5.2. PCSR 08-24-2004 ITEM it 5.2. City of Elk River MEMORANDUM TO: Planning Commission FROM: Rebecca Haug, Environmental Technician eria- DATE: August 24, 2004 SUBJECT: Conditional Use Permit for Mineral Excavation by Schuer, Inc. Inc./P.H. CU 04-23 Request: Schuer,Inc.has an existing mining permit that allows them to mine 14.81 acres of a 66.06 acres site. They are requesting approval to mine an additional 5.5 acres of the same site. This operation includes periodic crushing of gravel, but not washing. The additional 5.5 acres are proposed to be excavated 15 feet below the ground water elevation using a dragline. The site will not be dewatered to accomplish this. The site was not included in the City of Elk River's 1994 Environmental Impact Statement(EIS)on Mineral Excavation,but a discretionary Environmental Assessment Worksheet (EAW) was completed for the original request. Additional environmental review is not required. All of the 66.06 acres site is already zoned Mineral Excavation Overlay Zoning District. A request for mineral excavation by J &B Mining is also on the Planning Commission's agenda for this meeting. Although the two requests are separate, the restoration (final contours) of the sites and wetland mitigation do tie together. Further,gravel from the J&B Mining site will be hauled through the Schuer site to Elk River Bituminous. To keep this haul route open, Phase 4 of the Schuer site (the current 5.5 acres request) will is not be mined or restored for 5 to 10 years. Attachments: Included with this memo is: ➢ a vicinity map, ➢ a Conditional Use Permit Application Submittal letter, dated March 29, 2004, ➢ A letter dated,July 28, 2004 from the city's Environmental Consultant, Matt Ledvina, regarding groundwater monitoring and the proposed environmental spill plan, ➢ a development plan, which shows the proposed final contours for the additional acreage, ➢ staff memorandum on Wetland Conservation Act, and • a proposed Conditional Use Permit (CUP). Issues: Traffic - The gravel mined from the site is currently delivered to the Elk River Bituminous site via an easement across private property owned by Aggregate Industries. Traffic from the new area(Phase 4)will be accommodated the same way. Section 10 of the attached CUP has additional stipulations on traffic. Groundwater - Mining into the groundwater raises additional concerns. Matt Ledvina, City Environmental Consultant, addresses these concerns in his attached letter. Environmental Spill Plan The petitioner's Environmental Spill Plan will be revised to address Mr.Ledvina's issues, e.g. identifying refueling locations. Ground Water Monitoring Plan The Ground Water Monitoring Plan will be revised to include monitoring for pH, temperature and conductivity as well as Diesel Range Organics. Staff does disagree with Mr. Ledvina regarding monitoring all three wells at the site, however. Staff recommends that only the down gradient well located in the southeast corner on the site be monitored(MW 1). Incidents of contamination will be known. Section 17 of the attached CUP has a condition that allows additional wells and additional testing events, if needed. National Pollutant Discharge Elimination System (NPDES) The existing NPDES permit for the operation that has been revised and approved by the Minnesota Pollution Control Agency,which includes an updated Storm Water Pollution Prevention Plan(SWPPP)that reflects the proposed Phase 4 mining area. Wetlands-The Technical Evaluation Panel,charged with reviewing wetland issues for compliance with the Wetland Conservation Act is recommending approval of both the wetland impacts and wetland mitigation for the operation. Section 9d of the attached CUP requires monitoring of the wetland mitigation, which is to be secured by a letter of credit. A dollar figure to cover the restoration has yet to be determined. The proposed wetland restoration plan is based on the premise that the groundwater level incurred is not a perch water table.If information to the contrary is discovered, the Operation shall cease until new mining and restoration plans are submitted and approved by the City. Setbacks-Normal setbacks for a mining operation in the City of Elk River are 50 feet, but they can be increased if the pit is adjacent to a sensitive land use or reduced if adjacent to another mining operation. The new area proposed to be mined,Phase 4,is bordered on the north by Ernie Toth's property,which is currently being mined by Bauerly Bros. Staff is recommending the petitioner is allowed to mine to the property line and that this area is restored to 4 to 1 slopes. It may be a long time ' before the Toth's property is mined or it may never be mined. Either way the 4 to 1 slopes suffice. To the south and east, Phase 4 will tie into the proposed J & B Mining operation and restoration. To the west, Phase 4 ties into Phase 1 of the Schuer operation. Recommendation: Staff is recommending approval of this request under the conditions contained in the attached conditional use permit. Representatives of Schuer, Inc. are in agreement with those conditions. ri ii \\, , , , _____,____ ______±_, 1 , , , ir r; i ---- I SITE Y " L A C 1" Et " �Ii• IY q, it t. rrit i L 5 .i ii it I\, c) zlim ExuE 1 ♦u lit 1 i :\\ rr 1 Al ,L 1400 i E " LYI i I " 5 E A wTM j I I " TILLS j 7 Diu .