In 1994, the U.S. Environmental Protection Agency (EPA) issued a Unilateral Administrative Order for Removal, instructing the facility owners to undertake cleanup operations. The LCP site was placed on the National Priorities List in 1996 (EPA Facility ID GAD09903182). The most recent removal actions were completed in 1999. A majority of the most contaminated onsite soils and waste piles have been removed from the site and placed in authorized waste disposal facilities. In addition, excavation and filling of waste basins, including brine pits adjacent to the marsh, and excavation and removal of approximately 13 acres of some of the more heavily contaminated marsh areas have been completed. The latter areas subsequently have been refilled with clean sediment and replanted with marsh grass. A contaminated groundwater aquifer located under a portion of the upland area of the site is being monitored by the EPA and the responsible parties (RPs).

In 2002, the trustees entered into a memorandum of understanding (MOU) to facilitate the coordination and cooperation of the trustees in assessing damages for injuries to natural resources. The MOU's purpose is to ensure that the trustees coordinate the natural resource damage assessment (NRDA), avoid duplication of assessment activities, coordinate development of restoration options, and recover damages from the RPs to implement restoration projects sufficient to compensate the public for harm.

Subsequently, in December 2003, the trustees and Honeywell International entered into a cooperative NRDA agreement to facilitate development of a cost-effective and efficient process for determining and quantifying injury to, destruction of, or loss of natural resources and/or services, and for determining and implementing the most appropriate approach to restore, replace, rehabilitate, or acquire the equivalent of those natural resources and/or services. The trustees and Honeywell are working together to evaluate such factors as the magnitude and extent of contamination, the toxicity of the contaminants and their effects on the natural resources of concern, and the recovery rates from the identified injuries. They will eventually evaluate and implement appropriate compensatory restoration projects.
