Two Valley companies have agreed to pay fines to settle environmental cases.
Arizona Public Service Co. will pay $200,000 to settle allegations of air and hazardous waste violations at a northern Arizona power plant, state officials said.
The Department of Environmental Quality and Attorney General Terry Goddard said DEQ inspectors found that the Cholla Power Plant near Joseph City failed to properly store and dispose of hazardous waste in 2001.
DEQ inspectors also found violations of the plant’s air quality permit, including improper burning of paint, paint chips and antifreeze in a boiler and burning of asbestos panels during fire training exercises, the officials said.
APS spokeswoman Sheri Foote said the company disputes the allegations but decided to settle. ‘‘APS takes very seriously its role as a corporate leader and environmental steward in Arizona,’’ Foote said.
The settlement is still subject to court approval.
In the second case, the U. S. Environmental Protection Agency has fined a Tempe company $17,000 for violating air emissions standards related to the use of a toxic solvent in degreasing operations. Also, the company agreed to spend an additional $65,000 for improvements that will eliminate releases of the hazardous material.
Triumph Corp., 2130 S. Industrial Park Ave., agreed to stop using trichloroethylene, or TCE, in its degreasing operations and begin using npropyl bromide, which is not classified as a hazardous air pollutant, the EPA said.
The actions will ultimately reduce the company’s toxic air emissions by an average of 5.25 tons a year, the agency said.
