'he discussion of the difficulties experienced in'maintaining flows introduces uncertainty, as to what the actual cooling water flow will be with two units in service.

1fith the new intake in service what will the flow be.through each unit2 Mill this be maintained by throttling back pumps2 Apparently higher flows could be employed.

At what reduced flow and corresponding elevated temperature rise will intake pipeline cleaning procedures be initiated2 291. 2 Discuss recirculation of discharged water to the new intake pipeline.

Also show the details of the mitigation area to be provided as compensation for the destruction of mangrove swamp.

On the same photo, if appropriate, or on other photo identify boundaries of areas to be used far 'the disposition of dredge spoils resulting from the construction of the third intake pipeline, headwall, and wi'dening of the intake canal.

291 l3 Provide the following information:

a.

The month the mangrove swamp mitigation action is to take place.

b.

The kind of equipment used to. perform the mitigation action (e.g.,

backhoe, dragline).

c.

The names of the specific native species to be planted.

"291.14.

Conduct

a. survey of the mangrove. swamp to determine whether any 1eather

.ferns are in area to be destroyed.
