Exxon Mobil was notified by the federal regulators, saying that they are retooling Exxon’s primary proposal in cleaning up the Yellowstone River’s oil spill, which was caused by a damaged pipeline. The plan should be kicked off in the beginning of July.

Steve Merritt, an official from the US Environmental Protection Agency expressed that there are only 3 factors of the proposal that were not complete. Additionally, Merritt explained that the company must make a revision on its plans of capturing the oil spilled on the river, restoring the habitat and private property affected by the spill and removing the damaged pipe without causing pollution downstream.

Moreover, Merritt emphasized that the officials requested Exxon to complete the revised plans within one week.

Exxon’s spokesperson Pius Rolheiser explained that they are working closely with officials of EPA on the outline of their proposal and will fulfill EPA’s request.

Furthermore, the proposal’s details will not be revealed not until Montana and EPA officials accept it. Merritt clarified that the local government had already approved the preliminary proposal only for several factors such as the disposal of dangerous waste.

EPA also ordered Exxon to finish the clean up on September 9. The river is recognized for it’s near pristine waters, rich wildlife and scenic beauty.

The company has already made an apology for the oil spill on Yellowstone and promised to bring back its richness.
