EPA Sets Penalties for Polluting Diesel Engines

WASHINGTON (CN) - The Environmental Protection Agency has set non-conformance penalties for heavy-duty diesel engines that cannot meet 2010 emission standards.

Non-conformance penalties allow manufacturers to pay a set fine on every engine they manufacture that does not meet a particular emission standard rather than stop making the engines.

The penalties are created on an as needed basis when the EPA thinks it is likely that a manufacturer will fail to meet a standard that has recently become tougher, for technological reasons.

This year the agency created non-conformance penalties for emissions of oxides of nitrogen (NOx) because it believes at least one manufacturer of heavy-duty diesel engines will not meet the standard in model years 2012 and 2013.

Penalties are set on a sliding scale depending on the level of NOx emissions falling outside the standard. The penalty per engine tops out at around $2,000 for engines that emit .50 grams per brake-horsepower-hour.

The penalties increase over time to encourage manufacturers to develop or acquire technology that will bring their engine emissions into compliance.
