e. 2.3.3 Suspendedannd Total Dissolved Solids Limits should be provided for the dissolved and suspended solids in the plant effluents. Limits should be stated for either the specific chemicals 'or for tile suspended and total dissolved solids discharged. Limits should be expressed as maximum effluent concentra tions and estimates of total annual release. Units should provide protection against accelerated eutrophication,. increased water turbidity, and other reduction in water quality. 4.8-6 K .2.3 Chemical 2.3.4 pH. Limits should be provided to maintain effluent pH within a range compatible with indigenous aquatic life. * 2.3.5 Other Chemicals that Affect Water Quality Limits should be provi4dd for all other chemical releases that have potential for reducing receiving water quality and causing adverse environmental impact. For example, lower limits on dissolved oxygen and upper limits on oxygen demand in the plant effluent may be appropriate. 2.4 Radioactive Effluents Limiting conditions for operation should be estab lished for all plant radioactive discharges to keep levels of radioactive material in effluents to unrestricted areas as low as is reasonably achievable. These limiting conditions for operation should be applied to radioactive liquid and gaseous discharges to be within the limits of 10 CFR Part 20 and to comply with the provisions of 10 CFR Part 50. Surveillance and monitoring programs should be established to provide data on quantities of radioactive material released in liquid and gaseous effluents to ensure that radioactive releases are maintained within the regulatory provisions cited above. These programs should be applied to radioactive liquid and gaseous materials released from the plant to meet General Design Criteria 60 and 64 of Appendix A to 10 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
