Notice Type Title Summary of Notice NTP Information Cited CASRN
Final Rule Control of Air Pollution From Motor Vehicles: Tier 3 Motor Vehicle Emission and Fuel Standards This action establishes more stringent vehicle emissions standards and will reduce the sulfur content of gasoline beginning in 2017, as part of a systems approach to addressing the impacts of motor vehicles and fuels on air quality and public health. The gasoline sulfur standard will make emission control systems more effective for both existing and new vehicles, and will enable more stringent vehicle emissions standards. The vehicle standards will reduce both tailpipe and evaporative emissions from passenger cars, light-duty trucks, medium-duty passenger vehicles, and some heavy-duty vehicles. This will result in significant reductions in pollutants such as ozone, particulate matter, and air toxics across the country and help state and local agencies in their efforts to attain and maintain health-based National Ambient Air Quality Standards. Motor vehicles are an important source of exposure to air pollution both regionally and near roads. These vehicle standards are intended to harmonize with California's Low Emission Vehicle program, thus creating a federal vehicle emissions program that will allow automakers to sell the same vehicles in all 50 states. The vehicle standards will be implemented over the same timeframe as the greenhouse gas/fuel efficiency standards for light-duty vehicles (promulgated by EPA and the National Highway Safety Administration in 2012), as part of a comprehensive approach toward regulating emissions from motor vehicles.

Final Rule Diflubenzuron; Pesticide Tolerances This regulation establishes tolerances for residues of diflubenzuron (N-[[(4-chlorophenyl)amino]carbonyl]-2,6-difluorobenzimide) in or on fruit, citrus, group 10-10 and citrus, oil. Chemtura Corporation, requested these tolerances under the Federal Food, Drug, and Cosmetic Act (FFDCA).
