EPA Expected to Issue Strict New Diesel Rules
The Environmental Protection Agency is expected to soon issue new rules that will severely restrict the amount of pollution that will be allowed in the exhaust of diesel engines. And the changes could result in sharp price increases and dramatically diminished supplies of the fuel.
The proposed rule is expected no sooner than mid-April, industry analysts said, and will come after a spirited lobbying campaign by the oil industry, engine makers and environmentalists to influence EPA’s decision.
At present, diesel engines may emit up to 500 parts per million of sulfur in their exhaust. The oil industry has lobbied for a standard of no less than 50 ppm, while engine manufacturers and environmentalists would like to see the standard set as low as possible.
