EPA on Penalties for On-Highway Heavy-Duty Diesel Engines
EPA is taking final action to make nonconformance penalties (NCPs) available to manufacturers of heavy heavy-duty diesel engines in model years 2012 and 2013 for emissions of oxides of nitrogen (NOX). In general, the availability of NCPs allows a manufacturer of heavy-duty engines (HDEs) whose engines fail to conform to specified applicable emission standards, but do not exceed a designated upper limit, to be issued a certificate of conformity upon payment of a monetary penalty to the United States Government. The upper limit associated with these NCPs is 0.50 grams of NOX
per horsepower-hour. The rule is effective January 31, 2012. Comments will be accepted until
April 4, 2012. http://www.gpo.gov/fdsys/pkg/FR-2012-01-31/html/2012-1937.htm
