Progressive Alaska has covered the use of dispersants there more than any other Alaska blog. Ott was already the world's leading opponent of dispersant use, and expert on their dangers before the ongoing spill (or spills), and her knowledge about them has grown immensely, as BP and the U.S. government have sought to hide both the amount of application being administered, how and where it is being done, and - most importantly - the widening toxic effects of the criminal use of these products.
The Mudflats has reprinted a long, annotated article/letter by Riki Ott, written on August 27th to Sam Coleman, head of the U.S. Evironmental Protection Agency, Region Six.
Here's a link to the article at The Mudflats. It is powerful, persuasive. It will be ignored. Here is how Dr. Ott's letter to Coleman begins:
Dear Mr. Coleman,
During the August 25 Dockside Chat in Jean Lafitte, LA, it came to our attention that the federal agencies were unaware — or lacking proof — of the continued spraying of dispersants from Louisiana to Florida. Further, the federal agencies were woefully ignorant of the presence of subsurface oil-dispersant plumes and sunken oil on ocean and estuary water bottoms. We offer evidence to support our statements, including a recently declassified subsurface assessment plan from the Incident Command Post.
But first, you mentioned that such activities (continued spraying of dispersants and sinking oil) — if proven — would be “illegal.” As you stated, sinking agents are not allowed in oil spill response under the National Contingency Plan Subpart J §300.910 (e): “Sinking agents shall not be authorized for application to oil discharges.”
Please be careful, Riki!
