The California Air Resources Board staff invites the public to participate in a Commercial Harbor Craft workshop on February 16, 2010, from 9:30 a.m. to 11:30 a.m. in Sacramento (and via webcast). At the meeting, staff will present draft amendments to the regulation to add in-use engine requirements for diesel engines on dredges, barges, and crew and supply boats which operate in Regulated California Waters. Additionally, draft amendments to address implementation issues and to clarify regulatory language will be discussed. Staff will also present updates to the harbor craft emissions inventory and provide information on the economic impacts related to these amendments.
