Laos Addresses Use, Treatment, and Disposal of PCBs in Electric Transformers

On January 20, 2021, Laos published its Decision on the Management, Monitoring, Treatment, and Disposal of Polychlorinated Biphenyls (PCBs) in Transformers No. 5925/MONRE, which entered into force 15 days after its publication. The decision aims to provide guidelines on the management of PCBs used in electric transformers, and to reaffirm Laos’ international commitments under the Stockholm Convention on Persistent Organic Pollutants.

Background

The decision was developed by the Ministry of Natural Resources and Environment (MONRE). Under the local legal framework, the Law on Chemical Management (2016) places the MONRE in charge of monitoring and managing chemical waste in Laos. The Law on Environment Protection (2012) holds liable individuals and legal entities whose activities create poisonous, toxic, or dangerous waste, and directs local business operators producing such waste to store it and prevent any damage according to the relevant standards and regulations. However, the country’s laws and regulations have yet to provide these standards.

On the international stage, Laos is a contracting member of the Stockholm Convention on Persistent Organic Pollutants, having ratified the convention on June 28, 2006. Parties to the convention are required to eliminate the use of PCBs in existing equipment by 2025 and ensure environmentally sound waste management of them by 2028. Laos thus issued the National Implementation Plan under the Stockholm Convention in March 2016 to phase out the country’s use of PCBs. The National Implementation Plan under the Stockholm Convention had observed that Laos had had no specific law or regulation for managing equipment or waste containing PCBs, and identified some electric transformers as a source of waste containing PCBs.

Accordingly, the recent decision also provides that the local administration representing the MONRE in each province must cooperate with the administration representing the Ministry of Energy and Mines, Industry and Commerce, and other local administrations, state enterprises, and the private sector, to conduct a survey and an inventory of PCB waste in electric transformers. Thereafter, a report is to be sent to the Department of Management and Control of Pollution so that the information from the country can be centralized and submitted to the MONRE.

Affected Parties

The decision provides a regulatory framework for the following parties to manage PCBs in electric transformers:

individuals and legal entities in possession of electric transformers containing PCBs, or PCB waste related to these transformers;
operators transporting such electric transformers and PCB waste; and
service providers involved in the treatment and disposal of such electric transformers and waste.

Storage

Prior treatment and disposal of electric transformers with PCBs and PCBs wastes, individuals and legal entities in possession of these materials must store them in a safe location that prevents any environmental leakage. The site should be closed, with a concrete floor and a drainage system, and it should also be fenced in order to prevent any intrusion, with a signboard expressly prohibiting unauthorized entry. It must be located at least one kilometer away from communities, schools, hospitals, water sources, and sites of food production.

In addition, the decision requires these individuals and legal entities to report to the Department of Natural Resources and Environment, Department of Industry and Commerce, and Department of Energy and Mines, every six months. The containers in which such electric transformers and waste are kept must bear visible, legible, and durable labels and warnings in Lao and English, so that persons close by or transporting and storing the containers are aware of the toxicity of their contents.

According to the decision, which refers to the Law on Chemical Management (2016), electric transformers containing PCBs, and PCB waste, may be stored for a maximum of 90 days.

Transport

The transport of these electric transformers and PCB wastes to treatment and disposal facilities must also guarantee safety to health, life, assets, the environment, and society. A hazardous substance sign must also be affixed to the vehicle: a “danger toxic substance” warning, with a big red skull symbol placed at the front and rear, along with the two sides of the vehicles transporting the electric transformers and PCBs.

Incident Notification

If there is an “emergency event” (not further defined) or leakage, the individuals and legal entities identified above are responsible for any initial adverse impact and must find a solution. The village authority, Office of Public Security, along with the district, municipality, and city authorities, must be notified of the incident. In parallel, the Department of Natural Resources and Environment and other administration at the province level should be informed so that they can propose measures to control the incident.

If the “emergency event” involves a chemical leakage from the electric transformers or a leakage of the waste while it is being transported, the transporter must formally report the incident to the local administration. In addition, at the provincial level, the Department of Natural Resources and Environment and the Department of Industry and Commerce must be notified.

Treatment and Disposal

According to the decision, the treatment of PCB refers to decontamination or actions to decrease the level of concentration of PCB chemicals in the oil of electric transformers, such that it does not exceed the minimum tolerated international standard. The disposal process consists of destroying PCB chemicals by using technology or other chemicals. These processes must be conducted by authorized operators.

The facilities conducting these processes must be located sufficiently far from communities and watercourses and their location must be endorsed by the MONRE. Individuals and legal entities treating or disposing of PCB waste must be registered with the Ministry of Industry and Commerce and licensed for the relevant operation by the MONRE.

These service providers must also have an expert with experience in the treatment and disposal of PCB chemicals contained in electric transformers, and in the disposal of PCB waste; have a location certified for this type of activity; and have the appropriate equipment, material, vehicles, and technology.

Improper treatment or disposal can result in a temporary suspension or cancellation of the license to operate treatment and disposal services for the following circumstances:

The treatment and disposal processes use methods and techniques not compliant with scientific principles.
An operator conducting treatment or disposal uses equipment, material, or technology that is not appropriate for the treatment and the disposal, and causes pollution.
An operator does not implement safety measures to protect lives and assets during treatment or disposal process.
An operator does not have a technician or expert in the treatment and disposal field.

