Call for intervenors ~ have your say on the Chalk River radioactive waste mound at the public hearings that start on May 31

Note: If you are seeing this page for the first time and the April 11 deadline has passed, feel free to write to the CNSC to tell them what you think, and copy your Member of Parliament.

On May 31st the final licensing hearing for giant Chalk River radioactive waste mound will begin. The Commission will hear interentions (10 minute presentations) from First Nations, NGOs, municipal representatives, citizens’ groups and others.

This will be the final opportunity for the public to comment on this flawed proposal that will endanger the Ottawa River when this mound leaks and disintegrates, which the proponent’s own studies show is inevitable. There are many good reasons to stop this dump. For a simple summary of six of the most compelling see this post.

You do not need to have any scientific or technical expertise to intervene. Your intervention/submission/letter can be short or more substantial. Some of the most effective interventions in past hearings have involved singing and/or strong visual images. You can present a slide show that could include a short video. Passionate pleas for common sense are good too! Let’s press the CNSC to uphold its mandate to protect the environment and current and future generations of Canadians.

Contact us if you would like more guidance than is contained in this post.
