ECOLOGICAL EVALUATION OF PROPOSED DISCHARGE OF DREDGED OR FILL MATERIAL INTO NAVIGABLE WATERS: INTERIM GUIDANCE FOR IMPLEMENTATION OF SECTION 404 (B) (1) OF PUBLIC LAW 92-500 (FEDERAL WATER POLLUTION CONTROL ACT AMENDMENTS OF 1972)
Thie Interim Guidance is to be used for the ecological evaluation of the proposed discharge of dredged or fill material in navigable waters according to Section 404(b) of Public Law 92-500. The Interim Guidance outlines the basic philosophy of the ecological evaluation of dredged and fill material discharges and outlines the general procedures to make this evaluation. Important is an ecological evaluation are the selection of appropriate test(s) and interpretation of results for assessment of potential problems. General approaches for technical evaluation are partitioned into physical effects, chemical-biological interactive effects, and procedures for site comparison. The Interim Guidance presents the General sequence of testing and evaluative procedures given in the Federal Register and presents detailed stepwise procedures for conducting an elutriate test, estimating a mixing zone, perforing bioassays, conducting total sediment analyses, and evaluating biological community structure. These procedures contain all references and citations pertinent to the various evaluative procedures.
