In July 2015, following implementation of PEP, ICE began using revised forms, the I-247D detainer form and the I-247N, a request for notification form. In addition to the I-247D and I-247N, in late 2015 ICE began using the I-247X immigration detainer form, which applies to non-PEP priority subcategories, and which ICE may use to seek custody transfers from cooperative jurisdictions. Each of the 24 ICE Field Office Directors whose areas of responsibility includes at least one location that does not honor detainers are in ongoing discussions with their law enforcement partners in order to tailor PEP in each location to best meet the needs of their communities.
The island of Itsukushima is considered a sacred location in Shinto belief, and is the site of the Itsukushima Shrine , an UNESCO World Heritage Site . Purity is of utmost concern in Shinto worship, and because of this, the shrine's priests have attempted to keep the island free of the pollution of death. Immediately after the Battle of Miyajima in 1555, the only battle to have taken place on the island, the victorious commander had the bodies of the fallen troops removed to the mainland, and ordered that the entire battlefield be cleansed of the blood that was spilled, to the point that buildings were scrubbed and blood-soaked soil was removed from the island.  Retaining the purity of the Itsukushima Shrine is so important that since 1878, no deaths or births have been permitted near the shrine.  To this day, pregnant women are supposed to retreat to the mainland as the day of delivery approaches, as are terminally ill or the very elderly whose passing has become imminent. Burials on the island are still forbidden.
