Rule Summary

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.

The U.S. Environmental Protection Agency (EPA) is finalizing nonconformance penalties that could be used by manufacturers of heavy-duty diesel engines unable to meet the 2004 model year non-methane hydrocarbon plus nitrogen oxides (NMHC+NOx) emission standard. These penalties allow a manufacturer to produce and sell nonconforming engines upon payment of a penalty. The penalty, which is assessed on a per-engine basis, varies with the certified emission level for the engine family involved.
