California EPA Determines Asphalt Paving fumes as low priority

posted in: CURRENT EVENTS | 0

CalEPA began an investigation based on the State proposition 65 program in 2016. After testimony by many different entities it was determined the fumes emitted during the production and placement of Asphalt Paving Materials (APM) were to be considered a “Low” priority. This decision is a precedent leaning decision for other states to use when challenges are made about the fumes from the production and placement of APM. The Asphalt paving industry has worked tirelessly over the past 10 years to reduce fumes by the development of new paving and production equipment as well as new processes for producing APM. The fast tracking of Warm Mix Asphalt has been a positive step in the reduction of Fumes as well.
In Colorado we are encouraging local agencies, private developers and the state DOT to recommend or require the use of WMA when ever possible as a fume reduction process but also as a Workability Mixture Additive
