Approved Steingline stated that proposed paved haul road and the current irrigation system to water down the areas that are not paved will help to mitigate the dust problem. If the proposal is not approved the site it will remain as it is and since the area is made up mainly of clay, which turns to powder, it is difficult to control the dust. The asphalt plant will help control the dust problem,by paving a road. Zisla stated that if there is a current dust problem that they need to address it now to be considerate to their neighbors, and not use the approval of the application as the only way to fix this issue. He then inquired what is on the other sixty to seventy percent of the site. Steingline stated that there is nothing on the remaining part of the site, except for some bins with rocks in them, it is mainly a field. Zisla asked how much of the site would they be using if the application is approved. Steingline replied that they would use at least another forty percent of the site. Steingline added that he did not mean to suggest that the only way to control the dust is by approving the application. If the application is approved it will allow Belair to have a way to pave a large portion of the site to help control the dust. Libby Henderson, Wank and Associates, stated that the steam plume is generated as the aggregate is dried. The plume is made up mainly of water, a little bit of dust in it and some particles off of the asphalt. The asphalt particles are regulated by the federal and state rules. A bag house is added to remove most of the pollutants from the drum operation. This tends not to be an odor issue. However, filling and empting of the silos tend to be an odor source. The odor particles tend to be a small, however they don't have much velocity behind them, and they tend to loft slowly out of the area and because they are so small there are not regulated. The new technology allows the operator to design the layout of a new system that pulls an air stream off of the silos. The displaced air then gets routed to the drum,which is used as combustion air and the vapors are burned off. She has talked to Midwest and they are willing to set up the silos in this manner. She stated that Belair was not aware that there were continuing dust problems since they put in the irrigation system. Improved communication with their neighbors would solve this problem. The irrigation system is state of the art technology that rings the site and can water the piles if necessary. O'Brien asked if the odor used as combustible air will it eliminate the odor completely or just a percentage of the odor. Henderson replied that it should burn off the biggest odor source. O'Brien inquired if the silos are completely enclosed. She stated that they are open when they are being filled and there is a small vent on the top, they can't be tight because they are so hot. Dave Fox, Fed-Tec at 4760 Mustang Circle, stated that in 2002 and 2003 he sent a letter to New Brighton in regards to the dust problem. The City brought it to Belair's attention. Mike Murlowski asked him not to send another letter to the City, but to please deal with him directly regarding the dust matter. So, every time there is a dust problem he has to call Murlowski and ask him to deal with the dust problem. The dust from the site gets into his company's air conditioner and heater that are located on top of the building and they maintain the mechanical units three times as often because of it. There are a lot of maintenance issues outside and inside the building because of the dust. He added that while Belair has a state of the art sprinkler system it is not being used. He also believes an asphalt plant next to their property will bring the property value down. C:\Documents and Settings\jgoepe\Local Settings\Temporary Internet Files\OLK28\10-17-2006.doe Page 6 of 9
