RULES REGULATING GAS UTILITIES
4 CCR 723-4
[Editor’s Notes follow the text of the rules at the end of this CCR Document.]
BASIS, PURPOSE, AND STATUTORY AUTHORITY.
The basis and purpose of these rules is to set forth the manner of regulation over
jurisdictional gas utilities, the services they provide, and their actions to maintain just
and reasonable rates, ensure system safety, reliability, and resiliency, protect
disproportionately impacted communities, and reduce greenhouse gas emissions from
the use of gas by their customers and from leaks in their facilities. These rules also set
forth the manner of regulation over master meter operators. These rules address a wide
variety of subject areas including, but not limited to, planning, expenditure and demand
forecasting, cost and rate impacts, system safety and integrity planning, service
interruption, meter testing and accuracy, safety, customer information, customer
deposits, rate schedules and tariffs, discontinuance of service, master meter operations,
transportation service, flexible regulation, procedures for administering the Low-Income
Energy Assistance Act, gas service low-income programs, cost allocation between
regulated and unregulated operations, recovery of gas costs, appeals regarding local
government land use decisions, demand side management programs, the reduction of
greenhouse gas emissions from the distribution and end-use consumption of gas, and
authority of the Commission to impose civil penalties on public utilities. The statutory
authority for these rules can be found at §§ 29-20-108, 40-1-103.5, 40-2-108, 40-3-102,

utility serves fewer than 50,000 gas customers.
(c)
No Tier III utility is required to:
(I)
include in its tariffs a description of standard and non-standard customer
data that the utility is able to provide to the customer or to any third party
recipient (see paragraph 4027(c));
(II)
provide customer notice each year regarding customer data (see rule
4028);
(III)
make customer consent forms for the disclosure of customer data
available to customers or third parties (see rule 4029);
