Overview
• Community Air Risk Evaluation (CARE) Program
• CARE Mitigation Action Plan
• Multi-pollutant Clean Air Plan
• Cumulative Impacts Resolution

Regulatory Authority• Regional Air Pollution
Control Agencies – Primary regulatory authority
over stationary sources
• State Air Resources Board– Intrastate mobile sources—
cars, trucks, cargo handling equipment
• U.S. EPA– Interstate mobile sources—
trains, aircraft & ocean going vessels

CARE Program Objectives
• Evaluate regional and community cancer and non-cancer health risk from ambient toxic air contaminants
• Identify sensitive populations
• Focus health risk mitigation measures on locations with higher risk levels and sensitive populations

• Bay Area average cancer risk from air pollutants is decreasing
• BUT, risk in some locations is high compared to average
• AND health studies suggest that age and income affect sensitivity to air pollution

CARE Mitigation Action Plan
• Focus risk reduction activities where they are most needed
• Based on maps of toxic air emissions and sensitive populations, six impacted communities were identified
– Grant funds– Outreach efforts– Liaison with local health &
planning departments– Land use guidance– Green Ports Initiative

• Meet with community members in impacted areas to seek input on projects to fund
• Provide community-specific information on toxic air contaminants and emission reductions
Community Outreach
• Hear community concerns
• Collaborate on local-scale studies
December 4, 2008 14
Land Use Guidance
• Cities and counties have authority over local land-use decisions
• Land-use guidance will help cities and counties– Evaluate health impact resulting from new
development projects– Assess the health impact to new development
projects from existing toxic sources– Determine when mitigation is required and identify
possible measures and their effectiveness– Assist with general plans and project-specific analysis– Provide tool for more informed local decision making
December 4, 2008 15
Land Use Issues• New infill development projects in impacted communities
• Potential conflict between residential developments and freeways, busy roads, and other sources of diesel emissions
– Need health protective land use planning
• Opportunities for collaboration
– Example: Oakland Army Base
December 4, 2008 16
2009 Clean Air Plan
• Update 2005 Ozone Strategy • Consider multiple pollutants in an integrated plan
- Ozone- Particulate matter- Toxic air contaminants- Greenhouse gases
• Improve air quality & protect public health• Protect our climate• Regional plan will provide local air quality benefits
December 4, 2008 17
Address community concerns Air District Board Adopted Resolution (July 30, 2008)
– Continue to address cumulative impacts– CARE Mitigation Action Plan– Continue to explore additional options
Next Steps: CARE Working Group– Develop recommendations for the CARE Task Force &
Air District Staff– Broad representation
• Business groups• Community members• Governmental agencies – health & planning departments• Non-profit, non-governmental agencies• Air District Staff
Cumulative Impacts Resolution
December 4, 2008 18
CARE Mitigation Action Plan has focused on reducing diesel PM, especially in the six impacted communities.
What additional actions within these communities?
Other areas where the Air District should focus?– Compare benefit of additional actions to benefits of
diesel PM reductions
What actions should be taken by other agencies or groups?
How can we improve collaboration between various agencies and groups?
