This chapter provides a summary of HCA authorities based on statute, FAR, DEAR, and DOE
Orders. It serves as a general guide to the authorities that may be conferred via a formal
delegation of HCA authority from the Department of Energy Senior Procurement Executive.
This formal delegation prescribes the specific source and scope of the HCA’s authority with
respect to that individual’s contracting actions. HCA delegations are unique and specific to the
individual program or field activity, based on mission, workload, performance and other factors
considered by the DOE Senior Procurement Executive.
