BP's Olympic Pipeline, which leaked nearly 25,000 gallons of gasoline last week near Mount Vernon, Washington, has been restarted following repairs and regulatory approval, a source familiar with the pipeline's operations confirmed.

According to a Reuters report, Cleanup efforts, led by BP in collaboration with the U.S. Environmental Protection Agency (EPA) and local officials, have recovered nearly 7,000 gallons of spilled fuel as of Wednesday. The leak, attributed to a tubing failure inside a concrete vault, was detected and contained on Sunday.

The incident resulted in the death of at least one American beaver, one pine siskin bird, and one mallard duck, according to BP and the EPA. No gasoline or sheen has reached the Skagit River, and around 2,100 feet of containment boom remains deployed. State Route 534 has reopened to one-way traffic.

The incident comes on the heels of two major spills associated with BP: a 1999 pipeline rupture in Washington that killed three people and the 2010 Deepwater Horizon disaster, the largest oil spill in U.S. history.

BP's restart plan received regulatory approval after repairs and integrity testing deemed the pipeline safe for operation. However, the incident raises concerns about pipeline safety and environmental risks, particularly in light of the company's past history.

The EPA is expected to continue monitoring the cleanup and may impose fines or other penalties on BP depending on the investigation's findings.
