1. Introduction

Congress enacted the current Bankruptcy Code, Sections 101 through 1502 of Title Eleven of the United States Code (as amended, the “Bankruptcy Code”), in 1978, and it took effect late in 1979. Many important federal environmental statutes were enacted around the same time, e.g., Congress enacted the Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) in 1980. Thus, Congress did not fully consider environmental liability schemes when it created the bankruptcy code.
