"Lenskoye swimming pool water department" = Water Department of Lena watershed (river basin). Lena is the name of big river in Siberia. Gold production includes using a lot of water (like in cyanide leaching) with potential environmental problems, etc. So, the last two licenses are the authorization to use water supply from Lena-river.
P.S. This is an example of blind online translation. The word "pool" ("bassein") has different meanings in Russian: "swimming pool", "watershed" (river basin), or even coalfield ("coal pool")
