Water Quality Open Public Notices

Public comment is a prerequisite to challenging permitting decisions. Under Utah Code Ann., Section 19-1-301.5 (effective May 8, 2012), a person who wishes to challenge a Permit Order may only raise an issue or argument during an adjudicatory proceeding that was raised during the public comment period and was supported with sufficient information or documentation to enable the Director to fully consider the substance and significance of the issue.
