  3. There will be no visible fugitive emissions from the facility.

124. Facilities and equipment not otherwise addressed* by this list provided that:

  1. The emissions from the facility will not contain compounds listed as hazardous constituents in Federal Regulation 40 CFR 261, Appendix VIII.

  1. Written site approval is obtained from the Executive Director prior to construction or operation of the facility.
  2. All valves, piping, flanges, hoses and disconnects must be free of leaks.
  3. Opacity from any process vent shall not exceed 20% opacity except for those periods of start-up as defined in Regulation I, Rule 111.21.
