In this decision, the Surface Transportation Board (the Board) modifies its regulations to permit, subject to disclosure requirements, ex parte communications in informal rulemaking proceedings. The Board also adopts other changes to its ex parte rules that would clarify and update when and how interested persons may communicate informally with the Board regarding pending proceedings other than rulemakings. The intent of the modified regulations is to enhance the Board's ability to make informed decisions through increased stakeholder communications while ensuring that the Board's record-building process in rulemaking proceedings remains transparent and fair.
