67408 Federal Register / Vol. 79, No. 219 / Thursday, November 13, 2014 / Proposed Rules 

2Note that the metric for compliance is 

independent from the approaches that 

implementing authorities may adopt to achieve 

them. For example, a state could potentially adopt 

a mass-based program that achieves a rate-based 

goal, or adopt rate-based standards and/or other 

measures and demonstrate that they have met the 

goal using a mass-based metric. 

3Some stakeholders have observed that 

addressing potential translation to a mass 

equivalent could incorporate generation from 

‘‘affected entities’’ that include generators beyond 

‘‘affected EGUs.’’ The proposal invited comment on 

how generation across ‘‘affected entities’’ (including 

at ‘‘affected EGUs’’) should be considered when 

calculating mass equivalents. 

4The Agency has received comments from some 

states about the accuracy of the 2012 data, as well 

as whether we should use more than a single year 

of data to determine the rate-based goals. We are 

reviewing all comments, information, and requests 

for data corrections received to date and will 

continue reviewing stakeholder input submitted to 

the docket by the close of the public comment 

period. Any changes to the emission rate-based 

goals and underlying data will be reflected in the 

final rule. 

today’s notice and accompanying TSD 

identify two sets of mass-based values 

for each state, area of Indian country 

and U.S. territory with affected EGUs 

that could be considered equivalent to 

the proposed rate-based goals, as 

discussed below: One that is based on 

historical emissions from existing 

sources, and a second that is based on 

historical emissions from existing 

sources and projected emissions that 

would result from demand growth that 

is reflected in generation at both 

existing and new sources in the event 

that an implementing authority may 

want to include new sources of 

generation in its compliance approach. 

Illustrative values for each state, area of 

Indian country and U.S. territory with 

affected EGUs (along with the 

underlying data) for each method are 

also presented in the TSD. 

In the proposed rule, the EPA 

intended to afford a considerable 

amount of flexibility in choosing the 

types of programs and measures needed 

to meet the goals established by the 

rulemaking. An important proposed 

element of this flexibility is allowing 

each implementing authority to 

demonstrate compliance with its 

interim and final rate-based goals 

established in the proposal, or to 

establish equivalent mass-based metrics 

for purposes of demonstrating 

compliance with the provisions of the 

rule. The agency recognizes that 

implementing authorities can use a mix 

of measures and programs to meet their 

goals regardless of which form of the 

standard they choose to use to 

demonstrate compliance in the state 

plan, including both programs that use 

mass-based metrics, as well as measures 

that use rate-based measures. State 

plans submitted to the EPA will be 

required either to (i) demonstrate that 

their programs and measures meet the 

rate-based goals established by the 

rulemaking, or (ii) if they choose to 

translate the rate-based goals into massbased equivalents, demonstrate 

achievement of the goals using the 

mass-based metrics.2

In section VII of the preamble to the 

June 18, 2014 proposed rule, the EPA 

provides basic considerations necessary 

to translate the emission rate-based CO2

goals into mass-based equivalents, for 

state plan purposes (79 FR 34897). The 

EPA also included in the docket for the 

rule a TSD titled ‘‘Projecting EGU CO2

Emission Performance in State Plans,’’ 

that discusses the considerations, data 

and technical approaches that can be 

considered when converting the 

emission rate-based CO2 goals into a 

mass-based equivalent metric, and 

focuses on one potential approach that 

implementing authorities could employ. 

The basic methodology presented in 

these documents is for the 

implementing authority to project for a 

given period the amount of generation 

by affected entities; to determine the 

amount of tons of CO2 that would be 

emitted by affected EGUS; and to assure 

that the ratio of affected EGU emissions 

to affected entity generation is 

equivalent to the emissions performance 

of the rate-based goal. 

The data, assumptions and 

methodological choices used for the 

estimation of generation by affected 

entities are of central importance for 

translation to a mass-based metric.3 For 

instance, uncertainties about future 

demand, the future inventory of EGUs 

and the relative amounts of generation 

among EGUs in light of, for example, 

fuel costs can influence the translation 

to a mass-based equivalent. 

In response to requests by states, we 

are issuing this notice and the TSD, 

‘‘Translation of the Clean Power Plan 

Emission Rate-Based CO2 Goals to MassBased Equivalents,’’ to present 

information about potential methods for 

translating the rate-based goals to massbased equivalents. The TSD presents 

two additional possible methods for 

calculating mass-based equivalent 

metrics, the underlying data and shows 

the mass-based equivalent metric. The 

first method, based on historical data, 

produces mass-based equivalent metrics 

that apply to existing affected EGUs 

only. The second method, based on a 

combination of historical data and a 

projection of future electric demand, 

produces mass-based equivalent metrics 

that are inclusive of new fossil fuel-fired 

sources, in light of the fact that the rule 

takes comment on the inclusion of new, 

fossil fuel-fired sources as a component 

of state plans. As the starting point for 

these calculations, we use the proposed 

emission rate-based CO2 goals set forth 

in the rulemaking. Also, to maintain 

consistency with the proposed rule, the 

calculations contain the same 

generation data used in setting the ratebased goals (i.e., 2012 eGRID data for 

historical generation, and Annual 

Energy Outlook 2013 for regional 

growth estimates) to project future 

levels of generation.4

The EPA is providing this additional 

information to states, U.S. territories, 

tribes, and other stakeholders to provide 

a better understanding of the proposed 

rule. It should be reiterated that the 

mass-based equivalent metrics 

presented in the TSD are not required 

mass-based emission limits that 

implementing authorities must meet; 

rather, they are illustrations of two 

potential options that implementing 

authorities may choose to adopt if they 

choose to use a mass-based form of the 

emission rate-based goal. The EPA 

presents them to provide stakeholders a 

better understanding of the 

methodology and mass outcomes 

associated with two possible ways of 

calculating mass-based equivalent 

metrics.

II. Background 

The 1996 Safe Drinking Water Act 

Amendments require EPA to determine 

whether to regulate at least five 

unregulated contaminants from the 

current Contaminant Candidate List 

(CCL) with national primary drinking 

water regulations every five years. The 

process of making decisions about 

whether to regulate any of the CCL 

unregulated contaminants is called 

Regulatory Determination. On October 

8, 2009 (74 FR 51850), EPA published 

the CCL3 containing 116 unregulated 

contaminants. On October 20, 2014 (79 

FR 62716), EPA announced and 

solicited public comment on its 

preliminary determinations to regulate 

one contaminant (i.e., strontium) and to 

not regulate four contaminants (i.e., 1,3- 

dinitrobenzene, dimethoate, terbufos 

and terbufos sulfone). The public 

comment period for the October 20, 

2014, FR announcement, Preliminary 

Regulatory Determinations for 

Contaminants on the Third Drinking 

Water Contaminant Candidate List, 

closes on December 19, 2014. After 

considering public comments and any 

additional information, EPA expects to 

publish the final, third Regulatory 

Determination in late 2015.
