The reports provides guidance for each step in the water quality-based toxics control process from screening to compliance monitoring; Section 1 discusses the advantages and disadvantages of two approaches to toxics control: toxicity testing and chemical specific assessment; Section 2, Water Quality Criteria and Standards, contains a brief discussion of water quality standards and the derivation of ambient criteria to attain and maintain standards; Section 3, Effluent Characterization, describes procedures that provide the data needed to make decisions regarding toxic impact. A two-tiered assessment approach is recommended; Section 4, Human Health Hazard Assessment, describes procedures for assessing potential human health hazards associated with effluents; Section 5, Exposure assessment, describes procedures for estimating exposure to toxicants and calculating effluent requirements based on ambient criteria and exposure; Section 6, Permit Requirements, describes methods to develop water quality-based NPDES permits.
