Air Pathways from

Hazardous Waste Sites

I. INTRODUCTION

This chapter addresses the potential for hazardous air emissions from
environmental remediation sites. These emissions can occur at hazardous
spill locations, at undisturbed remediation sites, and during cleanup of
remediation sites under the Comprehensive Environmental Response,
Compensation, and Liability Act (CERCLA) or the Superfund Amendments
and Reauthorization Act (SARA). Air emissions may pose a potential health
risk at these sites.
The U. S. Environmental Protection Agency (EPA) developed the Hazard
Ranking System (HRS) (1) to determine priorities among releases, or threat-
ened releases, from remediation sites. The HRS applies the appropriate
consideration of each of the following site-specific characteristics of such
facilities:
• The quantity, toxicity, and concentrations of hazardous constituents
that are present in such waste and a comparison with other wastes.
• The extent of, and potential for, release of such hazardous constituents
to the environment.
