IntheLAR,wewouldliketoqualifythattheretyped,proposedTSare technicallycorrect,butnotpublicationready. Thatmeansthatpage numbers,pagebreaks,insertionofintentionallyblankpages,indenting, tablecolumnspacing,etc.,maychangeinthefinalTS.Inaddition,thereare openLARsthataffectsomeoftheaffectedTSpages.Constellationwill submitfinal,publicationreadypagespriortoLARapproval,consistent withthepracticeofprovidingfinalpagesforotherLARs.

WewouldliketousethisapproachbecausethechangestoSection3.3are significant(multiplespecificationsremovedandnewonesinserted)andthe LGSTSusecontinuouspagenumberswithinaSection. Inaddition,theLGS TSusedoublesidedpageswithspecificationsandtablesbeginningonleft facingpages,requiringtheuseofintentionallyblankpages. Therefore,it wouldbemostefficienttomakeanychangesrelatedtoresolutionofNRC RAIsbeforecreatingthefinalTS.
