(Sent an image to Steven Arauza.) The first occurance of the blue water was on the first of July. The property was experiencing issues with plumbing. The larger residence proceeded with a plumbing company to replace all plumbing fixtures, faucets, and piping (with a non-metal piping) as well as installing a filtration system and water softener. After replacing all of the pipes in the house the plumbers replaced the toilets as well. One of the plumbers noticed that the water in the back of the toilet was the light blue color. This was approximately the 25th of July. After the plumbers were done replacing the pipes, faucets, fixtures, and toilets, as well as installing the water softener and filters, the residence experienced the blue water again. This time the hose spigots were also opened and it was blue. This occurrence was August 13th. The well Permit Number is 60788-F and Receipt Number is 9501774. Resolution: Analytical results (received 9/6/2018) were non-detect for GRO, DRO, BTEX, and dissolved hydrocarbon gases (methane, ethane, ethene, propane). Overall water quality results for 8/22/2018 sample were consistent with samples collected on 1/9/2014 and 1/12/2015, indicating absence of impacts from nearby oil and gas activity. Water quality is compliant with CDPHE Human Health Standards and Secondary Drinking Water Standards.

  • Date Received: July 31, 2017 Document No.: 200443387 ONSITE INSPECTION REQUEST GARFIELD Operator: Ursa Operating Company Llc Facility: Monument Ridge Pad Description: Location: Monument Ridge Pad in Battlement Mesa. This pad is about 500 feet east of the junction of Stone Quarry Road and the south end of Monument Trail. Issue: I was riding a bicycle around the area of Monument Trail and Ponderosa Circle when I heard the sound of a large amount of gas escaping from a tank or pipe for about 30 seconds. I heard the loud hissing sound at least twice at about 8:30 p.m. At about 8:40 p.m., I was at the junction of Monument Trail and Stone Quarry Road, and I heard the sound of gas escaping (loud) about every 4 seconds. I called Community Counts about 10 minutes after hearing the sound of gas escaping. About 15 minutes after calling Community Counts, Nita Smith called me back and said that she had called John Doose at URSA and he was sending a worker out to fix the problem. The main reason I called was because gas pads usually do not make those types of noises and I thought there might be a problem. Resolution:

They acquired the construction contract for this work from Ursa Resources and are subject to the same conditions as was Ursa. Summit has been challenged by winter weather ever since they started so their schedules are likely off kilter, but they are only supposed to be operating between the hours of 7 am to 7 pm. We have been hearing noisy equipment sounds during very early hours of the morning, especially over the past two days. Someone should be communicating with neighboring residents so we know how long before this is corrected. Please investigate. Resolution: The location described in the complaint is not under the jurisdiction of the COGCC. The complaint was transferred to Garfield County LGD. The complainant was notified of the transfer and provided contact information for the LGD.

Complainant has spoken with John Doose, Ursa and Garfield County LGD Kirby Wynn. I woke at 1:46 am Nauseous it was the air I was breathing my swamp cooler was running it was the odor of the nasty gas from URSA with a twist of something mixed with it to disguise the smell. Ursa had told us they were going to mix stuff with the odor to disguise the smell. I left my house after I made a few calls and the nauseousness went a way. I drove up by their pads and there was a tanker truck a entering the pad. I have smelled odors in the night recently but it was a bit different type of smell which I assume was from URSA with their disguising method I came back home at 2:25 am and the smell was gone. Resolution: On 07/13/2016 COGCC Inspectors Curtis Conklin and Richard Murray conducted an inspection of the Yater Pad (documented in FIR #675203033, attached); Mr. Conklin and Mr. Murray did not identify a source of odors at the time of the inspection, but did speak to an employee on the location about the loading process for removing produced water from the production tanks; On 07/14/2016 Mr. Conklin and COGCC Inspector Shaun Kellerby conducted an additional inspection of the Yater Pad (documented in FIR #675203040, attached); Mr. Conklin and Mr. Kellerby inspected production tanks, well heads, and separators and noticed odor at northeast corner of location. The inspectors visually and audibly detected a release from Pressure Vacuum Relief Valves above condensate tank in the southeast corner of the containment. A FLIR camera was used to capture the release at the time of the inspection; FIR #675203040 was issued with action required to “securely fasten all valves, pipes, and fittings to ensure good mechanical condition per Rule 605.d.” and “Provide COGCC FIU with documentation of equipment specs and maintenance” by the corrective action date of 07/16/2016; and On 07/18/2016 Mr. Conklin conducted a follow-up inspection at the Yater Pad (documented in FIR #675203048) and observed that corrective actions from FIR #675203040 had been completed.

  • Date Received: May 16, 2016 Document No.: 200439545 PROPERTY DAMAGE GARFIELD Operator: Mustang Resources Llc Facility: PEARSON Description: ,Mustang Energy sub contracted a chemical spraying company and authorized them to spray a chemical on the well site. The surface agreement with Mustang specifically states that they will not spray any chemicals on the property without first notifying the landowner. They have not notified me and now I have an area about 100ft by 100 ft. in my pasture that all the grass is dead. I have irrigation water and need to irrigate my pasture by I do not know what they sprayed and if it is a leachable chemical will more damage by done if I irrigate. This continues Mustang Energy bullying attitude towards land owners and is typical of how they operate agreements mean noting to them they do as they please and have no regards for the land owner. It is not there land they are only occupying it for the time the well is there, they have no right to spray chemicals on my land. I want the land restored as it was before the spraying was done. I have always maintained my pasture area to prevent the possible fire damage to the well as you investigator will be able to see the area was mowed prior to the spraying by me and is kept that way. Resolution: The COGCC determined that no violations occurred related to this complaint.

Vent has never been serviced or checked by the oil and gas company for more the 20 years. The line that the vent is on I belive is from Savage Well 26-32 and connects it it Moore well 27-42 and Pearson well 26-12. Had a very hard time finding the gas company even visited the COGC office in Rifle and they could not fine the pipe line ownership. I was informed by Vaquero Energy 4700 Stockdale Highway Suite 120, Bakersfield, California 93309 that they were shutting down the gas wells in the in Dec. of 2015 since that time the vent (grasshopper) has stop dripping hydrocarbons, and releasing strong hydrocarbon odors to the air, so I am assuming that Vaquero Energy is the owner of the pipe line. I talk with the Garfield County Oil and Gas Liaison officer Kirby Winn about the situation but he was not able to help me since I did not know the owner of the pipe line. Soil has been contaminated around the vent and possible all the way down to the creek. Resolution: COGCC staff determined that a pipeline was leaking and Spill/Release Point ID 445103 was created. The operator (Mustang) submitted Form 19 spill reports (doc # 401002474, 401041875). Mustang submitted remediation work plan (doc #2526043 (REM #9598). COGCC staff conducted oversight on remediation and confirmation sampling and closed REM 9598 with approval of Form 4, Document Number 401054461. A warning letter was issued to Mustang Document # 2193355.

Noble owns and operates 9 wells and the tanks, separators and pipelines on the pad which support production from the 9 wells. Chevron is filing this complaint to formally advance its concern that the subsiding cut slope on the subject pad will continue to deteriorate, and in the event of a failure, could pose a serious risk to human health, safety, and the environment. Chevron requests immediate COGCC review of the location, weather permitting, so that Chevron’s concerns can be addressed and a plan of action and timeline of completion can be discussed. COGCC Inspector Curtis Conklin inspected the well pad on 23 September 2014 and noted several “Action Required” items, including correction of the cut slope subsidence, on the Field Inspection Form (Doc. No. 675200585). The inspection form directed Noble to use BMPs to address and correct the subsidence of the cut slope by 23 October 2014 and file a Form 42 when the corrective actions were complete. Noble filed a Form 42 (Doc. No. 400712926) stating that corrective actions required by the 23 September inspection document were performed on 20 October 2014. Chevron subsequently visited the pad, but could not determine the status of the cut slope due to snow cover. Chevron received a statement from Noble in January 2015 claiming that all “Action Required” items listed on the above-cited inspection form were corrected. Chevron representatives visited the subject well pad in February and June 2015 to determine if the cut slope subsidence had been repaired, but it was apparent during each visit that Noble has failed to comply with COGCC directive.

