I have been asked to reply.
I have placed a copy of Planning Guidance (Wales), Technical Advice Note (Wales) 3, Simplified Planning Zones—November 1996 in the House Library.
Planning policy in Wales is, of course, devolved to the Welsh Assembly Government. “Planning Policy Wales: March 2002” sets out the land use planning policies of the Assembly Government, which is supplemented by a series of technical Advice Notes (TANs). Copies of these can be obtained from the Assembly website at:
