Using the Clean Air Act to Sharply Reduce Carbon Pollution from Existing Power Plants, Delivering Health, Environmental and Economic Benefits
March 2014 Update
SMART WAYS THE CLEAN AIR ACT CAN CLEAN UP AMERICA’S
BIGGEST CLIMATE POLLUTERS
“We limit the amount of toxic chemicals like mercury and sulfur and arsenic in our air or our water, but power plants can still dump unlimited amounts of carbon pollution into the air for free. That’s not right, that’s not safe, and it needs to stop.”
-President Obama, June 25th, 2013
January 20th Start of President Obama\'s second term.
June 25th President Obama announces Climate Action Plan.
September 20th EPA proposes carbon pollution standards for future power plants.
May 9th End of public comment period for future power plant proposal.
June 1st EPA to propose guideline for carbon pollution standards for existing
June-September Public comment period on existing power plant proposal.
June 1st EPA to finalize power plant carbon pollution standards.
June 30th States to submit implementation plans for existing
power plants to EPA.
July-December EPA reviews state plans for compliance with its guideline.
January 20th End of President Obama\'s second term.
THE “101” ON 111 (d)
EPA CO2 Emissions Guideline & State Plans
“Best System of Emission Reduction”
SYSTEM-BASED, STATE SPECIFIC STANDARDS
State-specific fossil-fleet average CO2 emission rates (lbs/MWh) for 2020 and 2025
Calculatedby applying benchmark coal and gas rates to each state’s baseline (2008-2010) fossil generation mix
Averagingallowed among all fossil units in state (including new units subject to the 111(b) standard)
Credit for incremental renewables and energy efficiency (equivalent to adding MWhs to denominator in calculating emission rate for compliance purposes)
States may opt in to interstate averaging or credit trading
States may adoptalternative plans, including mass-based standards, provided they achieve equivalent emission reductions

A multi-statecompliance agreement would allow each state to plan around utility portfolios, whether or not they cross state lines
HIGHER AND LOWER COST OPTIONS TO REACH THE SAME EMISSIONS LEVELS: NORTHWEST EXAMPLE
The Northwest Power and Conservation Council analyze three pathways to ~35% emissions reductions by 2029 for the region, including imported power
All scenariosincluded 5900 MW of additional Energy Efficiency
