Dr. Brian Donlon:

With regard to the Deputy's question about chemical free fracking products, task 6 of project B explicitly asked the consultants to look at this and what is going on worldwide. There are reports that members may have seen in which people say they can do it chemical-free. This is part one of the tasks they have to do. Another task is on the flowback fluid and looking at treatment and disposal methods and best practice; that is task 7 of project B. Therefore, the two points raised about chemicals and flowback will be addressed in the project.
