CONSERVATION GROUPS’ COMMENTS <br />UNCOMPAHGRE FIELD OFFICE RMP AND DEIS <br />45 <br />we generated potential lifecycle greenhouse gas emissions for resultant oil and gas volumes <br />using a peer-reviewed carbon calculator and lifecycle greenhouse gas emissions model <br />developed by EcoShift consulting.129 This model is not novel in its development or <br />methodology. Numerous greenhouse gas calculation tools exist to develop lifecycle analyses, <br />particularly for fossil fuel extraction, operations, transport and end-user emissions.130 <br /> <br />For purposes of this comment letter, we have provided a complete and accurate GHG <br />lifecycle emissions analysis for the potential volume of new leasable parcels of oil and gas for <br />each alternative in the UFO draft RMP:131 <br /> <br />Alternative <br />Oil or Gas <br />(volume <br />units) Volume Tons of CO2e <br />A Oil (MMbbl) 17.479285 6,123,094.60 <br />A Gas (Bcf) 118.734952 8,866,471.01 <br /> <br />14,989,565.61 <br />B Oil (MMbbl) 14.11527 4,944,646.73 <br />B Gas (Bcf) 99.371955 7,404,024.85 <br /> <br />12,348,671.58 <br />B1 Oil (MMbbl) 13.704939 4,801,019.02 <br />B1 Gas (Bcf) 75.311941 5,611,358.53 <br /> <br />10,412,377.55 <br />C Oil (MMbbl) 17.477671 6,122,744.29 <br />C Gas (Bcf) 118.728611 8,846,279.30 <br /> <br />14,969,023.59 <br />D Oil (MMbbl) 17.469117 6,119,591.48 <br />D Gas (Bcf) 117.273097 8,737,795.42 <br /> <br />14,857,386.90 <br /> <br /> <br />David Sinton, Geographic Information Systems Specialist, BLM Uncompahgre Field Office, re: <br />Uncompahgre draft RMP and EIS shapefiles supplemental data (October 7, 2016 2:14 PM MT). <br />Methodology used: Intersect the leasable oil and gas areas for each alternative provided in the <br />Dropbox files and on the planning website for the Uncompahgre field office’s draft RMP and <br />EIS with the model layer from BLM’s Oil and Gas Inventory Model Geodatabase. Then <br />calculate new acreage for each polygon and multiply the "Total Oil Density" and "Total Gas <br />Density" layers by this acreage to create volume data. The resultant maps are attached as <br />Exhibits 79-83. 129 See Mulvaney (attached as Exhibit 23). 130 See Council on Environmental Quality, Revised draft guidance for greenhouse gas emissions <br />and climate change impacts (2014), https://ceq.doe.gov/current_developments/GHG-accounting- <br />tools.html. 131 See supra note 128, Center for Biological Diversity, Maps and volume estimates.
