Fall 2022 9 WWW.CO-ASPHALT.COM ASPHALT & THE ENVIRONMENT Environmental Product Declarations (EPDs) What are Environmental Product Declarations? An Environmental Product Declaration (EPD) is a Type III Environmental Label as defined in ISO Standard 14025:2006, Environmental Labels and Declarations. EPDs communicate the environmental impacts of a product or service using Life Cycle Assessment (LCA). The process used to develop an EPD ensures consistent data collection, analysis and reporting requirements, supported by third party verification. This ensures the reliability of the information communicated through an EPD. EPDs report the CO2 Equivalent (kg) generated by producing 1 ton of asphalt impacting Global Warming Potential (GWP). Environmental Product Declarations in Colorado? Colorado passed House Bill 21-1303 Global Warming Potential for Public Project Materials and the Governor signed it into law earlier this year. CDOT (for transportation projects) and the Office of the State Architect (for building projects) will be establishing policy to develop Environmental Product Declarations for a number of construction products including asphalt and asphalt mixtures for. They will have a 2-3 year study and developmental period and then required starting in January, 2024 (OSA) and January 2025 (CDOT). CDOT categories include Bid Items 403 (Hot Mix Asphalt / Stone Matrix Asphalt) and Item 411 (paid separately, it shall be in the 403 EPD submittal). EPD submittal requirements shall be required for those projects that include the Standard Special Provision – Revision of Sections 101 and 106 – Materials Environmental Product Declarations. A project cost limit threshold of $3 Million, based on the Engineer's Estimate of bid items/quantities for which the Contractor submits a bid. The $3 Million threshold limit is not to include Construction Engineering (CE) and Indirect Costs, nor is it to include Force Account (FA) items. The $3 Million project threshold will be used for the initial EPD collection effort and may be revised in the future to include projects with a smaller engineer estimate bid item total. How do I create an Environmental Product Declaration? The National Asphalt Pavement Association has created the Emerald Eco-Label Tool (web-based software) to provide comprehensive, credible, and comparable environmental data to end users (engineers, specifiers, users, and producers) that can be used in future pavement EPDs. Emerald Eco-label program standardizes industry specific LCA assumptions, allowing for credible and transparent reporting. The Colorado Asphalt Pavement Association has also created an EPD workgroup to provide support and resources to the Industry.
