In an effort to encourage San Diego County residents to sort their trash, recycling and organic waste correctly, the San Diego County Public Works (DPW) will begin inspecting waste bins in unincorporated areas starting next week.

Inspectors will lift lids on residents’ waste bins to check whether the top layer of trash is properly sorted.

If inspectors find an item in the wrong bin, they will place an ‘Oops Tag’ on the container as a reminder for residents to sort their trash correctly.

The DPW says the tags are meant solely as a reminder and do not carry a a penalty or fine.

County representatives will only scan items visible at the top of the bin without digging through the waste, the county added.

The inspections are part of California’s Senate Bill 1383, which aims to reduce organic waste in landfills.

Officials say the ‘lid flips’ are also intended to help protect the public and waste collection staff safe. Flammable materials such as propane tanks, lithium-ion batteries and other hazardous waste can cause fires or damage equipment, the county said.
