Next steps

We will review all comments received during the comment period and update the periodic review, if needed. If no significant changes are made, the periodic review will become final. If significant changes are made, we will hold an additional public comment period. We will hold an online public meeting if 10 or more people request one.​​

Site history and cleanup

The LeRoi Smelter operated intermittently from 1896 to 1909, processing various metals, including lead. In 2004, the U.S. Environmental Protection Agency consolidated all scrap metal for recycling, consolidated and capped contaminated soil with a protective barrier, and properly disposed of hazardous materials off-site. Access controls and an environmental covenant limit public access and protect the integrity of the cleanup actions.

About periodic reviews

Periodic reviews are required when institutional controls are required at a site. Institutional controls can be fences, signs, or restrictions on how the property is used. Ecology conducts reviews to make sure the controls remain effective and the cleanup still protects human health and the environment. We conduct periodic reviews about every five years.