This well has traffic coming in after dark and the noise and headlights are distracting. It also bleeds off and makes a terribly loud hissing noise. We have horses and cattle and this noise is startling to horses and could get a rider in serious trouble if the horse spooks badly. Also a bit unnerving since this well has blown up on us previously and they have still not reimbursed us for the lost hay they had to pick up. The operator at this location is Bayswater. Complainant has contacted Mark Brown of Bayswater in regards to some issues on the closest well. This appears to be location # 432327 (Triangle 6-22).

Pit is unlined. Sometime between evening of Thursday 1/26/2012 when skelton crew left and the morning of 1/30/2012 when they returned, someone had dumped mud of some sort into the unlined DeJour pit. The dumping was not authorized. Field folks reported to Kenny Monday afternoon. DeJour checked with Williams/WPX personnel nearby (Williams/WPX has two pads in vicinity) and Williams/WPX folks said it was a mistake by their truck. Kenny reported that he spoke with Williams/WPX drilling superintendent who reported it was drill fluids from around a well head, but Kenny said his sample is starting to set up, becoming chalky/powdery. Initially looked like cement, but no cement-like or other odor. Resolution: Sundry with drilling waste and pit bottom sample results submitted 2/15/2012 (Document # _____)Arsenic in pit bottom is higher than arsenic in waste that was dumped (see drilling waste sample results) and within the range of background arsenic concentrations observed in this area, thus the arsenic level appears to be background. Ph is pit bottom is above Table 910-1 levels, but pit bottom is greater than 3 feet below ground surface so below the root zone. Ec and SAR are below Table 910-1 levels.

  • Date Received: Aug. 4, 2011 Document No.: 200317056 NOISE GARFIELD Operator: Encana Oil & Gas (Usa) Inc Facility: Benjamin Fee Description: Linda, I would like to take this opportunity to share with you some of the frustration I am having with Encana. Recently Encana approached me with the desire to run a temporary water line down my property. I met with their land man and we negotiated a deal and came to and agreement in the form of a contract. The team assigned to the task was very interested in the improvement of the image that Encana has locally. We started out working together and I actually thought at that point that they were doing a good job in improving public relations. As they were completing some of the work that was associated with our agreement I met them and we discussed making a few modifications to the work that they had in place to which they agreed. A few day later I reviewed the work that they had done and frankly, they had made a mess of it. I reached out to them and was basically told “too bad” nothing we can do at this time. I had also requested that the lighting that they had installed for the frac operations was pointing at my home and as such could they please realign them to point at the pad. I was informed that they did the best they could. I will attach some photos. I can also forward you the emails I sent to David Grisso at Encana regarding these issues if you like. No realignment has taken place nor have any of the issues been addressed. You will note in the photos that the lights are clearly aligned right at my home, not at the pad where the work is taking place. The light pool of the night time shots will indicate that the lights only illuminate one small corner of the frac tanks and is pointing right at me on my deck. It had been my hope that the “new” Encana was going to step up and do the right thing. However, I have gotten very little response in terms of the issues and nothing has been done regarding the fugitive light. Thus, I am writing to you to see if you can help me to resolve these issues as the governing body of the gas industry. The major issues are as follows: • One of the light plants at Resolution: .

Odors were described as sewer odor until 2007 at which time it went away. In 2008 a new odor was described as gas smell. Complainant believes that the changes in odor correspond with drilling of nearby gas well. A radon mitigation system was recently installed over sump in basement and odor has subsided. Complainant is still concerned that gas could be getting into basement and is now being vented outside towards neighbors houses. Several other houses in development have had similar problems.

He is Rob Regulski (970-876-2675). He owns land at the frontage road and Divide Creek Road and Antero has an easement for a pipeline across his property, along the road. His concern that involves OGLA folks is that the pipeline leads to a wellpad (McLin A) which is adjacent and uphill from his property. He was notified by Antero, via letter, that per Rule 305, he may submit comments concerning the permit application. He is not certain how to do this. Mr. Regulski states that there is an unmapped ditch (Ward-Reynolds Ditch) that Mr. Regulski is majority owner of that goes along hillside between the proposed pad and his property. He believes that the ditch and Antero’s pipeline are in jeopardy, and would certainly be impacted by anything flowing downhill. The entire area is in 315B buffer zones, it appears to be partially in intermediate buffer, definitely outer buffer zone. Rob provided a copy of the 2A, which has ‘current land use’ marked as Rangeland; Rob states there are historic water rights to the property and it should be marked as irrigated for both current and future use. The 2A also reports that is not in a sensitive area, yet nearest surface water is within 170 feet ;and it’s in a 317B zone(s).

He stated that no interim reclamation has taken place and that the location was not adequately designed and constructed with respect to surface disturbance minimization and unnecessary alteration of natural features, of which steep vertical cuts have resulted in cumulative impacts. Resolution: COGCC inspected the Dixon B Federal well pad on June 6, 2010, and also July 27, 2010 and are documented in field inspection report #s 200263751 and 200265070 in the COGCC database. A letter detailing the field observations and requirements has been sent to the complainant and Antero Resources, and is summarized below: Presently, there is no violation of Rule 1003.b, due to the following: There are current (un-expired) APDs at this location, hence, the statutory time frame for commencing interim reclamation (Rule 1003.b.) of areas no longer in use, or reasonably needed to sustain operations, have not elapsed. Also, re-vegetation in “progress” was observed along the fill slope and near the location entrance. However, it was observed that the cut slope requires BMPs for erosion control, and that the lease road and associated BMPs require periodic inspections and maintenance, per Rule 1002.f. Antero has been notified to correct the issues via telephone, email, and letter correspondence. COGCC will continue to inspect this location to ascertain effectiveness of BMPs.

  • Date Received: May 25, 2010 Document No.: 200251777 RECLAMATION GARFIELD Operator: Dolphin Energy Corporation Facility: BISCUIT RANCH Description: While conducting a field inspection for the Dolphin Energy Biscuit Ranch 10-31D pad, (COGCC Location #335714), I was approached by Mr. Nathan Bell, who manages and also leases the land which incorporates the referenced location for cultivation. The owners of the property are Bryce’s Valley Holdings, based in Taos, New Mexico. He specified that little to no reclamation efforts have been performed by Dolphin Energy and that he has been unsuccessful in contacting and locating operator personnel. Hence, Mr. Bell has been left with the tasks of maintaining this well pad in addition to other pad locations which have been abandoned by Dolphin Energy. Field observations and review of aerial photos and COGCC records indicate that the well pad and access road are within irrigated cropland, and that no vegetative reclamation has taken place. One wellhead exists on location and has been temporarily abandoned since July of 2008 (Document #1808248). In addition, the field inspection confirmed the existence of two additional oil and gas construction areas within a 1/4 mile northeast of the above-referenced location and consists of the following: a compacted and graded pad that has abandoned drilling equipment and associated materials, and to the north, the excavation site which appears to have been utilized as the earthen infill material for the construction of the Biscuit Ranch 10-31D pad. Refer to COGIS Field Inspection Report, Doc. #200247531, for further information. Resolution: For further information regarding the Dolphin Energy Biscuit Ranch #3 pad (ID 324370), refer to NOAV document #200263730 and field inspection document #200247765. For further information regarding the Dolphin Energy Biscuit Ranch #31 pad (ID 335714), refer to NOAV document #200263731 and field inspection document #200247531.

  • Date Received: April 30, 2010 Document No.: 200245515 ACCESS GARFIELD Operator: Encana Oil & Gas (Usa) Inc Facility: GMR-66S93W Description: Rifle office received a complaint from Clint and Janet Sheridan (surface/land owners) regarding poor interim reclamation of unused areas on the G33NW Pad, located in the Grass Mesa Subdivision. Issues of concern include insufficient top soil, unsuccessful seeding, and poor surface land contouring. According to the Sheridans, Encana did respond to their complaint, and have re-assigned a different contractor to rework surface contouring and other reclamation activities as assigned. According to Mrs. Sheridan, recent reclaim activies appear to be adequate. However, they are requesting for COGCC to inspect the subject pad and monitor progress, so that interim reclamation work is not neglected. Resolution: Based on the inspection it appears that EnCana is in compliance with COGCC interim reclamation and stormwater requirements. Additional items were inspected and no violations of COGCC rules were identified. Based on these results the COGCC will close this complaint and no enforcement actions are planned. The COGCC will continue to monitor the progress of reclamation at the G33 NW. COGCC's response letter to the complainants dated May 21, 2010 was issued.

