Rule Summary

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.
