In a series of workshops it’s conducting throughout the state, the California Air Resources Board says its considering a series of amendments to its off-highway emissions regulations, which it indefinately postponed in February.

Still lacking an EPA waiver that would allow them to enforce these rules — which were scheduled to start March 1st for large fleets — CARB says it may consider a two-year delay of the regulation start date, requiring large fleets to comply by March 1, 2012. An up to two-year compliance delay may also be possible for medium and small fleets.
