Approval and Promulgation of Implementation Plans; California State Implementation Plan Revision, South Coast Air Quality Management District

EPA is finalizing disapproval of Rule 1623 of the South Coast Air Quality Management District (SCAQMD) which has been submitted as a revision to the State Implementation Plan (SIP). EPA proposed disapproval of this revision in the Federal Register on January 18, 2000. Rule 1623, Credits for Lawn and Garden Equipment, provides a mechanism for issuing mobile source emission reduction credits (MSERCs) to entities who sell or replace old engine-powdered lawn and garden equipment with new low- or zero-emission lawn and garden equipment. EPA is finalizing disapproval under CAA provisions regarding EPA action on SIP submittals and general rulemaking authority because this revision is not consistent with applicable CAA requirements.
