History
The quarry was originally founded by Henry J. Kaiser as the Kaiser Permanente Cement Plant in 1939, taking the name of the business from the Permanente Creek in whose valley it lies. Kaiser intended to use the quarry to provide the majority of the cement used in the construction of the Shasta Dam, supplying the 6 million barrels (950,000 m3) of cement . The cement plant is the sole reason for the lone railroad line that runs through the city.
On October 5, 2011, the Lehigh Southwest Cement plant was the site of a shooting in which a disgruntled employee shot and killed three people, and wounded seven.
