(d) Facilities shall implement written procedures for the regular review of all vulnerable detainees placed in administrative segregation for their protection, as follows:

1. (1) A supervisory staff member shall conduct a review within 72 hours of the detainee's placement in administrative segregation to determine whether segregation is still warranted; and
2. (2) A supervisory staff member shall conduct, at a minimum, an identical review after the detainee has spent seven days in administrative segregation, and every week thereafter for the first 30 days, and every 10 days thereafter.

(f) Upon receiving notification pursuant to paragraph (e) of this section, the ICE Field Office Director shall review the placement and consider:

1. (1) Whether continued placement in administrative segregation is warranted;
2. (2) Whether any alternatives are available and appropriate, such as placing the detainee in a less restrictive housing option at another facility or other appropriate custodial options; and
3. (3) Whether the placement is only as a last resort and when no other viable housing options exist.
