&EPA United States Environmental Protectior Agency PETRO-PROCESSORS of LOUSIANA, INC East Baton Rouge, Louisiana April 2012 656345 This Fact Sheet will tell you about... • Site History • Enhance Plume Attenuation • Current Actions • Future Plans • Community Involvement Site History The PPI site was originally used as a depository for various petrochemical waste products during the 1960s and the 1970s. In July 1980, the U.S. Justice Department filed suit against PPI and Industry Defendants, alleging that they disposed wastes at this facility. On February 16, 1984, the U.S. Federal District Court, Middle District of Louisiana issued an order approving a Consent Decree for a remedial action. • Initial Remedy The initial response action specified the design of a vault and the complete closure of the site by excavating, solidifying and land-filling all visible waste along with recovery of deeper waste and treatment by incineration. After initiating this response, air monitoring demonstrated releases of volatile organics to the air above the previously agreed fence line concentrations. • Final Remedy A supplemental investigation was conducted and a Supplemental Remedial Action Plan was approved. This plan provided for hydraulic containment and recovery, coupled with incineration. Through additional investigations, the remedial plans were expanded or modified to protect potential threats to human health and the environment. These plans were implemented and included: o Placement of a protective covering over the original open pits (known as the Brooklawn and Scenic Sites) o Source reduction by pumping treatment and removal of contaminated groundwater o Protective fill over Bayou Baton Rouge distributaries near the Brooklawn PPI location (known as the Bayou/adjacent wetland area) o Monitoring that natural attenuation takes place o Sampling the groundwater sediments, biota and the air to monitor the effectiveness of the actions o Conducting future modeling and inspection activities o Continue updating of groundwater modeling investigations o Placing administrative controls to limit access to the site. These actions were implemented and a long term monitoring program was initiated. In July 2003, the site received Construction Complete status. Five-Year Reviews had been completed on December 22, 2005, and December 28, 2010. These reviews found that the remedy implemented remains protective of public health and the environment. Currently the site is in the operation and maintenance phase, while further modeling, monitoring, and inspection activities continue to be implemented to ensure protection of human health and the environment. Enhance Attenuation (EA) An investigation was initiated in 2003 to assess the fate and transport of dissolved contaminants from the Scenic site and update the transport model. The investigation included further evaluation of the shallow groundwater (the +20 MSL zone) where monitoring found some contaminants not degrading as fast as predicted. Enhance plume attenuation is a viable remedial alternative to accelerate compliance with the groundwater remedial objectives. Therefore the shallow groundwater was further investigated in 2004, 2005 and 2006 to define the edges of this zone (the +20 MSL zone). Once identified, pilot testing for EA was initiated at the Scenic site in 2009. After successful testing, construction of two near source treatment zones was proposed in 2010 to augment the natural attenuation process. These treatment zones were built and EA activities were initiated with the injection of molasses to enhance biological activity in 2011. ------- Current Actions EA is ongoing at the near source (Scenic) treatment zones and plans to investigate the effects of this process at the end of the plume are underway. Early this year the installation of monitoring, injection and extraction wells was completed at the distal end, on property of the Louisiana State Police. Pilot testing of EA will be conducted during the next 12 months, and if successful, full implementation of an EA distal treatment zone is planned. Future Plans Annual Long Term Monitoring of the implemented actions at the Brooklawn, Scenic and Bayou/wetland area continues. With the implementation of EA at the near source treatment zones, monitoring continues as well as monitoring of the EA pilot testing process at the distal end of the plume. Future injections of substrate, molasses, will be injected as needed to support the enhanced biological activity. Since PPI wastes remain onsite at the Petro-Processors of Louisiana, Inc. Site, EPA will perform site reviews at a minimum of every five years to determine if the cleanup at the site is still protecting public heath and the environment. EPA and the State will continue to monitor the site between reviews. If at any time you have concerns or questions about the site, let EPA know. You can contact EPA by calling 800.533.3508 (toll-free). Community Involvement We want to hear from you. EPA will consider any information or concerns that you may have about the site. If you are familiar with the site, you may know things that can help us. Here are some examples: • Broken fences, unusual odors, illegal dumping, or other problems; • Buildings or land being used in new ways around the site; • Any unusual activities at the site such as vandalism or trespassing; and • How the cleanup at the site has helped the area. The public may contact the EPA or local state officials with any questions or concerns they may have. For More Information, Please contact...
