| 1. | No works shall take place in relation to any of the development hereby approved (except works required to secure compliance with this condition) until the following Contaminated Land reports (as applicable) are submitted to and approved in writing by the Local Planning Authority:
a) A Phase I (Desktop Study) Report documenting the history of this site, its surrounding area and the likelihood of contaminant/s, their type and extent incorporating a Site Conceptual Model.
b) A Phase II (Site Investigation) Report if the Phase I Report confirms the possibility of a significant risk to any sensitive receptors. This is an intrusive site investigation including factors such as chemical testing, quantitative risk assessment and a description of the site ground conditions. An updated Site Conceptual Model should be included showing all the potential pollutant linkages and an assessment of risk to identified receptors.
c) A Phase III (Risk Management Strategy) Report if the Phase II Report confirms the presence of a significant pollutant linkage requiring remediation. The report will comprise two parts:
Part A - Remediation Scheme which will be fully implemented before it is first occupied. Any variation to the scheme shall be agreed in writing to the Local Planning Authority in advance of works being undertaken. The Remediation Scheme is to include consideration and proposals to deal with situations where, during works on site, contamination is encountered which has not previously been identified. Any further contamination shall be fully assessed and an appropriate remediation scheme submitted to the Local Planning Authority for written approval.
Part B - Following completion of the remediation works a 'Validation Report' must be submitted demonstrating that the works have been carried out satisfactorily and remediation targets have been achieved.
d) If during development works any contamination should be encountered which was not previously identified and is derived from a different source and/or of a different type to those included in the contamination proposals, then revised contamination proposals shall be submitted to the LPA; and
e) If during development work, site contaminants are found in areas previously expected to be clean, then their remediation shall be carried out in line with the agreed contamination proposals.
For further guidance see the leaflet titled, 'Land Contamination and the Planning Process'.
Reason:-
Insufficient information has been supplied with the application to judge the risk arising from contamination. Submission of an assessment prior to commencement will ensure the safety of the occupants of the development hereby permitted and the public generally. |
