Clean Air Act Approval and Promulgation of State Implementation

Plans; Vermont: PM10 Prevention of Significant Deterioration Increments

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing full approval of a State Implementation Plan

(SIP) revision submitted by the State of Vermont, which replaces the

total suspended particulate (TSP) prevention of significant (PSD)

increments with increments for PM10 (particulate matter with an

aerodynamic diameter smaller than or equal to a nominal 10

micrometers). This action is being taken under the Clean Air Act. In

the Final Rules Section of this Federal Register, EPA is approving the

Vermont's SIP revision as a 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 proposed rule. If EPA does receive

adverse comments, the direct final rule will be withdrawn and all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 proposal. Any parties interested in commenting on this

proposal should do so at this time.

DATES: Comments must be received on or before September 3, 1997.

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

Office of Ecosystem Protection, EPA-Region 1, JFK Federal Bldg (CAA),

Boston, MA 02203. Copies of Vermont's submittal and EPA's technical

support document are available for public inspection by appointment

during normal business hours at the following locations: Office of

Ecosystem Protection, EPA-Region 1, One Congress Street, 11th floor,

Boston, MA 02203; Air Pollution Control Division, Agency of Natural

05676; and Air and Radiation Docket and Information Center, 401 M
