U.S. EPA’s Proposed Rule for Adding Subsurface (Including Vapor)  
Intrusion to the Superfund National Priorities List: A Summary

by Lenny Siegel
March, 2016

On February 29, 2016 the U.S. Environmental Protection Agency (EPA)  
published a proposed rule, “Addition of a Subsurface Intrusion  
Component to the Hazard Ranking System” in the Federal Register. See
https://www.federalregister.gov/articles/2016/02/29/2016-02749/ 
addition-of-a-subsurface-intrusion-component-to-the-hazard-ranking- 
system). It is taking formal comments on the proposed rule through  
April 29, 2016. Instructions for submitting comments may be found at  
www.regulations.gov.

This long-awaited rule provides an option for adding sites with  
subsurface intrusion of hazardous substances to the “Superfund”  
National Priorities List (NPL), even where other pathways are  
insufficient for listing. For Lenny Siegel’s description of the rule,
