Spill Reports

Transferring produced water from the ASTs on the McClellan pad to the frac tank on the McClellan staging area in order to load out trucks.

AT APPROXIMATELY 3:07PM, ON APRIL 2, 2021, NNE WAS NOTIFIED THAT THE FRAC TANK AT THE MCCLELLAN STAGING AREA WAS OVERFLOWING. THE SELECT ENERGY SERVICES ("SES") HAND THAT WAS SUPPOSED TO BE OVERSEEING THE PUMPING AND TANK FILLING WAS DISTRACTED BY HIS PHONE AND ALLOWED THE TANK TO OVERFLOW. PRODUCED WATER WAS PUMPED INTO THE TANK TO THE POINT THAT THE TANK ITSELF OVERFLOWED INTO THE SECONDARY CONTAINMENT, THEN BREACHED THE SECONDARY CONTAINMENT AND WAS RELEASED ONTO THE GROUND, AN ESTIMATED 50 BBL WAS RELEASED ONTO THE GROUND. THE PUMP WAS IMMEDIATELY SHUT DOWN TO ELIMINATE THE SOURCE. WATER TRUCKS WERE DISPATCHED IMMEDIATELY TO EVACUATE ALL WATER FROM THE SECONDARY CONTAINMENT AND GROUND. E & S CONTROLS WERE PLACED IN ORDER TO MINIMIZE IMPACTS AND PREVENT FURTHER CONTAMINATION. NO STREAMS OR WETLANDS WERE AFFECTED BY THE SPILL. SES DISPATCHED MCCUTCHEON, AN ENVIRONMENTAL CLEAN-UP CREW, TO FULLY ADDRESS THE SPILL AREA. THE WV DEP INSPECTOR, BRYAN HARRIS, WAS NOTIFIED, AS WELL AS THE SPILL HOTLINE (REFERENCE ID 31-13410). MR. HARRIS VISITED THE SITE AND WAS HAPPY WITH THE STEPS TAKEN AND PLAN AHEAD. SES WILL BE COMPLETING A SPILL REPORT AND WILL SUBMIT.

Frac Operations on the McClellan 6H, 10H, 14H

Following up from prior report from unknown source of spill resulting in spill off containment on 2/10/21 at first was undetermined later was found to be SI SteamStream SC- 405. The leak originated on containment at a camlock on Scale line between scale ISO to blender. The camlock was not secured properly resulting in a slow leak of 600 gal of scale over the course of 12-24 hrs. The scale mixed with snow melt and rain water on containment traveled and collected at the low point of containment berm then leaking through 3 cracked seams in containment breching containment then collecting in standing water off containment. On 2/10/21 containment was cleaned and standing water directly affected off containment was picked up and desposed of in produced water tanks. A sump/trench was cut outside containment to collect and catch any residual that may accumulate. On 2/11/21 another 4-5 gal was picked up with vac truck that had accumulated over the course of 24 hrs. A 40'X70' section of containment was cut out and removed to inspect for any accumulation that could be traped under containment, no accumulation was visibly found. Containment repair replacing the removed section is underway and will be completed before moving removed frac equipment back on.

Cleaning up location after rig was moved out.

A heavy storm rolled in that seized cleaning operations on the Bunner pad. Upon leaving the site, Sam noticed soap bubbles forming in the ditchline along the lease road. Nothing was present on the pad, only the bottom half of the lease road & culvert. It appeared to be Dawn soap, which is used to clean the rig prior to a move. Its assumed that a truck load leaving location the prior days splashed some residual soap onto the blacktop lease road. The heavy downpour agitated the soap and made bubbles visible. The DEP inspector was notified. The following morning the soap suds were not visible.

Jeff was driving by pad when he saw the leak on the 3H and ESD'd the pad.

The Mepco 3H dump valve washed out and was leaking. Jeff Wilson was driving by when he saw the leak and ESD'd the pad. Nick Swartz and Matt Jones went to Mepco and saw that the dump valve had washed out. They replaced the valve and cleaned up the site. There was a small amount of produced water that got onto the ground. The DEP inspector was notified and the area was cleaned up and new material put down. The soil was also tested.

Rig crew instructed in the morning safety meeting to check equipment that needed to be capped and/or plugged. they men where told where their where caps, plugs and valves opened and to ensure the equipment was ready for transport prior to loading and hauling. The crew failed to ensure that the load and several others where road ready. The result was a 0.5bbl spill from the elk horn from a valve left open. The truck operated by Complete was loaded and hauling to Cummins from Matteo. The NNE company man, noticed drilling fluid along the top left side of the truck bed and wheels. The Company man inspected the truck and then headed up the lease road to find where the spill was located. The company man then took pictures, contacted NNE Drilling Engineer and went to Matteo to speak with the Patterson Rig Manager to make a plan for containment and cleaning.

