What changed

The Nevada Division of Environmental Protection (NDEP) is proposing amendments to Nevada Administrative Code (NAC) 519A.392, specifically regarding payments into a fund for short-term fluid management at mining operations. The proposed regulation, R145-24, seeks to increase the funding available in the Trust Fund for Short-Term Fluid Management to cover costs associated with managing process fluids at mining sites if an operator defaults, before surety bonds can be utilized. This aims to ensure the state has adequate resources to manage such situations and that the fund is replenished afterward.

NDEP is soliciting public comments on these proposed amendments through a workshop scheduled for April 9th, 2026, with both in-person and virtual attendance options. Interested parties, particularly those in the mining industry, should review the proposed regulation R145-24 and attend the workshop or submit comments to provide input on the proposed changes to funding mechanisms for environmental management at mining operations. The specific comment deadline is not explicitly stated, but the workshop date serves as a key engagement point.
