cy of samples and measurements; and methods of data evaluation. Reporting Requirements A report level should be established for each measured environmental parameter. If a report level for a parameter cannot be established, justification should be provided. Report levels are warning notices of impending unacceptable environmental stress. They should be established at a level above the normal fluctuations of a given parameter, but low enough to permit remedial action to be taken before significant or irreversible damage has occurred. Bases Present the basis for the program element objective and show its relationship to the overall environmental surveillance program. Discuss the rationale for selecting sampling locations, sampling frequency, and data evaluation methods, and show how the program element will fulfill the objective. An example of an environmental surveillance program element is appended as Example 2. 3.1 Nonradiological Surveillance These program elements should be designed to detect and measure the nonradiological impact of plant operation on environmental systems that (1) are potentially subject to alteration by plant operation and (2) are significant to the quality of animal (including human) and plant life in the power plant environs. Biota that should be surveyed, in most. cases, are those identified in Section 2.2 of Regulatory Guide 4.2, "Preparation of Environmental Reports for Nuclear Power Plants," as "important species." Organization of program elements into abiotic and biotic subdivisions, as shown below, is recommended. 4.8-7 3.1.1 Abiotic a. Aquatic (I) Chemical Discharges. Monitor the concen tration and dispersion of specific chemicals, suspended solids, and total dissolved solids in the receiving waters. Chemical discharges include all dissolved and particulate materials released by the plant to the receiving waters at concentrations in the effluent above ambient and may include biocides, corrosion inhibitors, heavy metals, corrpsion
