ENVIRONMENTAL PROTECTION AGENCY
40 CFR Part 52
[EPA-R09-OAR-2007-0610; FRL-8448-7]
Revisions to the Arizona State Implementation Plan, Maricopa
County
AGENCY: Environmental Protection Agency (EPA).
ACTION: Proposed rule.
-----------------------------------------------------------------------
SUMMARY: EPA is proposing to approve revisions to the Maricopa County
portion of the Arizona State Implementation Plan (SIP). This revision
concerns reductions of particulate matter (PM) emissions from the
paving of unpaved road and use of these reductions to satisfy the
offset requirements under the new source review provisions of the Clean
Air Act as amended in 1990 (CAA or the Act). We are proposing to
approve a local rule to assure that the PM emission reductions
resulting from the road paving meet the criteria for valid offsets
under the Act.
DATES: Any comments on this proposal must arrive by September 5, 2007.
ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2007-0610, by one of the following methods:

, including any personal information provided,
unless the comment includes Confidential Business Information (CBI) or
other information whose disclosure is restricted by statute.

SUPPLEMENTARY INFORMATION: This proposal addresses the following local
rule: Maricopa County Air Quality Department Rule 242, ``Emission
Offsets Generated by the Voluntary Paving of Unpaved Roads.'' In the
Rules and Regulations section of this Federal Register, we are
approving this local rule in a direct final action without prior
proposal because we believe these SIP revisions are not controversial.
If we receive adverse comments, however, we will publish a timely
withdrawal of the direct final rule and address the comments in
subsequent action based on this proposed rule.
We do not plan to open a second comment period, so anyone
interested in commenting should do so at this time. If we do not
receive adverse comments, no further activity is planned. For further
information, please see the direct final action.
Dated: July 20, 2007.
Keith Takata,
Acting Regional Administrator, Region IX.
