This is an appeal from an order of the district court enforcing an administrative subpoena served on appellant Stephen B. Comley by the Nuclear Regulatory Commission (“NRC” or “Commission”). The subpoena seeks tape recordings or transcripts prepared by Comley of telephone conversations between Comley and an NRC employee who is the subject of an NRC investigation. Comley challenges the Commission’s authority to issue the subpoena and also contends that the subpoena violates his first amendment right to freedom of association. For the reasons discussed below, we affirm the district court’s order enforcing the subpoena.
*541 I. BACKGROUND
In August, 1988, the NRC’s Office of Inspector and Auditor (“OIA”) received allegations that an employee in the NRC’s Office of Investigations (“01”) had committed various acts of misconduct. The allegations were made by Douglas Ellison, a former employee at the Nine Mile Point nuclear power facility in Lycoming, New York. Ellison claimed, among other things, that the NRC employee had disclosed confidential NRC information to appellant Comley, a private citizen.
Ellison provided the OIA with a tape recording of two conversations that allegedly took place between the NRC employee and Comley. Administrative Judge Alan Rosenthal, who was placed in charge of the NRC’s investigation, reviewed the tape and concluded from it that the NRC employee may have disclosed confidential NRC information to Comley and may also have failed to disclose to other NRC officials relevant information that he had received from Comley. Based on Ellison’s statement that Comley may have recorded as many as fifty conversations between himself and the employee, the Commission issued a subpoena duces tecum to Comley for tapes of conversations between himself and the employee, or transcripts of such conversations. Comley moved the Commission to quash the subpoena, but this motion was denied. After Comley gave notice of his refusal to comply with the subpoena, the United States petitioned for enforcement in federal district court. Following a hearing, the district court entered an order enforcing the NRC’s subpoena. The court concluded that the subpoena was regular on its face, issued for valid purposes, and not violative of Comley’s first amendment right to freedom of association. Comley now appeals that decision. 1
II. STANDARDS GOVERNING THE ENFORCEMENT OF SUBPOENAS
In general, an agency subpoena is enforceable if it is for a proper purpose authorized by Congress, the information sought is relevant to that purpose and adequately described, and statutory procedures are followed in the subpoena’s issuance.
See, e.g., United States v. Powell,
Measured against these general standards, the NRC has made an adequate *542 prima facie showing to support enforcement of its subpoena. First, the Commission has articulated a proper purpose for issuing the subpoena. Congress has vested the NRC with the authority to issue subpoenas in conjunction with investigations that the NRC deems necessary to protect public health or to minimize danger to life or property in matters involving nuclear materials. 42 U.S.C. § 2201(c) (1982). It is precisely this objective of protecting public health and safety that the Commission has given as one of the purposes underlying its subpoena of the tape recordings at issue. The affidavit of Administrative Judge Rosenthal states that the information he has reviewed thus far leads him to suspect that the NRC employee under investigation may have received relevant information from Comley that NRC regulations required him to report to his superiors. Specifically, an NRC regulation requires 01 employees to keep NRC officers currently apprised of information received that pertains to public health and safety in matters involving nuclear materials. 10 C.F.R. § 1.27(f) (1989). If the NRC employee under investigation received such information from Comley and failed to relay it to his superiors, such misconduct clearly implicates the effective functioning of the NRC in its duty to protect public health and safety. A subpoena issued as part of an investigation into such alleged misconduct thus is supported by a proper agency purpose.
The Rosenthal affidavit also states that the information reviewed thus far indicates that the NRC employee may have divulged confidential NRC information to Comley. Depending on the information involved, this conduct might compromise the security of certain nuclear power facilities in the country. For this reason as well, the Commission’s investigation implicates public health and safety concerns in nuclear matters and provides a proper purpose for the issuance of the challenged subpoena.
Having made a prima facie showing of proper purpose, the Commission then must show that the information sought by the subpoena is reasonably relevant to the purpose of the investigation, and that the subpoena itself is not too indefinite. There can be little doubt that the tape recordings sought by the subpoena are relevant to the purpose of the Commission’s investigation. The Commission’s objective is to uncover any misconduct relating to the NRC employee’s conversations with Comley. The tape recordings of these conversations certainly are relevant to this investigation. Second, the subpoena itself is not too indefinite. It specifically requests tape recordings or transcripts of tape recordings of conversations between Comley and the NRC employee. There is little that is indefinite in this request. We thus find that the NRC has made an adequate prima facie showing to support enforcement of its subpoena.
III. CHALLENGES TO ENFORCEMENT OF THE SUBPOENA
Comley challenges the subpoena’s enforcement on two grounds. First, he contends that the Commission lacked authority to issue the subpoena. Second, even if the Commission had authority, Comley argues that the subpoena’s enforcement would violate his first amendment right to freedom of association. We consider each of these arguments in turn.
