combined standards will reduce CO 2 emissions by approximately 270 million metric tons and save 530 million barrels of oil over the life of vehicles sold during the 2014 through 2018 model years, providing over $7 billion in net societal benefits, and $49 billion in net societal benefits when private fuel savings are considered. EPA is also finalizing provisions allowing light-duty vehicle manufacturers to use CO 2 credits to meet the light-duty vehicle N 2 O and CH 4 standards, technical amendments to the fuel economy provisions for light-duty vehicles, and a technical amendment to the criteria pollutant emissions requirements for certain switch locomotives.
The following are ALL rules, proposed rules, and notices (chronologically) published in the Federal Register relating to 40 CFR 1039
The EPA is finalizing revisions to the standards of performance for new stationary compression ignition internal combustion engines under section 111(b) of the Clean Air Act. The final rule requires more stringent standards for stationary compression ignition engines with displacement greater than or equal to 10 liters per cylinder and less than 30 liters per cylinder, consistent with recent revisions to standards for similar mobile source marine engines. In addition, the action revises the requirements for engines with displacement at or above 30 liters per cylinder to align more closely with recent standards for similar mobile source marine engines, and for engines in remote portions of Alaska that are not accessible by the Federal Aid Highway System. The action also provides additional flexibility to owners and operators of affected engines, and corrects minor mistakes in the original standards of performance. Finally, the action makes minor revisions to the standards of performance for new stationary spark ignition internal combustion engines to correct minor errors and to mirror certain revisions finalized for compression ignition engines, which provides consistency where appropriate for the regulation of stationary internal combustion engines. The final standards will reduce nitrogen oxides by an estimated 1,100 tons per year, particulate matter by an estimated 38 tons per year, and hydrocarbons by an estimated 18 tons per year in the year 2030.
