## Document text

These rules foster the examination of capital investment of gas distribution utilities that
are subject to the Commission’s regulatory authority through the development and
approval of gas infrastructure plans, planned projects, and alternatives to planned
projects. The purpose of these rules is to establish a process to determine the need for,
and potential alternatives to, capital investment, consistent with the objectives of
maintaining just and reasonable rates, ensuring system safety, reliability, and resiliency,
protecting income-qualified utility customers and disproportionately impacted
communities, and supporting utility efforts to meet applicable clean heat targets
pursuant to rule 4728, as established in § 40-3.2-108, C.R.S.