� 1itI! k3• �I I , Location Map *vier N 4 Case Number CU 04-23 SCHUER www.liesch.cam - 1.1 ;ATE nECLI: oar LIE CH LIESCH ASSOCIATES, INC. 13400 15TH AVENUE NORTH MINNEAPOLIS, MN 55441 763/489-3100 FAX:763/489-3101 March 29, 2004 VIA MESSENGER Mr. Steve Rohlf Building and Zoning Administrator City of Elk River 13065 Orono Parkway Elk River, Minnesota 55330 RE: Conditional Use Permit Application Submittal, Schmidt Gravel Mine—Phase 4 Schmidt Gravel Mine, 11349 219th Street NW,Elk River, Minnesota(the Property) Dear Steve: Liesch Associates, Inc. (Liesch) is submitting this letter and accompanying Conditional Use Permit (CUP) Application submittal package (the Application) on behalf of Roger Schmidt and Schmidt Gravel Mining (Schmidt Gravel) for the above referenced Property. Figure 1 shows the location of the Property and Figure 2 shows the Existing Conditions, as of May 2003. The following documents are included with this letter and complete the Application: 1. Completed CUP Application signed by the applicant, including the application fee of $500.00 and consultant retainer fee of$500.00; 2. Plan Sheet A: Mining Area Grading Plan, Mining Area Restoration Plan, and Cross Sections, prepared by Liesch Associates, Inc., dated March 26, 2004; 3. Storm Water Pollution Prevention Plan, Schmidt Gravel Mine, Elk River, Minnesota, prepared by Liesch Associates, Inc., dated May 2003 and revised March 2004; 4. Completed Part 1: Basic Application, Minnesota Local/State/Federal Application Form for Water/Wetland Projects, signed by the applicant; and 5. Labels for property owners within 350 feet of the Property. Background Information In May 2003, the Property was rezoned for mineral extraction and a CUP was granted for operation of a gravel mine consisting of three phases. The following documents relating to the Property and existing CUP have been submitted to, reviewed, and approved by the City of Elk River: • Environmental Assessment Worksheet, Schmidt Gravel Mine, Elk River, Minnesota, prepared by Liesch Associates, Inc., dated January 2003. • Storm Water Pollution Prevention Plan, Schmidt Gravel Mine, Elk River, Minnesota, prepared by Liesch Associates, Inc., dated April 2003. • Environmental Spill Plan, Schmidt Gravel Mine, Elk River, Minnesota, prepared by Liesch Associates, Inc., dated April 2003. Page 2 Mr. Steve Rohlf March 29, 2004 • Jurisdictional Wetland Identification and Wetland Delineation for Proposed Schmidt Gravel Mine, Elk River, Minnesota, prepared by Liesch Associates, Inc., dated May 2003. • Memo to file from Leon Zeug, Liesch Associates, Inc., RE: Sediment Pond Design, Schmidt Gravel, dated May 15, 2003. • Plan Sheet 1 of 2 — Existing Conditions, Property Boundary, Watershed Boundaries and Wetlands Map, and Plan Sheet 2 of 2 —Development Phasing Plan and Details, Schmidt Gravel Mine, Elk River, Minnesota, prepared by Liesch Associates, Inc., dated May 2003. Description of Protect Schmidt Gravel is proposing to mine an additional area, Phase 4. located on the eastern portion of the Property, east of Phase 1 (see Plan Sheet A). Phase 4 consists of approximately 5.5 acres. Approximately 94,000 cubic yards of material will be removed. Mining of Phase 4 is proposed to be conducted from Phase 1 to up to the boundary of the adjacent wetland Area E to the east. Two soil borings (1A and. 2A) were completed in the area of Phase 4 on November 19, 2003. The locations of the borings are indicated on Figure 2. The boring logs indicate that soils in that area of Phase 4 consist of poorly graded sand with silt and gravel. Water levels were measured at the time of drilling however; it is not believed that they represent the actual water level. The boring logs are attached to this letter. Mining is proposed to be conducted to 15 feet below the water table or to an elevation of approximately 933 feet. It is anticipated that Phase 4 will ultimately produce 3.5 acres of Type 5 wetland (see Plan Sheet A). In the process, two small wetlands, Area F(0.10 acres) and Area G (0.09 acres), as shown on Figure 2, are located within the proposed Phase 4 and would be removed. These wetlands are unregulated due to their small size. The perimeter of the newly created wetland will be properly seeded upon completion. Due to the elevation of the water table in the area of the project (approximately 948-950 feet, based on information provided in the Environmental Assessment Worksheet