Reducing Diesel Emissions in Arizona Laura Moreno U.S. Environmental Protection Agency Region 9 March 7, 2009
Overview • Why should we care about diesel air pollution? • What is the U.S. Environmental Protection Agency doing about it? • What can we do to help reduce air pollution and greenhouse gases?
Components of Diesel Emissions • Nitrous Oxide (NOx) • Contributes to ozone creation • Greenhouse gas • Particulate Matter (PM) • Driver of Risk Hair cross section (70 mm) Human Hair (70 µm diameter) PM10 (10µm) PM2.5 (2.5 µm)
Diesel emissions pose a significant environmental health problem • Serious health impacts • Asthma, respiratory & cardiac illness • Possible human carcinogen • Impacts air quality • Contributes to climate change Paul Bubbosh (EPA OTAQ), Deborah Jordan (EPA R9), and Michael Antonovich (LA County Supervisor and AQMD Board Member) announce a Smartway project to reduce diesel emissions with children from Horace Mann elementary school in Los Angeles on September 30, 2004.
Some Groups Are More at Risk • People with heart or lung disease • Conditions make them vulnerable • Older adults • Greater prevalence of heart and lung disease • Children • More likely to be active • Bodies still developing • Breathe more per body pound
Mobile Diesel Emission Sources by Sector FREIGHT 32% FREIGHT 56% Source: Mobile Source Diesel Emissions Inventory by Sector (2004)
PM and Ozone Pollution in Arizona • Sources: • Dust • Diesel • Wood Smoke • Industrial sources (mining, etc.) Source: Arizona Department of Environmental Quality
What is the U.S. Environmental Protection Agency and its Partners doing to reduce air pollution and greenhouse gases? • Rules and regulations • Voluntary programs • Grant projects • Education
What is the West Coast Collaborative? • Public-private partnership • Aims to reduce diesel emissions in the most impacted communities by: • Creating information sharing along major transportation corridors in the West • Leveraging new resources • Developing and implementing projects • Goals: • Protect & Improve Public Health • Support Energy Security & Greenhouse Gas Reductions
Projects in Arizona/Sonora • Reducing Truck Idling at the Border • Construct 3 truck stop electrification sites where truckers turn off their engine and plug-in to use electricity • Reduce idling by 20% • Improve air quality for communities along the Border
Projects in Arizona/Sonora • Retrofitting Trucks & School Buses in Nogales • 55 heavy duty trucks retrofits to capture air pollution • 32 school bus retrofits for the Rio Rico School District • Reduce air pollution by 30%
Biodiesel: Fat to Fuel Alternative fuel from new or used oil Can be blended with traditional fuel (e.g. B20) Benefits: Reduce particulate matter (PM), sulfur dioxide, and carbon dioxide emissions Divert waste from landfill/wastewater system Improve water quality Renewable source of energy Non-toxic Provides energy security
Biodiesel: Fat to Fuel Why Use Waste Cooking Oil? Hotels and restaurants in the U.S. generate 3 billion gallons of waste cooking oil per year 80% of sanitary sewage overflow events in the US are caused by fats, oils, and grease San Francisco 3 billion gallons = 5,700 miles of tanker trucks end-to-end New York
Biodiesel in Arizona Deer Valley School District (1999) Switched fleet (250 vehicles) and maintenance trucks (5) to B100 Switched school buses (140 vehicles) to B20 Increased performance of school buses Used and virgin biodiesel
Biodiesel in Arizona Ambos Nogales Improper disposal of waste vegetable oil and grease causing sewer clogs and overflows Frequent non-attainment for particulate matter Reclaim waste oil and grease from local restaurants and maquiladores Use biodiesel in school buses, fire trucks, and other city vehicles
Partnership Programs • Break down market barriers impeding deployment of cost-effective technologies and practices that reduce environmental impact • Facilitate environmental performance where there is no regulation
SmartWay • Promotes smart transportation choices when purchasing vehicles and trucks • Helps save fuel, $, and your impact on the environment • Vehicles that qualify for the SmartWay mark are the cleanest and most fuel-efficient
SmartWay • Contains a comprehensive listing for all vehicles • Vehicles receive two environmental scores • Greenhouse Gas Score • Air Pollution Score
SmartWay • Scored on a scale of 1-10 (10 = best) • Best environmental performers receive a SmartWay Certified/Elite designation • Go to EPA’s Green Vehicle Guide website and click on the SmartWay box • www.epa.gov/greenvehicles
