40 CFR Part 52

[IL104–1–6697b; FRL–5158–8]

Approval and Promulgation of

Implementation Plans; Illinois

AGENCY: Environmental Protection

Agency (USEPA).

ACTION: Proposed rule.

SUMMARY: The United States

Environmental Protection Agency

(USEPA) proposes to approve Illinois’

November 28, 1994, request to amend

the marine vessel loading rules for the

Chicago and Metro-East areas as part of

the State’s 15 percent (%) Rate of

Progress Plan control measures for

Volatile Organic Matter emissions. The

control measures require marine

terminals, from May 1 through

September 15, to operate a vapor

collection and control system which

achieves a 95% control efficiency. In the

final rules section of this Federal

Register, the USEPA is approving this

action as a direct final rule without

prior proposal because USEPA views

this as a noncontroversial action 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 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final rule will be withdrawn and all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 the proposed rule. USEPA will

not institute a second comment period

on this action. Any parties interested in

commenting on this notice should do so

at this time.

DATES: Comments on this proposed rule

must be received on or before May 3,

1995.

ADDRESSES: Written comments should

be mailed to: J. Elmer Bortzer, Chief,

Regulation Development Section,

Regulation Development Branch (AR18–

J), U.S. Environmental Protection

Agency, 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

BILLING CODE 6560–50–P

40 CFR Part 52

[MO–20–1–6442; FRL–5181–8]

Approval and Promulgation of

Implementation Plans; State of

Missouri

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: The Environmental Protection

Agency (EPA) proposes to approve the

State Implementation Plan (SIP)

revision by the state of Missouri that

revises the Missouri Part D new source

review (NSR) rules, updates and adds

numerous definitions, revises the

maximum allowable increase for

particulate matter under the

requirements for prevention of

significant deterioration (PSD) of air

quality, address emission statements

under title I of the Clean Air Act

Amendments (CAAA), and generally

enhance the SIP.

This revision generally meets

requirements of the Clean Air Act (CAA)

as Amended in 1990 with regard to NSR

in areas that have not attained the

national ambient air quality standard

(NAAQS). However, Missouri is

required to make certain changes to the

NSR rules, as outlined in this proposal,

before EPA can grant final approval to

this SIP revision. This implementation

plan was submitted by the state to

satisfy certain Federal requirements for

an approvable nonattainment NSR SIP

for Missouri.

DATES: Comments must be received on

or before May 3, 1995.

ADDRESSES: Comments may be mailed to

Robert J. Lambrechts, Environmental

Protection Agency, Air Branch, 726

Minnesota Avenue, Kansas City, Kansas

66101.

SUPPLEMENTARY INFORMATION:

I. Background

The air quality planning requirements

for nonattainment NSR are set out in

part D of title I of the Act. EPA has

issued a ‘‘General Preamble’’ describing

EPA’s preliminary views on how EPA

intends to review SIP revisions

submitted under part D, including those

state submittals containing

nonattainment area NSR SIP

requirements (see 57 FR 13498 (April

16, 1992) and 57 FR 18070 (April 28,

1992)). Because EPA is describing its

interpretations here only in broad terms,

the reader should refer to the General

Preamble for a more detailed discussion

of the interpretations of part D advanced

in today’s proposal and the supporting

rationale.

The EPA is currently developing a

proposed rule to assist the

implementation of the changes under

the amended Act in the NSR provisions

in parts C and D of title I of the Act. If

EPA has not taken final action on the

state’s NSR submittals by the time the

proposed rule is published for

comment, EPA may refer to the

proposed rule as the most authoritative

guidance available regarding the

approvability of the submittals. Upon

promulgation of the final regulations,

EPA will review the NSR SIPs of all

states to determine whether additional

SIP revisions are necessary.

Prior to EPA approval of a state’s NSR

SIP submission, the state may continue

permitting only in accordance with the

new statutory requirements for permit

applications completed after the

relevant SIP submittal date. This policy

was explained in transition guidance

memoranda from John Seitz dated

March 11, 1991, and September 3, 1992.

As explained in the March 11

memorandum, EPA does not believe

Congress intended to mandate the more

stringent Title I NSR requirements

during the time provided for SIP

development. States were thus allowed

to continue to issue permits consistent

with requirements in their current NSR

SIPs during that period; or apply 40 CFR

part 51, appendix S for newly
