Subp. 1a.Applicability for owners and operators of facilities not regulated as hazardous waste facilities by federal regulation.Owners and operators of hazardous waste facilities that are not federally regulated as hazardous waste facilities that are, for example, regulated as facilities by state rule only, are subject to the applicable requirements of parts 7045.0552 to 7045.0649 on the effective date of any rules that make the facility subject to regulation. The facility shall submit a Part B application for a hazardous waste facility permit to the commissioner within one year of the effective date of any rules that first make the facility subject to the requirement to obtain a hazardous waste facility permit.
Subp. 2.Existing hazardous waste facilities.For facilities subject to the provisions of Code of Federal Regulations, title 40, part 265, as amended, an "existing hazardous waste facility" or "existing facility" means a facility which was in operation or for which construction commenced on or before November 19, 1980. For all other facilities, an "existing hazardous waste facility" or "existing facility" means a facility which was in operation on or before July 16, 1984, or for which construction commenced on or before July 16, 1984.
