The U.S. Environmental Protection Agency fined Asarco LLC $30,900 for using buildings contaminated with PCBs and improper management of PCB waste at its copper smelter in Hayden.
The company will also spend $115,714 to reduce PCBs at the smelter, the EPA announced Thursday.
The violations stemmed from a 2011 inspection in which the EPA found two buildings contaminated with PCBs. Asarco employees continued to use the buildings, a violation of the federal Toxic Substances Control Act, according to the EPA.
As part of the agreement, Asarco will replace three PCB transformers at the smelter, reducing future risk of exposure to workers and the environment, according to the EPA.
