[R01-OAR-2004-ME-0001; A-1-FRL-7625-4]


Approval and Promulgation of Air Quality Implementation Plans; 
Maine; Approval of State Implementation Plan Revision to PM10 PSD 
Increments

AGENCY: Environmental Protection Agency (EPA).

ACTION: Proposed rule.

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

SUMMARY: EPA is proposing to approve a State Implementation Plan (SIP) 
revision submitted by the State of Maine. This revision establishes 
maximum allowable increases in particulate matter concentration for the 
prevention of significant deterioration (PSD) program, where 
particulate matter is measured as particulates with a mean aerodynamic 
diameter of 10 microns or less (``PM10''), rather than as total 
suspended particulates (TSP).

DATES: Written comments must be received on or before April 21, 2004.

ADDRESSES: Comments may be mailed to Dan Brown, Acting Unit Manager, 
Air Permits, Toxics, and Indoor Air Programs, Office of Ecosystems 
Protection (mail code CAP), U.S. Environmental Protection Agency, EPA 
New England Regional Office, One Congress Street, Suite 1100, Boston, 
MA 02114-2023. Comments may also be submitted electronically or through 
hand delivery/courier; please follow the detailed instructions in part 
(I)(B)(1)(i) through (iv) of the SUPPLEMENTARY INFORMATION section of 
the direct final rule which is located in the rules section of this 
Federal Register.

FOR FURTHER INFORMATION CONTACT: Ian D. Cohen, Air Permits, Toxics, and 
Indoor Air Programs Unit, U.S. Environmental Protection Agency, EPA New 
England Regional Office, One Congress Street, Suite 1100 (CAP), Boston, 
MA 02114-2023, (617) 918-1655, [email protected].

SUPPLEMENTARY INFORMATION: In the final rules section of this Federal 
Register, EPA is approving the State's SIP revision as a direct final 
rule without prior proposal because EPA views this rulemaking as 
noncontroversial 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 action rule, no 
further activity is contemplated. 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direct final rule will be withdrawn and all public comments received 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. Any parties 
interested in commenting on this action should do so at this time. If 
EPA receives adverse comments on a section, paragraph, or other portion 
of this rule that may be severed from the remainder of the rule, EPA 
may adopt as final those provisions of the rule that are not the 
subject of an adverse comment.
    For additional information, see the direct final rule located in 
the final rules section of this Federal Register.

    Dated: February 5, 2004.

Regional Administrator, EPA New England.
