This proposal is a next in the set of proposals aimed on obtaining legacy-level observational datasets on the Milky Way Galactic disk. The ultimate goal of the entire project (which started in AO4-A06 continue in the current AO7 and which we plan to continue it in subsequent AOs) is to have {it model independent} and {it systematics free} measurements of the fluxes in nuclear lines (511 keV annihilation emission 1.8 MeV Al$^{26}$ and 1.17 MeV and 1.33 MeV Fe$^{60}$ lines) and a broad band spectrum of the Galactic background emission which at different energies is provided either by the cumulative emission of faint Galactic sources or by the interaction of low energy cosmic rays with the interstellar medium. Our strategy was supported by INTEGRAL TACs during previous AOs and now we propose to continue the coverage of the Galactic disk with scanning observations. Taking into account the unique combination of properties of INTEGRAL instruments -- broad band coverage large fields of view and possibilities to eliminate the contribution of discrete sources from the total measured photon flux {f the proposed strategy is the best possible usage of the valuable INTEGRAL time}.
