Hi all, I have a site that has come through the planning process where the applicant wants to build a new property approx 100m from an infilled chalk pit. The applicant states the pit was infilled with inert clay material, however we have no way of knowing this for sure. In order to give us more weight in our argument I was just wondering if anyone has any examples of where someone has said a pit or quarry has been infilled with apparently inert material only for a site investigation to show that it is giving off elevated gas concentrations? I have a feeling there was a part IIA site from a couple of years ago where there was a similar situation??
