Land Contamination Assessment
LFA can undertake a range of land contamination assessments from preliminary site history reviews through to the implementation of remediation and validation of a site. Our staff are experienced in the collection and analysis of detailed analytical data. LFA takes a practical approach to each project and undertakes critical review throughout the course of each project to ensure the most cost effective outcome is achieved. Types of assessments undertaken by LFA include:
Preliminary Land Contamination Assessment Reporting: Site history review, field sampling and associated reporting for single dwelling lots and future subdivisions;
Detailed Site Investigations: required in instances where the extent and concentration of contaminants needs to be identified and delineated
Remedial Action Plans (RAP): developed to facilitate the remediation of contamination at a site
Validation Reporting: sampling and reporting post remediation to allow a site to be declared fit for a prescribed use
Site investigation and reporting relating to waste classification
SEPP 55 Assessment
Land contamination assessments for local developments are generally triggered due to the change of use of a site to a more ‘sensitive land use’, such as in the case of where a residential dwelling is proposed to be built on land that was previously used for agriculture.
State Environmental Planning Policy No. 55 – Remediation of Land (SEPP 55) is the planning instrument that guides local councils in relation to the carrying out of development on land within their LGA. In the case of a Development Application (DA), a council will not consent to the carrying out of any development on land unless it has considered whether the land is contaminated (in accordance with cl. 7 of SEPP 55). If the land is found to support contamination council needs to be satisfied that either the land can be developed and/or suitably remediated.
The process of assessing, remediating and validating a site is described in detail in SEPP 55 and a number of associated guiding documents.
