Colorado Public Works Journal, Summer 2022

10| ColoradoPublic Works Journal UPDATES Works News APWA Colorado Celebrates 60 Years! The Colorado Chapter of the American Public Works Association is celebrating its 60th anniversary this year and to mark the milestone, the Chapter hosted a celebration on June 30 at John Meade Park in Cherry Hills Village. This was the perfect place to host the event as the redevelopment of this park was the 2021 APWA Colorado Project of the Year! Public works professionals from around the state gathered and enjoyed networking and catching up with each other as well as some great BBQ! Several of the Chapter’s past presidents attended including one of the charter members from 1962, Jerry Weiss. Mr. Weiss (see right) was also president of the Chapter in 1969 and is the first father-son occurrence in Chapter history, his son, Chuck Weiss is now a Director on the Colorado Chapter board! John Burke, Chapter Director, did a brief recognition of past presidents, board members and Korbitz winners and took a nostalgic trip down memory lane of music, events, and prices in 1962 – how things change and yet some are still relevant! It was great to see so many old friends and new faces at the celebration and APWA hope you will join them at events throughout the year to continue to celebrate! According to a new report from the National Asphalt Pavement Association (NAPA), cradle-to-gate emissions associated with U.S. asphalt mix production represented approximately 0.3% of total U.S. greenhouse gas (GHG) emissions in 2019. By comparison, U.S. EPA data indicate that transportation emissions from fossil fuel combustion represented 27.8% of total emissions in 2019, while industrial emissions represented 25.3%. The report, GHG Emissions Inventory for Asphalt Mix Production in the United States (SIP 106), is the first national cradle-to-gate assessment of GHG emissions associated with the production of asphalt pavement mixtures that uses a life cycle assessmentbased methodology. “Publishing this report puts NAPA and the asphalt pavement industry at the forefront of transparency among carbon emitters,” said NAPA President & CEO Audrey Copeland, Ph.D., P.E. “We’re demonstrating our commitment to doing better by taking stock of where we are and identifying proven as well as innovative strategies to reduce carbon emissions.” NAPA Releases First-of-its-Kind Emissions Inventory for Asphalt Pavement Mixtures Jim Mertes, Director of Environmental Affairs at Construction Resources Management, Inc., A Walbec Group Company, and Chair of NAPA’s Sustainability Committee, described the report as “a comprehensive industry benchmark, which can be used to measure future industry improvements in carbon reduction.” Additionally, “it identifies what we can achieve using existing strategies and technologies and demonstrates the unprecedented technological challenge ahead to get to net zero.” By identifying ‘avoided emissions,’ the report demonstrates how existing environmentally preferable technologies like RAP, WMA, and switching to alternative fuels for plant operations have already had an industry-wide impact on limiting emissions. In 2019 alone, the industry avoided 2.9 million metric tons (MMT) CO2e emissions – equivalent to the annual emissions from approximately 630,000 passenger vehicles. “New technologies and additional innovative practices will need to be developed and implemented to achieve more significant GHG emission reductions,” the report states
