To preserve the absorbing state clusters with at least one site occupied are renormalized into a one occupied site and clusters with all sites empty are renormalized into a one empty site. We have obtained the phase diagram as well as the critical exponent related to the spatial correlation length.14 pages, 2 figuresCondensed Mattertext
