Approval and Promulgation of Air

Quality Implementation Plans; Texas;

Revision to the State Implementation

Plan Addressing Sulfur Dioxide in

Harris County

AGENCY: Environmental Protection

Agency (EPA).

ACTION: Proposed rule.

SUMMARY: The EPA in this action

proposes to approve a revision to the

Texas State Implementation Plan (SIP)

to include Agreed Orders limiting sulfur

dioxide (SO2) allowable emissions at

certain nonpermitted facilities in Harris

County, Texas. In the final rules section

of this Federal Register, the EPA is

approving the State’s SIP revision 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 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 the 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will be withdrawn, and all public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. The 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 April 5,

1995.

ADDRESSES: Written comments on this

action should be addressed to Mr.

Thomas H. Diggs, Chief, Planning

Section, at the EPA Regional Office

listed below. Copies of the documents

relevant to this action are available for

public inspection during normal

business hours at the following

locations. The interested persons

wanting to examine these documents

should make an appointment with the

appropriate office at least twenty-four

hours before the visiting day.

SUPPLEMENTARY INFORMATION:

I. Background

On April 21, 1993, the Agency

published final Retrofit/Rebuild

Requirements for 1993 and Earlier

Model Year Urban Buses (58 FR 21359).

The retrofit/rebuild requirements are

intended to reduce the ambient levels of

particulate matter (PM) in urban areas

and are limited to 1993 and earlier

model year (MY) urban buses operating

in metropolitan areas with 1980

populations of 750,000 or more, whose

engines are rebuilt or replaced after

January 1, 1995. Operators of the

affected buses are required to choose

between two compliance programs:

Program 1 sets particulate matter

emissions requirements for each urban

bus engine in an operator’s fleet which

is rebuilt or replaced; Program 2 is a

fleet averaging program that sets out a

specific annual target level for average

PM emissions from urban buses in an

operator’s fleet.

A key aspect of this regulation is the

certification of retrofit/rebuild
