AUGUSTA, Wis - The public has an opportunity to comment on an application to the Department of Natural Resources' Green Tier program from Hi-Crush Proppants for its facilities in Monroe, Trempealeau, Jackson and Eau Claire counties.

Applicants with good environmental records are required to develop and implement an Environmental Management System (EMS), which will be used to set goals, assess progress and identify potential improvements.

Hi-Crush was founded in October 2010 to mine and process premium monocrystalline sand, a specialized mineral that is used as a proppant to enhance the recovery rates of hydrocarbons from oil and natural gas wells.

Hi-Crush currently operates four industrial sand mines with processing and rail loading facilities in Wisconsin, including: Augusta, Blair, Whitehall and Wyeville. Hi-Crush's mineral reserves consist of Northern White sand, predominately found in Wisconsin and limited portions of the upper Midwest region of the United States.

Hi-Crush's business operations have been designed to minimize environmental impacts. The company's processing and rail loading facilities are located on-site, reducing costs and impacts of trucking sand between wet and dry plants. Hi-Crush operations also help lessen air quality impacts by utilizing overland conveying systems to transport mined materials, eliminating the need for trucking or hauling the material with heavy equipment or via diesel burning trucks over local roadways. Hi-Crush's EMS, which went into effect earlier this year, is expected to optimize operations over time and improve environmental performance.

Future environmental performance goals include, but are not limited to:
