6.1. SR 11-19-2001C~ty ~ MEMORANDUM Item ~ 6.1. TO: Mayor and City Council FROM: DATE: Steve Rohlf, Building and Zoning Administrator November 19, 2001 SUBJECT: Modification to Elk River Landfill's Conditional Use Permit and Solid Waste License to Authorize a New Demolition Disposal Area and an Encroachment into an Existing Buffer Area/P.H. Case # CU 01-35 Request The Elk River Landfill is requesting a modification to their existing conditional use permit (CUP) and solid waste facility license (most recent renewal of both was May, 2000) to allow them to dispose of demolition debris over the top of an existing mixed municipal solid waste (MSW) cell. This request necessitates a modification to their grading plan in the area of the proposed demolition debris cell. The modification includes changing the existing 5 to 1 slopes in this area to 3 to 1 slopes, which is consistent with the slopes to the south of the proposed demolition cell and encroaching on the buffer area adjacent to the City's Railroad Hiking Trail. The additional encroachment is due to the slopes and berms associated with the proposed demolition cell. The actual demolition debris will not be deposited any further into the buffer area than where the MSW is currently located. The property affected by this request is already zoned Solid Waste Facility Overlay District. Attachments ~ A vicinity map showing the location o£ the Elk River Landfill ~ A letter dated October 18, 2001, from Matt Ledvina, Environmental consultant for the City of Elk River. ~ The current Landfill CU.?

A Cross Section showing the proposed grade changes, dated October, 2001. · A landscape plan, dated November 15, 2001. Review of Issues Specific to the Request )~ Shoreland District - For over a year, the Elk River Landfill has struggled to gain approval of an expansion to their demolition debris disposal area in Livonia Township, which still has not been approved. One of the issues that surfaced with this request is that Sherburne County zoning requires landfill's to be located in industrial zones. Apparently, industrial uses are not allowed within the Shoreland District of a Natural Env. ironment Lake under Minnesota Rule 6120.3200. Rice Lake, adjacent to the west of the Landfill, is a Natural Environment Lake. The Shoreland District for a Natural Environment Lake is 1,000 feet from the ordinary high water mark, therefore, industrial uses are not allowed within 1,000 feet of Rice Lake. The property included in the Landfill's request in front of the City of Elk River also falls within the Shoreland District for Rice Lake. As defined by the city's Shoreland Management Ordinance (adopted from the state's Model Shoreland Ordinance) an industrial use is: "The use of land or building for the production, manufacture, warehousing~ storage, ortransfer of goods, products, commodities, or other wholesale items." Landfilling does not necessarily fit this definition. Unlike Sherburne County, the City of Elk River does not require that landfills be located in ind, ustrial zones. The Legislature of Minnesota has delegated responsibility to the local governments of the state to regulate the subdivision, use and development of the shoreland of public waters (M.S. 462). The city previously zoned the Landfill's property to Solid Waste Facility Overlay Zoning District, in which landfills are a condition use. Section 904.06 (2) (B) of the city's Shoreland Management Ordinance states: "All Permitted, Conditional and Prohibited Uses as specified by the applicable underlying Zoning District shall apply". ,~ The Shl' oreland Management Ordinance does not so much dictate what land uses go where, but rather how land uses affect the public water. The publication A Technical Report on Managing Nonconformities in the Shoreland Management District states: "Zoning controls regulate the location of underlying land uses. The shoreland standards focus primarily an the manner of use ~. e. dimensional standards) to reduce the potentially harmful effects on thepublic water of overcrowding and poorly planned development of shoreland areas, to maintain property values, and to preserve the natural characteristics of the shoreland and adjacent water areas". Landfills are an interim use, similar to mining activities, which are allowec~'in the Shoreland District of a Natural Environmental Lake. If done appropriately, in the long term the Landfill will be a grassy slope with no negative affect on Rice Lake. In addition to the normal seven standards for reviewing a conditional use permit found in Section 900.42 of the City of Elk River Code of Ordinances, the city needs to apply "Evaluation Criteria" for conditional uses found in 904.08 (7) of the city's Shoreland Management Ordinance, to ensure the protection of Rice Lake. It is staff's interpretatio~ that the city does have the authority to determine the type of land uses in a Shoreland District and that a landfill can be considered. Dave Hills, Regional Hydrologist for the Minnesota Department of Natural Resources agrees with this interpretation. Technical Issues- Matt Ledvina's attached letter, dated October 18, 2001, addresses the adequacy of the Landfill's proposal on a technical level. The Landfill's proposed 3 to 1 slopes for the demolition area, which are consistent with the cells on