Definition

The Hazard Ranking System (HRS) is used by the U.S. Environmental Protection Agency (EPA) to place uncontrolled waste sites on the National Priority List for action under the SuperFund Act (CERCLA).

Additional Info

Waste sites are placed on the National Priorities List (NPL) using a set of predefined criteria, one of which is the HRS rating. Scores can be determined electronically using the EPA's Quickscore software (Windows only).

The background and history of the HRS, as well as its role in the SuperFund program, is discussed in considerable detail in Chapter 4 of the National Research Council's 1994 publication Ranking Hazardous-Waste Sites for Remedial Action which is available for free download at https://doi.org/10.17226/4781.

SDS Relevance

Some of the information assessed by the HRS is the same information that is found on Safety Data Sheets. After all, a hazardous waste is typically generated after one uses a hazardous chemical. Therefore, one will sometimes find certain HRS and SDS information in the same sources.

Keep informed about workplace hazards with proper labeling techniques and safety posters available from Safety Emporium.
