1. RULEMAKING The provisions of sections 25-8-202 and 25-8-401, C.R.S., provide the specific statutory authority for adoption of the attached regulatory amendments. The Commission also adopted, in compliance with section 24-4-103(4) C.R.S., the following statement of basis and purpose. BASIS AND PURPOSE The Commission has adopted a revised numbering system for this regulation, as a part of an overall renumbering of all Water Quality Control Commission rules and regulations. The goals of the renumbering are: (1) to achieve a more logical organization and numbering of the regulations, with a system that provides flexibility for future modifications, and (2) to make the Commission’s internal numbering system and that of the Colorado Code of Regulations (CCR) consistent. The CCR references for the regulations will also be revised as a result of this hearing.

65.12 STATEMENT OF BASIS, SPECIFIC STATUTORY AUTHORITY AND PURPOSE; JULY 11, 2005 RULEMAKING, EFFECTIVE OCTOBER 2, 2005 The provisions of sections 25-8-205 and 25-8-401, C.R.S., provide the specific statutory authority for adoption of the attached regulatory amendments. The Commission also adopted, in compliance with section 24-4-103(4) C.R.S., the following statement of basis and purpose. BASIS AND PURPOSE The Commission modified section 65.2(1) of the regulation to clarify that the discharge of pollutants from any point source to a storm sewer without a discharge permit is prohibited. The Commission found this change to be appropriate to clarify that “point sources” are not limited to certain types of facilities. The Commission deleted previous section 65.2(2) as it was redundant of section 65.2(1) and also revised section 65.2(3), now 65.2(2), for consistency with those of section 65.2(1).
