Iowa Admin. Code r. 199-14.8
Any map, plan and profile drawing, or oversized document that is to be filed with the commission should be electronically filed as a PDF (Portable Document Format) or such electronic format as designated by the commission. If the map, drawing, or oversized document cannot be printed on 11- by 17-inch or smaller-sized paper in legible and usable form, as determined by the commission, the original and four paper copies of each map, drawing, or other document filed pursuant to this rule should also be filed unless more copies are directed by commission order or request. Maps and other documents should be drawn to a scale appropriate for the level of detail to be shown. However, if the map, drawing, or other document is not electronically filed, then the number of paper copies filed is governed by other applicable rules, including the "hearings" rule in 199-Chapter 7, which concerns the required number of copies for evidence introduced at hearing, and 199-Chapter 26, which contains additional requirements regarding the number of paper copies of minimum filing requirements required to be filed in rate and tariff proceedings.
