  1. NAAQS SIPs Requirementsand Regional Haze FUGITIVE DUST CONFERENCE May 10, 2005 California Environmental Protection Agency Air Resources Board

  2. OVERVIEW • Pollutants of Concern • health standards and goals (NAAQS) National Ambient Air Quality Standards • PM, Dust, and Regional Haze • what monitoring indicates • The SIP Process • coordinated approach for reducing pollutants

  3. Ozone (ROG + NOx) Particles (PM10/PM2.5) One Atmosphere - Many Pollutants Haze nitrates, sulfates, carbon compounds, coarse mass, fine dust Greenhouse Gases CFCs, CO2, CH3, NOx, O3 Toxics benzene diesel particles PAHs PCBs asbestos nitrates, sulfates, crustal matter, fine dust, carbon compounds Acid Rain (SOx , NOx)

  4. Key Criteria Pollutants Particulate Matter (PM10/PM2.5) Ozone Pollutants: Atmospheric Reactions: Organic Gases (ROG) Ammonia (NH3) Nitrogen Oxides (NOx) Particles (dust soot droplets) Sulfur Oxides (SOx) Emissions: Typical Sources: solvents fuel combustion livestock waste pesticides plants fuel combustion livestock waste fertilizers composting soil & debris process loss stockpiles roads burning fuel shipping refining diesel fuel

  5. Federal & California Ambient Air Quality Standards First Reasonable Progress Goal for Regional Haze….2018

  6. NAAQS Non-Attainment Areas Ozone 1-hr & 8-hr PM10 Class 1 areas & PM non-attainment PM2.5 PM2.5 & Ozone 8-hr

  7. California’s Challenge Lake Sacramento  San Francisco  Los Angeles 34 million people Federal & State non-attainment 29 class 1 areas

  8. Regional Haze in California Current visibility (deciviews) • southern worse than northern • worst days throughout year • causes different each month Pollutants in worst months • ammonium nitrate (southern) • ammonium sulfate (coastal) • organic carbon (northern, including Sierra Nevada) Coarse matter, fine soil • less than 20% of annual light extinction • coarse mass consistently higher concentration than fine soil • generally less than 10% of light extinction on worst days

  9. Average Fine and Coarse PM Summer 1996-1999 Winter 1996-1999

  10. PM Levels Vary: Season & Location

  11. Visibility at Joshua Tree

  12. State Implementation Plan Clean Air SIP Assess Controls Modeling Emission Inventory Air Quality Monitoring

  13. SIP Planning Milestones Baseline emissions inventory………….Spring ’05 Forecasting and modeling ……………..Summer ’05 Finalize emission targets ………………Summer ’06 Local/State/federal control concepts …Summer ‘06 Draft plans & workshops………………..Fall ’06 Local & state plan adoption…………….Spring ’07 • Ozone plans due to U.S. EPA June ’07 • Regional Haze plans due to U.S. EPA December ’07 • PM2.5 plans due to U.S. EPA April ’08

  14. California’s Strategy to Address PM Pollution • Continue NOx and ROG control strategy for both ozone and secondary PM • Federal: fuels, offshore shipping • State: mobile sources, fuels, consumer products • Local: point sources, area sources • Emission reduction strategies for primary PM from combustion • Diesel PM Risk Reduction Plan • Smoke Management Program • Agricultural Burning (SB 705) and Residential Controls (ATCM) • Address local PM problems with all feasible measures • BACM (required for NAAQS non-attainment) • SB 656 (required for State PM standards) • SB 700 (agriculture emissions, including ammonia) • Voluntary Measures & Incentive Programs • Don’t Light Tonight, EQUIP, CMPs, Moyer Program

  15. Establish requirements for: Construction and demolition Paved and unpaved roadways Vacant or fallow land Agricultural operations Mining activities Stockpiling and transfers Typical strategies include watering, applying dust suppressants, paving, setting speed limits, establishing vegetation Local Dust Control Measures
