IX. Environmental Impacts
In accordance with the National Environmental Policy Act (NEPA), OSHA has
reviewed this standard for occupational exposure to BD and determined that
this action will have no significant impact on the external environment. The
new standard can be achieved through a combination of engineering controls,
work practices, and respirator use in maintenance situations. OSHA reviewed
the extent to which any of the engineering controls or work practices might
have an environmental impact. OSHA found that these controls will have no
significant adverse impact on the eternal environment because no additional
solid waste would be contaminated with BD and that any new releases to the
external atmosphere would constitute an insignificant increase in emissions.
Indeed, most of the recommended controls would prove advantageous from an
environmental viewpoint. For example, such controls as replacing slip-tube
gauges with magnetic gauges, use of closed loop sampling systems, and the use
of dual mechanical seals all serve to reduce both worker exposures and
emissions to the environment. Other controls, such as exhaust ventilation in
laboratories, leave environmental emissions unchanged.
Based on its review, OSHA concludes that there will be no significant impact
on the environment external to the work place as a result of the promulgation
of this standard.
