The free, countywide event for Washington County residents to dispose of hazardous household and automotive goods without harming the environment or endangering human health is sponsored by several local companies and organizations, including the City of Bartlesville.
Each year, the event enables the safe disposal of more than 10,000 pounds of hazardous waste from the community for free. OCH was historically held on Earth Day but was rescheduled or cancelled in recent years due to the pandemic, but returns to Earth Day this year, on April 22.
