ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 81

[EPA-R09-OAR-2010-0718; FRL-9219-8]


Determinations of Attainment by the Applicable Attainment Date 
for the Hayden, Nogales, Paul Spur/Douglas PM10 
Nonattainment Areas, Arizona

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: EPA proposes to determine that the Hayden, Nogales, and Paul 
Spur/Douglas nonattainment areas in Arizona attained the National 
Ambient Air Quality Standard (NAAQS) for particulate matter with an 
aerodynamic diameter of less than or equal to a nominal ten micrometers 
(PM10) by the applicable attainment date of December 31, 
1994. On the basis of this proposed determination, EPA concludes that 
these three ``moderate'' nonattainment areas are not subject to 
reclassification by operation of law to ``serious.'' Lastly, on the 
basis of a review of more recent ambient monitoring data, EPA also is 
proposing to determine that the Hayden, Nogales and Paul Spur/Douglas 
nonattainment areas are not currently attaining the PM10 
standard.

DATES: Comments must be received on or before December 2, 2010.

ADDRESSES: Submit comments, identified by docket number EPA-R09-OAR-
2010-0718, by one of the following methods:

section of this Federal Register for detailed instructions on how to 
submit comments.

IX address.

SUPPLEMENTARY INFORMATION: For further information, please see the 
direct final action, of the same title, which is located in the Rules 
section of this Federal Register. EPA is determining that the Hayden, 
Nogales, and Paul Spur/Douglas nonattainment area attained the 
PM10 standard by the applicable attainment date (1994), and 
that the three areas are not currently attaining the standard, as a 
direct final rule without prior proposal because EPA views this as a 
noncontroversial action and anticipates no adverse comments. A detailed 
rationale for the determinations 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.
    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. 
Please note that if we receive adverse comment on one of the 
determinations, EPA may adopt as final those determinations that are 
not the subject of an adverse comment.

    Dated: October 25, 2010.

Regional Administrator, EPA Region IX.
