922.121—Definitions.
In addition to those definitions found at § 922.3, the following definition applies to this subpart:
No-activity zone means the two geographic areas delineated by the Department of the Interior in stipulations for OCS lease sale 112 over and surrounding the East and West Flower Garden Banks, and the geographic area delineated by the Department of the Interior in stipulations for OCS lease sale 171 over and surrounding Stetson Bank, as areas in which activities associated with exploration for, development of, or production of hydrocarbons are prohibited. The precise aliquot part description of these areas around the East and West Flower Garden Banks are provided in appendix B of this subpart; the no-activity zone around Stetson Bank is defined as the 52 meter isobath. These particular aliquot part descriptions for the East and West Flower Garden Banks, and the 52 meter isobath around Stetson Bank, define the geographic scope of the “no-activity zones” for purposes of the regulations in this subpart. The descriptions for the East and West Flower Garden Banks no-activity zones are based on the “ 1/4 1/4 1/4 ” system formerly used by the Department of the Interior, a method that delineates a specific portion of a block rather than the actual underlying isobath.
