## Abstract

Previously, the ozone monitoring season in Region 4 was twelve months in Florida; March--November in Georgia, Alabama, and Mississippi; and April--October in North Carolina, South Carolina, Tennessee, and Kentucky. Based on review of ozone monitoring data, Region 4 has determined that the appropriate ozone monitoring ozone season should be April 1-October 31 for all Region 4 states except Florida. Florida will continue to have a twelve month monitoring season.
