Proposed NPDES Rule Requires ‘Sufficiently Sensitive’ Test Methods
Monday, August 2nd, 2010In a Federal Register notice published June 23, the EPA proposed changes to its permitting program under the Clean Water Act (CWA) to ensure the use of sufficiently sensitive analytical methods for monitoring chemical pollutants in discharge water.
Specifically, the new rule affects the CWA’s National Pollutant Discharge Elimination System (NPDES). Its purpose is to specify that applicants and permittees must use analytical methods that are capable of detecting and measuring pollutants at, or below, current water quality criteria.
