tLake Vegetation Management Plan Section VII: Variances and conditions of permits The commissioner may issue APM permits with a variance from one or more of the provisions of parts 6280.0250, subpart 4, and 6280.0350, except that no variance may be issued for part 6280.0250, subpart 4, items B and C. Variances may be issued to control invasive aquatic plants, protect or improve aquatic resources, provide riparian access, or enhance recreational use on public waters (6280.1000, subpart 1). Variance(s) and Justiiication(s) [check all that apply] ® Application of pesticides to control submerged vegetation in more than 15 percent of the littoral area (M.R. 6280.0350, Subp. 4, A). (list justification below) ❑ Application of pesticides to control aquatic macrophytes in natural environment lakes established pursuant to part 6120.3000 (M.R. 6280.0250, Subp. 4, E.). (list justification below) ❑ Mechanical control of aquatic macrophytes in more than 50 percent of the littoral area (M.R. 6280.0350, Subp. 3, B). (list justification below) n Waiver of dated signature requirement for invasive aquatic plant management permits because collecting a signatures would create an undue burden (M.S. 103G.615, Subp. 3a(b)). (list justification below) ❑ Other (please explain) Click here to enter text. Justifications (identify which variance and provide the rational for all items checked above): Narrative: A variance to the 15% limit is required to meet the goals LVMP mentioned above. Specifically the variance will allow bay -wide control of Eurasian Watermilfoil and Curly leaf pondweed; The 15% limit is a level of plant control the DNR has confidence in that will allow riparian owners access to the lake while maintaining the basic functions and benefits that aquatic plants provide. Most lakes never reach the 15% limit for chemical control of aquatic plants. A variance is required to remove more than 15% of the littoral area and monitoring of the plant community and the water quality is required to ensure that cumulative impacts of aquatic plant removal are not resulting in harm to the lake. One of the situations the DNR considers issuing a variance to the 15% limit is for the selective control of invasive species to enhance ecological and recreational benefits. Currently, Eurasian Watermilfoil makes up a significant proportion of the plant community and could be an ecological and recreational nuisance on Lake Owasso. A variance to the 15% limit is required to meet the goals LVMP mentioned above. Specifically the variance will allow bay -wide control of Eurasian Watermilfoil and Curly leaf pondweed; Lake Owasso LVMP 6
