Michigan Administrative Code › Department - Environmental Quality › Air Quality Division › Part 2 - AIR USE APPROVAL › Section R. 336.1205 - Permit to install; approval

Current through Vol. 24-12, July 15, 2024
Rule 205.
(1) The
				department shall not approve a permit to install for a stationary source,
				process, or process equipment that meets the definition of a major stationary
				source or major modification under any part of these rules unless the
				requirements specified in subdivisions (a) and (b) of this subrule have been
				met. In addition, except as provided in subrule (3) of this rule, the
				department shall not approve a permit to install that includes limitations
				which restrict the potential to emit from a stationary source, process, or
				process equipment to a quantity below that which would constitute a major
				source or major modification under any part of these rules unless both of the
				following requirements have been met:
(a) The
				permit to install contains emission limits that are enforceable as a practical
				matter. An emission limit restricts the amount of an air contaminant that may
				be emitted over some time period. The time period shall be set in accordance
				with the applicable requirements and, unless a different time period is
				provided by the applicable requirement, should generally not be more than 1
				month, unless a longer time period is approved by the department. A longer time
				period may be used if it is a rolling time period, but shall not be more than
				an annual time period rolled on a monthly basis. If the emission limit does not
				reflect the maximum emissions of the process or process equipment operating at
				full design capacity without air pollution control equipment, then the permit
				shall contain 1of the following:
(i) A
				production limit that restricts the amount of final product that may be
				produced over the same time period used in the emission limit and that comports
				with the true design and intended operation of the process or process
				equipment.
(ii) An operational
				limit that restricts the way the process or process equipment is operated and
				that comports with the true design and intended operation of the process or
				process equipment. An operational limit may include conditions specifying any
				of the following:
(A) The installation,
				operation, and maintenance of air pollution control equipment.
(B) The hours of operation of the stationary
				source, process, or process equipment, if the hours are less than
				continuous.
(C) The amount or type
				of raw materials used by the stationary source, process, or process
				equipment.
(D) The amount or type
				of fuel combusted by the stationary source, process, or process
				equipment.
(E) The installation,
				operation, and maintenance of a continuous gas flow meter and a continuous
				emission monitor for the air contaminant for which an enforceable emission
				limit is required.
(iii)
				For volatile organic compound surface coating operations where an add-on
				control is not employed, an emission or usage limit coupled with a requirement
				to calculate or demonstrate daily compliance.