Lisa lives between these two land owners and has had impacts previously on her property. On 4/23/2010 Lisa took EPA, Garfield County and COGCC representatives on a driving tour from Dry Hollow Road and 6500 Road intersection to the eastern edge of West Divide Creek on her property. Lisa reported that several water wells in the area were ruined when the Arbane kick occurred on the P3 pad on March 9, 2004 (referred to below as the Arbaney event) and that multiple stock ponds had bubbles coming up in them. Lisa thinks the Arbaney event possibly exasperated or increased the fracture network subsurface as residents felt an the earth moving when that event occurred. Lisa reports that the ridgeline between the Sherowski's property and the Thompson's property dropped in elevation as a result of the Arbaney event. Lisa reports that the water well and surface water impacts follow basically a linear path from P3 to the West Divide creek seep area from 2004 and 2008. Lisa expressed frustration that all timelines she’s seen begin in April 2004 and go forward, and do not include this significant kick at the Arbaney well which occurred on March 9, 2004. Lisa feels that COGCC always compartmentalizes, minimizes, and isolates events from each other, rather than looking at the big picture. She feels the Arbaney event precipated or set the stage for all the other events and that they are interrelated, not isolated from each other and should be investigated as a whole.

Rick reported that PDC had a spill/release today at approximately 8am. Rick reported that liquid was discharging from a 4” pipe at the base of a Rain for Rent storage tank (big, square tank) for about 20 minutes. Rick estimated that more than 20 gallons were released. Rick reported that it puddled in the road and ran down the road, but he said it did not make it all the way to the creek. Rick collected a sample of the liquid, however it is unknown if it was from the discharge or from one of the puddles in the road. The sample was collected in an 8-oz Kerr jelly jar, which Rick said was clean from the kitchen of his house. The jar contained about 7 oz of liquid with lid and ring in place. Jay Krabacher smelled the liquid in the jar and said it had a hydrocarbon and shoe-polish type odor to it. Rick reported that Tony Barrientos, PDC Completion Supervisor Western Rockies told him that the liquid was “fresh water from the creek”, which Rick does not believe. Rick reported that the release was shut down after about 20 minutes of discharge and PDC built berms to contain the spill. Rick had Anthony’s business card. Rick does not seem to believe PDC will sample and report honestly. Rick stated that "Tony lied to him about the contents of the tank". Rick took his sample with him, stating it was insurance and was going to put it in his cooler to keep it cool. Jay and I pulled up the COGCC map and had Rick locate the well in question to the best of his ability. Rick indicated it was at the center of Section 17, 6S 96W. The well located where Rick indicated on the map, is PDC well Chevron 22D-17, API number 05-045-14738.

Document No.: 401541465 Rule: 324A.a Rule Description: General Environmental Protection Alleged Violation Description: Pursuant to Rule 324A.a., Caerus Piceance LLC (“Caerus”), shall take precautions to prevent significant adverse environmental impacts to air, water, soil, or biological resources to the extent necessary to protect public health, safety and welfare, including the environment and wildlife resources, taking into consideration cost-effectiveness and technical feasibility to prevent the unauthorized discharge or disposal of oil, gas, E&P waste, chemical substances, or other oilfield waste. On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state (COGCC Spill/Release ID 451556). Caerus determined the cause of the spill to be an inadequate fuse between two pieces of the polyethylene pipeline (Spill/Release Supplemental Report, Document No. 401372750). On August 7, 2017, COGCC Staff conducted an environmental field inspection and observed the E&P waste flow path, the replaced pipeline segment, and the ponds into which the E&P Waste fluids discharged (Inspection Document No. 689100030). Caerus estimated a volume of 500 bbls of an Exploration and Production (“E&P”) Waste mixture of fresh and produced water flowed downhill following the pipeline path and entered a dry natural drainage. Farther down the drainage, the E&P Waste directly impacted surface water and two ponds in a series of four ponds fed by stormwater and by a nearby spring. Caerus placed oil absorbent booms and pads along the spill path; and pumped the water from the uppermost pond, waited for the pond to refill partially (from the spring), and pumped the pond dry again. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423) Caerus failed to take the reasonable precaution of correctly butt-fusing the polyethylene pipeline, in violation of Rule 324A.a. This inadequate fuse spilled E&P waste such that Caerus had to remove two pond volumes of surface water in their effort to remediate the environmental impact of the spill. Enforcement Action: Corrective Action Description: Caerus will submit to COGCC a written plan detailing operational and engineering procedures to prevent recurrence. The plan shall include correct butt-fusing procedures for polyethylene pipe, Quality Assurance & Quality Control (QA/QC) procedures for pipeline installation, pressure testing requirements and procedures for temporary pipelines, personnel and contractor training requirements, and management procedures and responsibilities.

Document No.: 401541465 Rule: 324A.b Rule Description: Water Quality Alleged Violation Description: Pursuant to Rule 324A.b., in the conduct of any oil or gas operation, Caerus Piceance LLC (“Caerus”), shall not perform any act or practice which constitutes a violation of water quality standards or classifications established by the Water Quality Control Commission for waters of the state. On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state, including both groundwater and surface water (COGCC Spill/Release ID 451556). On August 7, 2017, COGCC Staff conducted an environmental field inspection and observed the E&P waste flow path, the replaced pipeline segment, and the ponds into which the E&P Waste fluids discharged (Inspection Document No. 689100030). Caerus estimated a volume of 500 bbls of an Exploration and Production (“E&P”) Waste mixture of fresh and produced water flowed downhill following the pipeline path and entered a dry natural drainage. Farther down the drainage, the E&P Waste directly impacted surface water and two ponds in a series of four ponds fed by stormwater and by a nearby spring. Caerus sampled the soil along the spill path and surface water from the ponds and downstream. This sampling indicated exceedances of Table 910-1 and Water Quality Control Commission Regulation #37 Stream Classification and Water Quality Standard, Lower Colorado River. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423; Sampling Analytical Results, Document Nos. 401372986 and 401375431). Caerus spilled E&P waste into waters of the state, which resulted in a violation of WQCC water quality standards, thereby violating Rule 324A.b. Enforcement Action: Corrective Action Description: Caerus shall submit to COGCC a Form 27 – Site Investigation and Remediation Workplan containing and implementing plans for the following: 1. Semi-annual sampling along the path of the spill from the spill site to uppermost pond until soil EC levels comply with Table 910-1. 2. Quarterly surface water sampling from pond inlets and outlets until chloride and TDS levels comply with WQCC water quality standards and Table 910-1 in consideration of background concentrations established at Pond 3 Inlet on 7/29/1, at least through December 2018. 3. A sensitive area determination according to Rule 901.e. Final Resolution Comment:

