Green Remediation: Opening the Door to Field Use Session B (Green Remediation Tools and Examples) December 16, 2008 Carlos Pachon U.S. EPA Superfund Program pachon.carlos@epa.gov
What is Green Remediation? The practice of considering all environmental effects of a cleanup during each phase of the process, and incorporating strategies to maximize net environmental benefit of the cleanup. Focus is on remedy implementation vs. remedy selection
Is it Our Job? • Executive Order 13423, January 26, 2007-Strengthening Federal Environmental, Energy, and Transportation Management • Section 1. Policy. It is the policy of the United States that Federal agencies conduct their environmental, transportation, and energy-related activities under the law in support of their respective missions in an environmentally, economically and fiscally sound, integrated, continuously improving, efficient, and sustainable manner. • EPA Strategic Plan Goal 1: Clean Air and Global Climate Change • Protect and improve the air so it is healthy to breathe and risks to human health and the environment are reduced. Reduce greenhouse gas intensity by enhancing partnerships with businesses and other sectors. • EPA Strategic Plan Goal 5: Compliance and Environmental Stewardship • Stewards of the environment recycle wastes to the greatest extent possible, minimize or eliminate pollution at its source, conserve natural resources, and use energy efficiently to prevent harm to the environment or human health.
Opportunities to Increase Sustainability in Site Cleanups Apply to all cleanup programs Exist throughout site investigation, design, construction, operation, and monitoring Are aligned with our mandates (EPA Strategy, EO13423, etc).
Core Elements: Energy Requirements Energy efficient equipment operating at peak performance Periodic evaluation and optimization of equipment with high energy demand Renewable energy systems to replace or offset grid electricity Managed demand to leverage low peak capacity and rates

Why Transportation? • Transportation is often the biggest energy consumer for site cleanups. • Transportation and other vehicles used can be the biggest polluters for each unit of energy required to do the cleanup at your site, increasing short term risks.
West Coast Collaborative Goals • Protect/Improve Public Health by: • Helping to meet National Ambient Air Quality Standards (PM2.5, Ozone) • Meeting air toxics goals (both federal and state/local partners) • Support Energy Security and Green House Gas Reductions by: • Using cleaner fuels (biodiesel, biogas/natural gas, electric …) relative to total diesel fuel • Advance regional/local production of renewable fuels supporting local agriculture and forestry sectors • Utilize SmartWay and other programs to virtually eliminate on-road, locomotive, and non-road HDD idling (ports, corridors, distribution locations)
Why is Reducing Emissions Important? Degrades Air Quality • Particulate Matter (PM) • Ozone precursors Energy and Climate Change • Over 40% of green house gas emissions from mobile sources • Over 90% of fuel imported petroleum Serious Health Effects • Diesel exhaust is a “likely human carcinogen” and respiratory irritant • Harmful diesel PM • Diesel exhaust contains “likely” and “known” (e.g., benzene) human carcinogens, and also have respiratory, neurological, developmental, and immunological health effects.
Particulate Matter (PM) In Diesel Exhaust Is The Driver Of Risk • Mix of particles and liquid droplets • Considerably smaller in size than human hair • Penetrates deeply into the lungs Hair cross section (70 mm) PM10 (10µm) PM2.5 (2.5 µm) Human Hair (70 µm diameter)
Avoiding Or Substantially Reducing Emissions • Switch from truck to rail transport • Investigate on-site disposal options • Integrate diesel emissions into short term impact analyses to allow for lower impact technology to be identified during FS analysis
What If Rail Transport Isn’t Practical? What Now? • Diesel emissions controls may be a viable and cost effective option at your site.
Diesel Oxidation Catalyst • Emissions Reductions • 20% - 50% reduction in PM • 60% - 90% reduction in HC • >90% reduction in CO
Diesel Particulate Filter Trapped PM Exhaust (CO2, H2O)Out Exhaust(PM, CO, HC)Enter • Emissions Reductions • 95% PM reduction • 90% HC reduction • 90% CO reduction Ceramic HoneycombWall
Diesel Particulate Filter Emissions Reductions 29 Typical test filter – no DPF Test filter – with DPF Unused test filter
30 Diesel Multistage Filter (DMFs)
Other Emissions Control Technologies & Cleaner Fuels • Selective Catalytic Reduction (SCRs) • 20% - 50% reduction in PM • 60% - 90% reduction in HC • >90% reduction in CO • 25% - 50% reduction in NOx • Biodiesel – Neet or blends (~$5/gallon - virgin biodiesel) • 10% to 50 % reduction in PM • Ultra Low Sulfur Diesel (ULSD)
