A land contamination assessment should include an extended assessment of contamination in line with Planning Policy Statement 23: Planning and Pollution Control (November 2004). Sufficient information should be required to determine the existence or otherwise of contamination, its nature and the risks it may pose and whether these can be satisfactorily reduced to an acceptable level. Where contamination is known or suspected or the proposed use would be particularly vulnerable, the applicant should provide such information with the application as is necessary to determine whether the proposed development can proceed.
