Schedules 4 through 7 of the Contaminated Sites Regulation (the regulation) provide numerical concentration environmental quality standards for a large number of individual substances. In addition, the Director has established “Nonscheduled Toxic Substances – not present” standards for soil and water. These standards require that soil and water at a site be remediated so that any nonscheduled toxic substance (NSTS) is not present with a concentration in excess of that acceptable to the Director, and that soil to be relocated does not contain any NSTS with a concentration in excess of that acceptable to the Director. The NSTS standards therefore ensure that sites contaminated with toxic substances not specified in Schedule 4, 5 or 6 of the regulation can be effectively remediated and that soil contaminated with toxic substances not specified in Schedule 7 can be relocated under the provision for soil relocation agreements.
