has determined drilling has ceased.(m) "Drilling operations" means all of the physical and mechanical aspects of constructing a well for the exploration or production of oil or gas, or both, for injection of fluids associated with the production of oil or gas, or both, or the storage of natural hydrocarbons or liquefied petroleum gas derived from oil or gas, and includes all of the following:(i) Moving drilling equipment onto the drill site.(ii) Penetration of the ground by the drill bit and drilling of the well bore.(iii) Casing and sealing of the well bore.(iv) Construction of well sites and access roads.(n) "Drilling unit" means the area prescribed by an applicable well spacing rule or order for the granting of a permit for the drilling and operation of an oil or gas well, or both.(o) "Facility piping" means piping that connects any of the following:(vii) Treatment equipment.(p) "Fence" means a structure that is designed to deter access and consists of not less than 2

structure that deters access.(q) "Final completion" means the time when locating, drilling, deepening, converting, operating, producing, reworking, plugging, and proper site restoration have been performed on a well in a manner approved by the supervisor, including the filing of the mandatory records, and when the conformance bond has been released.(r) "Flow line" means piping that connects a well or wells to a surface facility.(s) "Fresh water" means water that contains less than 1000 milligrams per liter of total dissolved solids.(t) "Gas storage" means the use of a depleted oil or gas pool, salt cavern, or other porous strata utilized for the purpose of injecting and withdrawing gas from the depleted oil or gas pool, salt cavern, or other porous strata.(u) "Gathering line" means a pipeline that transports natural gas from a surface facility to a transmission pipeline.(v) "Geologist" means a person who is certified as a geologist by a credible geological professional association or who, by reason of his or her knowledge of the natural sciences, mathematics, and the principles of geology acquired by professional education and practical experience, is qualified to engage in the practice of the science of geology.(w) "Groundwater" means water below the land surface in the zone of saturation.(x) "Injection well" means a well used to dispose of, into underground strata, waste fluids produced incidental to oil and gas operations or a well used to inject water, gas, air, brine, or other fluids for the purpose of increasing the ultimate recovery of hydrocarbons from a reservoir or for the storage of hydrocarbons.(y) "Instruction" means a written statement of general applicability, that is issued by the supervisor, conforms with the act and rules promulgated under the act, and clarifies or explains the applicability of the act or rules to commonly recurring facts or circumstances.(z)"Mineral water" means water that contains 1000 milligrams per liter or more of
