Dr. Feyereisn discusses the health risks sand mining brings to a community caused by silica mining and transportation, diesel particulates, acrylamides, and increased truck traffic. He also makes recommendations, including a Minnesota silica particulate air standard; placing facilities in the least populated areas; monitors every 1000'surrounding mining and transportation facilities; acrylamide monitoring of holding pond water, drying facilities and sand waste; and no road transportation of sand (rail car only).

Silica sand is used as a proppent in the hydraulic fracturing process in the gasfields of PA. It causes silicosis, a fatal disease. The Wyalusing Silica Sand Transfer Station is located within a mile of 3 public schools and right next to a large daycare center. Watch this video to see how silica dust is spread across the nation.
Environmental scientist Dr. Yuri Gorby and retired UAW Health and Safety Officer Joe Shervinski are featured in the video.
As Mine Protections Fail, Black Lung Cases Surge View
A joint investigation by NPR and the Center for Public Integrity (CPI) has found that McCowan is not alone. Incidence of the disease that steals the breath of coal miners doubled in the last decade, according to data analyzed by epidemiologist Scott Laney at the National Institute for Occupational Safety and Health (NIOSH). "These people are being exposed [to] three to four times the silica exposures for periods over 20 years. [They have] a chest full of silica and nothing's been done about it," says Bob Glenn, a black lung consultant for NMA. Excess silica forces mining companies to meet a lower standard for coal dust. The idea is that less exposure to coal dust means less exposure to silica.

Lang (Nov 2013). Excavation of the Hawk’s Nest Tunnel...Acute Silicosis. View
764 workers died of silicosis because they mined this cite. 60% of men worked less than 2 months, 80% less than six months, 90% less than a year. Workers acquired acute silicosis, which is caused by massive overexposure to freshly fractured, high-silica dust. It kills within a few years after as little as 2 months exposure.
Rook Station in Greentree Boro near Pittsburgh has a new neighbor in the railyard, a major FracTech frac sand operation. Frac sand comes in on trains and is loaded onto tractor trailers. Residents are being subjected to sand dust which can cause silicosis. The large trucking operations of FracTech and Modern Transportation are violating ACT 124 by allowing diesel engines to idle longer than 5 minutes.
Pierce-2013-Particulate and Silica Health Risk Research. View
(1-20-13) Particulates in the air around sand mines and processing plants have been measured on six occasions.1- to 5-minute multiple "snapshot" samples found that the measured levels of PM2.5/4 increased starting from the Chippewa Falls EOG plant construction through full operation;PM10 levels during operation were higher than the DNR model-predicted maximum concentration and the EOG 24-hour measured levels;Measured levels of PM2.5 at EOG, Superior Silica Sands (Auburn), and Fairmount mine (Menomonie) were 1.7-22 micrograms/m3 higher than concurrent DNR regional levels;
Sand From Fracking Could Pose Lung Disease Risk To Workers View
Esswein (from NIOSH) and his colleagues visited 11 fracking sites in five states: Arkansas, Colorado, North Dakota, Pennsylvania and Texas. At every site, the researchers found high levels of silica in the air. It turned out that 79 percent of the collected samples exceeded the recommended exposure limit set by Esswein's agency.
There were some controls in place, says Esswein, who notes that "at every site that we went to, workers wore respirators."
But about one-third of the air samples they collected had such high levels of silica, the type of respirators typically worn wouldn't offer enough protection.
This March 2013 report was prepared at the request of the Environmental Quality Board to look at issues related to the silica sand mining industry and prepare information on what is known and what is not known. This report has been chosen to receive a 2013 Notable Documents award from the Legislative Research Librarians section of the National Conference of State Legislatures.
