1 All values are in µg/g dry weight (dwt) unless otherwise stated. Substance must be analyzed using methods specified in a director’s protocol or alternate methods acceptable to a director.

4 Sensitive site means a sediment site with sensitive aquatic habitat and for which sensitive sediment management objectives apply. Consult Director for further advice.

5 Typical site means a sediment site which is not a sensitive sediment site. Consult Director for further advice.

6 Denotes a sediment quality criteria which is considered less reliable or that could not be fully evaluated.

8 Calculated using data for PCDDs, PCDFs, PCBs and associated PCDD, PCDF and PCB toxicity equivalency factors.

9 Total PCBs includes either the sum of four to seven Arochlor mixtures (i.e. Arochlor 1016, 1221, 1232, 1242, 1248, 1254 and/or 1260) or the sum of > 20 individual PCB congeners. No discrete criterion for Arochlor 1254 was derived, since the existing Canadian Council of Ministers of the Environment interim Probable Effects Level (PEL) for that substance was inconsistent with the PEL provided for total PCBs and the Probable Effects Level (PEL) for Arochlor 1254 was derived using methods different from those used to derive the criterion for total PCBs listed in this schedule.

10 Criterion is set equal to the State of New York, Department of Environmental Conservation, 1994 criterion for the substance.

11 Criterion is set equal to the Washington State, Department of Ecology, 1991 criterion for the substance.
