They came up with a post-decommissioning fund. Now, in my experience as an environmental engineer carrying out actual environmental remediations on some of New Zealand's most hazardous sites, sites where pesticides were manufactured, where timber treatment chemicals were used, and, during their use at a time even before I was born, when safety conditions and environmental best practice wasn't what it is now, there was soil contamination and water contamination. But when you go and you clean up a site and you meet the resource consent conditions or the consent conditions for the clean-up, then you get it signed off by the engineers and the scientists and local Government—and, in this case, of course, energy is regulated by the Ministry of Business, Innovation and Employment—and you get signed off. At that point, they say, "Thank you for decommissioning and decontaminating your site. Here is the certificate to say you've met your obligations. Here's your bond back. Here's a letter to say that we're satisfied with your environmental performance."
