DPR 42 50 306 DPR 60 Report of Plans for Alternate Provisions for an Inonerable Yard Fire Hydrant Hose House This letter is provided in accordance with Section 3.14,F.1 of the Prairie Island Technical Specifications which requires that all yard hydrant hose houses be operable whenever the equipment they are protecting is operable.
Technical. Specification 3.14.F.2 requires that:
If Specification 3.14 F.1 cannot be met, within one hour have sufficient additional lengths of 21/2 inch diameter hose located in adjacent
-OPERABLE yard hydrant hose house (s) to provide service to the unprotected area (s),
y Restore the yard hydrant hose house (s) to OPERABLE status within 14 daye or submit a special report to the Commission within 30 days outlining the cause of the inoperability and the plans and schedule for restoring the houses to OPERABLE status.

placed in adjacent Hydrant Hose Houses #6 and #8 which left no areas unprotected.
In addition, all hose stations inside the Turbine Building and Auxiliary Building have remained in service.
We estimate that the construction in the area will prevent the return to service of Hydrant Hose House #7 until approximately June 30, 1990.
This construction involves excavation and placement of concreto, rebar, and structural steel for the building which will house two additional safeguards diesel generators.
