CFR Citation: 40 CFR Part 52

EPA ID: [EPA-R09-OAR-2006-0186, FRL-8569-7]

NOTICE: PROPOSED RULES

ACTION: California State Implementation Plan; Revision:

DOCUMENT ACTION: Proposed rule.

SUBJECT CATEGORY: Revisions to the California State Implementation Plan, Northern Sierra Air Quality Management District, Including the Nevada County Air Pollution Control District Portion, Plumas County Air Pollution Control District Portion, and Sierra County Air Pollution Control District Portion

DATES: Any comments on this proposal must arrive by August 8, 2008.

DOCUMENT SUMMARY: EPA is proposing to approve revisions to the Northern Sierra Air Quality Management District (NSAQMD) portion of the California State Implementation Plan (SIP), including the Nevada County Air Pollution Control District (NCAPCD) portion, Plumas County Air Pollution Control District (PCAPCD) portion, and Sierra County Air Pollution Control District (PCAPCD) portion of the SIP. These revisions concern the permitting of air pollution sources. We are approving and removing local rules under authority of the Clean Air Act as amended in 1990 (CAA or the Act).

SUMMARY: Sierra Air Quality Management District, et al.,

SUPPLEMENTAL INFORMATION

This proposal addresses the approval of NSAQMD Rules 501, 505, 510, 511, 512, 513, 515, and 517 into the SIP and the removal of eight NCAPCD, two PCAPCD, and four SCAPCD permitting rules from the SIP. In the Rules section of this Federal Register, we are approving revisions in these local rules in a direct final action without prior proposal because we believe these SIP revisions are not controversial. If we receive adverse comments, however, we will publish a timely withdrawal of the direct final rule and address the comments in subsequent action based on this proposed rule.

Please note that if we receive adverse comment on an amendment, paragraph, or section of this rule and if that provision may be severed from the remainder of the rule, we may adopt as final those provisions of the rule that are not the subject of an adverse comment.

We do not plan to open a second comment period, so anyone interested in commenting should do so at this time. If we do not receive adverse comments, no further activity is planned. For further information, please see the direct final action.

Dated: April 16, 2008.

Acting Regional Administrator, Region IX.
