In association with the ongoing Energy Transition, the Power Industry has undertaken hundreds of CCR Unit closures. By some accounts, the total closure compliance cost to date is over $15B USD . Closure engineering and construction process state of practice has evolved significantly through execution of these major projects. Closure can be viewed through the following progressive processes:•Ash Characterization•Dewatering•Excavation•Moisture Conditioning•Transport•End PlacementThis presentation takes a deep dive into the collective wealth of experience in CCR engineering and construction management afforded by the authors. Each closure process is tabled thru the criteria of:•Objectives•Proven Solutions•Lessons LearnedThrough this distilled down “straight talk”, both novice CCR and industry experts will find clarity on how we have advanced the practice and where there are opportunities for continued innovation. The discussion concludes with a holistic evaluation of realized ash handling production rates associated with several major closure projects under a wide array of site conditions. Ultimately, realized production rates are directly impacted by one or more of the closure processes identified above. The impacts typically come in the form of site or construction process “constraints”. Production rates from the case histories are linked to the site-specific constraint logic outlined to provide the audience with this valuable insight on CCR mass material handling realities.
