Surface mining shall not include excavation or removal of shale, sand, gravel, clay, rock or other materials in remote areas by an owner or holder of a possessory interest in land for the primary purpose of construction or maintenance of access roads to or on such landowner's property. Surface mining shall not include excavations or grading conducted for forming, on-site road construction or other on-site construction, or the extraction of minerals other than anthracite and bituminous coal by a landowner for noncommercial use from land owned or leased by the landowner; nor mining for commercial purposes conducted under a Limited Use Permit issued by the Department; nor the extraction of sand, gravel, rock, stone, earth or fill from borrow pits for highway construction purposes, so long as such work is performed under a bond, contract and specifications which substantially provide for and require reclamation of the area affected; nor to the handling, processing or storage of slag on the premises of a manufacturer as a part of the manufacturing process. Surface mining shall not include the surface mining of coal or the surface effects of underground coal mining;

19. "Borrow pit" means the one-time or intermittent extraction of sand, gravel, rock, stone, earth or fill in its natural state, not being mechanically altered to affect its size for government-financed construction purposes. Such work shall be performed under a bond, contract and specifications which substantially provide for and require reclamation of the affected area; and
20. “Dimension stone quarry” means a site where natural stone used as building material is excavated and the stones are selected, trimmed, or cut to specified shapes or sizes.
