The rule proposed to be repealed lists the air emissions test methods to be used where a compliance test is required by a department air pollution rule or air permit. This list of test methods in Rule 62-297.401, F.A.C., is no longer necessary because the required test method for a compliance test is now prescribed in each rule that requires a compliance test to be performed. The state air emissions opacity test method “DEP Method 9” is being repealed in order for businesses to be able to rely solely on a comparable federal air emissions opacity test method, “EPA Method 9”, so that businesses will not be subject to both state and federal opacity test methods.
