Intermittent odors present at wellhead and various spots on location. Consistent odors present within soundwall enclosure whre there is a large muffler and exhaust. BP claims source of odors is likely an adjacent well (Craig 2E-DK)and there was a recent incident of inhibitor/H2S scavenger being burned in the dehydrator at restart of the well after shut-in. This well is also scheduled for a new "separator level controller" to mitigate low level odors that BP admitted were still on the location on 4/24. No answer from BP as to why "Prosafe 4x4" rental safety equipment at SU 33-10, 24-3 wellhead. Future nuisance from odors from any BP wells or equipment in this area to nearby residences should warrant an NOAV.

  • Date Received: April 10, 2015 Document No.: 200429211 NOTIFICATION LA PLATA Operator: Wpx Energy Production Llc Facility: BONDAD 33-10 Description: I went to my 40 acre property with a road contractor the first week of March. When we arrived, there was a drilling rig, 6-7 vehicle, s huge black tank, many workers at the WPX site 33-8-23. They were set up where we access the property. They advised they were doing s P&A,maned would be gone in spa week. It was very muddy and the two track road obvious on aerial plats and our survey was indistinguishable. I had no notice at anytime that anyone would be on my property. I don't have a surface agreement. Things drug on and April 3 I met Mark Lepich with WPX at property. He said they would level and reseed the road. There was gravel there. While I was waiting at property for Lepich, a big flat bed arrives, unloads a backhoe and 2 men. I asked them what they were doing now, but neither spoke English. Thus was uncomfortable for me at my property, again, without notice We have been delayed over a month, and have now missed a deadline to build to old road standards. New standards will be $10,000+ additional. I think WPX has been condescending to me. They said the cogcc would only allow them to reseed. Resolution: Clarification was needed as to whether the ranch road that crosses through the northern portion of the well pad should remain after final reclamation. COGCC determined that the road has been in place for as long as we can determine from aerial imagery (at least 1993). An inspection was submitted to operator detailing the road determination and the need for the road to remain. Surface owner expressed satisfaction and gratitude for the resolution and efforts.

Laposta Canyon Road is the legal access to the canyon for 75 years Now2 gates have been locked off by what appears to be oil/gas locks,blocking use of such bridge, Conoco has an agreement to maintain this road. They installed a low water crossing for their heavy equipment to get in out, which they do not keep cleared, But indicate we should use it. 1] Landowners have spend up to 5+ hours clearing this site to pass out of canyon 2] The blockages are caused by bad weather, bad design & a oil company installed pipeline crossing creek. This pipeline ditch was back filled, but the rain came along, washed fill into creek, and changed course of creek, causing damage to bridge banks No clean up by company for 5 years we have asked for. 3] The depth of the fill has been 5 foot plus, landowners took over 5 hours to dig thru debris, with gas employees watching. Landowners have repeatedly had to clear this area to get out. There is no way out .The bridge & this portion of road has been dropped off their maintenance; [which is NOT to road standards] all together. We just had an occasion where one of the canyon residents needed hospice care, family had to get large 4 wheel drive to get thru this low water crossing, because the nurses could not take a normal car thru 14 + inches of mud & rock. Many landowners use this bridge, it is not great, but it is what we have; now they seem to be trying to block us from using the legal road. This located pass first bridge next to their concrete low water crossing. Today there is 12 inches of water in low water crossing from rain, bad maintenance because the dirt was not cleared so water could flow away. This needs to be opened now to have some way out or in by emergence equipment [ fire, ambulance] thank you 2 gates have been locked off by what appears to be oil/gas locks, blocking use of such bridge, Conoco has an agreement to maintain this Resolution: Meeting scheduled with primary operator about low water crossing and issues identified during investigation of previous and still open complaint doc# 200416174.

Seems to die down during the day. Has been going on for about a week or two. I believe its the well located on Eugene Harper's property, Lat/Long 37.186769 -107.544667. See comments above. Noise can be heard at our location later in the evening throughout the night. My neighbor to the south of me about 1/4 to 1/2 mile also hears it. COGCC SW Field Inspector Joe Maclaren spoke with complaintant (6/30/15 @ 9:51am) and identified the gas well location/ source of noise. A field inspection was conducted (same day 6/30)at this location. The source of the noise was identified and determined to be a gas compressor on the SE corner well pad. The complaintant was subsequently updated and informed that a COGCC sound study would follow and the results would be communicated at the completion. (via follow up phone call 6/30/15 @ 2:15 pm). Resolution: Conducted 15 minute noise survey with 3M SoundPro DL meter ser. no. BGN010014 with a factory calibration date of 4.28.15 begining at 11:10 AM at 141' from compressor and 4' above ground, clear skies, light wind (1-3 mph) from southwest. Average reading was 65.2 db(a) which calculates to 57.3 db(a) at 350'. Distance calculation used due to topography (arroyo) between edge of pad and complainants residence. Noise from equipment needs to be reduced to below 50 db(a) per Rule 802.a as soon as possible and no longer than the presumed 30 day corrective action time. Muffler is currently on side of compressor that faces direction of complainants residence. WAV file of noise data and graph are available upon request. Action Required on FIR Doc #667700660 reads as follows: Reduce noise levels to below 50 db(a) when measured at 350' toward complainant residence for 24 hour equipment as soon as possible but no later than corrective action date of 8/1/15.

