Counts oil derived from tar sands (and certain other specified feedstocks or finished fuel products that meet statutory tests) as “crude oil” for purposes of federal excise taxes. It also gives the Secretary of the Treasury (or the Secretary’s delegate) authority to treat additional fuel feedstocks or finished fuel products as crude oil or petroleum products for the tax when they meet tests tied to the Oil Pollution Act of 1990 and commercial production.

Makes a small technical correction to an existing paragraph of the Internal Revenue Code and says the change takes effect on the date the Act is enacted. The change mainly affects how certain nontraditional oils are classified for federal fuel excise-tax rules and gives Treasury discretionary authority to extend that classification to other fuels that meet specified tests.
