There have been no new buildings constructed and no changes to the surrounding land use or mineral lease description. The SHL of the remaining wells have been respaced using existing SHL; cultural distances have been updated. The well site has not yet been constructed. This location is not in a buffer or exception zone, so no notices are required under Rule 305. All previously submitted notices, Surface Use Agreements and letters are also still valid. Since this location is not in a buffer zone, a Waste Management Plan and Facility Layout are not included. Since there are no water features within 1000', a Hydrology Map is not included. Manufacturer of MLVT: Hydrologistics Size and Volume: Up to two (2) 157’ diameter/42,000 BBLs Anticipated time frame on site: 90 days Mallard Exploration consulted with the Briggsdale Fire Protection District and the Weld County Office of Emergency Management (OEM) regarding the proposed facility and emergency response for this location. The site-specific Emergency Action Plan was approved by Briggsdale Fire on May 20, 2019 and the OEM on September 23, 2019. 402377261 402377261 FORM 2A SUBMITTED 402377261.pdf 402377261 402378514 ACCESS ROAD MAP Wigeon Fed Pad 7N60W4 Access Road Map.pdf 1226663 402377261 402378515 LOCATION DRAWING Wigeon Fed Pad 7N60W4 Location Drawing.pdf 811422 402377261 402378516 REFERENCE AREA MAP Wigeon Fed Pad 7N60W4 Reference Area Map.pdf 546808 402377261 402378519 REFERENCE AREA PICTURES Wigeon Fed Pad 7N60W4 Reference Photos.pdf 1431985 402377261 402378520 MULTI-WELL PLAN Wigeon Fed Pad 7N60W4 Multi-Well Plan.pdf 537786 402377261 402378521 NRCS MAP UNIT DESC 44_N_Olney_fine_sandy_loam_0_to_6_percent_slopes--Weld_County_Colorado_Northern_Part.pdf 121234 402377261 402378523 NRCS MAP UNIT DESC 45_N_Olney_fine_sandy_loam_6_to_9_percent_slopes--Weld_County_Colorado_Northern_Part.pdf 121004 402377261 402379167 LOCATION PICTURES Wigeon Fed Pad 7N60W4 Location Photos.pdf 1331604 402377261 402364832 02 Wigeon Fed 33-28-1HN 402377261 402364833 02 Wigeon Fed 33-28-2HN 402377261 402364834 02 Wigeon Fed 33-28-3HN 402377261 402364835 02 Wigeon Fed 33-28-4HN 402377261 402364836 02 Wigeon Fed 33-28-5HN 402377261 402364837 02 Wigeon Fed 33-28-6HN 402377261 402364838 02 Wigeon Fed 33-28-7HN 402377261 402364839 02 Wigeon Fed 33-28-8HN c4e40d96-e5e9-4a5f-ae9a-3a0bc7f04c7c 402377261 2 Storm Water/Erosion Control Implement and maintain BMPs to control storm water runoff in a manner that minimizes erosion, transport of sediment offsite, and site degradation. Gas and water gathering lines will be co-located to minimize potential of erosion associated with construction of any pipeline(s). false 9fa38a72-3515-46bc-8e90-3dd4dddafd12 402377261 8 Material Handling and Spill Prevention If a leak is discovered or suspected, the well will be shut in and the line will be hydrotested. If a leak is determined, the well remains shut in while the leak is located and repaired. Not until the line has passed hydrotesting, will the well be brought back online. false 8d13a3d8-9d22-4033-9197-46bb73f03b23 402377261 5 Material Handling and Spill Prevention Audible, Visual, and Olfactory (AVO) inspections of the facility are conducted daily by the Operator. Any valve or fitting that is found to be ineffective is either repaired immediately or well shut-in procedures are implemented. false 9ad27263-ca62-4cad-b20d-47e2f5a302ae 402377261 7 Material Handling and Spill Prevention The location will utilize a SCADA (remote monitoring) system to monitor facility pressures and flows. Sensors are placed on multiple points throughout the facility and are designed to measure the system for irregularities that would indicate a leak in the system or change in production of oil, water, or gas. The SCADA system is designed with alarms that are triggered by irregularities will activate automatic shut-in of the well and facility. false 118ff322-be77-4953-8c57-79451efaa48e 402377261 11 Interim Reclamation Operator shall be responsible for segregating the topsoil, backfilling, re-compacting any backfill, reseeding, and re-contouring the surface of any disturbed area so as not to interfere with Owner’s operations and shall reclaim such area to be returned to preexisting conditions as best as possible with control of all noxious weeds. false 3949f260-f18d-44c2-952f-a99050eab103 402377261 