EPA restricts sulfur in gas to cut auto emissions
By Neela Banerjee, Los Angeles Times
WASHINGTON — The Environmental Protection Agency issued final rules Monday to slash the amount of sulfur in gasoline, which would help cut smog-causing pollution from autos and bring the rest of the country’s fuel supply in line with California’s standards.
The new rule for “Tier 3” gasoline calls for reducing the amount of sulfur in fuel by two-thirds, to 10 parts per million from 30 parts per million. Similar low-sulfur gasoline is already in use in California, Europe, Japan and South Korea.
The new gasoline would be available at the pump by January 2017.
