44 • November 2017 www.concreteproducts.com FEATURE ENVIRONMENTAL AWARDS CENTRAL REGION SECOND PLACE DICKINSON READY MIX CO. WESTGATE AVENUE PLANT • DICKINSON, NORTH DAKOTA Regular inspections ensure the DRM flagship facility can consistently exceed federal government, state of North Dakota, and city of Dickinson environmental requirements. An Environmental and Safety Director is tasked with stay- ing current on compliance measures, and ensuring staff are informed of new requirements affecting daily plant and site routines. Management and staff maintain good rapport with environmental officials through sit down discussions and facility tours. DRM also hosts tours for elementary to high school student groups, and is assisting in concrete curric- ulum development as part of its Dickinson Middle School STEM (Science, Technology, Engineering and Mathematics) Program sponsorship. The producer has occupied the Westgate site for 40 years. Following construction of a new batch plant, office and truck shop in 2010, it completed an enclosed truck washout facility last year. Drivers acidize and clean their trucks in the sheltered setting, which DRM presents as a "a giant step forward from washout pits. It is used under all weather conditions and recycles all washout and wash down water." Aggregates and cementitious materials from the primary wash out cell are transferred to a drying room and used as fill material. Water is continually reused for truck washouts, negating fresh-water use. DRM trucks carry Enviro-Bags for jobsites where contractors fail to provide adequate wash out areas. Drivers wash only mixer chutes in the field; excess concrete is returned to the plant for recycling. The first priority for returned concrete is casting of EcoBlocks. Consistent with the Westgate batch plant enclosure, the new washout facility is of cast-in-place, post-tensioned concrete construction. It brings critical driver functions under roof and eases process water, aggregate and cement fine recy- cling. Outside, DRM continues to create more dust-curtailing hard surface area, while adding tree plantings and taking other good-neighbor measures.
