Flaring work proceeds on February 7, 2024
On February 5, the Department of Environmental Protection announced it has begun an emergency project to plug two leaking abandoned natural gas wells along Scrubgrass Road in Scott Township, Allegheny County.
Two additional wells will be plugged in the same area using federal well plugging funds.
[DEP has been trying to get the operators of the wells– Economy Natural Gas Inc. and Michael Harju (who actually share the same address in Armstrong County)– to stop the gas leaks and plug the wells for nearly nine years, according to DEP inspection reports.
[According to DEP’s eFACTS database, Michael Harju operates 158 conventional wells, 13 of which are listed as abandoned and Economy Natural Gas Inc. operates 110 conventional wells.
[The four wells that are part of this announcement were listed as abandoned by DEP on inspection reports since the same date– April 14, 2015.]

At Gov. Josh Shapiro’s direction, DEP is aggressively working to plug leaking oil and gas wells across Pennsylvania using state and federal funds.
So far, under the Shapiro Administration, DEP has plugged 169 orphaned and abandoned wells.
[In 2023, DEP issued at least 512 notices of violation to 95 conventional oil and gas well operators for new or continuing well abandonment. Read more here.]
On Tuesday, February 6, 2024, DEP’s contractor will begin plugging two leaking abandoned wells [compliance history added]–
[– Nixon 501-1 (003-00960): The well is operated by Economy Natural Gas Inc. based in Spring Church, Armstrong County, according to DEP records.
[This well was listed as abandoned by DEP in an inspection report on April 14, 2015 (report not available), but it noted ‘no adverse event or action reported.]
[This well was listed as abandoned by DEP in an inspection report on April 21, 2016 (report not available).
[The well was inspected by DEP on October 1, 2017 and violations were issued, but the inspection report is not available.
[This well was inspected by DEP on January 29, 2018 and issued notice of violation for being abandoned (inspection report not available).
[A follow up inspection on March 14, 2018 ound the well abandoned and leaking gas. DEP’s inspection report did not record any follow-up actions.
[On July 29, 2020, DEP inspected the well in response to complaints it was leaking gas and issued notices of violations for that and for abandoning the well without plugging it. DEP’s inspection report gave the operator until September 1, 2020 to submit a plan for bringing the well into compliance. Obviously, it wasn’t.
[On March 17, 2021 DEP inspected the well and found it was leaking gas and issued notices of violation related to that leaking and for abandoning the well without plugging it. DEP’s inspection report gave the operator until April 12, 2021 to submit a plan for bringing the well into compliance. Obviously, there was no satisfactory response.
[On February 1, 2022, DEP received complaints about gas leaking from the well, including Allegheny County 911 calls. DEP’s inspection report said the “Department is working with the operator to address these recurring complaints.” No notice of violation was issued at that time.
[DEP began meeting with contractors on February 28, 2023 to solicit bids on plugging this well [DEP inspection report] and most recently on January 30, 2024 in a pre-plugging inspection [DEP inspection report].
[– Nixon 501-3 (003-00962): The well is operated by Michael Harju based in Spring Church, Armstrong County, according to DEP records.
[This well was listed as abandoned by DEP in an inspection report on April 14, 2015 (report not available), but noted ‘no adverse event or action reported.]
[This well was listed as abandoned by DEP in an inspection report on April 21, 2016 (report not available).
[This well was inspected on March 14, 2018 and found to be “leaking more gas than it did on previous inspections, but no violations issued in DEP’s inspection report.
[On July 29, 2020, DEP inspected the well in response to complaints it was leaking gas and issued notices of violations for that and for abandoning the well without plugging it. DEP’s inspection report gave the operator until September 1, 2020 to submit a plan for bringing the well into compliance. Obviously, it wasn’t.
[On March 17, 2021, DEP inspected the well and found it was leaking gas and issued notices of violation related to that leaking and for abandoning the well without plugging it. DEP’s inspection report gave the operator until April 12, 2021 to submit a plan for bringing the well into compliance. Obviously, there was no satisfactory response.
[DEP began meeting with contractors on February 28, 2023 to solicit bids on plugging this well [DEP inspection report] and most recently on August 15, 2023 [DEP inspection report].]
How Projects Will Proceed
DEP’s contractor will be removing trees and potentially flaring the wells in preparation for plugging. Flaring is the controlled burning of natural gas from a well and may be necessary to evacuate gas from the well to ensure it can be safely plugged.
The project is expected to take about a month to complete with a goal to permanently eliminate the potential for these wells to leak methane.
Due to the increasing methane levels, DEP has determined that this project is necessary to protect public health, safety, and the environment.
Without this emergency project, the well could continue to deteriorate and stray methane gas could migrate into nearby sewer lines through the soil.
The existing two leaking abandoned wells increase the risk of gas levels accumulating to unsafe levels if adverse weather conditions exist which would prevent the gas from dissipating. DEP will monitor stray gas while plugging the well.
DEP previously performed an emergency mitigation project in 2019 to address stray soil gas in the area.
Recently, methane levels around the wells increased, and DEP and Scott Township officials have received a number of odor complaints around the Kane Woods Nature Area.
“Orphaned and abandoned gas wells dot Southwestern Pennsylvania in rural and more populated areas, representing potential threats to human health, safety, and the environment. We’re mobilizing emergency crews to mitigate this hazard as quickly as possible.”
Director of District Oil & Gas Operations, Dan Counahan
DEP has allocated unprecedented resources to plug orphaned and abandoned wells, which allowed Pennsylvania to leverage millions in federal funding.
Two More Wells To Be Plugged
Two additional wells in this area are slated to be plugged later this year using federal Infrastructure Investment and Jobs Act (IIJA) funds.
DEP has been trying to get the operators of these wells to deal with continuing violations at these wells since April 14, 2015 [compliance history added]–

[DEP began listing the well as abandoned in an April 14, 2015 inspection report.
[DEP inspected the well on April 21, 2016, with results unknown (inspection report not available), but the well is listed as abandoned.
[DEP inspected the well July 12, 2017, July 17, 2017, August 1, 2017 and November 30, 2017, but no violations were noted.
[On March 14, 2018 DEP inspected the well and found it to be venting “a steady flow of gas.” No violations were issued.
[A DEP inspection report on October 7, 2019 noted the well “continues to vent a significant volume of gas that can be smelled in [the] valley.” No violations were issued or follow-up action noted.
[On July 29, 2020, DEP issued notices of violation for this well on abandoning the well without plugging it and for venting gas. DEP’s inspection report requested the operator to submit a plan by September 1, 2020 to bring the well into compliance. Obviously, it wasn’t.
[In a March 17, 2021 inspection, DEP said a “DEP-installed vent continues to vent stray gas from casing leak,” but obviously did not stop it. DEP’s inspection report continued previous violations.
[DEP began meeting with contractors on February 28, 2023 to solicit bids on plugging this well [DEP inspection report]. DEP last inspected the well on August 15, 2023 in the process of soliciting well plugging bids [DEP inspection report].]

Orphaned and abandoned oil and gas wells can leak methane, a potent greenhouse gas, that contributes to climate change.
Methane can migrate into buildings and water supplies. Pennsylvania has over 30,000 orphaned and abandoned oil and gas wells on its inventory and hundreds of thousands of legacy wells may be unaccounted for, posing a major financial liability and environmental, public health, and safety risk.
