SOUTH PORTLAND (AP) — South Portland officials are in the process of developing a fire code amendment that would block a controversial proposal for a liquefied petroleum gas depot at Rigby Yard.

The Portland Press Herald reported (http://bit.ly/1RIuRfE ) city council on Monday ordered City Manager Jim Gailey to have municipal staff review a citizen-drafted fire code amendment proposed by Councilor Brad Fox.

The amendment requires propane storage and distribution facilities to be located at least 1,257 feet from anything considered “critical infrastructure.”

Among the things considered critical infrastructure are government buildings. The Cash Corner Fire Station is situated near Rigby Yard, the site for NGL Terminal Supply Co.’s proposed propane depot.

The Planning Board will hold a public hearing Tuesday to discuss a proposed six-month moratorium on the development of propane facilities.
