"Determination of significance" (DS) means the written decision by the responsible official of the lead agency that a proposal is likely to have a significant adverse environmental impact, and therefore an EIS is required (WAC 197-11-310 and 197-11-360). The DS form is in WAC 197-11-980 and must be used substantially in that form.
