Sustainable ‘green’ practices have been a growing focus as individuals, corporations, and governments consider issues such as global warming, highly volatile markets, and urban sprawl. For a Fortune 100 mining company, these concepts have become a key part of managing cleanups and hazardous waste sites to increase the environmental, social, and economic benefits of the cleanups. The company needed to address acid mining drainage from large rock piles as well as the potential for rock slide risks at the site. The cleanup solution originally supported by the Environmental Protection Agency (EPA) and State was complete removal of the rock piles and transport to an offsite disposal location. However, this could take more than 20 years to complete, at a cost of approximately USD $180M. The solution would also increase hazards to the public through exposure to years of heavy truck traffic through small towns, and produce millions of tons of greenhouse gases.
Integral Consulting, Inc., a science and engineering firm that provides multidisciplinary services in the fields of health, environment, technology and sustainability, was hired by the mining company to assist with evaluating remediation (aka cleanup) strategies for a 100-year-old mine. The Integral team used Palisade’s @RISK to evaluate multiple strategies and select a solution that minimized environmental impact and achieved full regulatory approval, while enabling the client to save more than USD $100M. The company’s mission is to help clients across a wide range of public and private enterprises to identify technically sound, cost-effective and environmentally friendly solutions to complex problems.
“@RISK enabled us to do sensitivity analysis on each criteria, which helped us determine how specific uncertainties could drive different decisions,” explained Timothy Havranek, Principal Consultant for Integral Consulting. “It let us easily identify which choice was optimum for our client, for the community and for the environment.”
