          - 40 CFR Part 52 
          - [CA 031-0174b; FRL-6580-4] 

# AGENCY:

Environmental Protection Agency (EPA). 

# ACTION:

Proposed rule. 

# SUMMARY:

EPA is approving revisions to the California State Implementation Plan. The revisions concern rules from the following: Lake County Air Quality Management District (LCAQMD) and San Joaquin Valley Unified Air Pollution Control District (SJVUAPCD). The rules control particulate matter (PM) emissions from open burning or processes identified by a weight rate throughput. 

                        The intended effect of this action is to regulate emissions of PM in accordance with the requirements of the Clean Air Act, as amended in 1990 (CAA or the Act). In the Final Rules section of this                         **Federal Register**                        , the EPA is approving the state's SIP revision as a direct final rule without prior proposal because the Agency views this as a noncontroversial revision and anticipates no adverse comments. A detailed rationale for this approval is set forth in the direct final rule. If no relevant adverse comments are received, no further activity is contemplated in relation to this rule. If EPA receives relevant adverse comments, the direct final rule will not take effect 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 on this rule. Any parties interested in commenting on this rule should do so at this time.
