Approval and Promulgation of Air Quality Implementation Plans; Illinois; Leisure Properties LLC/D/B/A Crownline Boats; Adjusted Standard

EPA is approving into the Illinois State Implementation Plan (SIP) an adjusted standard for Leisure Properties LLC/D/B/A Crownline Boats (Crownline) at its West Frankfort, Illinois facility. On June 10, 2011, the Illinois Environmental Protection Agency (IEPA) submitted to EPA for approval an adjustment to the general rule, Use of Organic Material Rule, commonly known as the eight pound per hour (8 lb/hr) rule, as it applies to emissions of volatile organic matter (VOM) from Crownline's manufacturing facility. The adjusted standard relieves Crownline from being subject to the general rule for VOM emissions from its West Frankfort facility. EPA is approving this SIP revision because it will not interfere with attainment or maintenance of the ozone National Ambient Air Quality Standard (NAAQS).
