16826 Federal Register / Vol. 78, No. 53 / Tuesday, March 19, 2013 / Proposed Rules 

1Please refer to 78 FR 8274 (February 5, 2013) for 

additional background information related to NGS, 

regional haze and the protection of visibility at 

mandatory Class I federal areas, and the statutory 

and regulatory framework for addressing visibility 

impairment from sources located in Indian country. 

2The CAWCD manages the Central Arizona 

Project, a water delivery system that relies on 

electricity from NGS to pump surface water from 

the Colorado River for use by numerous tribes in 

Arizona, as well as agricultural, municipal, and 

industrial water users. Please refer to 78 FR 8274 

(February 5, 2013) for additional information about 

CAWCD and its relationship to NGS and tribes 

located in Arizona. 

designated as Class I federal areas, 

mandated by Congress to receive 

heightened protection. NGS is subject to 

the BART requirement of the CAA and 

the Regional Haze Rule based on its age 

and its effects on visibility in Class I 

areas.1

On February 5, 2013, EPA proposed a 

BART determination to require NGS to 

achieve a nearly 80 percent reduction of 

its current overall NOX emission rate. 

EPA also proposed an alternative to 

BART that would provide flexibility to 

NGS in the schedule for the installation 

of new post-combustion control 

equipment. EPA’s proposed alternative 

to BART credits NGS for its early and 

voluntary installation of new 

combustion controls to reduce NOX

emissions beginning in 2009 and 

therefore achieves greater reasonable 

progress than BART. 

In recognition that there may be other 

approaches that could result in 

equivalent or better visibility benefits 

than BART, as well as the singular 

importance of NGS to the Navajo 

Nation, Hopi Tribe, and other numerous 

tribes located in Arizona, EPA also 

outlined a framework for evaluating 

other alternatives to provide greater 

flexibility than EPA’s proposed 

alternative to BART. EPA requested 

comment on Alternatives 2 and 3 that 

provide until 2025 or 2026 for 

compliance but would require the 

owners of NGS to implement additional 

emission reductions in order to assure 

greater reasonable progress than would 

otherwise be achieved under BART. 

EPA encouraged a robust public 

discussion of our proposed BART 

determination and alternative, as well as 

Alternatives 2 and 3, and recognized the 

potential need for a supplemental 

proposal if Alternatives 2 or 3, or other 

approaches developed by other parties, 

are identified as meeting the needs of 

stakeholders and meeting the 

requirements of the CAA. 

On February 15, 2013, Salt River 

Project (SRP), co-owner and operator of 

NGS, requested a 90-day extension of 

the public comment period. SRP stated 

that identifying and analyzing 

alternatives and discussing options with 

interested parties would require a 

significant amount of time. On February 

21, 2013, the Central Arizona Water 

Conservation District (CAWCD) 

submitted a similar request for a 90-day 

extension of the comment period.2 On 

March 1, 2013, the Navajo Nation also 

requested a 90-day extension of the 

comment period in order to allow the 

Navajo Nation the time and opportunity 

to participate with NGS owners and 

other stakeholders in examining the 

feasibility of additional alternatives, 

including Alternatives 2 and 3. 

II. Today’s Action 

EPA recognizes that the stakeholder 

process, to develop viable alternatives to 

BART that provide additional flexibility 

to the owners of NGS while achieving 

more emission reductions to assure 

greater reasonable progress than BART, 

will require a significant amount of 

time. EPA also recognizes the critical 

importance of active participation by 

the Navajo Nation, the Hopi Tribe, and 

other affected tribes located in Arizona 

in the development of alternatives to 

BART. Therefore, EPA is extending the 

comment period by an additional 90 

days.

follows: Commencing at the southwest 

corner of Imperial County and 

extending north along the Imperial-San 

Diego County line to the northwest 

corner of Imperial County; then east 

along the Imperial-Riverside County 

line to the point of intersection of the 

eastern boundary line of Hydrologic 

Unit #18100200 1; then southeasterly

Imperial County-Mexico Border; then 

west along the Imperial County-Mexico 

Border to the point of the beginning. 

EPA is publishing this action as a direct 

final rule without prior proposal 

because EPA views this action as 

noncontroversial and anticipates no 

adverse comments. A detailed rationale 

for this action is set forth in the 

preamble to the direct final rule. If EPA 

receives no adverse comments, EPA will
