4 Colo. Code Regs. § 723-4-4725
These rules implement § 40-3.2-108, C.R.S., for gas distribution utilities and small gas distribution utilities. Consistent with statutory requirements including the statewide greenhouse gas pollution goals set forth in § 25-7-102(2)(g), C.R.S., the purpose of these clean heat plan rules is to maximize methane and carbon dioxide emissions reductions from the distribution and end-use consumption of gas while also maintaining just and reasonable rates, maintaining system safety, reliability and resiliency, and prioritizing investments in disproportionately impacted communities. The utility must utilize clean heat resources to the maximum extent practicable and count greenhouse gas emission reductions resulting from the use of those resources.
