Rejecting "Safe Levels" for Hazardous Wastes
Don't Sacrifice Principles of Precaution, Good Science and Sovereignty for False Clarity
At the upcoming meeting of the Expert Working Group on the Review of Annexes to be held in Geneva from December 5-7, 2022, Parties present will be pressed to decide on a proposal from the European Union to adopt for the first time, threshold level values for toxicity, ecotoxicity, etc. These are proposed to be drawn from the UN Global Harmonized System (GHS) of Classification and Labeling of Chemicals and used as hazard thresholds for certain of the H entries in Annex III. Thus, if a waste falls below these values it will be deemed non-hazardous, and Parties would be obligated to accept this determination.

While this might sound like a way to bring the much sought after "legal clarity" to implementation of the Convention, it is in fact:
  • unscientific
  • non-precautionary
  • prejudicial to developing countries
  • a violation of sovereign right to enact stronger controls
  • an incentive for waste dilution to avoid prosecution
  • institutionalized reliance on outdated toxicology, and
  • ignorant of on-the-ground realities of waste management.
In their comments already, the United States, Italy, Hazardous Waste Europe, El Salvador, and Canada have expressed reservations to this approach. Indeed, for a variety of reasons it is a very bad idea. Below, the International Pollutants Elimination Network and the Basel Action Network highlight just some of these concerns. See BAN comments on the EWG Review of Annexes for more detail.
Unscientific
Wastes are in fact most often a complex mixture of potentially thousands of toxic chemicals. A recent scientific study identified more than 2,400 chemicals of concern used in plastics[1] alone. It is almost impossible for importers or exporters to know the concentrations of such chemicals. Many of these chemicals are non-threshold toxicants that can cause significant harm even at very low concentrations, so no safe level can be established. These include endocrine disrupting chemicals, carcinogens, and chemicals harming neurodevelopment.

A wealth of scientific evidence has been generated that shows that mixtures of hazardous chemicals generally have a higher toxicity than the individual chemicals themselves. Even in mixtures where all the toxic chemicals are present at levels that are considered “safe” in traditional risk assessment, the mixture toxicity can be significant[2]. This is due to the combined impacts from each chemical in the mixture, leading to harm to human health and the environment.

Thus, the adoption of the GHS levels for individual chemicals would make it highly likely that more hazardous waste would be exported under the false assumption of being safe. These thresholds are far too generic and are already outdated, with many having been adopted in 2003. The GHS also lacks description and considerations for important toxic impacts under H11 (toxic), such as endocrine disruption.
Since the beginning of the sad history of international waste trade, developing countries are at a huge disadvantage to manage and test the complex wastes arriving on their shores. These wastes that sparked the adoption of the Basel Convention were a mixture of some of the most hazardous man-made substances known, including dioxins, all derived from the Italian chemical industry.

Prejudicial to Developing Countries

The Basel Convention was created primarily to protect developing countries from the exploitation caused by waste traders who were externalizing costs and harm to them from developed countries. Thus, it is ironic and contradictory to utilize analytical, numeric concentration levels that will be prohibitively costly to implement and enforce. Developing countries will be disproportionately burdened due to limited resources to implement the very expensive analytical lab work that will be required. Analytical testing teams, equipped with gas chromatography-mass spectrometric analysis, are extremely expensive, and not many police and labs in the developing world can do this technique routinely for the vast number of waste shipments currently arriving at their ports. Even if this analysis is required of the traders prior to export, a competent authority will still need to be able to independently corroborate the claims.

It is unreasonable to expect a small government with limited staff and budget to defend its assertion that a waste should be controlled as a hazardous waste and risk being challenged or sued by a company with far greater resources for lawyers and laboratories with a very different, self-serving idea. Legal battles favor rich plaintiffs and not developing country defendants. The victim country in such a case may never get accountability for illegal traffic and risks being victimized twice: first from the chemical assault, and second from the attempt to prove a legal basis for prosecution and accountability at great cost.
 
Violation of Sovereign Right to Adopt Stronger Controls

In Article 4, paragraph 11 of the Convention, it is asserted that nothing shall prevent a Party from imposing additional requirements to protect human health and the environment.  Being shackled to "safe levels" of wastes denies that right of Parties to utilize a "precautionary" or even a "risk-based" approach to determining whether they wish to export or import a waste of concern. It is a fundamental contradiction with the Convention's established right to assert stronger requirements, even on a case-by-case basis This is the right of any Party and the job and in fact the responsibility of a Competent Authority and their staff. This comes ahead of dilution in the original bulleted list on p. 1 - perhaps re order the list to keep them in the same order?

Dilution Cannot be an Encouraged Solution

One of the perverse effects of setting concentration thresholds, below which chemical wastes will be deemed non-hazardous and therefore outside of the scope of the Convention, would be to create an incentive to dilute wastes to a point where they miraculously could be deemed "non-hazardous". In some jurisdictions such dilution is illegal, but enforcement of such a prohibition is near impossible. Operations can easily hide dilution as being part of process. As noted earlier, concentration levels are not a good indicator of harm. When the issue of ship recycling became of great concern in the Convention, the Parties resoundingly deemed that even when the toxic materials in a ship were vastly outnumbered by the volume of non-toxic steel, this did not render the ships non-hazardous and free to export outside of the Convention's scope.

By only being concerned about concentration levels and allowing such levels to determine whether we should subject materials to control under the Convention, we will in fact encourage dilution as a false solution to pollution.
