Text: 230 Union Carbide argues that high influent BODS concentrations at its Taft, Louisiana, plant preclude effective treatment by the model BPT technology. Union Carbide thus contends that the EPA has neither costed nor identified any BPT technology which will enable plants with high-BOD influent to comply with BPT. The EPA costed the addition of a biological treatment unit followed by a secondary clarifier to Taft's existing treatment system. 174 This additional treatment system will remove almost four million pounds of conventional pollutants at an annualized cost of $1,242,200. 175 231 The EPA reasonably concluded that the Taft plant was not so fundamentally different from the industry as a whole as to warrant exclusion from the rule simply because the Taft plant had the highest levels of BODS influent in the data base used to develop the limits. The EPA has concluded reasonably that the limitations are both achievable and practicable for the Taft plant.
