You know Chuck, we do have several bids and several jobs I should say that have included extensive nuclear services work in the field that has resulted in shipment of waste to ourselves to process. The job of the Harvard review hospital for example, we, we did the remediation packs away ship with our, our facility in Richland, Washington, processed it and got rid of everything, we're full service cut out a lot of inefficiencies, it worked really well. Other projects we’ll typically do the remediation and the waste may or may not require treatment. In other words, if it doesn't require treatment, it can be shipped directly for disposal in a landfill. That's normally the largest volume of the waste we have that’s the case, but we're bidding on several jobs right now that does include some treatment into processing. If there's any way we can ship something like large components, so our facilities and do the dismantlement off site, we'll do that, It doesn't always afford that an opportunity. But to answer your question, most of the time, it's one of the other uses of doing a waste treatment, or we're doing the services. And in the field, we're doing the services, the integral services types of jobs, you're typically shipping the waste direct to disposal, and it doesn't have the opportunity for the treatment, overall. But what we do, what we do is when we're the real discriminator comes in for our company, because we have the waste management people, the professionals engineers, that we put on the services projects that that are able to manage the waste and minimize treatment as necessary, and the packet and optimize the packaging, so you can go directly to disposal and save money.
