Maplewood Landfill posts lower tonnage, $1.2M in host fees; cap and gas-collection work underway
Summary
Landfill staff reported 380,907 tons received year-to-date through June 2025, down from 449,037 the prior year, and $1.2 million paid in host fees; DEQ recently certified two new cells and a 15-acre final cap, and a gas-collection expansion is beginning.
Ben, landfill operations staff, reported that year-to-date through June 2025 the Maplewood Landfill received 380,907 tons, compared with 449,037 tons in the same period the prior year, a year-over-year decline of about 68,130 tons. "Year to date through June 2025, the total tons taken in were 380,907 tons," he said.
The facility has paid about $1.2 million in host fees through June, Ben said. He also updated the committee on recent permitting and construction work: DEQ inspected two new cells and a 15-acre final cap and issued certificates for both projects. "We did receive DEQ certificate for both projects, the two new cells as well as the cap," Ben said.
Operations staff described a gas-collection expansion that will add 15 additional gas wells plus six horizontal collection laterals; the team expects to begin construction of the next 15-acre final cap next month. Ben said the expansion and capping work will improve gas collection and site controls.
Committee members asked for updated GIS maps showing phases and the active fill area after reviewing an older aerial map. Members and staff discussed the site's filling sequence — currently progressing from south to north — and where operations would continue once the recently built cells are full. Ben said the site is operating in the mid-to-late phases and that timing for future areas depended on incoming volumes.
The committee also discussed how rail deliveries have affected fill rates and life-expectancy estimates. Members noted life-expectancy figures have ranged widely in past documents; Ben said the last commonly cited estimate he had heard was about 70 years but stressed that the number changes depending on rail and truck volumes. The committee asked staff to distribute updated maps and a clearer summary of active versus permitted acreage.
Next steps: staff will provide updated phase/GIS maps and continue routine DEQ reporting; committee members requested follow-up data on how rail volumes affect projected life expectancy and fill schedules.
