U.S. Environmental Services' workers move oil containment boom onto a supply boat in Venice, La., April 29, 2010. Staging areas are being set up along the Gulf Coast to actively identify, target and protect environmentally and economically sensitive areas.

I was able to participate in this afternoon’s media briefing by Assistant to the President for Homeland Security John Brennan and U.S. Coast Guard Commandant Admiral Thad Allen. Adm Allen has been named the National Incident Commander for the response to the BP / Deepwater Horizon oil spill in the Gulf of Mexico.
With the declaration that the oil leak at the Deepwater Horizon accident site is a “Spill of National Significance” (SONS), a number of Federal processes began. Coast Guard Commandant Admiral Thad Allen’s appointment as Incident Commander was not an accident. Allen told us in his introduction that he held that same post for a SONS exercise in New Orleans in 2002 that dealt with a simulated wellhead blowout. He also said that the last SONS exercise was held a month ago, in Maine.
Allen described the current situation for the media. At this time there are three leaks in the remaining piping. There is a crimp in the piping just above the casing for the well that may be restricting the outflow from the well. It is impossible to make an accurate estimate of the leak’s volume. It is much more important to assess how much oil is reaching the surface over the next weeks.
At the time of the brief, Adm. Allen told us that no heavy oil had reached the beaches. The weather is pushing the slick towards the Louisiana coast but that may change. He said “Mother Nature has a vote”.
Current weather conditions at sea are restricting the use of aircraft to spread dispersal agents. Wind and wave conditions are not suitable. Two Air Force C-130 aircraft have been working along with commercial aircraft. The Air Force can seed dispersal agent over 250 acres at a pass. Allen indicated that a request for two additional aircraft has been made to the Air Force.
An experimental attempt to introduce dispersal agent at the leak site appears to have had some success, according to Allen. Cofferdams around the leaks with the oil being pumped to the surface are another option being considered.
I asked about altering the outflow of the Mississippi to increase the water flowing in to the Gulf. Admiral Allen told us that this was under consideration for Mobile Bay if the slick should reach that area. It is an option for the Mississippi.
The Admiral told us that shipping routes to and from the various ports in the region, known as fairways, have not yet been affected. Planning is underway if the slick should begin to affect those routes.
