UNITED STATES DISTRICT JUDGE CHARLES R. RICHEY
Plaintiff, T.V. Tower, Inc., was the owner of a 1,484 foot guyed television broadcasting tower located near Lake Pickett, Orange County, State of Florida. In the course of its business, plaintiff leased a space on the tall tower to Florida Central East Coast Educational Television, Inc., ("Channel 24"). Channel 24 employed Jampro Antenna Company ("Jampro") to design and install an antenna and a coaxial line on the tall tower. On or about June 8, 1973, while Jampro and its agent, Tower Maintenance of Florida, Inc., ("Tower Maintenance"), were installing Channel 24's coaxial line on the tall tower, the tall tower collapsed. As a result of the accident, two employees of Tower Maintenance were killed, and the plaintiff suffered extensive damage to its property and business.
Following the collapse of the plaintiff's tall tower, plaintiff began to investigate the causes of the accident. During that investigation, plaintiff was approached by representatives of the Occupational Safety and Health Administration (OSHA) for information about the tower's collapse. In the course of its investigation, OSHA interviewed several witnesses, including employees of the companies which were employed to install the Channel 24 antenna and coaxial line.
Thereafter, plaintiff instituted suit in the Circuit Court of the Ninth Judicial Circuit in and for Orange County, Florida, against, inter alia, Jampro, Tower Maintenance, and Channel 24, to recover the damages it sustained resulting from the collapse of the tall tower.
On August 13, 1973, OSHA filed two citations for alleged occupational safety and health violations against Jampro. OSHA then initiated proceedings before the Occupational Safety and Health Review Commission, OSHRC Docket No. 4456, but these were subsequently concluded by stipulation.
On March 2, 1977, plaintiff, by counsel, made a formal request under the terms of the Freedom of Information Act (FOIA) for seven categories of information obtained by OSHA in its investigation of the tall tower collapse. Although OSHA disclosed some portions of this information to plaintiff, thirteen witness statements were provided with substantial deletions. Plaintiff was later informed that certain portions of the witness statements were deleted in order to prevent "an unwarranted invasion of privacy and/or disclose the identity of a confidential source." On March 2, 1977, plaintiff made a formal request, pursuant to the terms of the FOIA for the entire text of such witness statements and the identity of the individuals who made them. This request was denied to the extent that such disclosure would reveal the identity of the interviewees. Plaintiff pursued its administrative remedies with the Department of Labor, apparently seeking only the identity of the person or persons who had made two particular statements to the OSHA investigator. In a subsequent letter, the plaintiff was informed that the requested information was exempt from disclosure, pursuant to exemption 7(D) of the FOIA.
In order to obtain the identities of the people who made the statements, plaintiff brought this action on September 9, 1977, to enjoin the defendants further from withholding the requested information.
The defendants argue that exemption 7(D) of the FOIA allows the defendants to withhold the identity of the interviewees
who made the two statements involved here to the OSHA investigators. The plaintiff opposes the application of this exemption in this case on the ground that an interviewee is not a "confidential source" within the meaning of the exemption.
Exemption 7(D) exempts from disclosure "investigatory records compiled for law enforcement purposes, but only to the extent that the production of such records would . . . disclose the identity of a confidential source . . ." 5 U.S.C. § 552(b)(7)(D). Both parties appear to agree that the two documents in issue are "investigatory records compiled for law enforcement purposes." The key issue, therefore, is whether an interviewee is a "confidential source."
The burden of proof is on the government agency asserting a privilege under the FOIA. 5 U.S.C. § 552(a)(4)(B). The Conference Report to the 1974 amendments to the FOIA, which altered exemption 7(D) to its present form, indicates that an agency may meet this burden of proof by proving either that the interviewee provided information "under an express assurance of confidentiality or in circumstances from which ...
