OAKLAND, Calif. (AP) — Retail giant Costco will pay $3.6 million for alleged environmental violations under a settlement with the district attorneys of more than two dozen California counties.

A Northern California judge approved the settlement Friday. It stems from a civil case brought by the district attorneys, who alleged Costco violated state laws for the safe storage, handling and disposal of hazardous waste, including pharmaceutical waste.

Prosecutors say the violations first came to light in San Joaquin County, but occurred from 2007 to 2012 at Costco stores and distribution centers across the state.

The $3.6 million settlement includes civil penalties, costs and funds for environmental projects.

Prosecutors say Costco officials were cooperative and quickly came into compliance with regulations.

A call to the company Monday wasn’t immediately returned.
