Are the impacts of the response alternative on threatened or endangered species and habitats acceptable?
“Yes” if species are absent or impacts are within an acceptable range. “No” if impacts are unacceptable. ? “Unknown” if species are present and impacts occur but effects cannot be determined. Alternatives A through Z: Criterion rating: At this time, no rare species are known to inhabit the areas likely to be impacted by any of the proposed alternatives. In addition, the developed nature of the area reduces (but does not eliminate) the likelihood that the area supports rare species. Therefore, the potential for impacts to rare species by any of the alternatives is minimal. I.B. Environment: 2. Are the impacts of the response alternative within hydrological and ecological thresholds? Yes No Other than potential changes in surface water levels and changes in pond flux, ecological thresholds established for surface water bodies cannot be predicted by the groundwater flow model for a given alternative. Therefore a set of hydrological thresholds, selected with ecological thresholds in mind,
