ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 63

[FRL-6175-3]


Delegation of National Emission Standards for Hazardous Air 
Pollutants for Source Categories; State of Arizona; Pinal County Air 
Quality Control District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: Pursuant to section 112(l) of the 1990 Clean Air Act (CAA), 
the Pinal County Air Quality Control District (PCAQCD) requested 
delegation of specific national emission standards for hazardous air 
pollutants (NESHAPs). In the Rules section of this Federal Register, 
EPA is granting PCAQCD the authority to implement and enforce specified 
NESHAPs. The direct final rule also explains the procedure for future 
delegation of NESHAPs to PCAQCD. EPA is taking direct final action 
without prior proposal because the Agency views this as a 
noncontroversial action 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, no further activity is contemplated. 
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withdrawn and all public comments received will be addressed in a 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. Any parties interested in commenting 
should do so at this time.

DATES: Written comments must be received by December 18, 1998.

ADDRESSES: Written comments should be addressed to: Andrew Steckel, 
Rulemaking Office (AIR-4), Air Division, U.S. Environmental Protection 
Agency, Region IX, 75 Hawthorne Street, San Francisco, CA 94105-3901.
    Copies of the submitted requests are available for public 
inspection at EPA's Region IX office during normal business hours 
(docket number A-96-25).

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

SUPPLEMENTARY INFORMATION: This document concerns delegation of 
unchanged NESHAPs to the Pinal County Air Quality Control District. For 
further information, please see the information provided in the direct 
final action which is located in the Rules section of this Federal 
Register.

    Authority: This action is issued under the authority of Section 
112 of the Clean Air Act, as amended, 42 U.S.C. Section 7412.

    Dated: September 28, 1998.
