The provisions of C.R.S. sections 25-8-202; 25-8-203; 25-8-204; 25-8-402, provide the specific statutory authority for adoption of this regulation. The Commission also adopted, in compliance with section 24-4-103(4) the following statement of basis and purpose.
BASIS AND PURPOSE
In today's action, the Commission updated the maps to an electronic format in ArcGIS, which are publicly available. The geographic regions in Regulation No. 42 represent where the Water Quality Control Commission has assigned use classifications and site specific water quality standards. No changes were made to the actual boundaries. These changes were made to better communicate all of the specified areas within Regulation No. 42 with external stakeholders. The maps are found in Figures 1 through 54B in the regulation.
