The routine inspection and maintenance of the right of ways (ROW) are extremely important for the safety of the public and the personnel that are responsible for the operation/maintenance of the transmission lines. Maintaining right of ways in accordance with established procedures results in a high level of transmission line reliability.
2.0 Scope Includes the visual inspection of transmission line right of ways and the appropriate maintenance of those right of ways. Inspections (periodic aerial and as needed ground) are performed to monitor vegetation growth, right of way contractor maintenance effectiveness, and encroachments within the right of way. Maintenance activities may include any of the following: re-clearing vegetation (mowing, hand cutting, and herbicide application), tree trimming, danger tree cutting, and encroachment licensing/removal. This procedure shall be followed in accordance with the Transmission Maintenance Procedures Policy (MNT-TRMX-00000.
3.0 Equipment All 69kV through 500kV transmission line voltage classes and de-energized transmission lines used to maintain existing ROW easements.
4.0 Frequency Right of way maintenance frequency intervals are included in procedure MNT-TRMX-00051 (Transmission Line Equipment and Right of Way Maintenance Schedules).

S-AUTHORIZED COPY 5.0 Description of Work 5.1 Right of way re-clearing (using rotary mowers) -'All of the wooded sections of the right-of-way are to be recleared with rotary mowers, where possible, to the full width as noted in a detail description. All undergrowth is to be cut within six (6) inches of the ground. All vines on poles and brush around poles in fields are to be cut and removed out of cropped areas. Cut all leaning trees that have been pulled into the right-of-way by storms. All brush cut from stream banks or drainage ditches must be removed from streams and ditches so as not to impede the flow of water. When run ways are cut through existing canals, the canal must be restored to original condition allowing drainage to continue as it did before our operation. The vista screens and trimmed trees are not to be cut without specific instructions from Company representative.
5.2 Right of way reclearing (handcutting) -All of the wooded sections of the right-of way that cannot be recleared with rotary mowers are to be hand cut to the full width as noted in a detail description. All undergrowth is to be cut within six (6) inches of the ground or current water level. All vines on poles and brush around poles in fields are to be cut and removed out of cropped areas. Cut all leaning trees that have been pulled into the right-of-way by winter ice storms.
