The Construction Material Processors Association (CMPA) is dedicated to the representation and service of its Members in the Victorian Earth Resources Industry.The CMPA was formed to represent a broad spectrum of those involved in construction material processing businesses.Evolving from industry pressure for a peer network of independent quarrying companies, the CMPA now has an established membership base representing businesses involved in the extraction, processing or otherwise working in hard rock, gravel, sand, masonry, clay, lime, soil, gypsum or recycling; industry consultants, industry suppliers and any industry worker.Since inception the CMPA has been successful in representing Members' interests to government on issues including rehabilitation bonds, the development of a Work Safely Reference Manual, a Preferred Suppliers & General Information Reference Manual and administration documents – including plant safety checklists and employee wage books. Training courses for industry employees have also been instituted.
