Item 8.01. Other Events.

     As previously disclosed by Pacific Energy Partners, L.P. (Pacific), one of its subsidiaries, Pacific Pipeline System, LLC, experienced a pipeline rupture, caused by a landslide, a natural occurrence, in the Pyramid Lake area of Los Angeles County, which allowed a release of crude oil in 2005. Plains All American Pipeline, L.P. (PAA) now owns Pacific Pipeline System, LLC as a result of the recent merger of Pacific with and into PAA. PAA has been informed that the U.S. Environmental Protection Agency may be intending to initiate proceedings to assess civil penalties against Pacific Pipeline System, LLC. PAA is filing this Current Report on Form 8-K because applicable securities regulations require disclosure of any governmental proceeding involving environmental laws unless there is a reasonable belief that resulting penalties would be less than $100,000. PAA understands that the maximum permissible penalty that the EPA could assess under relevant statutes would be approximately $3.7 million. PAA believes that several mitigating circumstances and factors exist that could substantially reduce the penalty, and intends to pursue discussions with the EPA regarding such mitigating circumstances and factors.
