We present the result of the calculation of the geometrical exposure of the surface detector integrated since January 1st, 2004, to September 30th, 2006. The calculation is based on the use of the T2 files, where dead times (hidden and not) of the CDAS are taken into account, by checking the arrival time distribution of the events. We provide also the list of bad periods, which will be updated as new data will be available, until the final data set for building the spectrum will be fixed.
