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.

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.
