122. Surface coating operation utilizing powder coating materials with the powder applied by an electrostatic powder spray gun or an electrostatic fluidized bed.

123. Woodworking shops with an internal sawdust collection system that meets the following conditions:

  1. The collection system exhausts to a fabric filter with air cleaning and a filtering velocity no greater than 7.0 ft/min, or automatic sequenced mechanical cleaning and a filtering velocity no greater than 5.0 ft/min.
  2. Disposal of collected material is accomplished in a manner which will prevent the material form becoming airborne.
  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.
  2. The new and/or increased emissions including fugitive of all air contaminants will not exceed 3 pounds per hour, 50 pounds per day and 5 tons per year.
  3. The emissions from the facility will not cause or contribute to a condition of "air pollution" as defined in Section 1.03 of the Texas Clean Air Act.
  4. There will be no visible fugitive emissions from the facility.

  3. The cover is closed at all times except when processing work loads into and out of the degreaser.
  4. The unit is equipped with a properly sized refrigerated chiller or the unit has a freeboard ratio (the distance from top of the vapor level to the top edge of the degreasing tank divided by the degreaser width) equal to or greater than 0.75.
  5. Waste solvent is stored only in covered containers.
  6. Chlorinated solvents total make-up use is limited to 55 gallons per month (Gross purchased minus waste disposal).
  7. The unit must be registered with Form PI-7.

126. Portable Pipe Reactor Process Liquid Fertilizer Blending Plants that operate according to the following conditions:

  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.
  4. Emissions from the facility shall not cause or contribute to a condition of air pollution as defined in Section 1.03 of the Texas Clean Air Act.

127. Any facility where animals or poultry are slaughtered and prepared for human consumption when waste products such as blood, offal and feathers are stored in such a manner as to prevent the creation of a nuisance condition and these waste products are removed from the premises daily or stored under refrigeration until removed.
