Gary S. Kephart, CIH, CHP, CSP, CHMM, RRPT, passed away on Jan. 14, 2018. He was 64. Gary had more than 35 years’ experience in environmental, health, and safety and radiation protection involving the operation, maintenance, and demolition of radiological and nuclear facilities. He began his career in the nuclear industry in 1976 with a unique combination of hands-on involvement, professional credentials, and team-building success. Gary served on the Tennessee Valley Local Section Board of Directors from 2012 until 2018, and was president in 2016–2017.

Gary was an experienced EHS and radiation protection program manager and supervisor with experience in radiological facility deactivation, decontamination, decommissioning, and environmental restoration. He worked as the EHS manager at the U.S. Department of Energy Portsmouth Gaseous Diffusion Plant in Ohio for four years and served as the EHS supervisor for the chemical defueling of the Molten Salt Reactor Experiment at the DOE Oak Ridge National Laboratory in Tennessee. He also supervised the removal of asbestos from the 1.1-million-square-foot K-27 former uranium processing facility at the DOE East Tennessee Technology Park (ETTP). He was also the contract-designated industrial hygiene subject matter expert for the $2.2 billion clean-up project at ETTP involving more than 1,200 workers.

Gary enjoyed helping many organizations on both the national and local levels. He supported the Health Physics Society for more than 25 years and the National Registry of Radiation Protection Technologists for more than three decades. In 2002, NRRPT recognized Gary’s long-term dedication and outstanding support to the organization with the Arthur F. Humm, Jr.  Award.

Gary continually encouraged people to pursue further certifications, and dozens of coworkers can attest to his positive influence on their careers. His wit, positive influence, and organizational service will be greatly missed by all who had the privilege to work with him.
