pplying cooling water to the plant. Based on these and other population modeling studies to date, loss by impingement at or below the report levels should not result in an unacceptable impact to these orgamsms and the ecosystem. Based on existing data, rates of impingement are expected to be less than the reporting levels. Impinge ment at rates exceeding the report levels for periods up to several days does not imply irreversible unacceptable impacts on the fishery, but indicates a sufficient change from normal rates to warrant reevaluation of plant operating limits designed to protect the fishery. Studies of the river ecosystem indicate that continued loss of organisms at rates exceeding report levels may not be compatible with maintaining the existing species com position or population density of the fishery. "**The bases should be supported by reference to appropriate published documents and data held by the licensee. 4.8-21 APPENDIX 1 ACCEPTABLE WORDING FOR SECTION 3.2, "RADIOLOGICAL ENVIRONMENTAL IAONITORING," TECHNICAL SPECIFICATIONS 3.2 Radiological Environmental Monitoring 3.2.1 Monitoring Requirements Objective An environmental radiological monitoring program is conducted to verify projected or anticipated radio activity concentrations and related public exposures.
