SUMMARY: EPA is proposing to clarify the description of the Imperial
Valley planning area, an area designated as nonattainment for the
national ambient air quality standard for particulate matter with an
aerodynamic diameter of a nominal 10 microns or less (PM10).
EPA is not proposing to change the boundaries of the PM10
area or the status of the area as a ``serious'' PM10
nonattainment area but is proposing to clarify the description of this
partial county area in the Code of Federal Regulations.

SUPPLEMENTARY INFORMATION: For further information, please see the
direct final rule, of the same title, which is located in the Rules
section of this Federal Register. EPA is clarifying that the ``Imperial
Valley planning area'' PM10 nonattainment area is that
portion of Imperial County that is defined as 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 along the eastern boundary
line of Hydrologic Unit 18100200 to the 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 not take
further action on this proposed rule.
---------------------------------------------------------------------------
\1\ Within Imperial County, the northeastern boundary of
Hydrologic Unit 18100200 generally follows the crestline of
the Chocolate Mountains.
---------------------------------------------------------------------------
If EPA receives adverse comments, EPA will withdraw the direct
final rule, and it will not take effect. EPA will address all public
comments in a subsequent final rule based on this proposed rule. EPA
will not institute a second comment period on this action. Any parties
interested in commenting on this action should do so at this time.
Dated: March 6, 2013.
