Appendix A-4 Sediment Cleanup Levels The following charts, Chart I and Chart II, indicate the minimum numerical cleanup levels for contamination in sediments caused by the listed hazardous substances.Chart I indicates the sediment cleanup levels for the protection of human health. These cleanup levels are given in µg of contaminant/kg of organic carbon.Chart II indicates the sediment cleanup levels for the protection of sediment-dwelling organisms. The cleanup levels in Chart II are given in the units shown in the chart. To the extent that there are two sediment standards for the same compound the lower standard shall control. Response actions must also comply with the following narrative standards for sediments.In the case of a substance for which there is no numerical standard in Chart I, the following narrative standard shall apply:Bioaccumulative substances shall not occur in sediments, either singly or in combination at concentrations that cause, or can reasonably be expected to cause, injury to human health or biological resources including sediment-dwelling organisms and biological communities.In the case of a substance for which there is no numerical standard in Chart II, the following narrative standard shall apply:Toxic substances shall not occur in sediments, either singly or in combination, at concentrations that cause, or can reasonably be expected to cause, injury to human health or biological resources including sediment-dwelling organisms and biological communities.These numerical sediment cleanup levels and narrative sediment cleanup levels shall remain in effect until the Department amends them. The Department may also establish more stringent cleanup levels for a specific site, when, based on a site-specific evaluation, the Department determines that such levels are necessary to protect human health and the environment.For substances not listed below, refer to the EPA Region III BTAG Freshwater Sediment Screening Benchmarks.Chart I.
