The U.S. Nuclear Regulatory Commission (NRC) is considering approval of a premobilization notification (PMN) under source materials license SUA-1605, which the NRC issued to DISA Technologies, Inc. (DISA) in 2025 for the operation of its high-pressure slurry ablation (HPSA) technology to remediate abandoned uranium mine (AUM) waste. If the NRC approves the PMN, DISA could conduct HPSA operations at the Mary Ann AUM waste pile site (Mary Ann site) in Montrose County, Colorado. The NRC staff is issuing an environmental assessment (EA) and finding of no significant impact (FONSI) associated with the proposed approval. This EA tiers from the NRC staff's 2025 generic EA for the license issuance and the 2026 generic EA for the use of flocculant in the HPSA process.
