  3. What does field inspection look for? • Accuracy of maps • Areas with land use or features affecting the route • Locations that raise code compliance or clearance questions (grain bins, buildings, lakes) • Examine objector property/issues • Nature of eminent domain parcels

  4. Field Inspections 11.3(7)Compliance with Iowa electrical safety code. If review of Exhibit C, or inspection of an existing electric line which is the subject of a franchise petition, finds noncompliance with 199 IAC 25, the Iowa electrical safety code, no final action will be taken by the board on the petition without a satisfactory showing by petitioner that the areas of noncompliance have been or will be corrected.

  5. Iowa Electrical Safety Code The Iowa Electrical Safety Code is defined in Chapter 25 of the Board’s rules.

  6. NESC Edition 25.2(1) currently adopts the 2007 edition of the NESC with a few modifications.

  7. Clearances Over Water 25.2(2)b(2) The following clearances shall apply to all lines regardless of date of construction: NESC 232, vertical clearances for “Water areas not suitable for sailboating or where sailboating is prohibited,” “Water areas suitable for sailboating. . .,” and “Established boat ramps and associated rigging areas. . .”; and NESC 234E, “Clearance of Wires, Conductors, Cables or Unguarded Rigid Live Parts Installed Over or Near Swimming Areas With No Wind Displacement.”

  8. Water Crossing Permits 25.2(2)b(2) Table 232-1, Footnote 21, is changed to read: “Where the U.S. Army Corps of Engineers or the state, or a surrogate thereof, issues a crossing permit, the clearances of that permit shall govern if equal to or greater than those required herein. Where the permit clearances are less than those required herein and water surface use restrictions on vessel heights are enforced, the permit clearances may be used.”

  9. Guy Markers 25.2(2)d Rule 217C.1 is changed to read: “The ground end of anchor guys exposed to pedestrian or vehicle traffic shall be provided with a substantial marker not less than eight feet long. The guy marker shall be of a conspicuous color such as yellow, orange, or red.

Noncomplying guy markers shall be replaced as part of the utility’s inspection and maintenance plan.”
