Boulder Waterkeeper Issues Formal Water Quality Complaint to CDPHE Regarding Boulder Creek Sediment

Boulder Waterkeeper is issuing a water quality based complaint against Zak Dirt the permit holder of the above mention general construction stormwater permits. Zak Dirt is the major CDOT contractor for the State Highway 119 Project. It is apparent that erosion control measures are not adequate as per the CDPHE General Stormwater Permit requirements. Sediment in the creek pose a significant risk to trout spawning in Boulder Creek.

An observation was made on September 5, 2019 of unusually high sediment at Eben Fine Park and other locations along Boulder Creek.

On September 8, 2019 a drive through of the construction area showed poor erosion control measures being instituted by the Contractor with large amounts of open exposed sediment near Boulder Creek.

Boulder Waterkeeper is requesting the Army Corps of Engineers and Colorado Department of Public Health & Environment visit the site to assess the environmental impact and permit compliance.
