Pennwalt plant. Located on 40 acres in the industrial Tacoma tideflats, the company was first known as the Pennsylvania Salt Manufacturing Co. of Washington or Pennsalt. Pennwalt was an inorganic chemical manufacturer of chlorine gas, caustic soda, liquid chlorine and hydrogen gas. Doing business in Tacoma since 1929, its caustic soda and liquid chlorine were in demand by the Northwest's pulp and paper industry. Photograph ordered by Pennwalt Corp.

Water view of Pennwalt Corp. shortly after Christmas, 1969. By 1969, Pennwalt (formerly known as Pennsalt or Pennsylvania Salt Manufacturing Co. of Washington) had been operating in Tacoma for 40 years. The company was located on 40-acres of land in Tacoma's Tideflats along the Hylebos Waterway. A leader in chemical production, it would merge with Wallace & Tiernan to form Pennwalt Corp. in 1969. More changes and mergers would occur and by 2004, the company would be known as Arkema, Inc. Photograph ordered by Pennwalt Corp.

This view on December 26, 1969, shows one of the large piles of salt used by Pennwalt in daily operations. Doing business in Tacoma since 1929, Pennwalt had originally specialized in caustic soda and liquid chlorine for sale to the Pacific Northwest's pulp and paper industry before diversifying.

Aerial view of Pennsylvania Salt Manufacturing Co. Storage tanks dot the area around the plant and one of the Pennwalt barges can be seen being maneuvered to the dock by two tugs. The large corporation, now known as Pennwalt, had its beginnings in 1850 when five Philadelphia Quakers organized the Pennsylvania Salt Manufacturing Co. and constructed a plant to produce lye and alkaline salts of soda from natural salt. Today Pennwalt, with its headquarters in Philadelphia, is a worldwide manufacturer of chemicals, health products and precision equipment. The chlorine produced by the company is used in paper and pulp manufacturing, but also in water purification, bleach and the manufacture of adhesives. Caustic soda is also used in pulp production.

Storage tanks dot the area around the plant and one of the Pennwalt barges can be seen being maneuvered to the dock by two tugs. In 1928, the eastern firm was invited to build a caustic soda and liquid chlorine plant on 14 acres of filled ground adjacent to the Hylebos Waterway. The plant opened the following year as Tacoma ElectroChemical Company. As the parent firm diversified the plants' chemical production, it became known as Pennsalt, and then Pennwalt. Pennwalt Corp. was taken over by Elf-Atochem in 1990. ("South on the Sound" by Murray Morgan)

E.L. Cliffe (L), plant superintendent, and Col. Edward Schmitt, commanding officer of the Army Personnel Center, Ft. Lewis, met with Pennsalt employee William Otto at the company's facilities on November 10, 1954. Col. Schmitt toured the plant in preview of industry tours for military personnel on Armed Forces Appreciation Day, November 30th. Mr. Otto shows the two men the machinery used in making corrosion-resistant molds used in the manufacture of chlorine and caustic by Pennsalt. Other companies, including Puget Sound Plywood, Brown & Haley, Heidelberg Breweries and Hooker Electrochemical, would also be offering tours for the military on Armed Forces Appreciation Day.

Aerial view of Pennsylvania Salt Manufacturing Company. The Tacoma plant covers nearly 40 acres of tideflats on the Hylebos waterway. This location was chosen in 1929 because of favorable electric power rates, availability and quality of water, access to water, rail and motor transportation and its central location for its principal customers, the pulp and paper mills. The name of the corporation was changed to Pennwalt Corp. prior to the merger of Pennsalt and Wallace & Tierman, Inc. (TNT, 11/29/1968)
