32 • March 2016 www.concreteproducts.com Vulcan Materials has published North Ameri- ca's first self-declared Environmental Product Declaration for aggregates. The document pro- vides data for four primarily concrete-grade fine and coarse aggregates, plus eight oth- er grades best suited to base, drainage and asphalt from the producer's Pleasanton, Calif., quarry. The operation serves the San Francisco Bay Area market, where design professionals and facility owners seek supplier or manufactur- er EPDs to satisfy new green building rating requirements or incentives, especially those in the U.S. Green Building Council's LEED v4 and American Institute of Architects' Archi- tecture 2030 Challenge for Products. With heavy certified project and building square footage contributions from the Bay Area, Cal- ifornia ranks among USGBC's Top 10 States for LEED 2015. The Pleasanton EPD provides aggregates' cradle-to-gate impacts using a 1 metric ton declared unit, and reflects a Life Cycle Assess- ment (LCA) per International EPD System: NEWS SCOPE PRODUCERS The EPD is posted at www.vulcanmaterials. com under Construction Materials/Product Declaration. It was prepared California soft- ware specialist Climate Earth, which assist- ed Central Concrete Supply in publishing the frst EPD for concrete in North America. Product Category Rule 2012:01 Construc- tion products and Construction services, Version 2.0. Berkeley, Calif.-based Climate Earth Inc. conducted the LCA and devel- oped the EPD for Vulcan Materials, which joins a client roster that includes two other California operators, Central Concrete Sup- ply, San Jose and Angelus Block Co., Sun Valley. An LCA system boundary for the Pleas- anton operation captures principal cradle- to-gate life cycle product stages shown on the accompanying chart: • A1—Extraction and processing of raw materials as well as the fuels used in the production of aggregate and mainte- nance of plant equipment; • A2—Transportation of all input mate- rials and fuels from the supplier to the gate of the sand & gravel plant; • A3—Manufacturing including mining, transportation, crushing, screening, grading, washing, blending and loading concrete aggregate as well as the trans- port and processing of wastes. The study does not encompass a) pro- duction, manufacture, and construction of manufacturing capital goods and infra- structure; b) production and manufacture of production equipment, delivery vehicles, and laboratory equipment; c) personnel-re- lated activities (travel, furniture, office supplies); d) fuel used to transport per- sonnel around the mine and sand & grav- el facility; and, e) energy and water use related to company management and sales activities.

The EPD presents the Product Stage within a "Sys- tem Boundary," where A1, A2 and A3 represent Raw Material Supply, Transport and Manufac- turing at the Vulcan Pleasanton operation. www.nox-crete.com Same form.
