Basically, tne procedures new limit H2/0, ~ concentraticrs in tne Waste 3as Surge Tank to Region "A" of ne attached figure.

Upon entrance of the system to Region "3" cencentrstions a -eturn to Recion " A" must te mace wi tnin 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />. I' no time will One Was te'3as System :e operated in Regicn "C".

C;ntinuous monitoring of tre Surge Tank will be acr.e while tne system is in cperation. If tne H;/03 analy:er is Out of service tnen tne plant cnecasts will take grab sam les every 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> curing Waste 3as Sys tem operation.
