General Information
Event Name: Monthly Engineering Forum Virtual Training
Topic: Mississippi Phosphates Corporation Superfund Site
Hosted By: U.S. EPA
Office of Superfund Remediation and Technology Innovation
Event Description:

The Engineering Forum (EF), established in the late 1980s, is a group of engineers and scientists that supports the Superfund and RCRA programs in each of the ten EPA Regional Offices. As one of the EPA Technical Support Project’s (TSP) three technical forums, the EF is a medium for exchanging technical information regarding innovative site cleanup and characterization technologies. Monthly technical talks focus on site-specific engineering problems encountered, alternatives and solutions, and lessons learned. After each presentation, information regarding upcoming events and training are discussed and time for an Open Mic discussion is provided. If you are a Superfund, Resource Conservation and Recovery Act (RCRA), Brownfields, state or federal environmental professional who is interested in solving technical issues, register for any technical talks listed below that interest you and join the discussion!

Presentations are specifically designed for EPA staff including RPMs, OSCs, Corrective Action Managers, Superfund and Technology Liaisons, Chemists, Biologists, Physical Scientists, and Engineers from within EPA regions, program offices, laboratory system, and headquarters personnel as well as environmental professionals from state agencies, tribes, the U.S. Army Corps of Engineers, U.S. Dept. of Energy, and other federal agencies of all experience levels. THIS TRAINING IS NOT OPEN TO ACADEMIA, CONTRACTORS, CONSULTANTS OR OTHER PRIVATE ENTITIES.

We will try to meet any special accommodations necessary for our participants as possible if given a minimum of two weeks notice. You will be prompted to indicate if you need any special accommodations upon registering for these events.

*This training is offered free of charge to all registrants who are confirmed to attend. One CLP will be issued for each session attended when you register and log on with the registration link provided to enable your attendance to be confirmed.*

Additional Information:

Activities at the former Phosphates Corporation Site produced a gypsum waste product that was stored in two stacks onsite. The 300-acre east gypsum stack holds 15 million yd3 of exposed material leaches acidic wastewater during rainfall. A water treatment plant was installed to treat the wastewater. It has cost EPA ~$48 million to date to operate and maintain. To cut cost, a value engineering study for the east gypsum stack was conducted in June 2018 to weigh capping options. EPA found the ClosureTurf® Cover System engineered turf could properly cap the exposed material and save about $6 million in 30-year life cycle costs, when compared to traditional soil cover systems. The system is easy to install and repair, has a lower operation and maintenance cost, and is more resilient to extreme weather conditions. Installation will begin in April 2020 with a completion date in 2021-2022.
