STUDY OF PRETREATMENT OF TOXIC POLLUTANTS.

SEC. 519. STUDY OF PRETREATMENT OF TOXIC POLLUTANTS. (a) Study.—The Administrator shall study— (1) the adequacy of data on environmental impacts of toxic industrial pollutants discharged from publicly owned treatment works; (2) the extent to which secondary treatment at publicly owned treatment works removes toxic pollutants; (3) the capability of publicly owned treatment works to revise pretreatment requirements under section 307(b)(1) of the Federal Water Pollution Control Act; (4) possible alternative regulatory strategies for protecting the operations of publicly owned treatment works from industrial discharges, and shall evaluate the extent to which each such strategy identified may be expected to achieve the goals of this Act; (5) for each such alternative regulatory strategy, the extent to which removal of toxic pollutants by publicly owned treatment works results in contamination of sewage sludge and the extent to which pretreatment requirements may prevent such contamination or improve the ability of publicly owned treatment works to comply with sewage sludge criteria developed under section 405 of the Federal Water Pollution Control Act; and (6) the adequacy of Federal, State, and local resources to establish, implement, and enforce multiple pretreatment limits for toxic pollutants for each such alternative strategy. (b) Report.—Not later than 4 years after the date of the enactment of this Act, the Administrator shall submit a report on the results of such study along with recommendations for improving the effectiveness of pretreatment requirements to the Committee on Public Works and Transportation of the House of Representatives and the Committee on Environment and Public Works of the Senate.
