E7-10238. Revisions to the California State Implementation Plan, San Joaquin Valley Unified Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD) portion of the California State Implementation Plan (SIP). These revisions concern Oxides of Nitrogen (NO_X) emissions from Boilers, Steam Generators and Process Heaters (2.0 MMBtu/hr to 5.0 MMBtu/hr, and 0.075 MMBtu/hr to 2.0 MMBtu/hr); Dryers, Dehydrators, and Ovens; Natural Gas-Fired, Fan-Type Residential Central Furnaces; and Solid Fuel Fired Boilers, Steam Generators and Process Heaters. We are proposing to approve local rules to regulate these emission sources under the Clean Air Act as amended in 1990 (CAA or the Act).

Any comments on this proposal must arrive by June 29, 2007.

SUPPLEMENTARY INFORMATION:

This proposal addresses the following local rules: SJVUAPCD Rules 4307, 4308, 4309, 4352, and 4905. In the Rules and Regulations 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. 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 30, 2007.

Laura Yoshii,

Acting Regional Administrator, Region IX.
