(a) BLM will establish the appropriate effective date of an initial participating area or any revision to a participating area. The effective date may be, but is not limited to, the first day of the month in which:

1. (1) A well is completed that causes the participating area to be formed or revised;
2. (2) Commercial operations start; or
3. (3) New or additional technical information becomes known that provides a basis for revising the boundary (such as when production from, or injection to, an area outside the participating area first became known).
