Replacement of the conditioning tank with the simple process <br /> slurry delivery line significantly reduces spill potential by markedly improving the <br /> flow through this area of the process and drastically reducing the chance for any <br /> upset conditions. The simple process slurry delivery line will have a lime injection <br /> port constructed as an in-line system therefore no holding tank or mixing container <br /> will exist. <br /> Comment 2:As required by the Corrective Actions of Violation MV-2016-035,please <br /> specify how the TR-81 addresses enhancements to the capacity of the primary <br /> containment. <br />
