03-7641. Approval and Promulgation of Air Quality Implementation Plans; Pennsylvania; NOX

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA proposes to approve the State Implementation Plan (SIP) revision submitted by the Commonwealth of Pennsylvania to establish and require reasonably available control technology (RACT) for five major sources of nitrogen oxides (NO_X) located in Pennsylvania. In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittal as a direct final rule without prior proposal because the Agency views this as a noncontroversial submittal 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, 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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.

DATES:

Comments must be received in writing by May 1, 2003.

ADDRESSES:

Written comments should be addressed to Walter K. Wilkie, Deputy Branch Chief, Air Quality Planning & Information Services Branch, Air Protection Division, Mailcode 3AP21, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103. Copies of the documents relevant to this action are available for public inspection during normal business hours at the Air Protection Division, U.S. Environmental Protection Agency, Region III, 1650 Arch Street, Philadelphia, Pennsylvania 19103; and the Pennsylvania Department of Environmental Resources, Bureau of Air Quality Control, P.O.

SUPPLEMENTARY INFORMATION:

For further information, please see the information provided in the direct final action, Pennsylvania's Approval of NO_X RACT Determinations for Five Individual Sources, that is located in the “Rules and Regulations” section of this Federal Register publication. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of this rule and if that provision 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.
