(08/11/10) HONOLULU – The U.S.
Environmental Protection Agency has negotiated terms and ordered
cleanup of the former Chem-Wood wood treatment facility located in
the Ewa Beach area of Oahu.
The consent order directs the Estate
of James Campbell, a former property owner, and Weston Solutions
Inc., the current property owner, to grade the site and consolidate
contaminated soil under an asphalt cap. In addition, groundwater
will be monitored and treated, and restrictions placed on the
property to prevent future residential use and use of groundwater.
Weston will also fund a Trust Account to ensure that the final
remedy is completed. EPA selected the final remedy in late
2009.
"This final remedy follows up on waste
cleanup and removal work that EPA ordered in 2008,” noted
Jeff Scott, Director of the Waste Management Division for U.S.
EPA’s Pacific Southwest Region. “We’re pleased
that the cleanup by the companies will make it possible to put the
property back into productive commercial or industrial
use.”
The 2008 removal action included the
removal of all remaining contaminated debris such as treatment
vessels and chemical storage tanks. In December 2009, EPA issued
its Final Remedy Decision, which will be implemented under this
order.
The final remedy includes:
* Construction and long-term
maintenance of an asphalt concrete cap across the
site,
* Limited excavation of soil from two
adjacent properties and placement under the new cap,
* Monitoring and treatment of any
contaminated groundwater,
* Fencing and signs to restrict site
access, and
* Deed restrictions on the use of the
property and prohibiting residential reuse.
The former Chem-Wood Treatment Company
operated a wood pressure-treating operation at the site between
1975 and 1988. The operation used hazardous chemicals containing
chromium, arsenic and mineral spirits, some of which were released
to soil and have impacted groundwater. EPA first took enforcement
action at the site in 1988 and has since overseen a series of site
investigations and cleanup actions.
