Olmsted County plans to expand the capacity of its Kalmar Landfill Facility, located about four miles west of Rochester. The 160-acre facility includes disposal areas for construction and demolition waste, municipal solid waste, and ash produced from the Olmsted Waste-to-Energy Facility and Mayo Clinic medical waste incinerator. Olmsted County is proposing to increase the ash landfill capacity by five acres, which would extend its ability to accept ash by more than 30 years. The expanded capacity would be within the existing footprint of the facility.
The Minnesota Pollution Control Agency (MPCA) has prepared an Environmental Assessment Worksheet on the proposed expansion, which is required on this type of project. State agencies use an EAW to help decide whether a project requires a more extensive Environmental Impact Statement. The EAW describes the project’s potential effects on nearby land uses, geography, bodies of water or groundwater, wildlife and habitat, and historic sites. It also details air and vehicle emissions, dust, traffic, noise, and odors that the project might produce.
Olmsted County’s proposed expansion would include systems to line the disposal area, collect water running through and off the waste, and detect leaks, as well as a final cover design. The water collected at the landfill is stored onsite and then hauled to the Rochester wastewater treatment plant for proper disposal. The county also maintains a system of wells to monitor any impacts to groundwater.
The EAW is open for public comment through Dec. 4. View the worksheet for this project on the MPCA's Environmental Assessment Worksheet webpage or by contacting Kim Grosenheider (651-757-2170). Email or mail comments in writing to Kim Grosenheider, MPCA, 520 Lafayette Road N., St. Paul, MN 55155-4194 by 4:30 p.m. on Wednesday, Dec. 4.