Document No.: 401541465 Rule: 907.a Rule Description: General E&P Waste management Requirements Alleged Violation Description: Pursuant to Rule 907.a., Caerus Piceance LLC (“Caerus”) shall (1) ensure that E&P waste is properly stored, handled, transported, treated, recycled, or disposed to prevent threatened or actual significant adverse environmental impacts to air, water, soil or biological resources or to the extent necessary to ensure compliance with the concentration levels in Table 910-1, with consideration to WQCC groundwater standards and classifications; and (2) conduct E&P waste management activities, and construct and operate facilities, to protect the waters of the state from significant adverse environmental impacts from E&P waste, except as permitted by applicable laws and regulations. On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state (COGCC Spill/Release ID 451556). On August 7, 2017, COGCC Staff conducted an environmental field inspection and observed the E&P waste flow path, the replaced pipeline segment, and the ponds into which the E&P Waste fluids discharged (Inspection Document No. 689100030). Caerus estimated a volume of 500 bbls of an Exploration and Production (“E&P”) Waste mixture of fresh and produced water flowed downhill following the pipeline path and entered a dry natural drainage. Farther down the drainage, the E&P Waste directly impacted surface water and two ponds in a series of four ponds fed by stormwater and by a nearby spring. Caerus placed oil absorbent booms and pads along the spill path; and pumped the water from the uppermost pond, waited for the pond to refill partially (from the spring), and pumped the pond dry again. Caerus also sampled the soil along the spill path and surface water from the ponds and downstream. This sampling indicated exceedances of Table 910-1 and Water Quality Control Commission Regulation #37 Stream Classification and Water Quality Standard, Lower Colorado River. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423; Sampling Analytical Results, Document Nos. 401372986 and 401375431). Caerus failed to manage E&P waste in a manner to protect waters of the state such that Caerus had to pump the pond dry twice in their effort to remediate the environmental impact of the spill, and the spill resulted in a violation of WQCC water quality standards and Table 910-1 concentration levels, thereby violating Rule 907.a. Enforcement Action: Corrective Action Description: Caerus shall submit to COGCC a Form 27 – Site Investigation and Remediation Workplan containing and implementing plans for the following: 1. Semi-annual sampling along the path of the spill from the spill site to uppermost pond until soil EC levels comply with Table 910-1. 2.

Document No.: 401733750 Rule: 1002.f Rule Description: Stormwater Management Alleged Violation Description: Pursuant to Rule Caerus Piceance LLC (“Operator”) shall implement and maintain Best Management Practices (“BMPs”) at all oil and gas locations to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation; and shall maintain BMPs until the facility is abandoned and final reclamation is achieved pursuant to Rule 1004. Operator shall employ BMPs, as necessary to comply with this rule, at all oil and gas locations, including, but not limited to, well pads, soil stockpiles, access roads, tank batteries, compressor stations, and pipeline rights of way. BMPs shall be selected based on site-specific conditions, such as slope, vegetation cover, and proximity to water bodies, and may include maintaining in-place some or all of the BMPs installed during the construction phase of the facility. Best Management Practices indicate that Operator shall implement such protection upon commencement of construction. On October 22, 2015, Operator submitted an application for Oil and Gas Location Assessment to amend the existing 20F Pad (ID 414880, “Location”) (Document No. 400913858, “Form 2A”). Location is an expansion of an existing location and is within a sensitive wildlife habitat area. COGCC approved Operator’s Form 2A on December 18, 2018, with a condition of approval (“COA”) including the following requirements: “The Location is in an area of moderate to high run-on/run-off potential; therefore standard stormwater BMPs must be implemented prior to, during, and after construction; as well as during drilling, completion, and production operations; at this Location to ensure compliance with COGCC requirements and to prevent any stormwater run-on and /or stormwater run-off”; “The access road will be maintained as to not allow any sediment to migrate from the access road to nearby surface water or any drainages leading to surface water.”; and “Run-on protection and run-off controls will be installed prior to the beginning of construction activities, as practicable, with consideration given to worker safety, wildlife, and site access.” On September 5, 2017, Operator submitted a Form 42, Notice of Construction of Location, to notify COGCC of the September 9, 2017, intended start of construction of the 20F Pad (ID 414880, “Location”) (Document No. 401395038). In response to a complaint of property damage due to inadequate stormwater controls at the Location received May 1, 2018, (Document No. 200445816), COGCC Staff inspected the Location that day and observed that sufficient BMPs had not been installed; those BMPs in place were ineffective and had not been maintained or repaired in accordance with good engineering practices. COGCC staff observed erosion and sediment migration throughout the location including the fill and cut slopes. The erosion included movement of sediment, gravel, and cobbles that moved down the unstabilized slopes. Slash and other debris had been pushed off location. Stormwater BMPs appeared to consist of straw wattles at limited locations at the base of the fill slope. The wattles were not installed properly, nor were they used in a correct situation, and have not been maintained. Sediment deposition including silt, sand, cobbles, and boulders are moving off the fill slope and onto previously undisturbed surface areas that should not have been disturbed. Fill slopes were not stabilized. Structures that appear to have been intended to be stormwater BMPs have been overwhelmed by sloughing of sediment, gravel, and cobbles from the fill slopes. These structure Enforcement Action: Corrective Action Description: Operator shall install or repair BMPs as indicated in Field Inspection Report No. 666801621; including, but not limited to: stormwater wattles, retention ponds, ditches, berms; and as needed to allow and protect access throughout the length of the access road as it intersects with potential runoff or erosion from the Location. By the corrective action due date, Operator shall submit an eForm 4 Sundry Notice which documents Operator’s actions to install and maintain adequate stormwater controls throughout the Location, and includes photograph evidence of corrective action completion.

Document No.: 401733750 Rule: 1002.b Rule Description: Soil Removal & Segregation Alleged Violation Description: Pursuant to Rule 1002.b.(2), as to all excavation operations undertaken on non-crop land, Caerus Piceance LLC (“Operator”) shall separate and store the topsoil horizon or the top six inches, whichever is deeper, and mark or document stockpile locations to facilitate subsequent reclamation. Pursuant to Rule 1002.c., Operator shall protect all stockpiled soils from degradation due to contamination, compaction and, to the extent practicable, from wind and water erosion during drilling and production operations. Operator shall implement best management practices to prevent weed establishment and to maintain soil microbial activity. On October 22, 2015, Operator submitted an application for Oil and Gas Location Assessment to amend the existing 20F Pad (ID 414880, “Location”) (Document No. 400913858, “Form 2A”). Location is an expansion of an existing location and is within a sensitive wildlife habitat area. COGCC approved Operator’s Form 2A with the inclusion of construction best management practices (“BMP”) stating “Stockpiles for topsoil and excess cut material will be located in work areas surrounded by a BMP.” On September 5, 2017, Operator submitted a Form 42, Notice of Construction of Location, to notify COGCC of the September 9, 2017, intended start of construction of the Location (Document No. 401395038). Upon inspection on May 1, 2018, COGCC Staff observed that topsoil from new construction could not be identified (Field Inspection Report No. 666801621, including photographs). Based on observations made and photographs taken in the field during this inspection, COGCC Staff determined that excavation operations had been undertaken and either topsoil had not been salvaged and stockpiled, or stockpiles had degraded to the point that they no longer existed. Operator failed to stockpile topsoil from excavation operations at the Location, violating Rule 1002.b.(2). Operator failed to protect stockpiled soils from degradation, violating Form 2A required BMPs and § 34-60-121.(1)(a), C.R.S., and Rule 1002.c. Enforcement Action: Corrective Action Description: Operator will select one of two options for corrective action. The first (“Option 1”) is to provide a topsoil plan; the second (“Option 2”) is to provide financial assurance (a bond) for the topsoil replacement during interim and final reclamation. Option 1 will include the following: A. Submitting and obtaining COGCC approval for a detailed topsoil plan, and B. Assessment of cubic yards of soil not salvaged and of soil quality. As part of the topsoil plan, Operator shall provide soil sample results from the reference topsoil and a separate soil sample results for the topsoil replacement soil. Locations of soiI samples on a reference area and the topsoil replacement soil location shall be included on a figure depicting the soil sample locations overlaid on aerial imagery. The topsoil plan shall include agronomic soil properties of the existing reference topsoil and the soil properties of the replacement topsoil. Operator shall conduct soil analysis including, at a minimum, the following: pH Saturated Paste, electrical conductivity (ec), organic matter, nitrate nitrogen, phosphorus, potassium, zinc, iron, manganese, copper, and lime and texture estimates, percent calcium carbonate equivalency, SAR, and fertilizer or amendment suggestions for the soil to be added during reclamation. If topsoil will be brought in from a completely different location, then it shall be from a source that does not have weed infestation of any kind. The replacement soil should be of the same quality to the reference topsoil. Additionally, the topsoil plan shall include when the topsoil will be imported and how it will be stockpiled and protected on the location, or a nearby stockpile location, including weed management. At a minimum, the topsoil shall be stockpiled on or near the location no later than two months after the approval of the topsoil plan. Option 2 will include the submittal of a Sundry Notice (“Form 4”) with specific information, similar to the information required for Notice to Operators (NTO) Interim Reclamation Procedures for Delayed Operations variance. The complete Option 2 shall include the following: A. Assessment of the quantity of topsoil not salvaged per the rules; B. Assessment of all 3rd party cost associated with topsoil replacement including transportation and topsoil spreading; C. Financial assurance submitted by Operator once the bonding amount is reviewed and approved by the Reclamation staff. Bond shall not be returned until site has passed final reclamation per rule 1004. Operator shall submit the topsoil plan or bond Form 4 by the corrective action date. Final Resolution Comment:

