# Clean Air Act Section 111 and the

President’s Directive Develop carbon pollution standards, regulations or guidelines, as appropriate, for: 1. New power plants  Proposed: January 8, 2014 

## 2. Modified and reconstructed power plants
 Proposal: June 2014  Final: June 2015 

## 3. Existing power plants
 Proposed Guidelines: June 2, 2014  Final Guidelines: June 1, 2015  State Plans due: June 2016

# Best System of Emissions Reductions Building Block Strategy EPA Used to Calculate the State Goal Maximum Flexibility: Examples of State Compliance Measures 1. Make fossil fuel -fired power plants more efficient Efficiency Improvements Efficiency improvements Co-firing or switching to natural gas Coal retirements Retrofit CCS 2. Use lower- emitting power sources more Dispatch changes to existing natural gas combined cycle (CC) Dispatch changes to existing natural gas CC 3. Build more zero/lowemitting energy sources Renewable Energy Certain Nuclear New NGCC Renewables Nuclear (new and up - rates) New coal with CCS 4. Use electricity more efficiently Demand -side energy efficiency programs Demand -side energy efficiency programs Transmission efficiency improvements Energy storage 5

# Flexibilities Available To States

 Timing:  Up to 15 -year window in which to plan for and achieve reductions in carbon pollution.  U p to two or three years to submit final plans.  Form of goal: States can use either a rate - based or mass based goal.  Single or multi -state plans: States can collaborate and develop plans on a multi -state basis.  Selection of measures :  States will choose how to meet the goal through whatever collection of measures reflects its particular circumstances and policy objectives.  State measures may impact and, in fact may be explicitly designed to reduce, CO 2 emissions from utilities on a regional basis.  EPA would support building off existing reduction programs.

# Costs and Benefits of the

Proposed Plan

 Estimated Costs of the plan are $7.3 billion to $8.8 billion in 2030.  Benefits by 2030  

### CO 2 

### emissions from the power sector reduced by approximately 30% from 2005 levels.  

### Pollutants that contribute to the soot and smog reduced by over 25%  

### Avoid an estimated 2,700 to 6,600 premature deaths  

### Avoid 140,000 to 150,000 asthma attacks  

### These reductions will lead to public health and climate benefits worth an estimated $55 billion to $93 billion in 2030.  Health and climate benefits far outweigh the estimated annual costs 

### of meeting the standards.

# Comment Period

 EPA held 4 public hearings last week in Denver , Atlanta , Pittsburgh and Washington, D.C.

 There is a 120 - day public comment period on the proposal, closing October 16, 2014.
