WEST CHESTER TWP. - A propylene gas leak in an industrial park caused officials to close off about one mile of Cincinnati-Dayton Road near Sharonville about 9:30 p.m.Thursday night.

There were no evacuations because there were no residences near the leak, township administrator Dave Gully said.

There were no injuries. Several nearby businesses were evacuated.

The leaks were at the AGA Gas Inc. facility at 10031 Cincinnati-Dayton Road and came after propylene tanks used in welding were overfilled and release valves began to release small amounts of gas. The gas is flammable and there was a risk of explosion, Gully said.

Hazmat crews responded as company personnel emptied the tanks.

Cincinnati-Dayton Road was closed from north of Crescentville Road to south of Gano.
