# AGENCY:

Environmental Protection Agency (EPA).

# ACTION:

Proposed rule; extension of the public comment period.

# SUMMARY:

On September 23, 2010, EPA proposed changes to analysis and sampling test procedures in wastewater regulations.

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.

# DATES:

The comment period for the proposed rule published September 23, 2010, at 75 FR 58024 is extended. Comments must be received on or before December 22, 2010. Comments postmarked after this date may not be considered.
