The Rhode Island Department of Environmental Management (RIDEM) Office of Land Revitalization and Sustainable Materials Management (LRSMM) encourages post-closure use of landfills as long as the use will not compromise the environmental protection afforded by the landfill cap and closure. While capped and closed landfills may not be appropriate sites for residential or commercial development, they are more suitable for the installation of a photovoltaic (PV) solar array, which generate renewable energy and may provide income for landfill owners. This page includes LRSMM’s requirements, regulations, the process for approving and additional resources needed to install solar.


In January of 2021 LRSMM revised the Solid Waste Regulation No. 2 (250-RICR-140-05-2). Specifically, Section 2.1.9(J) - Installation of Solar Panels on Landfills was added. To better understand this new Section, the following Guidance Document was created.
