The DSU associated with this pad is Order No. 407-2359 & 535-939. Due to siting restrictions, Enerplus is limited on the area available to develop this location. In accordance with rule 1003.b. Interim reclamation of areas no long in use, Enerplus is maximizing the use of the working pad space and considers the limited working area to be deems reasonably necessary for production operations of this site. Operator will ensure the new oil and gas operations align with the spirit of the new regulations of protecting public health, safety, welfare, the environment and wildlife resources set by SB 19-181. The location does not meet any of the Director's Objective Criteria. 402442946 402442946 FORM 2A SUBMITTED 402442946.pdf 402442946 402447675 NRCS MAP UNIT DESC NRCS _Olney_fine_sandy_loam_3_to_5_percent_slopes-.pdf 89591 402442946 402447676 HYDROLOGY MAP Calgary Streets Pad - Hydrology Map.pdf 460552 402442946 402447687 LOCATION PICTURES Calgary Streets Pad - Location Pictures.pdf 753328 402442946 402447694 ACCESS ROAD MAP Calgary Streets Pad - Access Road Map Topo A - B.pdf 1421812 402442946 402447768 WASTE MANAGEMENT PLAN Waste Management Plan.pdf 37721 402442946 402447804 MULTI-WELL PLAN Calgary Streets Pad - Multi-Well Plan.pdf 548074 402442946 402456115 LOCATION DRAWING Calgary Streets Pad - Location Drawing.pdf 1187020 402442946 402461384 CONST.

Areas not required foron-going production operations or not required for subsequent drilling operations to be commenced within twelve months shall be reclaimed per COGCC Interim Reclamation requirements. false 79e2c7f3-bc41-4e2c-adc2-4dd7d2ef60fb 402442946 9 Emissions mitigation Associated Gas Flaring BMP. Following the last stage of separation associated gas will flow through a liquid knockout drum to remove entrained liquid phases. Following the liquid knockout drum, associated gas will flow to a smokeless combustion device capable of a 98% control efficiency. The combustion device will be equipped with a continuous pilot gas flame and an auto-ignitor. Operator will comply with all applicable Colorado Air Pollution Control Division requirements to ensure adequate design and operation of the control device is maintained. false 5e35863c-679a-44bb-84aa-6f810e2a7257 402442946 7 Construction Visual Impacts: Equipment, regardless of construction date, which are observable from any public highway shall be painted with uniform, non-contrasting, non-reflective color tones (similar to the Munsell Soil Color Coding System), and with colors matched to, but slightly darker than, the surrounding landscape. false ec178e47-b622-482e-b542-afce8695d20b 402442946 5 Material Handling and Spill Prevention Annual flowline testing will also occur according to COGCC Rule 1104. Inspection and record retention of flowline testing will be in accordance per COGCC regulation. All records will be made available to the COGCC upon request. false ebfe84f1-7a3b-426b-a9a5-b75f41adaa23 402442946 2 General Housekeeping All trash, debris, scrap or discarded material connected with the operations of the property shall be removed from the premises and disposed of in a legal manner. false c2b6d26c-c3ca-4e46-9ac3-bc40c43b8964 402442946 1 Traffic control Operator shall ensure that at the time of construction that all leasehold roads shall be constructed to accommodate local emergency vehicle access requirements and shall be maintained in a reasonable condition. Operator worked with the Weld County Public Works Department to develop a road maintenance agreement and specifc haul routes. false baa300b8-5f59-4609-8374-becbec126e0c 402442946 4 Material Handling and Spill Prevention The wells will be equipped with remote shut-in capabilities prior to commencing production. Remote capabilities include the ability to shut-in the well via a SCADA computer system for gathering, monitoring, and analyzing data in real time. Operator will also have remote monitoring and shut down capabilities including automatic shutdown pressure devices installed on process vessels. All produced fluids are routed onsite via subsurface pipelines to separators and then to the oil and produced water storage tanks at this tank battery. false 38c2f502-a59e-494b-bc5f-e5421ec6935b 402442946 3 Storm Water/Erosion Control Implement and maintain BMPs to control stormwater runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation. Location will comply with applicable Colorado stormwater permitting requirements and associated stormwater management plan (SWMP). Operator utilizes a ditch and berm around the perimeter of the pad to contain sediment and will install sediment traps when adequate slopes allow. At the conclusion of construction, disturbed areas not required for ongoing operations and the topsoil spoil pile will be seeded with an appropriate seed mix. Inspections will occur per CDPHE stormwater regulatory requirements and any evidence of stormwater erosion will be repaired. Culverts will be installed along the lease road and maintained clear of sediment where appropriate. false bc660fa7-124d-494d-85f9-f293d47400e5 402442946 8 Construction Operator certifies that the MLVTs used during completion operations shall only hold fresh water and will be designed and implemented consistent with the COGCC June 13, 2014 Policy on the Use of Modular Large Volume Tanks in Colorado. false 12dec1d3-20db-4d9d-b1ac-f6c801406579 402442946 11 Odor mitigation Operator will use D822 as the base fluid which is a distillate. The characteristics of D822 allow for benefits stemming from lower BTEX levels and lower odor levels when compared to traditional diesel oil-based mud. If odor complaints are received and it is determined that they are caused by the invert drilling fluid, other mitigation steps will be reviewed which may involve the use of chemical additives to mitigate odor impacts. When planning a location, operator will take special consideration to the orientation of the drilling rig to the residential units to minimize the odor impacts. Operator will inspect the site for sources of Odor within 24 hours of a complaint and implement additional odor controls when necessary. false 1b6f7f3c-928a-4305-bd5c-05d4dbefff72 402442946 6 Dust control Operator shall employ practices for control of fugitive dust caused by their operations. Such practices shall include the use of speed restrictions, regular road maintenance, restriction of construction activity during high-wind days, watering of lease roads and pad during construction, and silica dust controls when handling sand used in hydraulic fracturing operations. Additional management practices such as road surfacing, wind breaks and barriers may be used. false 53ba5610-9f08-47ee-8bc4-fdaf6f8e5acf 402442946 10 Emissions mitigation Light sources during all phases of operations will be directed downwards and away from occupied structures. false 402442946 Enerplus Resources (USA)
