PERTAINS TO CASE #3 REQUEST FOR CUP FOR COMPOST FACILITY Concerns expressed by various city and county staff and councilmembers: A suggestion was made that the biof'flter be a closed system. PZ Commissioners Deemer and Bawden visited a compost facility in New York. They walked on the biofilter and could smell nothing; they extracted woody material from the biofilter and there was no odor to it. Perhaps the CUP should just generally state that the biofflter must meet the approval of Anoka County and IPS can negotiate the need for a closed system with Anoka County. o If the biofilter does not function as promised outdoors, should the CUP require that it be moved indoors? What back-up system is in place to maintain negative pressure in the building when the garage doors are open? Garage doors are only open long enough to let trucks enter and exit. Doors are closed while vehicle is unloading. Dave Bawden visited a site and the plastic drapery between the compost mixing area and unloading area is very effective for containing odors in the mixing area; odors in the unloading are not that bad but there is a significant odor in the compost mixing area. The system operations could malfunction if there was a power failure -- perhaps a back-up generator should be considered. The existing soil berm and tree screen on the site should remain or be replaced with like material. Leachate from finished product and woody waste piles should be directed to a closed sump and collected for wansfer to a wastewater treatment plan. The CUP should specify the amount of the penalty for bringing uncovered loads onto the site. For instance, the rate will be twice that of a covered load. The City should be provided with monitoring and test results within 48 hours of requesting same. o Is the City assuming liability for establishing the amount of insurance to be provided by the permit holder. Mr. Goodrich states that the City is not assuming any liability by establishment of minimum insurance requirements; the City may be liable if proof of insurance is not required. Proposed Additions to Findings of Fact: Add a finding to indicate that the Site is owned by Waste Management of Minnesota, Inc. and that they support the application. Proposed Additions to Conditional Use Permit: 1. Add language to indicate that Waste Management consents to the CUP being issued to IPS for the use on their site. Add a signature block for Waste Management. 2. That the biofilter must meet the approval of all other permitting agencies.