I have contacted them numerous times and they have refused to comment and chose to have their senior counsel in Houston address my concern, Ms. Elysia Linson. She had me speak with an industrial hygienist of BP's, refused to comment on the safety or potential emissions from the well, and told me to direct future communications with her through an attorney. She also requested and received comprehensive information form me regarding my health and operations but will not even tell me what kind of glycol dehydration process is being used at the well. There is very little smell. After the red trucks showed up I smelled what smelled like pain thinner very intensely, but it passed relatively quickly. My building is intensely ventilated. I move over 4000 CFM through the building constantly. I believe prevailing wind direction, proximity, and topography are preventing adequate dissipation of the well's emissions and BP refuses to comment on or fix the problem. People in the building have reported upset stomachs and headaches. I experience lethargy, severe chest pain to the point of being hospitalized, confusion, and extreme emotional distress because no one has helped me and few people understand that natural gas is odorless. ,Chest pain resulting in multiple hospital visits causing me to vacate the building in fear of adverse health effects. Prevailing wind direction, proximity, and topography is preventing adequate dissipation. There is yellow spray paint and tape all over the glycol dehydrator.

No gas was observed other than intermittent releases from the pneumatic controller. Field inspection supervisor issued an inspection (doc#667700689) with the infrared footage attached and asked operator to confirm that vertical separator and valves were functioning properly and within manufacturers specifications. Operator confirmed this in addition to confirming that the pneumatics were compliant with CDPHE air regulations and that the domestic tap and associated mercaptan system once used on property have been completely disconnected and removed. At request of complainant, staff conducted an additional infrared survey on 9/25/15 focusing on areas around location and above pipeline and around and in metal building to look for any possible leaks from buried lines, no gas was detected during this survey and a satisfactory inspection was issues (doc#667700697).

It appears that the equipment which is leaking belongs to Williams (based on signs and markings) but other companies also operate at this location. Based on their failure to correct previous problems with spills and chemicals on the well pad, I have not contacted them on this particular problem. A leak or drip from a compressor or other device was falling on a concrete footer and then washing onto the ground. For a while, there was a small plastic bucket catching some of the leakage, but there was still staining of the concrete and soil even with the bucket. Was noticed some time ago. The bucket disappeared between Thursday, 27 AUG 2015 and Wednesday, 02 SEP 2015 when a crew was on the well pad. But the leakage continues to drop on the concrete and wash off during precipitation. In the bucket there was a shine or film and the liquid when collecting in the bucket had some sediment in it. There was/is an odor and the liquid is a dark brown in color. Other agencies have been contacted on past problems on this site, and we are in contact with US EPA and CDPHE regarding other issues, and are considering notifying them of this problem, as well. Resolution: Issued FIR doc #674602274 and 667700699 to ConocPhillips and #667700703 to Catamount requiring clean up of de minimus releases identified by complainant at dehydrator and pumping unit as sonn as possible and no later than 10/14/15. Operators are also required to fix source of releases and prevent re-occurrence. These releases are housekeeping issues at this early stage and not reportable spills. There is no imminent threat to surface or groundwater from amounts observed during inspections. The releases did not appear to be rapidly worsening.

The inspector determined that there was de minimis staining originating from dehydrator and pumping units and issued FIRs with action required (FIR # 667700703, 674602274, and 667700699). The complaint was closed out. The complainant has filed an additional complaint relating to the facility requesting soil sampling. The new complaint states: "Little Fishes, LLC is the owner of the property where the above facility is located. Mr. Malouf is one of its principals. Nathan Barton, also listed as a complainant, is the Malouffs / Little Fishes’ environmental engineer. The Malouffs / Little Fishes property surrounds the well site and extends east from the well pad across County Road 213 and to the Animas River. The Malouffs / Little Fishes operate a wildlife habitat on the east side of County Road 213, which includes a series of ponds. The wildlife habitat is down gradient from the well pad, its western border is within 300 feet of the well pad and it is hydrologically connected to the well pad. The above referenced Complaint relates to a steady leak from a dehydrator unit operated by Williams Field Services, but which services Catamount according to Doc. No. 667700699. The leak has been observed by Mr. Malouff since early June 2015, and was apparently uncontrolled for an unknown period of time. The scope of any soil contamination resulting from the leak has been masked by grading on the site. At some point, a bucket was placed by someone to catch the leakage. The bucket was removed on or about August 27, 2015, but the dehydrator continues to leak as of the date of this letter. Nothing has been done to our knowledge to evaluate and characterize the extent of resulting soil contamination on and off the pad or to repair the leak.

  • Date Received: March 8, 2016 Document No.: 200439149 SOIL CONTAMINATION LA PLATA Operator: Catamount Energy Partners Llc Facility: ANIMAS-M34N10W Description: Location of concern is reported as: Facility or Site Number 333603, in La Plata County, operated by Catamount, Williams, and Conoco Phillips. Well pad on property of Little Fishes LLC. Complainant states: Property, ground and surface water, and soils on the Little Fishes LLC property, including the wildlife habitat and waters of the United States continue to be at risk from activities at this location, because the operating companies have failed to adequately plan and implement actions, including spill prevention and control, storm water management (best management practices), and reclamation of areas disturbed and outside their legal leased area. It has now been more than two years since various notices of corrective actions required were issued, according to COGCC records. Yet the operators still have not implemented an effective storm water management plan and other plans to prevent or control runoff of storm water carrying contaminants from their activities, and have not demonstrated to an acceptable recognized standard the results of their clean-up and other work on site to comply with federal, state, tribal, and local laws and rules. The three companies have continued to operate in conditions and with materials not properly protected so that discharges and therefore contamination to water and soils off the well pad can continue with any storm event. They have not complied with the provisions of Section 906 regarding reporting and coordination on releases that have occurred and which have been documented both by on-site inspection and by laboratory testing. The efforts to get the companies (Catamount, Williams, and Conoco Phillips) to take action would take too long to detail here, as would conversations with other agencies and organizations. The attorney for Little Fishes LLC has the records of these contacts with the companies and their agents and representatives. This information has been provided multiple times to COGCC personnel. Resolution: Complainants concerns were addressed through Remediation Project numbers 9436, 9630, and 9601. Inspections (detailing corrective actions issued by COGCC and actions by the operators) are documented in FIR numbers 674900874, 674900903, 674900994, 674901059, 674901084, 680600229, 680600315, and 680601058. Complaint closure letter detailing COGCC and operator actions is attached to the complaint record.

