eds or thousands of kg/ha/yr could cause damage sufficient to suggest the need for changes of tower-basin salinities or a reevaluation of tower design, depending on the amount of land impacted and the uniqueness of the terrestrial ecosystems expected to be exposed to drift deposition. (2) Consider the detrimental effects increased fogging could have on local vegetation if the increase in humidity induces an increase in fungal or other phytopathological infections. Increased icing can cause physical damage to vegetation due to increased structural pressure on tree branches or by damaging fruit or leaf buds. ` Use an order of magnitude approach as follows to analyze operational impacts from fog or ice: - Fogging or icing of vegetation on the order of a few hours per year is generally not severe. - Fogging or icing on the order of tens of hours per year may cause detectable damage to vegetation. - Fogging or icing occurring for hundreds of hours per year could be severe enough to suggest the need for design changes, depending on the amount of land impacted and the uniqueness of the terrestrial ecosystems expected to be exposed to drift deposition. ` Consider soil salinization: - The risk from this source is generally considered to be low. - In arid areas (deserts), salts could accumulate in soils over long time intervals and cause damage. (3) Consider the impact to terrestrial biota when new shoreline habitats are created along ponds and reservoirs built for cooling purposes. Riparian tree/shrub communities that form around these new ponds or reservoirs may attract “important” species. If endangered or threatened species could be affected, agency level formal or informal consultation with the U.S. Fish and Wildlife Service under Section 7 of the Endangered Species Act is required. IV. EVALUATION FINDINGS NUREG-1555 5.3.3.2-6 October 1999 Input to the EIS should accomplish the following objectives: (1) public disclosure of any expected impact to the terrestrial
