Appendix 096-418-A - SCREENING LEVELS FOR BENEFICIAL USE (mg/kg, dry weight)

Universal Citation: 06 ME Code Rules § 096-418-A

Current through 2024-38, September 18, 2024

The values in Appendix A were derived using the standard risk assessment protocols of the U.S.E.P.A. Acceptable risk levels were set at one-half the risk standard used by the Department for clean up of sites contaminated with hazardous substances; that is, Appendix A levels are set at the risk standard of this rule. Appendix A screening levels are set at the lowest level for all the routes of exposure that most likely will drive the risk at beneficial use sites: incidental ingestion of the secondary material, skin contact with the secondary material, inhalation of the secondary material in dust or paper, or leaching of contaminants from the secondary material into groundwater and the subsequent ingestion of the groundwater. For the direct ingestion, contact, and inhalation routes of exposure, values were calculated using the methodology in U.S.E.P.A.'s Regional Screening Levels (RSLs) for Chemical Contaminants at Superfund Sites (June 2017). For the leaching to groundwater pathway, levels were calculated using the methodology in Appendix D of the Department's Remediation Guidelines for Petroleum Contaminated Sites in Maine (amended May 23, 2014). This methodology uses the SESOIL and AT123D models, and the 34 chemicals where this approach determined the screening level are marked by double asterisks in the line number column. The 5 hydrocarbon fractions marked by triple asterisks in the line number column were also based on the leaching to groundwater pathway.
