Approach for Supplemental Proposal

► BSER and setting goals:

► Proposing that BSER is the same as for states► Proposing same methodology as for states to determine goals; ap

building blocks to 2012 data

• Note that for building block 3 there are no renewable energy (RE) 

Indian country and territories using the method proposed for statenon-hydropower RE generation for those areas is zero

• We are taking comment on an adjustment to the proposed metho

results in a positive amount of RE for building block 3

► For Indian country, proposing goals for each of the three are

country with affected EGUs: lands of the Navajo Nation, Ute Uintah and Ouray Reservation, and Fort Mojave Tribe

► For territories, proposing goals for Puerto Rico and Guam o

► No affected EGUs identified in American Samoa or Northern Maria► Two potentially affected EGUs in U.S. Virgin Islands; one has not 

years and the other has not operated since 2011; therefore, their 2has no affected units and we are not proposing a goal

Implementation Plan Guidelines for Indian Country an

► Areas of Indian country with affected EGUs:

► Tribes can choose to seek the authority to develop a plan, but 

required to do so

► Pursuant to Tribal Authority Rule, EPA must promulgate such f

provisions as are necessary or appropriate if a tribe does not sthe authority to submit a plan

► We are not proposing a determination regarding any tribe’s elig

develop a plan or whether a federal plan is necessary or appro

► Territories:

► Proposing the same guidelines and timing for implementation 

proposed for states 

► Areas without affected EGUs (e.g., other tribal areas, Vermo

Canada):

include EE, RE and new units located in areas without affected

Impacts of Supplemental Proposal

► Indian country: no additional costs, emission reductions or ben

► Navajo: if converted to mass-based goal, expected to comply w

additional actions beyond shutdowns already occurring due to 

► Ute: costs, reductions and benefits already included in June pr

• Plant not identified as affected but was given opportunity to im

in the modeling, which projected a heat rate improvement; thualready captured the impact of the goal on this plant

► Fort Mojave: no costs, reductions or benefits since goal is equ

baseline

► Territories:

► Costs in 2030: savings of $410 million► CO2 reductions in 2030: 3.4 million tons ► Climate benefits in 2030: $190 million (2011$ at a 3% discount ► We are unable to estimate the criteria pollutant reductions in th

to data limitations 

► Additionally, we would be unable to quantify health co-benefits 

because the benefit-per-ton values used are only appropriate fthe continental U.S.; we discuss the potential health impacts oqualitatively
