On February 25, 2009, OCP Ecuador S.A. faced its first major incident; an oil spill consisting of 11,700 barrels of heavy crude oil in an area of high biodiversity in eastern Ecuador. An earth movement caused stress in the pipeline that resulted in its breakage. The temporarily impacted area covered 30 hectares of soil and gravel along 180 kilometers of three rivers that form the high watershed of the Amazon River; these rivers are the Santa Rosa, Quijos and the Coca.

A paper describing the model implemented to manage the emergency, clean up and remediation activities was presented during the 2010 International Pipeline Conference. Now, 3 years later, this paper presents the final conclusions and lessons learned once the remediation, approval process and subsequent monitoring have been completed.