The well has been inactive for a long time. It was installed by Hathaway Operators. Last night he was in the pasture and noticed that the valve that was formerly on the well was missing and water was leaking out of the well. Complainant does not know how long the leak has been ongoing or how the valve was damaged (possibly by cattle). Areas that have been impacted by the water have no vegetation growth. The water was pooling in a low spot around the well and also traveling down to and into an irrigation ditch. Area impacted is less than 1/8 acre. Complainant does not know how long the leak has been ongoing. Resolution: On 3/23/16 SW Regional Engineer and SW EPS conducted a field inspection of the Hathaway Flint #1. The well head was releasing fluids. The release was stopped by COGCC staff. The well will be placed into the PRAW program.

Occasionally it gets extremely loud, to the point where I can't be outside or I lose my mind. I have to have a fan on inside at night or I hear that constant popping sound. I have a tenant above my garage, and he can't sleep at night with the noise. BP has responded at least 3 different times over the past year when the noise is out of control, and they make it tolerable. However, they Band-Aid the problem and it continues to keep happening. Recently, the well has been running 24-7. A few weeks ago I complained about the noise, and per Miles at BP, a field supervisor went to inspect the well. She said the noise level was within compliance and again they "Band-Aided" the problem. The problem, and my biggest complaint, is this old cheap rusted exhaust system on the well. It constantly breaks and falls apart and becomes extremely loud. They go re-connect the same old rusted leaking pipe and cheap muffler system. This involves wrapping wire and tinfoil around it, which I'm surprised could be within compliance. I have offered several times to buy a new pipe and muffler myself, but BP doesn't seem interested. I've taken pics and videos of the system and they say as long as it's within "compliance" they won't do anything. I think a lot of my noise problem is seeping from the old rusted exhaust pipe that they continue to use. I know the system could be quiet and tolerable, and would stop breaking down if they just put a new pipe and "acceptable" muffler on the system. I would do if myself if I was allowed to. I'm tired of calling them and having them come out to bandage up the problem, when it could be fixed. This would be a huge relief for myself and my family as well as my tenant. I could lose my rental income because of the noise, and I'm afraid I'll have trouble selling the house because of the well. I think putting a new exhaust system Resolution: Conducted site inspection and sound survey. Inspection document number 685303650. Decibel levels were below allowable limits of A scale. Residence is within 400' of gas powered engine. Issued corrective action to operator to confirm muffler is quite operation or equivalent and is installed and maintained properly.

  • Date Received: March 22, 2018 Document No.: 200445628 PROPERTY DAMAGE LA PLATA Operator: Bp America Production Company Facility: ALVA SHORT B Description: Without my knowledge or consent Crossfire, a subcontractor for BP, has left the well pad and flagged a large area of many acres in my field. According to BP's Land Agent, Gina Doerner, the purpose of this zone (the white flags call it a BP dig zone) is to park equipment for when a pig is run through the pipelines. She has been told that the pad is too tight for the large trucks to turn around. That explanation makes no sense, as there is a large berm (placed to protect my home from well noise) between the pad and that marked area which forces my farm pickup (and these rigs) to make a very sharp turn to gain entry around my fence. BP has been very aggressive about asserting what it sees as its rights and curtailing mine. Not long ago Tom Dugan, BP attorney, decided that tap agreements I had signed with Amoco, BP's predecessor, for concessions they wanted me to make, were invalid; after considerable legal fees, I reluctantly agreed that my tap rights would terminate when the property was conveyed outside my family. I was bullied by a business that could afford legal expenses that I could not. The two gas producers (BP and Williams Field Services) that share that well pad put in One Calls that result in many metal-stemmed flags being placed on my property, but they never remove those flags when they are done. I am concerned that will happen again. Resolution: Complaint outside COGCC jurisdiction due to pin flags installed off pad and off of disturbed area.

