Inspection Data

Inspections Performed

Inspection ID Inspection Category Inspection Date Inspection Type Inspection Result Inspection Comments
2375227 Primary Facility 2015-05-28 Preoperation Inspection No Violations Noted The Department was on site to conduct a preoperational inspection of the Chambers, M. well pad.
2381805 Primary Facility 2015-06-22 Routine/Complete Inspection No Violations Noted Arrived at the site at 11:30 to conduct a Follow-up inspection for an estimated 1.5-2 barrel spill of diesel based mud that occurred on 6/19/15. I was accompanied by Gene Rickard, DEP O&G WQS, during the inspection. We met with Marshall Hornsby, Site Company Man and Perk McDowell, Well Site Supervisor. Precision Drilling Rig #548 is in the process of drilling the Chambers 8H well at a depth 12,150 feet. Upon meeting with Mr. Hornsby and Mr. McDowell, we walked to the general area of the pad where the release occurred. We did not observe dark staining or compromised liner integrity in this area. Mr. Hornsby stated that the remediation process associated with the release was completed on 6/20/15. The remediation process consisted of an excavation of the impacted area of the pad surface near the oil based mud tanks at N-41.80275°; W-075.68135°, to a depth of 2 to 3 feet, and the use of absorbent pads to wipe the diesel based mud that had stained trailers and vehicles at the site.

2481929 Primary Facility 2016-05-06 Routine/Complete Inspection No Violations Noted On 5/6/16, the Department conducted an inspection of the COG Chambers O. Pad in response to the self-reporting by Cabot of a spill to containment at the well pad. During the inspection Larry Fulmer, Frac Superintendent for this site showed the Department where the spill occurred. The spill occurred on secondary containment for fracturing water which is itself located on the well pad containment. The containment appeared to be sound. A roustabout was vacuuming the containment during the inspection. Mr. Fulmer stated that the initial release of fluid to containment was probably around 1000 gallons of blended fluid and was identified when workers noted the excess water in the containment. They identified a poorly sealed port as the issue. While correcting and vacuuming up the spill, the workers identified an additional leaking seal on a separate tank, thus the additionally reported 500 gallon release to containment. This leak was also corrected and the spill cleaned up. No elevated conductivity reading

2497643 Primary Facility 2016-06-28 Routine/Complete Inspection No Violations Noted I conducted an inspection at the site accompanied by Joe Gaboff, DEP OGI. Shortly after arrival at 10:10, we met with Eric Bronson of Rain for Rent on the tank pad section of the site. Mr. Bronson stated the following information. "Flowback is currently in progress on the well pad. The flowback stated last Monday. The frac tanks in the tank farm on the tank pad contain flowback fluid from water from the wells on this pad. Trucks unload flowback fluid from the tanks and transport it to either Comtech or the treatment facility on Route 92. Comtech has not brought their mobile treatment unit to the pad to treat flowback water from the wells on this pad due to the fact the treatment facility on Rte. 92 is close to the well pad."

While in the process of inspecting the tank farm, Mr. Gaboff and I noticed that a section of the secondary containment berm was not in place in the tank farm on the west side of the tank pad near the site perimeter berm at N-41 48'15"; W-075 40' 48". The felt layer on top of the

2501857 Primary Facility 2016-07-06 Follow-up Inspection No Violations Noted I arrived at 11:45 AM to conduct a follow-up inspection of the tank pad of the site. I met with Jim, an employee of Rain for Rent on the tank pad. Rain for Rent is a subcontractor of Cabot. Their main job function at the site is to monitor vacuum trucks mobilizing to the site. These trucks offload fluid in frac tanks in the tank farm on the tank pad. The employee from Rain for Rent stated the following. "Only 1 truck has been at the site today to remove fluid from the tanks. The fluid will either go to Lenox or Comtech for treatment. The fluid in the tanks is flowback fluid from the wells on-site. There may be (70) frac tanks in the tank farm. There is a total of (26,300) barrels of fluid in the tanks. There may be some water left over from the frac and freshwater in the tanks."

The main intent of conducting the follow up inspection was to determine if the section of the containment berm that was not in place in tank farm on the west side of the tank pad near the tank pad perimeter berm during the

2585088 Primary Facility 2017-04-19 Routine/Complete Inspection No Violations Noted At time of inspection, arrived on site at 13:20p.m.

The cellar was about half full of water with no bubbling noticed. The (20x13) annulus vent pipe was open and venting into a small plastic tank, the (13x9) annulus vent pipe was open and venting into a small plastic tank, the (9x5) annulus vent pipe was open and venting into a small plastic tank. There was 627psi on the production casing. I took a walk around the location and there were no obvious concerns noticed. I left the site at 14:15p.m.

2690747 Primary Facility 2018-02-02 Routine/Complete Inspection No Violations Noted At time of inspection.

The well was in production. The (20x13), (13x9) and (9x5) annuli vent pipes were connected together and venting to the same tank. I took a walk around the location and there were no obvious concerns noticed. There were no violations noted.

2710856 Primary Facility 2018-03-22 Routine/Complete Inspection No Violations Noted Today's inspection was conducted as a routine inspection. No E&S issues identified. No violations noted.
2735996 Primary Facility 2018-05-30 Routine/Complete Inspection No Violations Noted Today's inspection was conducted as a routine inspection. No E&S issues were identified. No violations noted.
2760798 Primary Facility 2018-07-20 Incident- Response to Accident or Event No Violations Noted The Department arrived on site at 1125 hours to conduct a incident response inspection to investigate a self reported spill that occurred on 7/19 at about 0130 hours. The Department was represented by Frank Hoehle (WQS) and myself. On site representing Cabot was Steve Catalfamo (Senior EHS Specialist). According to Mr. Catalfamo, the incident transpired in the following manner:

While emptying the production fluid tank, a hose connecting a GDS vac truck and the coupling on the tank's water withdraw point failed, causing a release of production fluid to the pad's surface. The point of failure occurred in the middle of the hose, which is unusual according to Mr. Catalfamo, as hoses usually fail near the metal fittings on either end. The hose was fairly new, and did not appear to be in poor condition before the incident. However, due to the unusual spot on the hose where the failure occurred, Cabot believes that mechanical failure of the hose was at fault. The driver of the truck was quick to act, and immediate

2791399 Primary Facility 2018-10-18 Routine/Complete Inspection No Violations Noted At time of inspection.

The well was in production. There was water 7' below grade in the cellar with no bubbling noticed and there was no gas detected in the remainder of the cellar. The (13x9) and (9x5) annuli vent pipes were connected together and going to the same poly vent tank. There was gas detected at the poly vent tank. I took a walk around the location and there were no obvious concerns noticed. There were no violations noted.

2791436 Primary Facility 2018-10-15 Routine/Complete Inspection No Violations Noted I arrived on site at 1250 to conduct a follow-up inspection on behalf of the Department.

On 7/19, a release of production fluid occurred to the pad surface when the hose on a vacuum truck failed while emptying the production fluid tank. This incident is documented in inspection record #2755377.

The current inspection was performed to document the remediation efforts and provide a final confirmation that the site was indeed remediated. After inspecting the area, I agree that the site was remediated satisfactorily as documented in the operator response attached to the above-mentioned report. The violation may now be closed.

The Department concluded its inspection and left the site at 1320. No violations were noted.

2836112 Primary Facility 2019-02-04 Routine/Complete Inspection No Violations Noted Today's inspection was conducted as a routine inspection. Overall the site has good stabilization. No E&S issues identified. No violations noted.
