Regular City Council Meeting Monday, May 18, 2009 Page 20 Mr. Peterson addressed improved industry technologies proposed for this plant, including a "knock-out system" and a "bag house;" allowing for larger particles to be removed from the system and filtered through various filter bags and recycled through the plant, allowing for minimal particulates leaving the stacks. Ms. Henderson advised that people would observe steam from the stacks as the drum dried water off the rocks; and that typically odor would emanate from the raw asphalt or product prior to its shipping, rather than from the stack itself. Ms. Henderson opined that typically, those odors would be short-term, and would shift with prevailing winds, making them difficult to identify. Mr. Peterson noted that their Minneapolis plant operated on two acres of land, north of Lake Street off Cedar Avenue, with an apartment building immediately adjacent to the property; and that they had never received any complaints of smoke or odor. Mr. Kittleson noted that the Minneapolis plant operated on a "wet-wash system," and was not nearly as efficient as the proposed system in Roseville; with this plant proposed as warm rather than hot mix, providing for cleaner operations. Ms. Henderson advised that data predicting a scope for emissions traveling from a stationary site were not a typical request or requirement of the regulatory body in the permitting process. Further discussion included the height of the stacks, estimated to be 70' or below; explanation by the applicant of the process for collection of materials from old roads and how it was crushed and .recycled into a usable size and elements blended at the plant with virgin aggregate from quarries in the metropolitan area; transfer of gravel from a pit in Inver Grove Heights and aggregates from suppliers (limestone) from Burnsville and other sources by truck, and hopefully by a rail spur on site. Councilmember Pust sought clarification for the company's preference to locate in Roseville. Mr. Peterson advised that economic considerations indicated a preference to work within a 15 mile radius of the plant, and within their market area, providing as- phalt paving for major highway construction projects in the area, but most work consisting of parking lots, driveway contractors and City streets. Mr. Kittleson advised that the company had a good client base in metropolitan in- ner-city suburbs, and that they hoped to be in the City for the long-term, and to be a good corporate neighbor and blend into the community.
