Plains All American Pipeline (PAA) partially shut its Line 63 crude pipeline in East Los Angeles on May 22, 2026. A third-party construction crew accidentally ruptured the line during excavation.
The pipeline leaked approximately five gallons of oil per second. Operators successfully halted the flow after 30 minutes. Line 63 transports San Joaquin Valley crude to regional facilities and refineries.
PAA units closed up 1.98% to reach $24.15. Rising crude oil futures drove the stock gains, outweighing the impact of the localized rupture.
