Attachment B Iron and Steel Manufacturing Wastewater Standards The United States Environmental Protection Agency (U.S. EPA) has established numerical "effluent limitations" for several segments of the iron and steel manufacturing industry. Numerica1limits have been established for facilities that discharge treated effluent directly to a receiving water. There are also limits for facilities that discharge wastewater to a municipal treatment plant. The limitations established by U.S. EPA arc based on an evaluation of the "best available treatment (BAT)" for the types of wastes generated by the iron and steel manufacturing industry. U.S. EPA gathered data on the performance of well operated treatment systems, statistically evaluated these data, and developed effluent limitations reflective of treatment system performance. Limitations are published in "production-based" format; thus, each facility will receive unique mass or concentration-based limits depending on the production rate at the facility. Unique limitations are developed for both a "daily maximum" (average over a calendar day), and a "monthly average" (average over a calendar month). Selected U.S. EPA iron and steel manufacturing emuent limitations that would apply to a facility conducting steelmaking by electric arc furnacc, continuous casting, and hot rolling are provided in Table B-1 below. Facility specific limits arc imposed and enforced by the government through discharge permits. In addition, municipal governments may establish more stringent numerical limitations than the U.S. EPA limitations for industries that discharge to the municipal sewer system. These limitations may be based on the treatment capacity of the municipal treatment plant or on the technology available to industrial user to control its discharge. In the United States permits issuct.l to the industries arc enforceable by the Federal, State and local governments and private citizens. Discharge standards that apply to iron and stcel facilitics in Turkey, Japan, and Germany arc presented in Tables 0-2, B-3, and 0-4, respectively. IIII II. ,.,.-~--
