PGE has prescribed standards for the clearance of vegetation located under, near and around our overhead and underground infrastructure near our poles on a site-specific and construction-specific basis. Additionally, PGE subscribes to the principles of Integrated Vegetation Management (IVM) in the right of way. This promotes the retention of desirable vegetation species as a means of biological control, which helps in response to climate change and fuel loading. Other IVM methods may include a combination of chemical, cultural, mechanical, and/or manual treatments. PGE’s FITNES program identifies vegetation within proximity to certain types of assets (expulsion fuse, etc.) and prescribes treatment to the site as needed to maintain necessary clearances.
