In 1988 Colorado’s Legislature created the Authority
Regulation #72. Cherry Creek Reservoir Control Regulation
The Colorado Department of Public Health and Environment Water Quality Control Commission, acting under authorization from the Colorado Water Quality Control Act, established Regulation 72 as the basis for protecting the Cherry Creek Reservoir’s quality.
In 2022, Regulation 72 was updated to streamline and modernize stormwater management requirements. Some municipal stormwater separate sewer system (MS4) permit requirements are still required to comply with the 2012 version of the regulation until their MS4 permits are renewed or modified. For this reason, both the 2012 and 2022 versions of Regulation 72 are provided in the links below.
