On May 14, 2026, the Department of Environmental Protection issued a violation to Sandstone Development LLC for operating the McKay 7A conventional well as an oil and gas wastewater injection well in Lafayette Township, McKean County without a DEP permit.
DEP said records at the well showed 191,982 gallons of oil and gas wastewater had been disposed of at the well.
DEP previously inspected the McKay 7A well on January 20, 2026 and noted in the report Sandstone had a US Environmental Protection Agency injection well permit for the purpose of injecting wastewater associated with oil and gas production from Sandstone.
The January 20 report noted a wastewater storage tank was located at the injection well, but there was no activity on the site at the time of the inspection.
