ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[CA/AZ 211-0126 EC; FRL-6235-6]


Approval and Promulgation of State Implementation Plans; 
California and Arizona State Implementation Plan Revisions: Maricopa 
County, Arizona; Antelope Valley Air Pollution Control District, San 
Diego County Air Pollution Control District, San Joaquin Valley Unified 
Air Pollution Control District, and Ventura County Air Pollution 
Control District

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed Rule.

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

SUMMARY: EPA is approving revisions to the Arizona and California State 
Implementation Plans (SIP) which concern the control of emergency air 
episodes.
    The intended effect of this action is to protect the public from 
sudden and dangerous emissions of criteria pollutants 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, the EPA 
is approving the states' SIP submittals 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, 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receives adverse comments, the direct final rule will be withdrawn and 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 April 19, 1999.

ADDRESSES: 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.

rule are available for public inspection at EPA's Region 9 office 
during normal business hours. Copies of the submitted rule revisions
