[1] The spill was also notable for the volume of Corexit oil dispersant used to help disperse the oil. Although approved by the EPA, no toxicology studies had been done at this time.

Pemex contracted Conair Aviation to spray the chemical dispersant Corexit 9527 on the oil. A total of 493 aerial missions were flown, treating 1,100 square miles (2,800 km 2) of oil slick.

The slick was described in the official report as "a moderate sheen with streaks of heavy dark oil moving round the stern of the vessel." Tug boats were driven through the slick in an attempt to break it up, and the spraying of chemical dispersant commenced soon after the spill occurred. 400 litres of Corexit 7764 and 4200 litres of Corexit 9527 were supplied by Santos.
