Assessing Community Health 3

Planning Tools • Air Quality Standards / State Implementation Plans • Diesel Risk Reduction Plan • Children’s Environmental Health Act • Goods Movement Emission Reduction Plan 4

Diesel Risk Reduction Plan • Need to reduce emissions from all diesel sources • Goal is 85% reduction in emissions by 2020 Diesel PM risk Diesel PM Responsible for 70% of Year 2000 Statewide Risk from Air Toxics Emissions 5

Children’s Environmental Health Act • Special community-focused monitoring for children’s health impacts (SB 25) – Barrio Logan – Wilmington – Fruitvale (Oakland area) – Fresno – Boyle Heights – Crockett 6

Goods Movement Emission Reduction Plan • Railroad Health Risk Assessments (part of MOU) • Port of LA/Long Beach • Port of Oakland (under development) 4

Assessment Results

What have the results told us? • Diesel PM – primary source of cancer risk • Directly emitted PM and secondary PM from NOx – primary source of noncancer risk • Mobile sources predominate region impact • Other toxics play a role in near source risk 9

What are the risks? • High traffic freeways: 300 -1, 700/million 10 4

What are the risks? • Port of LA/Long Beach: 10 -500+/million 11 4

What are the risks? • Roseville Railyard: 10 -500/million 12 4

2005 Statewide Non-Cancer Health Impacts from Goods Movement Cases/Year Premature death* 2, 400 Hospital admissions (heart) 830 Hospital admissions (lung) 2, 000 Acute bronchitis 5, 100 Asthma/other respiratory 62, 000 Absences/restricted days 4. 4 million *Uncertainty range is 720 to 4, 100 deaths/year 13

Bottom Line • To improve community health we need to significantly reduce PM and NOx emissions • Reduce near source risks from toxic sources 14

Regulatory Actions

Overview of Regulatory Process Adopted ATCMs reducing: Review Sources and Control Technologies Develop Regulatory Concept Public Workshops Draft Staff Report Public Hearing Board to Adopt ATCM arsenic asbestos benzene 1, 3 butadiene cadmium diesel PM dioxins ethylene oxide formaldehyde hexavalent chromium lead methylene chloride nickel perchloroethylene trichloroethylene 16

Toxic Control Measures ATCMs reduce air toxics risks Burn Barrels from neighborhood sources…. Service Stations Dry Cleaners Automotive Repair and Refinishing Chrome Plating 17

Reducing Emissions and Risk …. and also from industrial sources Medical Waste Incinerators Metal Melting Et. O Sterilzers Asbestos in Surfacing and Construction and Mining Cooling Towers 18

Diesel PM and NOx Regulations üLow sulfur diesel fuel üTransport refrigeration units üTruck idling limits üTransit buses and refuse trucks üStationary and portable engines üAgricultural engines üInternational trucks üBan on ship incineration üShip auxiliary engine fuels üCargo handling equipment üGas forklifts 12

Rulemakings in the Works (2007 -2008) • Commercial harbor craft • Speed limits for ships • Shore power for ships • Port trucks • Privately-owned trucks • Ship main engine fuel • Cleaner ships 13

Assistance to Local Agencies

Guidance Available • Risk Assessment Guidelines • HARP • Risk Reduction Guidance – Risk Reduction Audit and Plan by Source Categories • Risk Management Guidance – Lead Risk Management – Risk Management Guidelines • Land Use Handbook 22

Wrap Up • Continue aggressive regulatory program to reduce diesel PM, NOx and toxics • Support local actions • Push federal/international standards • Work with stakeholders 23
