The state's attorney general, Xavier Becerra, said Thursday that inspections of Home Depot trash bins over a two-year span uncovered the violations.
The company said in a statement that it will work with California in its commitment to responsible waste disposal.
Becerra said the home improvement chain will pay about $16 million in civil penalties, $9 million toward environmental protection and compliance, and nearly $2 million to cover costs.
Officials say Home Depot outlets failed to properly manage the disposal of aerosol cans, batteries, electronics, paint and other items, in addition to customer information.
