Proposed Plan for an Interim Amendment to the Record of Decision
The primary purpose of this Proposed Plan allows EPA and FMC to present the preferred method of cleaning up contaminant of concern (COC's) at the FMC-OU site of the Eastern Michaud Flats Superfund Site. One of the major concerns is elemental phosphorus (P4) in the soil. P4 is reactive in these conditions, allowing reactions occurring in the soil and potentially leading to the production of phosphorus acids and phosphine gas in the groundwater and soil. Other contaminants in the soil and groundwater include, but are not limited to:
For more information about human health toxicity associated with these contaminants visit the Agency for Toxic Substances and Diseases Registry http://www.atsdr.cdc.gov/toxicsubstances.html
The areas at the FMC-OU site that are undergoing remediation according to the Proposed Plan can be viewed by clicking here. The types of waste and soil materials associated with each of these areas can also be viewed here in table format by clicking here.
EPA has stated that the preferred method of cleaning up contaminants is an interim amendment to the 1998 Record of Decision (ROD). The interim ROD permits the capping of P4 waste at the FMC site and groundwater extraction system at the site boundaries. Although, the tribes are in favor of the remediation process, we propose excavating and treating the highest concentration of P4 waste in the furnace area in a safely manner. The following is a list of treatment options compiled by FMC and external sources in which FMC can perform to render the waste non-hazardous.
The Eastern Michaud Flats has been a superfund site since 1991. The primary objective for listing a contaminated site as a superfund sites is to develop a remedy or clean up of the waste on the site (remediation). The remediation process of the FMC-OU site is outlined below and the corresponding technical documents are listed on this site.
