DEP: Second Spill From Horizontal Drilling At EQM Gathering Pipeline Construction Project In Washington County Contaminates Spring

On July 29, 2025, the Department of Environmental Protection inspected the
EQM Gathering OPCO LLC NINFS004 Pipeline construction project in Nottingham Township, Washington County in response to a July 28 complaint and a notification by the owner of a second “inadvertent return” spill from horizontal drilling.

EQM Gathering is a subsidiary of Equitrans Midstream Corp. that was recently acquired by EQT Corporation.

DEP said the pollution began in Froman Run from an unknown quantity of bentonite contaminated water just downstream of the pipeline crossing EQM was drilling under the creek.  

In addition, about 960 feet from Froman Run, DEP observed “numerous steady flowing bentonite laden deposits seeping out from the slope into an unidentified spring channel” and into a ditch beside a railroad track for about 550 feet until it dropped into an eroded drainage channel.

Attempts were made by EQM to contain the pollution with absorbent booms and seed mulch in the impacted areas.

New violations were issued for bentonite discharges into Froman Run and the ground polluting the spring and were documented in a three-part inspection report.

DEP requested EQM to document the amount of the spill and develop a plan for corrective actions and remediation of all areas impacted by the pollution.

A response was requested from EQM by August 15.  DEP inspection report- Part 1, Part 2, Part 3.

Second Spill

This is the second spill from horizontal drilling on this pipeline construction project.

On July 14, 2025, a routine inspection of the project in Nottingham Township by DEP found multiple erosion and sedimentation violations, turbid water being pumped from a pipeline bore pit to storage tanks that were overflowing secondary containment and erosion and sedimentation controls that were installed incorrectly. 

In other words the site was a real mess, so much so, DEP filed a three-part inspection report-- DEP inspection report Part 1, Part 2, Part 3.

DEP issued multiple violations and requested a response by August 6 on this spill.
