Pressure testing shall be conducted and the documented results will be retained by the operator for inspection by the Director for a period of one (1) year. Activation of the pipe rams for function testing shall be conducted on a daily basis when practicable. false 1b678203-07e7-416b-b6f7-567eeddbea22 403312983 3 Wildlife - A single aerial drone survey will be conducted covering a 0.6 mile buffer from the edge of the Working Pad Surface after March 10, 2023 in compliance with Colorado Parks and Wildlife Greater Prairie Chicken protocol. - Operator will promptly provide written notification to Colorado Parks and Wildlife and COGCC of the results of the Greater Prairie Chicken aerial drone survey. - Should one or more Lek sites be identified within the survey area, Carbon America will deploy sound mitigation such as hay bales in consultation with Colorado Parks and Wildlife and COGCC prior to spudding the stratigraphic well. false 30647bab-4b13-4461-b19b-7cd7c6ddd2e3 403312983 7 Construction Topsoil will be segregated during construction to be redistributed during interim reclamation. Topsoil will be segregated in non-impervious areas adjacent to the well pad. Proper site preparation would be ensured by spreading of stored and salvaged topsoil or topsoil replacement to an adequate depth and by ripping, tilling, disking, harrowing, and dozer track imprinting where appropriate. false 81968c7c-be34-49b7-b48c-86252ac45d46 403312983 4 Storm Water/Erosion Control Stormwater controls include silt fence, mulch, Curlex erosion control blanket, and filter logs/rolls or straw bales. The sediment barriers will typically be installed at the base of slopes adjacent to ditches, drainage channels, and other excavated material must be placed in such a manner that if a storm event was to occur, the sediment would flow into the excavation. BMPs will be installed on the downslope side of the excavations to contain the sediment within the Project Area. false 758719ae-5ae9-47cc-b930-96a807464970 403312983 13 Final Reclamation If the operator is no longer planning to use the well as a carbon sequestration injection or monitoring well, the well will be plugged and abandoned and the location reclaimed pursuant to COGCC Rules or the operator will transfer the well and location to a subsequent operator pursuant to Rule 218. false 9d90ca9a-7d8a-4d2c-a6a3-a4c61df19819 403312983 11 Interim Reclamation After the topsoil has been returned to these areas and prepared for seeding, a landowner-approved weed-free seed mix would be planted to prevent erosion, preserve soil integrity, and resist weeds. false 1c59f69a-8ecb-4218-9fef-b0af93a16cb1 403312983 5 Material Handling and Spill Prevention Once drilling operations are completed, all debris and waste will be removed from location by the contractor and disposed of properly in commercial waste containers. All excavations unnecessary for operations will be backfilled per industry standards. false 07eff9ed-c759-4917-8fe7-c250889d4dd7 403312983 2 Wildlife • Install avian deterrents on equipment when the equipment is planned to be left inactive for longer periods of time to prevent migratory bird nesting. • Operator will coordinate with the surface owner and CPW to use recommended and approved seed mixes for reclamation. • A pre-construction migratory bird survey will be performed within the approved disturbance area prior to construction activities (if construction is between April 1 to August 31) false 3c5acbee-a572-4a7a-ac3e-cb21ab9bf386 403312983 6 Dust control • Carbon America may utilize freshwater or flocculants for dust suppressant practices. • Speed restrictions on the access road will be utilized to minimize dust. An average speed of 20 miles per hour is currently anticipated to be used for most vehicles. • Construction activities may be limited or deferred on high-wind days to restrict potential fugitive dust. • Topsoil and stockpiled soils will be stabilized through the use of either tackifiers, seeding practices, or erosion control blankets. false 8bcd57eb-1695-4726-9b7e-d0b1dbffca39 403312983 12 Interim Reclamation The location will be inspected for noxious weeds monthly at a minimum. If invasive plants are identified during an inspection, Carbon America will consult with the local weed control agency and weed control measures will be conducted in compliance with the Colorado Noxious Weed Act. false 282f2267-6cc6-46f3-acfb-e4cd87b8f6f4 403312983 10 Drilling/Completion Operations No reserve pit will be utilized. A closed-loop solids control system will be utilized to capture all drilling operational waste. Generated waste will be transported to the nearest facility permitted to accept the waste. false aa084a4d-8939-4012-bbcf-f46907aa7736 403312983 1 Planning Reference area photos will be taken when vegetation is at its peak and submitted via Form 4 sundry before October 31, 2023 due date per COGCC. false 403312983 1ST 12 1 4 9 5 8 43.5 4222 983 4222 0 0 PLANNED J55 false false false 403312983 2ND 8 3 4 7 23/35 5150 1109 5150 0 0 PLANNED L80 false false false 403312983 CONDUCTOR 26 20 65 80 115 80 0 0 PLANNED N/A false false false 403312983 SURF 17 1 2 13 3 8 54.5 700 440 700 0 0 PLANNED J55 false false false 403312983 LAKOTA LKTA 403312983 LYONS LYNS Thread was being aborted.
