In a February 22 letter, AWO President & CEO Jennifer Carpenter asked California Governor Gavin Newsom to delay deadlines or enforcement of the California Air Resources Board (CARB) Commercial Harbor Craft Rule due to safety issues and lack of the EPA-required authorization. Jennifer pointed out that technical experts have not approved diesel particulate filters (DPFs) for safe use in towing vessels and that CARB has failed to take into consideration the repeated concerns maritime and labor organizations have expressed about DPFs.
