Clean Water Act Methods Update Rule for the Analysis of Effluent (Draft)
Nov. 1, 2019
EPA is proposing changes to its test procedures required to be used by industries when analyzing the chemical, physical, and biological properties of wastewater and other environmental samples for reporting under the EPA's NPDES permit program. The CWA requires the EPA to promulgate these test procedures for analysis of pollutants. The EPA anticipates that these proposed changes will provide increased flexibility for the regulated community in meeting monitoring requirements while improving data quality. Comments on this proposed rule must be received on or before December 23, 2019.
