f£\ CLEANUP - CLEAN AIR USElj DIESEL EMISSIONS & GREENHOUSE GAS REDUCTIONS Clean Diesel Technologies & Alternative Fuels at Brownfields Cleanup & Redevelopment Sites How can Brownfields Reduce Diesel Pollution? RETROFIT engines with emission control technologies MAINTAIN in accordance with engine manual (i.e., change air filters, check engine timing, fuel injectors and pumps) REFUEL with biodiesel, other alternative fuels, or with cleaner fuels such as ultra-low-sulfur diesel (ULSD) MODIFY OPERATIONS by reducing operating and idle time REPLACE existing engines with new cleaner diesel engines, hybrid engines, or engines compatible with alternative fuels Calculate Emissions Reductions The Quantifier http://cfpub.epa.gov/quantifier/ Why Use Clean Diesel Equipment? • Exposure to diesel emissions such as particulate matter (PM) can have serious health effects, e.g. asthma attacks, heart attacks. • Diesel exhaust is a "likely human carcinogen." • Exposure to diesel emissions is of concern for site workers and surrounding communities. • Diesel engines emit hydrocarbons (HC) and nitrogen oxides (N0X) which contribute to smog, and carbon monoxide (CO), a poisonous gas. What are Some Retrofit Options? The most common options are Diesel Particulate Filters (DPFs) and Diesel Oxidation Catalysts (DOCs), both of which fit on engines like Retrofit Device Reductions Cost per retrofit DPF PM 90% HC 90% CO 60-90% $7,000-$10,000 DOC PM 20-50% HC 50% CO 40% $500-$2,000 What are Some Alternative Fuel Options? Alternative Fuel Reductions Cost per gallon vs. diesel B20 Biodiesel* PM 10% CO 11% HC 20% C02 15% 200 less - 400 more Emulsified Fuel PM 16-58% NOx 9-20% CO 13% ~ 200 more Natural Gas PM 99% NOx 25-60% CO 90-97% HC 50-75% COz 25% ~$1 less *Blend of 20% biodiesel, 80% diesef Further research is needed but some studies have shown slight increases in NOx emissions compared to diesei.

GENERATE renewable energy on-site CONSERVE energy by using energy efficient equipment and lighting and reducing energy use DESIGN GREEN BUILDINGS to dramatically reduce energy consumption and costs Calculate Emissions Reductions www.cleanerandqreener.org/resources/ emission rednctions.htm What are Renewable Energy Sources? These sources naturally regenerate energy at the same or greater rate than the energy being consumed. While fossil fuels are being depleted, renewable energy technologies provide a lasting source of energy. They include solar, wind, biomass, hydro, and geothermal sources. Energy from these sources can be used directly or converted into electricity. Why Use Renewable Energy Technologies? • Environmental cleanup systems can operate for years to decades. For longer-term cleanup systems, like groundwater pump-and-treat systems, renewable energy technologies, such as solar panels, can be used to augment the power supply. • Choose renewable energy technologies for residential or commercial redevelopment projects to generate electricity on- site. • Using renewable energy technologies reduces pollution and greenhouse gases from the burning of limited fossil fuels. • Reduce dependence on foreign resources. What are Some Renewable Energy Technologies? Soiar panels on rooftops can provide a large amount of energy for a home or business and may make the electric meter run backwards; Cost: $7-$12 per watt before rebates Wind turbines harness wind energy. A single medium sized wind turbine with good wind conditions can provide enough energy for eight 3-bedroom homes; Cost: $2,000-$7,000 per kW (source: www.windfarmersnetwork.org) Biomass energy can come from plants or animal manure. Electricity can be generated from methane gas that is produced as the biomass decomposes; Cost: ~ $4,000 per kW (source: www.epa.gov/aastar) Funding Resources Federal, State, and Local tax credits and rebates are available for energy efficient buildings and/or installation of renewable energy technologies, www.dsireusa.org For general information visit: Cleanup - Clean Air website: For more information contact: www, epa. gov/cleanenergy * www.nrel.gov * www.eere.enerev. gov www.epa.gov/region9/cleamip-clean-air Jennifer Wang Wang.
