A pipeline company was convicted of nine criminal charges Friday for causing the worst California coastal spill in 25 years, a disaster that blackened popular beaches for miles, killed wildlife and hurt tourism and fishing.

A Santa Barbara County jury found Houston-based Plains All American Pipeline guilty of a felony count of failing to properly maintain its pipeline and eight misdemeanor charges, including killing marine mammals and protected sea birds.

California Attorney General Xavier Becerra said in a statement that Plains’ actions were not only reckless and irresponsible but also criminal.

“Today’s verdict should send a message: if you endanger our environment and wildlife, we will hold you accountable,” he said.

Plains said in a statement that the jury didn’t find any knowing misconduct by the company and “accepts full responsibility for the impact of the accident.”

“We are committed to doing the right thing,” the company said.

The company said its operation of the pipeline met or exceeded legal and industry standards, and believes the jury erred in its verdict on one count where California law allowed a conviction under a standard of negligence.

“We intend to fully evaluate and consider all of our legal options with respect to the trial and resulting jury decision,” Plains said.
