01-20783. Approval and Promulgation of Air Quality Implementation Plans; Maryland; Administrative Revisions of General Provisions Related to Definitions of Terms and Ambient Air Quality Standards

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing approval of revisions to the Maryland State Implementation Plan (SIP). In this action, EPA is proposing approval of revisions which reorganize the structure of the general administrative provisions describing definitions of terms used throughout Maryland's air pollution control regulations, amend the definition of the term “source;” and reorganize the provisions governing ambient air quality standards. EPA is approving these revisions in accordance with the requirements of the Clean Air Act. In the Final Rules section of this Federal Register, EPA is approving the State's SIP submittals as a direct final rule without prior proposal because the Agency views them as noncontroversial submittals 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 If EPA receives adverse comments, the direct final rule will be withdrawn and all public comments received will be addressed in a subsequent final rule based on this proposed rule.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. Please note that if EPA receives adverse comment on an amendment, paragraph, or section of the direct final 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.

DATES:

Comments must be received in writing by September 19, 2001.

ADDRESSES:

Written comments should be addressed to Harold A. Frankford, Office of Air Programs, Mailcode 3AP20, 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 Maryland Department of the Environment, 2500 Broening Highway, Baltimore, Maryland, 21224.
