The Rhode Island Supplemental Inventory (RISE) is a state-specific inventory of hazardous substances and materials located at industrial, commercial, and residential facilities in Rhode Island. It includes information on the amount, type, and location of hazardous substances and materials that are stored, manufactured, or used by a facility. RISE provides an inventory of hazardous substances and materials for the purpose of emergency planning and response activities, and it can be used to identify potential sources of contamination and potential environmental impacts. RISE consists of two types of inventories: the Hazardous Substance Inventory (CSI) and the Non-Hazardous Substance Inventory (NHS). The CSI includes substances that are classified as hazardous according to federal, state, or local regulations. The NHS includes substances that are not classified as hazardous but may present a risk to human health or the environment. RISE is maintained by the Rhode Island Department of Environmental Management (RIDE).
