My Lords, I refer to my entry in the register. Amendment 372ZA seeks to amend the definition “environmental protection” to include specific reference to the protection of chalk streams. It was so eloquently moved by my noble friend Lord Trenchard, and I pay tribute to his and other noble Lords’ passion on this issue. I assure them that I would not stand at this Dispatch Box and in any way jeopardise the future recovery of our chalk streams. I was in one last weekend and I will be in one again this weekend, as the mayfly start to hatch.
Mention was made of the catchment-based approach— CaBA—which is a wonderful piece of partnership working, so ably led by Charles Rangeley-Wilson. I was fortunate enough to visit him in Norfolk, to see where he has reconnected with the valley bottom or river bottom chalk streams that were previously canalised for water meadows, sometimes hundreds of years ago. There are remarkable benefits, which we measure rather technically in the water framework directive, but the key indicators, such as ranunculus and fish populations, can be massively enhanced by many measures that he and others carry out. The work was led in this House by Lord Chidgey and, of course, in Hertfordshire by my right honourable friend Sir Oliver Heald, whom I met just a couple of weeks ago to talk about this.
There is undoubtedly some good news about chalk streams. The Mimram, which I visited in the past and which suffered from massively low flow, has seen some improvement, but there is still huge pressure on these remarkable places. I am on record talking about them as our country’s equivalent of the rainforests: these areas are, in large part, particular to England—85% of them are here—and we want to see them thrive. Some excellent points have been made.
This Government are committed to protecting chalk streams, which we defined as priority sites in the Storm Overflows Discharge Reduction Plan, with a target of a 75% reduction in harmful sewage spills by 2035. In our Plan for Water, the Government also committed to reviewing the impact on chalk streams of private sewerage systems—my noble friend Lord Caithness made this point well. The pressures on them are from sewage outflows and inadequate sewage-treatment plants, farming and run-off, and serious problems due to misconnections and private sewerage systems that are not functioning properly.
I say to my noble friend Lord Lucas that we will certainly address the Lottbridge Sewer—how on earth it got that name I do not know—and make sure that it
is part of our consideration of chalk streams. To the noble Baroness, Lady Jones, I say: the riverfly project of which she is part is one of the great examples of citizen science. It sees an enormous number of people assisting the regulator—the Environment Agency—in identifying when a problem occurs, so that it can then step in.
My noble friend Lord Caithness mentioned my visit to Marlborough in 2010, just after I became a Minister. I stood in a riverbed that was dry because water was being extracted from the Kennet and pumped out of the catchment to provide water for the people of Swindon. They needed water, but it should not have come out of the catchment. This really damaged a very special SPA and SSSI, but I am delighted that, through measures that the Government drove through our abstraction incentive mechanism, Thames Water then delivered water from the same catchment—the Thames—rather than the Kennet. The Kennet is now in a better, although not perfect, state. There are now huge opportunities, through private sector green finance initiatives and habitat restoration—driven by government actions, through ELMS and our Plan for Water—for chalk streams’ amazing natural environments to be restored, so that we can show the world that we lead the way on river restoration.
I certainly share my noble friend Lord Trenchard’s concern for the protection of chalk streams. I stress that the definition of “environmental protection”, for the purposes of the environmental outcomes report, has been drafted to ensure that the Secretary of State is capable of setting outcomes across the breadth of environmental concerns, very much including chalk streams.

Many specific aspects of the environment will need to be considered under this new system and it is crucial that our passion for chalk streams, which we are debating now, does not get lost in the fact that we are trying to create some special protections. These aspects of the environment, which will need to be considered under this new system, will need to be included, be they chalk streams or other important environmental matters. Given the need to capture the environment as a whole in these provisions, I hope that the noble Viscount will accept that it would not be appropriate to draw out granular considerations in this definition. As noble Lords will be aware, the Bill places a duty on the Secretary of State to undertake further public consultation when setting outcomes, and these will be brought back to the House for consideration under the affirmative procedure.
Therefore, with these assurances about the scope of the definitions and the opportunity for further scrutiny of outcomes, I hope that the noble Viscount will feel able to withdraw his amendment, but with the absolutely clear commitment from me that further conversations will be had, with him and others, about chalk-stream restoration and how we can better make sure that this continues to be a priority.
