7 Key Themes for EPA Lisa P. Jackson, EPA Administrator - January 12, 2010 1.Taking Action on Climate Change 2.Improving Air Quality 3.Assuring the Safety of Chemicals 4.Cleaning Up Our Communities 5.Protecting Americas Waters 6.Expanding the Conversation on Environmentalism and Working for Environmental Justice 7.Building Strong State and Tribal Partnerships
1.Taking Action on Climate Change Q: How will we (the U.S. / the developed world / the planet) deal with the biggest (in terms of scale, impact and economics) environmental challenge to date??? A: For the U.S. – It depends
The Legislative Options Enactment of new clean energy / climate legislation OR Implementation of the 1990 Clean Air Act
Legislation House –Waxman (D-CA)-Markey (D-MA) Bill (American Clean Energy and Security Act of 2009) –Approved by the House of Representatives on June 26, 2009 –Cap-and-trade Senate –Kerry (D-MA), Graham (R-SC), and Lieberman (I-CT) working outside of the committee process (through closed-door meetings) –Framework for Climate Action and Energy Independence –A combination of cap-and-trade and cap-and-dividend
1990 Clean Air Act Massachusetts v. EPA (April 2007) Endangerment Finding (December 2009) Greenhouse Gas Emission Standards for Light Duty Vehicles (April 2010) Tailoring Rule (Proposed September 2009) Johnson Memo Reconsideration (March 2010) Greenhouse Gas Reporting Rule (Published October 2009)
2. Improving Air Quality The Conventional Pollutants & Programs (some with a new twist) – National Ambient Air Quality Standards – Air Toxics – Clean Air Interstate Rule (CAIR) – New Source Review (NSR) & Prevention of Significant Deterioration (PSD) – Enforcement
National Ambient Air Quality Standard Actions in 2010 NO 2 – Final in January 2010 SO 2 – Final in June 2010 O 3 Reconsideration – Final in August 2010 CO – Proposal in October 2010 PM – Proposal in November 2010
5. Protecting Americas Waters Air-Water Interface – Northeast States' 319(g) Petition on Mercury Deposition – Nitrogen deposition Water-Air Interface – A lot of air pollution is generated to pump, treat and heat water or waste Solid Waste-Air Interface – Using recycled or re-used materials reduces emissions from: the extraction of raw materials the manufacture of goods methane (GHG) emissions from landfills
6. … Environmental Justice Focus on communities historically under- represented in EPA decision making – Tribes, communities of color, economically distressed areas – Children Develop guidelines for including environ- mental justice principles in decisions
7. Building Strong State … Partnerships View states as co-regulators Provide as much support as possible – financial and technical

Ozone NAAQS Reconsideration Proposal signed on January 6, 2010. Public comment period of 60 days closes on March 22, 2010 3 Public hearings Final Rule to be signed by August 31, 2010.
Daily value = Sum of values over 12 daylight hours Steps in calculating W126 value for a particular site: 1.Measure hourly ozone (O 3 ) concentrations for each hour within the 12 hour daylight period (8am-8pm). 2.Assign a weight to each hourly value based on concentration: lower concentrations receive less weight than higher concentrations. 3.Sum the 12 weighted hourly values to calculate a daily W126 value. 4.Repeat steps 1-3 for each day within the ozone season and then sum the daily values to calculate the monthly W126 value. 5.Identify the consecutive 3-month period whose monthly W126 values produce the highest total. This total becomes the seasonal W126 for this site. 6.Average three years of maximum W126 values and compare to standard. Hourly O 3 (ppm) WeightW126 (ppm-hrs) 0.030.010.00 0.050.110.01 0.060.300.02 0.080.840.07 0.101.00.10 SUM:0.20 weight Understanding the W126 Proposed Secondary Standard Example of weighting over 5-hour period:

CO NAAQS Proposal Oct 28, 2010 Final May 13, 2011 March 22-23 CASAC review of the 2 nd draft Risk and Exposure Assessment and draft Policy Assessment
Remand of Primary and Secondary Annual PM 2.5 Standard In Feb 2009, D.C. Circuit Court remanded some portions of the final rule Court concluded EPA failed to adequately explain why annual standard is sufficient to protect public health with an adequate margin of safety Annual primary standard remanded for further consideration of whether it provides an adequate margin of safety from the risk of short-term exposure to PM 2.5, and whether it provides an adequate margin of safety against morbidity in children and other vulnerable subpopulations Court concluded decision to set secondary standards identical to primary standards was unreasonable and contrary to the law Secondary standards remanded for reconsideration
PM NAAQS Review Integrated Science Assessment –Finalized December 2009 Risk and Exposure Assessments –Second draft assessment documents (quantitative health risk assessment and urban-focused visibility assessment) released for CASAC and public review on March 10-11 Policy Assessment –First draft released for CASAC and public review in March 2010 –Will discuss CASAC comments at teleconference scheduled for April 8 Proposed rulemaking – November 2010 Final rulemaking – July 2011 For more information: http://www.epa.gov/ttn/naaqs/standards/pm/s_pm_index.html
