Association of State and Territorial Solid Waste Management Officials; Denial of Petition for Rulemaking
The U.S. Nuclear Regulatory Commission (NRC) is denying a petition for rulemaking (PRM-32-6) submitted by the Association of State and Territorial Solid Waste Management Officials (ASTSWMO or the petitioner). The ASTSWMO requested that the NRC amend its regulations to improve the labeling and accountability of tritium exit signs. The ASTSWMO believes the majority of unaccounted tritium exit signs are disposed of in solid waste landfills where they become potential sources of groundwater and surface water contamination. The ASTSWMO requested that the NRC revise its regulations or guidance to require that: the labeling be in several locations on the sign and printed with larger font; an expiration date should be distinctly legible to a fire or building inspector without taking down the sign; and the radiation trefoil should be displayed on the front and back of advertisements. Although not a specific request for rulemaking, the petitioner recommended that a national collection effort with distinct milestones and goals be undertaken to consolidate all expired and disused tritium exit signs. The petitioner requested that the NRC organize a meeting with ASTSWMO and all interested stakeholders to set a new path forward on this issue. The NRC is denying PRM-32-6 for the reasons stated in this document.
