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.
