OAR 690-078-0080: Map to Accompany an Application for Water Use Permit for Chemical Process Mining

Maps submitted with applications for water use in chemical process mining shall be prepared by a certified water right examiner and meet the following criteria: (1) The application map, which is made part of the record, shall be of permanent quality and drawn with sufficient clarity so as to be easily reproduced. (2) Maps shall be drawn on tracing linen, tracing vellum or mylar except that maps measuring 11" x 17" or smaller may be prepared on good-quality paper. All maps shall be drawn to a standard, even scale of not less than 4 inches = one mile. Small area maps may be more easily and clearly drawn to a larger scale, such as one inch = 400 feet. (3) Four permanent-quality prints of other maps, such as deed description survey maps or county assessor maps, may also be used if all the required information is clearly shown on each print. A single print of these may be used only if it is reproduced as a transparency, such as a sepia print or on mylar film. (4) Each copy of the map shall show clearly each of the following requirements that apply to the proposed appropriation: (a) The location of each diversion point, well, or dam by reference to a recognized public land survey corner. The locations may be shown by distance and bearing or by coordinates (distance north or south and distance east or west from the corner); (b) The location of all canals, ditches, pipelines, or flumes; (c) The location of the place where water is to be used; (d) The scale to which the map is drawn, the section number, township, and range, and a north directional symbol.
