On Oct. 17, 2023, Massachusetts passed a law that requires all concrete products sold for use within the state to be produced only from aggregate sources that have obtained a license from the Highway Division of Transportation (MassDOT).
The new law not only applies to state-owned, MassDOT projects but to all concrete “structural elements or infrastructure” in the state, including residential projects and private entities.
To obtain a license, aggregate producers must submit test reports to MassDOT to confirm that the aggregate contains a minimal amount of sulfur and pyrite and absolutely no presence of pyrrhotite.
All concrete production facilities, including precast manufacturing facilities that sell products within Massachusetts, must use aggregates only from MassDOT approved sources and must keep a record of those sources on file for at least 30 years.
The new law goes into effect on July 1, 2024, and has sweeping consequences for anyone who provides precast concrete products for any project in Massachusetts.
