Water Protection Program
Antidegradation Implementation
As of Aug. 30, 2008, all permit applications for new or expanded discharges are required to follow the Missouri Antidegradation Rule and Implementation Procedure. The Antidegradation Review process will be initiated by requests for water quality based effluent limits.
Antidegradation Rule and Implementation Procedure- Approved April 20, 2007 and revised on May 2, 2012.
The department has changed all fill-in forms from Word format to PDF fill-in. You will be able to save and reuse these PDF forms. However, you will need Adobe Acrobat Reader 7 or higher to save the PDF fill-in form.
