IEEE 980-2013 pdf free.IEEE Guide for Containment and Control of Oil Spills in Substations.
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-polychiorinated 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.
1.2 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 11r 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.

3. Definitions
For ihc purposes of this document, the Ibilowing terms and definitions apply. The IEEE Siandards Dictionary Online’ should be consulted for terms not defined in this clause.
collecting pit: A pit built under oil-tilled equipment to collect any accidental discharge of oil from that piece of equipment.
dewatering: To remove water from.
gallon: One U.S. gallon equals 3.785 liters (L).
harmful quanhih of oil: A discharge of oil that (1) violates applicable water quality standards. (2) causes a film or sheen upon or discoloration of the surface of the water or adjoining shorelines, or (3) causes a sludge or emulsion to be deposited beneath the surface of the water or upon adjoining shorelines.
oil: Any of numerous mineral, vegetable, and synthetic substances and animal and vegetable fats that arc generally slippery, combustible, viscous, liquid or liquefiable at room temperatures, soluble in various organic solvents such as ether but not in water, and used in a great variety of products. especially lubricants and fuels.
oil-containment system: A system designed to collect and retain oil in order to prevent (I) its migration beyond the boundaries of the system and (2) the contamination of navigable waters.
oil spill: Any leak or spillage of oil, regardless of volume and including those that do not reach navigable waters. A spill includes but is not limited to any discharge, leaking, pumping, pouring, emitting, emptying. or dumping of oil.
permeability: The drainage characteristic of soil that denotes its capacity to conduct or discharge fluids under a given hydraulic gradient.
prImar oil containment: A tank or enclosure designed for continuous containment of oil for operating or storage purposes.
retention pit: A pit designed to retain (hold) oil-contaminated liquids.IEEE 980 pdf free download.
