2040-AF84 201904 Unified Agenda of Federal Regulatory and Deregulatory Actions 2040 Office of Water OW 2000 Environmental Protection Agency EPA Clean Water Act Methods Update Rule for the Analysis of Effluent

This regulatory action would amend "Guidelines Establishing Test Procedures for the Analysis of Pollutants" at 40 CFR part 136 by approving test procedures (analytical methods) for use by testing laboratories and others for water monitoring. These test procedures must be used to implement the NPDES program unless the U.S. Environmental Protection Agency (EPA) has approved the use of an alternate procedure. The regulation would also revise, clarify, and correct errors and ambiguities in existing methods and the water monitoring regulations.