either side of it. Other technical concerns, such as storm water management and protection of the cap over the existing MSW cell have been considered on a staff level. If this request is approved, the recommendations contained in Mr. Ledvina's letter should be made conditions of that approval. Screening and Buffering - Besides the interpretation of the Shoreland Management Ordinance, the most critical issue involved in this request is screening and buffering. The disposal of demolition debris is not allowed by state rules within 50 feet of a property line and the disposal of municipal solid waste is not allowed within 200 feet. The city's permit is somewhat different in that it requires that a 200 foot buffer strip remain free of the disposal of MSW, demolition debris and associated slopes and ber,,ms. The purpose of this buffer is an attempt to preserve adjacent property values and natural amenities by taking advantage of natural screening and buffering. The city's buffer also leaves an area free of landfill activities so that things like monitoring wells can be placed on the landfill property. Through previous approvals, the Landfill has already been allowed to encroach on the 200 foot buffer adjacent to the location of this current request. The city's Railroad Hiking Trail is located to the west of the Landfill, where this expansion is proposed. Because of how close the historic waste fill limit is to the city's property in this location, the city has agreed to allow monitoring wells on its property. Due to it being in the proximity to the Railroad Hiking Trail, the Park and Recreation Commission has been asked to comment on this request. They believe that it is critical for the Landfill to demonstrate that the hiking trail will be better screened after the work under this proposal is accomplished than it was before, since the advantage of distance from the proposal will be sacrificed. The Park and Recreation Commission did not review the actual screening plan proposed by the Landfill, but the attached landscaping plan does reflect the details recommended by the Planning Commission. Other Landfill Issues When a request is made to modify an existing CUP, all pertinent issues regarding the subject operation are up for consideration. The following are ongoing issues that the Landfill and staff have been dealing with since the last renewal of their permits: Fires in existing demolition area- The Landfill first reported a hot spot (fire) in their existing demolition disposal area on the north side of their operation in the spring of 2000. Landfill fires can burn below the surface and, therefore, be difficult to squelch. This fire was smothered with earth and assumed out. A second fire, or possibly a flare up of the same one, sprang up in this demolition area this past summer. The introduction of oxygen due to mining recyclables in the demolition area may be one contributing reason for the fires. The Landfill has been required to install heat sensing probes to get an exact location of these fires to aid in suppressing them. Staff is not recommending adding conditions to the Landfill's Cup or license due to this issue. The existing language is adequate and it is a matter of enforcement. Litter- Since their last renewal, the Landfill has received a Notice of Violation from the Minnesota Pollution Control Agency (MPCA) regarding daily cover last summer. Daily cover, a minimum bf six inches of soil placed over the days refuse, is required to keep the refuse from blowing away and becoming litter. This was an operational problem that was apparently corrected since. In addition to the daily cover, the Landfill is required to erect temporary fencing adjacent to active areas to control litter and they are to inspect all trucks leaving the facility to ensure they are free of debris prior to leaving their site. As a last resort to control litter, the Landfill's CUP and license requires that they engage in routine litter removal along Highway 169 for ½ mile on either side of their entrance and from other areas adversely affected a minimum of once per week. Even with these controls, litter is still the number one complaint received by she city concerning the Landfill. Staff is not recommending additional permit language regarding this issue. Again, it is a matter of enforcement. Staff recently requested that the Elk River Police Department step up patrols in this area and ticket trucks with leaky loads (debris blowing off of them). Contamination - Controlling contamination from the original unlined cells prior to it leaving the Landfill site is the city's major concern. The active gas venting system installed at the Landfill is apparently doing some good in this regard. City staff will continue to monitor the ~'ituation to discern whether or not this remedial action is adequate. Two specific areas of contamination are of immediate concern. One is in the northeast corner of the Landfill where monitoring wells showed contamination extending close to the Landfill's property line. A change in the gas venting system in this area seems to have brought the contamination in this area under control. Contamination levels in the monitoring wells in this location are now below MPCA's intervention limits. The second area is on the west side of the Landfill where