My hon. Friend raises an important issue, and I understand that it has been rumbling on for quite a few years in Hertfordshire. It is for local authorities to develop their mineral and waste plans and then to consider subsequent applications. At all stages, the local authority is required to give consideration to the environmental effects of activities on residents. Any minerals and waste plan will be supported by a strategic environmental assessment, which will have regard to site allocations and activities, and any planning application should be supported by an environmental impact assessment. However, I suggest to my hon. Friend that she apply for an Adjournment debate, because this is exactly the sort of issue that is well highlighted in Adjournment debates.
