Community Air Risk Evaluation (CARE) Program

Contra Costa County

Forum on

Cumulative Impacts of Pollution

Philip Martien, Ph.D.

Bay Area Air Quality Management District

December 4, 2008


Overview
Overview

  • Community Air Risk Evaluation (CARE) Program

  • CARE Mitigation Action Plan

  • Multi-pollutant Clean Air Plan

  • Cumulative Impacts Resolution


Regulatory authority
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
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


From emissions of toxic air contaminants to health effects

Model estimated cancer risk
Model Estimated Cancer Risk*

Expected cancer incidents per million people

Modeled concentrations weighted by health risk of each compound

Based on year 2005 emissions

*Cancer risk from:

Diesel PM

Benzene

1-3, butadiene

Formaldehyde

Acetaldehyde

Measured trends in toxic air contaminants show risk reduction
Measured Trends in Toxic Air Contaminants Show Risk Reduction

  • 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

Demographic health data

Care mitigation action plan
CARE Mitigation Action Plan Reduction

  • 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



Community outreach

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

13


Land use guidance
Land Use Guidance on projects to fund

  • 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


Land use issues
Land Use Issues on projects to fund

  • 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


2009 clean air plan
2009 Clean Air Plan on projects to fund

  • 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


Cumulative Impacts Resolution on projects to fund

  • 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


Key Questions for Working Group on projects to fund

  • 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?
