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 3.0 Ms of observations in AO18 and 3 Ms in AO19 to continue our KeyProgram covering areas of the Plane with regular scans every orbit. For these AOs we selected again the section of the Plane incorporating two sky regions centered at l=+/-30 that are both rich in galactic sources (LMXB and HMXB SFXT inparticular) and potential MeV/TeV sources. 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 avery 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 been through AO8-17 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 Atels so that rapid follow-up by the community is possible as has already been demonstrated.
