SPL Resource Page



This webpage provides supporting information regarding the development of the Substance Priority List, as well as, expanded information on this list and past lists.

Support Document to the 2013 Priority List of Hazardous Substances - This Support Document describes the methodology used to generate the substance priority list.

Detailed Data Table for the 2013 Priority List of Hazardous Substances - This detailed data table provides a breakdown of the components that determine the total point scores used to rank candidate substances for the substance priority list.

Changes in prioritized substances relative to the last SPL – Substances new to the 2013 Substance Priority List, and substances that were on the previous SPL but are not on the 2013 List.

Full SPL Data - To be updated with 2013 SPL Report soon - A spreadsheet with SPL detail in a filterable numeric format along with additional supporting information, such as the standard deviations for geometric means, number of data points in the means, and the number of sites from which concentration data was collected. The spreadsheet covers all past SPLs (1987 to 2011) and includes summary statistics for the dataset as a whole. Please refer to the cover sheet for more information on the data.

SPL Toxicity Values - A spreadsheet with a breakdown of the Toxicity/Environmental Scores (TESs) and a listing of Reportable Quantities used for the SPL.

Methodology for Toxicity/Environmental Scores - Describes the methodology used to determine the Toxicity/Environmental Scores (TESs) for the Substance Priority List.

SPL Federal Register Notices and Run Dates – A table of Federal Register Notices (FRNs) announcing the release of updates to ATSDR SPLs. It includes links to the FRNs themselves. The table also includes the date that the SPL was generated each year.
