REPORT:

Mobile Source Committee

SYNOPSIS:

The Mobile Source Committee met Friday, August 27, 1999. Following is a summary of that meeting. The next meeting will be September 24, 1999, at 9:35 a.m. in Conference Room CC-8.

RECOMMENDED ACTION:

Receive and file.

Cynthia Coad, Chair
Mobile Source Committee

Attendance

The meeting started at 9: a.m. Present: Committee Chairwoman Cynthia Coad, Committee Vice Chair Roy Wilson, and Committee Member Jon Mikels. Absent: Committee Members Norma Glover, Mee Hae Lee and Ron Loveridge. The attachment is an attendance roster.

ACTION/DISCUSSION ITEM:

1) Proposed Amendments to Rule 1186

Staff gave a presentation to the Committee on proposed amendments to Rule 1186. Revisions incorporate PM10-efficient street sweeper certification requirements and clarifications based on Rule 1186 Working Group and public comments.

Proposed amendments include:
• Requirement to use certified sweepers
• Requirement to maintain and operate certified sweepers
• Establishment of testing and certification procedures and test methods
• Definition of certification limits:
   - pick-up efficiency limit of 80%
   - maximum entrainment limit of 200 mg/m
• Definition of procurement and new contract/lease dates
• Removal of Rule1158 plan exemption

Staff also reported on the key implementation issues and responses, and outreach efforts and funding sources for local governments. One of the funding sources is the use of AB2766 subvention funds for any PM10-efficient sweeper cost differential. An AB2766 Technical Assistance Team has been formed by the AQMD to assist local governments obtain funding for their air quality programs, including Rule 1186 compliance.

The public hearing for this rule is September 1999.

Upon Committee Chairwoman Coad’s request, staff agreed to provide copies of research material on the health impacts of particulates.

INFORMATION ITEMS:

2) Rule 2202 Program Annual Status Report

Staff presented to the Committee the annual status report. SB432 permanently removed worksites of 100-250 employees from the rideshare regulation. As a result staff had to resolve the issue of making up for the emission reduction shortfalls. To assist with this effort an Emission Equivalency Task Force was formed. Staff analyses showed that during the period 1997-98 the emission reduction shortfalls were: VOC – 1.16 tons/day, NOx – 1.32 tons/day, CO – 11.95 tons/day. Staff explained that numbers of 1997 on the slide indicated the difference between the 1997 and 1998 shortfall and that the minutes would reflect the correct totals. The Emission Equivalency Task Force estimated during the period 2000-2010 the emission reduction shortfalls could reach a total of: VOC – 1.28 tons/day, NOx – 2.33 tons/day, CO – 17.1 tons/day.

To make up for the shortfalls, the Emission Equivalency Task Force put forward the following recommendation of priorities for utilizing reductions:

• MSRC NOx credits
• AQIP Overage
• Carl Moyer Program
• ERC Donations
• Provide information on Parking Management
• Forward revision concept to the AQMP Advisory Committee for discussion

In addition staff reported on the following: Rule 2202 program activity changes; total emission reductions resulting from the Air Quality Investment Program since its inception; outreach efforts; technical assistance team efforts and results; and compliance result. Staff also advised the Committee of the compliance rate: during the year 1998 788 compliance audits were conducted; 191 Notices to Comply and 7 Notices of Violation were issued.

Staff commented that the Rule 2202 continues to be a successful
program, and advised that an annual report will again be presented next year.

At approximately 10:05 a.m. the video-conferencing connection with Vice Chair Wilson’s office in Indio was cut off due to problems with the phone system. As a result, Vice Chair Wilson’s participation in the meeting was discontinued at that time. Staff will brief Vice Chair Wilson on any items that he requests.

3) Report on E.J. Initiative #2 – Ambient Monitoring of Air Toxics

The MATES II and Microscale monitoring program is now completed and staff presented to the Committee the final monthly report. Staff reported that all field sampling and laboratory analyses are completed, and all data (from both AQMD and ARB laboratories) are compiled into the data base. Final activities in progress include: quality assurance of data base; analyses of data, regional toxics modeling and assessment; and preparation of final report.

Staff also presented to the Committee a preliminary analysis of network average cancer risks from air toxics, which shows an overall risk level of 1505 in one million (in population). The analysis was based on data collected from 10 locations over a one-year period; and ARB’s methodology and risk value were used for the diesel component. The analysis shows that the major contributor to the overall risk is diesel particulate (72%). The other two key contributors are: 1,3 Butadiene (10%) and Benzene (6%). All these are mobile source pollutants. This means that stationary source pollutants account for roughly 12% of the total risk.

In closing, staff reported that in September 1999 data analyses and modeling will be completed and the draft final report will be provided to the Technical Review Group for review. In November 1999 the Mates II and Microscale Study results will be presented to the Governing Board and the final report released to the public.

4) Air Toxics Reduction Plan

Staff reported that to fully implement Environmental Justice Initiative #10, the AQMD is proposing an Air Toxics Reduction Plan, a comprehensive short- and long-term control strategy which will outline efforts to reduce air toxic exposures in the Basin. At the September Governing Board meeting, staff will outline the concept and seek Board direction on whether to proceed with development of the Plan. Analyses of relative toxic contribution were presented. One analysis, which did not include diesel particulate toxicity, shows the following ratio: On-Road – 45%; Stationary – 33%; and Off-Road – 22%. The other analysis included diesel particulate and was already presented under Item #3 above.

During the process of development of this plan extensive public participation will be sought and it is staff’s intent to return to the Board within six months with the comprehensive Air Toxics Reduction Plan. However, this schedule may be affected by the pending AQMP litigation.

5) Report on the July 22 Meeting of the Ad Hoc Committee to Review Air Quality Impacts of Airport and Marine Port Operations

Staff advised the Committee that the purpose of this Committee is to track airport and marine port related activities that may have potential air quality impacts and that the Committee was reconvened with the inclusion of the Alameda Corridor project. Topics discussed at the July 22, 1999 meeting were:

• U.S. EPA public consultative process
• Special monitoring program at LAX
• Status report on LAX airport expansion and El Toro reuse.

Issues raised at the meeting covered:

• EPA’s or FAA’s ability to target cleaner aircraft for the South Coast region
• Federal policies on diesel usage
• Need to collect measurements at the lower terminal levels at LAX
• AQMD authority over ground access, GSE, and APUs
• Lack of environmental analysis at LAX

Based on discussions at the meeting, following action items are proposed:

• Discuss with LAX on collecting ambient data at the lower terminal levels
• District Counsel to address legal authority over certain types of off-road equipment at the airports
• Address concerns regarding prior project approvals and CEQA at LAX
• As part of Alameda Corridor discussions, include impacts on rail operations in
North Orange County.

The next meeting of the Committee is scheduled for September 23, 1999.
