New emissions standards for concrete batching
The United States Environmental Protection Agency (EPA) adopted new Emissions Factor, AP-42, data for "concrete batching," located in Chapter 11.12. The changes are a direct result of new data gathered through an RMC Research Foundation study that demonstrated that air emissions from ready mixed concrete manufacturing were significantly lower than the data previously used by the EPA.

Professional staff at the National Ready Mixed Concrete Association (NRMCA) used this new data to successfully advocate for these changes; the EPA's data had not been updated since 1995.

The mission of the RMC Research Foundation is to support research and educational programs that will advance and improve the concrete industry. The revised standard for "concrete batching," as well as other information about the AP-42 study, is available for download from the RMC Research Foundation's Web site.
