This information should have been made more public to the citizens of Maricopa. This meeting was a PM10 Stakeholders Meeting in regards to: Initial stakeholder discussion of the accompanying draft of a rule establishing PM10-related emission standards for commercial feedlots.

"The number of PM10 exceedances at the Cowtown monitor dwarfs the number at any other monitoring site. While other monitors in Pinal County report as many as 25 or 30 exceedances per year, the Cowtown monitor stands alone in consistently reporting more than 200 exceedances per year."

"At the Cowtown monitor, manure constitutes the dominant fraction of PM10. A 7 chemical speciation study found that at PM10 monitors other than the Cowtown monitor, manure constituted no more than 20% of observed particulate matter. However, at the Cowtown monitor a chemical speciation analysis indicated that more than 60% of observed particulate matter consisted of manure."

"The combination of the number of PM10 exceedances and the very high PM10 concentrations observed at the Cowtown monitor result in the AIRS AQS system reporting that for PM10, Pinal County constitutes the most polluted place in the country."
