2040-AF84 202004 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 amends '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 for measurements required for an application for an EPA or State National Pollutant Discharge Elimination System (NPDES) permit, for reports submitted by NPDES dischargers and for certifications issued by States under section 401 of the Clean Water Act. The regulation also revises, clarifies, and corrects errors and ambiguities in existing methods and the water monitoring regulations.
