There's been a lot of attention paid to what is often described as the fast-growing frac sand industry, but MPR reports that a slowdown has changed the appearance of places in southeast Minnesota that were booming a year ago.
The sand is used in hydraulic fracturing, or fracking, the process of extracting oil and natural gas from deep below the earth's surface. But natural gas prices are down and so is demand for the sand, MPR reports. MPR visits a rail terminal in downtown Winona where so much frac sand once filled the terminal that residents dubbed it "Mt. Frac." Now the Modern Rail site sits empty, MPR says.
The pile of sand in Winona's downtown sparked controversy and debate, as it has in other areas of southeast Minnesota. The sag in gas prices and the lull in frac sand industry activity have given local and state leaders an opportunity to reassess rules and regulations.
State lawmakers have been considering several frac sand mining bills, including one that calls for a one-year moratorium.
