Nebraska Department of Environmental Quality
Air Quality Division
Notice is given to the public, according to Chapter 14 of Title 129 - Nebraska Air Quality Regulations, of the application of S.W. Energy, LLC for permission to modify the existing construction permit for an ethanol production facility, SIC code 2869, located at 71637 Road 380, McCook, Red Willow County, Nebraska, to increase production of denatured ethanol from 27.5 to a maximum of 63 million gallons per year of denatured ethanol, with associated increase in production of dried distillers grain with solubles (DDGS) and wet distillers grain with solubles (WDGS).
The potential and permitted emissions of air contaminants anticipated due to the construction of the modified ethanol plant are estimated in the following table:
Regulated Pollutant | Potential Emissions | Permitted Emissions |
 | (tons/year) | (tons/year) |
| Particulate Matter (PM) | 65.87 | 65.87 |
| Particulate Matter smaller than or equal to 10 microns (PM10) | 47.63 | 47.63 |
| Sulfur Dioxide (SO2) | 32.54 | 32.54 |
| Oxides of Nitrogen (NOx) | 64.80 | 64.80 |
| Carbon Monoxide (CO) | 89.71 | 89.71 |
| Volatile Organic Compounds (VOC) | 67.15 | 67.15 |
| Hazardous Air Pollutants (HAP): | | |
| Acetaldehyde | 7.37 | <10 (any single HAP) |
| Total HAPs | 10.56 | <25 |
Red Willow County is in attainment with the National Ambient Air Quality Standards (NAAQS) for all regulated pollutants and is expected to continue to be in attainment. Red Willow County is in compliance with the state Total Reduced Sulfur (TRS) standards and no TRS emissions are expected from this project. 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 - Nebraska Air Quality Regulations, which:
· limit type of fuel combusted in the boilers, DGS dryer and regenerative thermal oxidizer (RTO);
· require the source to comply with New Source Performance Standards (NSPS) in 40 CFR 60, Subparts Dc, Kb, and VV;
· limit PM, PM10, NOx, CO, VOC, and/or HAP emissions from major emission units;
· require the use of particulate and VOC control devices;
· require the use of Best Available Control Technology (BACT) for HAP control;
· require all truck haul roads to be paved;
· require control of fugitive dust emissions from truck haul roads;
· limit drift loss and total dissolved solids (TDS) content of cooling water;
· specify minimum stack height requirements;
· require public access restriction;
· require the source to conduct performance testing; and
· require the source to keep records documenting compliance with the permit conditions.
The proposed permit and supporting materials are available for inspection at the office of the Nebraska Department of Environmental Quality, Suite 400, 1200 "N" Street, Lincoln, Nebraska 68508. These materials were also forwarded to the McCook Public Library. Telephone inquiries may be made at (402) 471-2189.