Final Resolution Comment:

Document No.: 401755554 Rule: 324A Rule Description: Pollution Alleged Violation Description: Pursuant to Rule 324A.a., Caerus Piceance LLC (“Operator”) shall take precautions to prevent significant adverse environmental impacts to air, water, soil, or biological resources to the extent necessary to protect public health, safety and welfare, including the environment and wildlife resources, taking into consideration cost-effectiveness and technical feasibility to prevent the unauthorized discharge or disposal of oil, gas, E&P waste, chemical substances, or other oilfield waste. Pursuant to Rule 324A.b., in the conduct of any oil or gas operation, Operator shall not perform any act or practice which constitutes a violation of water quality standards or classifications established by the Water Quality Control Commission (“WQCC”) for waters of the state. On September 13, 2017, Operator submitted an Initial Spill Report (Form 19-I No. 401401658) to COGCC, reporting discovery on September 12, 2017, of a produced water spill (ID No. 452145, “Spill”) in the K35 CDP Pipeline (“Line”) in Garfield County. Operator reported that the Line failed a scheduled pressure test and spilled an unknown volume greater than 5 barrels of condensate and/or produced water. Operator submitted subsequent documents indicating the spill was first discovered on September 11, 2017. (Form 27-S Attachment No. 401446392, submitted by Operator; Excavation and Assessment Summary, Document No. 2227833, submitted by LT Environmental at Operator’s request). In subsequent reporting, Operator submitted a third-party failure analysis which determined the cause of the failure in the Line to be due to Microbially Induced Corrosion (“MIC”) causing pitting and breach, with the amount of microorganisms indicating “high priority for treatment and routine monitoring.” (Failure Analysis, Form 4 Attachment No. 401445993). Operator also submitted the analysis results of groundwater and soil samples taken between October 17 and 19, 2017, which showed exceedances of WQCC and COGCC Table 910-1 standards for Benzene, Toluene, Ethylbenzene, and Xylene (collectively “BTEX”), Total Petroleum Hydrocarbons (“TPH”), and Sodium Adsorption Ratio (“SAR”); and indicated that Liquid Phase Hydrocarbons (“LPH”) were documented in groundwater monitoring wells as far away as 2000 ft downgradient from the Spill point. (Supplemental Site Investigation/Remediation Workplan No. 401446345, with Attachment No. 401446392). Collectively, these documented impacts constitute significant adverse environmental impacts. Operator failed to take reasonable precautions, such as implementing an effective corrosion prevention program before pressurizing the Line, to prevent the contamination of groundwater by the unauthorized discharge of E&P waste, violating Rule 324A.a. Operator spilled E&P waste into state groundwater, which resulted in a violation of WQCC water quality standards, thereby violating Rule 324A.b. Enforcement Action: Corrective Action Description: Operator shall immediately: - Begin active remediation of the LPH from the ground water surface and the subsurface soil deposits above the groundwater surface. Within 15 days of NOAV issuance: - Operator shall conduct a systematic evaluation of the entire Produced Water Transfer System network of pipelines to determine the likelihood of recurrence of Spills/Releases. The evaluation should include a thorough process review and assessment of management of change procedures and address Operator’s ability to identify and stop pipeline leaks in a timely and effective manner. This evaluation must be commenced within 15 days of issuance of this NOAV, and progress reported in the monthly remediation progress reports described in the “By the corrective action due date” section below. By the corrective action due date, Operator shall: - Submit Supplemental Site Investigation and Remediation Reports detailing active ongoing remediation and future remediation plans or options for LPH, dissolved phase hydrocarbon, and soil impacts. - Submit a Supplemental Site Investigation and Remediation Workplan delineating the extent of the impacted area, including LPH, dissolved phase hydrocarbons, and soil impacts. - Submit Supplemental Form 27 progress reports on a monthly basis, due the first business day of each month, with the first report due within 30 days of issuance of this NOAV, until REM #10527 has been closed in accordance with the 900 Series Rules or this requirement has been rescinded in writing by the Director. In addition to monthly progress reports of active remediation efforts, Operator shall resume current schedule of submitting groundwater sampling results on a quarterly basis. Within 6 months of NOAV issuance - Based on the evaluation conducted, Operator shall develop a written plan and schedule to bring its flowlines into compliance with the rules and standards of the February 2018 flowline rulemaking no later than October 2019, and that addresses how similar Spills/Releases will be avoided in the future. The plan must include system engineering, corrosion prevention program, pressure testing of this segment of flowline, management, and training actions, as necessary. This plan must be completed within 6 months. Final Resolution Comment:

On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state (COGCC Spill/Release ID 451556). Caerus determined the cause of the spill to be an inadequate fuse between two pieces of the polyethylene pipeline. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423) Caerus failed to take the reasonable precaution of correctly butt-fusing the polyethylene pipeline, in violation of Rule 1102.a.(1). Enforcement Action: Corrective Action Description: Caerus will submit to COGCC a written plan detailing operational and engineering procedures to prevent recurrence. The plan shall include correct butt-fusing procedures for polyethylene pipe, Quality Assurance & Quality Control (QA/QC) procedures for pipeline installation, pressure testing requirements and procedures for temporary pipelines, personnel and contractor training requirements, and management procedures and responsibilities. Final Resolution Comment:

Document No.: 401541465 Rule: 324A.a Rule Description: General Environmental Protection Alleged Violation Description: Pursuant to Rule 324A.a., Caerus Piceance LLC (“Caerus”), shall take precautions to prevent significant adverse environmental impacts to air, water, soil, or biological resources to the extent necessary to protect public health, safety and welfare, including the environment and wildlife resources, taking into consideration cost-effectiveness and technical feasibility to prevent the unauthorized discharge or disposal of oil, gas, E&P waste, chemical substances, or other oilfield waste. On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state (COGCC Spill/Release ID 451556). Caerus determined the cause of the spill to be an inadequate fuse between two pieces of the polyethylene pipeline (Spill/Release Supplemental Report, Document No. 401372750). On August 7, 2017, COGCC Staff conducted an environmental field inspection and observed the E&P waste flow path, the replaced pipeline segment, and the ponds into which the E&P Waste fluids discharged (Inspection Document No. 689100030). Caerus estimated a volume of 500 bbls of an Exploration and Production (“E&P”) Waste mixture of fresh and produced water flowed downhill following the pipeline path and entered a dry natural drainage. Farther down the drainage, the E&P Waste directly impacted surface water and two ponds in a series of four ponds fed by stormwater and by a nearby spring. Caerus placed oil absorbent booms and pads along the spill path; and pumped the water from the uppermost pond, waited for the pond to refill partially (from the spring), and pumped the pond dry again. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423) Caerus failed to take the reasonable precaution of correctly butt-fusing the polyethylene pipeline, in violation of Rule 324A.a. This inadequate fuse spilled E&P waste such that Caerus had to remove two pond volumes of surface water in their effort to remediate the environmental impact of the spill. Enforcement Action: Corrective Action Description: Caerus will submit to COGCC a written plan detailing operational and engineering procedures to prevent recurrence. The plan shall include correct butt-fusing procedures for polyethylene pipe, Quality Assurance & Quality Control (QA/QC) procedures for pipeline installation, pressure testing requirements and procedures for temporary pipelines, personnel and contractor training requirements, and management procedures and responsibilities.

(Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423) Caerus’s unsatisfactory fusing of the polyethylene pipeline was a failure to securely fasten and maintain this pipeline in good mechanical condition, in violation of Rule 605.d. Enforcement Action: Corrective Action Description: Caerus will submit to COGCC a written plan detailing operational and engineering procedures to prevent recurrence. The plan shall include correct butt-fusing procedures for polyethylene pipe, Quality Assurance & Quality Control (QA/QC) procedures for pipeline installation, pressure testing requirements and procedures for temporary pipelines, personnel and contractor training requirements, and management procedures and responsibilities.

Document No.: 401541465 Rule: 324A.b Rule Description: Water Quality Alleged Violation Description: Pursuant to Rule 324A.b., in the conduct of any oil or gas operation, Caerus Piceance LLC (“Caerus”), shall not perform any act or practice which constitutes a violation of water quality standards or classifications established by the Water Quality Control Commission for waters of the state. On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state, including both groundwater and surface water (COGCC Spill/Release ID 451556). On August 7, 2017, COGCC Staff conducted an environmental field inspection and observed the E&P waste flow path, the replaced pipeline segment, and the ponds into which the E&P Waste fluids discharged (Inspection Document No. 689100030). Caerus estimated a volume of 500 bbls of an Exploration and Production (“E&P”) Waste mixture of fresh and produced water flowed downhill following the pipeline path and entered a dry natural drainage. Farther down the drainage, the E&P Waste directly impacted surface water and two ponds in a series of four ponds fed by stormwater and by a nearby spring. Caerus sampled the soil along the spill path and surface water from the ponds and downstream. This sampling indicated exceedances of Table 910-1 and Water Quality Control Commission Regulation #37 Stream Classification and Water Quality Standard, Lower Colorado River. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423; Sampling Analytical Results, Document Nos. 401372986 and 401375431). Caerus spilled E&P waste into waters of the state, which resulted in a violation of WQCC water quality standards, thereby violating Rule 324A.b. Enforcement Action: Corrective Action Description: Caerus shall submit to COGCC a Form 27 – Site Investigation and Remediation Workplan containing and implementing plans for the following: 1. Semi-annual sampling along the path of the spill from the spill site to uppermost pond until soil EC levels comply with Table 910-1. 2. Quarterly surface water sampling from pond inlets and outlets until chloride and TDS levels comply with WQCC water quality standards and Table 910-1 in consideration of background concentrations established at Pond 3 Inlet on 7/29/1, at least through December 2018. 3. A sensitive area determination according to Rule 901.e. Final Resolution Comment:

Document No.: 401541465 Rule: 907.a Rule Description: General E&P Waste management Requirements Alleged Violation Description: Pursuant to Rule 907.a., Caerus Piceance LLC (“Caerus”) shall (1) ensure that E&P waste is properly stored, handled, transported, treated, recycled, or disposed to prevent threatened or actual significant adverse environmental impacts to air, water, soil or biological resources or to the extent necessary to ensure compliance with the concentration levels in Table 910-1, with consideration to WQCC groundwater standards and classifications; and (2) conduct E&P waste management activities, and construct and operate facilities, to protect the waters of the state from significant adverse environmental impacts from E&P waste, except as permitted by applicable laws and regulations. On July 29, 2017, while pumping a mixture of freshwater and produced water from a water staging area at the 697-26A pad location (COGCC Location ID 416157) to the C23-697 pad location (COGCC Location ID 335512), Caerus personnel noticed a break in the polyethylene surface pipeline that caused a spill into waters of the state (COGCC Spill/Release ID 451556). On August 7, 2017, COGCC Staff conducted an environmental field inspection and observed the E&P waste flow path, the replaced pipeline segment, and the ponds into which the E&P Waste fluids discharged (Inspection Document No. 689100030). Caerus estimated a volume of 500 bbls of an Exploration and Production (“E&P”) Waste mixture of fresh and produced water flowed downhill following the pipeline path and entered a dry natural drainage. Farther down the drainage, the E&P Waste directly impacted surface water and two ponds in a series of four ponds fed by stormwater and by a nearby spring. Caerus placed oil absorbent booms and pads along the spill path; and pumped the water from the uppermost pond, waited for the pond to refill partially (from the spring), and pumped the pond dry again. Caerus also sampled the soil along the spill path and surface water from the ponds and downstream. This sampling indicated exceedances of Table 910-1 and Water Quality Control Commission Regulation #37 Stream Classification and Water Quality Standard, Lower Colorado River. (Spill/Release Initial Report, Document No. 401358483; Spill/Release Supplemental Reports, Document Nos. 401367875, 401372750, and 401375423; Sampling Analytical Results, Document Nos. 401372986 and 401375431). Caerus failed to manage E&P waste in a manner to protect waters of the state such that Caerus had to pump the pond dry twice in their effort to remediate the environmental impact of the spill, and the spill resulted in a violation of WQCC water quality standards and Table 910-1 concentration levels, thereby violating Rule 907.a. Enforcement Action: Corrective Action Description: Caerus shall submit to COGCC a Form 27 – Site Investigation and Remediation Workplan containing and implementing plans for the following: 1. Semi-annual sampling along the path of the spill from the spill site to uppermost pond until soil EC levels comply with Table 910-1. 2. Quarterly surface water sampling from pond inlets and outlets until chloride and TDS levels comply with WQCC water quality standards and Table 910-1 in consideration of background concentrations established at Pond 3 Inlet on 7/29/1, at least through December 2018. 3.

Document No.: 401939600 Rule: 303.b. Rule Description: Form 2A, Oil and Gas Location Assessment Alleged Violation Description: Pursuant to Rule 303.b.(1)A., unless exempted under Rule 303.b.(2), Caerus Piceance LLC (“Operator”) shall complete and obtain COGCC approval of an Oil and Gas Location Assessment (“Form 2A”), for any surface disturbance for an oil and gas location at a previously undisturbed site. Pursuant to Rule 303.g., if construction operations are not commenced on an approved Oil and Gas Location within 3 years after the date of approval, then the approval shall become null and void. The Director shall not approve extensions to Form 2As. Operator received approval on July 15, 2013, of its Oil and Gas Location Assessment (Document No. 400431667) (“Form 2A”) for a surface disturbance at Cuttings Area for UWF H04 596 (ID No. 433573, “Location”), such approval to expire on July 14, 2016. Operator did not file a new Form 2A application to replace the expired Form 2A approval. On March 29, 2018, COGCC Staff inspected the Location and observed that the Cuttings Management Area appeared to have been completed and was receiving drill cuttings from the adjacent UWF H04 596 (Location ID No. 335907). (Field Inspection Report No. 680102819, “March FIR”). Responding to corrective actions required by the March FIR, Operator submitted a Sundry Notice on April 25, 2018, in which it stated that “construction began on December 20, 2017 and ended on January 2, 2018. Cuttings started accumulating on March 20, 2018.” (Form 4 No. 401620659). As of February 7, 2019, Operator has not submitted a current Form 2A or obtained current COGCC approval for the surface disturbance at the Location. Operator disturbed the surface at a previously undisturbed site to construct a new oil and gas location without current Form 2A approval, violating Rule 303.b.(1)A. Enforcement Action: Corrective Action Description: Within 14 days of NOAV issuance, Operator shall submit to COGCC for approval a complete Form 2A for the Location, and shall not continue construction or any further surface disturbance, in any area, without an approved Form 2A for such disturbance.

