The developer of a 112-unit condo project in Woburn is seeking permission to install temporary and permanent propane tanks as the result of backlogs related to the six-month National Grid labor dispute.

Woburn-based Seaver Properties wants to install 11 large-capacity tanks as it redevelops the 46-acre Shannon Farm property at 299 Lexington St.

At a recent meeting, attorney Joseph Tarby told city councilors that six 1,000-gallon tanks would be housed above-ground, with another five permanent tanks installed underground, the Daily Times Chronicle reported. Fire Chief Stephen Adgate opposed the license. The Woburn City Council is scheduled to review the request again on April 16.

The development, known as Trouvaille, is marketing two-bedroom townhouse-style condos ranging from 1,300 to 1,800 square feet.

National Grid’s lockout ended in January. But backlogs related to the six-month labor dispute and a 10-week moratorium on non-emergency gas hookups following September’s Merrimack Valley gas disaster and an October over-pressurization incident continue to affect new construction hookups.

The Woburn city council denied a request from Boston-based Madison Properties in February for a 1,000-gallon propane tank at its Woburn Landing development site on Washington Street, to serve a planned Chick-Fil-A restaurant.
