This bill, titled the "Stop NOAA Closures Act," establishes a moratorium on actions that would limit access to facilities of the National Oceanic and Atmospheric Administration (NOAA). Specifically, it prohibits the Secretary of Commerce, the NOAA Administrator, or the Administrator of General Services from closing, suspending, terminating leases of, ceasing construction of, consolidating, or otherwise imposing any new limitation on access to NOAA facilities. This broad prohibition aims to prevent disruptions to NOAA's operations and infrastructure. An exception to this moratorium allows for temporary actions in response to emergencies that pose an immediate threat to the health or safety of NOAA personnel. The moratorium is not indefinite; it will cease to be effective 180 days after a comprehensive report is submitted to specific congressional committees. This report, due no earlier than January 21, 2029, must jointly outline and justify the process for selecting any facility for closure or other limiting actions, including an analysis of criteria and a detailed cost-benefit analysis . The required cost-benefit analysis must consider anticipated savings, the costs associated with replacing lost services, and the anticipated impact on NOAA's overall services. Following the cessation of the initial moratorium, the bill mandates that any future actions to close, suspend, or limit access to NOAA facilities will require a 30-day prior notification. This notification must also be a joint report to Congress, detailing the justification and analysis for such decisions, ensuring continued oversight and transparency.
