Proposed Best Demonstrated Available Technology (BDAT) Background Document for Wastewaters Containing BDAT List Constituents. Volume 6

摘要

The background document presents a technical database of wastewater treatment performance data for BDAT List constituents. In addition, the document provides the Agency's retionale and technical support for selecting specific treatment performance data for use in calculating a BDAT wastewater treatment standard for each BDAT List constituent. The Agency's legal authority and promulgated methodology for establishing treatment standards is summarized in EPA's methodology for developing BDAT treatment standards. The background document presents the sources of treatment performance data used for evaluation of BDAT, the criteria used in screening data from these sources, and the criteria used by the BDAT program (BDAT Methodology) for screening data for use in determining BDAT. The document presents wastewater treatment performance data available for each BDAT List constituent, a discussion of which data were used as BDAT, and presents the calculation of BDAT treatment standards.
