§415.640   Applicability; description of the cadmium pigments and salts production subcategory.

The provisions of this subpart are applicable to discharges and to the introduction of pollutants into treatment works which are publicly owned resulting from the production of cadmium pigments and salts including cadmium chloride, cadmium nitrate, and cadmium sulfate salts.

§415.641   Specialized definitions.

For the purpose of this subpart:

(a) Except as provided below, the general definitions, abbreviations, and methods of analysis set forth in part 401 of this chapter shall apply to this subpart.

(b) The term product shall mean cadmium pigment or cadmium salt.

(c) The term cadmium shall mean the total cadmium present in the process wastewater stream exiting the wastewater treatment system.

(d) The term selenium shall mean the total selenium present in the process wastewater stream exiting the wastewater treatment system.

(e) The term zinc shall mean the total zinc present in the process wastewater stream exiting the wastewater treatment system.
