PUBLIC NOTICE


Nebraska Department of Environmental Quality
Air Quality Division

Notice is given to the public, according to Chapter 14 of Nebraska Administrative Code Title 129 - Nebraska Air Quality Regulations, that the Department is proposing to issue a construction permit to Green Star Gasifiers, LLC (FID 110490), an 8 megawatt biomass power plant and torrefied wood pelleting facility (Standard Industrial Classification code 4911- Electric Services) located at 1600 Green Star Avenue, South Sioux City, Dakota County, Nebraska. The anticipated change in emissions of regulated air contaminants in tons per year (tpy) due to the proposed construction of this facility will be: 26.43 tpy of Particulate Matter (PM); 6.92 tpy of PM ≤ 10 microns (PM10); 2.56 tpy PM ≤ 2.5 microns (PM2.5); 20.76 tpy Sulfur Dioxide; 39.99 tpy Oxides of Nitrogen; 59.52 tpy Carbon Monoxide; 54.34 tpy Volatile Organic Compounds; 2.14 tpy of Hydrochloric Acid; and 4.35 tpy total HAPs.

Dakota County meets the National Ambient Air Quality Standards (NAAQS) for those pollutants subject to a NAAQS and is expected to continue in that status. No impact is anticipated on habitat for any rare or threatened species.

The Department proposes to issue a construction permit with specific conditions, based on Title 129, which approves the construction of the co-product biomass power plant and torrefied wood pelleting facility. Initial testing is being required by the department to ensure compliance with all pollutant limits established in this permitting action. Additionally, a tiered testing approach for hydrochloric acid emissions is being utilized once the facility reaches full capacity. Under the tiered approach, testing frequency will be determined based up the tested percentage of the permitted limit. The permit also requires the use of control devices and specifies reporting and recordkeeping requirements.

The proposed permit and supporting materials are available Thursday, May 10, 2018 through Monday, June 11, 2018 at the NDEQ, Suite 400, 1200 "N" Street, Lincoln, Nebraska, and electronically at http://deq.ne.gov. Comments received by the Department during this period will be considered prior to the final decision. During this period the applicant, or any interested person or group of persons, may request or petition the Director for a public hearing. The request must be in writing and state the nature of the issues to be raised and all arguments and factual grounds supporting their position. If a public hearing is granted by the Director, the hearing will be advertised by public notice at least 30 days prior to the hearing.
