Montezuma Creek Stability Evaluation at Site of Former Monticello Tailings Pile

PDF Version Also Available for Download.

Description

This report documents the results of an evaluation of stream stability for Montezuma Creek downstream of the former uranium and vanadium millsite at Monticello, Utah. The work was performed by personnel from Oak Ridge National Laboratory's (ORNL's) Environmental Technology Section (ETS). ORNL/ETS was the Independent Verification Contractor (IVC) for the Monticello projects, and it established independent verification strategies that provided the U.S. Department of Energy (DOE) with a third-party assessment of whether remedial action had effectively reduced levels of contamination and whether supporting documentation that described the remediation was adequate. The DOE regulation 10 CFR 1022, which implements Executive Orders ... continued below

Description

This report documents the results of an evaluation of stream stability for Montezuma Creek downstream of the former uranium and vanadium millsite at Monticello, Utah. The work was performed by personnel from Oak Ridge National Laboratory's (ORNL's) Environmental Technology Section (ETS). ORNL/ETS was the Independent Verification Contractor (IVC) for the Monticello projects, and it established independent verification strategies that provided the U.S. Department of Energy (DOE) with a third-party assessment of whether remedial action had effectively reduced levels of contamination and whether supporting documentation that described the remediation was adequate. The DOE regulation 10 CFR 1022, which implements Executive Orders 11988 and 11990 for the protection of wetlands and floodplains, provided the regulatory rationale for the activity. This report documents both the impact of millsite remedial activities and postremediation conditions of Montezuma Creek. The scientific rationale for the stream survey was that conventional engineering practices do not adequately account for varying hydrologic regimes nor do they address the entire riparian zone as an interrelated unit. As a result, modifications to streams consistently cause damage to the environment by increasing erosion and sedimentation. Field activities included the establishment of permanent cross sections and periodic measurements and surveys of physical characteristics. The data demonstrated an increase in downstream stream bank erosion when activities at the millsite were greatest. Note, however, that agricultural practices have also contributed to erosion and bank instability. Nevertheless, an increase in fine sediment and bank recession were correlated to the construction. In addition, the project documented the failure of best management practices such as silt fences, to control sediment loss. Furthermore, conventional engineering designs were used to reroute Montezuma Creek, an action that will require increased maintenance when compared to a natural channel. Although these latter actions remain the most common practices, it is recommended that DOE apply geomorphic designs at future sites.
