Environmental Checklist and City of Pleasanton–10x Genomics Project <br />Environmental Evaluation Initial Study/Mitigated Negative Declaration <br /> <br /> <br />78 FirstCarbon Solutions <br />Https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480024/ISMND/wp/21480024 10x Genomics Project Full Screencheck ISMND.docx <br />generation rates used in estimating mobile-source emissions were consistent with those <br />presented in the traffic volume data provided in the TIA (Appendix J). <br />2. Indirect Electricity: These emissions refer to those generated by off-site power plants to <br />supply electricity required for the proposed project. The proposed project would be served <br />with electricity by PG&E. The CO2 intensity factors in the operational runs were adjusted to <br />match the most recent data available for PG&E.54 The energy intensity factors for electricity <br />and natural gas consumption for the proposed project were derived from the existing 10x <br />Genomics facility. See the Utility Calculations sheet in Appendix A for more information. <br />3. Water Transport: These emissions refer to those generated by the electricity required to <br />transport and treat the water to be used on the project site. Biogenic GHG emissions <br />generated from water transport emission sources are presented but not utilized in this <br />analysis, consistent with the BAAQMD’s 2017 CEQA Air Quality Guidelines.55 <br />4. Waste: These emissions refer to the GHG emissions produced by decomposing waste <br />generated by the proposed project. Biogenic GHG emissions generated from waste emission <br />sources are presented but not utilized in this analysis, consistent with the BAAQMD’s 2017 <br />CEQA Air Quality Guidelines.56 <br />5. Stationary Source: No stationary sources are proposed as part of the proposed project. <br /> <br />Appendix A provides the full assumptions and detailed modeling results. Table 14 shows the land- <br />use operational GHG emissions that would be generated by the proposed project. The proposed <br />project's net long-term operations would generate approximately 3,989 MT CO2e per year starting in <br />2022. The estimated net operational emissions for the proposed project were compared with the <br />BAAQMD threshold of 4.6 MT CO2e per service population per year to determine significance when <br />the proposed project first becomes fully operational in the year 2022. The estimated annual net <br />land-use GHG emissions generated by the proposed project were also modeled for operational year <br />2030. The results of the proposed project’s estimated 2030 operational emissions are compared <br />with the adjusted threshold of 2.6 MT CO2e per service population per year. <br />Table 14: Operational Land Use-Related Greenhouse Gas Emissions <br />Emission Source <br />Year 2022 Total Emissions <br />(MT CO2e per year) <br />Year 2030 Total Emissions <br />(MT CO2e per year) <br />Area 0 0 <br />Energy 1,257 1,109 <br />Mobile (Vehicles) 3,382 2,571 <br />Waste 67 67 <br />Water 206 196 <br /> <br />54 Bay Area Air Quality Management District (BAAQMD). 2017.
