ZESCO Limited, a vertically integrated parastatal utility company established in 1970, responsible for the generation, transmission, distribution and supply of electricity intends to engage a service provider to dispose of Polychlorinated Biphenyls (PCBs).
The corporation has massive investments in generation, transmission and distribution infrastructure spread across the whole country, which property had in the past generated Polychlorinated Biphenyls (PCBs). Polychlorinated biphenyls (PCB) are one of the twenty two (22) Persistent Organic Pollutants (POPs). These are chemical substances which persistently bio accumulate, and pose the risk of causing adverse effects to human health and the environment. PCBs have been widely used as additives to oils, as coolants in transformers, capacitors and other electrical equipment, hydraulic machinery and other applications where chemical stability has been required for safety, operation or durability. PCBs are also widely used in a variety of other products such as carbonless paper, adhesives and hydraulic fluids.
PCBs are amongst the most widespread environmental pollutants, having been detected in virtually all environmental media. PCBs are not only persistent, but are also toxic. They bio-accumulates in aquatic and terrestrial food chains and bio-magnify in predators due to consumption of contaminated prey. Small amounts of PCBs can also be found in soil surfaces, in surface water and plants.
Among the health effects caused by PCBs are skin rashes, disturbance in liver functions and the immune system, irritation of the respiratory tract, headaches, dizziness, memory loss, nervousness, fatigue, impotence and mutation.
The management of PCBs at the global level is through various conventions such as the Stockholm and Basel Conventions. The Stockholm Convention was adopted in Stockholm, Sweden 2001, and entered into force in May 2004. The Convention has the objective of protecting human health and the environment from Persistent Organic Pollutants (POPs). It recognizes the requirement for the development of National Action
Plans to identify, characterize and address the use of POPs. It is also an instrument used to strategize for identification of stockpiles of PCBs and articles in use and waste containing PCBs and contaminated sites (article 6). The phase out period for the PCBs according to the Stockholm convention is set at 2020, however the SADC region has an earlier deadline of 2015.
The Basel Convention on the other hand was adopted by member countries of the United Nations on the control of trans-boundary movement of hazardous waste and their disposal. It provides a number of obligations and guidelines in relation to the environmentally sound management of hazardous waste. The convention guides governments or organizations charged with the task of managing, destruction or decontamination of POPs generally and PCBs in particular with procedures that assist with the planning and selection of appropriate technologies that suit with the need for environmentally sound management principles and principles of sustainability.
In Zambia, the Environmental Management Act No.12 of 2011, with its subsidiary regulations, is the principal environmental law of the land. The Environmental Management (Licensing) Regulation of 2013, provide guidelines for the management of PCBs and other hazardous materials. The regulation provides for licensing of hazardous waste production, storage and disposal facilities.
Over 10,000 pieces of equipment were captured in the inventory, characterized and some randomly sampled and tested for PCBs. Concentration of PCBs containing equipment were found in Kariba (22 transformers containing over 14,000 litres of pure PCBs) and in Kitwe on the Copperbelt (with over 1,900 PCB filled capacitors weighing over 64,000kg).
