Overview

With the impact and enforcement of the Federal Coal Combustion Residuals (CCR) Rule, owners and operators of coal ash impoundments have been engaged in and are facing the closure of their impoundments. This course shares the expertise of industry leaders from multiple closure service providers. The purpose of the course is to give individuals involved with closure projects either directly or indirectly, a more comprehensive understanding of the process and steps involved in closure of these impoundments. The program will dive into detail on a variety of those steps such as: geotechnical work, dewatering, stability issues, civil design, cover design, groundwater monitoring and corrective action, project scheduling, construction approaches and contractor selection, and finally post closure land use.

Learning Outcomes

Review the information to look for in geotechnical investigations and receive recommendations

  • Engage in a discussion on dewatering selection and management and the steps needed and taken during the process
  • Listen to experts discuss structural stability issues and their solutions for closure
  • Discuss the civil design of a closure and its steps and process
  • Review the requirements and types of final cover design
  • Engage in a review of the groundwater requirements, detection systems and best practices
  • Discuss the final site closure and methods and best practices
  • Review lessons learned and methods for project scheduling of these projects
  • Listen to various construction approaches and methodologies from a contractor’s perspective
  • Engage in an overview of the contractor evaluation process for closure projects
  • Review post closure land use opportunities and planning for future use
