A linchpin of forthcoming block and hardscape Environmental Product Declarations (EPD), the draft Product Category Rule (PCR) for “Manufactured Concrete and Concrete Masonry Products” is available here for review and comment through May 16.
The PCR provides EPD preparation requirements for a variety of products, including concrete masonry and segmental retaining wall units, plus manufactured stone veneer. In turn, EPD requirements or incentives are emerging in project specifications or contracts as green building rating systems drive such documentation. NCMA has engaged ASTM International for the PCR and prospective EPD development and certification. Additional information on the PCR can be obtained from NCMA Research and Development Manager Nick Lang, 571/224-0935; firstname.lastname@example.org
