Clean Power Plan Proposals

► June 2014: EPA issued the Clean Power Plan pr

address carbon pollution from affected power plaincluding:

► State-specific goals for reducing CO

2 emissions fro

power plants

► Guidelines for state plans to achieve the state-spe► Affected power plants located in Indian country wo

encompassed within a state’s plan

► Comment period closed December 1, 2014

► October 2014: EPA issued the Clean Power Plan 

supplemental proposal to address carbon polluaffected power plants in Indian country and U.S. t

► Comment period closed December 19, 2014
Why is EPA Proposing the Clean Power Plan

► CO

2 is a potent greenhouse gas (GHG) that contr

climate change 

► CO

2 is the primary GHG pollutant, accounting for 

75% of global GHG emissions and 82% of GHG eacross the country

► GHG pollution is causing potentially rapid, damag

long-lasting changes in our climate that can have severe negative effects on human health and the environment
General Overview of Clean Power Plan

► EPA proposed an interim (2020-2029) and final C

reduction goal (2030) for affected power plants in 

► EPA is not prescribing specific measures to meet ► Areas have flexibility to choose what goes into th

how and when to get the necessary reductions, pgoals are met in established timeframe

► Choose what works best in an area, tailored to its needs and 

objectives

► Option to translate how an area measures their goal► Opportunity to build on existing energy efficiency and renewa

programs 

► Option to work with other areas through multi-jurisdictional pla► Fits into existing utility electricity sector planning processes
Goals for Emission Reduction

► Because the power sector is interconnected, EPA pro

a set of 4 types of measures, or “building blocks,” togethe best system to reduce carbon pollution from fossil power plants

► 4 Building Blocks: 

(1) Improve coal plants efficiency (e.g., heat rate improvements)(2) Increase use of efficient natural gas combined (NGCC) units (3) Increase use of renewable energy and/or low cpower production (e.g., wind or solar)(4) Reduce demand for power through energy effi
Power Plants in Indian Country

► Four affected power plants:

► Four Corners Power Plant on Navajo tribal lands w

Mexico

► Navajo Generating Station on Navajo tribal lands w

Arizona

► South Point Energy Center on Fort Mojave tribal la

Arizona

► Bonanza Power Plant on Ute tribal lands within Uta

 EPA proposed interim and final goals for each are

country with affected power plants
Proposed Goal for Navajo Nation

► EPA proposed a goal for Navajo Nation that requ

reduction in the 2012 CO

2 emission rate

► EPA expects the goal for Navajo Nation may be m

any additional actions beyond the shutdowns thaalready occurred at Four Corners and are expectat Navajo Generating Station to comply with Reg
Implementation Plan Guidelines

► Areas of Indian country with affected power plants

► Tribes may seek authority to implement section 111(d) p

have the ability to regulate the affected power plants

► Tribal Authority Rule says if tribes do not seek and obtai

authority to establish a plan AND EPA determines it is neappropriate, EPA must promulgate a federal plan for the 

► EPA has not proposed a determination regarding any trib

to develop a plan or whether a federal plan is necessary appropriate

► Participation of tribes without affected power plants 

► EPA took comment on allowing state or multi-jurisdiction

include energy efficiency, renewable energy, and new unareas, including Indian Country, without affected power p
Tribal Outreach and Consultation

► EPA sent consultation letters to leaders of all federally 

tribes when we issued the Clean Power Plan proposawhen we issued the supplemental proposal

► EPA held consultations on the supplemental proposal 

Tribe, Crow Nation, MHA Nation, Fort Mojave Tribe, NNation, Hopi Tribe, Ak-Chin Indian Community and FoYavapai Nation

► EPA held outreach meetings with tribes and participat

teleconferences and webinars

► EPA held a public hearing in Phoenix, Arizona on the 

supplemental proposal on November 19, 2014
Next Steps

► January 2015: 

► Begin regulatory process for proposing a federal plan to 

for cutting carbon pollution from existing power plants. Tmight be used for areas that do not submit plans

► Summer 2015:

► Final rules on proposed Clean Power Plan in State

Country and US Territories

► Carbon Pollution Standards for New, Modified and 

Reconstructed Power Plants

► Propose federal plan for public comment

► Summer 2016: 

► States submit compliance plans to EPA► EPA in a position to issue a final federal plan for areas t

submit plans

Proposed Goals for Areas of Indian Country

► Notes:

► No adjustments from building block 1 for Fort Mojave la► No adjustments from building block 2 ► Proposing one option for application of building block 3 

comment on alternatives 

► Requesting comment on projected retail electricity sales 

Indian country (used for building block 4)

Translation of Goals to Mass-Based Equival

► EPA provided additional information in November 201

potential ways to translate the rate-based CO

► First produces mass-based equivalents that apply to ex

fuel fired sources only

► Second produces mass-based equivalents that are incl
