EPA accepts fine from Cheyenne firm

Cheyenne, WY – The U.S. Environmental Protection Agency says a company with a chemical plant in Cheyenne has agreed to pay more than $110,000 for alleged Clean Air Act violations.
The EPA announced Monday that the settlement also requires Dyno
Nobel, Inc., to improve maintenance and internal auditing of
equipment used to store and process hazardous chemicals at the
Cheyenne plant.
The company also has agreed to improve documentation of training
for employees who work with hazardous chemicals at the plant.
Dyno Nobel is a supplier of industrial explosives. The company
stores large quantities of hazardous substances including ammonia
and chlorine at the Cheyenne plant.
The settlement results from a compliance inspection at the plant
last November.
