Content:
rumentation used to monitor and control effluent releases, (2) describe parameters and provide justification of values used to derive effluent release rates and alarm setpoints, including the basis of dilution factors for liquid effluents (in-plant and beyond the point of release in unrestricted areas) and atmospheric dispersion (X/Q) and deposition (D/Q) factors for gaseous and particulate effluents, (3) provide specifications for maximum radioactivity levels in tanks containing liquids and offgas systems and descriptions of protective measures applied to spills and leaks from such components, (4) identify locations of offsite dose receptors and the basis for their selection using the results of annual land use census surveys, (5) describe criteria used to determine the operability of waste treatment systems and requirements in conducting dose projections, such as whenever treatment systems are not fully utilized, or in assessing monthly, quarterly, and yearly doses, and (6) define administrative and operational procedures associated with the implementation of the ODCM. For sites with applicants and licensees operating two or more reactors, each applicant and licensee should include in their respective ODCMs a process for notifying the other licensees on the same site to ensure that, when combined, effluent concentrations and offsite dose limits of 10 CFR Part 20 are not exceeded. The operation of two or more plants will be contributing to and sharing a single dose allocation for members of the public under 10 CFR 20.1301 and 10 CFR 20.1302; 10 CFR 20.1301(e) in complying with 40 CFR Part 190; and liquid and gaseous effluent concentration limits of 10 CFR Part 20, Appendix B, Table 2, Columns 1 and 2, and Note 4 for radionuclide mixtures. The notification process should include the means by which releases of liquid and gaseous effluents can be coordinated and controlled such that all licensees on the site are jointly aware of routine and planned releases, including
