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

Lower Arkansas Segment 1a (COARLA01a): The Commission reviewed the discharger specific variance (DSV) for acute and chronic selenium, and chronic sulfate, adopted in the June 2018 Arkansas Basin Hearing for the City of Pueblo's James R. DiIorio Water Reclamation Facility. See Section 32.6 . The Commission reviewed Pueblo's progress toward achieving the narrative alternate limits (AELs) for selenium and sulfate, and determined that the narrative AELs continue to represent the highest attainable water quality that is feasible for Pueblo to achieve. Therefore, the Commission determined that the selenium and sulfate DSV is still appropriate and does not require revision at this time.
