What happens at the site after the disposal activity is finished?
Once disposal activity is complete, what happens at the site depends on the quantity and type of material disposed of as well as the site’s environmental conditions. Before disposal activties, the permit review sought to predict of the fate of the material disposed of at the site based on the application’s data. This prediction is called an Impact Hypothesis. Selected sites are monitored each year to measure their environmental conditions and verify Impact Hypotheses. The results of these monitoring activities are used in future permit reviews to guide decision making. Details can be found in the Monitoring section.