prepared for the Property) it is not believed that mining of Phase 4 will significantly impact wetland Area E, as Area E is expected to be a ground water influenced wetland (elevation approximately 948 feet). Upon completion of mining activities, it is anticipated that a natural transition between the boundary of wetland Area E and the newly created Class 5 wetland of Phase 4 will occur. A "Part 1: Basic Application, Minnesota Local/State/Federal Application Form for Water/Wetland Projects" as required by the City, is included with the Application. Mining below the water table will be conducted using a drag line. No dewatering will be conducted at the site at any time. Drainage from Phase 4 will be directed to the open hole during mining (see Plan Sheet A). The Property is currently operating under a National Pollutant Discharge Elimination System (NPDES) Permit MNG490000 and a Storm Water Pollution Prevention Plan (SWPPP) and will continue to do so during Phase 4 mining. As indicated in the SWPPP, surface water runoff and erosion controls are proposed to control surface water discharge off site. The proposed controls will include installation of silt fence/hay bales, rip-rap placement in drainageways, and phased topsoil replacement and seeding of completed phases. Silt fence/hay bales and rip-rap will be placed in areas deemed necessary during mining operations. The SWPPP has been updated to include Phase 4 and is included with the Application. THE LIESCH COMPANIES MINNEAPOLIS. MN MADISON, WI SCOTTSDALE, AZ Page 3 Mr. Steve Rohlf March 29, 2004 The mined material will be hauled to Elk River Bituminous located approximately 1/4-mile south of the Property using a private access road, as approved as part of the original CUP. Mining operations be conducted between the hours of 7:00 AM and 7:00 PM as required by the City of Elk River. All mitigative measures currently in place at the Property as part of the previous CUP for Phases 1-3, (i.e dust control, noise control, and spill prevention and response), will be followed as part of Phase 4 mining.

MEMO TO: Steve Rohlf COMPANY: City of Elk River FROM: Matthew Ledvina, P.E. DATE: July 28, 2004 RE: Schuer, Inc./Schmidt Gravel Mine — Groundwater Monitoring Plan and Environmental Spill Plan Review NOTES/COMMENTS: As requested, I have reviewed the above referenced documents for the Schuer, Inc./Schmidt Gravel Mine. The following comments are provided in support of Conditional Use Permit (CUP) development for the Site. Groundwater Monitoring Plan Ground water elevations were measured in June and July 2004. An interpretation of the groundwater flow with a water table contour map should be provided from this data. The consistency of the groundwater level data should be assessed. The groundwater flow interpretation for the site should be assessed in relation to the regional hydrogeology. The monitoring schedule should identify that all three monitoring wells on the property be initially monitored for the listed parameters for two sampling events within a four week period to provide baseline of data for ongoing monitoring at the site. The annual groundwater sampling should include the sampling of, at a minimum, one of the upgradient wells in addition to MW-1. This will enable comparisons of water quality between upgradient and downgradient points at the site. Field parameters of pH, temperature and conductivity should be reported and interpreted with the analytic monitoring results for groundwater sampling. The City of Elk River should be notified ASAP if water quality monitoring data indicates the potential occurrence of environmental release. Water quality for groundwater sampling for the J&B monitoring should be incorporated into the assessment provided with the annual monitoring report. Environmental Spill Plan The Plan has been developed with an acceptable general outline. The existing SWPP should be reviewed and updated as necessary to reflect the Phase 4 mining • 0 0 0 0 MINNEAPOLIS HOUSTON DENVER PROVIDENCE ANCHORAGE 1000 IDS Center Suite 200 Tower One,Suite 580 Suite 2020 Key Bank Plaza,Suite 301 80 South Eighth Street 520 Post Oak Boulevard 1515 Arapahoe Street One Financial Plaza 601 W.Fifth Avenue Minneapolis, MN 55402 Houston,TX 77027 Denver,CO 80202 Providence, RI 02903 Anchorage,AK 99501 612.347.6789 432.203.1492 720.956.5300 401.278.4300 907.777.5300 Schuer, Inc./Schmidt Gravel Mine Page 2 activities. The Plan should state that there will be no maintenance of the equipment on the site. The Plan should identify to.contents and capacity of the spill kit that is provided with the refueling vehicle. A specific refueling location(s) should be identified in the Plan in an area(s)where spill response can be effectively implemented. The refueling location(s) would ideally be an area(s) with a relatively impermeable surface, closed contours and minimal slope.

