Share this post

ESC conducted a Portfolio HSE Due Diligence Assessment in 2019 involving 20 oil terminals and distribution depots and over 250 retail stations across the country.

About the Project

ESC completed a multi-site due diligence program for client who intended to acquire a portfolio of about 20 oil terminals and depots and over 250 retail stations located across Queensland, New South Wales, Western Australia and the Northern Territory.

Our Approach

The assessment was carried based on the ASTM E1527-13 Standard Practice for Environmental Site Assessment: Phase I Environmental Site Assessment, an international standard adapted for use in Australia.  

The assessment included “Remote Sensing” of operations using publicly available data and industry contacts to focus our review and review of a data room plus conference calls with the seller and site visits of a selection of assets in Brisbane and its vicinity. This included location and setting, site features and history, description of activities, tank storage, HSE policies, management and compliance systems, regulatory relations, risk management and audits, air, noise, odour, water, wastewater and solid waste management, fire protection, safety and security, site contamination, land ownership, asset integrity assessment, asset design, HSE claims, HSE and financial planning.


Recommendations were made for mitigation of potential liabilities by contractual protection and for issues which could impact transition to new ownership.

    Client Testimonials

    ESC thinks out of the box. They can come up with conventional solutions. But they are better in providing a solution fit for the company - one that feeds your organization. 

    ESC is focused on helping us solve our problem. Even if it means sometimes going out of the scope of what was originally agreed upon. So as a client, I can focus all my efforts on solving the problem.

    Head of Technical, Chemical Specialties

    We had no experience at first in dealing with Safety Cases and dealing with authority. When we have an issue, we ask ESC. Just one look at it, ESC already knows what to do. They  advise us accordingly and professionally and tell us what to do what to follow and to know. Our partnership with them produced good results.

    I do appreciate the times when ESC was there to help with an open channel and service-oriented communication. Ease of communication is what separates ESC from other consultants.

    We appointed ESC to review all historical data related to our site. They demonstrated a very high level of technical expertise and understanding of the JTC EBS Guidelines which proved invaluable in our response to JTC. ESC was extremely responsive and we are very satisfied with the outcome.
