THE environment-advocate group, EcoWaste Coalition urged the public to support the effort of the Department of Environment and Natural Resources (DENR) to get rid of a highly toxic class of obsolete industrial chemicals called polychlorinated biphenyls (PCBs) used in old electric transformers and capacitors.

The group through its chemical safety campaigner, Thony Dizon made an appeal coinciding with the 18th year of the promulgation of the Chemical Control Order (CCO) for PCBs on Feb.16, 2004.

Dizon stressed that all stakeholders must rally behind the DENR to achieve the country’s “PCB-free” target by 2025.

The said CCO is the principal regulatory enforcement framework to comply with the country’s obligations on PCBs under the Stockholm Convention on Persistent Organic Pollutants (POPs) to which the Philippines is a party. This major multilateral chemical treaty has set a 2025 target to phase out the use of PCBs in equipment, and a 2028 target to eliminate PCBs.

The DENR had earlier banned the importation of PCB or PCB-containing equipment since March 19, 2004, pursuant to the CCO.

“With 2025 not too far away, we urge all concerned sectors, especially electric utilities and cooperatives and other PCB owners, to remain on track and complete the phase-out of PCB use in equipment and to ensure the non-incineration destruction of our country’s PCB stockpiles. Let us rally behind the government’s action to make PCB pollution history,” Dizon said.

At the last Conference of Parties (COP9) held in 2019, a report on the global progress in eliminating PCBs emphasized the need for parties to ramp up efforts to eradicate PCB use and ensure the environmentally sound management of PCB wastes.

A supplemental Memorandum Circular issued by the Environmental Management Bureau (EMB) on Jan. 30, 2015 states that “no additional PCB-equipment, PCB-contaminated equipment, non-PCB equipment shall be used.”

The said circular further stated that the “remaining PCB equipment, PCB-contaminated equipment, non-PCB equipment and PCB wastes that were not disposed of after March 19, 2014 shall be subject to phase-out and environmentally sound treatment and disposal at the earliest time possible.”

PCBs remain intact for long periods of time, travel long distances, accumulate in fatty tissue of humans and wildlife, and bio-concentrate in the food chain.

PCBs can enter the body by eating or drinking contaminated food and water, inhalation, or by skin contact. PCBs can interfere with hormones and their actions in the body, suppress the immune system, cause reproductive failure, and increase the risk of cancer.

As mentioned in the country’s National Implementation Plan (NIP) for the Stockholm Convention, “the most vulnerable sector exposed to the hazards of PCBs are those working in electric utilities with transformers filled or contaminated with PCB oil,” noting that everyone, including wildlife, can be exposed to PCBs.

The updated inventory of the country’s stockpile of PCBs and their environmentally sound treatment and disposal remains a top priority for the government as the 2025 target for a “PCB-free” Philippines approaches.
