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 sodium chlorate.
(b) The term product shall mean sodium chlorate.
(c) The term chromium shall mean the total chromium present in the process wastewater stream exiting the wastewater treatment system.
(d) The term chlorine shall mean the total residual chlorine present in the process wastewater stream exiting the wastewater treatment system.
(e) The term antimony shall mean the total antimony present in the process wastewater stream exiting the wastewater treatment system.
(a) Except as provided in 40 CFR 125.30 through 125.32, any existing point source subject to this subpart must achieve the following effluent limitations representing the degree of effluent reduction attainable by the application of the best practicable control technology currently available (BPT).
