The provisions of C.R S. 25-8-202(1)(a), (b) and (2); 25-8-203; 25-8-204; and 25-8-402; provide the specific statutory authority for adoption of these regulatory amendments.  The Commission also adopted in compliance with 24-4-103(4) C.R.S. the following statement of basis and purpose.
BASIS AND PURPOSE
The Commission has decided to delay the basin-wide review of water quality classifications and standards for this basin until June 2014, to accommodate an issue-specific rulemaking for nutrient criteria in June 2011.  Consistent with that decision, the Commission has also decided to extend the effective date for the Grand Lake clarity standard to January 1, 2015.
