out at a MAPCO pipeline pumping station and Terminal in Ogden, Iowa, threatening 4 propane storage tanks for a time. There were no injuries. In June, a Williams Partners pipeline terminal near Lawrence, Kansas spilled about 33,600 gallons of gasoline. The next spring, a rancher nearby was still having gasoline entering a creek on his property. An explosion on July 8 at Trans-Alaska Pipeline System Pump Station No. 8 killed one worker, injured 5 others, and destroyed the pump station. Over $2 million in damage was done. A US House of Representatives Committee later announced the cause was workers not following the proper procedures, causing crude oil to flow into a pump under repair at the time. On July 19, the Trans-Alaska Pipeline System pipeline was shut down for the 4th time in a month, when it was hit in a valve by a front loader. More than of crude oil was spilled. A 12-inch propane pipeline ruptured near Ruff Creek, in Greene County, Pennsylvania, from stress corrosion cracking, on July 20. The resulting propane vapor cloud ignited, when a truck that was driven into the cloud stalled, then created a spark, when it was restarted. The two men in the truck were killed, as well as 57 head of cattle, along with destruction of power lines and wooded areas. Subsidence of underground coal mines in the area may have hastened the failure. A cast iron gas main broke in Cherokee, Alabama on July 30. Gas migrated into a home through a recently back filled sewer line trench, and exploded 5 days later. In August, a car drove through leaking liquid from a petroleum pipeline in Lakewood, California. The pooled liquid appeared to be mud, but it exploded and burned, injuring a woman in the car. On August 9, natural gas under 20 psi pressure entered a 6-ounce per square inch gas distribution system in El Paso, Texas, over pressuring 750 gas customers. Numerous small fires resulted from this. The cause was an error during gas pipeline replacement. On August 15, crude oil spilled at Trans-Alaska Pipeline System Pump Station No. 9. There was no fire, but a fire or explosion at that station could have shut down that pipeline, since Pump Station No. 8 was out of service from the previous month's accident there. This was the seventh accident on this pipeline since the start up of the Alaska
