b. Visible emissions shall not exceed 20% opacity.
In addition, the following requirements of Regulation No. 6, Part A, Subpart A, General Provisions, apply.
a. At all tunes, including periods of start-up, shutdown, and malfunction, the facility and control
equipment shall, to the extent practicable, be maintained and operated in a manner consistent with
good air pollution control practices for minimizing emissions. Determination of whether or not
acceptable operating and maintenance procedures are being used will be based on information
available to the Division, .which may include, but is not limited to, monitoring results, opacity
observations, review of operating and maintenance procedures, and inspection of the source.
(Reference: Regulation 6, Part A. General Provisions from 40CFR60.11
b. No article, machine, equipment or process shall be used to conceal an emission which would
otherwise constitute a violation of an applicable standard. Such concealment includes, but is not

shall not exceed the major stationary source threshold until compliance with Regulation 3.B.IV.D.2. has
been achieved.
12. Operating Permit (OP) requirements shall apply to this source at any such time that this source becomes
