DEP: Day 455 And Counting: Seneca Resources Continues To Release Wastewater, Frack New Shale Gas Wells At Taft Well Pad In Middlebury Twp., Tioga County

On January 21, 2026, the Department of Environmental Protection inspected the Seneca Resources Co LLC Taft 851 shale gas well pad in Middlebury Township, Tioga and found evidence of wastewater spills continuing at the site.

Eight new gas wells were recently completed on the pad and prepping was underway to frack the wells.

Five other wells drilled and fracked since October 2024 were being staged for production.

DEP found “visible evidence of a release of material that overtopped the secondary containment structure” and contaminated liquid in secondary containment that had not been removed.

DEP also found erosion and sedimentation control measures at the pad and not been converted to post-construction best management practices to control runoff from the pad.

“DEP recommends that Seneca continues to monitor the conditions on the pad surface and the sediment basin and remove elevated conductance fluids and soils as discovered. Prevent elevated conductance fluids from leaving the facility and causing pollution to the waters of the Commonwealth.

DEP did not request a written follow-up to the violations.

These conditions have continued for 455 days at this well pad without abatement.

During a December 23, 2025 inspection found similar conditions-- spills, crews trying to clean up the pad while drilling new shale gas wells.

DEP issued the original spill violations at the site on October 23, 2024 and documented spills again during a July 11, 2025 inspection that were confirmed with water samples collected on August 21, 2025.

DEP found spills and releases during an October 2, 2025 inspection and one on October 31 making the same recommendations to monitor and remove contaminated water and soil..

Criminal Charges

Also on October 31, Attorney General Dave Sunday announced criminal charges against Seneca Resources, LLC, following multiple violations of Pennsylvania’s environmental protection laws in several counties, as recommended by the 48th and 51st Statewide Investigating Grand Juries.

Three separate criminal complaints were filed regarding the natural gas company’s violations related to improper waste management practices and policies.

Prominent in the Attorney General’s announcement of the charges was the fact that DEP repeatedly warned Seneca that their practices were not in line with Pennsylvania law, but those warnings were ignored or disputed.  Read more here.

In all, Seneca is charged with 64 counts of violations of the Solid Waste Management Act and 36 counts of violations of the Clean Streams Law in Cameron, Clearfield, Elk, Jefferson, Lycoming, McKean, Potter, Tioga Counties.  Read more here.
