World of Coal Ash, the coal combustion product industry's longest-running international event, drew a record turnout this year with more than 800 attendees participating in short-courses, presentations and the largest ever exhibition held at the Nashville Convention Center in Nashville, Tennessee. The Asian Coal Ash Association participated as an exhibitor at WOCA, promoting the upcoming Coal Ash Asia 2015 event. AsianCAA also assisted in the organisation of a delegation of industry leaders from China, in collaboration with ITIBMI and Coal Ash Solutions Ltd. AsianCAA chairman David Harris also participated as a keynote speaker and panelist in the plenary session.
The record turnout at WOCA 2015 was accompanied by renewed optimism amongst WOCA participants, widely attributed to the US Environmental Protection Agency's December 2014 signing of the final ruling on "Disposal of Coal Combustion Residuals". This final rule supports the responsible recycling of CCRs by distinguishing safe, beneficial use from disposal. Following 6 years of extensive study on the effects of coal ash on the environment and public health, the final ruling delivers a degree of regulatory certainty around disposal, transportation and utilisation of coal combustion products. This regulatory clarity provides guidance and mitigates regulatory risk for industry stakeholders looking to make responsible investments in ash management and utilisation.
