Erection of a Dwelling Adjacent to a Limestone Quarry, Stainton, Rotherham
Case Study Reference: 11-05-02
Planning Authority: Metropolitan Borough of Doncaster
Planning Reference: 10/00497/FUL
A desk study report was prepared by others to discharge the contaminated land planning condition for the site. This report was submitted and a number of issues were raised in regards to the content of the report. At the time of being commissioned the dwelling had been erected and gas protection measures had been incorporated into the building design.
Demeter Environmental Ltd were commissioned to resolve the issues relating to the desk study report and agree a scope of the Phase II intrusive works.
Once the scope of the intrusive works had been agreed a number of dynamic sampling boreholes were sunk across the site with gas monitoring wells installed in three of the boreholes.
The site investigation identified elevated levels of benzo(a)pyrene in site soils which had the potential to impact on human health, elevated levels of carbon dioxide and a risk to water mains.
The sufficiency of the gas protection measures were assessed and it was concluded that the gas protection measures installed were sufficient, as part of the validation monitoring of confined within the dwelling was undertaken to demonstrate ground gases were not accumulating in the dwelling.
The validation of the remediation was undertaken in 2011 and it was demonstrated that the site had been suitably remediated and the site was suitable for use.
