Marine Vessel Projects

Marine vessel project types include engine repower and shore power. Each category is summarized below.

Marine Engine Repower:

Marine vessels not subject to the in-use compliance requirements of CARB’s Commercial Harbor Craft Regulation such as fishing vessels, pilot boats and work boats are eligible for funding under the Carl Moyer Program (CMP).  Vessels subject to the in-use compliance requirements of CARB’s Commercial Harbor Craft (CHC) regulation (i.e., barge, crew/supply, dredge, excursion, ferry, towboat and tugboats) are also eligible as long as the vessel is fully compliant with the CHC Regulation (i.e., engines meet Tier 2 standards). Based on the vessel’s operation, the newer engine’s emissions must be surplus to the currently required U.S. EPA marine engine emission standard (i.e., Tier 3, Tier 4, etc.).

Shore Power (Ship Side) Projects:

Limited CMP funding opportunities remain for shore power projects due to the applicability of CARB’s At-Berth Regulation.  Applicants must submit their CARB-approved Initial Terminal Plan to document compliance with CARB’s Shore Power regulation.  The proposed project must provide emission reductions that are surplus to regulatory requirements.  Projects not subject to CARB’s regulation are eligible.
