Hazard Ranking System Law and Legal Definition
The Hazard Ranking System (HRS) is a mechanism used by the U.S. Environmental Protection Agency (EPA) to evaluate the risks that may be caused to public health and the environment, from releases or threatened releases of hazardous wastes at uncontrolled waste sites.

Any organization or individual can request the EPA to conduct a preliminary assessment. The request should be submitted using the Preliminary Assessment Petition.
