Pages 423-558.  ENVIRONMENTAL PROTECTION AGENCY 40 CFR Parts 413, 433, 438, 463, 464, 467, and 471 Effluent Limitations Guidelines, Pretreatment Standards, and New Source Performance Standards for the Metal Products and Machinery Point Source Category; Proposed Rule AGENCY: Environmental Protection Agency (EPA). ACTION: Proposed rule. ----------------------------------------------------------------------- SUMMARY: This proposal represents the Agency's second look at Clean Water Act national effluent limitations guidelines and pretreatment standards for wastewater discharges from metal products and machinery facilities. EPA initially proposed effluent limitations guidelines and pretreatment standards for a portion of this category on May 30, 1995 (60 FR 28210). This proposal completely replaces the 1995 proposal. Today's proposed regulation would establish technology-based effluent limitations guidelines and pretreatment standards for wastewater discharges associated with the operation of new and existing metal products and machinery facilities. The metal products and machinery industry includes facilities that manufacture, rebuild, or maintain metal products, parts, or machines.     EPA estimates that compliance with this regulation will reduce the discharge of conventional pollutants by at least 115 million pounds per year, priority pollutants by 12 million pounds per year, and nonconventional metal and organic pollutants by 43 million pounds per year for an estimated compliance cost of $1.98 billion (pre-tax, 1999$) annually. EPA estimates that the annual benefits of the proposal rangefrom $0.4 billion to $1.1 billion. In addition, this proposal solicits comment on new methodologies for expanding the analysis to include additional categories of recreational benefits.
