Continuation of the July 30, 1998, public hearing to consider the Staff proposal to identify diesel exhaust as a toxic air contaminant, under the AB 1807 TAC program (Health and Safety Code Section 39650 et seq., Food and Agriculture Code Section 14021 et seq.).

The California Clean Air Act requires that districts submit to the Air Resources Board (ARB) a triennial progress report that includes information on air quality improvements and the expected and revised emissions reductions for each district measure scheduled for adoption in the previous three year period. The ARB staff will present their findings with respect to the triennial progress reports submitted by the districts and provide recommendations for ARB approval.

Amendments to the California Cleaner-burning Gasoline Regulations are proposed to increase the cap limit for oxygen from 2.7 percent to 3.5 percent by weight and to eliminate the winter time requirement for a minimum oxygen content in carbon monoxide attainment areas. Other minor technical amendments are proposed.

The On-board Refueling Vapor Recovery (ORVR) compatibility and air liquid (A/L) test procedures presented at the May meeting will be deferred until the December Board meeting. The Board will consider the adoption of the remaining proposed revisions: add a temporary exemption from annual venting controls for airport refueler cargo tanks, add a "tie-tank" test procedure to ensure system plumbing is correct, and various changes to improve clarity and safety of test procedures.

The proposal revises 20 existing stationary source test methods to make them more compatible with applicable U.S. Environmental Protection Agency (U.S. EPA) test methods. To provide more consistent emission testing statewide, staff is proposing that test method modifications be approved by the Air Resources Board (ARB) Executive Officer and not the district. Even though there are comparable U.S. EPA test methods, ARB test methods 1) contain necessary additional provisions not found in U.S. EPA test methods (e.g., excess air determination in Method 3), 2) are referenced in District rules, and 3) are used as defaults when no district test methods are referenced.

Proposal Number 2375-205 entitled "Demonstration of a Fast-Response On-Board NO_x Sensor for Heavy-Duty Diesel Vehicles," submitted by Southwest Research Institute, for a total amount not to exceed $348,133.

Proposal Number 2380-205 entitled "Heavy-Duty Gasoline Truck Evaporative Emissions Testing for Emissions Inventory," submitted by Automotive Testing Laboratories, Inc., for a total amount not to exceed $128,690.

Proposal Number 2381-205 entitled "Development of 'Hot Spots' Analysis and Reporting Program (HARP) Risk Analysis Module," submitted by Dillingham Software Engineering, Inc., for a total amount not to exceed $99,977.

Proposal Number 2384-205 entitled "Particulate Air Pollution and Cardiovascular Morbidity," submitted by the University of California, Davis, for a total amount not to exceed $199,480.

Proposal Number 2382-205 entitled "Ambient Ozone Patterns and Ozone Injury Risk to Ponderosa and Jeffrey Pines in the Sierra Nevada," submitted by USDA Forest Service, for a total amount not to exceed $77,569.

Proposal Number 2385-205 entitled "Improvement of Speciation Profiles for Aerosol Coatings," submitted by California Polytechnic State University, San Luis Obispo, for a total amount not to exceed $28,885.

Staff is recommending appointments to the Board's Research Screening Committee. This Committee reviews and recommends air pollution research projects to the Board. These appointments will fill current vacancies on the Committee.
