June 2022 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 unit. Sherwin-Williams is currently working on administrative documents and filings to close-out soil and sediment remediation under this project unit.

Sherwin-Williams will continue to monitor the restoration of vegetation in regulated areas as required under the NJDEP land use permit. Groundwater and surface water associated with this unit will be monitored for the next several years.

The United States Avenue Burn Site – Remediation to Begin in Fall 2022
Sherwin-Williams submitted the 100% design document to EPA on June 3, 2022. Remediation and restoration of the Burn Site unit is expected to begin in early fall 2022.

The Former Manufacturing Plant (FMP) Soils – Pre-Design Investigation
The EPA-approved remedy 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 in February 2022. The pre-design and remedial design phases for each area are expected to extend over multiple years.

Waterbodies Unit – Record of Decision (ROD)
On October 1, 2021, EPA released a ROD for the Waterbodies unit. This ROD describes the selected remedy to address contaminated soil and sediment present within Hilliards Creek and its floodplain, as well as Silver Lake, Bridgewood Lake and Kirkwood Lake located in Gibbsboro and Voorhees.

Pre-design investigation activities and planning for the Waterbodies Unit will begin once a modification to the existing Consent Decree is finalized and Sherwin-Williams has legal authorization to perform the work.

Former Manufacturing Plant Groundwater – Remedial Investigationc
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 and Milestones

Former Manufacturing Plant Property
Sherwin-Williams recently acquired a majority of the Paint Works Corporate Center property in Gibbsboro from Brandywine Operating Partnership. The property is the site of the former Lucas Paints and Sherwin-Williams manufacturing plant and is part of the Sherwin-Williams/Hilliards Creek Superfund Site. This acquisition on the part of Sherwin-Williams is an important step in ensuring that the Company can implement the EPA-approved remedies for the FMP and other project units in a timely and efficient manner while minimizing disruptions to tenants and the community.

United States Avenue Sanitary Sewer Extension
Sherwin-Williams is working on the design of a sanitary sewer line extension along United States 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 design is complete, and the appropriate permits and approvals are obtained by the Borough of Gibbsboro.

Kirkwood Lake Accelerated Action
Sherwin-Williams has been working cooperatively with Camden County in evaluating options for accelerating the dredging of Kirkwood Lake. Sherwin-Williams and the County recently selected a firm to prepare specifications and designs for dredging of the lake. No agreement or schedule is in place at this time for the actual dredging. The work will be performed in parallel with other sections of the Waterbodies unit, by a separate project team, to ensure that an accelerated dredge of Kirkwood Lake does not delay efforts on upstream waterbodies.

Sherwin-Williams Project Team
Sherwin-Williams long-time remediation director, Mary Lou Capichioni, recently retired from the Company. Jim Schenker, project manager for the Burn Site, is now Director of Remediation for Sherwin-Williams. Jill Edwards, formerly the program director for Weston Solutions, has been hired by Sherwin-Williams as a Senior Project Manager and will be located in the Gibbsboro field office. The combination of Jim’s leadership and Jill’s daily presence in the Gibbsboro office will help ensure a seamless transition and continuation of the progress Sherwin-Williams achieved under Mary Lou’s direction.
