RMC Research Foundation 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.
