(A) Discharges from each separate discharge of a user, as measured under the provisions of this chapter, shall not contain in excess of the following concentrations based upon a 24-hour composite sample. Multiple industrial wastewater discharges from a permitted facility may be combined in a flow weighted manner to determine compliance with the following limitations for a 24-hour composite sample.
(B) Discharges from Amoco’s Wood River Facility, as measured under the provisions of this section, shall not contain in excess of the following concentrations based on a 24-hour composite sample. A portion of the discharge from Amoco Petroleum Additives Company is subject to National Categorical Pretreatment Standards for Organic Chemicals, Plastics, and Synthetic Fibers (OCPSF), discharge limitations of which are located in 40 C.F.R. part 414. The following limitations apply to Amoco’s Wood River Facility’s dedicated piping to the influent of the Parshall Flume before entering the process pump station.
