                TITLE 40-PROTECTION OF ENVIRONMENT
 
      CHAPTER I-ENVIRONMENTAL PROTECTION AGENCY (CONTINUED)
 
PART 414-ORGANIC CHEMICALS, PLASTICS, AND SYNTHETIC FIBERS--Table of Contents
 
  Subpart I-Direct Discharge Point Sources That Use End-of-Pipe 
                          Biological Treatment
 
Sec. 414.91  Toxic pollutant effluent limitations and standards for direct discharge point sources that use end-of-pipe biological treatment.

    (a) Any point source subject to this subpart must achieve discharges 
not exceeding the quantity (mass) determined by multiplying the process 
wastewater flow subject to this subpart times the concentrations in the 
following table.
    (b) In the case of chromium, copper, lead, nickel, zinc, and total 
cyanide, the discharge quantity (mass) shall be determined by 
multiplying the concentrations listed in the following table for these 
pollutants times the flow from metal-bearing waste streams for the 
metals and times the flow from cyanide bearing waste streams for total 
cyanide. The metal-bearing waste streams and cyanide-bearing waste 
streams are defined as those waste streams listed in Appendix A of this 
part, plus any additional OCPSF process wastewater streams identified by 
the permitting authority on a case-by-case basis as metal or cyanide 
bearing based upon a determination that such streams contain significant 
amounts of the pollutants identified above. Any such streams designated 
as metal or cyanide bearing must be treated independently of other metal 
or cyanide bearing waste streams unless the permitting authority 
determines that the combination of such streams, prior to treatment, 
with the Appendix A waste streams will result in substantial reduction 
of these pollutants. This determination must be based upon a review of 
relevant engineering, production, and sampling and analysis information.
