NV5 provided nearly a decade of industrial hygiene support to “tank farm” operations at the U.S. Department of Energy Hanford Site. The Hanford tank farms comprise 177 underground tanks storing 56 million gallons of radioactive and chemical waste.
NV5 staff developed industrial hygiene programs and technical documents on exposure assessment, instrumentation, respiratory protection, and chemical protective clothing associated with maintenance and operations during waste retrieval activities. The technical aspects considered more than 1,800 chemicals, as well as beryllium, asbestos, noise, and other non-radiological hazards. We developed approximately 25 implementing procedures on work area screening, personal monitoring, exposure assessments, and area monitoring using state of the art instruments and calibration.
NV5 also provided industrial hygiene expertise to resolve complex chemical vapor exposure issues, including developing and implementing corrective actions to address a NIOSH Health Hazard Evaluation. We developed a detailed Exposure Assessment Strategy and revised the existing Health and Safety Plan and Safety Policy. One year after our recommendations were implemented, the Director of Environment, Safety and Quality for DOE’s Office of River Protection identified “no findings” and noted “a number of areas where the CH2M HILL program elements significantly exceed regulatory requirements.”
