I I I Council Meeting Minutes December 22, 1987 Fieski indicated staff's recommended three-inch surface to allevi- ate dust would cost $100,000 and there is not enough traffic to justify either the thickness or the cost. In response to Benke's question, Mattila stated no one from staff or the Planning Commission recommended a three-inch thickness. Waldis Erdmanis, Buck asphalt is produced and come a problem there is a through bituminous. Blacktop representative, explained how recycled, and stated if dusting does be- way to control it through chemicals or Mattila believes traffic over recycled asphalt material does pro- duce dust. Benke stated he was not as concerned with appearance as with whether or not there is sufficient traffic to generate dust. Blomquist noted the MPCA suggested an impervious layer on top of the site to prevent stormwater infiltration. Benke asked if seal coating would be considered impervious; Proper stated the city has used a lot of recycled blacktop, which is crushed to a Class V gravel specification, and. it makes a excel- lent road base. However, his experience is that it is very dusty (but maybe that would not occur in a parking lot situation) and has found that it is impervious (more so than a lime rock base). Benke stated if we have a minimum amount of rain it would generate a lot of run-off. Williams asked what kind of site preparation is done before the material is laid, and asked if it is so impervious that weeds would not grow through it. Fieski stated the MPCA is prepared to approve the site plan as proposed and has placed restrictions on the property to maintain the cover over the landfill, and to guarantee the runoff will go in a westerly direction, and believed nothing would grow through recycled Class V. Benke asked if seeds blown onto the site could be controlled or if the would germinate on the surface; Erdmanis stated blown seeds could be controlled with a form of weed control. In response to Williams' question, Erdmanis believed the material would be five inches thick. Gunderman indicated the Environmental Quality Commission had some concerns for this project at the December 9th meeting; the EQC and the applicant had dramatically different opinions regarding the composition of the landfill. Gunderman stated many questions were left unanswered and council/staff should know what the contami- nants are before approving a project on the site. Page 8
