Thank you very much for that question.
This amount of money, the $22.6 million, is to address our high-risk contaminated sites. When you're talking about risk assessment, yes, this one really is focused on human health and the environment.
As I mentioned, we have a large inventory of sites, a lot of them are former airport sites, or port sites, or existing airport sites. We have a three-year investment plan for all of our sites, including our contaminated sites. We bundle them into two envelopes. The federal contaminated sites, which are the high-risk to health and the environment, get funded from this envelope, and the other ones get funded from other funds within the department once we have those funds.
We do assessments at every single one of them. The assessments are to identify the contaminants. As part of that assessment, we develop what is called the remediation plan, which is how we are going to address decontaminating the site and undertake that work. Every year we're funding a variety of sites across the country. This funding is really going to help us make a good dent in our highest-risk sites in terms of making sure we are addressing those that are at the highest risk in terms of human health, such as if they're getting seepage into the water or the effects are right on humans or into the environment.
Because we have such a large number of sites, we cannot do them all in one year. We do have this investment plan that basically allows us to chip away at them. Once the sites are cleaned, we will normally transfer them to municipalities or local interests that are interested in the sites.
