Inaccuracy vs Fact About COREXIT Products
/*(NEW) INACCURACY: Tests on Gulf workers show significant exposure to
2-butoxyethanol.*/
FACT: OSHA conducted testing for exposure to 2-butoxyethanol on relief
workers in the Gulf of Mexico. According to Greenwire.com "OSHA's
analysis of raw BP testing data concluded that among the 20 percent of
sampled workers exposed to 2-butoxyethanol, 'the highest level measured
was 0.8 ppm, and 90% of those were 0.2 ppm or less,' according to a
statement from the agency. 'Every measurement was well below the NIOSH
recommended limit of 5.0 ppm.'" The full Greenwire story can be read
here.
2-butoxyethanol is a componenet of COREXIT 9527, which was used
sparingly in the early days of the Gulf oil spill. COREXIT 9500, which
does not contain 2-butoxyethanol, has been exclusively used for the
majority of the remediation effort.
/*INACCURACY: The chemical formula of COREXIT has not been disclosed.*/

FACT: Nalco has provided the Federal Government with all information
relating to the chemicals and compounds in our product and is willing to
provide this data to any state government that wants the information to
analyze the effects of dispersants and protects the confidentiality of
the proprietary information. We have complied with every request for
information and assistance we have received from the Federal Government
that is needed to protect human health and the environment and will
continue to do so as we help mitigate the damaging consequences of the
oil spilling into the Gulf. The ingredients to COREXIT products are
available here .
/*INACCURACY: COREXIT is banned in the United Kingdom.*/
FACT: Corexit is approved in over 30 countries and we are unaware of a
single country that has banned Corexit. The UK does not allow the use
of Corexit for rocky shoreline application because it results in snails
and other crustaceans not sticking to rocks. Corexit was not designed
for rocky coast application and is only applied in the United States at
least 3 miles off shore. However, Corexit 9500 did pass the UK test for
off-shore use (what it was designed for) and existing stock use is
allowed for that intended application with notification to appropriate
authorities.
/*INACCURACY: The EPAs May 20 dispersant directive ordered BP to stop
7/29/2019 Corexit
7/11
using COREXIT.*/
FACT: The EPAs dispersant directive
gave BP
24 hours to identify a less toxic and equally effective alternative if
one existed, but as EPA Administrator Jackson said in a May 24 press
conference
, there
was no order they had to switch. The directive indicated that If BP was
unable to identify a less toxic and equally effective dispersant from
the EPAs approved list within 24 hours, BP would provide an explanation
to the EPA as to why the current dispersant (COREXIT) was the least
toxic and most effective option available. BPs response to the EPAs
directive is available here
.
In addition, during a press call hosted by Paul Anastas, assistant
administrator for the Office of Research and Development at EPA, on June
30 regarding the EPA's first round of independent dispersant testing,
Anastas further clarified EPAs directive, stating, let me be clear
about what we expected of BP. We expected them to, one, seek out the
least toxic dispersant and to always be asking that question and always
looking to identify that. And two, minimize the use of dispersant
wherever possible to effectively deal with this crisis. And one of the
things and I'll refer back to my statement that we've seen that after
7/29/2019 Corexit
8/11
the Administrator made that communication to BP, we have seen the use of
dispersants decrease by almost 70 percent from its peak usage.
He went on to say, I think the important thing to clarify is what the
administrator directed BP to do is to look at other dispersants in order
to always ask the question about, "Are we using the safest, most
effective dispersant that we can?" Its important that BP do that. Its
important that we always bring to bear the most effective and safe
dispersants for human health and the environment. And I think that
that's the request that the Administrator made and that's what we will
continue to insist upon. The full transcript of the June 30 press call
can be found here

/*INACCURACY: COREXIT dispersant is the primary hazard to marine life in
the Gulf.*/
FACT: The EPA has indicated that COREXIT has been safe and effective in
mitigating the impact of the oil on the environment. According to the
EPA , toxicity data
does not indicate any significant effects on aquatic life. Moreover,
decreased size of the oil droplets is a good indication that, so far,
the dispersant is effective. EPA Administrator Jackson also said that
COREXIT has been effective in speeding biodegradation, and USCG Rear
Admiral Landry indicated that COREXIT has prevented much more highly
7/29/2019 Corexit
9/11
toxic oil from reaching US shorelines. (source: May 24 EPA Press
Conference on Dispersant Use in the Gulf of Mexico
).
According to Luann White, Director, Tulane Center for Applied
Environmental Public Health Its not the dispersants that cause the
ecological effects its the oil thats toxic. None of these
dispersants is so innately toxic -- once you use them out in the Gulf,
theyre not going to cause toxic effects in and of themselves. Tulane
University, June 2, 2010 .
/*INACCURACY: COREXIT dispersant is highly toxic.*/
FACT: All of the ingredients contained in Nalcos dispersants are safe
and found in common household products, such as food, hand and body
lotion, packaging, cosmetics, and household cleaners. Corexit is
approved for use by the EPA because it falls well within the agencys
range of allowable toxicity levels. Corexit products biodegrade rapidly,
do not bioaccumulate, are not human carcinogens, do not degrade into
endocrine disruptors, and are not reproductive toxins. Common household
soaps are more toxic to marine life than Corexit.
In fact, Paul Anastas, the EPAs assistant administrator for research
and development, told reporters Wednesday (June 30) that the Corexit
9500 being used by oil company BP is among the least toxic to small
7/29/2019 Corexit

fish of the eight products tested (Dispersants appear to break up in
Gulf, EPA says, CNN Wire Staff, June 30, 2010).
/*INACCURACY: COREXIT dispersant is hazardous to human health when used
as directed.*/
FACT: All of the ingredients contained in Nalcos dispersants are found
in common household products, such as food, packaging, cosmetics, and
household cleaners. Individually and collectively the ingredients are
safe when used as directed. A May 13 Centers for Disease Control Oil
Spill Dispersant Information for Health Professionals
document notes that, Because of the strict guidelines that must be
followed to utilize dispersants it is unlikely that the general public
will be exposed to straight product. The report further states that
ingredients are not considered to cause chemical sensitization; the
dispersants contain proven, biodegradable and low toxicity surfactants.
/*INACCURACY: COREXIT dispersant will evaporate into clouds and come
back down in the rain*/
FACT: COREXIT dispersants are made to disperse oil into the water column
and not to evaporate. They biodegrade into the water and are not
released back into the atmosphere. In fact, Admiral Thad Allen noted at
7/29/2019 Corexit
11/11
a June 11 press conference that the primary surface use of Corexit is to
protect worker safety.
http://www.deepwaterhorizonresponse.com/go/doctype/2931/54095/.
/*INACCURACY: COREXIT dispersants will drift to populated areas when
sprayed from airplanes.*/
FACT: COREXIT is meant to be used at sea away from the shoreline and
has been used in more than 30 countries, including Sweden, France,
Australia, Norway and Canada. Aerial spraying of dispersant is not to
take place within 2 miles of a boat or 3 miles of a shoreline. With
30-mile per hour winds, the maximum expected drift for the dispersant is
2,000 feet. Spraying of dispersant from boats should only be done with
personal protective equipment. Again, the Centers for Disease Control
says it is highly unlikely that the general public will be exposed to
Corexit dispersants. Mists of the dispersant will not stray far from the
boat given the proximity of the spray to the surface of the water.
