2982 Federal Register / Vol. 61, No. 20 / Tuesday, January 30, 1996 / Proposed Rules

for carbon monoxide (CO). Under the

Clean Air Act as amended in 1990

(CAA), designations can be revised if

sufficient data is available to warrant

such revisions.

In addition, EPA is proposing

approval of two related State

Implementation Plan (SIP) submissions

by Massachusetts DEP. On November

15, 1993, Massachusetts DEP submitted

a final 1990 base year emission

inventory for CO emissions, which

includes emissions data for all sources

of CO in Massachusetts’ CO

nonattainment areas, as well as CO

emissions for the entire State. On

October 29, 1993, Massachusetts DEP

submitted an oxygenated fuel program

for the Boston consolidated

metropolitan statistical area (CMSA).

In the Final Rules Section of this

Federal Register, EPA is approving the

CO emissions inventory and the

oxygenated fuels program as a direct

final rule.

In addition, EPA is also approving

Massachusetts’ redesignation request as

a direct final rule without prior

proposal. A detailed rationale for the

action is set forth in the direct final rule,

including a modification in national

policy regarding the need for a

conformity SIP submission prior to

redesignation of an area. If no adverse

comments are received in response to

that direct final rule, no further activity

is contemplated in relation to this

proposed 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withdrawn and all public comments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 notice.

Any parties interested in commenting

on this notice should do so at this time.

DATES: Comments must be received by

February 29, 1996.

ADDRESSES: Written comments should

be sent to Susan Studlien, Acting

Director of the Air, Pesticides and

Toxics Management Division, at the

EPA Regional Office listed below.

Copies of the redesignation request and

the State of Massachusetts’ submittal are

available for public review during

normal business hours at the addresses

ACTION: Proposed rule.

SUMMARY: EPA proposes to approve the

State Implementation Plan (SIP)

revision submitted by the

Commonwealth of Pennsylvania for the

purpose of approving a maintenance

plan, the 1990 base year carbon

monoxide (CO) emissions inventory for

Philadelphia County and a request to

redesignate the Philadelphia County

carbon monoxide nonattainment area,

from nonattainment to attainment for

CO. In the Final Rules section of this

Federal Register, EPA is approving the

Commonwealth’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 must be received in

writing by February 29, 1996.

ADDRESSES: Written comments on this

action should be addressed to Marcia L.
