Enclosed for review please find the completed permit applications, supporting information, and a check for the $100 application fee from Barr Engineering Co. on behalf of Enbridge. Please send a copy of the permit authorization to me at Doug.Casina@enbridge.com and Adam Birr (Barr Engineering Co.) at ABirr@barr.com. Please send any hard copy authorization to: Barr Engineering Co. Attn: Adam Birr 325 South Lake Avenue, Suite 700 Duluth, MN 55802 If you have questions about the information presented in this permit application, please contact me at (218) 355-0808 or Adam Birr at (218) 788-6366. Sincerely, � ,� � Douglas Casina Environmental Advisor Enbridge Energy, Limited Partnership Enclosures: Land Use Permit (Shoreland) application Grading Permit application Supporting Information A check for$100 Cc: Adam Birr,Barr Engineering Co. � Supplemental I nformation Enbridge Energy, Limited Partnership Maintenance Work in Weirgor Township, Sawyer County, WI Line 6A, Milepost 81.9960 Project Description Enbridge Energy, Limited Partnership (Enbridge) plans to conduct maintenance activities on one segment of their existing Line 6A pipeline at Milepost 81.9960 in Township 37N, Range 7W, Section 30 of Sawyer County, Wisconsin (Figure 1). The project footprint is unavoidably located within 300 feet of an unnamed tributary to Swan Creek. Enbridge plans to conduct this work in the summer of 2022. Work at the site is expected to be completed within 7 to 14 days. Access to the site will be south from West County Road, then traveling southeast via an existing two-track road to the Enbridge right-of-way (ROV� and continuing southeast along the ROW to the site (Figure 2). The access route for the proposed maintenance work will cross an unnamed tributary via a temporary clear span bridge (TCSB; Figure 3). To construct the TCSB, construction mats will be set across the tributary. Construction mats will be used as ramps on the sides of the bridge. No fill will be used to construct the bridge. The bottom of the lowest beam of the clear span bridge will be at or above the top of the stream bank. The bridge and mats will be anchored to prevent them from being transported downstream during high flow conditions, as needed. Construction mats will be utilized to minimize wetland impacts along the access route and within temporary workspaces. The project scope will require excavation in order to inspect the pipeline and make any necessary repairs. The excavation will measure approximately 24 feet long by 20 feet wide and to a depth of 6 feet. The excavation will extend into an unnamed tributary to Swan Creek. The waterway measures approximately 6 feet wide by 4 feet deep, with a water level depth of approximately 0.5 feet taken on 6/16/21. If water is present, flow within the tributary will be temporarily diverted by a either a flume or dam and pump bypass method. Subsoil and topsoil will be segregated into separate piles. Temporary workspace and staging areas will be used for vehicle parking and equipment staging. Equipment used will include a hydrovac excavator, a backhoe (or similar excavator), and trucks to transport personnel and equipment. Best management practices (BMPs)will be installed prior to soil disturbance and in accordance with the Enbridge Environmental Protection Plan (EPP). Refer to attached site plan (Figure 3) and typical figures included in the application for additional details. BMPs will be maintained by Enbridge personnel, as necessary. Dewatering of the excavation may be required and will be conducted according to WPDES General Permit No. WI-0049344-05-0 for dewatering operations. Upon completion of the work, backfilling will begin immediately and the site will be restored to preconstruction conditions. Excavated subsoil will be backfilled first and then the topsoil to maintain the original soil horizons. Excavated areas in wetlands will be backfilled with topsoil originating from the wetlands. Backfill material from the waterway will consist of the spoil material excavated from the parent streambed. The bed and banks of the unnamed tributary to St. Louis River will be restored to as near as practicable to pre-construction conditions unless that slope is determined to be unstable. If Enbridge determines that the slope is unstable, the banks will be reshaped to prevent slumping. Once the banks are reshaped, BMPs will be installed immediately after backfilling. By restoring the original contours, existing flow patterns through the tributary will be maintained. Upon completing bank stabilization, the coffer dams will be removed to resume natural water flow. TCSB and construction mats will be removed. Temporary crossings and workspaces in wetlands will be allowed to revegetate from the native seed stock. A cover crop will be utilized in wetlands as necessary. All disturbed areas will be seeded and temporarily stabilized with straw mulch or erosion control blanket, depending on the site conditions. Refer to the attached restoration procedures for information regarding regrading, seeding and general restoration practices. Following completion of the work, it may be necessary to complete additional restoration work (e.g., additional grading, removal of BMPs, seeding, etc.). Temporary, non-biodegradable sediment control BMPs will be removed from the site after vegetation has been established. Enbridge will obtain landowner approvals for temporary staging and workspace areas located outside of Enbridge's ROW. All landowner approvals will be in place prior to beginning work. Restoration Procedures Routine Maintenance Work Enbridge Energy, Limited Partnership has an Environmental Protection Plan (EPP), which outlines environmental policies, procedures, and mitigation measures developed for pipeline maintenance projects. The EPP is intended to mesh with applicable federal, state and local environmental protection and erosion control specifications and practices. The EPP outlines general procedures for site restoration. Site restoration will begin as soon as soil conditions permit seed bed preparation and seed germination. Every effort will be made to begin site restoration, including installation of permanent erosion control measures, as soon as practicable. Final cleanup will begin with removal of all construction-related debris and material which is not an integral part of the pipeline (including litter generated by pipeline crews) from the Landowner's property. After clean up is completed, the disturbed areas shall be graded to restore the contours of the land to previous conditions. After final grading, slopes in areas other than cropland will be stabilized with permanent erosion control structures, as described below. Slopes Permanent berms (diversion dikes or slope breakers) will be installed on all slopes, according to the following maximum spacing requirements: Slope (%) Approximate Spacing (ft) 5 —15 300 >15 - 30 200 >30 100 Permanent berms will be constructed according to the following specifications: • Permanent berms will be installed with a 2 to 8 percent outslope. • Permanent berms will be constructed of compacted earth. • The outfall of berms will be directed toward appropriate energy-dissipating devices, and off the construction right-of-way if possible. • Permanent berms will be inspected and repaired as necessary to maintain function and prevent erosion. • Erosion control blanket (curlex, jute, or equivalent) will be placed on slopes over 30 percent. Revegetation Permanent revegetation will involve preparing the seedbed and seeding disturbed areas. The right-of-way will be seeded as soon as possible after backfilling, weather and soil conditions permitting. Specific seed mixes, application rates, and seeding dates will take into account recommendations of appropriate state and federal agencies and landowner requests as appropriate. Mulch will be applied according to the following specifications: • After seeding, slopes greater than 5 percent or dry, sandy areas will be mulched with 2 tons per acre of straw or hay or as otherwise directed by Enbridge. • All areas of dormant seeding must be mulched with 2 tons per acre of hay or straw or as otherwise directed by Enbridge. • Mulch will be anchored after placement to minimize loss by wind and water. If soil conditions allow, a mulch anchoring tool or farm disc set in the straight position will be used to crimp the mulch to a depth of 2 to 3 inches. Liquid tackifiers may be used with advance written approval from Enbridge. Where conditions allow (e.g., unsaturated and un-ponded areas), wetlands will be revegetated after final grading with annual ryegrass and then allowed to revegetate naturally, unless otherwise directed by regulatory agencies. Permanent revegetation at stream crossings will take into consideration recommendations of agencies as well as landowner requests. All soil conservation practices (such as terraces, grassed watenvays, etc.) that are damaged by the pipeline maintenance activities will be restored to previous conditions to the extent practical. .gad9 � r�-- � __ ' �.i . .. . �� �ke SuPen« ' efG�ee � . � .
