ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[AZ 68-0011; FRL-5835-7]


Approval and Promulgation of State Implementation Plans; 
Arizona--Maricopa County Ozone Nonattainment Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the State of Arizona on April 29, 1997, 
establishing a summertime gasoline Reid Vapor Pressure (RVP) limit of 
7.0 pounds per square inch (psi) for gasoline distributed in the 
Maricopa (Phoenix) ozone nonattainment area. Arizona has lowered the 
summertime RVP limit for this area to reduce emissions of volatile 
organic compounds (VOC) in accordance with the requirements of the

[[Page 31776]]

Clean Air Act, as amended in 1990 (CAA). Arizona's fuel requirement is 
not preempted by federal fuels requirements because EPA is proposing to 
find that the control measure is necessary for the Maricopa area to 
attain the national ambient air quality standards (NAAQS) for ozone and 
is proposing to approve the measure into the Arizona SIP.
    In the final rules section of this Federal Register, the EPA is 
approving the State's SIP revision as a direct final rule without prior 
proposal because the Agency views this as a noncontroversial revision 
and anticipates no adverse comments. A detailed rationale for this 
approval is set forth in the direct final rule. If no adverse comments 
are received in response to this proposed rule, no further activity is 
contemplated in relation to this rule. If EPA receives adverse 
comments, the direct final rule will be withdrawn and all public 
comments received will be addressed in a subsequent final rule based on 
this proposed rule. The EPA will not institute a second comment period 
on this document. Any parties interested in commenting on this action 
should do so at this time.

DATES: Comments on this proposed rule must be received in writing by 
July 11, 1997.

ADDRESSES: Written comments should be sent to the Region IX contact 
listed below. Copies of the SIP revision are available in the docket 
(#AZ-RVP-97) for this rulemaking, which is open for public inspection 
at the addresses below. A copy of this notice is also available on EPA, 
Region IX's website at http://www.epa.gov/region09.

SUPPLEMENTARY INFORMATION: The revision is being proposed for approval 
into the Arizona SIP in section 13 of Arizona House Bill 2001 that adds 
to Arizona Revised Statutes (ARS) section 41-2083(E) 1 
(summertime fuel requirement to limit RVP gasoline to 7.0 psi). This 
revision was submitted by the ADEQ to EPA on April 29, 1997.
