Aeromonas and NDPWR Methods Rule
The comment period is closed on the rule titled "Unregulated Contaminant
Monitoring Regulation: Approval of Analytical Method for Aeromonas;
National Primary and Secondary Drinking Water Regulations: Approval of
Analytical Methods for Chemical and Microbiological Contaminants; Proposed Rule,"
(PDF, 181KB) March 7, 2002.
This rule proposed the analytical method and an associated Minimum Reporting
Level (MRL) for the analysis of Aeromonas to support the Unregulated
Contaminant Monitoring Regulation's List 2 monitoring. Additionally, EPA
proposed to approve EPA Method 515.4 to support previously required National
Primary Drinking Water Regulation (NPDWR) compliance monitoring for 2,4-D
(as acid, salts and esters), 2,4,5-TP (Silvex), dinoseb, pentachlorophenol,
picloram and dalapon, and EPA Method 531.2 to support previously required
NPDWR monitoring for carbofuran and oxamyl. Finally, EPA proposed to approve
eight additional industry developed analytical methods to support previously
required NPDWR compliance monitoring. The following table lists the analytical
methods proposed in this action and the regulated or UCMR analytes that
they measure.