A 0.5bbl spill occurred just off the Kassay Pad on the lease road heading down hill towards Cummins Pad due to the failure to properly inspect equipment prior to loading. Spill was contained and cleaned up quickly.

Conducting bi-monthly AST inspection.

While conducting the bi-monthly AST inspection, water was observed to be leaking on the outside of the AST and onto the ground. All water is within the AST's secondary containment and did not leave the site. The cause of the leak is undetermined at this time, until further investigation. The AST will be drained and the liner will be inspected for a failure. Once the failure is located, a repair will be made. If no failure is found, the liner will be replaced in its entirety.

Was notified of soap suds in run off water believed to be coming off the pad on a neighbors property. Went to investigate.

Upon skidding the rig this morning according to Decker drillings superintendent it is believed that the rig hands disconnected the mist pump lines on the containment. The mist pump lines contained soapy water. We had a torrential downpour. All water went to the back end of our containment which is the lowest point of the burm over flowing into the gravel. The max concentration soap to water is our mist tank is 30 Bbl's of fresh water to 2 gallons off soap. Corrective action was discussed with Deckers superintended, tool pusher and rig crew that anytime lines are disconnected they will be sucked out with the super sucker also additional catch pans will be place under the tote were soap is collected on the the containment.

Bear Contracting, who is building the Cummins Pad, stores the diesel fuel to refill their equipment on the Kassay Pad in a vessel. (The Cummins Pad entrance begins at the northern end of the Kassay Pad). Woodford, a subcontractor of Bear, was offloading diesel fuel with a fuel truck via hose into the vessel.

Summary of events occurred Monday, April 15, 2019.
Spill Area Approximately 10' by 10', 50 gallons, diesel fuel.
Tracy Davis, Bear Cummins Pad Superintendent, was not on the physical location of the fuel tank. When he contacted me at approximately 12:00 PM he informed me that the truck driver/delivery man for Woodford, a subcontractor of Bear Contracting, had let the on site fuel tank overrun during this mornings fill up. This occurred at approximately 11:15 Am. The secondary containment was either overrun or spray from the full vessel was discharged onto the Kassay well pad outside of the secondary containment for the vessel . (Visual estimation of 50 gallons). It is not known how much freeboard was available in the secondary containment prior to incident. It is believed that no fuels left the Kassay Well Pad containment per Tracy Davis. Mr. Davis indicted the driver for Woodford was not cooperative in providing any information regarding the incident. Mr. Davis is to provide a detailed report via email. Also, NNE employee Jeff Wilson, was on location during the incident. Please see Mr. Wilson's comments regarding the incident via email attachment. Also see photos post incident provided by Mr. Davis.

Re-fueling a portable heater unit.

"While re-fueling a third piece of equipment (a portable heater unit) the transfer / pump hose split and began to spray / release diesel fuel. The employee immediately shut down the pump and began to place spill pads to absorb the fuel. The fuel was on the bed of the truck as well as on the ground. Before the truck was moved it was cleaned to verify no additional areas would be affected. Approximately 2 - 4 gallons of diesel fuel was released (see attached photos). The spill area was cleaned up by placing the soiled spill pads and any dirt / rocks, that were affected, into collection buckets for disposal. The hose transfer line on the fuel cell was immediately replaced."

Crew was on the Coastal Pad removing solids from the AST, loading into vac boxes, and making ready for transport to disposal.

After the solids removal crew loaded one of the vac boxes, it was relocated from the work area to the staging area to wait for transport to disposal. As it was being unloaded from the roll-off truck to the staging area, the hatch door wasn't fully closed and allowed some of the solids/sludge to escape and spill onto the pad, outside secondary containment. The solids removal crew cleaned up the sludge and dressed in the area with new stone.

Operations of Wells

Daybrook was filling the heater with fuel and overfilled heater causing fuel to spill on ground.

No active task at time of notification of release.

On 9/16/18, at approximately 6:25 PM, NNE was notified by a landowner that water was overflowing an air release valve (ARV) vault and running down the hill. Landowner also notified WV DEP of the incident. NNE made notifications to supervision and dispatched field personnel to visually inspect the site and ensure the leaking had stopped. Once field personnel arrived at ARV site, water was still leaking and detected a one-inch drain valve was open on the bottom of the ARV. The valve was shut and the leaking stopped. Environmental contractor was called to bring erosion controls and gather water and soil samples to begin the remediation process. NNE personnel met with WV DEP Inspector, Gayne Knitowski, to review the site and discuss next steps. Remediation efforts will be ongoing until site is vacant of all contaminated material. Spill hotline was called and NNE was provided reference number 31-80825.
