Water Quality Standards Workgroup

Description

This group will assist the department in developing and refining appropriate water quality standards for the protection of streams, lakes and wetlands that are waters of the state. The group will help identify and designate existing and attainable beneficial uses in and on these waters, and will also help revise and establish the criteria for protecting those uses. The new criteria should better reflect the most recent understanding of the science and the regulatory obligations extending to Missouri's waters.

Timeline:
No specific deadline has been developed for this task, however, issues for discussion were identified during the 2014 solicitation of items to be included in the next triennial review of the WQS - Public Notice of Intent to Initiate Triennial Review.
