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

Pursuant to the requirements in the Basic Standards (at 31.7(3)), the commission reviewed the status of temporary modifications scheduled to expire before December 31, 2019 to determine whether the temporary modification should be modified, eliminated, or extended.

No action: The commission took no action on the temporary modifications on the following segments:

Rio Grande Segments 4a and 7: temporary modifications of the standards on Rio Grande Segment 4a (cadmium, lead, zinc, and ammonia) and Segment 7 (cadmium, copper, lead, silver, zinc, ammonia); expire 12/31/2018. Both the Town of Creede and Rio Grande Silver presented evidence that they are making progress on the plan for eliminating the need for the temporary modifications. The commission took no action on the temporary modifications on these two segments as the original time allotment was deemed adequate to resolve the uncertainty.