T a, p / N > s g )%* of Memorandum akTO: Planning Commission River FROM: Rebecca Haug, Environmental Tech. 13065 Orono Parkway Elk River,MN 55330 DATE: August 24, 2004 SUBJECT: Wetland Conservation Act Decision — Schuer, Inc. -WCA 04-07 Proposal— Schuer, Inc. is proposing to impact 8,280 square feet of Type 2 wetland, all in one location, to accommodate the excavation of gravel. A map showing the proposed wetland impact and replacement is attached as part of the Planning Commission's memo on the Conditional Use Permit for this same request (see Development Plan). The Elk River City Council is the Local Unit of Government charged with decision- making authority for the Wetland Conservation Act (WCA). The wetland information has been provided to the Planning Commission so they have all relative information that may affect this project. Schuer, Inc. is proposing to expand a gravel mining operation adjacent to the J & B Mining site, which also has wetland impacts. The wetland restoration for the two projects ties together. Wetland restoration can't be deemed complete for either project until both are finished. Further, J & B Mining is purchasing some of the excess wetland credits from the Schuer site. FINDINGS Liesch Companies prepared a Wetland Delineation Report for the property. Combined notification of the proposed wetland impact and replacement plan was mailed out to the appropriate governmental agencies on June 2, 2004. The Technical Evaluation Panel (TEP) reviewed the delineation and replacement plan on May 5, 2004 and June 8, 2004. The minutes of these meetings are attached. The comment period on this issue ended on June 23, 2004. The appeal period for this issue is 15 working days after the Council's decision. RECOMMENDATION Staff recommends approval of the filling and mitigation plan for this project with the following stipulations: Phone: 763.635.1000 Fax:763.635.1090 www.ci.elk-riveunn.us 1. A restrictive covenant and drainage and utility easement be recorded over the mitigation and buffer areas. 2. The petitioner secures letter of credit in favor of the City of Elk River,which covers the cost of the mitigation work. 3. Monitoring of the wetland mitigation will commence as soon as restoration is completed on both this site and the Schuer, Inc. site and continue for a period of 3 to 5 years, as needed, as determined by city staff. The petitioner shall submit a written monitoring report on the replacement wetlands to the city after the first year of monitoring. Upon approval of this report by city staff the letter of wetland credit may be released. TEP Minutes — June 8, 2004 Attending: Brad Wozney, BWSR; Paul Diedrich, DNR-Fisheries; Yvonne Berner, ACOE; Terry Mauer, City Engineer; Roger Schmidt & Glen Johnson, Schmidt Gravel Mine; Jon Blaha and Warren Tuel, Liesch Assoc, Inc; Wayne Jacobson, Applied Environmental Services; Jason Bebeau & Michelle Christensen, J & B Mining; Donald Wester, Bill Saaranen, Duane Betker, Dean Mealhouse, Trout Brook Farms; Rebecca Haug and Steve Rohlf, City of Elk River Schuer Gravel Mine Leisch Assoc, Inc installed three monitoring wells and took soil borings. The information collected supports their earlier opinion that the wetlands at the site are supported by a shallow water table and not due to perched conditions. However, Bill Bronder is unsure if they have enough information to make that determination. It was discussed that the letter of credit guarantees that the wetland is supported by a shallow water table and not perched. If the plan doesn't work, the City will require them to fix it. Some of the additional wetland credits that this mine will have will be given to J & B Mining. Yvonne Berner explained that the ACOE may not accept these credits since they do not approve deep water habitats. It was discussed that there would be no dewatering at the site. The CUP for will need to be written in such a way to make sure the water levels are working. Monthly data for the monitoring wells will need to be provided to the City for the first year and quarterly data for the monitoring wells will need to be provided to the City for the second year. There may be a potential for bounce. Benchmarks will need to be established so a person can take elevations. GRO and DRO will need to be addressed. The wetland mitigation will be accomplished by removing the gravel