CFR Part 50 and, if applicable, the guidelines of Regulatory Guide 1.21, "Measuring, Evaluating, and Reporting Radioactivity in Solid Wastes and Releases of Radioactive Materials in Liquid and Gaseous Effluents from Light-Water-Cooled Nuclear Power Plants." 3 ENVIRONMENTAL SURVEILLANCE The objective of the environmental surveillance pro gram is to determine the nature and extent of changes in the ecosystem that may result from plant operation. The program should cover elements of the ecosystem for which a causal relationship between plant operation and adverse change is established or strongly suspected. The listing of environmental parameters to be monitored in the surveillance program in this section is illustrative and not all-inclusive. Periodic evaluation of the findings of the surveillance program will provide the basis for modification of the program to ensure that the surveil lance effort is sufficient and justified when compared to current assessment of the effect that plant operation is having on the environment. Any modification of surveil lance programs should be accompanied by submission of a formal change in the environmental technical specifica tions per Section 5.6.3. A narrative summary should be provided at the beginning of Oils section. The summary should describe the overall environmental surveillance program and demonstrate how the program will meet the stated objective. Each surveillance program element should be pre sented in a concise narrative manner using the following format: Objective Describe the environmental parameters to be investi gated and the information the surveillance program will supply. Specification Describe what is to be done. Include essential features such as sampling and measurement techniques; locations, numbers, and frequency 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
