US EPA Anderson Calhoun Mine site

Draft periodic review report available for review

April 23, 2018 - May 23, 2018

Ecology seeks your input on the periodic review report for the US EPA Anderson Calhoun Mine site.

Former zinc, lead, and barium mining and milling operations affected approximately 92 acres of the property. Remnants of ore milling operations include a 43-acre tailings impoundment containing an estimated one million cubic yards of lead-zinc and barium tailings. Containers and drums containing hazardous and nonhazardous substances and electrical equipment containing polychlorinated biphenyls were removed and disposed. Contaminated materials in the tailings impoundment were excavated and consolidated then covered with a protective barrier and protected with access controls.  Ecology visited the site August 3, 2017, and found no indications that the cleanup has been compromised.

We conduct a periodic review at least every five years after beginning cleanup at a site, as required by the Model Toxics Control Act.  The purposes of the review are to evaluate site conditions and to ensure continued protection of human health and the environment when institutional controls are part of a cleanup. 

Ecology will review comments received during the comment period and make recommendations for suggested changes. The periodic review will become final if no significant changes are made. An additional public comment period will be held if significant changes are made.

We will hold a public meeting if 10 people request it.
