Director Emeritus L&L Associates, Inc.Executive Vice President and COO Work 4448 Tidewater Drive Orlando FL 32812 United States

Mr. Hall has many years of experience in technology development, program management, systems integration, process development, systems engineering, environmental restoration of nuclear chemical facilities and waste management. He is currently Executive Vice President and COO of L&L Associates, Inc. L&L Associates Inc. is headquartered in Orlando Florida and has expertise in developing successful program management and program strategies to accomplish complex technical and programmatic missions for the Department of Energy and the Department of Defense

In his capacity of Executive Vice President of L&L Associates, Inc. Mr. Hall has served as interim Chief Operating Officer for Kaiser Hill Company at the Rocky Flats site from April 2001 until January 2002. In this position, his leadership helped to restore a positive working relationship with the DOE customer, raise the ESH&Q level of performance, and improve the cost and schedule earned value from a negative to a positive trend before turning his position over to his successor.

Mr. Hall has advised and assisted the DOE in technical baseline assessments of complex wide programs such as the WTP Best and Brightest External Pretreatment Flow sheet Review, the Bulk Vit External Review, and continues to serve as a technical advisor to the Department.

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. Under Mr. Hall’s leadership, Martin Marietta developed and initiated a unique chemically controlled Zero Discharge System for environmentally compliant state of the art ultra-micro circuit development and processing. 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.

Awards and Honors

Mr. Hall has received numerous awards, including a Hammer Award for enhanced work planning for Lockheed Martin Hanford. DOE-RL gave special recognition to Mr. Hall’s company at Hanford. His experience in both DOE and DoD facilities spans four EPA regions in the US. He is the recipient of seven Total Quality Management Awards (TQM) presented by the governor of Tennessee for work at the K25 facility. He has received the Hedgepeth Award for environmental conservation in the state of Florida. Mr. Hall has extensive experience in Leadership, Project Management and Programmatic Technical Proposal development. Mr. Hall has been an inspirational leader and mentor to many of the key personnel leaders in the DOE enterprise.
