060-11 Wyo. Code R. § 11-10
(a) Prior to quarrying or excavation of fossils from an Exclusive Commercial Fossil Removal Permit area, permittees shall have a land survey performed by a licensed Wyoming surveyor for the purpose of placing relatively permanent, locatable, corner stakes or markers that define the boundaries of the intended quarry or excavation. If warranted, the Office may also require a land survey for a quarry or excavation on a Non-Exclusive Fossil Removal Permit.
(b) Topsoil shall be stripped and segregated from permitted sites and stockpiled in such a manner as to minimize wind and water erosion. Topsoil stockpiles should be seeded within thirty (30) days of removal.
(c) Fossil removal sites shall be kept free of petroleum wastes, other toxic materials, and trash in general.
(d) To prevent unwarranted destruction of rare and unusual specimens, the use of heavy excavation equipment is prohibited on permitted fossil removal sites, except for the purposes of stripping top-soil and nonfossiliferous overburden, redistribution of waste rock, pit contouring during reclamation, the replacement of topsoil, and seeding of the disturbed area.
(e) Unless special permission is granted, all excavation sites shall be restored, as nearly as possible, to their original condition, to include backfilling of the site, replacement of topsoil, and reseeding.
(f) All camp sites used under Non-Exclusive Scientific Removal Permits during the course of any field investigations or excavations must be left clean, all refuse must be carried out, and adequate sanitation facilities must be maintained.
(g) State and County law enforcement agencies are authorized hereby to inspect all State land fossil quarry sites.
(h) Without prior written approval of the Board or the Office, no materials shall be pushed or dumped outside the surveyed boundaries of the quarry area, either during quarrying or during reclamation.
(i) The use of explosives on permitted fossil removal sites is prohibited.
