About this opportunity
The Department of Energy Office of Environmental Management has issued a Limited/Sole Source Justification Notice to extend the Legacy Management Support Services (LMSS) Indefinite Delivery Indefinite Quantity (IDIQ) contract with RSI EnTech, LLC by 12 months, extending the ordering period from 60 to 72 months through 2029. The contract provides critical environmental remediation and site management services across over 100 sites in the United States and Puerto Rico, including water treatment system upgrades, site decommissioning, five-year environmental reviews, and ongoing environmental monitoring and compliance activities. The sole source justification is based on the need to maintain operational stability and prevent disruptions to mission-critical environmental and regulatory work while ensuring uninterrupted management of former defense-related sites. The contract maintains its existing $1 billion ceiling with no additional funding required for the extension. During this 12-month extension period, the Department of Energy plans to initiate a competitive procurement process for the follow-on contract, including issuing a Request for Information/Sources Sought to identify qualified businesses for future competition.
