The facility has been stabilized several times to contain and mitigate any off-site threat of release of hazardous substances. ADEQ representatives have assisted in monitoring the conditions of the site and working with EPA personnel.
OSC Adams was activated to respond and monitor the removal of a significant volume of hazardous substances on-site. The bank that controls the securities for the facility and all the contents present sold a large volume of the hazardous substances to a vendor. The deadline for the vendor to remove the chemicals was April 15, 2011 at midnight. OSC Adams mobilized to the facility on April 10, 2011 to oversee and monitor the removal and ensure no hazardous substances were released into the environment. ADEQ representative Gates also mobilized to Site to support the response effort.
The bank released the hazardous substances to the EPA shortly after the April response. Planning was conducted between EPA, ADEQ, and EPA contractors to begin the removal of the remaining hazardous substances on-Site.
EPA and EPA contractors mobilized to the Site on July 13, 2011 to begin the removal action of the remainder of the hazardous substances at the abandoned facility. Updates will be posted to this website as the course of the removal action is conducted. The response effort is expected to be completed prior to October 1, 2011.
