ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R09-OAR-2010-0715; FRL-9214-3]
Approval and Promulgation of Implementation Plans--Maricopa
County (Phoenix) PM-10 Nonattainment Area; Serious Area Plan for
Attainment of the 24-Hour PM-10 Standard; Clean Air Act Section 189(d)
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule; extension of comment period.
-----------------------------------------------------------------------
SUMMARY: On September 9, 2010 (75 FR 54806), EPA published a proposed
rule proposing to approve in part and disapprove in part State
implementation plan (SIP) revisions submitted by the State of Arizona
to meet, among other requirements, section 189(d) of the Clean Air Act
(CAA) for the serious Maricopa County (Phoenix) nonattainment area
(Maricopa area). Specifically, EPA proposed to disapprove provisions of
the 189(d) plan because they do not meet applicable CAA requirements
for emissions inventories as well as for attainment, five percent
annual emission reductions, reasonable further progress and milestones,
and contingency measures. EPA also proposed to disapprove the 2010
motor vehicle emission budget in the 189(d) plan as not meeting the
requirements of CAA section 176(c) and 40 CFR 93.118(e)(4). EPA also
proposed a limited approval and limited disapproval of State
regulations for the control of PM-10 from agricultural sources.
Finally, EPA proposed to approve various provisions of State statutes
relating to the control of PM-10 emissions in the Maricopa area.
EPA is extending the comment period on the proposed rule from
October 12, 2010 to October 20, 2010.

SUPPLEMENTARY INFORMATION: On September 9, 2010 (75 FR 54806), EPA
published a proposed rule proposing to approve in part and disapprove
in part State implementation plan (SIP) revisions submitted by the
State of Arizona to meet the Clean Air Act (CAA) requirements
applicable to the serious Maricopa County (Phoenix) nonattainment area
(Maricopa area). These requirements apply to the Maricopa area
following EPA's June 6, 2007 finding that the area failed to meet its
December 31, 2006 serious area deadline to attain the national ambient
air quality standards (NAAQS) for particulate matter of ten microns or
less (PM-10). Under CAA section 189(d), Arizona was required to submit
a plan by December 31, 2007 providing for expeditious attainment of the
PM-10 NAAQS and for an annual emission reduction in PM-10 or PM-10
precursors of not less than five percent per year until attainment
(189(d) plan).
In the Agency's September 9, 2010 proposed rule, EPA proposed to
disapprove provisions of the 189(d) plan for the Maricopa area because
they do not meet applicable CAA requirements for emissions inventories
as well as for attainment, five percent annual emission reductions,
reasonable further progress and milestones, and contingency measures,
and to disapprove the 2010 motor vehicle emission budget in the 189(d)
plan as not meeting the requirements of CAA section 176(c) and 40 CFR
93.118(e)(4). EPA also proposed a limited approval and limited
disapproval of State regulations for the control of PM-10 from
agricultural sources. Finally, EPA proposed to approve various
provisions of State statutes relating to the control of PM-10 emissions
in the Maricopa area.
The September 9, 2010 proposed rule provided a 30-day public
comment period ending on October 12, 2010. In response to a request for
an extension of the comment period from Benjamin H. Grumbles, Director,
Arizona Department of Environmental Quality, and Dennis Smith,
Executive Director, Maricopa Association of Governments, submitted by
letter dated October 4, 2010, EPA is extending the comment period to
October 20, 2010.
Dated: October 7, 2010.

Regional Administrator, EPA Region IX.