an apparently isolated plume of contamination is rapidly approaching the Landfill's property boundary. The Landfill is cooperating with staff to aggressively find a solution to neutralizing this contamination. Existing permit language is adequate to address the issue of contamination, therefore, staff is not recommending any changes. Safety - Due to the nature of landfill operations, safety is on ongoing issue. For example, the Elk River Landfill recently moved their scale house further back into their property to avoid waiting trucks stacking onto Highway 169. Waste Management has recently suffered a number of fatalities at their facilities throughout the nation. This has prompted Waste Management to develop "New Disposal Area Safety Rules and Procedures". Fairly recently, there was an accident at the Landfill where a large truck with it's box high in the air dumping it's load tipped over on someone. This caused the city to add a section in the Landfill's license and CUP titled, "Small-Load Dumping Site". This section requires separate areas for residents and commercial haulers to unload their garbage. The city's permits also contain language regarding safety equipment at the Landfill and training. Staff is not recommending that additional language be added to the Landfill's permits at this time, but will consider this again during their next renewal. Next Renewal - Staff is recommending that this review does not replace the Landfill's next permit renewal, which is scheduled in May of 2004. Staff's main rationale for this is that the Landfill is required as part of their next renewal to develop an end use plan for their property. The Landfill is prematurely in front of the city due to their need for additional area to accommodate demolition debris disposal. They are not prepared at this time to address the issue of an end use plan. It behooves the city not to rush this process in the hopes of gaining a better product. Leachate Recirculation Leachate, made up of mainly rainwater, is the contaminated liquid generated by landfills. The Landfill is proposing to collect this leachate in a series of pipes and recirculate it through the refuse. There are a couple of advantages to this process: · Recirculating leachate makes a landfill a bioreactor. Adding liquid speeds up the decomposition of refuse verses the conventional practice of locking it up in a dry tomb. One major concern with landfills is the life expectancy of the liners underneath them, which keep leachate from entering the ground water below. Speeding up the decomposition time of refuse reduces this concern by neutralizing certain contaminates before the liner's usefulness is in question. · Recirculating leachate causes refuse to settle more, allowing for more capacity on the same footprint. This consequently reduces the need for new landfill space. Differential settle at landfills is also a problem. After a landfill is closed you don't want water setting on top of it and potentially creating more leachate. Leachate recirculation helps with getting this settlement over before a landfill is closed. · A side benefit to leachate recirculation is that it speeds up the production of landfill gas, making for more efficient energy recovery (the landfill gas is being converted tt~ electricity). Sherburne County has already approved leachate recirculation at the Elk River Landfill. The city of Elk River also approved it as part of the Landfill's last renewal. This issue only awaits approval by the Minnesota Pollution Control Agency 0VIPCA) to be put into practice, which is anticipated prior to the next renewal of the Landfill's city permits. Criteria for Review Section 900.42 of the City Code of Ordinances - The city shall recommend a conditional use permit and the Council shall order the issuance of such a permit only if it finds that such use at the proposed location: i. Will not endanger, injure or detrimentally affect the use and enjoyment of other property in the immediate vicinity or the public health, safety, morals, comfort, convenience or general welfare of the neighborhood or the City. ii. Will be consistent with the comprehensive plan. iii. Will not impede the normal and orderly development and improvement of surrounding vacant property. iv. Will be served adequately by and will not adversely affect essential public facilities and services including streets, police and fire protection, drainage, refuse disposal, water and sewer systems, parks and schools; and will not, in particular, create traffic congestion or interference with traffic on adjacent and neighboring public thoroughfares. v. Will not involve uses, activities, processes, materials, equipment and conditions of operation that will be detrimental to any persons or property because of excessive traffic, noise, smoke, fumes, glare, odors, dust or vibrations. vi. Will not result in the destruction, loss or damage of a natural, scenic or historic feature of major importance. vii. Will fully comply with all other requirements of the City's Code of Ordinances, including any applicable requirements and standards for the issuance of a license or permit to establish and operate the proposed use in the City of Elk River. Section 904.08 (7) (A) of the city's Shoreland Management Ordinance- The following additional evaluation