  • Date Received: March 23, 2018 Document No.: 200445646 NOISE LA PLATA Operator: Bp America Production Company Facility: MW JOHNSON A Description: My wife and I own the land upon which this well is located. It was placed prior to our purchase 15 years ago, and ten years ago when we built our home (as well as a Home for my in-laws) the well produced without the need for above ground mechanical structures. The background, as briefly as I can summarize it is as follows: 3 phase power was extended, and exists less than 100' from the well equipment. It was installed prior to any mechanical production equipment being placed on the well. Approximately 8 years ago a generator and pump jack were placed. Many phone calls were made to BP to attempt to mitigate noise that was produced by the well equipment with no resolution. As the equipment aged my number and frequency of phone calls increased. The main issue was that with the rpm's down to a level where a 4+ second pump jack cycle was maintained the noise level was acceptable. Unfortunately, several times a week an operator without knowledge of the verbal agreement with BP reps would crank it up and we would get not only the generator sound, but also mechanical noise from the jack itself. More phone calls but the cycle continued for years. I wish to be clear that every contact I have had with anyone regarding this issue has been respectful and aimed at understanding of the impact of the problem and being solution oriented. I have always expressed appreciation for the contribution oil and gas development and production play in our community. I no longer respect BP's position in our community. I, like many, understand the impact of over-regulation on an industry such as this. Unfortunately BP's unwillingness to take any action to be a good neighbor forces me to push for further, stricter regulatory efforts. The profits they have taken while caring so little about the residents here is appalling, and while individuals appear sympathetic no action has ever been taken. BP has said no to sound walls. They have also denied our (and Keke's) request for Hay or Straw bale barriers. The summer before last I met on site with Ke Resolution:
  • Date Received: March 23, 2018 Document No.: 200445644 NOISE LA PLATA Operator: Bp America Production Company Facility: MW JOHNSON A Description: Constant thumping such as steam engine with periods of increasing intensity. The reverberation can be felt across our entire property and the noise level is such that it now can be heard within our home.We have owned this property for 15+ years and have up until now been able to resolve all issues with the well. Within the last year, BP did work that changed the noise level coming off the well. The new system constantly sounds like a steam engine running, it escalates in noise during the evening hours, and is at such a level that it is heard within our home walls and has completely changed the quality of our lives on our own property. I know longer can be outside of my home without this invasive noise and am moved to tears on most days as the drone of noise has created a level of stress that I have worked so hard to eliminate in the property and home we have built with our own hands. Our home sits one of the greatest distances away and we are so profoundly affected. I can only imagine what it is like for our neighbors that sit nearer to this device. I a mortified that this is sitting on our property and we have no control over our own ability to be a good neighbors and maintain these relationships to the highest level of stewardship we would like. While no indications have been received to date, I do believe at some point these individuals are going to attempt to hold us responsible in some manner as they are also feeling they have no recourse in getting this rectified.

  • Date Received: March 23, 2018 Document No.: 200445648 NOISE LA PLATA Operator: Bp America Production Company Facility: MW JOHNSON A Description: I would like to ask for your help in rectifying an engine noise problem originating from the BP American Production Company well site identified as MW Johnson A1, adjacent to my property. Obviously something at this well site has changed , prompting BP American to change to a different type of pumping engine. I understand that BP classifys this well as PRODUCING every day of the month. However, their clutching mechanism activates the jack pump arm for only a brief period, intermittently each day. The jack pump arm is not in motion most of the time. However, the pump engine drones on relentlessly, 24/7. The noise is most obnoxious on days with no wind. It is worse at nighttime and it is unrelenting on winter days and nights! The pumping engine was changed this past summer. It is a type that produces an loud exhaust noise emanating as a low frequency, pulse pounding, throbbing cycle. The previous engine equipment produced a lesser obtrusive noise which could be described as a continuous humming sound. My residence is approximately 560 feet west of the well pump engine and on a slightly lower grade. When the sound is at its worse it envelopes our home I can even hear it inside of my residence. Our only relief, is to pray for a slight prevailing wind from the south west to mask the sound and carry it away. Not great for our neighbors that are upwind from the well site. BP does talk to us. They have visited with us to hear our concerns. They conducted a one-time test measurement of the decibel levels. BP never conducted testing in the day or night time stillness and not on still winter days when the sound transmission is enhanced in the denser air. BP has never explained their reason for not installing sound barrier panels or choosing to electrify the pump engine. Translation: BP's concern and resultant actions are a sham. The resultant degradation is the quality of our lives from the noise pollution introduced into our environment and the commensurate negative impact on our property values is very real. Your consider Resolution:

Document No.: 401027413 Rule: 912.b Rule Description: Venting or Flaring Natural Gas - Notice and Prior Approval Required Alleged Violation Description: Pursuant to Rule 912.b., except for gas flared or vented during an upset condition, well maintenance, well stimulation flowback, purging operations, or a productivity test, gas from a well shall be flared or vented only after notice has been given and approval obtained from the Director on a Form 4 - Sundry Notice stating the estimated volume and content of the gas. While investigating an odor complaint (Document #200439222) during a March 17, 2016 inspection of Dye-Hard #1 (API 05-067-05446) (Document #685200082), COGCC staff observed that the well was venting gas from the production casing. The Dye-Hard #1 was unattended at the start of the inspection, but a pumper and Operator’s representative arrived shortly thereafter. COGCC staff observed and documented a gas plume with an Optical Imaging Camera (Document # 685200083) and the company representative that prior approval to vent is a requirement under Rule 912.b.

On December 15, 2016 Operator reported a produced water spill through a Form 19, Initial Spill/Release Report, (Document #401167642) due to a leak from the produced water gathering line in NWNW Sec 4, T34N R6W, La Plata County, Colorado (Spill/Release Point ID #448730). This was reported to Operator on December 13, 2016, by the lease operator. Operator responded to the location the same day and stopped the release. On December 14, 2016, during initial assessment of the release area (Document #674901401), COGCC staff confirmed that the produced water had traveled from the release point into Saul’s Creek, which constitutes waters of the state as defined under COGCC Rules. Soil and water samples were collected on December 13, 2016 (Document #401198632 and Document #401198613). Operator submitted a Form 19, Supplemental Spill/Release Report, on December 28, 2016 (Document #401174201). In Document #401174201, Operator indicated that a section of 6” produced water line that failed had been removed from the location and replaced with a carbon steel replacement and the line was returned to service. Operator also stated that water vacuum trucks were still being used at three locations along Saul’s Creek to recover a mix of melted snow, rain, and residual produced water. A Form 27, Site Investigation and Remediation Work Plan, (REM 10004) was submitted on January 31, 2017 (Document #401198595). Document #401198595 indicated that four of eight soil samples and six of seven surface water samples exceeded Table 910-1 standards.

