Air quality

Iowa’s Department of Natural Resources is giving University of Iowa a unique air quality permit that will provide the UI flexibility in using renewable fuels as an alternative to coal.

The ‘Plant-wide Applicability Permit’ enables the UI to average air quality across the 437 emission sources on the campus, instead of reporting individually.

DNR Director Charles Gipp says the permit -- one-of-a-kind in Iowa -- allows the UI to try new, renewable energy sources without violating air quality standards.

A state lawmaker from Cedar Rapids today grilled the director of the Iowa Racing and Gaming Commission over a proposed license for a smoke-free casino in their city.  

The commission denied Cedar Rapids a gaming license in 2014, citing a saturated market for casinos.  

The city is arguing that a smoke-free casino would fill an unmet need, since smoking is allowed in other gambling houses, an exemption to Iowa’s law banning smoking in public places.

Controversy over so-called “frack” sand mining is heating up in northeast Iowa. A community meeting Wednesday evening in Decorah will focus on concerns about the possibility of mining development in Winneshiek County.

Fine sand can be used in the hydraulic fracturing process known as “fracking.” The technique is used to remove natural gas and oil from deep underground. There’s not any oil or gas fracking in Iowa right now – but there is a sand mine in northeast Iowa’s Clayton County, which is shipping frack sand out of state.
