2491950	Primary Facility	2016-06-02	Routine/Complete Inspection	No Violations Noted	I conducted an inspection of the site accompanied by Scott Kuchta, DEP O&G WQS. Flowback operations were in progress as we arrived at 12:15 PM. Oil States Energy Services is the Chief subcontractor conducting the flowback. Shortly after our arrival, we met with Mason Hope, well tester, of Oil States. Mr. Hope stated the following information. "Flowback of the Clark unit 1H well started on 5/30/16. The well is making water and gas, with the gas being sent directly to sales. Thus far 3,000 barrels of fluid have been recovered at a rate of 40 barrels/hour. The fluid is sent to frac tanks on-site in a tank battery. Water from the sand trap is sent to the gas buster tank. A line heater and separate is used in the flowback process. The frac tanks were -site before the flowback started. The 3H well is in production. The 2H well has not been stimulated and is shut in." I recorded 3.7 milliSiemens/cm³ conductivity in water in the frac tank battery containment in the Northeast section of the pad. There were
