Section 5 <br />Construction Emissions <br />GHGs would be emitted by off-road and on-road construction equipment and <br />worker vehicles. Construction emissions for the Proposed Project were <br />calculated using CalEEMod. GHG emissions for each construction activity and <br />the total two year construction effort are shown in Table 24. The total <br />construction GHG emissions, which would occur over a two-year period, would <br />be substantially less than the one-year CEQA and NEPA thresholds, <br />Table 24: Estimate Proposed Project Construction Greenhouse Gas <br />Emissions <br />Activity <br />Unit Emissions <br />(MTCO2e) <br />Number of <br />Activities <br />Total <br />Emissions <br />(VITCO2e) <br />Pipefines, Shared Structures, Heritage Site <br />111 <br />1 <br />ill <br />Well Drilling <br />66 <br />5 <br />330 <br />Well Development <br />31 <br />5 <br />155 <br />Well Equipping <br />2 <br />4 <br />8 <br />Paving <br />Total construction Emissions <br />13 <br />1 <br />13 <br />617 <br />SCAQMD CEQA Threshold (MTCO2elyear <br />10,000 <br />Exceeds Threshold <br />No <br />CEO NEPA Threshold MTC D2e/year) <br />25,000 <br />Exceeds Threshold <br />No <br />0 <br />bpe Appendix B to, CAEFMA Model Out. uts <br />Operational Emissions <br />The electrical energy use for the Proposed Project is estimated at 1,100 kilowatt <br />hours (kWh) per month. Estimated annual operational GHG emissions for the <br />Proposed Project are shown in Table 25, The annual Proposed Project <br />operational GHG emissions would be substantially less than the one year CEQA <br />and NEPA thresholds. It should be noted that the Proposed Project would <br />increase the local supply of groundwater and subsequently reduce the demand <br />for imported water, resulting in a reduction in the GHG emissions associated with <br />the energy required to transport water to the region. <br />mw Mid Basin Centennial Park AefW reject Final EIR 5-93 <br />
