Staying Informed and Involved
The removal actions reduced any potential exposures to both human health and the environment from the toxins contained within the on-site tanks. The 2003 remedial action removed all remaining risks for exposure by removing the tank sludges and the contaminated soil hot spot, as well as all on-site structures. There are no long-term operation and maintenance requirements for the site since all contaminated wastes and materials have been removed from the site. In addition, an evaluation of the ground monitoring results obtained during the remedial action indicates no further action is needed regarding ground water at the site. Since the site no longer presents an unacceptable risk to human health and the environment because of the implemented remedy, institutional controls are not needed at the site.
Are there risks at the site now?
Risks and pathways addressed by the cleanup include health risks from people ingesting or touching contaminants in soils, structures and debris.
Emergency Response and Removal Program
Cleanup has also included removal actions, or short-term cleanups, to address immediate threats to human health and the environment. Removal actions from 1998 to 1999 included sampling, operating heavy equipment, cleaning tanks, decontaminating equipment, conducting air monitoring, treating and discharging surface water, and arranging for off-site disposal of tank materials. Materials disposed of off site included two Portafeed units, 24 laboratory packs, two overpacked drums, 142 55-gallon metal drums, 824,300 gallons of tank material by barge and 26,000 gallons of tank material by truck.
The 10-acre Mallard Bay Landing Bulk Plant (MBLP) Superfund site is located in Cameron Parish, northeast of Grand Chenier, Louisiana. The site consists of two 5-acre areas separated by Talen’s Marine, an active marina and dock. From early 1980 through 1983, the MBLP facility operated as a crude oil refinery. In 1987, the owners filed for bankruptcy and the facility closed. In 1993, an inspection revealed oily liquids and sludges in tanks and other environmental concerns. In 1998 and 1999, EPA began cleanup activities, including the removal and off-site disposal of oil and waste material from on-site tanks. In 2000, EPA added the site to the Superfund program’s National Priorities List (NPL) to address remaining site contamination. In 2003 and 2004, EPA removed all remaining tank sludges, contaminated soil and structures. EPA deleted the site from the NPL in 2005. Cleanup levels allow a full range of uses at the site. Currently, Talen’s Marine is using the site as a staging and storage area.
