This site is intended for operators of gas pipeline systems, including required regulations, reporting tools and any changes in rulemaking.
Colorado Public Utilities Commission (PUC) functions as a safety oversight organization for the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety Administration (PHMSA). We work within their federal standards which are:
- Pipeline Safety Regulations (Title 49 C.F.R. Parts 190-199)
- 49 U.S. Code § 60105 - State pipeline safety program certifications
- 49 U.S. Code § 60106 - State pipeline safety agreements
- Applies only to municipal natural gas pipeline operators.
- 49 USC 60106 Agreement Requirements for PIpeline Safety (Letter to operators)
- Legislative Mandates:
- PIPES Act of 2016, 2020
- Hazardous Materials Safety Improvement Act of 2012
- Pipeline Safety Act of 2011
- The Fixing America’s Surface Transportation Act
- Bipartisan Infrastructure Law (BIL)/Infrastructure Investment and Jobs Act (IIJA)
Their mission is to “protect people and the environment by advancing the safe transportation of energy and other hazardous materials that are essential to our daily lives. To do this, the agency establishes national policy, sets and enforces standards, educates, and conducts research to prevent incidents. We also prepare the public and first responders to reduce consequences if an incident does occur.”
As the PUC, we also follow State regulations §§40-1-103, 40-2-115, 40-7-117, C.R.S. The statutes providing state authority allowing the PUC to enter cooperative agreements with federal agencies and to adopt and create rules to administer and enforce the National Gas Pipeline Safety Act of 1968.

Natural Gas Pipeline Operators
Natural gas pipeline operators in Colorado include:
Operators MUST contact the National Response Center (NRC) for immediate reporting of pipeline incidents as defined in 49 CFR § 191.3 at: 800-424-8802. Reporting must occur within one hour of confirmed discovery. After an NRC control number is assigned, operators must call the PUC’s GPS Telephonic Event/Incident Reporting number at: 303-894-2854.
Operators MUST contact the PUC's GPS Telephonic Event/Incident Reporting number within two hours of confirmed discovery if one of the following occurs (4 CCR 723-11, 11102. Verbal Reporting of Pipeline Incidents and Events):
- An unplanned/emergency event that occurs on the pipeline system that results in the evacuation of 50 or more people from a normally occupied building or property;
- An unplanned/emergency event that occurs on the pipeline system that results in the closure of all lanes in either direction of a roadway or railroad;
- An unplanned/emergency event that occurs on the pipeline system that results in the evacuation of four or more residential structures;
- An unplanned/emergency event that occurs on the pipeline system that results in a service outage of 100 or more customers.
- An event that requires active soil vapor extraction for a period exceeding 48 hours as measured from the time the extraction device is turned on at the site until the operator determines soil vapor extraction is no longer necessary.
- A Maximum Allowable Operating Pressure (MAOP) exceedance event that requires the operator, pursuant to its procedures, to implement follow-up actions such as a leak survey; OR
- An event that, in the opinion of the operator, requires courtesy notification to the Pipeline Safety Program.
If the expedited reporting time for a pipeline event exceeds two hours after confirmed discovery, the operator shall provide a written explanation for the exceedance to the PSP Chief within ten business days after the event.
Operators must file SRC Reports by email to InformationResourcesManagement@dpt.gov, or by facsimile to (202)366-7128 and must concurrently inform the PSP Chief through e-mail at dora_copuc_pipeline_safety@state.co.us and submit the SRC report to Commission through its E-Filings System in accordance with subparagraph 1204(a)(III) of the Commission’s Rules of Practice and Procedure in the repository proceeding opened for such reporting purposes no later than close of the next business day.
