Storage Room with a small window

Hi everyone, Although I read almost all the comments related with the ventilation requirements of the storage rooms, I could not find the exact answer for my question. In our project we have a storage room (definitely will be visited maybe once a month for 10 min and will store no chemicals etc..), with just a small operable window, which is not providing %4 area condition. Some comments say that "Storage Rooms" can be excluded from VRP calculations, but also some refers to ASHRAE 62.1-2007 table for Ra rate to be provided. So my question: Should I exclude this area with a strong narrative for this prerequisite? or The natural ventilation with small window for a storage room will be enough although it is not %4 by area?
