The Department of Transportation, with the concurrence of the Office of Government Ethics (OGE), is issuing regulations for DOT employees that supplement the Standards of Ethical Conduct for Employees of the Executive Branch (Standards) issued by OGE. These regulations are a necessary supplement to the executive branch-wide Standards because they address ethics matters unique to DOT. In particular, they specify agency designees authorized to make determinations and grant approvals under the Standards, designate DOT components as separate agencies for purposes, in part, of the gift rules contained in the Standards, and prohibit employees of the Federal Railroad Administration and the Federal Aviation Administration, which are two administrations within DOT, from having certain financial interests.
