On July 27, 2015, EPA announced the availability of the draft recommended aquatic life water quality criterion for selenium in a previous notice entitled “Request for Scientific Views: Draft Recommended Aquatic Life Ambient Water Quality Chronic Criterion for Selenium—Freshwater 2015” in the Federal Register (80 FR 44350). EPA's recommended aquatic life water quality criteria provide technical information for states and authorized tribes to adopt water quality standards under the Clean Water Act to protect aquatic life.

EPA is extending the public comment period for the Draft Aquatic Life Ambient Water Quality Criterion for Selenium—Freshwater 2015 (EPA-822-P-15-001). The original comment deadline was September 25, 2015. This action extends the comment period for 15 days. Written scientific views must now be received by October 10, 2015.

Following closure of the public comment period, EPA will consider the public comments and revise the document as necessary. EPA will then publish a Federal Register notice announcing the availability of the final updated selenium criterion.
