PUBLIC COMMENT PERIOD

Draft Product Category Rules (PCR) for Asphalt Mixtures


Public comment period closed on September 9, 2021. Responses to the comments will be included in the final PCR. Thank you to all who submitted comments. If you have any questions please contact us.

NAPA’s Emerald Eco-Label environmental product declaration (EPD) software will be updated when the revised PCR takes effect in February 2022. More information regarding updates to the Emerald Eco-Label software will be announced this fall.

Updates to the LCA of Asphalt Mixtures in Support of an Environmental Product Declaration, July 2021

Summary of Proposed Changes to the PCR

Version 2 of the PCR has been updated in accordance with the newly revised underlying LCA and also to reflect changing conditions within the general area of LCA and EPDs for construction materials. Key changes to the PCR include the following:

  • Changed the core PCR from EN 15804 to ISO 21930 to be more consistent with other EPD programs in North America. This change required substantial reorganization of the PCR.
  • Expanded the geographic applicability of the PCR to include Canada as well as the United States.
  • Revised Annex I to utilize the latest available upstream (secondary) datasets for energy and materials.
  • Clarified guidance regarding comparability of EPDs for asphalt mixtures.
  • Added new requirements to enable development of EPDs for portable asphalt plants.
  • Clarified system boundaries for secondary (recycled) materials and added a requirement to use foreground (plant-specific) data for transportation of reclaimed asphalt pavement (RAP) and recycled asphalt shingles (RAS) instead of using a generic pre-determined parameter.
  • Added new requirements to enable development of EPDs for asphalt mixtures produced using cold central plant recycling (CCPR) technology.
  • Added new requirements to account for disposal of waste materials and by-products produced during asphalt mixture production (e.g., baghouse fines).
  • Improved transparency regarding asphalt mixture materials and content of regulated hazardous substances.
  • Enhanced the additional environmental information provided in EPDs, including:
    • Indicating potential GHG emission reductions from the procurement of clean energy through market-based instruments such as on-site renewables and renewable energy certificates (RECs),
    • Indicating a company’s participation in ENERGY STAR programs,
    • Indicating a company’s implementation of an environmental management system (EMS), and
    • Providing a recommended default transportation distance at end-of-life (C2) for RAP when asphalt mixture EPDs are used as a data source for pavement LCA studies.
    • Providing information related to release of dangerous substances from construction products.
  • Clarified requirements for verification of software based EPD development tools.
