SUPPLEMENTARY INFORMATION: On October 19, 2010, the Region 9 Office of
the United States Environmental Protection Agency (EPA) proposed a
Source Specific Federal Implementation Plan to implement the Best
Available Retrofit Technology for Four Corners Power Plant, located on
the Navajo Nation (75 FR 64221). The Clean Air Act's Regional Haze Rule
requires the use of Best Available Retrofit Technology (BART) at older
coal-fired power plants to reduce haze and improve visibility.
On November 12, 2010, EPA published in the Federal Register (75 FR
69373) a notice of three sets of open houses and public hearings to be
held at three locations in the Four Corners Area on December 6-9, 2010.
EPA is postponing the open houses and public hearings and will provide
additional notice and details of the rescheduled hearings at a later
time.
EPA published notices of open houses and public hearings, to be
held December 7-9, 2010 in Shiprock, NM, Farmington, NM, and Durango,
CO, in the Farmington Daily Times and the Durango Herald on November 3,
2010 and the Navajo Times on November 4, 2010. Notice of these hearings
was additionally published in the Federal Register on November 12, 2010
(75 FR 69373). On Thursday, November 11, 2010, EPA published notice in
the Navajo Times of an additional open house and public hearing to be
held at the Nenahnezad Chapter House in Fruitland, NM. The public
comment period for the proposal was scheduled to close on December 20,
2010.
EPA proposed requiring the Four Corners Power Plant to meet a
plant-wide limit of 0.11 lb/MMBtu, representing an 80% reduction in
emissions of nitrogen oxides (NOX) to achieve cleaner,
healthier air while improving the visibility at sixteen of our most
pristine national parks and wilderness areas. EPA's proposal can be
achieved by installing and operating selective catalytic reduction
(SCR) on all five units. EPA is also proposing a particulate matter
(PM) emission limit of 0.012 lb/MMBtu for the three smaller units that
will require additional controls for fine particles, and is also
requesting comment on whether BART can be met on the three smaller
units by requiring an emission limit of 0.03 lb/MMBtu with a 20%
opacity limit. Reduction of fine particles may help reduce the visible
secondary plume that is often emanating from these three units. For the
two larger units at Four Corners Power Plant, EPA is proposing an
emission limit of 0.015 lb/MMBtu, achievable with proper operation of
the existing baghouses.
On November 9, 2010, EPA met with representatives from Arizona
Public Service (APS), co-owner and operator of FCPP. APS discussed an
alternative proposal that calls for shutting down Units 1-3 at FCPP by
2014 and installing SCR on Units 4 and 5 by 2018. APS claims this plan
will result in larger emissions reductions than EPA's proposal without
layoffs at the facility. A record of this meeting has been posted to
the docket for this proposed rulemaking. APS plans to submit their
alternative proposal and supporting analysis to EPA shortly. EPA will
make this submittal from APS available from our docket when it is
received. The link to the docket can be reached at the following Web
site: http://www.epa.gov/region9/air/navajo/index.html#proposed or from
http://www.regulations.gov, identified by EPA Docket Number: EPA-R09-
OAR-2010-0683.
EPA is extending the public comment period for our proposal to
March 18, 2011 and postponing the scheduled open houses and public
hearings to allow EPA and the public time to assess the alternative
proposal submitted by APS. EPA may supplement our proposal with
additional information following our analysis of APS' submission. If
EPA supplements our original proposal, we will publish the supplement
in the Federal Register and provide supporting documentation in our
docket. The dates for the rescheduled open houses and public hearings
have
[[Page 76332]]
not yet been determined, but EPA will provide notice of the rescheduled
open houses and hearings in local newspapers, in our docket, and on our
Web site at least 30 days prior to the events.
EPA's proposed rule was published in the Federal Register on
October 19, 2010 (75 FR 64221) and can be accessed the following Web
site: http://www.epa.gov/region9/airnavajo/index.html#proposed. EPA has
established a public docket for the proposed rulemaking under the
docket number EPA-R09-OAR-2010-0683.
Docket: The index to the docket for this action is available
electronically at http://www.regulations.gov and in hard copy at EPA
Region IX, 75 Hawthorne Street, San Francisco, California. While all
documents in the docket are listed in the index, some information may
be publicly available only at the hard copy location (e.g., copyrighted
material), and some may not be publicly available in either location
(e.g., CBI). Due to building security procedures, to inspect the hard
