Over the past several years, considerable public and private efforts in this country have been directed at reducing the risk of cancer that human exposure to high levels of radon gas poses. These efforts appear to have succeeded in raising public awareness of radon and in increasing testing for radon. For the most part, however, these efforts have been directed toward homeowners and have not addressed the problem of radon in residential rental properties. Yet, in 1989, nearly 34 million homes—over one-third of all housing units in the country—were rental units.

Editors' Summary: On June 29, 1998, EPA published its PCB Mega Rule, a comprehensive revision of TSCA regulations that govern the remediation and disposal of PCB-contaminated material. The PCB Mega Rule affords the regulated community the option of remediating such material under self-implementing provisions or developing risk-based site-specific remedial measures that generally require Agency approval.

Editors' Summary: After TSCA was enacted in 1976, some commentators described it as the most powerful of all the environmental laws. Congress intended it to provide for the comprehensive and direct control of commercial chemicals' potential health or environmental effects in a true cradle-to-grave tracking system. Indeed, it was the single law addressing toxic substances that could cover all areas of environmental regulation, supplementing sections of existing toxic substances laws. In the 17 years since its enactment, however, TSCA has not fulfilled these goals or expectations.