Document No.: 401343967 Rule: 1004.a Rule Description: Final Reclamation - Well Sites Reclamation Alleged Violation Description: Pursuant to Rule 1004, upon the plugging and abandonment of a well, Western Gas Resources, Inc. (Operator) shall: 1) backfill all pits, mouse and rat holes, and cellars; 2) remove all debris and surface equipment within three (3) months; 3) reclaim well locations, access roads, culverts, and associated facilities; and 4) as applicable, perform restoration and revegetation work at well sites, associated production facilities, and access roads to the same standards established for interim reclamation under Rule 1003. All such reclamation work shall be completed within twelve (12) months on non-crop land after plugging a well or final closure of associated production facilities. All areas being reclaimed shall be kept as free as practicable of all undesirable plant species designated to be noxious weeds. Operator plugged and abandoned the North Alkali Gulch #14-22 well, API 05-067-06178, (Well) at Location #385549 on May 8, 2004 (Document #1162407). During an inspection of Location #385549 on July 17, 2012 (Document #668200030), COGCC staff observed that the location was not reclaimed and a pipeline riser and markers remained at the location. Document #668200030 required the Operator to remove the riser and obtain a Rule 502.b. variance to leave the lease road or remove and reclaim it by October 31, 2012. During an inspection of Location #385549 on September 19, 2012 (Document #668200154), COGCC staff met with Operator representatives to evaluate final reclamation requirements. Document #668200154 required Operator to remove the riser and remove the lease road or apply for a variance by December 31, 2012. During an inspection of Location #385549 on August 11, 2016 (Document #680600884), COGCC staff observed that corrective actions noted in the previous inspections have not been addressed. Approximately 2,000 spotted knapweed, 500 musk thistle, 100 leafy spurge, and 50 yellow toadflax were observed within the project area. Document #680600884 noted that the location has been out of compliance since 2005. This inspection required the Operator to reclaim the well pad, access road, and pit area and remove all oil and gas equipment. Document #680600884 also required the Operator to control weeds and stormwater erosion until the location is revegetated. Weeds were to be controlled by September 23, 2016. Final reclamation activities were required to be conducted by November 1, 2016. In September 2016, the Operator requested an extension to the Corrective Action Date to control weeds via a telephone call to COGCC staff. COGCC staff reviewed the request and approved an extension to the corrective action date to October 21, 2016. On November 4, 2016 (Document #401143540), the Operator submitted a Form 4, Sundry Notice, requesting an extension to conduct reclamation to May 31, 2017. This request was reviewed by COGCC staff and denied because the request was made four days after the corrective action date, the location has been out of compliance since 2005, and that corrective actions from inspections conducted in 2012 were not addressed. During an inspection of Location #385549 on May 25, 2017 (Document #680601637), COGCC staff observed that reclamation was not conducted on the location. Spotted knapweed, musk thistle, and leafy spurge were growing on the location. It is not apparent whether weeds were treated in fall 2016. Document #680601637 required the Operator to reclaim the well pad, access road, and pit area and remove all oil and gas equipment.

Document No.: 401829387 Rule: 324A.b Rule Description: Water Quality Alleged Violation Description: Pursuant to Rule 324A.b., in the conduct of any oil or gas operation, BP America Production Company (“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 for waters of the state. On April 19, 2018, Operator reported a spill (ID No. 454826, “Spill”) from a produced water gathering line that had discharged an unknown volume of fluids that flowed into Dry Creek, a Waters of the State (Initial Spill/Release Report Document No. 401615552). The same day, COGCC Staff conducted an environmental inspection (Field Inspection Report No. 688800079, “FIR”) and documented the flow path of the exploration and production (“E&P”) waste of the Spill, which followed an unnamed dry tributary drainage feature north to Dry Creek. Deposits left by the E&P waste are shown in Photograph Nos. 1, 2, 3, and 5 (FIR Attachment No. 688800080). Operator submitted Reports of Soil and Water Sampling, which documented a third-party investigation of the extent and impact of the Spill (Document No. 401667248, dated May 25, 2018, attached to Form 19-S No. 401667212; and Document No. 401684385, dated June 22, 2018, labeled “Revised”, and attached to Form 27-I No. 401684298; “LTE Report”). Page one of both versions of the LTE Report notes “visual observations of salt staining” as an indicator of the geographic extent of the Spill. Operator discharged E&P waste into waters of the state, which resulted in a violation of WQCC water quality standards in Regulation 31, thereby violating Rule 324A.b. Enforcement Action: Corrective Action Description: Operator shall submit an eForm 27 Site Investigation and Remediation Workplan for the investigation of environmental impacts, and remediation of the impacted area. If initial sampling results exceed Table 910-1, Operator shall provide detailed plans of how the impacts will be addressed in the Initial Form 27, including any proposed treatment, monitoring, frequency, or removal. Operator shall monitor the remediated and reclaimed area for revegetation, weeds, and stormwater erosion monthly at a minimum until the remediated and reclaimed areas meet the final reclamation threshold of Rule 1004.c.

