Maps (Chapter 140)






I.  Summary


  We adopt the following Technical Specifications to implement the Commission’s requirements for Utility Service Area and Infrastructure Maps contained in Chapter 140 of the Commission’s Rules.



II.  Background


  On October 19, 2001, the Commission adopted Chapter 140 of its Rules, Utility Service Area and Infrastructure Maps.  That Rule became effective on October 29, 2001.  Section 1(E) of Chapter 140 “delegates to the Director of the Technical Analysis Division the responsibility to establish additional technical specifications for maps filed with the Commission” pursuant to the Rule. 


  That provision requires that the Director “consult with the Maine Office of GIS, the Maine Department of Transportation, and the Maine Drinking Water Program” before establishing such specifications.  On November 1, 2001, the Director forwarded a draft of this document to those agencies for comment, and we have reflected their comments in the Technical Specifications below.

  Pursuant to Section 1(E) of Chapter 140, in addition to requirements stated in that Rule, utilities filing maps required by Chapter 140 shall comply with the following technical specifications:


  A.  Paper Copy Maps


  1.  Maps must include at least four points of known geographic location (e.g., latitude and longitude) evenly distributed across the map.


  B.  Electronic Copy Maps


  1.  If paper copy maps are used as a source for digitizing, they must be prepared using a 1:24,000 scale base and conform to National Map Accuracy Standards (NMAS).  If data are collected by other means (e.g., GPS, imagery), techniques must be sufficient to ensure compliance with NMAS for 1:24,000 scale data.


  2.  Electronic copy maps should conform to applicable provisions of the most recently approved edition of the Maine Office of GIS (MeGIS) Data Standards published on the MeGIS web site at


  3.  Electronic copy maps must be provided on a 3˝” diskette, a 100 Mb or 250 Mb Zip disk, or a CD.



IV.  Notice;  Effective Date
