In February 2002, Simplot agreed to buy equipment and pay penalties related to an unreported release of 80,000 pounds of
sulphur dioxide from a facility in
Pocatello, Idaho. The company violated the
Emergency Planning and Community Right to Know Act by failing to immediately notify the Power and Bannock Counties' Local Emergency Planning Committees or the State Emergency Response Commission of the release. In February 2004, J.R. Simplot Company agreed to pay the
United States Environmental Protection Agency $525,000 and install $2 million in air pollution control equipment to resolve violations of the federal
Clean Air Act at its silica sand mining facility in
Overton, Nevada. The violation occurred in 1988 when the company removed equipment required by the federal Clean Air Act to control emissions of air pollutants. In early 2012, Simplot submitted a report to the Environmental Protection Agency to explain its view regarding how and why pollution limits could be eased in phosphate mine areas, and linking to livestock die-offs of sheep and cattle in other areas. Simplot is one of six major companies to join the
Obama Administration in an effort to significantly reduce energy use over the next 10 years. The company has received awards including the Utah Board of Oil, Gas and Mining's
Earth Day award for the environmental work completed in Nevada. In June 2012, Simplot partnered with two conservation groups and three
phosphate mining companies in an effort to improve the water quality of the
Blackfoot River in
Eastern Idaho. The parties are: J.R. Simplot Company,
Monsanto and
Agrium/Nu-West Industries, the
Idaho Conservation League and
Trout Unlimited. More recently, Simplot settled with the U.S. Environmental Protection Agency and U.S. Department of Justice resolving alleged Clean Air Act violations related to modifications made at Simplot's five
sulfuric acid plants near Lathrop, Calif., Pocatello, Idaho and Rock Springs, Wyo. Under the settlement, Simplot was required to spend an estimated $42 million to install, upgrade and operate pollution controls that significantly cut sulfur dioxide emissions at all five plants, fund a wood stove replacement project in the area surrounding the Lathrop plant, and pay an amount of $899,000 as civil penalty. The company settled with the U.S. Environmental Protection Agency and U.S. Department of Justice resolving Simplot's liability for alleged violations at the Rock Springs, Wyoming facility under the Resource Conservation and Recovery -Act (RCRA), including failure to determine if a solid waste is a
hazardous waste (40 C.F.R. § 262.11); treatment, storage or disposal of hazardous waste in the phosphogypsum (gypsum) stack without a permit or interim status (42 U.S.C. § 6925(a) and 40 C.F.R. Parts 264/265 and 270); failure to perform land disposal determinations and to meet land disposal restrictions for hazardous wastes (40 C.F.R. Part 268); and failure to submit complete Emergency Planning and Community Right-to-Know Act (EPCRA) annual toxic release reports (42 U.S.C. § 11023 and the implementing regulations at 40 C.F.R. Part 372). Simplot agree to pay a civil penalty of $775,000 to resolve the alleged past violations of RCRA and EPCRA. In 2021, Simplot agreed to pay a $65,248 penalty for violations of federal pesticide handling and storage requirements at its storage and retail facilities in Umatilla, Oregon and Moreland, Idaho. ==Genetically modified potatoes==
