ENVIRONMENTAL PROTECTION

AGENCY

40 CFR Part 52

[OH61–1–6381b; FRL–5175–3]

Approval and Promulgation of

Implementation Plans; Ohio

AGENCY: United States Environmental

Protection Agency (USEPA).

ACTION: Proposed rule.

SUMMARY: The USEPA is taking action to

approve, through direct final procedure,

Ohio’s 1990 base-year ozone precursor

emissions inventory for the Toledo and

Dayton ozone nonattainment areas as

revisions to the ozone portion of the

Ohio State Implementation Plan (SIP).

The emissions inventories were

submitted to satisfy a Federal

requirement that States containing

ozone nonattainment areas submit

inventories of actual ozone precursor

emissions for the year 1990. The Ohio

ozone nonattainment areas covered by

this rulemaking are Toledo (Lucas and

Wood Counties) and Dayton (Clark,

Greene, Miami, and Montgomery

Counties).

In the final rules section of this

Federal Register, USEPA is approving

the State’s SIP revision request as a

direct final rule without prior proposal

because USEPA views this as

noncontroversial and anticipates no

adverse comments. A detailed rationale

for the approval is set forth in the direct

final rule. If no adverse or critical

comments are received in response to

that direct final rule, no further activity

is contemplated in relation to this

proposed rule. If USEPA 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will be withdrawn and all public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. USEPA will institute a

second comment period on this action

only if warranted by revisions to the

rulemaking based on comments

received. Any parties interested in

commenting on this action should do so

at this time.

DATES: Comments on this action must be

received by April 21, 1995.

ADDRESSES: Written comments should

be mailed to: William L. MacDowell,

Chief, Regulation Development Section,

Air Enforcement Branch (AE–17J),

USEPA, Region 5, 77 West Jackson

Boulevard, Chicago, Illinois 60604.

Copies of the State submittal and

USEPA’s analysis of it are available for

inspection at: Regulation Development

Section, Air Enforcement Branch (AE–

17J), USEPA, Region 5, 77 West Jackson

Boulevard, Chicago, Illinois 60604.

[MT26–1–6692b; FRL–5163–9]

Clean Air Act Approval and

Promulgation of State Implementation

Plan for Montana; Butte; PM10

Contingency Measures and Revisions

to the Attainment and Maintenance

Demonstrations

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: EPA proposes to approve the

State implementation plan (SIP)

revisions submitted by the State of

Montana with a letter dated August 26,

1994. This submittal addresses, for the

Butte moderate PM10 nonattainment

area, the Federal Clean Air Act

requirement to submit contingency

measures for particulate matter with an

aerodynamic diameter less than or equal

to a nominal 10 micrometers (PM10) for

areas designated as nonattainment for

the PM10 National Ambient Air Quality

Standards (NAAQS). This submittal also

includes revisions to the attainment and

maintenance demonstrations for the

moderate PM10 nonattainment area SIP

for Butte due to the inclusion of new

emission limits in a revised air quality

permit for Montana Resources, Inc.

Since the SIP adequately addresses the

requirement for contingency measures

and, with the new emission limits for

Montana Resources, Inc., still

adequately demonstrates attainment and

maintenance of the PM10 NAAQS in

Butte, EPA proposes to approve these

revisions.

In the final rules section of this

Federal Register, EPA is acting on the

State’s SIP revisions as a direct final

rule without prior proposal because the

Agency views this as a noncontroversial

revision amendment and anticipates no

adverse comments. A detailed rationale

for EPA’s actions 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 and the direct final rule

will become effective. 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 document should do so at this

time.

DATES: Comments on this proposed rule

must be received in writing by April 21,

1995.

ADDRESSES: Written comments on this

action should be addressed to Amy

Platt, 8ART–AP, at the EPA Regional

Office listed below. Copies of the State’s

submittal and documents relevant to

this proposed rule are available for

inspection during normal business

hours at the following locations: Air

Programs Branch, Environmental

Protection Agency, Region VIII; 999
