The Winona Planning Commission voted unanimously Monday to table further discussions about air quality and how it relates to the silica sand industry in the city of Winona.
Staff recommended putting off discussion until a representative of the Minnesota Pollution Control Agency can come to Winona and give an update on state efforts and answer questions.
Board member Luverne Olson said he did not think it was fair to put the financial burden of air quality testing on the sand industry or the city. He says until the state can come up with their own air standards it may not pay to start testing.
Board Chair Craig Porter says he doubts the level of sand activity projected in the city will have too many adverse effects on the city's air quality but he wants to hear from the MPCA as well.
The Citizens Environmental Quality Environmental Committee has been meeting to discuss air quality monitoring of frac sand operations.
They have suggested that the decision on air monitoring at the facilities be deferred to the MPCA and the City should consider interim monitoring for crystalline silica if an answer is not immediately available from the MPCA.
