The rule seeks to close a loophole created when the Environmental Protection Agency issued a coal ash cleanup rule in 2015. That rule set criteria for existing and new coal ash landfills, but didn't address inactive facilities. Coal ash is the residue from coal burnt to generate power. The ash is typically stored in specially-built landfills.

About 8,500,000 metric tons of coal ash are produced in Malaysia each year, and by 2024, it is expected that 58% of power in Peninsular Malaysia will be generated by coal (Rafieizonooz et al. 2016 ...
