Olin Corporation is an American manufacturer of ammunition, chlorine, and sodium hydroxide. The company traces its roots to two companies, both founded in 1892: Franklin W. Olin's Equitable Powder Company and the Mathieson Alkali Works. Accidents at Olin chemical plants have exposed employees and nearby residents to health hazards.[2][3][4]
History
Founding and expansion (1890s-1900s)
The company was started by
In 1944, the various Olin companies were organized under a new corporate parent, Olin Industries, Inc.[6] At the time, Olin Industries and its subsidiary companies ran the St. Louis Arsenal and contributed to the war effort with manufacturing roles at the Badger Army Ammunition and Lake City Army Ammunition Plants. Olin's New Haven and East Alton plants employed about 17,000 workers each — producing the guns and small-caliber ammunition needed during World War II. The war production helped the Olins to become one of the wealthiest American families of the time.
In 1952, Olin opened a chlorine plant in McIntosh, Alabama.[3] The production process at this facility originally involved mercury, which contaminated the groundwater.[2]
Mathieson Chemical acquisition
After the war, the Olins acquired the Mathieson Chemical Corporation—also founded in 1892.[7][8][9] Long before its association with Olin, Mathieson Alkali Works began business in Saltville, Virginia, and a year later acquired its neighbor, the Holston Salt and Plaster Corp. Saltville became a quintessential company town, where they produced chlorine and caustic soda, and in the process leached methylmercury (by the company's own estimates, up to 100 pounds per day) into the soils and the North fork of the Holston River.[10] The site was declared a Superfund site in 1982.[11]
In 1952, Mathieson Chemical Company, as it was known by then, acquired controlling interest in the pharmaceutical firm of
Olin Industries and Mathieson Chemical merged in 1954 to form the Olin Mathieson Chemical Corporation. The new company had 35,000 employees, 46 domestic and 17 foreign plants. The company manufactured
1924 "Muck Dam Collapse"
Nearly 30 years prior to Olin acquiring Mathieson Chemical, a muck dam collapsed, sending a 30-foot wall of water, mud, mercury, and alkali down the Holston River valley into the company town of Palmertown, a community of Saltville, Virginia. Bodies, homes, and cars were washed as far as seven miles down the valley. In the aftermath of the flood, 19 people had died.[20]
Corporate reduction (1969-2010)

The company became Olin Corporation in 1969 and subsequently began selling-off many of its acquired businesses. Since then, Olin Corporation has been shrinking (except for a brief expansion in the early 1980s).[21]
Olin was the first U.S. corporation to be prosecuted for violations of the

— brief filed in U.S. District Court, New Haven, Conn. (20 March 1978).[23], "Memorandum on Behalf of Olin Corporation"
After ongoing declines in its business at Winchester, on December 12, 1980, Olin made the decision to sell Winchester firearms to the firm's employees under the name
The ammunition business was strengthened by the
The McIntosh chlorine plant began using asbestos, a potent carcinogen, in 1978. The chemical was not safely contained, and employees regularly breathed it in and were not given protective equipment. The company was aware of the hazard and told workers that they could stay safe by preventing the material from becoming airborne. OSHA gave the company advance notice of its inspections, for which they regularly cleaned up the asbestos.[2] The 2007 merger between Pioneer and Olin created the third-largest chlorine producer in the United States.[33] In 2010, an equipment failure at the McIntosh plant released caustic soda into the atmosphere,[3] and the plant frequently releases chlorine into the atmosphere.[2] Residents have complained that they were not adequately informed of the leaks.[2]
Spinoffs and joint ventures (2015-2022)
On March 27, 2015, Dow Chemical Company announced that it would spin off its chlorine and epoxy businesses and merge them with Olin Corporation.[34] Dow earned around $5 billion in the deal including $2 billion in cash, with the new Olin to have revenue of around $7 billion, with Olin chairman and CEO Joseph D. Rupp to lead the new larger company. Separately, Dow also agreed to supply Olin with ethylene.[34] On October 5, 2015, Olin successfully acquired Dow's U.S. Gulf Coast Chlor-Alkali and Vinyl, Global Chlorinated Organics, and Global Epoxy business units, in addition to 100 percent interest in the Dow Mitsui Chlor-Alkali joint venture.[35] As of 2016, Olin president and CEO was John E. Fischer.[36]
In 2016, an Olin Corp. facility on Dow Chemical property in
As of 2021, the Olin Chemical Superfund Site was still undergoing cleanup under Olin Corporation, with the EPA having managed the site 2006, and the 53-acre facility purchased by Olin in 1980.[40] The EPA was overseeing the cleanup of a Olin Corp. facility in East Alton by 2021, taking public comments on Olin's proposed cleanup plan to contaminated soil and groundwater in July 2021.[41] In 2021, Olin shut down half of its diaphragm-grade chlor alkali production at its facility in McIntosh, Alabama.[42]
In 2022, Olin created a joint venture with Plug Power Inc., to produce 15 tons of "green" hydrogen per day at a plant in Louisiana, to be operational by 2023 according to the company.[43] In 2022, it had seven production facilities in the United States and Canada dedicated to chlorine and caustic soda.[citation needed] The former Olin Corporation headquarters in East Alton, after being purchased by the Wieland Group, were razed in 2022. The structure had previously employed 1,800 people when Olin had used it as an ammunition production facility.[30]
Products and divisions
As a producer of ammunition and industrial chemicals, in 2022, the Olin Corporation had three overall business segments: "Chlor-Alkali Products and Vinyls, Epoxy (epoxy materials and precursors), and Winchester (arms and ammunition)."[
