I must apologise to the hon. Lady. A large number of points have been made during this three-hour debate and I was not, I am afraid, going to attempt to answer each of them today. I will pick them up and, if I may, write to colleagues whose points I have not had time to consider.
The hon. Lady asked about pollution. During construction and drilling of the well, the operator will monitor emissions at the site, and that will have to be a permanent feature of operations should the activity proceed to commercial development. The Environment Agency has also recently published research to understand
how emissions from a well can affect air quality, how they can be monitored and what controls are available. If I can give her any further information on that, I certainly will.
My hon. Friend the Member for Lancaster and Fleetwood (Eric Ollerenshaw) had concerns about borehole users and whether there would be a reduction in their supplies. It is likely that most operations will use public water supplies so far as practicable, because that is the most likely way to reduce truck movements to and from sites. However, where operators want to extract water directly from aquifers, again, they will need a permit from the Environment Agency that will not be given if the quantities that they require are not sustainable.
The hon. Member for Brighton, Pavilion made a very large number of points, and I am afraid that I may have to reply to her in writing about some of them. She specifically asked me about the disclosure of the use of chemicals. The answer to her question is yes, the Environment Agency will require disclosure of all substances proposed for injection into groundwater that might affect the water, and it will only approve the use of those chemicals if they are assessed as harmless in that context.
