requirements for air pollution control devices that reduce particulate matter (e.g., baghouses). This rule applies to operators of air pollution control devices venting processes that have direct particulate matter emissions, such as concrete batch plants, asphalt batch plants, and rock and aggregate plants.
pozzolan, can readily be substituted for 15% to 35% of the cement in concrete mixes, according to the U.S. EPA. For some applications fly ash content can be up to 70%. Of the 51 million tons of fly ash produced in 1991, 7.7 million tons were used in cement and concrete products, according to figures from the American Coal Ash …

West Dallas is also a community that knows how to fight: It was only due to decades of their activism that the smelter was shut down, and the federal government established a Superfund site in the 1990s to clean up the contamination. They recently pushed to get two concrete batch plants that were violating their permits shut down, …
Gunter, located about 50 miles north of Dallas, already has 11 permitted concrete batch plants, according to Texans for Responsible Aggregate Mining, and now another one is on the way, worrying residents who say the dust and particulate matter plants release is polluting the air they breathe.
At concrete batch plants, workers combine materials like sand, water, cement and other raw materials to create concrete for construction sites. In Texas, concrete, cement and other aggregate industries (such as gravel and sand quarries) generate more than $10 billion in revenues each year, according to the Texas Aggregates & Concrete …

The ISC3-ST model was applied to estimate air dispersion of the contaminants emitted by the cement plant. Air concentrations of NO(2), SO(2), PM(10), metals, and polychlorinated dibenzo-p-dioxins and dibenzofurans (PCDD/Fs), as well as the potential exposure in the vicinity of the facility, were assessed via models based on US EPA guidance ...
Concrete batch plants are popping up throughout Texas to meet demand spurred by development in the nation's fastest-growing state. The number of applications for air quality permits for batch...
Adverse health effects of cement plant exposure have been found in occupational contexts but are less defined for the general population living near plants. We aimed to summarize the evidence on the health effects of people exposed to ambient air pollution by cement plants. A systematic review using Embase, PubMed and Web of Science was performed.

concrete batch plant a ma-jor source of air pollution. And, compared with other industries, it isn't. However, most states re-quire air permits for the equipment and ac-tivities typically found at concrete plants. Although most concrete plant operators don't obtain air permits on their own, with a little guidance they can submit an appli-
Nov. 11, 2022 Updated: Nov. 11, 2022 6:43 p.m. 3. SAN ANTONIO — For the first time in a decade, air quality standards for concrete batch plants are up for revisions in Texas, and critics who ...

It is highly unlikely that most concrete plants could have potential to emit greater than 100 tons per year of either of these pollutants, or of the others. One exception to this may be a site containing one or more plants, or a site with other air emission sources present (such as crushed stone, ce- ment, asphalt, etc.).
