Margaret D. McGaughey, Appellate Chief, with whom Paula D. Silsby, United States Attorney, was on brief for appellee.
Before BOUDIN, Circuit Judge, O'CONNOR,[*] Associate Justice (Ret.), and SELYA, Senior Circuit Judge.
SANDRA DAY O'CONNOR, Associate Justice (Retired).
Appellant claims the introduction into evidence of phone calls between him and Kenneth Durgin, an inmate in a correctional facility, violated the Federal Wiretap Act, 18 U.S.C. § 2510 et seq. Because Durgin consented to monitoring of his calls, we affirm the district court's denial of appellant's motion to suppress.

I.
Appellant Christopher Conley first came to the government's attention during an investigation into a drug trafficking ring. Kenneth Durgin, who was serving time in the Maine Correctional Center ("MCC"), was also suspected of involvement in that ring. Witnesses identified appellant as a potential member of the organization. But when he was called before a grand jury and interviewed by government agents, he denied his involvement with the group, his alias of "White Boy," and any relationship with Durgin.
Another arm of the investigation focused on inmate Durgin. Agent Paul McNeil *58 informed Peter Herring, the correctional investigator responsible for investigating alleged crimes at MCC, that he suspected Durgin was involved in ongoing drug trafficking operations while he was incarcerated. He requested permission to record and listen to Durgin's phone conversations. Permission was granted, and Herring transferred recordings of Durgin's calls to McNeil.
Unfortunately for appellant, the phone conversations were all too illuminating. During those calls, Durgin spoke with appellant. Appellant bragged that the government agents had asked him if he knew Durgin and if he went by the alias "White Boy." He told Durgin that he denied everything to the agents.
Appellant was charged with making a false statement to a government agency in violation of 18 U.S.C. § 1001(a)(2). After the district court denied his motion to suppress the phone calls, he pleaded guilty, conditional on this appeal of the suppression ruling.

II.
Appellant claims that the phone call should be suppressed for two reasons. First, he claims that the phone call was intercepted in violation of the Federal Wiretap Act, 18 U.S.C. § 2510 et seq., because Durgin had not consented to monitoring of his calls for the purpose of investigating criminal activity outside prison walls. Second, appellant claims that the phone call should have been suppressed because under 18 U.S.C. § 2517, Herring was not authorized to disclose Durgin's communications to McNeil.
Both arguments lack merit.

