Exhibit 99.1

BreitBurn Energy Partners L.P. Provides Update on Sunniland Trend

LOS ANGELES, June 8, 2010 -- BreitBurn Energy Partners L.P. (the "Partnership") (NASDAQ:BBEP) today announced results of recent development activity within its Sunniland Trend fields.  An infill development well, the CL & CC 27-5AH, was completed in early May in the Sunniland C formation with over 1,500 feet of pay in the horizontal section at a true vertical depth of 11,407 feet. The well is located in the Raccoon Point Field in onshore Florida. The Sunniland Trend has been producing oil since the first discovery well was drilled in the early 1940’s.  Total production from BreitBurn’s operations in the Sunniland Trend is now approximately 2,850 barrels per day.

After four weeks on production, the CL & CC 27-5AH well is producing approximately 1,200 barrels of oil and 1,500 barrels of water per day through the use of a downhole electric pump.  Reservoir pressure is such that oil cannot reach the surface without the continuous operation of the electric pump.  BreitBurn operates the well with a 100% working interest and an 83.6% net revenue interest.

Mark Pease, BreitBurn’s COO, said, “We are extremely pleased with the initial production from our first horizontal well in the Sunniland Trend.  Our operations team continues to achieve outstanding results in the field, and we are very encouraged by the realized production rate that is more than double the rate used in our pre-drill economics.  Production from the CL & CC 27-5AH now accounts for about 5% of the Partnership’s daily production.  The Sunniland Trend, with its established, long-lived reservoirs, is an excellent MLP asset.  The area is also consistent with our strategy of acquiring complex fields with substantial oil in place.”

BreitBurn is currently drilling a second horizontal well in the Raccoon Point Field and expects results from that well in July.
