ternatives. ` ESRP 10.1. Provide a summary of the unavoidable impacts to terrestrial ecosystems that are predicted to occur as a result of operation of heat-dissipation systems. ` ESRP 10.2. Provide a summary of irreversible and irretrievable commitments of terrestrial biota that are predicted to occur as a result of the operation of heat-dissipation systems. Data and Information Needs The type of data and information needed will be affected by site- and station-specific factors, and the degree of detail should be modified according to the anticipated magnitude of the potential impacts. The following data or information should be obtained: ` concentration and chemical composition of dissolved and suspended solids in cooling tower basins or spray canals on a seasonal basis (from ESRP 3.4.2) ` isopleths of deposition at ground levels on a seasonal basis. Isopleths should extend to values at least as low as 1 kg/ha/mo (from the environmental report [ER] and ESRP 5.3.3.1). ` a list and description of the “important” terrestrial species and habitats that may be affected by the heat-dissipation system (from ESRP 2.4.1) ` descriptions of natural and managed plant communities on the site and within offsite isopleths above 20 kg/ha/yr (from ESRPs 2.4.1, 5.3.3.1, and the site visit) ` annual precipitation and its dissolved solid concentration within the drift field (from the ER) ` prediction of increased frequency and distribution of fog and icing (from ESRP 5.3.3.1) ` shoreline vegetation expected to develop along the shore of new cooling lakes and ponds (from the ER and consultation with Federal, State, and local agencies) ` proposed other uses of cooling ponds and reservoirs (from the ER).

ACCEPTANCE CRITERIA Acceptance criteria for the review of impacts on terrestrial ecosystems from the heat dissipation system are based on the relevant requirements of the following: ` 10 CFR 51.45 with respect to ERs and the analysis of potential
