SinceourcurrentT/SreliefexpiresonFebruary28,1987,werequested thatyourreviewbeperformed onanexpedited basis.WewereinformedbyyourstaffonJanuary12,1987thattheNRCstaffreviewoftheloadblockdropanalysismaynotbecompleted byFebruary28,1987,andwewereaskedtorequestaT/SchangetodeletetheFebruary28,1987datefromthefootnoteofT/S3.9.7.Deletingtheexpiration datefromthefootnotewouldmeanthattheprovisions ofdeenergizing themainhoistandnoloadonthemainhookremaineffective.
