Ash Landfill

The Pope/Douglas Ash landfill began receiving ash from the Pope/Douglas Waste to Energy facility in 1994. The ash landfill was designed as a hazardous waste landfill even though the ash that is disposed of in the ash landfill is not considered a hazardous waste.

The liner system used at the ash landfill is designed to capture all of the rainwater that enters the landfill cell. The captured water (which is called leachate) is then pumped to a holding tank. The leachate is then trucked back to the waste to energy facility to be reused as quench water in the ash conveyors of the waste to energy facility. Excess leachate is hauled to the waste water treatment facility in Fergus Falls.

The liner is actually a four layer system. First is a four foot layer of compacted clay. On top of the clay is a 1/8 inch thick layer of HDPE plastic with the seams welded together to produce a continuous sheet under the ash. On top of the 1/8 inch thick plastic layer is a 1/4 inch layer of geotextile HDPE plastic mesh and on top of the mesh is another layer of 1/8 inch HDPE plastic sheeting welded together to form a continuous piece of plastic. The reason for the 1/4 inch plastic mesh, is to create a gap between the two 1/8 inch thick layers of plastic that we can monitor to see if there are any leaks in the top 1/8 inch thick layer of plastic. On top of the top layer of plastic is 1.5 feet of sand, and finally on top of the sand is the ash. The sand layer, on top of the plastic layer, is actually used as a way for any leachate that has percolated through the ash to migrate to a collection sump and be pumped to the holding tank.

Groundwater, from under the four layer liner system, is also collected and pumped to the holding tank. The groundwater is sampled on a quarterly basis to ensure that there are no leaks in the liner system. There are fifteen monitoring wells at the ash landfill site. The wells are sampled to verify that there are no leaks in the liner system that would contaminate the groundwater at the site and to study any environmental impact the ash landfill itself would have on the water table. To date, there have been no issues of contamination at the ash landfill site.

In 2006, Pope/Douglas Solid Waste Management did receive a variance from the Minnesota Pollution Control Agency (MPCA). This variance allows us to dispose of the one inch and smaller screenings from our Material Recycling Facility (MRF) at the ash landfill site. So the only two items that can be disposed of at the Pope/Douglas Ash Landfill site are ashes from our waste combustors and fines from our MRF.

The Pope/Douglas Ash landfill is on a 40 acre site that is 18 miles west of Alexandria. The 40 acre site is designed as a four cell site. Our annual survey during the fall of 2012 showed that at the current rate of filling, we have 70 years of life left in the four cell, 40 acre site.