Document No.: 401829387 Rule: 605.d Rule Description: O&G Facilities - Mechanical Conditions Alleged Violation Description: Pursuant to Rule 605.d., BP America Production Company (“Operator”) shall keep all valves, pipes, and fittings securely fastened; inspected at regular intervals; and maintained in good mechanical condition. Operator reported an April 19, 2018, spill (Spill/Release ID 454826, “Spill”) of approximately 12.5 barrels of produced water from a gathering line; and that the flowpath of the Spill flowed into Dry Creek, which is considered Waters of the State (Spill/Release Reports Document Nos. 401615552 and 401667212). In its spill/release reporting, Operator described the cause of the spill to be “fiberglass water transfer line failure due to deflection of pipe during installation” (Id.), later clarifying: “Once the line was exposed, it was determined the leak was a result of a stress induced crack in the body of the 3” fiberglass pipe close to the wall thickness transition from the body of the fiberglass pipe to the thicker threaded joint portion of the pipe. The source of the applied stress is unknown.” (June 21, 2018, email from BP Field Environmental Coordinator to COGCC Staff). Operator’s failure to maintain this equipment in good mechanical condition violated Rule 605.d. Enforcement Action: Corrective Action Description: Operator shall submit a written plan detailing operational and engineering procedures to prevent reoccurrence. Operator shall conduct further root cause analysis as necessary to develop such plan. Operator shall submit a preliminary plan within 10 days, with updates to final plan within 90 days.

Document No.: 401829387 Rule: 907.a Rule Description: General E&P Waste management Requirements Alleged Violation Description: Pursuant to Rule 907.a., BP America Production Company (“Operator”) shall ensure that E&P waste is properly stored, handled, transported, treated, recycled, or disposed to the extent necessary to ensure compliance with the concentration levels in Table 910-1, with consideration to WQCC groundwater standards and classifications. Table 910-1 concentration levels in soil indicate Sodium Adsorption Ratio (“SAR”) less than 12 and pH between 6 and 9. Operator reported an April 19, 2018, spill (Spill/Release ID 454826, “Spill”) of approximately 12.5 barrels of produced water from a gathering line; and that the flowpath of the spill flowed into Dry Creek, which is considered Waters of the State (Spill/Release Reports Document Nos. 401615552 and 401667212). On June 13, 2018, Operator submitted a third-party sample analysis report which noted exceedance of Table 910-1 concentrations in three soil samples taken in the Spill path (Analytical Results Document No. 401667250, attached to Form 19 Subsequent No. 401667212). According to this report, the third-party took three soil samples on April 19, 2018, (including SS-01 and SS-02); and five soil samples on May 4, 2018, (including SS-06). From this report: “Soil sample SS-01 contained a pH value of 9.18 and a sar value of 17, while SS-02 contianed a pH value of 9.49 and a SAR value of 43... [soil sample] SS-06 contained a pH value of 9.19, but did not exceed the COGCC Table 910-1 standard for SAR… The saltwater impact [from the Spill] is evident in the elevated pH and SAR values observed in soil samples collected within the release footprint.” COGCC Field Inspection Report 688800079 further documents the flow path from the point of origin to the entry into Dry Creek. Operator failed to properly manage their E&P Waste to the extent necessary to ensure compliance with the concentration levels in Table 910-1, violating Rule 907.a. Enforcement Action: Corrective Action Description: Operator shall submit an eForm 27 Site Investigation and Remediation Workplan for the investigation of environmental impacts, and remediation of the impacted area. If initial sampling results exceed Table 910-1, Operator shall provide detailed plans of how the impacts will be addressed in the Initial Form 27, including any proposed treatment, monitoring, frequency, or removal. Operator shall monitor the remediated and reclaimed area for revegetation, weeds, and stormwater erosion monthly at a minimum until the remediated and reclaimed areas meet the final reclamation threshold of Rule 1004.c.

Document #680601637 required the Operator to reclaim the well pad, access road, and pit area and remove all oil and gas equipment. This inspection also required the Operator to control weeds and stormwater erosion until the loca Enforcement Action: Corrective Action Description: Operator shall reclaim the access road, well pad, and pit area. The riser shall be removed and the weeds shall be controlled. Final Resolution Comment:

Document No.: 401829387 Rule: 605.d Rule Description: O&G Facilities - Mechanical Conditions Alleged Violation Description: Pursuant to Rule 605.d., BP America Production Company (“Operator”) shall keep all valves, pipes, and fittings securely fastened; inspected at regular intervals; and maintained in good mechanical condition. Operator reported an April 19, 2018, spill (Spill/Release ID 454826, “Spill”) of approximately 12.5 barrels of produced water from a gathering line; and that the flowpath of the Spill flowed into Dry Creek, which is considered Waters of the State (Spill/Release Reports Document Nos. 401615552 and 401667212). In its spill/release reporting, Operator described the cause of the spill to be “fiberglass water transfer line failure due to deflection of pipe during installation” (Id.), later clarifying: “Once the line was exposed, it was determined the leak was a result of a stress induced crack in the body of the 3” fiberglass pipe close to the wall thickness transition from the body of the fiberglass pipe to the thicker threaded joint portion of the pipe. The source of the applied stress is unknown.” (June 21, 2018, email from BP Field Environmental Coordinator to COGCC Staff). Operator’s failure to maintain this equipment in good mechanical condition violated Rule 605.d. Enforcement Action: Corrective Action Description: Operator shall submit a written plan detailing operational and engineering procedures to prevent reoccurrence. Operator shall conduct further root cause analysis as necessary to develop such plan. Operator shall submit a preliminary plan within 10 days, with updates to final plan within 90 days.

