Rule 912.
(1) The
				owner or operator of a source, process, or process equipment shall, to the
				extent reasonably possible, operate a source, process, or process equipment in
				a manner consistent with good air pollution control practices for minimizing
				emissions during periods of abnormal conditions, start-up, shutdown, and
				malfunctions. A source, process, or process equipment that complies with all
				applicable emission standards and limitations during periods of abnormal
				conditions, start-up, shutdown, and malfunction shall be presumed to have been
				operated in a manner consistent with good air pollution control practices for
				minimizing emissions.
(2) The owner
				or operator of a source, process, or process equipment shall provide notice of
				an abnormal condition, start-up, shutdown, or a malfunction that results in
				emissions of a hazardous air pollutant which continue for more than 1 hour in
				excess of any applicable standard or limitation established by the clean air
				act or the emissions of a toxic air contaminant which continue for more than 1
				hour in excess of an emission standard established by a rule promulgated under
				the air pollution act or an emission limitation specified in a permit issued or
				order entered under the air pollution act.
(3) The owner or operator of a source,
				process, or process equipment shall provide notice and a written report of an
				abnormal condition, start-up, shutdown, or a malfunction that results in
				emissions of any air contaminant continuing for more than 2 hours in excess of
				a standard or limitation established by any applicable requirement.
(4) The notices required by this rule shall
				be provided to the department as soon as reasonably possible, but not later
				than 2 business days after the start-up or shutdown or after discovery of the
				abnormal conditions or malfunction. Notice shall be by any reasonable means,
				including electronic, telephonic, or oral communication.
(5) The written reports required under this
				rule shall be submitted within 10 days after the start-up or shutdown occurred,
				within 10 days after the abnormal conditions or malfunction has been corrected,
				or within 30 days of discovery of the abnormal conditions or malfunction,
				whichever is first. The written reports shall include all of the following
				information:
(a) The time and date, the
				probable causes or reasons for, and the duration of the abnormal conditions,
				start-up, shutdown, or malfunction.
(b) An identification of the source, process,
				or process equipment that experienced abnormal conditions, was started up or
				shut down, or which malfunctioned and all other affected process or process
				equipment that have emissions in excess of an applicable requirement, including
				a description of the type and, where known or where it is reasonably possible
				to estimate, the quantity or magnitude of emissions in excess of applicable
				requirements.
(c) Information
				describing the measures taken and air pollution control practices followed to
				minimize emissions.
(d) For
				abnormal conditions and malfunctions, the report shall also include a summary
				of the actions taken to correct and to prevent a reoccurrence of the abnormal
				conditions or malfunction and the time taken to correct the
				malfunction.
