CNX Gas Company Reports It Did Not Stop Pumping Shale Gas Wastewater Through A Punctured Pipeline For 24+ Hours During An Incident In Morris Township, Greene County In May

CNX Gas Company reported to DEP it did not stop pumping shale gas wastewater through a pipeline for 24+ hours after an excavator punctured an “unmarked” wastewater pipeline at the Coarse Coal Refuse Disposal Area 7 in Morris Township, Greene County.

On May 21, 2024, CNX notified DEP of a spill related to the McQuay to Morris 2 and 3 shale gas wastewater pipeline, as reported in PA Environment Digest. DEP May 21 inspection report.

The McQuay pipeline is near CNX’s MOR9 shale gas well pad on CONSOL’s underground Bailey Coal Mine surface property.

CNX initially reported that “more than a barrel” [42 gallons] of wastewater was released from a pipeline damaged by a contractor for CONSOL when an excavator doing earthwork at the coal refuse disposal area punctured an “unmarked” pipeline that runs under the disposal area.

In a June 21, 2024 response to DEP’s May 21 inspection report, CNX included a timeline of actions related to the incident that were known up until that time.

According to the timeline, the incident puncturing the wastewater pipeline happened on May 20 at 8:30 a.m.

On May 21 at 9:15 a.m., a CNX foreman received a voicemail that a contractor punctured the wastewater pipeline.

On May 21 at 9:34 a.m., CNX ceased all pumping of wastewater through the pipeline-- more than 24-hours after the pipeline was punctured.

On May 21 at Noon, CNX reported the incident to DEP Oil & Gas Program and CONSOL reported the incident to DEP’s Mining Office.

CNX said in its June 21 response, it had repaired 450 feet of damaged wastewater pipeline and excavated contaminated material was stockpiled for later removal.

CNX estimated removal of the contaminated soils would happen by July 5, 2024.

There was no estimate of the amount of wastewater released in the response.

The company said it would use the Act 2 Land Recycling Program standards for cleaning up the site.

Initial DEP Inspections

On May 21, DEP inspected the incident site in response to the CNX notification that same day and found “elevated conductivity” in “pooled water and substrate” at the impacted area.

At the time of this initial inspection, “CNX representatives noted that CONSOL had not called to check for buried lines in their work area since November of 2023,” according to DEP.

DEP requested CNX to submit a response to the violations resulting from the incident by June 18, 2024 with a description of how they would bring the site into compliance and an estimate of the amount of wastewater released. DEP May 21 inspection report.

In a follow-up inspection on May 28, DEP reported remediation work was continuing, but there were still areas with elevated conductivity.

DEP also found two new seeps of an “oil-like substance” in the spill area. DEP May 28 inspection report.

DEP said the wastewater pipeline was reburied and flagged at the time of this inspection.

No further inspection reports were posted by DEP’s Oil and Gas Program on this incident.

DEP’s Southwest Region Environmental Cleanup and Brownfields Program in Pittsburgh now has responsibility for overseeing the cleanup.

CNX Response To Violations

The June 21, 2024 response CNX Gas Company, Inc. sent to DEP took issue with the violations included in the May 21 inspection report.

CNX said it “disputes the allegation that it violated the provisions” of law and regulation cited in the notice of violation.

“This was an accidental line strike on CNX’s [wastewater] line committed by contractors engaged by CONSOL for land clearing and excavation work.”

CNX said its “investigation into the incident is ongoing, as of this date, CNX understands there were deficiencies in Pennsylvania 811 OneCall procedures undertaken by the contractors performing” the work in the months and weeks preceding the incident.

Notice Of Act 2 Cleanup

On October 17, 2024, CNX said it published a notice, as required, in the Observer-Reporter newspaper that it intended to use the Act 2 cleanup process at the incident site and submitted a Notice of Intent to remediate the site to DEP on November 14, nearly six months after the incident. (PA Bulletin-November 30, page 7704)

CNX said in the notice an “unknown volume” of wastewater was released.

The notice published in the PA Bulletin did not say which of the Act 2 cleanup standards the company planned to use.

Under Act 2, companies must submit documentation to DEP in a Final Report providing proof the cleanup they undertook met one or more of the Act 2 cleanup standards.
