Residential Properties Remediation
Remediation and restoration activities are complete on 30 residential properties located in Gibbsboro and Voorhees. In addition, Sherwin-Williams has completed remediation on two residential properties located along Hilliards Creek in Gibbsboro. Restoration of these two properties, and a portion of Hilliards Creek, is nearly complete. Work is expected to be completed this spring. Remediation and restoration work on residential properties along Kirkwood Lake in Voorhees will continue through 2021.

Route 561 Dump Site
Remediation and restoration activities are complete on commercial and open space properties along Route 561 in Gibbsboro. Remediation of areas along White Sand Branch between Route 561 and Berlin Road is underway. Activities along White Sand Branch will continue through 2021. All work under the Dump Site unit should be completed this year.

The United States Avenue Burn Site
Sherwin-Williams has completed the pre-design investigation at the Burn Site and associated properties, and is moving forward with preparation of the remedial design documents. Areas within the Burn Site are being used for the short-term staging of equipment and soils during the remediation of the Route 561 Dump Site and White Sand Branch. These areas will later be remediated under the Burn Site unit.

Former Manufacturing Plant (FMP) Soils
The Sherwin-Williams team has initiated planning efforts for the pre-design investigation phase which is required to prepare the engineering, design and construction documents. Pre-design investigation activities will begin once a modification to the existing Consent Decree is finalized and Sherwin-Williams has legal authorization to perform the work. The public comment period on the Consent Decree modification closed on March 1, 2021 and a motion to enter the Consent Decree modification was filed in federal court on March 11, 2021.

In order to facilitate remediation work at and adjacent to the FMP, Sherwin-Williams will extend a segment of the sanitary sewer line to certain residential properties located on United States Avenue in Gibbsboro. Design of the sewer line extension is underway.

Waterbodies Unit
Environmental investigations and risk assessments related to Hilliards Creek and the associated lakes are complete. Sherwin-Williams submitted a final Feasibility Study (FS) to EPA which evaluates the remediation alternatives for Hilliards Creek and its floodplain, as well as Silver Lake, Bridgewood Lake and Kirkwood Lake. The FS was thoroughly reviewed by EPA Region 2, the EPA Remedy Review Board, and EPA Headquarters and was approved on February 23, 2021. EPA is expected to release a Proposed Remedial Action Plan (PRAP) for the Waterbodies Unit in the next month or so. EPA will host a virtual public meeting to explain the proposed plan and obtain input from the community.

Sherwin-Williams continues to work cooperatively with Camden County which is pursuing options for accelerating the dredging of Kirkwood Lake.

Former Manufacturing Plant Groundwater
Sherwin-Williams is working with EPA to finalize the Remedial Investigation of the Groundwater unit. Once the Remedial Investigation Report is finalized and approved, Sherwin-Williams will proceed with the Feasibility Study to evaluate alternatives for addressing groundwater contamination at the FMP.
