Well, I thank Hefin David for that question. The regulation and monitoring of anaerobic digesters on farms is the responsibility, as you say, of Natural Resources Wales. Under the environmental permitting regime, farms can register an exemption, provided they meet set criteria and limits, for example the volume of materials that they can treat. But following recent incidents, not just the one that you referred to, Hefin, we’ve asked NRW to review the regulations and we’ll be working very closely with them on this. And the evidence today will, I’m sure, be taken into account.
