Whenever the target of the electronic surveillance is a foreign power, as defined in section 1801 (a)(1), (2), or (3) of this title, and each of the facilities or places at which the surveillance is directed is owned, leased, or exclusively used by that foreign power, the order need not contain the information required by subparagraphs (C), (D), and (F) of subsection (c)(1) of this section, but shall generally describe the information sought, the communications or activities to be subjected to the surveillance, and the type of electronic surveillance involved, including whether physical entry is required.
(e) Duration of order; extensions; review of circumstances under which information was acquired, retained or disseminated

(3) At or before the end of the period of time for which electronic surveillance is approved by an order or an extension, the judge may assess compliance with the minimization procedures by reviewing the circumstances under which information concerning United States persons was acquired, retained, or disseminated.
(f) Emergency orders 
Notwithstanding any other provision of this subchapter, when the Attorney General reasonably determines that
(1) an emergency situation exists with respect to the employment of electronic surveillance to obtain foreign intelligence information before an order authorizing such surveillance can with due diligence be obtained; and
(2) the factual basis for issuance of an order under this subchapter to approve such surveillance exists;

he may authorize the emergency employment of electronic surveillance if a judge having jurisdiction under section 1803 of this title is informed by the Attorney General or his designee at the time of such authorization that the decision has been made to employ emergency electronic surveillance and if an application in accordance with this subchapter is made to that judge as soon as practicable, but not more than 72 hours after the Attorney General authorizes such surveillance. If the Attorney General authorizes such emergency employment of electronic surveillance, he shall require that the minimization procedures required by this subchapter for the issuance of a judicial order be followed. In the absence of a judicial order approving such electronic surveillance, the surveillance shall terminate when the information sought is obtained, when the application for the order is denied, or after the expiration of 72 hours from the time of authorization by the Attorney General, whichever is earliest. In the event that such application for approval is denied, or in any other case where the electronic surveillance is terminated and no order is issued approving the surveillance, no information obtained or evidence derived from such surveillance shall be received in evidence or otherwise disclosed in any trial, hearing, or other proceeding in or before any court, grand jury, department, office, agency, regulatory body, legislative committee, or other authority of the United States, a State, or political subdivision thereof, and no information concerning any United States person acquired from such surveillance shall subsequently be used or disclosed in any other manner by Federal officers or employees without the consent of such person, except with the approval of the Attorney General if the information indicates a threat of death or serious bodily harm to any person. A denial of the application made under this subsection may be reviewed as provided in section 1803 of this title.

Notwithstanding any other provision of this subchapter, officers, employees, or agents of the United States are authorized in the normal course of their official duties to conduct electronic surveillance not targeted against the communications of any particular person or persons, under procedures approved by the Attorney General, solely to
(1) test the capability of electronic equipment, if
(A) it is not reasonable to obtain the consent of the persons incidentally subjected to the surveillance;
(B) the test is limited in extent and duration to that necessary to determine the capability of the equipment;
(C) the contents of any communication acquired are retained and used only for the purpose of determining the capability of the equipment, are disclosed only to test personnel, and are destroyed before or immediately upon completion of the test; and:
(D) Provided, That the test may exceed ninety days only with the prior approval of the Attorney General;

(1) In this subsection
(A) the term production order means an order to produce any tangible thing under this section; and

(A) 
(i) A person receiving a production order may challenge the legality of that order by filing a petition with the pool established by section 1803 (e)(1) of this title. Not less than 1 year after the date of the issuance of the production order, the recipient of a production order may challenge the nondisclosure order imposed in connection with such production order by filing a petition to modify or set aside such nondisclosure order, consistent with the requirements of subparagraph (C), with the pool established by section 1803 (e)(1) of this title.
(ii) The presiding judge shall immediately assign a petition under clause (i) to 1 of the judges serving in the pool established by section 1803 (e)(1) of this title.

(2) Defined 
In this section, the term minimization procedures means
(A) specific procedures that are reasonably designed in light of the purpose and technique of an order for the production of tangible things, to minimize the retention, and prohibit the dissemination, of nonpublicly available information concerning unconsenting United States persons consistent with the need of the United States to obtain, produce, and disseminate foreign intelligence information;
(B) procedures that require that nonpublicly available information, which is not foreign intelligence information, as defined in section 1801 (e)(1) of this title, shall not be disseminated in a manner that identifies any United States person, without such persons consent, unless such persons identity is necessary to understand foreign intelligence information or assess its importance; and
(C) notwithstanding subparagraphs (A) and (B), procedures that allow for the retention and dissemination of information that is evidence of a crime which has been, is being, or is about to be committed and that is to be retained or disseminated for law enforcement purposes.

Information acquired from tangible things received by the Federal Bureau of Investigation in response to an order under this subchapter concerning any United States person may be used and disclosed by Federal officers and employees without the consent of the United States person only in accordance with the minimization procedures adopted pursuant to subsection (g).
