CARB tells Navistar its engine pollution credits could soon run out

A CARB spokesman said future action by the board will depend on what Navistar’s plans for future engines are.

The California Air Resources Board (CARB) has issued an executive order informing Navistar that its pollution credits allowing it to sell heavy-duty engines not in compliance with the most recent environmental standards are nearly used up.

A CARB spokesman said future action by the board will depend on what Navistar’s plans for future engines are.

According to the executive order issued by CARB on the status of its credits, “ … based on the manufacturer's statement of credit balance and projected production, the model year for purposes of production under this Executive Order expires on February 29, 2012. This Executive Order only covers engines produced on or before February 29, 2012.”

Navistar spokeswoman Karen Denning said, “Navistar remains confident in our EGR strategy and will be submitting a .2 engine for certification very soon.  We will be discussing more at our Analyst and Investor Day on February 2nd.“

Fines could be levied against Navistar if the engine maker doesn’t come up with compliant pollution-reduction technology to meet federal nitrogen oxide standards before its credits are used up.





A federal district judge in Washington last week dismissed Navistar’s lawsuit challenging the federal Environmental Protection Agency’s (EPA) approval of Navistar’s competition’s engine technology, selective catalytic reduction or SCR. All engine makers in the U.S. with the exception of Navistar use SCR and SCR has already been used in Europe extensively.

Navistar opted for exhaust gas recirculation or EGR, which doesn’t reduce nitrogen oxide enough to meet EPA’s latest standards. However, Navistar had credits stored up from earlier engines exceeding federal emissions rules.

Navistar had maintained that SCR engines should be recalled because they could still be operated if the SCR system had been dismantled.

Judge Colleen Kollar-Kotelly said the EPA and truck manufacturers can’t be held accountable for deliberate misuse of the SCR system.
