The Fact Sheet discusses the revised HRS which retains the same cutoff score and basic approach as the original HRS, while incorporating SARA requirements as well as improvements identified as necessary by EPA and the public. The revised HRS retains the ground water, surface water, and air pathways, drops the direct contact and fire/explosion pathways, and adds a fourth pathway, soil exposure. Several key provisions of the revised HRS make it more comprehensive. Other provisions make the revised HRS more accurate. The complexity and scope of the issues involved in revising the HRS required EPA to get widespread input. The majority of the commenters believed that the revised HRS represented an improvement over the original HRS. The result is a revised HRS that is a practical and effective tool in identifying the nation's worst hazardous waste sites.
