Planning document information

Description 

A contamination risk assessment, is a report that provides details of previous uses and a risk assessment of the proposed development site to make sure that the land is not contaminated. 

The report, which may be known as a Phase 1 includes a desk study, a site walkover and an initial risk assessment 

Guidance 

We recommended that you speak to a qualified individual or certified company to carry out this assessment. 

You can also talk to our Environmental Health team for more help and advice 

The report you submit should include an executive summary and be clear, easy to read and jargon free.