Final Resolution Comment:

Document No.: 401939600 Rule: 34-60-121(1) CRS-b Rule Description: Statutory Violation - Permit Violation Alleged Violation Description: Pursuant to COGCC Conditions of Approval (“COA”) in Caerus Piceance LLC (“Operator”)’s Oil and Gas Location Assessment (“Form 2A”), (Document No. 400431667), for the Cuttings Area for UWF H04 596 (ID No. 433573, “Location”), Operator is required to prevent accumulation of liquids greater than de minimis amounts by keeping the moisture content of any drill cuttings placed in a cuttings trench, area, or pile as low as practicable. On March 29, 2018, COGCC Staff inspected the Location and observed sediment and materials migration from the top of the pad (flat staging/dump point) to the southwest corner of the pad, and required Operator to take corrective action to contact the relevant COGCC Environmental Protection Specialist (“EPS”) by April 6, 2018, to address the migration. (Field Inspection Report No. 680102819, including Photo Nos. 5 and 6). On April 4, 2018, COGCC conducted a follow up inspection and documented further evidence of migration of the dumped cuttings and drilling mud and aggravating conditions including that the pad was constructed on a slope (approximately 20 degrees) and the surface of the pad had been ripped and the exposed rock was weathered and fractured, which may increase the possibility of fluids infiltrating into the bedrock. COGCC Staff observed that the cuttings/drilling mud mix retained greater than de minimis liquids. COGCC Staff required Operator to take corrective actions to address the moisture content and potential subsurface infiltration and prevent reoccurrence of the unacceptable conditions. On April 12, 2018, Operator emailed the COGCC EPS to describe work taken to complete some of the required corrective actions (Email Document No. 2496339, “Email”), and on April 25, 2018, Operator submitted a Sundry Notice with further details about the corrective actions taken (Document No. 401620659, “Form 4”). On November 20, 2018, COGCC Staff inspected the Location and observed fluid accumulations on cuttings stockpiles, and cuttings migration and evidence of fluid migration leading from multiple stockpiles to the lowest point of the pad. COGCC Staff noted that the observed fluid accumulations and evidence of migration indicated that the associated corrective action had not been adequately addressed by the actions described in Operator’s Email and Form 4 responses. (Field Inspection Report No. 681701120, including attached Photo Nos. 3-8 and Additional CA Document No. 681701129) Operator failed to keep the moisture content of any drill cuttings placed in a cuttings trench, area, or pile as low as practicable, and allowed the accumulation of liquids greater than de minimis amounts, violating Operator’s Form 2A COA and § 34-60-121.(1)(a), C.R.S. Enforcement Action: Corrective Action Description: Operator shall immediately remove and properly dispose of fluid accumulations at the Location. In its Rule 522.d.(2) Answer, due within 28 days of the Operator’s receipt of the NOAV, Operator shall provide to COGCC the following: 1) Operator shall review the efficacy of the desiccating amendment in adequately reducing the moisture content of the fluids deposited at the Location, and shall develop and submit a plan (subject to modification by the COGCC Environmental group) to supplement or replace this approach such that the following will be consistently achieved at the Location: a) Prevent accumulation of liquids greater than de minimis amounts, b) Prevent migration of cuttings, drilling mud, and fluids across or off the Location, and c) Prevent infiltration of fluids into the subsurface; 2) Operator shall review the efficacy of the crossripping in best managing stormwater and fluid migration at the Location, and the risks such ripping may present in facilitating fluid infiltration into the subsurface. Operator shall review Rule 1002.f. and implement appropriate stormwater BMPs at cuttings stockpiles at the Location to prevent future migration of cuttings and fluids. Operator shall submit photographic evidence of the implementation at the Location of stormwater BMPs it has determined to be appropriate. (If the Location will no longer be receiving cuttings/drilling fluids as of the date of NOAV issuance, Operator may instead demonstrate that the stormwater BMPs it has implemented are appropriate to the current state and use of the Location); and 3) Operator shall review the efficacy of the stated 14 day frequency of stormwater inspections in timely identifying and addressing fluid accumulation and preventing fluid migration/infiltration. Operator shall propose an appropriate frequency for conducting its future stormwater inspections and shall submit justification of the adequacy of the proposed frequency. Final Resolution Comment:

Document No.: 401733750 Rule: 1002.f Rule Description: Stormwater Management Alleged Violation Description: Pursuant to Rule Caerus Piceance LLC (“Operator”) shall implement and maintain Best Management Practices (“BMPs”) at all oil and gas locations to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation; and shall maintain BMPs until the facility is abandoned and final reclamation is achieved pursuant to Rule 1004. Operator shall employ BMPs, as necessary to comply with this rule, at all oil and gas locations, including, but not limited to, well pads, soil stockpiles, access roads, tank batteries, compressor stations, and pipeline rights of way. BMPs shall be selected based on site-specific conditions, such as slope, vegetation cover, and proximity to water bodies, and may include maintaining in-place some or all of the BMPs installed during the construction phase of the facility. Best Management Practices indicate that Operator shall implement such protection upon commencement of construction. On October 22, 2015, Operator submitted an application for Oil and Gas Location Assessment to amend the existing 20F Pad (ID 414880, “Location”) (Document No. 400913858, “Form 2A”). Location is an expansion of an existing location and is within a sensitive wildlife habitat area. COGCC approved Operator’s Form 2A on December 18, 2018, with a condition of approval (“COA”) including the following requirements: “The Location is in an area of moderate to high run-on/run-off potential; therefore standard stormwater BMPs must be implemented prior to, during, and after construction; as well as during drilling, completion, and production operations; at this Location to ensure compliance with COGCC requirements and to prevent any stormwater run-on and /or stormwater run-off”; “The access road will be maintained as to not allow any sediment to migrate from the access road to nearby surface water or any drainages leading to surface water.”; and “Run-on protection and run-off controls will be installed prior to the beginning of construction activities, as practicable, with consideration given to worker safety, wildlife, and site access.” On September 5, 2017, Operator submitted a Form 42, Notice of Construction of Location, to notify COGCC of the September 9, 2017, intended start of construction of the 20F Pad (ID 414880, “Location”) (Document No. 401395038). In response to a complaint of property damage due to inadequate stormwater controls at the Location received May 1, 2018, (Document No. 200445816), COGCC Staff inspected the Location that day and observed that sufficient BMPs had not been installed; those BMPs in place were ineffective and had not been maintained or repaired in accordance with good engineering practices. COGCC staff observed erosion and sediment migration throughout the location including the fill and cut slopes. The erosion included movement of sediment, gravel, and cobbles that moved down the unstabilized slopes. Slash and other debris had been pushed off location. Stormwater BMPs appeared to consist of straw wattles at limited locations at the base of the fill slope. The wattles were not installed properly, nor were they used in a correct situation, and have not been maintained. Sediment deposition including silt, sand, cobbles, and boulders are moving off the fill slope and onto previously undisturbed surface areas that should not have been disturbed. Fill slopes were not stabilized. Structures that appear to have been intended to be stormwater BMPs have been overwhelmed by sloughing of sediment, gravel, and cobbles from the fill slopes. These structure Enforcement Action: Corrective Action Description: Operator shall install or repair BMPs as indicated in Field Inspection Report No. 666801621; including, but not limited to: stormwater wattles, retention ponds, ditches, berms; and as needed to allow and protect access throughout the length of the access road as it intersects with potential runoff or erosion from the Location. By the corrective action due date, Operator shall submit an eForm 4 Sundry Notice which documents Operator’s actions to install and maintain adequate stormwater controls throughout the Location, and includes photograph evidence of corrective action completion.

