(a) The trigger level requirement.

(b) Yearly projections regarding the trigger level. For each year, the executive officer shall identify any designated clean fuels he or she projects will for the first time be the fuel for a sufficient number of low-emission vehicles to reach the trigger level set forth in section 2303.5(a). At least sixteen months before the start of the year, the executive officer shall notify interested parties of the fuel or fuels identified, and shall make available a summary of the information and analysis relied upon, including the fleet discount factor applied. The notification shall also identify any other designated clean fuel that the executive officer projects will miss the trigger level by no more than 30 percent, with the information and analysis relied upon being made available. The notice shall be provided to trade associations representing gasoline refiners, distributors and retailers, representative environmental groups, and any person who has requested in writing to receive such notices.

(c) Requests to revise trigger level projections. Any interested party may request in writing that the executive officer revise the trigger determination or fleet discount factor for any designated clean fuel, and may submit any relevant information supporting a revised determination. In order to be considered by the executive officer, the written request and supporting information must be received no more than 30 days after issuance of the notice. The executive officer shall consider any requests that are timely submitted, and shall issue his or her final trigger determination and fleet discount factor no less than fourteen months before the start of the year in question.
