Report to the Board on a Health Update - Traffic-Related Air Pollution near Busy Roads: The East Bay Children's Respiratory Health Study  
  The Office of Environmental Health Hazard Assessment (OEHHA) recently conducted a school-based cross-sectional epidemiological study to examine the associations between proximity to traffic and respiratory health among children living and attending schools at varying distances from high-traffic roadways in Alameda County, CA. Most of these children are nonwhite and of lower socioeconomic status. Outdoor concentrations of nitrogen oxides (NOx), nitric oxide (NO), and black carbon (BC) measured at neighborhood schools were used as surrogates for children's overall exposure to traffic pollutants. The study found associations between traffic pollution and increased asthma and bronchitis symptoms. This study is one of the first in the U.S. to examine the relationships between measured traffic-related pollutants and respiratory symptoms in children.

Report to the Board on the In-Vehicle Exposures: Implications for Exposure Assessment  
  Exposure to vehicle-related pollutants-both near-traffic and inside vehicles-are beginning to be linked to health outcomes, such as the recent study associating driving time with increased risk of heart attack. An overview of in-vehicle measurements and exposures for California will be presented. These measurements show that time in vehicles (about 6% a day on average) results in a major fraction of a person's total daily exposure, ranging from about 15% for benzene, to 30 to 55% for diesel PM, and even higher for ultrafine particles.

Public Hearing to Consider the Proposal of the Airborne Toxic Control Measure to Reduce Emissions of Hexavalent Chromium and Nickel from Thermal Spraying  
  Staff will propose a new Airborne Toxic Control Measure (ATCM) to reduce emissions of hexavalent chromium and nickel from thermal spraying operations. This ATCM establishes emission standards for hexavalent chromium and nickel for thermal spraying operations at stationary sources that use materials containing chromium or nickel. The ATCM also requires monitoring, recordkeeping, and reporting.

Public Hearing to Consider Amendments to the California Off-Road Emissions Regulation for Compression-Ignition Engines and Equipment  
  Staff is proposing to amend California's existing off-road compression-ignition (diesel) engine regulations to harmonize with the U.S. EPA requirements as set forth on June 29, 2004. The standards proposed for the Tier 4 engines, which begin with the 2008 model year, represent aftertreatment-based levels to reduce engine out NOx and PM emissions by 90 percent. The proposed Tier 4 standards are equivalent to the California 2007 on-road heavy-duty engine standards. The staff's proposal also supplements the federal rule by requiring more descriptive labeling and certification requirements to improve the implementation of the regulations.

Public Meeting to Update the Board on the Heavy-Duty Diesel Engine Voluntary Software Upgrade (Chip Reflash) Program Update  


Staff will present data on the status and sustainability of a voluntary program to reflash (reprogram the electronic controls of) 1993-1999 model year heavy-duty diesel trucks. The Board will evaluate whether to continue the voluntary program or to direct staff to implement a mandatory program by filing the regulation approved by the Board in March 2004.

Public Meeting to Update the Board on Air Quality  
  ARB staff will make a presentation on the progress that has been achieved in reducing exposure to unhealthy air and meeting State and federal standards. The presentation will cover ozone, particulate matter, and toxic air contaminants, and will look at how 2004 air quality compares to previous years.
