ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[AZ 086-0018b; FRL-6468-7]


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

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA proposes to approve revisions to the Arizona State 
Implementation Plan (SIP) which concern the control of particulate 
matter (PM) emissions from residential wood combustion.
    The intended effect of this action is to regulate emissions of PM 
in accordance with the requirements of the Clean Air Act, as amended in 
1990 (CAA or the Act). In the Final Rules section of this Federal 
Register, EPA has published a direct final rulemaking fully approving 
these revisions without prior proposal because the Agency views them as 
noncontroversial revisions and anticipates no adverse comments. A 
detailed rationale for this approval is set forth in the direct final 
rule. If no relevant adverse comments are received, no further activity 
is contemplated in relation to this rule. If EPA receives relevant 
adverse comments, the direct final rule will not take effect and all 
public comments received will be addressed in a subsequent final rule 
based on this proposed rule. EPA will not institute a second comment 
period on this rule. Any parties interested in commenting on this rule 
should do so at this time.

DATES: Comments must be received in writing by December 8, 1999.

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.
