ExxonMobil tries to avoid paying for new remediation efforts

SUMMIT COUNTY — Federal scientists say oil from the Exxon Valdez spill more than 20 years ago is still affecting coastal ecosystems in Alaska and requires more restoration efforts — But Exxon (now ExxonMobil) attorneys are asking a federal court to release the company from any additional financial liability for the spill.

According to recent documents filed with U.S. District Court in Alaska, some of the oil that gushed from the busted tanker is degrading more slowly than anticipated and remains as a toxic exposure threat to to sea otters, harlequin ducks and other animals using intertidal habitats.

According to the latest court filings, discovery of the oil raises several questions that must be addressed before finalizing the details of a restoration plan, including the location and extent of the oil, factors limiting natural degradation and a quest for new technologies to accelerate the degradation and dispersal of the residue.

Continues.

The Exxon Valdez oil spill took place 22 years ago.
