[CT50-7201a; A-1-FRL-6168-8]

Approval and Promulgation of Air Quality Implementation Plans and

Designations of Areas for Air Quality Planning Purposes; State of

Connecticut; Approval of Maintenance Plan, Carbon Monoxide

Redesignation Plan and Emissions Inventory for the New Haven-Meriden-

Waterbury Area

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is approving a redesignation request and emissions

inventory submitted by the State of Connecticut to redesignate the New

Haven-Meriden-Waterbury area to attainment for carbon monoxide. Under

the Clean Air Act amendments of 1990 (CAA), designations can be revised

if sufficient data is available to warrant such revisions. This

revision establishes the area as attainment for carbon monoxide and

requires the state to implement their 10 year maintenance plan. In

addition, EPA is approving the emissions inventory for carbon monoxide

for the New Haven-Meriden-Waterbury area. In the Federal Register, EPA

is approving the redesignation request as direct final rule without

prior proposal because the Agency views this as a noncontroversial

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 that direct final rule, no further

activity is contemplated in relation to this proposal. If EPA receives

adverse comments, the direct final rule will be withdrawn in a timely

manner and all public comments received will be addressed in a

subsequent final rule based on this proposal. EPA will not institute a

second comment period. Any parties interested in commenting on this

rule should do so at this time.

DATES: Comments must be received on or before November 4, 1998.

ADDRESSES: Comments may be mailed to Susan Studlien, Deputy Director,

Office of Ecosystem Protection (mail code CAA), U.S. Environmental

Protection Agency, Region I, JFK Federal Bldg., Boston, MA 02203-2211.

Copies of the State submittal and EPA's technical support document are

available for public inspection during normal business hours, by

Protection Agency, Region I, One Congress Street, 11th floor, Boston,
