1. Consulting Utility Foresters Who we are and what we do June 2012 Heidi Knapp Transmission Consulting Utility Forester ISA Certified Arborist Arbormetrics Solutions, Inc. Asplundh Tree Expert Co.

2. 2 Identify annual maintenance work in the field, based on the utility’s requirements and line safety regulations. Notify the public in the areas in which we will be working. Gain permission and specialized instructions from the affected property owners or other jurisdictions for completion of the negotiated work. Provide tree crews with detailed work instructions to increase their efficiency and relay any special requests from the customers. Inspect the finished work on the corridors and maintain related documentation. Our basic functions as Utility Arborist Consultants

3. 3 Meeting PSE’s high standards of customer service: Our goal is to maintain good customer relations when negotiating vegetation work along the rights-of-way. This applies to all of our personnel, whether they be tree workers or support staff.

4. 4 Good communications are the essential key when associating with customers regarding our work.  A friendly and professional appearance and display of respect for property is the starting point in gaining consent for what we do.  A detailed enlightenment of the line safety and reliability factors is important.  Providing examples of the results of ineffective maintenance can portray the importance of our tasks. People, for the most part, choose to be compliant.  Electron Hydro Facility How we do what we do:

5. Drastic changes took place with the induction of the new NERC-generated standards on high-voltage lines. 5 Goldendale Hopkins Ridge

6. A Monumental Undertaking Prior to 2007  3-year maintenance cycle  Topped trees, including natives, were allowed in the wire zone  Border zone was not established  No enforced mature plant height restrictions After 2007  Annual maintenance cycle  Removal of tall-growing vegetation from the wire and border zones  Border zone restrictions were also considered and implemented, and corridors were widened  Mature height limitation of vegetation established at 15 ft. 6

7. Wire Zones and Border Zones Using the “wire zone/border zone method” for vegetation control means that only low-growing grasses and shrubs are allowed to grow in the area directly underneath the wires (wire zone). As you move away from the footprint of the wire towards the edge of the corridor (border zone), progressively larger types of vegetation are allowed. 7

8. Implementation of the new plan… “Honey, they’re gonna take down our treeee!”

9. Mrs. Miller’s Buckley Giant 9 Breaking the news face to face was occasionally very emotionally challenging for both parties.

10. 10 What were the negative reactions?  Occasional work denial  Angry, distraught, emotional customers What did we do?  Negotiated replacement vegetation or provided compensatory tree vouchers.  Referred them to PSE for further negotiation pursuant to the refusal process.

11. “Well then, what can I plant?” In order to educate customers about proper replacement vegetation, we provided plant lists, reference materials, and landscape design consultation suitable for the new specifications of the transmission line right-of-ways. 11

13. Controlling the Natives Vine Maple, Hazelnut, Elderberry, Cascara, Hawthorne, Serviceberry, Bitter Cherry, and many other medium-height natives must now be removed from the transmission right-of-ways to meet the new specifications. This requires annual treatment of these prolific species, including within our state and county forest lands and sensitive areas. 13
