03-25801. Revisions to the California State Implementation Plan, El Dorado County Air Pollution Control District and Santa Barbara County Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the El Dorado County Air Pollution Control District (EDCAPCD) and Santa Barbara County Air Pollution Control District (SBCAPCD) portions of the California State Implementation Plan (SIP). These revisions concern nitrogen oxide (NO_X) emissions from biomass boilers and from large water heaters and small boilers. We are proposing to approve a local rule under the Clean Air Act as amended in 1990 (CAA or the Act).

DATES:

Any comments on this proposal must arrive by November 13, 2003.

SUPPLEMENTARY INFORMATION:

This proposal addresses the approval of local EDCAPCD Rule 232 and SBCAPCD Rule 360. In the Rules section of this Federal Register, we are approving 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. 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: September 3, 2003.

Regional Administrator, Region IX.
