Back in 2011, the Minnesota Pollution Control Agency (MPCA) approached the City regarding the need to consolidate waste and make repairs at the closed landfill that the State of Minnesota owns on Flying Cloud Drive in Eden Prairie. The landfill was owned and operated by BFI from 1970 to 1988. Soon after its closure the management and responsibility of the landfill went to the State. In fact, since 1994 the State has taken over 112 landfills throughout Minnesota as part of its closed landfill remediation program.
The Eden Prairie landfill project began in June 2013. Below is the detailed history of the project since its commencement as told to me through two emails by project manager Pat Hanson of the MPCA.

Rick- here is a short summary about progress at the site. Progress has been excellent at the site since construction started June 1, (2013). No major problems have been encountered and no delays other than a short shutdown this winter. Contractor has moved approximately 750,000 cubic yards of waste onto the new footprint of the site- this is 31% of the total waste expected to be moved. The old landfill was approximately 96 acres and we are reducing the size to approximately 56 acres. The waste that has been relocated has been covered by buffer soil. The goal is to have all of waste on the east half of the site relocated and covered with soil by this Spring to reduce the odor issue that the residents were experiencing last summer. There still will be odors as we work on the west half but the distance will help disperse the odor before reaching the homes. The contractor will start drilling the new gas wells on the east side this month and is expected to install the new cover system on the east side starting May 1st and having this work completed by late summer including seeding of grass. This summer the contractor will relocate the remaining waste on the west side and hopes to have that work completed by fall and start the final cover system on that portion immediately. We are expecting the final completion to be summer of 2015.
The quantity of waste is running a little greater than what our waste borings were showing and we are not getting as much compaction as expected so we need to find room for some additional waste. We will probably expand the footprint on the west side by five acres and increase the final height by 5-10 feet on the west side also to take care of the extra waste. There will be no noticeable change (very slightly taller) to the final look of the site to the residents on the east side with either of these changes.
All parties have been pleased with the progress and are hoping the project continues at the same pace. The biggest complaint has been the odors from last summer- the odor can be bad on certain weather conditions but with the waste relocation work being completed on the east half by May the residents should not be impacted like last summer.

Rick- Progress has been excellent since my last update. Our goal was to have the east half of the landfill completed and seeded by July 1 and we accomplished that. The east half was seeded and the contractor watered the seedling so by August 1st that side was totally green with grass. The contractor has been relocating waste in the southwest and north side this summer and has relocated approximately 1,000,000 yards of waste in those areas this summer. He estimates he will have the remaining waste relocated and covered by buffer soil by the end of the year. This winter he will install the remaining gas wells on the west end and expects to install the plastic liner in May and have all the components of the liner system installed on the west half by mid summer 2015 and we are expecting final completion of the project in late summer 2015.
I have received very few calls this summer from residents as once the east side was seeded the disruptions to their lives have been reduced greatly. There is still some site work to be done-storm water, final grading of buffer areas but the major work is complete for them. There are still odors from the work on the west side but the impact to Allied Waste is offset from the smells from their transfer station operation and I have not heard from them.
We have made some minor adjustment to the final design grade and shape on the west side as I indicated in my last message- the design changes are so slight most people would not notice the change from the original design.
Overall comment is the project is going great, the residents on the east side are generally happy, and we expect to have the total project completed by this time next year. Thanks, Pat.
As you can see, the project will be completed next summer. I have had the opportunity to talk with a few of the affected residents over the past two years and can attest to the accuracy of Pat’s update — from the occasional odors to the high quality of the work. We all agree that the end result will be an improvement.
