The other side of the process is issuing leases. Lifting the ban would not by itself do anything. Somebody, Congress probably, would have to decide how much the leases will cost. Size, duration, and other factors involved in bureaucratic admin would be done in the Exec branch.
Agreed there are many steps, but it requires first getting started. Congress themselves would not make those detail decisions. Mineral Managament Service which is under the Excutive branch would administrate it.
But Congress has to approve releasing the area and appropriate funds for them to do the work.
Each step will bring us closer, but until Congress lifts the ban, we haven’t gotten started.