A. Durgin's Consent to Monitoring
Under the Federal Wiretap Act, wire or oral communications that have been intercepted in violation of the chapter are not admissible as evidence at trial. 18 U.S.C. § 2515. Section 2511(2)(c), however, authorizes telephone calls to be monitored if one party to the call consents to the monitoring. Thus, if Durgin granted consent to monitoring of his calls, their introduction into evidence would not violate the Federal Wiretap Act.
It is undeniable that Durgin consented to monitoring of his calls for at least some purposes. In United States v. Footman, 215 F.3d 145, 155 (1st Cir.2000), this Circuit recognized that "[p]rison inmates have few expectations of privacy in their communications." The inmate in that case signed a form indicating that he understood that any use of the telephone, except in calling an attorney, would be subject to monitoring. Stickers posted near telephones reminded inmates their calls were monitored. And at the commencement of every call, a recorded message indicated that the call was monitored. Under those circumstances, the First Circuit held that an inmate who placed a call to a non-attorney consented to monitoring of the call for purposes of the Federal Wiretap Act. Id. at 154-55.
Here, in order to place calls, Durgin received a PIN from the prison. The paperwork to obtain that PIN required him to consent to monitoring of his calls. As in Footman, placards placed near telephones warned that calls were subject to monitoring. Recorded messages heralded the monitoring of calls, and Durgin's own discussions on the telephone indicated that he was aware his calls were being recorded.
Durgin thus unambiguously consented to monitoring of his telephone conversations.
Appellant argues that we should nonetheless suppress the calls, because United States v. Correa, 220 F.Supp.2d 61, *59 64 (D.Mass.2002), held that the scope of a search is defined by the object of the search. That object, appellant says, is defined by MCC policy 21.3:
Prisoner telephone calls may be monitored by the department criminal investigator, or employee acting at the direction of the departmental criminal investigator, if the investigator is conducting the investigation of an offense related to security and orderly management of the facility. Only those prisoner telephone calls suspected to be related to the investigation may be monitored.
Appellant claims that Durgin's consent to monitoring was expressly bounded by MCC policy. Because his calls were not monitored for reasons related to either security or the orderly management of the prison, Durgin did not lawfully consent.
Appellant's argument fails for two reasons. First, even if Durgin's consent was limited to monitoring for the purposes of assuring prison safety and order, Herring, the prison administrator, allowed the monitoring because he believed Durgin was involved in an ongoing crime. Herring explained that the orderly management of the facility is threatened when inmates involve themselves in ongoing crimes.
We give great deference to a prison administrator's determination that prison safety is at risk. "Running a prison is an inordinately difficult undertaking that requires expertise, planning, and the commitment of resources, all of which are peculiarly within the province of the legislative and executive branches of government. Prison administration is, moreover, a task that has been committed to the responsibility of those branches, and separation of powers concerns counsel a policy of judicial restraint." Turner v. Safley, 482 U.S. 78, 84-85, 107 S.Ct. 2254, 96 L.Ed.2d 64 (1987). We thus give Herring's interpretation of the prison's own policy considerable weight, and conclude that monitoring of Durgin's calls was justified under MCC policy.
Appellant's argument suffers from a second fatal flaw: Durgin was unaware of the policy at issue. The question of the scope of monitoring of prison calls turns on "the notices that form the basis for a finding of consent." Correa, 220 F.Supp.2d at 64. The notices Durgin received did not reference MCC policy, and instead asserted that all calls, save those between attorney and client, would be monitored. When speaking with others on the phone, Durgin warned his colleagues not to discuss ongoing crimes because his calls were being recorded. He expressed no belief that the calls would be monitored only for certain purposes.
The evidence that Durgin consented to monitoring of his calls for the purpose of investigating ongoing crimes is thus overwhelming. His calls were thus properly intercepted under 18 U.S.C. § 2511(2)(c).

B. Legality of Disclosure under 18 U.S.C. § 2517
Appellant also argues that Herring, the correctional officer who provided access to the phone calls, lacked the authority to disclose those calls to Agent McNeil.
The authority to disclose communications between law enforcement officers stems from 18 U.S.C. § 2517. Section 2517 allows law enforcement officers to share communications "to the extent that such disclosure is appropriate to the proper performance of the official duties of the officer making or receiving the disclosure." But such disclosure is authorized only when the information was obtained "by any means authorized by this chapter." Id.
*60 Appellant does not question that Agent McNeil, the officer who received the disclosure, asked for the information as a proper performance of his official duties. Instead, appellant claims the information was not obtained by a means authorized by the chapter. Specifically, appellant points to section 2516, which authorizes law enforcement officers to seek court orders to intercept communications in certain specific instances. Because no court ordered Durgin's communications disclosed, appellant argues, Herring was not authorized to share the content of Durgin's calls.
Our reading of section 2517's authorization requirement is not so limited. Section 2517 allows one officer to disclose information to another if it was intercepted "by any means allowed in this chapter." Id. (emphasis added). That section is contained in Chapter 119, which also includes 18 U.S.C. § 2511(2)(c), which states that "[i]t shall not be unlawful under this chapter for a person acting under color of law to intercept a wire, oral, or electronic communication, where ... one of the parties to the communication has given consent to such interception." Chapter 119 thus clearly allows interception of material where one party consents.
As we have already established that Durgin consented to the interception of his phone calls, section 2517 allowed Herring to share the content of those calls with McNeil.

III.
Because Durgin consented to the monitoring of his calls, their introduction into evidence was proper.
AFFIRMED.
