Mr. Hall has served as President and General Manager of Lockheed Martin Hanford Corporation where he managed the Tank Waste Remediation Project. This project, which included storage, characterization, and future retrieval systems of over 55 million gallons of both high and low level radioactive waste in 177 underground storage tanks located in Richland Washington, was reengineered and set on a success path under his leadership. His responsibilities at Hanford also included site wide Information Resource Management and Systems Engineering functions supporting fifteen contractors with a workforce of over 8000 people.

Previous to the Hanford project, Mr. Hall was Vice President of Lockheed Martin Environmental Management and Enrichment (EMER) for five DOE sites located in 3 states (Tennessee, Kentucky, and Ohio) with a work force of approximately 7500 people and an annual operating budget of over $1 billion. Under his leadership, Environmental cleanup programs were initiated and enhanced in Groundwater Treatment and Remediation, Radiological and Chemical burial ground recovery and disposition, startup and operation of the first US-DOE TSCA incinerator and High Level and Low Level Nuclear Waste stabilization.

In collaboration with DOE, Mr. Hall led a first of its kind small business outsourcing program for over $200 million per year of environmental restoration work within East Tennessee. During his tenure, the Oak Ridge Gaseous Diffusion Plant received multiple awards for excellence including Al Gore’s Hammer Award for cost savings and a DOE Tiger Team rating of 89%. Under Mr. Hall’s leadership, the EMER program grew from $250M program to a $900M funding level. This accelerated all five sites towards Environmental compliance agreements and clean up of the DOE Gaseous Diffusion legacy waste.

From 1960 – 1990, Mr. Hall participated in the development of weapon systems and space programs for Martin Marietta of Orlando, FL. His Aerospace experience has included the design, test, production and fielding of numerous electronic and missile programs including space launched systems.

In 1986 he led the Martin Marietta Corporation in achieving regulatory compliance in its Baltimore, MD., Cape Canaveral, Orlando and Tennessee Operations. This effort involved designing, implementing or converting all Martin Marietta chemical processing operations and production operations into EPA and state of the art compliance. It also involved establishing remediation programs for burial grounds and groundwater cleanup. Mr. Hall’s Aerospace experience includes the THOR-Delta Space launch Systems, Pershing deployment, Copperhead, Hellfire, LANTIRN, CNCE, and Patriot systems. He provided the technical and project leadership to transform the Orlando Production Operations into a statistically controlled (SPC) Zero Defect Enterprise. These operations were granted one of the first Audit Free Status by DCAA.
