I do not understand how an area can have a policy of banning intinction. From the 2004 Instruction Redemptionis Sacramentum:
“[103.] The norms of the Roman Missal admit the principle that in cases where Communion is administered under both kinds, “the Blood of the Lord may be received either by drinking from the chalice directly, or by intinction, or by means of a tube or a spoon”. As regards the administering of Communion to lay members of Christ’s faithful, the Bishops may exclude Communion with the tube or the spoon where this is not the local custom, though the option of administering Communion by intinction always remains. …”
This document has at the end:
"All things to the contrary notwithstanding.
This Instruction, prepared by the Congregation for Divine Worship and the Discipline of the Sacraments by mandate of the Supreme Pontiff John Paul II in collaboration with the Congregation for the Doctrine of the Faith, was approved by the same Pontiff on the Solemnity of St. Joseph, 19 March 2004, and he ordered it to be published and to be observed immediately by all concerned.
From the offices of the Congregation for Divine Worship and the Discipline of the Sacraments, Rome, on the Solemnity of the Annunciation of the Lord, 25 March 2004.

A policy that bans the option of intinction is not consistent with this Instruction. Obviously I am talking about intinction as described in the Roman Missal.
