ENVIRONMENTAL PROTECTION AGENCY

40 CFR Part 52

[AK10-1-7022b; FRL-6163-1]


Approval and Promulgation of State Implementation Plans: Alaska

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: The EPA is approving the State Implementation Plan (SIP) 
revision submitted by the State of Alaska for the purpose of revising 
the mobile source category of the 1990 base year inventory. The SIP 
revision was submitted by the State when an improved model for 
estimating mobile source emissions became available. 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 submittal amendment and 
anticipates no adverse comments. A detailed rationale for the approval 
is set forth in the direct final rule. If no adverse comments are 
received in response to this action, no further activity is 
contemplated in relation to this rule. If the 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comments, the direct final rule will be withdrawn and all public 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 on this action should do so at 
this time.

DATES: Comments must be received in writing by October 23, 1998.

ADDRESSES: Written comments should be addressed to Montel Livingston, 
Environmental Protection Specialist, Office of Air Quality (OAQ-107), 
at the EPA Regional Office listed below. Copies of the documents of the 
state submittal are available at the following addresses for inspection 
during normal business hours. Interested persons wanting to examine 
these documents should make an appointment with the appropriate office 
at least 24 hours before the visiting day. Environmental Protection 
Agency, Region 10, Office of Air Quality, 1200 Sixth Avenue, Seattle, 
WA 98101, and the Alaska Department of Environmental Conservation, 410 
Willoughby, Room 105, Juneau, Alaska.

FOR FURTHER INFORMATION CONTACT: Joan Cabreza, Environmental Scientist, 
Office of Air Quality (OAQ-107), EPA, 1200 Sixth Avenue, Seattle, WA