For a first-time offense, the Department of Natural Resources and Environment will submit a proposal to the Department of Industry and Commerce to suspend the infringing operator’s operator license, so that they can correct and bring their operations in line with the law and regulations; the decision does not provide a timeframe for this.

If the operator cannot correct its operations as required, the Department of Natural Resources and Environment will propose to the Department of Industry and Commerce that they cancel the license.

Conclusion

With this decision on PCBs in electric transformers, Laos continues to bring disparate elements of its legal system in line with international agreements and protocols, demonstrating concern not only for accepted global industry standards but also for health, safety, and the environment. While this decision is highly focused in nature—an important update for owners and handlers of PCB-containing electric transformers and the waste derived from them—it can also be taken as further indication of Laos’ intention to be an active and responsible member of the international community.

Healthcare in Cambodia: Crackdown on Illegal Advertising and Noncompliant Services

Cambodia’s Ministry of Health (MOH) continues to increase awareness among the public and private sector of the need for strict healthcare regulations and strict enforcement to advance the quality of the country’s healthcare sector. In April 2023, the MOH issued a notification letter reminding advertisers of health products that they need to obtain a permit before advertising their products in Cambodia. On October 12, 2023, the MOH issued two press releases on continued noncompliance in the healthcare sector. The two press releases address the illegal advertising of both healthcare products and private healthcare services. The releases also address unlicensed healthcare professionals and general noncompliance by private healthcare services. These releases indicate that the MOH, in cooperation with local authorities, will substantially increase its enforcement efforts across Cambodia. Since October 12, several private healthcare clinics have had their operations closed and licenses suspended or revoked, signaling the ministry’s intent to enforce the legal framework. Noncompliant Advertising of Health Products The first press release focuses on the continued illegal advertising of health products and the advertising of unregistered health products. Health products include modern medicines, traditional medicines, health supplements, medical devices, cosmetics, and other products that prevent or treat diseases. The release highlights that the MOH has noticed ongoing unauthorized and illegal advertising, commenting that these are often found online and on social media. The noncompliant advertising referenced in the release includes advertising of health products without the required advertising permit, advertising products that are not properly registered with the MOH, and advertising by unlicensed companies and individuals. The MOH also states in the release that some advertisements are using inappropriate and noncompliant content that is not based on medical science and exaggerates the qualities of the health products—specifically mentioning skin-whitening cosmetics. The ministry’s press release also informs the public of

Food Nutrition Labeling in Cambodia: What Are the Rules?

Cambodia’s Law on Food Safety came into force on June 8, 2022. This law has been widely regarded as a major legal development of the food safety framework in Cambodia, providing new rules, clarifying existing rules, and setting a clear framework for its implementation and enforcement. In addressing some of the key features of this new law shortly after it was passed in 2022, we remarked that we eagerly await implementing regulations. Since then, various regulations have been adopted, such as two regulations (Sub-Decree No. 13 and Prakas No. 80) on food surveillance, recalls, and seizure. These implementing rules are essential in ensuring that enforcement officers can remove noncompliant and unsafe foods from the market. Another key aspect of the Law on Food Safety is that it requires Khmer-language labeling on prepackaged food products. There has been a notable increase in the inclusion of Khmer labeling on food products in the market since June 2022, but noncompliance is still considerable, especially for imported foods. Further interesting labeling rules set by the Law on Food Safety include a requirement to provide nutrition information. This requirement has not yet been widely adopted, with many in the industry highlighting that the details of this labeling requirement are not clear. Indeed, the relevant article of the Law on Food Safety itself only sets the requirement for food products to bear nutrition labeling and does not spell out what detailed information should be provided or in what manner. However, a prakas (ministerial regulation) adopted months prior to the Law on Food Safety does set out clear guidance on nutrition labeling. As long as this earlier regulation is not replaced or abrogated, and as far as it does not conflict with later laws or regulations, it can be relied upon for guidance. What are the

Cambodia Sets Registration, Standardization, and Energy Efficiency Rules for Appliances

Cambodia has issued a set of regulations that aim to encourage greater energy efficiency from appliances marketed in the country. The regulations follow Cambodia’s adoption of its National Energy Efficiency Policy, which sets out the government’s energy efficiency targets and policies to reach them by 2030, including the ambitious national target of reducing the country’s total energy consumption by at least 19%. This set of regulations for appliances marketed in Cambodia is contained in Sub-Decree No. 254 on the Management and Improvement of Energy Efficiency of Electrical Appliances, dated August 11, 2023. This sub-decree sets out product registration and energy efficiency labeling requirements for electrical appliances marketed in Cambodia. It further provides that appliances should meet energy efficiency standards and all other mandatory standards that apply to electrical appliances. During the product registration process, the appliances are checked against such standards, and registration is only granted if the standards are met. The sub-decree identifies the Ministry of Mines and Energy as the main ministry responsible for the implementation of the sub-decree. To assist with the wide scope of regulations as set by the sub-decree, it further appoints assisting ministries that may implement and enforce only certain aspects. These effective implementation and enforcement mechanisms suggest that once the sub-decree’s 12-month implementation period has passed, there is likely to be a rather strict enforcement approach to the requirements. Key Features of the Sub-Decree Several mandatory standards have already been applied to most electrical appliances over the past years, but the required product registration process to check for compliance with those standards has not always been completed by those importing, distributing, or manufacturing electrical appliances in Cambodia. The new sub-decree clearly mandates a product registration requirement as a check to verify the applicable standards are met, and sets penalties for non-compliance. Penalties
