III. PROCESS/OPERATIONAL RESTRICTION(S)

The provisions of Rule 290 apply to each emission unit that is operating pursuant to Rule 290. (R 336.1290)

The following requirements apply to emission units installed on or after December 20, 2016, utilizing control equipment:

An air cleaning device for volatile organic compounds shall be installed, maintained, and operated in accordance with the manufacturer’s specifications. Examples include the following: (R 336.1290(2)(b)(i),
