[Code of Federal Regulations] [Title 40, Volume 28] [Revised as of July 1, 2006] From the U.S. Government Printing Office via GPO Access [CITE: 40CFR414.91] [Page 235-236] 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 [[Page 236]] 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. ------------------------------------------------------------------------ Effluent limitations BAT and NSPS \1\ --------------------- Effluent characteristics Maximum Maximum for any for any monthly one day average ------------------------------------------------------------------------ Acenaphthene...................................... 59 22 Acenaphthylene.................................... 59 22 Acrylonitrile..................................... 242 96 Anthracene........................................ 59 22 Benzene........................................... 136 37 Benzo(a)anthracene................................ 59 22 3,4-Benzofluoranthene............................. 61 23 Benzo(k)fluoranthene.............................. 59 22 Benzo(a)pyrene.................................... 61 23 Bis(2-ethylhexyl) phthalate....................... 279 103 Carbon Tetrachloride.............................. 38 18 Chlorobenzene..................................... 28 15 Chloroethane...................................... 268 104 Chloroform........................................ 46 21 2-Chlorophenol.................................... 98 31 Chrysene.......................................... 59 22 Di-n-butyl phthalate.............................. 57 27 1,2-Dichlorobenzene............................... 163 77 1,3-Dichlorobenzene............................... 44 31 1,4-Dichlorobenzene............................... 28 15 1,1-Dichloroethane................................ 59 22 1,2-Dichloroethane................................ 211 68 1,1-Dichloroethylene.............................. 25 16 1,2-trans-Dichloroethylene........................ 54 21 2,4-Dichlorophenol................................ 112 39 1,2-Dichloropropane............................... 230 153 1,3-Dichloropropylene............................. 44 29 Diethyl phthalate................................. 203 81 2,4-Dimethylphenol................................ 36 18 Dimethyl phthalate................................ 47 19 4,6-Dinitro-o-cresol.............................. 277 78 2,4-Dinitrophenol................................. 123 71 2,4-Dinitrotoluene................................ 285 113 2,6-Dinitrotoluene................................ 641 255 Ethylbenzene...................................... 108 32 Fluoranthene...................................... 68 25 Fluorene.......................................... 59 22 Hexachlorobenzene................................. 28 15 Hexachlorobutadiene............................... 49 20 Hexachloroethane.................................. 54 21 Methyl Chloride................................... 190 86 Methylene Chloride................................ 89 40 Naphthalene....................................... 59 22 Nitrobenzene...................................... 68 27 2-Nitrophenol..................................... 69 41 4-Nitrophenol..................................... 124 72 Phenanthrene...................................... 59 22 Phenol............................................ 26 15 Pyrene............................................ 67 25 Tetrachloroethylene............................... 56 22 Toluene........................................... 80 26 Total Chromium.................................... 2,770 1,110 Total Copper...................................... 3,380 1,450 Total Cyanide..................................... 1,200 420 Total Lead........................................ 690 320 Total Nickel...................................... 3,980 1,690 Total Zinc \2\.................................... 2,610 1,050 1,2,4-Trichlorobenzene............................ 140 68 1,1,1-Trichloroethane............................. 54 21 1,1,2-Trichloroethane............................. 54 21 Trichloroethylene................................. 54 21 Vinyl Chloride.................................... 268 104 ------------------------------------------------------------------------ \1\ All units are micrograms per liter. \2\ Total Zinc for Rayon Fiber Manufacture that uses the viscose process and Acrylic Fiber Manufacture that uses the zinc chloride/solvent process is 6,796 [micro]g/l and 3,325 [micro]g/l for maximum for any one day and maximum for monthly average, respectively.
