§ 33.81. Specifications.

 (a)  The owner, operator, or superintendent of each mine shall make, or cause to be made, an accurate map or plan of the workings or excavations of the mine on a scale of not less than 200 feet to the inch.

 (b)  This map or plan shall exhibit the workings or excavations in each seam of limestone, clay, sandstone, ore or other material being worked and the tunnels and passages connecting with these workings or excavations. It shall state in degrees or in percentage of grade or elevation the general inclination of the strata in the workings or excavations along with any material deflection in such strata. It shall also state the approximate tidal elevations of the bottom of each shaft, slope, tunnel and entry, and of any other point in the mine or on the surface where such elevation shall be deemed necessary by the Department or its authorized representative. The map or plan shall show the number of the last survey station and the date of each survey on the entries or the most advanced workings. It shall also accurately show the boundary lines of the lands of the mine and the proximity of the workings to the mine.

 (c)  If the mine contains any water dammed up in any part of it the owner, operator or superintendent shall cause the true location of this dam to be accurately marked on the map or plan, together with the tidal elevation, inclination of strata and area of workings containing water. Whenever any workings or excavations approach the workings where the dam or water is contained or situated the owner, operator or superintendent shall notify the Department without delay.

 (d)  Maps or plans shall be plainly marked for ready identification with the name, number or other designation of the mine, the location of the mine, the name of the owner or operator, and the name of the superintendent. Maps or plans shall also indicate the principal material mined.

 (e)  A true copy of each map or plan so prepared shall be deposited with the Department. If so desired by the Department, the workings of each bed, seam, or vein shall be shown on separate sheets. One copy of the complete map or plan shall be kept at the mine. All maps and plans of mines which are deposited with the Department shall be the property of the Commonwealth. In no case shall any copy or inspection of any map or plan so deposited be made without the consent of the owner, operator or superintendent, except for use within the Department.
