Per OAC 3745-20, the owner or operator of a demolition project must notify for all demolitions involving institutional, commercial, public, industrial, or certain residential structures, installations, or buildings. This includes bridges, tunnels, apartments with more than four dwelling units, homes which are part of a development project (not privately owned), partial demolitions, churches, power plants, parking garages, and farms.
Additionally, per OAC 3745-20, the owner or operator of a renovation project must notify when the amount of RACM stripped, removed, dislodged, cut, drilled, or otherwise disturbed exceeds 260 linear feet, 160 square feet, or 35 cubic feet off facility components. These amounts are a cumulative total of all work that is performed over the course of a calendar year.
Per OAC 3745-22, the owner or operator of a renovation project must notify when a licensed contractor is doing the project and the amount of RACM being abated exceeds 50 square feet or 50 linear feet.
Residential Exemption per OAC 3745-20: Projects involving a privately owned home, residential structures with four or fewer dwelling units, and mobile sources are exempt from having to submit a notification form, unless one or both of the following two conditions exist:
- More than one residential structure or private home is undergoing demolition as part of the same project.
- The demolition is being conducted using state and federal funds as part of an urban renewal project. If one or both of the above numbered conditions exist, privately owned homes, residential structures with four or fewer dwelling units, and mobile sources are required to submit a notification form.
However, there is no residential exemption for projects under 3745-22 when the work is being performed by a licensed contractor. In some instances, a project will be required to submit a notification per both OAC Chapters 3745-20 and 3745-22. The new combined Ohio EPA Demolition and Renovation/Abatement notification form covers both rules.
