Revisions to the California State Implementation Plan, Imperial County Air Pollution Control District

AGENCY:

Environmental Protection Agency (EPA).

ACTION:

Proposed rule.

SUMMARY:

EPA is proposing to approve revisions to the Imperial County Air Pollution Control District (ICAPCD) portion of the California State Implementation Plan (SIP). These revisions concern the emission of particulate matter (PM-10) and sulfur compounds into the atmosphere from industrial processes. We are proposing to approve local rules that administer regulations and regulate emission sources under the Clean Air Act as amended (CAA or the Act).

DATES:

Any comments on this proposal must arrive by December 16, 2004.

ADDRESSES:

SUPPLEMENTARY INFORMATION:

This proposal addresses the following local rules: ICAPCD Rules 403 and 405. 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.
