The aim of the Preliminary Site Investigation (PSI) was to identify site contamination issues associated with past and present land use at the site and surrounding sites which may significantly impact the future use or development of the site, or pose probable human health and/or environmental risks. During the mid to late 1970s, the site ownership changed hands resulting in the clearing of all existing improvements, and a warehouse occupying the eastern portion of the site was constructed. It was at this time that publishing started at the site and this warehouse is now the current main office building at the site. A site representative indicated that a decommissioned, likely unleaded petrol, UST is present at the site. The location of the UST is not known, however, a concrete cut identified in the southwest corner of the site may be evidence of the decommissioning.
