SUMMARY:

On June 2, 2000, the U.S. Environmental Protection Agency (EPA or Agency) published a Notice of Proposed Rulemaking (NPRM) (see 65 FR 35430) proposing changes to standards for heavy-duty engines and sulfur fuel controls for highway diesel fuel. In the preamble of the June 2, 2000, NPRM we proposed to apply to heavy-duty highway engines and vehicles “not to exceed” (NTE) and supplemental steady state test provisions which were published as a proposed rule on October 29, 1999 (64 FR 58472) “Control of Emissions of Air Pollution from 2004 and Later Model Year Heavy-Duty Highway Engines and Vehicles; Revision of Light-Duty On-Board Diagnostics Requirements'' (2004 Rule).

The 2004 Rule was recently signed on July 31, 2000 but has not yet been submitted for publication in the Federal Register. To allow commenters as much time as possible to comment on the June 2, 2000, NPRM before the end of the comment period, the Agency is making the signed version of the 2004 Rule available on an EPA website listed in ADDRESSES. The end of the comment period for the June 2, 2000, NPRM is August 14, 2000.
