11. 12. 13. 14. 15. 16. 17. 18. That the primary concerns expressed by residents at the neighborhood meeting were screening of the treatment facilities, impacts on residential wells, noise from the air stripping operation and odors from the stripping operation. The Applicant has stated that they would plant pine trees and other species on the south and east side of the treatment facilities to supplement existing oaks. That the Applicant states that noise generated at the facility will be below state regulatory standards and that no odors are anticipated. That the Applicant has stated that their report "Aquifer Analysis" dated May, 1989, evaluated impacts of the pumping operation on groundwater elevations and concluded that no adverse effects were anticipated. The Applicant further states that if wells are adversely affected, WMMI will modify or replace the affected wells to maintain service for affected parties. That the City has not received a copy of the "Aquifer Analysis" report dated May, 1989. A feasibility study - Detailed Analysis Report was prepared by Foth & VanDyke and Associates, Inc. on behalf of Waste Management of Minnesota, Inc. (WMMI) for the Anoka Regional Sanitary Landfill, in accordance with a consent order entered into with the Minnesota Pollution Control Agency on May 30, 1985. The Consent Order required that a Remedial Investigation (RI), Feasibility Study (FS) and possible Response Actions be undertaken at the Anoka site. The purpose of these steps is to determine if a release or threatened release of hazardous substances exists at the Anoka site, and to develop and implement remediation strategies, if necessary. - An exposure risk assessment prepared for the "No Action" alternative in the Detailed Analysis Report concluded that if remediation were not undertaken, an unacceptable human health risk would exist from the ingestion of groundwater containing vinyl chloride and 1,2,-dichlorethane, and from the inhalation of vapors containing these two compounds. Therefore, the study proceeded with an evaluation of potential remedial alternative components. Work under the Remedial Investigation was completed in conformance with a Consent Order, an approved work plan, work plan addendums and MPCA approved Quality Assurance/Quality Control plans. Available records indicate that the majority of waste deposited in the landfill is mixed municipal refuse. During the initial period of site operation, a limited amount of what is currently classified as hazardous waste is believed to have been co-disposed with mixed municipal refuse (Remedial Investigation). 3
