Partial Withdrawal of Direct Final Rule Revising the California State Implementation Plan, San Joaquin Valley Air Pollution Control District

On May 30, 2007 (72 FR 29886), EPA published a direct final approval of revisions to the California State Implementation Plan (SIP). These revisions concerned San Joaquin Valley Air Pollution Control District (SJVAPCD) Rule 4307, Boilers, Steam Generators and Process Heaters--2.0 MMBtu/hr to 5.0 MMBtu/hr; Rule 4308, Boilers, Steam Generators and Process Heaters--0.075 MMBtu/hr to 2.0 MMBtu/hr; Rule 4309, Dryers, Dehydrators, and Ovens; Rule 4352, Solid Fuel Fired Boilers, Steam Generators and Process Heaters; and Rule 4905, Natural Gas-Fired, Fan-Type Residential Central Furnaces. The direct final action was published without prior proposal because EPA anticipated no adverse comment. The direct final rule stated that if adverse comments were received by June 29, 2007, EPA would publish a timely withdrawal in the Federal Register. EPA received timely adverse comments. Consequently, with this revision we are withdrawing the direct final approval of SJVAPCD Rule 4352. EPA will either address the comments in a subsequent final action based on the parallel proposal also published on May 30, 2007 (72 FR 29901), or repropose an alternative action. As stated in the parallel proposal, EPA will not institute a second comment period on a subsequent final action. The other rules approved in the May 30, 2007 direct final action, SJVAPCD Rules 4307, 4308, 4309, and 4905, are not affected by this partial withdrawal and are incorporated into the SIP as of the effective date of the May 30, 2007 direct final action.
