This high-quality data set allows us to extract accurate ionic column densities and determine an electron number density of ne=103.3±0.2cm-3 for the main outflow absorption component. The heavily reddened spectrum of SDSS J0318-0600 requires purely silicate dust with a reddening curve characteristic of predominately large grains, from which we estimate the bolometric luminosity. We carry out photoionization modeling to determine the total column density, ionization parameter, and distance of the gas and find that the photoionization models suggest abundances greater than solar. Due to the uncertainty in the location of the dust extinction, we arrive at two viable distances for the main ouflow component from the central source, 6 and 17kpc, where we consider the 6kpc location as somewhat more physically plausible. Assuming the canonical global covering of 20% for the outflow and a distance of 6kpc, our analysis yields a mass flux of 120M/yr and a kinetic luminosity that is ∼0.1% of the bolometric luminosity of the object. Should the dust be part of the outflow, then these values are ∼4x larger. The large mass flux and kinetic luminosity make this outflow a significant contributor to active galactic nucleus feedback processes. Description: During 2006 October (September 30 to October 22), we obtained eight echelle spectra, each with an exposure time of 2850s, of the object SDSS J0318-0600 (z=1.967, Schneider et al. 2007, Cat. VII/260, RA=031856.7, DE=-060037.4) with the VLT. The spectra were taken using the UV-Visual Echelle Spectrograph (UVES) with a slit width of 1.0" which gives a resolving power of ∼40000, and a central wavelength position of 5800 and 3460Å for the red and blue detectors respectively.
