Section 5 CCR 1002-38.102 - STATEMENT OF BASIS, SPECIFIC STATUTORY AUTHORITY AND PURPOSE; DECEMBER 14, 2020 RULEMAKING; FINAL ACTION DECEMBER 14, 2020; EFFECTIVE DATE FEBRUARY 14, 2021

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 deleted the temporary modification for chronic arsenic on Upper South Platte Segment 11b (COSPUS11b), which had an expiration date of 12/31/2024. An arsenic temporary modification was inadvertently adopted on this segment during the 2020 Regulation No. 38 rulemaking hearing; however, the temporary modification is more stringent than the underlying standard.
