as standards, in accordance with detailed rulemaking procedures spelled 
out in the Act. Among the policy questions which would have to be 
resolved in contemplating this step are: (1) whether OSHA would agree 
to an outright ban of some activities since it has never in the past 
actually prohibited a total activity, and (2) whether OSHA should give 
priority to establishment of these standards over others that have been 
awaiting promulgation, taking into account the statutory test of " . . . 
urgency of the need for mandatory safety and health standards for 
particular Industries, trades, crafts, occupations, businesses, workplaces 
or work environments." 
ENVIRONMENTAL PROTECTION AGENCY 
The Toxic Substances Control Act (TSCA) , primarily administered by 
EPA, was enacted in October 11, 1976, effective January 1, 1977. Section 6 
of the TSCA states in part that: 
"If the Administrator [of EPA] finds that there is 
a reasonable basis to conclude that the manufacture, 
processing, distribution in commerce, use, or disposal 
of a chemical substance or mixture, or that any com- 
bination of such activities, presents or will present 
an unreasonable risk of injury to health or the 
environment, the Administrator shall by rule apply one 
or more of the following requirements to such substance 
or mixture to the extent necessary to protect adequately 
against such risk using the least burdensome requirements: 
(1) A requirement (A) prohibiting the manufacturing, 
processing, or distribution in commerce of such substance 
or mixture, or (B) limiting the amount of such substance 
or mixture which may be manufactured, processed, or 
distributed in commerce.
