  We report limits on the Galactic foreground emission contribution to the
Background Emission Anisotropy Scanning Telescope (BEAST) Ka- and Q-band CMB
anisotropy maps. We estimate the contribution from the cross-correlations
between these maps and the foreground emission templates of an H${\alpha}$ map,
a de-striped version of the Haslam et al. 408 MHz map, and a combined 100
$\mu$m IRAS/DIRBE map. Our analysis samples the BEAST $\sim10^\circ$
declination band into 24 one-hour (RA) wide sectors with $\sim7900$ pixels
each, where we calculate: (a) the linear correlation coefficient between the
anisotropy maps and the templates; (b) the coupling constants between the
specific intensity units of the templates and the antenna temperature at the
BEAST frequencies and (c) the individual foreground contributions to the BEAST
anisotropy maps. The peak sector contributions of the contaminants in the
Ka-band are of 56.5% free-free with a coupling constant of $8.3\pm0.4$
$\mu$K/R, and 67.4% dust with $45.0\pm2.0$ $\mu$K/(MJy/sr). In the Q-band the
corresponding values are of 64.4% free-free with $4.1\pm0.2$ $\mu$K/R and 67.5%
dust with $24.0\pm1.0$ $\mu$K/(MJy/sr). Using a lower limit of 10% in the
relative uncertainty of the coupling constants, we can constrain the sector
contributions of each contaminant in both maps to $< 20$% in 21 (free-free), 19
(dust) and 22 (synchrotron) sectors. At this level, all these sectors are found
outside of the $\mid$b$\mid = 14.6^\circ$ region. By performing the same
correlation analysis as a function of Galactic scale height, we conclude that
the region within $b=\pm17.5^{\circ}$ should be removed from the BEAST maps for
CMB studies in order to keep individual Galactic contributions below $\sim 1$%
of the map's rms.
