The Methodology is guidance for scientific human health assessments used by EPA to develop, publish, and from time to time revise, recommended criteria for water quality accurately reflecting the latest scientific knowledge. The recommended criteria serve States and Tribes' needs in their development of water quality standards under Section 303(c) of the CWA.Item Procedures for Initiating Narrative Biological Criteria(United States Environmental Protection Agency, 1992-10) United States Environmental Protection Agency Office of Science and Technology; United States Environmental Protection Agency Office of WaterThe Biological Criteria Program was initiated by EPA in response to research and interest generated over the last several years by Agency, State, and academic investigators. This interest has been documented in several reports and conference proceedings that were the basis for creation of the program and for the preparation of Biological Criteria National Program Guidance for Surface Waters (U.S. Environ. Prot. Agency, 1990a). The overall concept and "narrative biological criteria" are described in that guide. Because establishing narrative criteria is an important first step in the process, the material that follows here is intended to be an elaboration upon and clarification of the term narrative biological criteria as used in the guide. The emphasis here is on a practical, applied approach with particular attention to cost considerations and the need to introduce the material to readers who may not be familiar with the program.
