ENVIRONMENTAL PROTECTION AGENCY

Adequacy Status of the Maricopa County Submitted CO Attainment
Plan for Transportation Conformity Purposes
AGENCY: Environmental Protection Agency (EPA).
ACTION: Notice of adequacy.
-----------------------------------------------------------------------
SUMMARY: In this document, EPA is notifying the public that we have
found that submitted Maricopa County Carbon Monoxide (CO) Attainment
Plan is adequate for conformity purposes. As a result of our finding,
the Maricopa Association of Governments and the Federal Highway
Administration are required to use the CO motor vehicle emissions
budget from the submitted CO Attainment Plan for future conformity
determinations. This determination is effective December 14, 1999.
DATES: This budget is effective December 14, 1999.
FOR FURTHER INFORMATION CONTACT: The finding and the response to
comments are available at EPA's conformity website: http://www.epa.gov/
oms/traq, (once there, click on the ``Conformity'' button, then look
for ``Adequacy Review of SIP Submissions for Conformity''). You may
also contact Karina O'Connor, U.S. EPA, Region IX, Air Division AIR-2,
75 Hawthorne Street, San Francisco, CA 94105; (415) 744-1247 or
[email protected].
SUPPLEMENTARY INFORMATION:
Today's document is simply an announcement of a finding that we
have already made. EPA Region IX sent a letter to the Arizona
Department of Environmental Quality on November 5, 1999 stating that
the submitted Maricopa County CO Attainment Plan is adequate for
conformity purposes. This finding has also been announced on our
conformity website: http://www.epa.gov/oms/traq, (once there, click on
the ``Conformity'' button, then look for ``Adequacy Review of SIP
Submissions for Conformity'').
Transportation conformity is required by section 176(c) of the
Clean Air Act. Our conformity rule requires that transportation plans,
programs, and projects conform to state air quality implementation
plans (SIPs) and establishes the criteria and procedures for
determining whether or not they do. Conformity to a SIP means that
transportation activities will not produce new air quality violations,
worsen existing violations, or delay timely attainment of the national
ambient air quality standards.
The criteria by which we determine whether a SIP's motor vehicle
emission budgets are adequate for conformity purposes are outlined in
40 CFR 93.118(e)(4). Please note that an adequacy review is separate
from our completeness review which is required by section 110(k)(1) of
the Clean Air Act, and it also should not be used to prejudge EPA's
ultimate approval of the SIP. Even if we find a budget adequate, the
SIP could later be disapproved.
We've described our process for determining the adequacy of
submitted SIP budgets in guidance (May 14, 1999 memo titled
``Conformity Guidance on Implementation of March 2, 1999 Conformity
Court Decision''). We followed this guidance in making our adequacy
determination.
Authority: 42 U.S.C. 7401-7671q.
Dated: November 8, 1999.

Regional Administrator, Region IX.
