Minnesota Department of Agriculture. Documentation verifying that the mulch has passed MCIA field inspection shall accompany the material upon delivery to the job site. At the time of delivery, all mulch shall be in air dried condition. Anchoring The contractor shall anchor Type 3 mulches with a disk, clod buster or other approved equipment. The mulch shall be anchored immediately after placement unless otherwise authorized by the engineer. Watering Spring and summer seedlings benefit from regular watering the 4-6 weeks. Watering should occur in the early morning, every other day, for half an hour. Reduce and Eliminate Impacts over Time The developer plans to use appropriate erosion control measures to prevent sedimentation and degradation of the remaining wetlands on site. Prior to construction or excavation, silt fence will be installed to intercept run-off. Immediately following grading of side slopes greater than 3:1, wood fiber blanket (or other slope stabilizing method approved by engineer) will be applied over approved seed mixture and a minimum 4" top -soil. Seed mix and mulch used on the project will be certified weed free. Erosion control installations will remain in place and be maintained in good condition by the contractor until the site has been re -vegetated. The contractor is to use best management practices with regards to erosion control — to include the following: • Inspect silt fences immediately after each half inch rainfall at least daily during prolonged rainfall. Immediately repair failed or failing silt fence. • Replacement — fabric shall be replaced promptly when it decomposes or becomes ineffective until the barrier is no longer necessary. • Sediment removal — sediment deposits shall be removed after each storm event when deposits reach approximately one-half the height of the barrier. Sediment remaining in place after the silt fence is no longer required shall be dressed to conform to the existing grade, prepared, and seeded with the appropriate seed mix. • Removal of silt fence — silt fences shall be removed when they have served their useful purpose, but not before the upward sloping area has been permanently stabilized. The owner is committed to conducting construction activities in compliance with all applicable federal, state and local requirements for water resource and wetland protection. Once the developer constructs the replacement wetlands, including vegetative cover, and the site grading is completed, there should be no adverse impacts to wetlands on the site or to any of the constructed wetlands. 4
