Guidelines Establishing Test Procedures for the Analysis of Pollutants Under the Clean Water Act; Analysis and Sampling Procedures; Extension of Comment Period

On September 23, 2010, EPA proposed changes to analysis and sampling test procedures in wastewater regulations. These changes will help provide additional flexibility to the regulated community and laboratories in their selection of analytical methods (test procedures) for use in Clean Water Act programs. EPA requested that public comments on the proposal be submitted on or before November 22, 2010 (a 60-day comment period). Since publication, the Agency has received several requests for additional time to submit comments. EPA is extending the period of time in which the Agency will accept public comments on the proposal for an additional 30 days.
