The Environmental Protection Agency issued a direct final rule on April 3, with a corresponding proposed rule that updates its gasoline and diesel fuels programs regulations on several test method issues.  This rule ensures that certain fuel testing requirements are more up-to-date by having refiners and laboratories use the most current versions of American Society for Testing and Materials Committee D.02 analytical test methods.  Together, these rules will allow improvements in the test method procedure to ensure better operation and provide additional flexibility to the regulated community.  This direct final rule is effective June 2, 2006, unless EPA receives adverse comments or a request for public hearing by May 3, 2006.
