## Abstract

The Environmental Protection Agency (EPA) is correcting a final rule that appeared in the Federal Register of August 19, 2014 (79 FR 49001). The rule finalized minor amendments to its Clean Water Act (CWA) regulations to codify that under the National Pollutant Discharge Elimination System (NPDES) program, in general, permit applicants must use "sufficiently sensitive" analytical test methods when completing an NPDES permit application and the Director must prescribe that only "sufficiently sensitive" methods be used for analyses of pollutants or pollutant parameters under an NPDES permit.
