From the various studies already conducted and published, we do not recognise that conclusion. I would refer you to the response website (http://www.restorethegulf.gov/) and the NOAA [US National Oceanic & Atmospheric Administration] website...as the main sources of information on the environmental impacts of the Macondo spill. Notwithstanding the above, we have however provided $500m for continuing long-term scientific studies into the spill and its impact.
