Obviously, we follow provincial government requirements for air monitoring in a region. That's mainly directed by operating approval requirements under the Environmental Protection and Enhancement Act, so we have to follow those.
We also are able to go above and beyond that, so we do special monitoring projects. Right now, we're starting a volatile organic compounds speciation project. That is not mandated by anyone. Our organization has received funding and is able to do it. We're also starting a particulate matter speciation project. All these things are over and above what is required by government.
