Interceptor Ditch
Have you/can you briefly discuss the operation of the interceptor ditch in the cooling water systems discussion. There is nothing new to discuss, aside from the plume at depth, with the groundwater impacts discussed in my section.
Can we add something like the following as lifted from the ER so that neither you nor I need to explain it:
The interceptor ditch system was designed to restrict westward movement of CCS water by maintaining a seaward groundwater gradient during times when a natural seaward gradient does not exist. During most of the year, a natural seaward gradient does exist. During those times when a westward gradient is measured from the interceptor ditch/CCS and the L-31E
- Canal, pumps located within the interceptor ditch are activated to lower the stage in the interceptor ditch to at least 0.25 feet below the concurrent stage measured in the L-31E, thereby restoring a seaward gradient (ER p. 3-105)
