Description of Facilities/Processes Claimed in this Registration and Exemptions Claimed: The company claims that  all Requirements of Exemption 118 are met.             
Sources, Emissions and Control Summary: This review is being conducted under standard exemption rules only.  The company claims that the liquid (analysis attached) should have emissions of approximately zero.  The liquid is mixed with sodium sulfite to precipitate metals.  The liquids will have any emissions vented through a scrubber.  The only emissions based upon the analysis would be from dissolved low concentrations of ammonia and bromine.  Any very small emissions of ammonia or bromine that would volatilize out of the liquid will be soluble and very scrubbable.  Emissions should be approximately zero.  The distance to the nearest receptor is estimated at 600'.  The emissions of ammonia and bromine would be under a limit of  (E = 18/65 = 0.28 lbs/hr) and  (E = 0.7/65 = 0.011 lbs/hr).
