Trimble, Director Natural Resources and Environment, Testimony Before the Subcommittee on Strategic Forces, Committee on Armed Services, U.S. Senate [open pdf - 312KB]
"DOE's [Department of Energy] NNSA [National Nuclear Security Administration] is responsible for managing the nuclear weapon stockpile and supporting nuclear nonproliferation efforts. NNSA executes its missions at eight sites that make up the nuclear security enterprise. DOE's EM's [Office of Environmental Management] mission includes decontaminating and decommissioning facilities that are contaminated from decades of nuclear weapons production and nuclear energy research. DOE has made progress, but GAO [Government Accountability Office] continues to identify challenges across the nuclear security enterprise, including with major projects' cost and schedule delays. With NNSA and EM proposing to spend tens of billions of dollars to modernize the nuclear security enterprise, it is important to ensure that scarce resources are spent in an effective and efficient manner. This testimony discusses DOE's (1) ongoing challenges in nuclear security modernization, (2) growing cost of environmental liabilities, and (3) nonproliferation accomplishments and long-term planning challenges. GAO's statement is based mainly on information from 11 prior GAO reports issued from February 2015 to February 2016, as well as on ongoing work on (1) DOE's plans to develop a high-level waste repository and (2) environmental liabilities. That work included reviewing agency documents and interviewing agency officials. GAO is not making any new recommendations. DOE continues to act on the numerous recommendations GAO has made in these areas. GAO will continue to monitor DOE's implementation of these recommendations."
