The National Slag Association (NSA) celebrated their 100th anniversary during the Annual Meeting held in Washington DC, USA in September 2018. 

“I would describe the National Slag Association as our big brother, it’s been around many more years than us and, in many regards, when we formed our association in 1990, we fundamentally framed it on the way that the NSA operate, and it served us very well in terms of the structure.”

- Craig Heidrich, ASA Executive Director
