5 TOTAL FACILITY General Facility History The initial operating permit for the facility was issued by the Minnesota Pollution Control Agency (MPCA) on April 13, 1970, to Bullert Construction Company for the operation of McLeod County Sanitary Landfill for disposal of approximately 15 million cubic yards of refuse. This permit was amended in 1983 for continued operation of the facility. The permit was reissued in 1993 to Sanifill, Inc. and McLeod Landfill, Inc. for a five-year period. Based on the site configuration as depicted in the 1993 permit application, the permit decreased the ultimate design capacity of the facility to approximately 8,290,888 cubic yards. As required by the Solid Waste Rules and the 1993 permit, the facility submitted a repermit application in January of 1998 to continue operation of the facility. The repermit application included some design modifications which also increase the ultimate design capacity of the facility. The design modifications in the application included 3:1 slope on the final cover system and participation in the Phase I leachate recirculation pilot program The MPCA has since issued a slope guidance document allowing increased final cover slopes at the facility and a guidance document for landfill leachate recirculation. Based on the MPCA's issuance of the new guidance documents regarding slope and leachate recirculation, the facility submitted a new permit application in August The MPCA issued a new permit on April 29, 2004, and modified (Major Modification) the permit on November 13, 2007, to allow for the construction and operation of the North Development Area for disposal of demolition/industrial waste The 5-year permit issued on April 29, 2004 and modified on November 3, 2007, expired on April 29, The permittee submitted a repermit application in October 2008 and has been allowed to continue operation of the facility under the expired permit. Minn. R allows a facility to operate in accordance with the terms and conditions of an expired permit. Hours of Operation The facility (Spruce Ridge Resource Management Facility (SRRMF)) is open for business (waste acceptance) between the hours of 6:30 a.m. and 8:00 p.m. Monday through Friday, 6:30 a.m. to 5:00 p.m. on Saturdays, and closed on Sundays. During business hours, operational controls shall be implemented to mitigate or otherwise minimize nuisance dust and noise impacts. General Facility Description The facility authorized by this permit include MSW disposal area (unlined closed landfill and open lined landfill), lined demolition/industrial waste disposal area, tire storage area, concrete, asphalt and wood material storage area, appliance and scrap metal storage area, and citizens drop-off area. Page 3 of 49

6 TOTAL FACILITY General Unlined Closed Landfill. The unlined closed landfill occupies approximately 42 acres of the facility. Solid waste was deposited in the unlined disposal area between 1970 and The unlined area received final cover in accordance with the MPCA closure requirements in The cover has provided the base grades for a larger portion of the lined landfill cells that have subsequently been constructed. The airspace capacity in the unlined landfill is approximately 2,072,700 cubic yards. This area is designated as Waste Activity SA001 under this permit. Lined Landfill. The current lined landfill includes Phases 1 through 8A. Phases 1 through 3 have been constructed on the side slope of the unlined closed landfill. Phases 4 through 8A were constructed on virgin ground. Although the majority of Phases 4, VII and VIIIA were constructed on virgin ground, a small area as piggybacked over the unlined closed landfill. Phase 4 (cells B and C), Phase 5 and Phase 6 were used for disposal of demolition/industrial waste. Phases 7 and 8A were used as bioreactor cell(s) for disposal of MSW and approved industrial and liquid waste. The future liner area, to be constructed, includes Phases VIIIB, IX, and X. The lined landfill has been designated as Waste Activity SA002 in this permit. Restriction on Disposal This permit requires the permittee to comply with Minn. Stat , which prohibits disposal of unprocessed metropolitan area MSW under certain circumstances when there is processing capacity at MSW processing facilities in the landfill service area. Requirements for restrictions on disposal are located in SA002, Specific Conditions within this permit. There is also a date requirement for submitting a compliance plan in the Required Actions and Submittals section of this permit. The facility has a citizens' drop-off area designed to allow for a safer means for individual citizen to drop off waste, keeping them out of the working face and away from the larger haul truck traffic. The drop-off area is located near the office area and consists of three 40 cubic yard roll-off containers which are emptied on a daily basis. Small MSW loads, appliances, electronics, tires and recyclables from individual citizen may be placed in these containers. This waste activity area is designated as TR001 under this permit. Demolition/Industrial Disposal Area. The facility accepts demolition/industrial waste for disposal. The demolition/industrial waste disposal area also referred to as the North Development Area has been designated as Waste Activity DD001 in this permit.
