The National Stone, Sand and Gravel Association (NSSGA) announced the Gold, Silver and Bronze winners of NSSGA's Safety, Environmental and Community Relations Excellence Awards. The program recognizes aggregates operations throughout the United States and Canada for their extraordinary commitment to safety for their superior performance as environmental stewards and for their community involvement and support activities that have enhanced the image of the aggregates industry during 2009-2010. All Gold Awards in each category were presented at NSSGA's 2011 Annual Convention in Las Vegas on March 23. Operations that accumulated Gold Awards in Safety, Environmental or Community Relations over a five-year period also received a Stars of Excellence Award at the Annual Convention.
