Environmental Site Assessments
Environmental Site Assessments
PHASE I AND II ENVIRONMENTAL SITE ASSESSMENTS
Environmental Site Assessments conducts Site Investigations in line with AS4482.1-2005. Parts of AS4482.1-2005 are reproduced below. These investigations are similar to Phase I and II Environmental Site Assessments.
PRELIMINARY SITE INVESTIGATIONS
The Preliminary Site Investigation is undertaken to ascertain what contaminants (if any) are present on a site. If the results of the Preliminary Site Investigation indicate that contamination is present or likely to be present, it should be followed by a detailed site investigation.
The process of site investigation and assessment is as follows:
(i) Preliminary study – including site history information collection.
(ii) Site inspection with or without sampling.
(iii) Preliminary site investigation report.
DETAILED SITE INVESTIGATION
The objectives of the detailed site investigation are to —
(a) assess contamination status
(b) establish the lateral and vertical distribution of contamination (c) identify, if possible, the source(s) of on and off site contamination.
A detailed site investigation may take several episodes of site assessment as further evidence of impacts is obtained.
The detailed site investigation will contain the following:
(a) A sampling strategy to test the conclusions of the preliminary site investigation.
NOTE: No sampling plan, however exhaustive, can completely eliminate the possibility that contaminants are present on a site. A satisfactory sampling plan is one which has an acceptable probability of detecting the presence of contaminants.
(b) Reporting on the methodology, basis of the works conducted, site observations,
sampling and analytical procedures, data collected and interpretation of the data.
(c) Conclusions of the investigation.
EPA VICTORIA SITE ASSESSMENTS
In February 2012 the Environment Protection Authority Victoria (EPA) released a series of documents known as the “Industrial Waste Fact Sheets”. In a statement about the new fact sheets the EPA said:
“The EPA can confirm the Industrial Waste guidance is now available on our publications database and ready to be used. Over the next six months EPA will be conducting follow up work to ensure industry understands what these documents mean, and are using this guidance. They will also be used by our environment protection field officers when they are conducting site visits and compliance checks of your businesses.”
THE “INDUSTRIAL WASTE FACT SHEET” PUBLICATION 1437 STATES:
“Land development and construction projects that require the excavation of soils should undertake a SITE ASSESSMENT. It is the responsibility of the person who is in occupational control of the site or the portion of the site from where the soil is excavated to ensure that it is managed according to the EPA requirements and that any waste is sent to an appropriate facility.”
RECOMMENDED METHOD FOR SITE ASSESSMENT (Taken from “Industrial Waste Fact Sheet” Publication 1437)
“1. Consider site use – The first thing to do when undertaking the SITE ASSESSMENT is to research a site’s current and previous land uses.
2. Inspect the site – Physically inspect the site. If the soil smells or is discoloured, there is evidence of industrial waste such as bricks and concrete, or you think the area could be contaminated for any other reason you should treat the area as potentially contaminated and take some samples for analysis. In most cases, specialist advice will be required to assist with taking soil samples and interpreting the test results.
3. Get professional advice – If the previous steps cannot determine the types of waste on site, you may need to get advice from a suitably qualified environmental consultant. ”
Environmental Site Assessments can perform this Site Assessment for you and produce a report that categorises soil and fill for off-site disposal. If sampling is required, Environmental Site Assessments can do it. Call us now for a free, no-obligation quote.
