On May 15, 2013 the Missouri Public Service Commission updated their gas pipeline regulations found in the Code of State Regulations (CSR) Title 4 Division 240 Chapter 40 Gas Utilities and Gas Safety Standards. In addition to editorial changes, the following more significant changes were made:

4 CSR 240-40.020 Incident, Annual and Safety-Related Condition Reporting

• Exempted pipelines that operate at less than 0 psi and pipelines that are not a regulated onshore gathering line (as determined in 4 CSR 240-40-030(1)(E)).
• Updated the definition of an incident to exclude the cost of gas from the $50,000 reporting threshold and add a three million cubic feet threshold for reporting unintentional estimated gas loss.
• Rather than requiring a telephonic report, an immediate notification must be made to the National Response Center by either telephone or electronically at NRC.USCG.MIL
• Updated PHMSA reporting requirements to match the report submission requirements found in 49 CFR 191.
• Require a federal incident report be filed within 30 days after detection of an incident on the incident form revised June 2011.
