WDIO reported that Minnesota state says US Steel had multiple air quality violations at Keewatin Taconite. The Minnesota Pollution Control Agency says the company has agreed to pay a nearly $50,000 civil penalty for nine state air quality violations.
The company is also required to submit an enhanced dust control, mitigation and response plan to the MPCA within 90 days.
The agency determined the Keetac taconite facility began to periodically violate Minnesota''s fugitive, or airborne, dust rule in early December 2012. Nine events occurred between that date and Feb. 4, 2015. The rule requires that facilities take steps to control avoidable amounts of particulate matter (dust emissions) from sources such as mining, roads, ore handling and stockpiles from becoming airborne.
Keetac''s taconite production facility includes a basin where the company deposits tailings from taconite pellet production. During periods of high winds, drought or sometimes freeze/thaw conditions, tailings dust can become airborne and deposited beyond the facility''s property.
Keetac has been idle since May of 2015, because of the domestic steel industry crisis.
