I thank the noble Baroness, Lady Bennett, for tabling her amendments, so ably introduced by the noble Baroness, Lady Jones of Moulsecoomb. I welcome her raising the important issue of contaminated land in this Committee. As always, the noble Baroness, Lady Jones, made some very powerful points—as did the noble Baronesses, Lady Hayman and Lady Pinnock—on the need for speeding up the process of decontamination. I believe the ambition to bring a version of Zane’s law on to the statute book is well intentioned but I consider that the policy intent behind these proposals is already met by existing legislation and statutory guidance.
The noble Baroness, Lady Jones, is right that Section 143 was repealed, but it was replaced by Part IIA of the Environmental Protection Act 1990, which provides a framework for identifying contaminated land in England and allocating responsibility for its remediation. It provides a legal definition of contaminated land and lays out the responsibilities of local authorities and the Environment Agency for dealing with it. These responsibilities include a requirement for local authorities to inspect their area to identify actively land that may be contaminated, to investigate and remedy contaminated land and to maintain a public register of information relating to contaminated land. This includes contamination from non-operational historic landfill sites and is regulated by local authorities. Further, Part C of the building regulations requires reasonable precautions to be taken by developers to avoid any risk to health and safety caused by contaminants in the ground where they are carrying out building work.
Lastly, assessment of contaminated land risk currently focuses on the impact of contaminated land on human health and the environment. Shifting focus on to buildings and building safety may dilute the aims of the existing framework. Given that this existing framework is already embedded into legislation and guidance, the proposed amendments regarding contaminated land would create unnecessary duplication and could cause confusion for local authorities. Therefore, while I appreciate the concerns of the noble Baroness, I ask her to withdraw her amendment.
