6.1. SR 07-20-1998City of ITEM 6.1. Memorandum TO: MAYOR AND CITY COUNCIL FROM: STEPHEN ROHLF, BUILDING & ZONING ADMINISTRATOR DATE: JULY 20, 1998 "~ SUBJECT: REVISION TO SOLID WASTE FACILTY BY ELK RIVER LANDFILL, INC. CU 98-17 REQUEST The Elk River Landfill is proposing to construct a new demolition debris cell at their facility. This proposal triggers a revision to the landfill's conditional use permit and solid waste facility license with the City of Elk River. The new demolition debris cell is proposed to be 24 acres in size. Approximately 18 acres of this new cell are proposed to be located on top of the solid waste in the original cell of the landfill, which is located within the Elk River city limits. A little more than 6 acres of the requested demolition cell will be new landfill area that extends into Livonia Township as well as Elk River. In addition to the new demolition cell, the required two year renewal of the Landfill's conditional use permit and solid waste facility license is also under consideration at this time. House keeping item, such as a new site manager at the landfill, will be addressed. The demolition debris cell request also requires revisions to the Minnesota Pollution Control Agency's (MPCA) and Sherbume County's permits for the Elk River Landfill. The City of Elk River, Sherburne County and MPCA cooperated on the review of the Landfill's request.

A memorandum from Matt Ledvina of B.A. Liesch dated, June 18, 1998, containing suggested changes to the landfill's current conditional use permit and solid waste facility license. · A revised conditional use permit and solid waste license for the landfill. Issues and Concerns Attached to this memo is a joint letter from MPCA, Sherburne County, and the City of Elk River, dated June 8, 1998, outlining staff's issues and concerns with the landfill's proposal. None of the government agencies listed take issue with what the landfill is requesting, but rather how it is designed. The new area of the landfill that is proposed to expand into Livonia Township is planned to have a liner underneath. This liner will add some benefits as far as the collection of landfill gas in this area. The concerns with the proposal mostly revolve around the disposal of demolition debris on top of the mix municipal solid waste in the original cell at the landfill. This cell is unlined and has contamination associated with it that is undergoing remediation. In the attached letter from Debra McDonald of USA Waste, dated June 17, 1998, Ms. McDonald indicates that the plans and specifications for the proposes demolition cell will be revised to incorporate staff's recommended changes. These revised plans have been reviewed and determined to be acceptable. The attached memorandum from Matt Ledvina of B.A. Liesch, the city's landfill consultants, lists other recommended changes that are needed to bring the landfill's current conditional use permit and solid waste license up to date. These changes are minor in nature and have been incorporated into these documents. fi\shrdoc\b&z\stever\camascup.doc Recommendation The property in Elk River proposed for the landfill's new demolition cell is already zoned Solid Waste Overlay District (SWOD) and is mostly devoted to landfilling at this time. Proper design of this proposed cell can reasonably address associated environmental concerns. The Planning Commission recommended approval of the landfill's request for a new demolition cell under the stipulations listed in the joint letter from MPCA, Sherburne County and the City of Elk River dated, June 8, 1998. These stipulations have been addressed in the landfill's revised plans and referenced in the attached permits from the city. However, there are still a couple of details regarding the revised drawings that need to be addressed. Staff will attempt to have these details worked out prior to the Council meeting. Further, the Planning Commission recommended that the proposed revisions listed in Matt Ledvina's letter dated, June 18, 1998 be incorporated into the landfill's conditional use permit and solid waste facility license. These attached documents reflect Mr. Ledvina's comments. The landfill's conditional use permit and solid waste license will receive an automatic review for renewal with public hearing in two years from the date the City Council acts on this current request (tentatively July 20, 2000). fi\shrdoc\b&z\stever\camascup.doc Minnesota Pollution Control Agency June 8, 1998 Debra McDonald USA Waste Services, Inc. 825 East 2nd Street Blue Earth, MN 56013 RE: Elk River Landfill, Application for Permit Modification Dear Ms. McDonald: The following comments are a summary of the concerns and requirements from the Minnesota Pollution Control Agency (MPCA), Sherburne County and the City of Elk River regarding your Application for Permit Modification, dated April 1998. 1. The final cover system shall be designed according the municipal solid waste (MSW) standards. It is noted that the liner and leachate collection system for the proposed demolition cell does not meet design and construction standards for MSW and/or industrial waste disposal sites. As a result, only demolition debris and new construction debris will be allowed for disposal in the proposed area. See Attachment A for definitions of allowable waste materials. o A liner system shall be required for the demolition debris horizontal expansion area and shall be required to have a minimum six inches of clay and a 40 mil flexible membrane liner. The clay shall have a maximum permeability of 104 crrdsec. See Attachment B for QA/QC requirements for liner construction. 