Code of Maine Rules › 06 - DEPARTMENT OF ENVIRONMENTAL PROTECTION › 096 - DEPARTMENT OF ENVIRONMENTAL PROTECTION - GENERAL › Chapter 418 - BENEFICIAL USE OF SOLID WASTES › Appendix 096-418-A - SCREENING LEVELS FOR BENEFICIAL USE (mg/kg, dry weight)

Current through 2024-29, July 17, 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.
