Environment (Waste Management)

SB 621 exempts municipal waste incinerators already regulated under federal rules (40 C.F.R. Part 60 Subpart Eb) and Oklahoma's Department of Environmental Quality from future state regulations covering specific waste types, including biomedical, hospital, commercial, and industrial waste incineration. The bill directly affects waste management facilities operating under existing federal and state oversight. It prevents the Department of Environmental Quality from imposing additional state rules on these facilities for the listed waste streams. The bill was introduced as an emergency measure to take immediate effect upon passage.
