Offer: WE LOOK AFTER THE ENVIRONMENT
Iberdrola is committed to giving you advice on energy and environmental management for your business.
Certain equipment found in electrical installations, such as electrical transformers or capacitor banks, may contain compounds considered hazardous (PCB, polychlorinated biphenyls or polychlorinated terphenyls, known commercially as “pyralene”) that need to be treated and disposed of.
The Iberdrola PCB Disposal Service is a tailored solution for disposing of pyralene or PCB found in your company's equipment in accordance with current legislation.
Our service includes:
- Free initial diagnosis.
- Chemical analysis of equipment that may contain PCB using a Government-authorised company.
- Disposal and elimination of equipment containing PCB, using a Government-authorised company.
- Adaptation of the equipment and installations using the safest and most efficient procedures.
Frequently Asked Questions: What is pyralene or PCB?
Polychlorobiphenyl (PCB), commonly known as pyralene, is agroup of substances considered to be hazardous waste, which can be found in a significant percentage of equipment such as transformers or capacitor banks, among others. It has traditionally been used in industry, especially in electrical insulation and for cooling of certain types of electrical transformers.
Frequently Asked Questions: What are the hazards posed by PCB?
Following confirmation by the scientific community in the 1960s of their low biodegradability and capacity for bioacummulation in fatty tissues, the potential risk to human health (PCB has been catalogued as carcinogenic) and the environment was made clear, and a process for regulating and banning its use began.
Frequently Asked Questions: What are the obligations on companies?
In accordance with Royal Decree 228/2006 [PDF], Footnote (*) dated 24 February, which amends Royal Decree 1378/1999, dated 27 August, and lays down measures for the disposal and management of polychlorobiphenyls, polychloroterphenyls and the equipment in which they are found, the owners of PCB and of equipment that contains or may contain PCB are under the following obligations:
- Check and certifythe existence of PCB in dielelectric oils or other liquids, by taking samples and conducting chemical analyses, which will be entrusted to Authorised Control Bodies or Government Affiliations in the field of the environment, whenever necessary. These analyses must be completed before 31 December 2008, in accordance with the schedule envisaged in legislation.
- Hand over the PCB, used PCB and equipment containing PCB to an authorised waste manager when this needs to be decontaminated or eliminated.
- Eliminate or decontaminate leaking equipment that contains or might contain PCB as soon as possible.
- Eliminate any equipment that has reached the end of its service life and might contain PCB, proceeding as follows:
- Option 1: Conducting a chemical analysis:
- If the PCB concentration is equal to or more than 50 ppm, hand it over to an authorised PCB manager for disposal.
- If the PCB concentration is less than 50 ppm, it must be managed in accordance with used industrial oil legislation.
- Option 2: Without conducting a chemical analysis:
- In this case, the owner must hand it over to an authorised manager so that it is eliminated once and for all as equipment containing PCB.
- Option 1: Conducting a chemical analysis:
- Decontaminate or eliminate electrical transformers with a PCB concentration of more than 500 ppm, other types of equipment with a PCB concentration of equal to or more than 50 ppm and contained PCB before 1 January 2011.
- Draw up an inventory of equipment containing PCB.
- On an annual basis, declare the inventoried PCB equipment, the plans to decontaminate or eliminate them and identified equipment that has already been decontaminated or eliminated to the regional governments, providing the necessary supporting documentation.
- Label and mark all owned equipment that is inventoried.
Frequently Asked Questions: When is the deadline to eliminate it?
PERIODO PARA LA ELIMINACIÓN DE APARATOS FABRICADOS CON FLUIDOS DE PCB FECHA DE FABRICACIÓN ELIMINACIÓN FECHA DE FABRICACIÓN DESCONOCIDA Antes del 1-1-2007 FABRICACIÓN ANTERIOR A 1965 Antes del 1-1-2007 FABRICACIÓN ENTRE 1965 Y 1969, AMBOS INCLUSIVE Antes del 1-1-2008 FABRICACIÓN ENTRE 1970Y 1974, AMBOS INCLUSIVE Antes del 1-1-2009 FABRICACIÓN ENTRE 1975 Y 1980, AMBOS INCLUSIVE Antes del 1-1-2010 FABRICACIÓN POSTERIOR A 1980 Antes del 1-1-2011
Frequently Asked Questions: ELIMINATION OF PCB-CONTAMINATED EQUIPMENT
The equipment must be decontaminated or eliminated in accordance with the following years and minimum percentages, in relation to the total amount in weight (solid plus liquid) that it contains at the start of each year:
PORCENTAJES ANUALES DE ELIMINACIÓN DE APARATOS CONTAMINADOS POR PCB AÑO PORCENTAJE AÑO 2006 20% AÑO 2007 25% AÑO 2008 33% AÑO 2009 50% AÑO 2010 100%
This obligation is legally binding on installation owners, and if they keep such substances after the aforementioned dates it will be a cause for penalty.
Frequently Asked Questions: What are the problems involved in eliminating it?
The final stage of the pyralene elimination process must take place outside national soil. Apart from delaying the process, this points towards possible market saturation and the consequent increase in cost, since the aforementioned deadline applies to all EU countries.
Iberdrola therefore recommends that you start the process to eliminate this substance as soon as possible.
