Th following comments address our <br />concerns about maintai ing the safety, reliability and <br />integrity of this tran mission line. <br />1.

While this slope <br />late measures must be taken to <br />in the slope and protect it from <br />to weathering and run off. This <br />ortance in the vicinity of the <br />2. Such slope stabili ing measures would also be needed <br />along the West edg of the permit area to assure the <br />integrity of our 2 0,000 volt transmission line <br />structures locate just outside the area. <br />3. In order to maint <br />the line support <br />for maintenance t <br />must be restricte <br />of a 32 foot radi <br />the support poles <br />4.
