are you saying that NatGeo was/is irresponsible in reporting this...or that the EPA does NOT test for toxicity, or that ...
Let me restate it as clearly as I can -
(as opposed to conducts) toxicology tests and reports for all dispersants that are included on the (NCP) Product Schedule
, the list of candidate dispersants. All determinations regarding the specific application or use of a dispersant are made by the Federal On-Scene Coordinator in charge of the response, the USCG.
On May 26th, EPA and the Coast Guard issued a directive to BP requiring them to decrease
(as opposed to halt) overall volume of dispersant by 75 percent and to cease use of dispersant on the surface of the water altogether unless provided prior written authorization from the Coast Guard.
EPA/CG continues to allow BP to use undersea dispersant but only at a maximum of 15,000 gallons per day.
