SPOKANE TRIBAL HAZARDOUS SUBSTANCES CONTROL ACT
APPENDIX C
Sediment cleanup levels for the Protection of Human Health and Sediment-Dwelling Organisms
The following discussion and Table, indicate the minimum numerical cleanup levels for contamination in
sediments caused by the listed hazardous substances.
(a) The Tribe has employed the exact same exposure factors and assumptions, herein, that were
used to calculate cleanup levels for soils that are protective of Human Health (Appendix B).
(b) Therefore, cleanup levels for sediments that are protective of human health are equivalent to
those of soils, and have not been repeated herein (Consult Appendix B).
(c) Table 1 indicates the sediment cleanup levels for the protection of sediment-dwelling organisms.
These standards are modeled after those employed by the Confederated Tribes of the Colville
Indian Reservation (CTCIR).
