The Part 7 Cleanup Criteria Rules were rescinded on December 31, 2013. Taking their place are new cleanup criteria rules, numbered from 299.1 to 299.50, which became effective on December 30, 2013.

The Part 201 groundwater and soil cleanup criteria and screening levels, criteria footnotes and the toxicological and chemical-physical properties of the hazardous substances are now located in the following rules:

• R 299.44 Generic groundwater cleanup criteria (Table 1).
• R 299.46 Generic soil cleanup criteria for residential category (Table 2).
• R 299.48 Generic soil cleanup criteria for nonresidential category (Table 3).
• R 299.49 Footnotes for generic cleanup criteria tables.
• R 299.50 Toxicological and chemical-physical properties (Table 4).

The criteria tables, toxicological and chemical-physical data, and footnotes, as presented in the Cleanup Criteria Requirements for Response Activity Rules, have been reformatted and are presented here as Excel and PDF files. Some groundwater and soil cleanup criteria and screening levels have changed as compared to the previous September 28, 2012 release of these tables under the Part 7 rules. These changes are noted in the Criteria Changes document accessible below. Most of the changes are the result of presenting the risk-based value instead of defaulting to the Csat value for the (C) footnoted criteria. The Groundwater Contact Criteria, the Soil Criteria Protective of Groundwater Contact, and the Acute Inhalation Screening Levels have been eliminated. A few minor errors were identified in the Part 201 cleanup criteria rules tables and are presented in the Criteria Errata Sheet accessible below.

The criteria tables provided have been updated to include revisions or additions to the surface water quality standards, that are the GSI criteria, consistent with the statute.
