The format for each section is further <br /> described below. <br /> ,f <br /> Determination of Significance 1 <br /> As identified herein, general definitions of the various levels of significance used to A <br /> characterize project impacts are as follows: " <br /> Less-than-Significant - The impact would cause no substantial change in the <br /> existing or projected future environment; therefore, no mitigation is required. Said <br /> another Way, while there may be some associated impact, it is insignificant or Ij <br /> acceptable as defined by the applicable thresholds of significance. <br /> �i <br /> i Potentially Significant- May be used to denote an element of speculation. Where <br /> used, the applicable circumstances are described. Potentially significant impacts i <br /> i are treated as significant impacts. See the discussion below. <br /> i <br /> F Significant - Under CEQA, a significant effect is defined, as a substantial, or <br /> potentially substantial, adverse change in the environment (Public Resources Code <br /> 21068). The Guidelines implementing CEQA direct that this determination be made i' <br /> p g <br /> by the decision-making body, and that it be based on scientific and factual data, to <br /> the extent possible. As such, the specific criteria for determining the significance <br /> of a particular impact for this project are identified prior to the project-specific impact <br /> analysis in each section, and are consistent with significance criteria set forth in the j <br /> guidelines implementing CEQA. The Guidelines go on to state that an "ironclad" i <br /> definition of significant effect is not possible because the significance of an activity <br /> �-, may vary with the setting. Significant impacts can be mitigated to less-than- <br /> . , • significant levels by implementation of identified mitigation measures. l <br /> + 4 i <br /> i <br /> I� <br /> Draft Environmental Impact Report 4-1 ER-96-3 <br />
