Draft 401 certifications for discharges from federal facilities

Under section 401 of the Clean Water Act a federal agency may not issue a permit or license to conduct any activity that may result in any discharge into federal waters in Colorado unless Colorado issues a Section 401 water quality certification.  These certifications may include additional permit conditions needed to protect Colorado waters.

EPA issues discharge permits for federal facilities in Colorado. Colorado has received EPA draft permits for the following activities and is requesting comment on draft certifications for these activities.