criteria and conditions shall be considered in evaluating conditional use permit requests within shoreland areas and a thorough evaluation of the waterbody and the topographic, vegetation, and soils conditions on the site shall be made to ensure: i. the prevention of soil erosion or other possible pollution of public waters, both during and after construction: ii. the visibility of structures and other facilities as viewed from public waters is limited. iii. the site is adequate for water supply and on-site sewage treatment; and iv. the types, uses and numbers of watercraft that the project will generate are compatible in relation to the suitability of public waters to safely accommodate the'~e watercraft. Findings/Recommendation MPCA has already approved the request by Elk River Landfill to add demolition debris over cell DC-3. Sherburne County has indicated that they will also approve this request, but are waiting for the City of Elk River to react to it. The Planning Commission found that the Landfill's request met the seven standards listed above for a conditional use permit and the four evaluation criteria list in the city's Shoreland Management Ordinance. Therefore, the City of Elk River Planning Commission is recommending approval of the modification to Elk River Landfill's Solid Waste Facility License and CUP to allow demolition debris to be deposited over MSW cell DC-3 under the following conditions: ,. 1. That this approval is conditioned on the recommendations contained in Matt Ledvina's letter, dated October 18, 2001. That Sections 2.) (03) (b) of the Landfill's CUP and Solid Waste Facility License be amended to read: "The demolition debris landfill cell DC-3 shall be located and operated as shown on the June 2001 Permit Application and August 2001 revisions submitted by the Permittee with city staff approving and having the authority to make decisions on the technical issues involved." That three rows of spruce with ten feet spacing between rows and ten feet spacing between trees in each row shall be planted on the city's property in areas adjacent to the proposed demolition cell where no trees currently exist. Other vegetation, such as bushes, shall be planted in these areas as proposed by Landfill. Further, that spruce shall be planted on the Landfill's property at the base of the slope along the entire length of the new demolition debris cell to help screen the operation during the winter. Lastly, that the Landfill provide the city a plan depicting these requirements, prior to the Elk River City Council acting on this request. 4. That this current amendment does not replace the Landfill's requirement to~.renew their Solid Waste Facility License and CUP in May of 2004. Case Number: Location Map CU 01-35 Elk River Landfill N October 18, 2001 Mr. Steve Rohlf City of Elk River 13065 Orono Parkway Box 490 Elk River, MN 55330 RE: Elk River Landfill-CUP Amendment Dear Steve: This letter is sent to transmit my comments regarding the Conditional Use Permit (CUP) amendments which have been requested by Elk River Landfill (ERL) and Waste Management, Inc. (WMI) in their application of September 21, 2001 and supplemental information dated October 16, 2001. As you have requested, I have also reviewed the conditions of the CUP to determine if any other changes are appropriate from a technical perspective. The major revision to the site development plan is the establishment of demolition waste disposal cell, DC-3, over previously closed mixed municipal solid waste cells 2 and 9, as well as a portion of cells 3. This development will have several beneficial aspects for the site. There has been significant settlement in this area of the site and surface water drainage has been adversely effected. Refilling this area will correct the settlement and will eliminate the need to transition the waste sideslopes in this area from existing 5:1 to future 3:1 for completion of subsequent waste cells in the southern portion of the site. "surface Water - The existing final cover system for Cells 2,3 and 9 contains water piping within the drainage layer along the existing benches. It will be necessary to locate this piping and abandon or remove it to prevent the flow of leachate through the piping and potentially beyond the cell DC-3 boundaries. The surface water runoff.-pond, P-l, located immediately west of the proposed DC-3 cell has been [econfigured and decreased in capacity to accommodate the construction and grading for the leachate containment system. The surface water routing for the final contour plan has been modified to correspondingly direct a large volume of surface water to the ponds located on the east and south sides of the fill area. A 24-inch culvert serves as an overflow outlet for Pond P- l. The construction plans should be developed to show the placement of rip-rap and other erosion control measures at the inlet and outlet of the 24-inch culvert. Leachate Management - The engineering design considerations for the construction of the new demolition cell are presented as a concept plan. Construction plans will need to be developed to account for detailed site conditions related to the replacement of the 10,000 gallon with a 30,000 gallon tank as noted on the engineering plan. The details for installation of the ENVIRONMENTAL.

