On February 18, 2009, Mid Valley Pipeline’s 22” Maumee Pipeline (Lima to Cygnet) experienced a leak at a 12” diameter branch connection. The damaged pipeline, which was operating at the time, released 1250 barrels of crude oil into a farm field. Eventually, 782 of the 1250 barrels released were recovered. Some of the crude oil, approximately 200 barrels, did contaminate a local creek. There were no fatalities, or injuries. One person was evacuated for several hours. The release did occur in a high consequence area (drinking water). A PHMSA engineer conducted an on-site investigation of the failure. The investigative summary is as follows: The failure occurred at approximately 3:00 p.m. EST on February 18, 2009. The failure is located near milepost marker 46, in a rural area of Wood County, south of Cygnet, OH. The failure was detected at 4:55 p.m. the same day when a Mid Valley Pipeline (MVP) employee driving near the Cygnet pump station discovered a pool of crude oil on the ground surface. The employee notified the MVP control center, which immediately shut down the Maumee Pipeline. MVP blocked in the line segment at 5:00 p.m. by remotely isolating the upstream (Lima) and downstream (Cygnet) pump stations. The pipeline was repaired and placed back in service on February 18, 2009. In July 2003, MVP de-commissioned the 12” branch line. At the time of failure, the branch connection contained the attachment weld, approximately 50-inches of 12” diameter pipe, a 12” diameter valve (flanged) and a blind flange. Beyond the blind flange, the 12” branch connection piping was removed. The pipeline experienced a crack in the 12” branch connection attachment weld. The crack developed at the top (12 O’clock) position of the attachment weld, oriented circumferentially with the branch connection and longitudinally with the Maumee Pipeline. The crack measured 11” long and 0.125” at the maximum width. The driving stress for the crack was produced by the combined loading of the 22” x 12” diameter branch connection, the valve, flanging and somastic “mass” on the attachment weld. The portion of the pipeline containing the failure is comprised of 22” diameter by 0.344” wall thickness API 5L - Grade B, seamless pipe, installed in 1949. The 12” diameter nominal branch line was attached at the 9 O’clock position to the mainline with a self reinforcing weld-on outlet fitting. The reported maximum operating pressure (MOP) is 788 psig. The operating pressure at the time and location of the failure was 470 psig. The MOP was established in accordance with 195.303, Risk Based Alternative to Pressure Testing. The pipeline external corrosion protection system consists of a Somastic coating and distributed galvanic anodes. - 1 - Form 11 Pipeline Failure Investigation Report (Revised 03/07/08)#

Page 2Pipeline Failure Investigation Report MVP identified two additional de-commissioned branch connections in the Maumee Pipeline System as a result of this failure. These branch connections were cut out and removed from the Maumee Pipeline System. The Maumee Pipeline System is a 994 mile long crude oil pipeline running from Longview, TX to Samaria, Michigan.

The branch connection was transported to Kiefner and Associates for failure analysis (Appendix 5). The 80” long section of pipe was replaced with pretested pipe and the tie-in girth welds were radiographed. Mid Valley Pipeline initiated a cleanup of the crude oil near the branch connection. Unfortunately, crude oil found its way into the Rocky Ford Creek and Mid Valley Pipeline launched an extensive stream cleanup program under the direction of Ohio EPA and US EPA Region 5. - 14 - Form 11 Pipeline Failure Investigation Report (Revised 03/07/08)#
