Umetco Minerals Corporation; Gas Hills East Site

The U.S. Nuclear Regulatory Commission (NRC) has received an application from Umetco Minerals Corporation for amendment of Materials License No. SUA-648 to modify the ground water monitoring program at Umetco's Gas Hills East site in Fremont and Natrona counties, Wyoming. The amendment would increase the number of wells in the ground water monitoring program, change the sampling period and parameters, change the reporting period for ground water monitoring reports and establish the ground water monitoring program as a stand-alone document, rather than an appendix in Umetco's Alternate Concentration Limit application.