deposits to a depth of 15 to 16 feet. Then fill will be brought back in up to grade in the Type 5 area, and 1 ft below the grade in the Type 3 area. Muck will be used to line the Type 3 area in preparation for planting. The second mitigation will be completed by removing the top 0.5 ft of existing reed canary grass and then replanting with natives. The slopes will be no greater than 5:1. A buffer area will be created averaging 25 ft in width. The Type 2 replacement is the only area that credit is wanted for. BWSR and ACOE are unsure they will be able to accept the credits because it is connected to deep water habitat. The TEP is satisfied with the wetland application for this project. J & B Mining Yvonne Berner emphasized to the applicant the importance of keeping their impacts under 2 acres. Also, the setbacks on the north, east and south sides for the mine will need to be changed. The setback adjoining the Schmidt mine may be already but the others will have to be 50 ft back. The setback changes will affect the wetland impacts so this will be looked at again at the next TEP meeting. There is still the issue of transportation for this project. Trott Brook Farms Homeowner's Association The Trott Brook Farms Homeowner's Association was in to discuss what can be done about the vegetation in and around their sedimentation ponds. It was discussed that barley straw can be added to the ponds in April to control the algae growth. It was also discussed that some of the cattails can be removed but the majority should remain because they absorb the nutrients that cause the algae bloom in the pond. It was also discussed that the association should talk to the lawn mowers about mowing the grass clippings away from the ponds. At this time, there are no rules restricting vegetation removal from sedimentation basis only recommendations. Bill Bronder gave them his card so they could further discuss options for vegetation. TEP Minutes — May 5, 2004 Attending: Paul Wozney, BWSR; Paul Diedrich, DNR-Fisheries; John Norgren, Sherburne County Ditch Inspector; Yvonne Berner & Marge Thompson, ACOE; Terry Mauer, City Engineer; Paul Cherne, Pioneer Engineering; Bill Blackwen, Pioneer Engineering; Roger Schmidt, Schmidt Gravel Mine; Jon Blaha and Warren Tuel, Liesch Assoc, Inc; Wayne Jacobson, Applied Environmental Services; Rebecca Haug and Steve Rohlf, City of Elk River Schuer Gravel Mine The applicant is proposing to mine gravel adjacent to an existing Type 2 wetland, which may or may not be a perched wetland. Liesch Assoc., Inc has been hired by the applicant to make this determination. They will be installing three monitoring wells. The applicant is proposing to restore the wetland and get credit for wetland banking. It was discussed as to whether or not the ACOE would approve a wetland bank for this type of project. Trout Brook Estates At the previous TEP meeting several changes were requested. The proposed trail at the end of Becker Trail has been relocated. Street has been shortened but the Park and Recreation Commission would like to see the trail to connect to Street E causing wetland impacts. Terry Mauer commented on the lack of accessibility to the sedimentation ponds by Outlot G. This will cause a change in Street E and the trail. Yvonne Berner stated that the ACOE is developing new criteria for trails. She also commented that if the project exceeds 10,000 sq. ft. (over 2 acres) of wetland impacts, the approval process will require a public notice and will be more difficult to receive approval. Lots 8 & 9, Block 20 were looked at since the City doesn't allow wetland fill for building sites. The road may be redesigned or the house made smaller to fit the sites. The same concerns were discussed for Lots 4 & 5, Block 15. A narrower house and retaining wall were discussed for Lot 9, Block 15. A new plan will be submitted; however, the TEP will not be discussing this project again. Robert Droen This homeowner is requesting a permit to dig out a wetland on his property and place the spoils on an upland area of his yard. ACOE does not regulate this activity. It was discussed that the slopes would be 4:1 and no deeper than 4 — 5'. (Bill Bronder and Rebecca Haug inspected the site on May 7, 2004. During the inspection it was determined that the wetland is a Type 2, 6 and he is exempt under WCA for his project.)