A. Commission's Authority to Issue Subpoena
Comley’s challenge to the Commission’s authority to issue the subpoena essentially is a challenge to the Commission’s professed “public health and safety” motivations for investigating the NRC employee in question. Comley contends that the Commission is motivated only by bad faith in its investigation of the employee. He alleges that there is some sort of vendetta within the NRC to get rid of this employee, and that it is this vendetta rather than any concern for public health and safety that is motivating the investigation.
If Comley’s assertions were supported by firm evidence, then we would have adequate justification to deny enforcement of the subpoena. “[I]f a subpoena is issued
*543
for an improper purpose, such as harrassment [sic], its enforcement constitutes an abuse of the court's process.”
United States v. Westinghouse Elec. Corp.,
Comley has asked for discovery and an evidentiary hearing to explore more thoroughly the issue of the Commission’s bad faith. The district court denied this request and we affirm the denial. “ ‘Except in extraordinary circumstances ..., discovery is improper in a summary subpoena enforcement proceeding.’ ”
FTC v. Carter,
B. Freedom of Association
Comley’s final challenge to the NRC’s subpoena is that enforcement of the subpoena would infringe on his first amendment right to freedom of association. Comley is the founder and director of a non-profit corporation that monitors and investigates the operation and construction of nuclear power plants and frequently criticizes the activities of the NRC. Comley claims that relinquishing the tape recordings sought in the subpoena would result in the “detailed disclosure of organizational activities, the identities of individuals that either belong to or associate with the organization and Mr. Comley, and likely expose those persons and others who have provided information to Mr. Comley to retaliation by their employers, the Commission and others." Brief for Appellant at 32.
In a line of cases beginning with
NAACP v. Alabama,
Applying this framework, we conclude that Comley has failed to make out an adequate claim that enforcement of the subpoena would violate his right to freedom of association. First, we have reservations about the strength of the first amendment concerns implicated by the challenged subpoena. Unlike the disclosure requirements involved in the majority of the cases we have reviewed, the subpoena issued by the NRC does not directly require the disclosure of the identities of Comley’s associates or informants.
See, e.g., Brown v. Socialist Workers ’7b Campaign Comm.,
Furthermore, for the most part, Comley has made only general allegations concerning the harassment or harm that will result to his associates if their identities indeed are revealed by the tape recordings. These general allegations of harassment fall short of the solid, uncontroverted evidence of actual harassment that has existed in those cases where the Supreme Court has found violations of the right to freedom of association.
See Brown v. Socialist Workers ’7b Campaign Comm.,
Even assuming, however, that Corn-ley has made an adequate prima facie showing of protectable first amendment interests, we must reject Comley’s first amendment challenge to the subpoena. We reject the challenge because of our conclusion that the government has adequately shown both a compelling interest in obtaining the material sought and that no significantly less restrictive alternatives exist. The requirement of a compelling interest is met by the NRC’s mission to promote nuclear safety.
See United States v. Garde,
IV. CONCLUSION
The Commission has made an adequate prima facie showing that its subpoena was issued for an authorized purpose, and that the information sought is relevant to that purpose and adequately described. We find Comley’s allegations of bad faith to be insufficient to overcome this showing or to require discovery and an evidentiary hearing. Finally, with respect to the freedom of association challenge, we have reservations about the strength of the first amendment concerns implicated by the subpoena. Even assuming a prima facie showing of sufficient first amendment concerns, however, we conclude that the government has a compelling interest in the material sought and that there are no significantly less restrictive alternatives available. The district court’s order enforcing the Commission’s subpoena is therefore Affirmed.
Notes
. At oral argument, we raised several questions concerning our jurisdiction to consider Corn-ley's appeal from the enforcement order. The questions focused on whether it was proper for Comley to appeal from the enforcement order or whether he could appeal only from a contempt adjudication. Further examination has persuaded us that jurisdiction does exist to consider an appeal from the enforcement order. "[Ojrders compelling testimony or production of evidence in what may properly be regarded as independent proceedings are appealable without the requirement of a contempt adjudication. This rule is regularly applied in proceedings where evidence is sought by administrative agencies.”
Mount Sinai School of Medicine v. American Tobacco Co.,
. In addition to the justification of protecting health and safety, the NRC also claims that it has the authority to issue subpoenas in the course of investigating employee misconduct, even if such misconduct does not directly implicate public health and safety. Comley challenges this assertion, arguing that the Civil Service Reform Act of 1978 preemptively establishes the procedures that agencies may employ in disciplinary proceedings, and that this Act does not provide for the issuance of subpoenas in investigations of employee misconduct. We need not consider this issue because of our conclusion that the employee misconduct alleged here does implicate public health and safety concerns. The possibility that the NRC employee failed to relay to his superiors relevant information received from Comley or that he passed on to Comley confidential information pertaining to plant security obviously implicates public health and safety, and thus furnishes proper justification for the agency’s use of its subpoena power.
