` Narrative for Ramsey County Interim Use Permit 515 Larpenteur Avenue West � Interim Use Permit Request Purpose and Background Ramsey County currently has between 2000 and 2500 tons of construction debris stockpiled on County land at Kent Street and Larpenteur. Ramsey County discovered construction rubble debris when excavating the Snelling Avenue pond as part of the County Road C reconstruction project The pond site is located in the SE corner of Snelling Avenue and County Road C. The purpose of the pond is to treat storm water runoff prior to discharge into the adjacent wetland. Since construction of the pond was a critical part of completing the project, and property for the pond limited, upon discovering the construction debris, the County had no choice but to excavate the material. The County believes that reusing the material by crushing and mixing it into useful material is the most economical and earth friendly solution. The debris contains concrete, bituminous, rock, and some metal pieces. The size of the material varies. The County desires to separate the metal from the debris and crush and mix the remaining material to make a blended and graded aggregate that could be reused for road building. The other option would be to haul it to a construction debris landfill which is expensive due to the hauling and dumping fees. Site Activity Proposal The County proposes to complete the crushing and mixing as soon as approvals are granted. The goal wiil be to complete the wark in late March, early April. The work will take a total of one week of which 2 to 3 days will be the actual crushing. The remaining time will be used to move in the portable material processing equipment, separate materials and then to demobilize. Once processed, the material will be hauled off site for reuse and the metal scrap material will be hauled to an appropriate disposal site. The site will be restored to the prior condition. The County will take measure to limit the dust and noise created by this activity. Since it is proposed to do this March/April, most residential homes will still have their windows closed. The work would only take place during the normal work week with hours of operation limited between 7am and 7pm, within the City's required times. Water will be used to control dust during the operation.
