Title	Concurrent Report
Event Description	The following information was provided by the licensee via phone and email: A 24-hour report was made to New Mexico Environment Department in accordance with discharge permit condition 30 and New Mexico Administrative Code (NMAC) 20.6.2.1203 on 10/15/2025 for an unauthorized discharge. This is a concurrent report in accordance with 10 CFR 70 Appendix A(c). On 10/14/2025, work to empty laboratory rinse water into an approved discharge route commenced in accordance with procedure. This routes the rinse water to a lined retention pond, as approved in Urenco USA's discharge permit. During transfer of the rinse water, it was identified that the rinse water was not being put into the intended location. It was determined that it was being put into a cement vault for a domestic water flowmeter. The contents of the tote are approximately 330 gallons of rinse waster from non-radiological labware for reagent preparation from the chemistry laboratory, containing primarily deionized water with dilute acids, detergents, and neutralized with sodium bicarbonate. It was analyzed to be within allowable limits for uranium concentration and pH in accordance with the discharge permit and NMAC 20.6.2.3103, prior to removal from the laboratory. This event has been put into the corrective action program and corrective actions are ongoing.
