A heating oil spill is being cleaned up at Panther Valley Middle School in Summit Hill.

The Department of Environmental Protection was notified at 8 a.m. today of the spill from a 10,000-gallon underground double-walled tank.

Approximately 5,000 gallons of heating oil was released from the tank. It appears the tank, but it is unknown how or why the tank failed, according to the DEP.

This tank is only seven years old.

The product seeped out of a bank and into the drain system at the bottom of the bank and behind the high school.

At this time there is no odor or Volatile Organic Compounds in the high school. The school complex is on public water and public sewer.

The tank is the same one that had a ruptured line in 2007 after someone drilled through the line causing 6,000 gallons to spill at that time.

Currently Datom Products, an environmental consulting and clean up contractor, is on site. A vacuum truck is being deployed to the school to empty the remaining product from the tank.

Datom plans to excavate the end of the tank towards the bank to facilitate free product recovery as well as to identify the breach in the tank. Datom will also be constructing an underflow dam near the end of the storm water collection system and before a wetland area.

An automatic skimmer will be installed at the underflow dam and recovered product will be placed in a tote for later disposal. There are currently monitoring wells located on the school property from a 2007 release that have not been abandoned.
