ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[EPA-R09-OAR-2011-0169; FRL-9286-9]

Approval and Promulgation of Implementation Plans; Nevada; 
Determination of Attainment for the Clark County 8-Hour Ozone 
Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to determine that the Clark County (Nevada) 8-
hour ozone nonattainment area has attained the 1997 8-hour ozone 
national ambient air quality standards (NAAQS). This proposed 
determination is based upon complete, quality-assured, and certified 
ambient air monitoring data that show the area has monitored attainment 
of the 1997 8-hour ozone NAAQS for the 2007 to 2009 monitoring period. 
Preliminary air quality monitoring data available for 2010 are 
consistent with continued attainment. Based on this proposed 
determination, the requirement for the State of Nevada to submit an 
attainment demonstration and associated reasonably available control 
measures (RACM), a reasonable further progress (RFP) plan, contingency 
measures, and other planning requirements related to attainment of the 
1997 8-hour ozone NAAQS for the Clark County ozone nonattainment area 
would be suspended for as long as the nonattainment area continues to 
meet the 1997 8-hour ozone NAAQS. This action is being taken under the 
Clean Air Act (CAA).

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 approving the attainment 
determination and related suspension of attainment planning-related SIP 
submittal requirements 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 determination and 
suspension of attainment-related SIP submittal requirements 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 an amendment, 
paragraph, or section of this rule and if that provision may be severed 
from the remainder of the rule, EPA may adopt as final those provisions 
of the rule that are not the subject of an adverse comment.

    Dated: March 15, 2011.
Jared Blumenfeld,
Regional Administrator, EPA Region IX.
