Before downloading these tables it is strongly recommended that you read the Regional Removal Management Levels User's Guide.

Generic RML Tables

You may need a PDF reader to view some of the files on this page. See EPA’s About PDF page to learn more.

The generic RML tables are available for download in Excel and PDF formats. A Summary Table is provided that contains calculated RMLs corresponding to either a 10-4 risk level for carcinogens or a Hazard Quotient (HQ) of 3 for non-carcinogens. The summary table identifies whether the RML is based on cancer or noncancer effects by including a "c" or "n" after the RML. The Supporting Tables provide RMLs corresponding to a 10-4 risk level for carcinogens and an HQ of 3 for noncarcinogens. RMLs corresponding to an HQ of 1 may be more appropriate for those sites where multiple chemicals are present that have RfDs or RfCs based on the same toxic endpoint. RMLs with an HQ of 1 are equivalent to RSLs with an HQ of 1. These are also provided.
