Description / Abstract:
This guide discusses the significance of oil spillage
regulations in electric supply substations; identifies the sources
of oil spills; discusses typical designs and methods for dealing
with oil containment and control of oil spills; and provides
guidelines for preparation of a typical spill prevention control
and mitigation plan. This guide applies only to non-polychlorinated
biphenyl (non-PCB) insulating oil.
It is not the intent of this guide to interpret governmental
regulations or the applicability of the oil containment systems
presented with respect to compliance to those regulations.
Interpretation is left to each individual user.
Purpose
Containment, control, and mitigation of oil spills are a concern
for owners and operators of electric supply substations. The
environmental impact of oil spills and their mitigation is
regulated by governmental agencies, necessitating increased
attention in substations to the need for secondary oil containment.
Beyond the threat to the environment, mitigation costs associated
with oil spills continue to escalate, and the adverse community
response to any spill is becoming increasingly unacceptable. This
guide identifies some governmental regulations, the sources of oil
spills, and typical methods and plans used to contain, control and
mitigate them.