Document No.: 401829387 Rule: 907.a Rule Description: General E&P Waste management Requirements Alleged Violation Description: Pursuant to Rule 907.a., BP America Production Company (“Operator”) shall ensure that E&P waste is properly stored, handled, transported, treated, recycled, or disposed to the extent necessary to ensure compliance with the concentration levels in Table 910-1, with consideration to WQCC groundwater standards and classifications. Table 910-1 concentration levels in soil indicate Sodium Adsorption Ratio (“SAR”) less than 12 and pH between 6 and 9. Operator reported an April 19, 2018, spill (Spill/Release ID 454826, “Spill”) of approximately 12.5 barrels of produced water from a gathering line; and that the flowpath of the spill flowed into Dry Creek, which is considered Waters of the State (Spill/Release Reports Document Nos. 401615552 and 401667212). On June 13, 2018, Operator submitted a third-party sample analysis report which noted exceedance of Table 910-1 concentrations in three soil samples taken in the Spill path (Analytical Results Document No. 401667250, attached to Form 19 Subsequent No. 401667212). According to this report, the third-party took three soil samples on April 19, 2018, (including SS-01 and SS-02); and five soil samples on May 4, 2018, (including SS-06). From this report: “Soil sample SS-01 contained a pH value of 9.18 and a sar value of 17, while SS-02 contianed a pH value of 9.49 and a SAR value of 43... [soil sample] SS-06 contained a pH value of 9.19, but did not exceed the COGCC Table 910-1 standard for SAR… The saltwater impact [from the Spill] is evident in the elevated pH and SAR values observed in soil samples collected within the release footprint.” COGCC Field Inspection Report 688800079 further documents the flow path from the point of origin to the entry into Dry Creek. Operator failed to properly manage their E&P Waste to the extent necessary to ensure compliance with the concentration levels in Table 910-1, violating Rule 907.a. Enforcement Action: Corrective Action Description: Operator shall submit an eForm 27 Site Investigation and Remediation Workplan for the investigation of environmental impacts, and remediation of the impacted area. If initial sampling results exceed Table 910-1, Operator shall provide detailed plans of how the impacts will be addressed in the Initial Form 27, including any proposed treatment, monitoring, frequency, or removal. Operator shall monitor the remediated and reclaimed area for revegetation, weeds, and stormwater erosion monthly at a minimum until the remediated and reclaimed areas meet the final reclamation threshold of Rule 1004.c.

Document No.: 401948613 Rule: 1102 Rule Description: Operations, Maintenance, and Repair Alleged Violation Description: Pursuant to Rule 1102.i.; BP America Production Company (“BP America”) must take reasonable precautions to prevent failures and leakage, and minimize corrosion of flowlines and crude oil transfer lines. On November 4, 2018, a surface owner notified BP America that a produced water gathering line failed and discharged an unknown volume of fluids that flowed into the Citizens Animas Ditch, considered to be Waters of the State (Form 19, Initial Spill/Release Report No. 401825843). The spill (Spill/Release ID 458834) was discovered by an adjacent landowner as a surface expression of produced water on a hillside, causing an erosional channel leading downhill to the Citizens Animas Ditch. On November 4, 2018, BP America isolated the pipeline and stopped the release. On November 5, 2018, COGCC Staff conducted an environmental inspection and observed where the fluids had day-lighted, adjacent to a pipeline right of way, approximately 350 feet west of the Citizens Animas Ditch (Field Inspection Report No. 688800333). COGCC Staff again inspected the site of the release on November 9, 2018 (Field Inspection Report No.690100899). During this inspection, COGCC Staff observed that BP America had excavated approximately 80 feet of pipeline, and that two failures were identified where the pipeline was in an “overbent” condition on top of sandbag supports(Id., see also Inspection Photos No. 690100905). BP America filed Form 19, Supplemental Spill/Release Report No. 401832958 on November 15, 2018. In this report, BP America stated that the released fluid contained produced water, formational paraffin inhibitor, and lubricating oil (Id.). BP America stated further that an oily sheen and spotty residue were observed over an area approximately two miles downstream of the release point (Id.). Based on inspections conducted by COGCC Staff, it is evident that BP America should have taken additional precautions to prevent the observed failure of this pipeline. For example, additional sandbags could have been used to better support the pipeline during the installation, or a non-compressive bedding material, such as sand or squeegee could have been used as a continuous bedding material. BP America therefore violated Rule 1102.i.1. Enforcement Action: Corrective Action Description: BP America shall submit a written plan detailing operational and engineering procedures to prevent reoccurrence, which shall address both produced water transfer line integrity issues along with the possibility of reconfiguring the produced water transfer system and produced water management/injection well system to reduce the risks to Waters of the State. Plan should include the possibility of adding additional injection wells. Final Resolution Comment:

Document No.: 401948613 Rule: 324A.b Rule Description: Water Quality Alleged Violation Description: Pursuant to Rule 324A.b.; BP America Production Company (“BP America”), in the conduct of any oil or gas operation shall not perform any act or practice which shall constitute a violation of water quality standards or classifications established by the Water Quality Control Commission for waters of the state, or any point of compliance established by the Director pursuant to Rule 324D. The Director may establish one or more points of compliance for any event of pollution, which shall be complied with by all parties determined to be a responsible party for such pollution. On November 4, 2018, a surface owner notified BP America that a produced water gathering line failed and discharged an unknown volume of fluids that flowed into the Citizens Animas Ditch, considered to be Waters of the State (Form 19, Initial Spill/Release Report No. 401825843).

