Superfund Site Profile

Current Status

The Environmental Protection Agency (EPA) and Louisiana Department of Environmental Quality (LDEQ) are working with the Potentially Responsible Parties (PRPs) to address or continue the recommendations listed in the Five Year Review (FYR). EPA is in the process of starting the next Five Year Review which is due February 11, 2016. The first FYR report was signed on February 11, 2011. Based on the information available during the first FYR, the selected remedy for the Combustion Inc. site is currently performing as intended. The remedy is considered protective because ICs are in place; therefore, there are no current or potential exposures. The recommendations and follow-up actions identified in this FYR process should be addressed or continued for long-term remedy protectiveness of human health and the environment until remedial action objectives are met.
