The response to an oil spill often results in the rapid generation and accumulation of large quantities of oily waste. Emulsified oil, oiled sand, gravel and entrained debris can increase the volume of waste to many times the volume of oil originally spilt. This waste often exceeds the capacity of the locally available waste management infrastructure. As a result, the management of response-related wastes can become the most time- demanding and costly aspect of an oil spill. This document sets out the principles involved in identifying and planning for management of the various waste streams listed above. Wastes from a variety of sources (offshore and onshore spills worldwide, upstream and downstream operations from oil exploration and production, processing, refining, transport and storage activities) are considered.
