CLEAN POWER PLANReducing Carbon Pollution FromExisting Power PlantsProposal Announced onJune 2, 2014This Proposal Deals With the LargestSource of GHG Emissions in the U.S.2Outline•Summary of Proposal•Background on Clean Air Act Section 111(d)•Pre-proposal Outreach & What We Heard•Setting State Goals•State Plans for Meeting Goals•Costs and Benefits•Next Steps3This proposal will:•Reduce carbon pollution from existing power plants,for which there arecurrently no national limits.•Maintain an affordable, reliable energy system.•By 2030, reduce nationwide carbon dioxide (CO2) emissions, from the powersector by approximately 30% from 2005 levels.•Significant reductions begin by 2020.•Cut hundreds of thousands of tons of harmful particle pollution, sulfurdioxide and nitrogen oxides as a co-benefit.•Provide important health protections to the most vulnerable, such aschildren and older Americans.•Lead to health and climate benefits worth an estimated $55 billion to $93billion in 2030.•From soot and smog reductions alone, for every dollar invested through theClean Power Plan – American families will see up to$7 in health benefits.4Summary•Build on actions states, cities and businesses acrossthe country arealready taking to address the risks of climate change.•Spur investment in cleaner and more efficient technologies, creating jobsand driving innovation.•Require a reasonable emission reduction glidepath starting in 2020.•Provide a flexible timeline—up to 15 years from guideline issuance—forall emission reduction measures to be fully implemented in 2030.•Recognizing that investments in infrastructure can take time to put inplace and•Avoiding stranded assets.•Provide an array of tools states can use to formulate approvable plans.Summary (Cont’d)5Carbon Pollution and Health•Public health risks include:•Increase in heat stroke and heat-related deaths•Extreme heat events are the leading weather-relatedcause of death in the U.S.•Worsening smog (also called ground-level ozone pollution) and, in somecases, particle pollution•Increasing intensity of extreme events, like hurricanes, extremeprecipitation and flooding•Increasing the range of insects that spread diseases such as Lyme diseaseand West Nile virus.6Actions to Reduce Carbon Pollution•Building a 21stcenturytransportation sector•Cutting energy waste in homes,businesses, and factories•Reducing methane and HFCs•Preparing the U.S. for the impactsof climate change•Leading international efforts toaddress global climate change•Reducing carbon pollution frompower plants7Reducing Carbon Pollution From Power PlantsPresident’s Directive to EPA:Develop carbon pollution standards, regulations orguidelines, as appropriate, for:1. New power plants•Proposed: January 8, 20142. Modified and reconstructed power plants•Proposal: June 2014•Final: June 20153. Existing power plants•Proposed Guidelines: June 2014•Final Guidelines: June 2015•State Plans due: June 20168Background: Clean Air Act Section 111(d)Best System of Emission Reduction9•Previous EPA rules under this section of the Clean Air Act haveconsidered “add-on” control technologies – like scrubbers -- that aretechnically feasible to deploy at virtually any facility.•In contrast, there are a wide variety of ways to reduce carbon pollutionthat are commercially available, technically feasible, and cost effective.•The opportunities vary from state to state, depending on how electricityis generated, energy infrastructure, and other factors.•In this proposal, EPA took an approach that viewed the Clean Air Actfactors in determining Best System of Emission Reduction in light of theinterconnected nature of power generation.•BSER factors•Costs•Size of reductions•Technology•Feasibility•EPA conducted a robust pre-proposal stakeholderengagement process.•Participated in meetings with over 300 utility,consumer, labor and environmental groups sinceJune 2013.•Held 11 public listening sessions around thecountry.•3,300 people attended.•More than 1,600 people offered oralstatements.•Reached out to all 50 states.•Some states noted their programs to addresscarbon evolved because of:•The need to address carbon pollution;•Electric system that is dynamic, and in themidst of market changes; and•Modernizing the power sector is good for theeconomy.•Common themes included reliability, flexibility,affordability, time for plans and implementation.10Early Outreach Informed This ProposalStates and Communities withPrograms That Reduce Carbon PollutionState programs that reduce carbon includecarbon cap and trade programs and energyefficiency and renewable energy standards orgoals.11EPA Sets the Goals12EPA Establishes a Goal for Every State•EPA analyzed the practical and affordable strategies that states and utilities arealready using to lower carbon pollution from the power sector.•Proposed goals are based on a consistent national formula, calculated with stateand regional specific information.•The result of the equation is the state goal.•Each state goal is a rate – a statewide number for the future carbon intensity ofcovered existing fossil-fuel-fired power plants ina state.•Encompasses the dynamic variables that ultimately determine how much carbon pollution isemitted by fossil fuel power plants.•Accommodates the fact that CO2emissions from fossil fuel-fired power plants are influencedby how efficiently they operate and by how much they operate.•The state goal rate is calculated to account for the mix of power sources in eachstate and the application of the “building blocks”that make up the best system ofemission reduction.•States will need to meet an interim goal and a final goal.13States Have FlexibilityBasis for state goal–Potential emissionspathway reflectingEPA’s analysis2020 2021 20222023 2024 20252026 2027 2028 2029A state can choose any trajectoryof emission improvement as longas the interim performance goal ismet on average over 10 years, andthe final goal is met by 203014
