In the GOM Energy Security Act of 2006, LA, TX, MS, and AL were given a share of federal royalties from the OCS expressly for the purpose of coastal protection and restoration, and hurricane protection.
The first lease sale occurred in 2007 so those wells have been drilled and have been producing. Louisiana has their first payment coming for this very soon, tho they have asked for earlier disbursement.
Plus, those 4 states, since the spill, have been agitating and saying that they should get an even bigger cut of the federal royalties, because of the spill.
Likewise, FL is now saying that they also have risks and they should get their share of the federal royalties.
I’ve read that one reason for the delay was to ensure that the building wouldn’t funnel the oil into Mississippi. I could see that being a valid reason to delay, as this isn’t exactly the same thing as the coastal restoration issue.
