Approval and Promulgation of State Implementation Plans; Indiana; Rules To Control Particulate Matter and Carbon Monoxide From Incinerators

On October 30, 2002, and January 10, 2003, Indiana submitted a plan to EPA which contained revised and updated rules to control emissions of particulate matter (PM) from incinerators and carbon monoxide (CO) from incinerators and other industrial categories. The rule changes accomplish several objectives. First, they re-adopt useful elements of regulations which were scheduled to expire because of "sunset requirements" under the Indiana Code. In addition, they incorporate by reference a number of applicable EPA rules affecting certain types of incineration units and clarify which limits pertain to other types of units. The revised requirements will apply to those incinerators in the State where Federal rules or guidelines do not apply. Finally, Indiana has eliminated references to language which is outdated and unclear. EPA is taking final action to approve this State plan revision.
