Spill Reports

Daybrook Development arrived at the Coastal AST site to offload production water into the Coastal AST. The driver hooked up to the ground manifold and started to pressurize the line, at which point the hose between the truck and the ground manifold failed, specifically at the cam lock connection. Approximately 1 BBL of produced water was sprayed onto the ground, outside secondary containment, but remained on pad. The driver immediately shut the truck off and removed all standing water with the truck.

Calls were made to supervisors, as well as the District WV DEP Inspector. NNE's first response environmental clean-up vendor was contacted and dispatched for remediation services.

DEP Inspector agreed with NNE's reactionary measures and said there was no need to call WV Spill Hotline.

At 10:15 AM, April 3, 2017, NNE found a failure in the tank containment on the Coastal Pad. The failure was a six inch cut in the containment, which allowed standing rain water to exit onto the pad - all water released remained on the pad. Notifications were made, the water was tested and results were within the allowable parameters, a sand bag was placed on top of the cut to reduce any additional water from escaping, and crews were dispatched. Daybrook Development was called to remove all remaining water from containment, and RW Products was called to patch the failed portion of the containment.

NNE's WV DEP Inspector was called to provide a summary of the incident, and no further direction was given.

Per Site Supervisor Glenn Boyd:
One of the Flynn trucks malfunctioned overnight and they made plans to switch it out today.
A replacement truck that was apparently not road legal showed up today on a Low Boy.
The Flynn Crew transferred the fuel from the lame truck into the replacement truck.
Then they loaded the lame truck on to the low boy and removed it from location.
The Flynn Crew then spotted the replacement truck near the blender. When the pump was kicked in the swivel connection on the hose started leaking. The crew stopped transferring fuel.
We stopped operations and the entire crew started containing the fuel.
Most of the fuel was on a secondary duck pond. A small amount was on the primary containment.
All the Fuel was contained and cleaned up.
Flynn will be replacing all the oil soak pads and removing the used oil soak pads from location tonight.
It is difficult to estimate the amount of fuel lost, but it may be as much as 40 according to Flynn.
Glenn,

During Line inspections today of the Temp Line Running from Coastal to Fisher location. I found a Diesel Spill coming from a Staged BJ Pump Truck. The Fuel has stoped leaking as of now, the Frac Consultant along with BJ was passed the information.

I just received word from the field that one of the water truck drivers from Ransom Drilling was killed as a result of his truck wrecking. I?m told as he was traveling on Rt. 50 to/from one the disposal facilities in Ohio, the truck blew a tire and he lost control. DOT is on scene and will conduct an investigation. There is a story already on WBOY?s website with two pictures, as well as WDTV?s website.

While performing our bore at the Jakes Run Stream Crossing we have seeped into the stream bed with our drilling mud. The mud finds a way to the surface from the bore. Bentonite is the only foreign substance in the mud. The stream is milky in color. I notified WVDEP inspector. Inspector Arrived on site at 2:10pm
Seep location was Identified. Our plan we presented to the inspector upon arrival as follows:
Build a temporary coffer dam above seep area with flume pipe. This construction practice has been approved per construction detail located on Sheet D10 of the approved NPDES plans. This is also acceptable with the ACOE due to ?discharges into waters are under 500? or 1/10th acre for each crossing? per email approval from the corps for the project.
The inspector is OK with this plan,as long as it was in the scope of our permit, coffer dam and flume will be built and operations will resume.
Hollie notified the spill hot line.

On 11/21/17 at approximately 4:15 PM and on 11/22/17 at approximately 2:00 PM, as crews were pressure testing the temporary, aboveground waterline between Coastal and Fisher, stress fractures were discovered during the line walks. These fractures allowed freshwater to be released onto the ground. Testing was immediately halted, the line was evacuated, and repairs were made and have been scheduled. The pipe that was delivered for this installation was used previously for other transfer jobs. QAQC was performed on the pipe prior to installation, but due to the nature of these impairments, they could not have been detected until pressure was applied to the line.

At 7:30 this morning a 16" temporary above ground waterline owned and operated by Rockwater, parted at a weld during frac operations on the Fisher Pad. The waterline operator had been pumping at 70 bbls/min for a couple of minutes when he noticed a drop in pressure and increase in flow rate. He immediately shut down operations to determine where the potential issue was. The break in the line was found above the Coastal Pad, along the access road that runs between the Fisher and Coastal Pads. We are estimating that 450 bbls of a 30% concentration mixture of produced and fresh water escaped and ran down the hillside and lease road. There are no streams or waterways that connect with the contaminated area. DEP inspector Gayne Knitowski was notifed at 9:00 am this morning, and visited the location. He was supportive of the actions we had taken and asked to be kept in the loop with the NGE plan of action for remediation. DEP spill hotline was contacted at 10:30 am and assigned the following reference number 31-67939. NGE has been brought in to address environmental remediation, and we are scheduling a meeting with Rockwater to address this incident.

On 12/13/17 at approximately 1:30 PM, NNE's drilling consultant observed water leaking at a flange on the discharge pipe at the AST. An estimated 2 BBL of blended water was released onto the ground, outside of containment. The water never left the well pad and did not impact any streams. NNE's HSE rep and Water rep went to site to assess situation and put containment under the leak to prevent further spreading. Water transfer crew members were immediately called to break down the flange and identify the failure. Upon breaking the flange down, it was determined the failure was a broken bolt that holds the flange together. Crew members replaced the damaged bolt with a new one, bolted the flange back up, which resolved the issue.

Diesel/water mixture under the mats most likely from an overfill of the boiler. A water truck had split the berming and was allowing the mixture to drip out onto the gravel, gravel was scooped up and disposed of and we began pulling mats to vacuum the liquid out from under them, extreme called out to repair section of containment.

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.

Moving around immobile equipment in tight space

The Skidsteer was non functional in the front of the drive over. The derrickman attempted to move around the skidsteer with the extend a boom forklift as he needed to get to the other side of location. The rear right tire tagged the 4" mud line going to the drive over causing the hose to separate at the crimped collar causing a 1 to 1-1/2 bbl spill. The ground below and around the spill was excavated to remove all contaminants.
