| Abstract |
EPA has assessed current procedures for determining the sensitivity of test methods and their application to Clean Water Act (CWA) Programs. The assessment was required by a settlement agreement with the Alliance of Automobile Manufacturers, et al. We announced the availability of our preliminary assessment for public comment on March 12, 2003. This assessment discussed statistical, chemical, and regulatory issues related to detection and quantitation and different approaches to detection and quantitation. The Agency has revised the preliminary assessment Document to incorporate public comment on that assessment. In a related action on March 12, 2002, we proposed to revise EPA's method detection limit (MDL) definition and procedure, and codify our minimum level (ML) procedure. The MDL and ML, respectively and in order of increasing magnitude, are the EPA's embodiment of a detection and a quantitation limit. |