4. The 906,300 cubic yards of air space capacity proposed for the proposed development shall be counted as a portion of the 4,926,200 cubic yards of"reserve capacity" for the site. The plan sheets shall be revised to show the development of the site in two-year phases. Development plans shall indicate the sequence of filling for each phase, access to the working face and placement of final cover. The engineering report shall be revised to include a narrative to describe how each development phase will be filled, how surface water will be managed and how vehicle access will be provided. The plan sheets and engineering report shall be revised to provide vehicle access for operation and maintenance of the new leachate management facilities, existing and future landfill gas (LFG) extraction system components and maintenance of final cover. 7. The post-closure operation and maintenance period for the proposed development shall be modified to cover 30 years. ' Page 2 June 8, 1998 o The engineering report shall be modified to include procedures which will be used to protect ihe barrier layer underlying the demolition debris during filling operations considering the physical characteristics of the waste material. 9. The plan sheets and engineering report shall be modified to indicate the management of LFG condensate in a manner consistent with that of MSW leachate. 10. The surface water management plan shall be modified to tie into existing and future surface water control features for closed portions of the west slope. Surface water ponding areas within the fill area shall be eliminated. The design of surface water control structures shall be modified t9 provide a continuous final cover system. 11. The proposed leachate management system shall be modified to eliminate potential problems with operation and maintenance. Specifically, the ieachate sump area and force main shall be designed to provide frost protection. 12. Final cover slopes shall be constructed with a maximum 4H: 1V grade in accordance with approved plans. All transition areas where slopes change grade shall not exceed 4H: IV. 13. The leachate collection and management system shall be operated to maintain a maximum head of one foot on the barrier layer for the liner. 14. A 200 foot buffer area shall be maintained between the waste and the property line. If compliance boundary wells are required beyond the property boundary, a variance from the Solid Waste Management Rules will be required. The May 21, 1998 technical memorandum prepared by Wenck Associates which provides supplemental design information shall be incorporated into the modified plan sheets and engineering report.

Box 490 Elk River, MN 55330 RE: Elk River Landfill - Request for Permit Modification Dear Gentlemen: I am writing on behalf of Elk River Landfill to respond to your June 8, 1998 letter which contained comments on the April 1998, Application for Permit Modification, submitted by Wenck Associates, Inc. All comments contained in the June 8, 1998 letter, have been addressed in a revised Application for Permit Modification, which was submitted to your offices on June 9, 1998. In addition, these comment responses, as addressed in the revised Permit Modifications, follow agreements reached in earlier telephone conversations and meetings where we were able to discuss your concerns. It is our understanding that all items, with one exception noted below, have been addressed in a manner which enables continued protection of the existing waste deposit and meets and exceeds regulatory requirements. Please refer to the revised Application for Permit Modification, dated June 1998 for detailed information. Comment #14 seems to reflect a misunderstanding. Comment #14 currently states the following: "A 200 foot buffer area shall be maintained between the waste and the property line. If compliance boundary wells are required beyond the property boundary, a variance from the solid Waste Management Rules will be required." From conversations and meetings with the MPCA, we believe Comment #14 was meant to have said the following: "A 200 foot buffer area shall be maintained between the waste and the property line, or beyond the property line if adequate easement(s) are in place. If compliance boundary wells are required beyond the property boundary, a variance from the Solid Waste Management Rules will be required." We understand Dave Lucas discussed this comment with Ms. Amy Hadiarus, MPCA Hydrogeologist, and she concurred with our interpretation. She indicated to Mr. Lucas she will forward a letter which will amend Comment #14 to reflect the above interpretation. Elk River Landfill is in discussions and is currently working with the adjacent northern property owner to acquire an easement beyond the property line. We are committed to obtaining this easement as part of the approval process for the proposed permit modification and believe this response satisfies the amended comment # 14. We appreciate your coordinated efforts on this project. Please call me with any questions. Sincerely, USA WASTE SERVICES, 1NC. Debra A. McDonald, P.E.
