252:100-37-35.  Waste gas disposal

     (a)  Ethylene manufacturing emissions.  No owner or operator shall build or install any ethylene manufacturing plant unless the waste-gas stream under normal operating conditions is properly burned at 1,300 degrees F for 0.3 seconds or greater in a direct-flame afterburner equipped with an indicating pyrometer that is positioned in the working area for the operator's ready monitoring or an equally effective catalytic vapor incinerator also with pyrometer.  Proper burning of the waste-gas stream is defined as reduction by 98 percent of the ethylene emissions originally present in the waste-gas stream.

     (b)  Vapor blowdown.  Except where inconsistent with the "Minimum Federal Safety Standards for the Transportation of Natural and Other Gas by Pipeline" or any State of Oklahoma regulatory agency, no owner or operator shall allow VOC gases to be emitted from a vapor recovery blowdown system unless these gases are burned by smokeless flares or an equally effective control device as approved by the Division Director.


252:100-37-36.  Fuel-burning and refuse-burning equipment

     All fuel-burning or refuse-burning equipment shall be operated to minimize emissions of VOC.  Among other things, such operation shall assure, based on manufacturer's data and good engineering practice, that the equipment is not overloaded; that it is properly cleaned, operated, and maintained; and that temperature and available air are sufficient to provide essentially complete combustion.


252:100-37-37.  Effluent water separators

     A single-compartment or multiple-compartment VOC/water separator that receives effluent water containing 200 gal/d (760 l/d) or more of any VOC from any equipment processing, refining, treating, storing or handling VOCs shall comply with one of the following sets of conditions.
          (1)  The container totally encloses the liquid contents and all openings are sealed.  All gauging and sampling devices shall be gas-tight except when gauging or sampling is taking place.  The oil removal devices shall be gas-tight except when manual skimming, inspection and/or repair is in progress.
          (2)  The container is equipped with an external floating roof that consists of a pontoon type or double-deck type cover, or a fixed roof with an  internal-floating cover.  The cover shall rest on the surface of the contents and be equipped with a closure seal, or seals, to close the space between the cover edge and container wall.  All gauging and sampling devices shall be gas-tight except when gauging or sampling is taking place.  The oil removal devices shall be gas-tight except when manual skimming, inspection and/or repair is in progress.
          (3)  The container is equipped with a vapor-recovery system that consists of a vapor-gathering system capable of collecting the VOC vapors and gases discharged and a vapor-disposal system capable of processing such vapors and gases to prevent their emission to the atmosphere.  All tank gauging and sampling devices shall be gas-tight except when gauging or sampling is taking place.  The VOC removal devices shall be gas-tight except when manual skimming, inspection and/or repair is in progress.
          (4)  The container is approved prior to use by the Division Director and is equipped with controls that have efficiencies equal to the controls listed in 252:100-37-37(1) through (3).


252:100-37-38.  Pumps and compressors

     (a)  Any pump or compressor handling VOCs shall meet the following conditions.
          (1)  Rotating type pumps and compressors are equipped with mechanical seals or other equipment of equal efficiency.
          (2)  Reciprocating type pumps and compressors are equipped with packing glands.
          (3)  Emissions from the drain recovery system do not exceed 2 in.³ of liquid VOC in any 15-minute period per pump or compressor at standard conditions.

     (b)  Pumps and compressors subject to the standards for pumps and compressors contained in 40 CFR 60 Subparts VV, GGG, or KKK are exempt from 252:100-37-38.
