40 CFR Part 52

[CO-001-0025b; FRL-6319-8]


Approval and Promulgation of Air Quality Implementation Plans; 
Colorado; Removal and Replacement of Transportation Control Measure, 
Colorado Springs Element, Carbon Monoxide Section of the State 
Implementation Plan

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing approval of a revision to the Colorado State 
Implementation Plan (SIP), carbon monoxide (CO) section, Colorado 
Springs element. In a June 25, 1996, submission, Colorado requests that 
emission reductions from oxygenate use in gasoline be substituted for 
reductions associated with the previously approved (48 FR 55284, 
December 12, 1983) bus acquisition program because the bus program was 
not implemented due to the lack of federal funding. This revision 
satisfies certain requirements of part D and section 110 of the Clean 
Air Act (CAA), as amended in 1990. In the Final Rules section of this 
Federal Register, EPA is approving the State's SIP revision as a direct 
final rule without prior proposal because the Agency views this as a 
noncontroversial SIP revision 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 proposed 
rule, no further activity is contemplated in relation to this rule. 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EPA receives adverse comments, the direct final rule will be withdrawn 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. EPA will not institute a second 
comment period on this action. Any parties interested in commenting on 
this action should do so at this time.

DATES: Comments on this proposed rule must be received in writing by 
May 10, 1999.

ADDRESSES: Written comments may be mailed to: Richard R. Long, 
Director, Air and Radiation Program (8P-AR), United States 
Environmental Protection Agency, Region VIII, 999 18th Street, Suite 
500, Denver, Colorado 80202-2466.
