PART 422_PHOSPHATE MANUFACTURING POINT SOURCE CATEGORY--Table of Contents

 

               Subpart B_Phosphorus Consuming Subcategory

 

Sec.  422.20  Applicability; description of the phosphorus consuming 

subcategory.





    The provisions of this subpart are applicable to discharges of 

pollutants resulting from the manufacture of phosphoric acid, phosphorus 

pentoxide, phosphorus pentasulfide, phosphorus trichloride, and 

phosphorus oxychloride directly from elemental phosphorus. The 

production of phosphorus trichloride and phosphorus oxychloride creates 

waste water pollutants not completely amenable to the procedures 

utilized for best practicable control technology currently available. 

The standards set for phosphorus trichloride manufacture and phosphorus 

oxychloride manufacture, accordingly, must differ from the rest of the 

subcategory at this level of treatment.
