Reclamation Information Sharing Environment (RISE)

A complete noise survey was performed at the Hoover Dam powerplant in Boulder City, NV in July of 2016. The survey was performed only for the Arizona side of the facility. Based on this survey, a series of engineering controls to reduce noise levels was recommended. The suggested controls were then prioritized, and in a first phase, a subset of the controls was installed. The same controls were installed on both the Arizona and the Nevada wings. A summary of installed treatments and noise reduction results is shown in Appendix A.
