As more utilities adopt the use of sustainability metrics and reporting as a standard way of communicating their concern and responsiveness to the public, the issue of green and sustainable remediation gains prominence. Ameren has made sustainability reporting one of their major management initiatives. This presentation discusses the steps involved in evaluating sustainability metrics for remedial alternatives at typical MGP sites. The evaluation compares remedies incorporating: excavation, in situ solidification, in situ thermal treatment and in situ chemical oxidation. GEI Consultants, Inc., Ameren’s MGP Program Management Consultant has worked to develop a pilot program to integrate Green and Sustainable Remediation (GSR) practices into the remedy selection process for their portfolio of sites. The framework is based on Ameren Sustainability metrics and the requirements of the Illinois Environmental Protection Agency (IEPA), and follows the ASTM Standard guide for integrating sustainable objectives into cleanup. The evaluation process uses tools developed by the United States Environmental Protection Agency (USEPA) under their initiative for Greener Cleanups.
