Edward Hanousek worked for Pacific & Arctic Railway and Navigation Company (P&A) as a roadmaster of the White Pass & Yukon Railroad in Alaska. As an officer of the corporation, Hanousek was responsible "for every detail of the safe and efficient maintenance and construction of track, structures, and marine facilities of the entire railroad," including special projects. One project was a rock quarry, known as "6-mile," above the Skagway River. Next to the quarry, and just beneath the surface, ran a high-pressure oil pipeline owned by Pacific & Arctic Pipeline, Inc., P&A's sister company. When the quarry's backhoe operator punctured the pipeline, an estimated one thousand to five thousand gallons of oil were dis- charged into the river.
