The Former Manufacturing Plant (FMP) Soils project unit includes the former paint manufacturing facility and the headwaters of Hilliards Creek from the outflow of Silver Lake to West Clementon Road in Gibbsboro.
The FMP was used for the manufacturing of paint and varnishes from 1851 to 1930 by John Lucas & Company, and continued operations under The Sherwin-Williams Company from 1930 until 1978. Over the course of this history, areas of the FMP were used for manufacturing operations, material storage and waste handling.
The Remedial Investigation and Feasibility Study for the FMP Soils unit are complete and EPA released its final Record of Decision (ROD) on August 10, 2020.
The EPA-selected remedy addresses contaminated soils at the FMP, sediments in the portion of Hilliards Creek adjacent to the FMP, as well as an area of light non-aqueous phase liquid (LNAPL) contamination within and adjoining the eastern side of the FMP.
The EPA-selected remedy includes the following components:
- Excavation, transportation and off-site disposal of contaminated soils and sediments;
- Backfilling of excavated areas with clean fill and top soil, as required;
- In-kind replacement of property amenities disturbed during construction;
- Replanting of vegetation and restoration of the stream corridor and associated wetlands;
- Enhanced bio-remediation, including nutrient injections, as well as passive and active recovery systems to address LNAPL contamination; and,
- Placement of institutional controls and deed restrictions to limit exposures to residual contamination remaining at depth on certain properties, as agreed to with the property owner.
Pre-design investigation activities will begin once Sherwin-Williams and EPA execute a Consent Decree which provides legal authorization to begin work. Pre-design and remedial design activities are expected to begin in 2021.
