Guide for Containment and Control of Oil Spills in Substations
|Publication Date:||10 December 2013|
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.
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.
