Compliance Agreements

The department has quarantined parts of Ohio to help stop the spread of Emerald Ash Borer (EAB) through materials that may harbor the destructive pest. It is illegal to take ash trees, parts of ash trees, and all hardwood firewood out of quarantined areas without a compliance agreement.

Businesses or individuals wanting to move or accept ash trees, parts of an ash tree, or hardwood firewood from quarantined areas must first have an ODA compliance agreement. These businesses must be willing and able to employ acceptable handling practices, as outlined in the signed agreement, that help ensure EAB is not inadvertently introduced to new areas. Compliance agreement holders accomplish this by removing and destroying infested parts of the tree and by restricting movement of quarantined materials to times of the year when the larvae are immobile under the bark.

If compliance conditions are violated, the agreement will be cancelled and the business may be subject to penalties. Officials regularly inspect approved facilities for continued compliance.