3 Storm Water/Erosion Control A sediment trap will be constructed to capture any sediment prior to leaving the location. The sediment trap has been sized in accordance with good engineering practices. A temporary diversion, consisting of a cut swale and compacted earthen berm, will be constructed along the pad edge and routed to the sediment trap to prevent offsite migration of sediment/contaminant into the nearby surface water features. If necessary, check dams will be constructed within the swale. false 5c9d57ae-65a9-44c9-bd0f-dbdbff6b490c 402377261 4 Material Handling and Spill Prevention All flowlines are designed/constructed/tested to ASME B31.4 and API 1104 standards. Only materials with Material Test Reports (MTRs) provided by the pipeline supplier are used in the construction of the flowlines. false 1316fcda-6307-43ea-bb66-f3de0baa158b 402377261 10 Construction Operator will install an engineered containment system around the tank battery. The containment system is constructed of a perimeter of metal walls that are post driven into the ground around a flexible geotextile base. All components are then sprayed with a polyurea liner technology. This liner technology maintains impermeability and is puncture resistance under exposure to UV rays, weather extremes, and chemicals commonly encountered in oil and natural gas production, and provides seamless protection. The liner is then topped with pea gravel. Secondary containment will be installed around separators and treaters consisting of metal berm walls. The separators and treaters will be set on top of compacted road base. false c842d337-ac2e-42fc-aa48-8834c53d8171 402377261 9 Construction Operator will have a MLVT Design Package, certified and sealed by a licensed professional engineer, which is on file in their office and available upon request. The site shall be prepared in accordance with the specifications of the design package prior to tank installation; including ensuring that proper compaction requirements have been met. MLVT will be at least 75 feet from a wellhead, fired vessel, heater-treater, or a compressor with a rating of 200 horsepower or more. MLVT will be placed at least 50 feet from a separator, well test unit, or other non-fired equipment. All liner seams will be welded and tested in accordance with applicable ASTM international standards. Operator will be present during initial filling of the MLVT and the contractor will supervise and inspect the MLVT for leaks during filling. Operator will comply with the testing and re-inspection requirements and associated written standard operating procedures (SOP) listed on the design package. Signs will be posted on the MLVT indicating that the contents are freshwater. MLVT will be operated with a minimum of 1 foot of freeboard at all times. Access to MLVT will be limited to operational personnel and authorized regulatory agency personnel. Operator or contractor will conduct daily visual inspections of the exterior wall and surrounding area for integrity deficiencies. Operator will have a contingency plan/emergency response plan associated with MLVT on file at their office. A fabric reinforced liner will be utilized. In the event that a tank breach were to occur, the fabric reinforced liner will prevent a “zippering” failure from occurring. The liner will meet the specifications per the design package. Operator acknowledges and will comply with the Colorado Oil & Gas Conservation Commission Policy on the Use of Modular Large Volume Tanks in Colorado dated June 13, 2014. false e6bd6af2-7a35-400b-a9a4-1ec36738ac17 402377261 6 Material Handling and Spill Prevention Documented Audible, Visual, and Olfactory (AVO) inspections and optical gas imaging surveys are conduced monthly by a third-party specialist. false 65cf5099-ef2e-4f71-9467-87b498870651 402377261 1 General Housekeeping 804. Visual Impacts: All long term facility structures will be painted a color that enables the facilities to blend in with the natural background color of the landscape, as seen from a viewing distance and location typically used by the public. Maintain appearance with garbage clean-up; a trash bin will be located on site to accumulate waste by the personnel drilling the wells. Site will have unused equipment, trash and junk removed immediately. false 402377261 Barracuda Investments LLC
