1. Regulatorv Limits Action is required if the rate of release of radioactive materials, when averaged over a three-month period, is such that these quantities, if continued at the same release race for a year, would exceed twice the design objectives. Design objectives are:

a. Fission and activation gases (and all other radioactive isotopes except halogen and particulate isotopes with half-lives greater than 8 days) in gaseous releases:

3 41 <

_ 1300 m /sec MPC g

b. Iodines and.particulates with half-lives greater than 8 days in gaseous releases:

Qi <

_ 67 m /sec i i

c. Liquid Effluents:

1. Annual total quantity of radioactive material in liquid waste, excluding tritium and dissolved gases, of 5 Ci per unit.

2. Annual average concentration of radioactive material in liquid waste, prior to dilucion in the Mississgppi River, excluding tritium and dissolved gases, of 2 X 10 pC1/ml.

3. Annua 1' average concentration of tritium in liqug waste, prior to dilution in the Mississippi River, of 5 X 10 pC1/ml.

2. Maximum Permissible Concentrations a.- Fission and activation gases (and all other radioactive isotopes except halogen and particulate isotopes with half-lives greater than 8 days) in gaseous releases:
