40 CFR Part 52

[AZ 086-0207b; FRL-6710-6]


Approval and Promulgation of Implementation Plans; Arizona State 
Implementation Plan Revision, Maricopa County Environmental Services 
Department

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a revision to the Maricopa County 
Environmental Services Department (MCESD) portion of the Arizona State 
Implementation Plan (SIP). This revision concerns volatile organic 
compound (VOC) emissions from ferrous sand casting operations. We are 
proposing to approve a local rule to regulate this emission source 
under the Clean Air Act as amended in 1990 (CAA or the Act).

DATES: Any comments on this proposal must arrive by July 12, 2000.

ADDRESSES: Mail comments to Andrew Steckel, Rulemaking Office Chief 
(AIR-4), U.S. Environmental Protection Agency, Region IX, 75 Hawthorne 
Street, San Francisco, CA 94105.
    You can inspect copies of the submitted rule and EPA's technical 
support documents (TSDs) at our Region IX office during normal business 
hours. You may also see copies of the submitted rule at the following 
locations:

Arizona Department of Environmental Quality, 3033 North Central Avenue, 
Phoenix, AZ 85012
Maricopa County Environmental Services Department, Air Quality 
Division, 1001 North Central Avenue, Suite 201, Phoenix, AZ 85004

FOR FURTHER INFORMATION CONTACT: Al Petersen, Rulemaking Office (AIR-
4), Air Division, U.S. Environmental Protection Agency, Region IX, 75 
Hawthorne Street, San Francisco, CA 94105-3901, (415) 744-1135.

SUPPLEMENTARY INFORMATION: This proposal addresses the following local 
rule: MCESD Rule 347. 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 this SIP revision is 
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: May 12, 2000.
Laura Yoshii,
Acting Regional Administrator, Region IX.
