The survey of the Galactic Plane has continued as one of the main INTEGRAL scientific objectives because of the scientific potential of both new source discovery and detailed monitoring of already known sources that will provide a legacy archive and a basis for future missions. We propose for a total of 2Ms of observation in AO20 to continue our previous approved Key Program covering areas of the Plane with regular scans every orbit. For this AO we selected again the section of the Plane incorporating two sky regions centred at l=+/-30 that are both rich in galactic sources (LMXB and HMXB SFXT in particular) and potential MeV/TeV sources. In view of the new z-flip mission strategy our priority is still this but we are flexible to extend the program along the Plane as during the AO18/AO19. Our purpose is to regularly monitor known systems as well as to dramatically enhance the chances of discovering new systems or new outbursts from known sources. This program will allow a rapid response to bright events and a detailed study of faint transients and their long-term activity. Such a programme will be of high value to a very large fraction of the high-energy astronomy community stimulating science immediately and furthermore contributing greatly to the INTEGRAL legacy.In order to maximise the engagement of the scientific community we will continue to make the observations public immediately. The team will make as it has done through AO8-19 the scw-resolution IBIS and JEM-X light curves (in two energy bands) and per-revolution mosaic images publicly available through the web as soon as possible. Any interesting source behaviour that emerges from our observations will be announced promptly in the usual way through Atels1 so that rapid follow-up by the community is possible as has already been demonstrated.
