National Emissions Standards Act
From Wikipedia, the free encyclopedia
The Motor Vehicle Air Pollution Control Act is a 1965 amendment to the U.S. Clean Air Act of 1963. It set the first federal vehicle emissions standards beginning with the 1968 models (which were the same standards California had set for their 1966 models. These standards were reductions from the 1963 emissions: 72% reduction for hydrocarbons, 56% reduction for carbon monoxide, and 100% reduction for crankcase hydrocarbons. The impact on ambient air quality of future emissions standards and hypothetical vehicle fleet characteristics can be analyzed with the use of roadway air dispersion models.
