Status
June 2023 Quarterly Update
Residential Properties Remediation – Complete
Remediation and restoration activities are complete on all properties scheduled to be remediated under the Residential unit. Sherwin-Williams will continue to monitor the restoration of vegetation in regulated areas as required under the New Jersey Department of Environmental Protection (NJDEP) land use permit.
Route 561 Dump Site – Soils/Sediments Complete
Remediation and restoration activities are complete on all properties associated with the Route 561 Dump Site soils/sediment unit. Sherwin-Williams will continue to monitor the restoration of vegetation in regulated areas as required under the NJDEP land use permit. Groundwater associated with this unit will be monitored for the next several years.
The United States Avenue Burn Site – Remediation Underway
The EPA-selected remedy for the Burn Site includes excavation, transportation and off-site disposal of contaminated soils and stream sediments, followed by restoration activities.
Remediation activities on the west side of United States Avenue along the historic Lucaston railroad tracks are complete and restoration is underway. Remediation activities on the east side of United States Avenue, along White Sand Branch and Honey Run, are ongoing and will continue through 2023, followed by restoration activities.
The Former Manufacturing Plant (FMP) Soils – PDI / Remedial Design
The EPA-issued Record of Decision (ROD) for the FMP Soils unit includes three distinct work areas requiring different remedial approaches. The Sherwin-Williams team began an extensive EPA-approved pre-design investigation (PDI) of seven subareas within the FMP in 2022. The PDI investigation is substantially complete, and several subareas are currently in remedial design. Phased remediation is expected to begin in late 2023 or early 2024.
The vacant former warehouse buildings located at 2 and 4 Foster Avenue in Gibbsboro will be demolished to facilitate the remediation of the light non-aqueous phase liquid (LNAPL) located within and adjoining the eastern side of the FMP. Pre-demolition asbestos abatement was performed throughout May and June. Demolition activities are expected to begin in mid to late July 2023.
Waterbodies Unit – PDI
The EPA-issued ROD for the Waterbodies unit addresses contaminated sediments and soils present within Hilliards Creek and its floodplain, as well as Silver Lake, Bridgewood Lake and Kirkwood Lake.
The Sherwin-Williams team initiated the PDI of Silver Lake in Gibbsboro. Once the PDI is complete, the team will move forward with remedial design. As currently envisioned, remediation of the lakes may occur prior to remediation of the Hilliards Creek floodplain.
Former Manufacturing Plant Groundwater – Remedial Investigation
Sherwin-Williams is working with EPA to finalize the Remedial Investigation of the Groundwater unit. Once the Remedial Investigation is complete and approved, Sherwin-Williams will proceed with the Feasibility Study to evaluate alternatives for addressing groundwater contamination at the FMP.
Additional Activities
United States Avenue Sanitary Sewer Extension
Sherwin-Williams has completed the design of a sanitary sewer line extension along United States Avenue and Foster Avenue in Gibbsboro. This sewer line extension will help facilitate remediation work at and adjacent to the FMP. Construction of the sewer line extension will occur once the appropriate permits and approvals are obtained by the Borough of Gibbsboro.
Potential Kirkwood Lake Accelerated Action
Sherwin-Williams has been working cooperatively with Camden County in evaluating options for potentially accelerating the dredging of Kirkwood Lake. Sherwin-Williams and the County have retained a firm to prepare specifications and designs for dredging of the lake.
The PDI is complete and is currently under review by EPA, Camden County and Sherwin-Williams. The team continues to evaluate the feasibility of remediating Kirkwood Lake prior to completing the upstream areas.
No agreement or schedule is in place at this time for the actual dredging. Extensive design and permitting is required, which will take a year or more, before any dredging work can be performed. This work is being performed in parallel with other sections of the Waterbodies unit, by a separate project team, to ensure that any accelerated action of Kirkwood Lake does not delay efforts on upstream waterbodies.
