Thank you for that answer. TAN 21, as you've just outlined, covers waste disposal, but, unlike opencast, where, since 2009, coal mines have to be built more than 500m away from homes, there does not appear to be a rule on distance of incinerators from houses. I've an incinerator planned for the Llansamlet area of Swansea that is close to both houses and a school. Will the Welsh Government consider a distance from houses and schools for the building of incinerators and amend TAN 21 accordingly?
