Commercial Harbor Craft ACE Overview:
The Commercial Harbor Craft regulation (CHC regulation) allows the Air Resouces Board (ARB) Executive Officer to approve an alternative contol of emissions (ACE) compliance strategy provided the owners/operators can demonstrate that the alternative strategy will achieve diesel particulate matter (PM) and oxides of nitrogen (NOx) emission reductions equal to or greater than those required by the regulation.  Alternative strategies can include, but are not limited to, engine modifications, exhaust after-treatment control, engine repower, use of alternative fuels or fuel additives, or fleet averaging.  ACE applications are made available for public review and comment in two separate public comment periods prior to final approval by the Executive Officer.  The owner or operator is required to meet the performance requirements in the CHC regulation until Executive Officer approval is granted.