On November 4, 2018, BP America isolated the pipeline and stopped the release. On November 5, 2018, COGCC Staff conducted an environmental inspection and observed where the fluids had day-lighted, adjacent to a pipeline right of way, approximately 350 feet west of the Citizens Animas Ditch (Field Inspection Report No. 688800333). The E&P waste flow path followed a drainage feature east to the irrigation ditch. Visual impacts were reportedly observed approximately two miles downstream. E&P waste impacted private property near High Flume Canyon and ultimately flowed into the Animas River. The produced water entering the Citizens Animas Ditch caused a sheen on the water and caused the ditch company to shut off flow, impacting up- and downstream users of the water. COGCC Staff again inspected the site of the release on November 9, 2018 (Field Inspection Report No.690100899). During this inspection, COGCC Staff observed that BP America had excavated approximately 80 feet of pipeline, and that two failures were identified where the pipeline was in an “overbent” condition, supported by sandbags (Id.). BP America filed Form 19, Supplemental Spill/Release Report No. 401832958 on November 15, 2018. In this report, BP America stated that the released fluid contained produced water, formational paraffin inhibitor, and lubricating oil (Id.). BP America stated further that an oily sheen and spotty residue were observed over an area approximately two miles downstream of the release point (Id.). Pursuant to Colorado Water Quality Control Commission Rule 31.11(1)(a), Basic Standards Applicable to Surface Waters of the State, state surface waters shall be free from substances attributable to human-caused point source or nonpoint source discharge in amounts, concentrations, or combinations which are harmful to the beneficial uses or toxic to humans, animals, plants, or aquatic life; or cause a film on the surface or produce a deposit on shorelines. As noted above, the release from BP America’s pipeline caused an oily sheen and spotty residue to be observed on waters of the state as part of an impact area approximately two miles downstream of the release point. BP America therefore violated Rule 324A.b. Enforcement Action: Corrective Action Description: BP shall submit an eForm 27 Site Investigation and Remediation Workplan for the investigation of environmental impacts, and remediation of the impacted area. Final Resolution Comment:

Document No.: 401948613 Rule: 324A.a Rule Description: General Environmental Protection Alleged Violation Description: Pursuant to Rule 324A.a.; BP America Production Company (“BP America”) 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 of oil, gas, or E&P waste. On November 4, 2018, a surface owner notified BP America that a produced water gathering line failed and discharged an unknown volume of fluids that flowed into the Citizens Animas Ditch, considered to be Waters of the State (Form 19, Initial Spill/Release Report No. 401825843).

BP America stated further that an oily sheen and spotty residue were observed over an area approximately two miles downstream of the release point (Id.). Based on inspections conducted by COGCC Staff, it is evident that BP America should have taken additional precautions to prevent the observed failure of this pipeline. Alternative installation practices such as sand or squeegee bedding to better support the pipeline during the installation could have been used, which may have prevented this type of failure. The release that resulted impacted an irrigation ditch for a distance of approximately two miles and ultimately resulted in released material reaching the Animas River. BP America therefore violated 324A.a. Enforcement Action: Corrective Action Description: BP America shall submit an eForm 27 Site Investigation and Remediation Workplan for the investigation of environmental impacts, and remediation of the impacted area to Table 910-1 concentration levels. BP America shall provide a detailed map of the land surface and surface waters impacted by the spill. The map shall include aerial imagery, overlain with topography, and show pipeline failure points, soil and water sample locations, boom deployment locations, remedial excavations, property boundaries, and surface waters--including the interconnectedness of Citizens Animas Ditch, ornamental ponds, High Flume Canyon, the Animas River, and any other surface water bodies affected or potentially affected by the spill. BP America shall utilize production records to verify the date of pipeline failure and generate an estimate of the total volume of produced water and other E&P Wastes spilled.

Document No.: 401781508 Rule: 326.b Rule Description: Shut-in Wells Alleged Violation Description: Pursuant to Rule 326.b., BEEMAN OIL & GAS LLC ("Operator") is required to perform a Mechanical Integrity Test ("MIT") on Shut-in ("SI") wells within two (2) years of the initial shut-in date and then at five (5) year intervals after an initial successful MIT. COGCC Rules do not permit placing a well back on production to fulfill, or in lieu of, the requirements to conduct an MIT. COGCC Staff had reason to believe Operator had committed one or more violations of COGCC Rules, and issued Warning Letter No. 401588898 to Operator on March 28, 2018 , requiring Operator to conduct MIT or plug and abandon delinquent wells by June 30, 2018 . On July 24, 2018 , COGCC Staff conducted an audit (“Audit”) of Operator's records for the well(s) in the attached table ("Well"). The Audit included reviewing records such as Operator's Form 7 Monthly Reports of Operations and Field Inspection Reports filed by COGCC Staff after inspecting the Well to determine the dates the Well was SI, and the COGCC database to determine whether Operator reported MIT(s) for the Well. Through this Audit, COGCC Staff determined that at least one Well in the attached table was overdue for performance of an MIT on a SI well. Operator failed to conduct timely MIT(s) for at least one SI Well, violating Rule 326.b. Enforcement Action: Corrective Action Description: In its Rule 522.d.(2) Answer, due within 28 days of the Operator’s receipt of the NOAV, Operator shall provide the following to COGCC:   - Operator shall perform an audit of its Mechanical Integrity Testing and MIT reporting for all its wells in Colorado. Operator shall submit a detailed report to COGCC which shows the following information for each of its wells which has been in SI or TA status for at least one month starting 24 months prior to July 24, 2018 .