Landfill Gas System - There are at least six LFG extraction wells within the fill limits of cell DC-3. The engineering design report indicates that the wells will be extended vertically as the filling progresses. Demolition wastes must be placed carefully to ensure that the wells are not damaged. I reviewed the CUP for items that might warrant change. If the council authorizes the requested amendment, the language in section 2.) (03) (b) should be modified. The reference should.be changed to read: "The demolition debris landfill cell DC-3 shall be located and operated as shown on the June 2001 Permit Application and August 2001 revisions submitted by the Permitee and reviewed by City Staff." I did not see the need to change any of the other specific conditions in the CUP. Other issues for WMI and the landfill can be addressed within the existing framework of the CUP and License. Please contact me if you have additional questions or comments. My direct dial phone number at ERG is 612-339-2316. Thank you. Sincerely, Matthew L. Ledvina, P.E.

From: Date: Re~ Steven Rohif, City of Elk River Planning and Zoning Debra Dehn, Elk PJver Landfill Manager Matt Ledvina, ERG 10/16/01 Elk River Landfill - Request to Amend the City of Elk River Conditional Use Permit BACKGROUND. Elk River Landfill (ERL) is requesting to amend Section 2.03, of the current City of Elk River C, onditional Use Permit_ The current Conditional Use Permit was issued in May of 2000 and provided approval of the January 14, 2000 repermit application pacl(~je developed by Wenck Associates. The repem~t application package consisted of an Engineering Report and Plan Sheets, which described the continued development of the landfill utilizing the following updated technology: 1) 3:1 final contour slopes over the remaining undeveloped area; 2) Increased height of remaining undeveloped perimeter berm; 3) Installation of leachate recirculation system; and 4) Surface water drainage and sedimentation improvements (within the buffer zone). The January 14, 2000 Final Contour and Grading Plan as previously submitted and currently approved under the City of Elk River Conditional Use Permit is attached. DESCRIPTION OF REQUEST ERL is requesting to amend Section 2.03 of the existing Conditional Use Permit to provide for development of an additional demolition and construction debris disposal area, known as DC-3, over the top of the previously dosed municipal solid waste (MSW) cell on the west side of the landfill. The development of the DC-3 are~ with a capacity of 620,000 cubic yards, is necessary to provide for immediate disposal of demolition and construction debris. The disposal airspace in the designated demolition and construclJon debris disposal areas, known as DC-1 and DC-2 on the north edge of the facility, has been rapidly consumed over the last few years and these areas are now full. Construction and demolition debris matedal may be placed in the ERL munidpal waste cells, however, this matedal consumes critical MSVV airspace which should be reserved for MSVV. As wel!, when demolition and construction debds is placed in the MSW cell, the haulers are required to collect and pay additional fees on the matedal as if it were MSW. As designers reviewed options for development of the additional demolition and construction debris disposal area, the middle west side of the landfill or the "transition area" came into discussion. This area was previously closed with an MSW cap at 5:1 or 20% sideslopes. Over time, the area has settled, creating sags which hinder proper surface water drainage. At the previously constructed 5:1 slopes, the area was. shown as an odd transition zone sandwiched betv~n the nor,hem demolition area with approved 3:1 slopes, and the southern continued MSW cells also approved for 3:1 slopes. The approved January 2000 plan sheets show the transition area and final contour configuration. · Page I The proposed DC,-3 design provides for the disposal of demolition and construction debris atop the existing landfill within the transition zone, bdnging the area up to a 3:1 grade, consistent with the northern and southern areas of the landfill. This will not only eliminate the surface water issues over this area, but will also provide for a better overall final contour configuration of the entire western side of the landfill. The DC-3 area