City of Pleasanton–10x Genomics Project Environmental Checklist and Initial Study/Mitigated Negative Declaration Environmental Evaluation FirstCarbon Solutions 19 C:\Users\cso\Downloads\21480024 10x Genomics Project Full Screencheck ISMND+EC+LS+MT+DB+EL (1).docx SECTION 2: ENVIRONMENTAL CHECKLIST AND ENVIRONMENTAL EVALUATION Environmental Factors Potentially Affected The environmental factors checked below would be potentially affected by this project, involving at least one impact that is a “Potentially Significant Impact” as indicated by the checklist on the following pages. Aesthetics Agriculture and Forestry Resources Air Quality Biological Resources Cultural Resources Energy Geology/Soils Greenhouse Gas Emissions Hazards/Hazardous Materials Hydrology/Water Quality Land Use/Planning Mineral Resources Noise Population/Housing Public Services Recreation Transportation Tribal Cultural Resources Utilities/Services Systems Wildfire Mandatory Findings of Significance Environmental Determination On the basis of this initial evaluation: I find that the proposed project COULD NOT have a significant effect on the environment, and a NEGATIVE DECLARATION will be prepared. I find that although the proposed project could have a significant effect on the environment, there will not be a significant effect in this case because revisions in the project have been made by or agreed to by the project proponent. A MITIGATED NEGATIVE DECLARATION will be prepared. I find that the proposed project MAY have a significant effect on the environment, and an ENVIRONMENTAL IMPACT REPORT is required. I find that the proposed project MAY have a “potentially significant impact” or “potentially significant unless mitigated” impact on the environment, but at least one effect 1) has been adequately analyzed in an earlier document pursuant to applicable legal standards, and 2) has been addressed by mitigation measure based on the earlier analysis as described on attached sheets. An ENVIRONMENTAL IMPACT REPORT is required, but it must analyze only the effects that remain to be addressed. I find that although the proposed project could have a significant effect on the environment, because all potentially significant effects (a) have been analyzed adequately in an earlier EIR or NEGATIVE DECLARATION pursuant to applicable standards, and (b) have been avoided or mitigated pursuant to that earlier EIR or NEGATIVE DECLARATION, including revisions or mitigation measures that are imposed upon the proposed project, nothing further is required.
