5:00 p.mt, Monday through Friday and 7:00 a.m. - 1:00 p.m. on Saturdays. 18) That ~Pg has stated that the compost bays would be monitored for temperature, moiSl~e ~,Ontent, and physical appearance. 19) The ~llo~ving method will be used for compost production. The mixed materials will I~ 10aded into the ten concrete bays. Temperature and aeration cont~ls will main~ainiaerobic conditions and optimum temperatures during the composting proa~s. ',A series of blowers are mounted at intervals along the side of the outer bays.i Each bay will have five independently controlled aeration zones. The blow~rs .are controlled by an automatic temperature feedback system, as well as tim~m~, for forced aeration. The airflow moves up from the bottom of the bays via a syst¢~n of perforated pipes. Each blower is independently controlled allowing p~reei~ tetnperature management during the entire composting process. Auto~aatti: control of the aeration blowers is obtained by means of thermocouples perm~mefitly mounted in the bay walls. Data is fed to a programmable micro- prO~e~so~ which tums the blowers on and off. This system also maintains and records tei'nperature data for operation control purposes. Two I~S agitators will be used to process the material approximately once per day in eac~h bay. Material will remain in the bays for approximately 17 to 21 days. Fini,sOed inaterial will be removed once daily from each bay, it will be stored outside on an asphalt paved area. The product storage area is sized to allow for six monks of storage to enable the material to be stored through the winter months. 20) That ~.~PS has stated that they plan to use a portion of the compost material as soil enhaa~ement for landfill borrow areas or soil enrichment for completed portions of the pr~per~ owned by Waste Management of Minnesota, Inc. · [ 21) Wast~ M ,anagement of Minnesota, Inc. has estimattd that it could use all of the comPOst produced by the IPS facility for a minimum of 4.5 years. 22) That !PS has stated that tree prunings will be stored up to approximately 5,000 cubic ~ards of volume and then chipped with a wood chipper or chipped more often if appropriate, 23) That Sprfaee water run-off will be diverted to low areas within the Site and IPS has statedithat the existing Iow areas are large enough to accommodate spring snow melt. .~S ihas provided a grading plan with its submittal of November 24, 1993. 24) That I~S has stated that site access roads will be constructed. Access roads will be constr~cte~ on the interior of the si~.e. 25) That IPSstated that the facility will be secured with welded wire fence and gate alread~ existing on the site. 26) That r~o other conditional use permits for enclosed Compost facilities have been issued!in the City. 27) That I!?S has indicated that outdoor compost storage will occur on a hard surface pad of[ap~oximately 29,760 square feet. 28) That file average sidewall height of the proposed building will exceed 20 feet.
