Eric Friebel - Assessment of Petroleum Hydrocarbons HSLs, ESLs, Management Limits
The presentation focuses on the Assessment of Petroleum Hydrocarbons and the HSLs. It provides an overview how the NEPM has incorporated the HSLs and how they link together with the NEPM schedules. The conceptual site models used to define the screening criteria are presented along with a discussion on petroleum composition, carbon fraction ranges, soil descriptions and biodegradation. The presentation goes on to focus on the application of HSLs, and will step the viewer through the checklist outlined in the CRC CARE Technical Report 10: Applications Document, and provides advice on how to apply the screening levels, and different
considerations you may need to make, when assessing a site.
An overview of the ESLs and Management limits that have been included in the amended NEPM is also provided.

The Cooperative Research Centre for Contamination
Assessment and Remediation of the Environment (CRC CARE), in partnership with
participating jurisdictions, coordinated a national workshop series in May 2013
to provide regulators, site assessors, consultants, environmental auditors,
landowners, developers and industry practitioners with an opportunity to come together
and gain an understanding of the changes, new elements, and implementation of
the Assessment of Site Contamination NEPM amendment.
Members of the NEPM Variation team, along with
technical experts involved in developing guidance for inclusion in the amended
NEPM Schedules, presented the changes and identified new aspects in comparison
with the 1999 NEPM.
In response to feedback from industry and
regulators, which included requests to access the workshop materials and
information following the conclusion of the workshop series, CRC CARE has made
the workshop and presentation materials available on DVD. The enclosed set of
DVDs – containing the recorded presentations and audio from a live workshop – will be of
relevance to all regulators and practitioners dealing with the assessment of
