Improving Air Quality for Health: Analysis Options

This report provides background information on the health impacts of air pollution and steps for conducting Health Benefits Assessment. An applied example focusing on Chesapeake Bay TMDLs is included, along with analysis options for evaluating PM impacts. The document outlines screening-level and EPA RIA-style analyses for Control and HAPs. It also presents results and monetary benefits for reductions in PM2.5, specifically in the woodstove analysis setup for 2025. Various scenarios and emission factors are considered, emphasizing the need for thorough assessment methodologies.

Presentation Transcript

  1. Health Benefits of Improvements in Air Quality: Background and Analysis Options Prepared for Northwest Power and Conservation Council by Abt Associates Inc. August 2013

  2. Contents • Background • Health impacts of air pollution • Steps of Health Benefits Assessment (HBA) • Applied example: Impacts of Chesapeake Bay TMDLs • Analysis options • Screening-level analysis of PM impacts • EPA RIA-style analysis for CAPs • EPA RIA-style analysis for CAPs and HAPs

  3. Health Impacts of Air Pollution Source: Partiallyadapted fromWHO 2005 Severity Affected Population

  4. Steps of HBA

  5. Chesapeake Study Setting

  6. Chesapeake Results for 2025 Reductions in PM2.5 Monetary benefits

  7. RTF Woodstove Analysis Setup • One model year • Two region-specific scenarios: • Baseline: Some winter heat is generated by burning wood; • Control: No winter heat is generated by burning wood, but there is a compensating increase in electricity use • Emissions of SOx, VOC, PM2.5, PM10, NOx, HAPS may be affected. All options will: • Use EPA's Residential Wood Combustion Tool to estimate wood burning emissions baseline (at county- or grid-level, depending on the option). • Require development and implementation of an approach to model commensurate changes in EGU emissions

  8. Screening-Level Analysis

  9. EPA RIA-style analysis for CAPs

  10. EPA RIA-style analysis for CAPs & HAPs
