Mineta's directive went into effect when it was signed Jan. 5. But it was not publicized by the department until it was published in the Jan. 18 issue of the Federal Register. It says information that agency officials regard as being sensitive involving "all modes of transportation" will be exempted from release under the Freedom of Information Act, or during court proceedings on civil suits.
In response to a reporter's question, the department issued a statement saying "information previously available to the public, such as environmental impact statements and safety statistics, will continue to be accessible according to laws protecting public access."
