40 CFR 1611.1 - General.
(a) This part prescribes policies and procedures regarding the testimony of employees of the Chemical Safety and Hazard Investigation Board (CSB) in suits or actions for damages and criminal proceedings arising out of chemical incidents when such testimony is in an official capacity and arises out of or is related to an incident investigation. The purpose of this part is to ensure that the time of CSB employees is used only for official purposes, to avoid embroiling the CSB in controversial issues that are not related to its duties, to avoid spending public funds for non-CSB purposes, to preserve the impartiality of the CSB, and to prohibit the discovery of opinion testimony.
(b) This part does not apply to:
(1) Congressional requests or subpoenas for testimony or records;
(2) Federal court civil proceedings in which the United States is a party;
(3) Federal administrative proceedings;
(4) Employees who voluntarily testify, while on their own time or in approved leave status, as private citizens as to facts or events that are not related to the official business of the CSB. The employee must state for the record that the testimony represents the employee's own views and is not necessarily the official position of the CSB.
(c) This part only provides guidance for the internal operations of the CSB, and neither creates nor is intended to create any enforceable right or benefit against the United States.
