Air Quality and Motor Vehicles: An Analysis of Current and Proposed Emission Standards
The extent to which emissions from motor vehicles and the amount of sulfur in commercial gasoline should be regulated has become a controversial issue. The EPA is proposing national limits on gasoline sulfur levels which would become effective in 2004. This report provides background information on the regulation of vehicle emissions in the United States, analyzes key elements of the National Low Emission Vehicle (LEV) program and the Environmental Protection Agency's (EPA) Tier 2 proposal, summarizes major views on the proposal that have been expressed by the automobile industry, the oil refining industry, and some environmental organizations, and discusses relevant legislative activity in the 106th Congress. digital.library.unt.edu/ark:/67531/metacrs849/
Air Quality and Vehicle Emission Standards: An Overview of the National Low Emission Vehicle Program and Related Issues
This report provides background information on federal emission standards for motor vehicles under the Clean Air Act and stricter standards originally developed to address the severity of air quality problems in California, explains the low emission standards and flexible compliance mechanisms to which states and manufacturers have voluntarily agreed under the National Low Emission Vehicle (LEV) Program, discusses the Environmental Protection Agency's (EPA) estimates of the program's air quality benefits and costs, and examines regulatory issues related to its implementation including sulfur levels in gasoline and the relative stringency of emission standards for light trucks. digital.library.unt.edu/ark:/67531/metacrs845/
