{"abstract":"The Environmental Protection Agency (EPA) is proposing changes to its test procedures required to be used by industries and municipalities when analyzing the chemical, physical, and biological properties of wastewater and other environmental samples for reporting under the EPA's National Pollutant Discharge Elimination System (NPDES) permit program. The Clean Water Act requires the EPA to promulgate these test procedures (analytical methods) 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. In addition, this proposed update to the CWA methods would incorporate technological advances in analytical technology. As such, the EPA expects that there will be no negative economic impacts resulting from these proposed changes.","action":"Proposed rule.","agencies":[{"raw_name":"ENVIRONMENTAL PROTECTION
