FPO - Adhesive Strip Please call and notify us if: • You wish to discuss necessary tree removal • You have a pet and/or locked gate, as we need a day's notice. • You do not own the property. NOTE: DO NOT attempt to prune or remove any tree that could come into close proximity with an energized conductor. It may be against the law and must be done by a qualified line clearance professional. The primary objective of the transmission line clearance program is to keep transmission facilities clear of all incompatible trees, brush and other vegetation that could grow too close to conductors. This is accomplished by routine maintenance on each transmission circuit, including tree removal, pruning, mowing and herbicide application. Each transmission right-of-way (ROW) has an established maintenance cycle depending on the work required. Maintenance objectives include: • Public and worker safety • Compliance with regulatory and legal requirements • Reliable electric service that allows for operational flexibility • Environmental stewardship and habitat enhancement Border Zone Wire Zone Variable Row Width 11/14P' Border Zone Wherever feasible, the wire zone/border zone concept (Bramble and Byrnes) shall be integrated into the vegetation management program to allow for different types and heights of vegetation in the ROW. The International Society of Arboriculture's booklet titled "Best Management Practices—Integrated Vegetation Management" provides a good working summary of this concept. This concept differentiates between the wire zone directly under the conductors and the remaining border zone. Generally, this concept allows for different, yet compatible, vegetation types in these separate zones. • Wire Zone: Area directly underneath the conductor(s). Vegetation in the wire zone consists of low -growing forbs and grasses. • Border Zone: Area that begins at the outside edge of the wire zone and extends to the edge of the easement. The border zone many contain additional low -growing woody plants and trees. • The wire zone/border zone concept, as applied by Xcel Energy, does not require removal of tall -growing trees if, at maximum mature height, the tree would not come within the distances set forth in the "Minimum Clearance Guidelines", even if the tree were to fall toward the conductors. Areas outside the border zone must be patrolled for hazard trees. Xcel Energy 103) Printed on recycled paper. xcelenergy.com I © 2015 Xcel Energy Inc.
