Water Quality Standards Workgroup

Description

This group will assist the department in evaluating the need for greater regulatory processes for protection of wetlands and unclassified waters. The group will also identify the beneficial uses existing in and on these waters and establishes the criteria for protecting those uses. The new criteria should better reflect the diversity in biological communities in Missouri's streams.

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.
