DEP: Contaminated Water Misting Out Of Storage Tank, Fluid Spill At Expand Operating, LLC Shale Gas Well Pad In Bradford County

On September 8, 2026, the Department of Environmental Protection was notified of a contaminated water release at the Expand Operating, LLC Deremer shale gas well pad in Tuscarora Township, Bradford County.

The well pad owner notified DEP on September 8 at 8:30 a.m. that on September 7 at 7:50 p.m. a mist of contaminated water was released into the air from a storage tank. Not reported was how long the misting might have been occurring.

The owner also said more contaminated water was released into and off secondary containment which looked in inspection photos to have a berm about 1 foot high around the tank.

The owner initially estimated the release was about 25 gallons.

[Note: If the owner had reported a release of 42 gallons or more, it triggers cleanup requirements under the Act 2 Land Recycling Program.]

“The cause of the release was due to the dump line being stuck open which was caused by a technical communication malfunction,” the owner reported.

During the inspection, the owner’s environmental consultant was delineating the area of contamination with field measurements and screening contaminating pad materials.  

A lined dumpster was onsite for disposal of the material, but remediation had not yet begun.

Photos sent to DEP after the inspection show a large area on two sides of the storage tank was scraped and contaminated material removed.

Multiple violations were issued, but DEP marked them “immediately corrected.”  No follow-up actions were requested
