William J. Dircks Executive Director for Operations From:
Guy H. Cunningham, III Executive Legal Director
SUBJECT:
STATUS OF MATTER INVOLVING ALLEGATIONS OF ANONYMOUS INFORMANT IN CONNECTION WITH THE DIABLO CANYON APPLICATION During your staff meeting last Thursday, you requested that I advise you of the status of discussions with the Department of Juctice regarding the submission of information to the staff by the Joint Intervenors' in the Diablo Canyon case.
By letter dated March 28, 1983, David S. Fleischaker, one of the counsel for the Joint Intervenors in the Diablo Canyon licensing proceeding transmitted to Darrell G. Eisenhut, Director, DL, a sumary of eight allegations received from an anonymous individual. The letter and attached summary of allegations were issued as Board Notification 83-48, on April 4,1983.
Subsequently, discussions were held with Mr. Fleischaker and Joel Reynolds, another counsel for the Joint Intervenors in an effort to obtain clarification of further information regarding the allegations. These efforts to obtain the infomation or to meet with the unidentified source were unsuccessful and, on April 21,1983, a fomal request was sent to Mr. Fleischaker. By letter dated April 28, 1983, Mr. Fleischaker responded, advising that the informant was unwilling "to meet with the NRC Sthff, fearful of PG&E/Bechtel reprisals." Except as noted below, no further communications with either Mr. Fleischaker or Mr. Reynolds occurred.
On August 3,1983, the Staff, in reviewing a filing by the Joint Intervenors regarding a discovery dispute in the ongoing reopened licensing proceeding, became aware that information regarding the allegations was also transmitted to the House Committee on Interior and Insular Affairs and Subcommittee on Energy and the Environment as well as the Department of Justice (00J).
In their filing, Joint Intervenors advise that they "have been explicitly requested by the Department of Justice [through its Deputy Chief for Litigation, Criminal Division] -- as the government agency receiving the information -- to assert the informer's privilege to prevent discicsure...."
In an effort to determine whether, DOJ has possession of and would provide access to any safety-related information bearing on the allegations, in additiar. to the sumary of the eight allegations provided to the Commission by Mr. Fleischaker's March 28th letter, OELD with OIA contacted the Deputy I,
se a
0' g3o93
..~
h Chief for Litigation, Criminal Division at DOJ on August 4th and 5th.
We were informed that, in light of representations made to by Mr. Reynolds, it was their understanding that disclosure of the information would likely reveal the identity of the informant and that the informant was concerned about disclosure even to the NRC.
Consequently, even though the information might be safety-related, 00J was initially unwilling to provide the information to us (or for that matter, even to describe what information they may have).
D0J's only suggestion was that we pursue the matter further with Mr. Reynolds and that they would likely abide by any agreement or accommodation reached with Mr. Reynolds.
In light of the futility of prior discussion with Mr. Reynolds on this subject, this avenue was not then followed.
Subsequently, by letter dated August 9th, 00J advised Mr. Reynolds, seemingly based on our discussions, that it no longer had an objection to the disclosure of the technical information sought by the staff (as well as by PG&E) that would not reveal the informant's identity.
On the basis of this
, letter, a further discussion was had with D0J, confirmed by our letter of August 15th, during which D0J agreed to provide to us all safety-related information not already provided in the initial documents sent to us by the Joint Intervenors. We have not received a reply from DOJ to date. A further discussion, again unsuccessful, was had with Mr. Reynolds to determine whether in light of D0J's August 9th letter, information could be provided to the Staff - directly by the Joint Intervenor.
In the meantime, the Appeal Board considering the reopened Diablo Canyon proceeding, has also had to address 'in the context of discovery, the question of the disclosure of the information from the anonymous informant. The Board, at the August 23-24 Prehearing Conference," directed that the Joint Intervenors provide to it only, whatever information they have that would be responsive to the discovery request so that it can determine in camera the relevance of this information to the proceeding and the meritTof any claimed privileged.
In addition, the staff was encouraged by the Board to continue in its efforts to obtain relevant information from D0J.
