Re: Oil Interceptor, Sentence 7.4.4.3.(2)

Project Description

The project in question is a new 32’ x 48’ detached garage/workshop serving a single family dwelling. The owner has proposed to install a floor drain in the building that would discharge to a dry well. The owner intends to do occasional vehicle repairs.

Reason for Appeal

Sentence 7.4.4.3.(2) requires the installation of an oil interceptor where the "discharge from a fixture (floor drain) may contain oil or gasoline."

Appellant’s Position

The appellant contends that the complication and expense of an oil interceptor is not warranted for private garage/workshop. If the code intended there to be oil interceptors wherever cars are parked they should be installed for storm drainage from all streets and parking lots.

Building Official's Position

The building official maintains that oil and gasoline may be present in a private garage workshop so the floor drain must discharge to an oil interceptor.

Appeal Board Decision #1568

It is the determination of the Board that an oil interceptor is required for the floor drain in the garage/workshop because oil and gas may be present.
