INFORMATION ITEMS

1. Review of Mobile Source-Related Rule Development
   Staff gave a briefing on mobile source-related rule development for next year. Four existing rules are to be amended: Rule 1631 - Marine Vessels; Rule 1632 - Hotelling Operations; Rule 1633 - Truck/Trailer Refrigeration Units; and Rule 2507 - Agricultural Pumps. Several new credit generation rules are proposed: Proposed Rule 1635 - Construction Equipment; Proposed Rule 1636 - Ground Support Equipment; and Proposed Rule 1637 - Trains. Proposed Rule 1635 includes repowering diesel equipment such as scrapers and bulldozers. Staff will evaluate credits for PM, CO, and SOx. Proposed Rule 1636 includes equipment at airports not covered by an MOU and would involve replacing diesel equipment with electric. Staff will evaluate PM, CO, and NOx credits for cargo loaders, baggage and aircraft tractors, belt loaders, and other equipments. Proposed Rule 1637 includes local trains. The technology would include new LNG engines and particulate traps. PM & NOx credits will be evaluated. Working groups and the HRAG credit subcommittee will discuss these issues and work with staff on the rule development. Staff is also working closely with U.S. EPA and CARB. The key focus is to determine surplus credits and quantification methods. The schedule is for amendments to existing rules in the second quarter of 2003 and new rules in the third and fourth quarter.

2. Report on Updated Mira Loma Study
   Staff gave a presentation on the analysis conducted by the AQMD to assess the impact of diesel particulate emissions from warehouse / distribution centers in Mira Loma area. The analysis, which was recently presented to the Riverside County Planning Commission, delineated that additional warehouse traffic cause increase in cancer risk due to the diesel exhaust from the trucks. Mitigation measures to reduce the risks have been introduced, and incorporated into the analysis.

3. Report on Proposed Amended Rule 1610
   This brief report updates the Mobile Source Committee on staff's conclusions and findings regarding three major issues raised during the public comment period on this proposal. First, proposed eligibility and inspection requirements are now exactly the same as those of the CARB VAVR. Second, staff reports that CARB intends that eligible vehicles be driven to the inspection site on the entire distance the day of the functional inspection. Staff will continue to work with CARB to assure that implementation of the rule conforms with CARB's intent. Third, staff will confirm to the Committee that CARB staff have submitted the rule to the State Office of Administrative Law. The submittal requests an effective date of January 3, 2003 to allow timely implementation statewide. During discussion of issues relating to whether vehicles donated to charity could be accommodated in the rule, committee members requested staff to assure the same level of enforcement (i.e., inspect each vehicle and observe it driving) for charity vehicles as is currently done for vehicles in the program.

4. Report on EJ Enhancement #III-1
   Rule Development - Off-Road Intermodal Equipment
   The proposed rule on intermodal equipment is being developed to implement one of the Environmental Justice Enhancements adopted by the Board in September 2002. Enhancement III-1 calls for the development of a rule to reduce diesel emissions from off-road equipment such as yard hostlers at port facilities, railroad yards, and distribution centers. AQMD staff is currently evaluating the extent of the AQMD's legal authority to regulate intermodal equipment. Regulatory options may include: fleet rule approach for on-road vehicles, retrofit of existing off-road vehicles, and limitation on usage.
   
   Based on a preliminary analysis, there are approximately 600-yard hostlers operating at railroad yards and the Ports of Long Beach and Los Angeles. The majority of yard hostlers are diesel powered and range in size from 150 to 200 horsepower and operate 8 to 10 hours per day. Additional population and activity data will be collected from ports and rail yards. Staff will also conduct a technology assessment to identify feasible control technologies and methods to reduce emissions from diesel-powered intermodal equipment (e.g., alternative fuels and particulate traps). The proposed rule on intermodal equipment is scheduled for adoption in July 2003.