will be final covered with an MSVV cap, as ulflized over the rest of the ERI_ Although not required by Minnesota Solid Waste Rules, the proposed DC-3 design includes provisions for leachate management and collection. Leachate would be contained behind a lined berm, which would be constructed at the toe of the existing final cover. Leachate would be pumped from a sump into a leachate storage tank. The proposed berm would be constructed such that no additional waste would be placed outside the existing waste footprint. The DC-3 proposal does not extend the waste fill boundaries for the site. The attached grading and final contour plans show the location of the proposed DC-3 development. ERL provided detailed engineering plans to the City of Elk River, Sherbume County and the MPCA in the spdng of this year. ERL met with representa~ves of each ~organization to address specific engineering items to arrive at the current proposal, dated July 27~', 2001. The MPCA has public noticed this proposal, as well as the January 2000 repermit application and anticipates delivering a new permit to ERL by the end of October. Sherbume County an~dpates a st. afl revision to the County Ucense, with subsequent board approval. Pending City of Elk River Approval and favorable weather, ER.[. antidpates construction of the area by December 1. BUFFER/SCREENING CONSIDERATIONS As mentioned above, the DC-3 ama does not increase the waste fill footprint of the site. There will, however, need to be grading at the toe of the slope for the DC-3 berm. As well, as the rest of the site progresses in accordance with the approved January 2000 repermit plans, there will need to be grading and shaping of landfill berm sideslopes, extension of the sedimentation basin on the west side of the landfill, and the construction of access roads. The attached air photo shows the existing vegetation coverage elong the western side of the landfill. Tree loss can be viewed by overlying the proposed future development activities over the photo. ERL acknowledges the impedance saving and maintaining as many trees as possible and is very conscience of the need to screen the landfill from the trail users. ERL welcomes the opportunity to work with the City and/or the Trail Group to develop an acceptable plan, which would likely include .the placement of conifers along the west and south slopes of the sedimentation ponds (see attachment screening plan). · Page 2 O00gt,~ N -- 80P d ONIN::I::I~OS O~SOdO~ld ~)NIN:~:~IC)S PROPOSED - SCREENING PROPOSED SCREENING PROPOSED ACCESS TANK ELK R I VER LANDFI~ EASEMENT AREA 'X SWALE 039.3"% ~' / --248000 WOv ~..o fl.

To accomplish this, the plan calls for maintaining and enhancing the efficiency of existing trees and to improve efficiency of tree row in collecting blowing debris and improving aesthetics. Plant materials will provide year-around buffering and have year around foliage. Another objective is to establish a long-term buffering along the west edge of the landfill. Low maintenance and fast-growing tree species would help maintain tree rows that already exist and provide added windbreaks to voided areas of trees. Screening Plan Design Align 1 row of tree plantings and 1 row of shrub plantings along voids of trees on the west side, to include property owned by the City of Elk River. A selected spruce species will provide year-round foliage and a large, dense canopy to improve aesthetics and collect debris. Spruce plantings will be spaced approximately 30' apart. Planting stock: will be either potted or B & B with approximately heights at 5-fi. Recommended spruce include Norway spruce, white spruce or approved species. Align 1 row of dogwood variety adjacent to spruce. Dogwood is shade tolerant, have a self-suckering ability to spread and will provide a dense, ground level buffer. Space dogwoods approximately 5 feet apart. Recommended planting stock is barefoot in sizes of 18" up to 30". Other shrub species to consider include ginnala maple, viburnum varieties such as nannyberry, or false indigo. This screening plan is in correlation with Sherburne County's screening plan. Design Elk River Landfill welcomes the opportunity to work with the City and/or the Trail Group to develop an acceptable design, which would likely include the placement of conifers along the west and south slopes of the sedimentation ponds.
