HL Outside of HCA Performance Measures

Since 2020, hazardous liquid pipeline operators have been required to annually submit data for inspection, repair, and assessment of pipeline facilities outside of could affect High Consequence Areas (HCA). PHMSA uses data from these reports, which are due on June 15th for the previous calendar year, to summarize industry progress on assessing pipeline facilities outside of could affect HCA.

HL Outside of HCA Performance Measures shows trends for miles outside of HCA, large spills outside of HCAs, outside of HCA miles assessed (both baseline and reassessment), and outside of HCA repairs. The definitions below provide additional details about the reporting criteria. Operators submit this data separately for inTERstate and inTRAstate pipelines. The data is submitted by individual State for inTRAstate pipelines. Use the Inter/Intra prompt and State prompt to tailor the reports to the data you want to see.

Definitions:

Large Spills are accidents including one or more of these consequences:

1. death or personal injury requiring hospitalization
    
2. property damage greater than $50,000
    
3. more than 5 barrels released
    
4. fire or explosion
    
5. pollution of water

Accidents are releases of hazardous liquid or carbon dioxide from a pipeline that results in one or more of the following consequences: a death or personal injury necessitating in-patient hospitalization; estimated property damage of more than $50,000; a release of 5 gallons or more of hazardous liquid or carbon dioxide (or 5 barrels or more resulting from most types of maintenance activity); or, an explosion or fire not intentionally set by the operator.

Immediate Hazard Repair – as explained in 49 CFR 195.401(b)(1), a condition outside of could affect HCA that could adversely affect the safe operation of a pipeline system.

Non Immediate Repair – a condition outside of could affect HCA that is not an Immediate Hazard Repair

Pressure Test Failure Repair - These repairs result when failures occur due to pressure tests conducted by operators, typically involving the use of water as the test medium.