On October 22, 2015, Operator submitted an application for Oil and Gas Location Assessment to amend the existing 20F Pad (ID 414880, “Location”) (Document No. 400913858, “Form 2A”). Location is an expansion of an existing location and is within a sensitive wildlife habitat area. COGCC approved Operator’s Form 2A with the inclusion of construction best management practices (“BMP”) stating “Stockpiles for topsoil and excess cut material will be located in work areas surrounded by a BMP.” On September 5, 2017, Operator submitted a Form 42, Notice of Construction of Location, to notify COGCC of the September 9, 2017, intended start of construction of the Location (Document No. 401395038). Upon inspection on May 1, 2018, COGCC Staff observed that topsoil from new construction could not be identified (Field Inspection Report No. 666801621, including photographs). Based on observations made and photographs taken in the field during this inspection, COGCC Staff determined that excavation operations had been undertaken and either topsoil had not been salvaged and stockpiled, or stockpiles had degraded to the point that they no longer existed. Operator failed to stockpile topsoil from excavation operations at the Location, violating Rule 1002.b.(2). Operator failed to protect stockpiled soils from degradation, violating Form 2A required BMPs and § 34-60-121.(1)(a), C.R.S., and Rule 1002.c. Enforcement Action: Corrective Action Description: Operator will select one of two options for corrective action. The first (“Option 1”) is to provide a topsoil plan; the second (“Option 2”) is to provide financial assurance (a bond) for the topsoil replacement during interim and final reclamation. Option 1 will include the following: A. Submitting and obtaining COGCC approval for a detailed topsoil plan, and B. Assessment of cubic yards of soil not salvaged and of soil quality. As part of the topsoil plan, Operator shall provide soil sample results from the reference topsoil and a separate soil sample results for the topsoil replacement soil. Locations of soiI samples on a reference area and the topsoil replacement soil location shall be included on a figure depicting the soil sample locations overlaid on aerial imagery. The topsoil plan shall include agronomic soil properties of the existing reference topsoil and the soil properties of the replacement topsoil. Operator shall conduct soil analysis including, at a minimum, the following: pH Saturated Paste, electrical conductivity (ec), organic matter, nitrate nitrogen, phosphorus, potassium, zinc, iron, manganese, copper, and lime and texture estimates, percent calcium carbonate equivalency, SAR, and fertilizer or amendment suggestions for the soil to be added during reclamation. If topsoil will be brought in from a completely different location, then it shall be from a source that does not have weed infestation of any kind. The replacement soil should be of the same quality to the reference topsoil. Additionally, the topsoil plan shall include when the topsoil will be imported and how it will be stockpiled and protected on the location, or a nearby stockpile location, including weed management. At a minimum, the topsoil shall be stockpiled on or near the location no later than two months after the approval of the topsoil plan. Option 2 will include the submittal of a Sundry Notice (“Form 4”) with specific information, similar to the information required for Notice to Operators (NTO) Interim Reclamation Procedures for Delayed Operations variance. The complete Option 2 shall include the following: A. Assessment of the quantity of topsoil not salvaged per the rules; B. Assessment of all 3rd party cost associated with topsoil replacement including transportation and topsoil spreading; C. Financial assurance submitted by Operator once the bonding amount is reviewed and approved by the Reclamation staff. Bond shall not be returned until site has passed final reclamation per rule 1004. Operator shall submit the topsoil plan or bond Form 4 by the corrective action date. Final Resolution Comment:

Operator reported a spill of unknown volume greater than 5 barrels of condensate and/or produced water from its K35 CDP Pipeline (“Line”) in Garfield County, discovered on September 11 or 12, 2017. (Spill ID No. 452145, “Spill”) (Form 19-I No. 401401658). On October 31, 2017, Operator submitted a third-party failure analysis which determined the cause of the failure in the Line to be due to Microbially Induced Corrosion (“MIC”) causing pitting and breach, with the amount of microorganisms indicating “high priority for treatment and routine monitoring.” The third-party analysis report described the corrosion as “pitting on multiple spots...on the interior of the pipe and one hole that breached the pipe from the inside out” and “large, jagged pits with terraced sides, … [representing] areas where sessile bacteria have deposited...as they destroy the surface of the pipe.” (Failure Analysis, Form 4 Attachment No. 401445993). Operator failed to maintain the Line in good mechanical condition, violating Rule 605.d. Enforcement Action: Corrective Action Description: Operator shall immediately: - Begin active remediation of the LPH from the ground water surface and the subsurface soil deposits above the groundwater surface. Within 15 days of NOAV issuance: - Operator shall conduct a systematic evaluation of the entire Produced Water Transfer System network of pipelines to determine the likelihood of recurrence of Spills/Releases. The evaluation should include a thorough process review and assessment of management of change procedures and address Operator’s ability to identify and stop pipeline leaks in a timely and effective manner. This evaluation must be commenced within 15 days of issuance of this NOAV, and progress reported in the monthly remediation progress reports described in the “By the corrective action due date” section below. By the corrective action due date, Operator shall: - Submit Supplemental Site Investigation and Remediation Reports detailing active ongoing remediation and future remediation plans or options for LPH, dissolved phase hydrocarbon, and soil impacts. - Submit a Supplemental Site Investigation and Remediation Workplan delineating the extent of the impacted area, including LPH, dissolved phase hydrocarbons, and soil impacts. - Submit Supplemental Form 27 progress reports on a monthly basis, due the first business day of each month, with the first report due within 30 days of issuance of this NOAV, until REM #10527 has been closed in accordance with the 900 Series Rules or this requirement has been rescinded in writing by the Director. In addition to monthly progress reports of active remediation efforts, Operator shall resume current schedule of submitting groundwater sampling results on a quarterly basis. Within 6 months of NOAV issuance - Based on the evaluation conducted, Operator shall develop a written plan and schedule to bring its flowlines into compliance with the rules and standards of the February 2018 flowline rulemaking no later than October 2019, and that addresses how similar Spills/Releases will be avoided in the future. The plan must include system engineering, corrosion prevention program, pressure testing of this segment of flowline, management, and training actions, as necessary. This plan must be completed within 6 months. Final Resolution Comment:

Document No.: 401755554 Rule: 324A Rule Description: Pollution Alleged Violation Description: Pursuant to Rule 324A.a., Caerus Piceance LLC (“Operator”) shall take precautions to prevent significant adverse environmental impacts to air, water, soil, or biological resources to the extent necessary to protect public health, safety and welfare, including the environment and wildlife resources, taking into consideration cost-effectiveness and technical feasibility to prevent the unauthorized discharge or disposal of oil, gas, E&P waste, chemical substances, or other oilfield waste. Pursuant to Rule 324A.b., in the conduct of any oil or gas operation, Operator shall not perform any act or practice which constitutes a violation of water quality standards or classifications established by the Water Quality Control Commission (“WQCC”) for waters of the state. On September 13, 2017, Operator submitted an Initial Spill Report (Form 19-I No. 401401658) to COGCC, reporting discovery on September 12, 2017, of a produced water spill (ID No. 452145, “Spill”) in the K35 CDP Pipeline (“Line”) in Garfield County. Operator reported that the Line failed a scheduled pressure test and spilled an unknown volume greater than 5 barrels of condensate and/or produced water. Operator submitted subsequent documents indicating the spill was first discovered on September 11, 2017. (Form 27-S Attachment No. 401446392, submitted by Operator; Excavation and Assessment Summary, Document No. 2227833, submitted by LT Environmental at Operator’s request). In subsequent reporting, Operator submitted a third-party failure analysis which determined the cause of the failure in the Line to be due to Microbially Induced Corrosion (“MIC”) causing pitting and breach, with the amount of microorganisms indicating “high priority for treatment and routine monitoring.” (Failure Analysis, Form 4 Attachment No. 401445993). Operator also submitted the analysis results of groundwater and soil samples taken between October 17 and 19, 2017, which showed exceedances of WQCC and COGCC Table 910-1 standards for Benzene, Toluene, Ethylbenzene, and Xylene (collectively “BTEX”), Total Petroleum Hydrocarbons (“TPH”), and Sodium Adsorption Ratio (“SAR”); and indicated that Liquid Phase Hydrocarbons (“LPH”) were documented in groundwater monitoring wells as far away as 2000 ft downgradient from the Spill point. (Supplemental Site Investigation/Remediation Workplan No. 401446345, with Attachment No. 401446392). Collectively, these documented impacts constitute significant adverse environmental impacts. Operator failed to take reasonable precautions, such as implementing an effective corrosion prevention program before pressurizing the Line, to prevent the contamination of groundwater by the unauthorized discharge of E&P waste, violating Rule 324A.a. Operator spilled E&P waste into state groundwater, which resulted in a violation of WQCC water quality standards, thereby violating Rule 324A.b. Enforcement Action: Corrective Action Description: Operator shall immediately: - Begin active remediation of the LPH from the ground water surface and the subsurface soil deposits above the groundwater surface. Within 15 days of NOAV issuance: - Operator shall conduct a systematic evaluation of the entire Produced Water Transfer System network of pipelines to determine the likelihood of recurrence of Spills/Releases.
