(b) "ANSI" means the American national standards institute.

(c) "API" means the American petroleum institute.

(d) "Area of review" means either of the following:

(i) For a well disposing of nonhazardous waste that area the radius of which is the greater of 1/4 mile or the lateral distance in which the pressures in the injection zone are sufficient to increase hydrostatic head in the injection zone above the base of the lowermost underground source of drinking water, but shall not be more than 2 miles.

(ii) For a well disposing of hazardous waste that area the radius of which is the greater of 2 miles or the lateral distance in which the pressures in the injection zone are sufficient to increase hydrostatic head in the injection zone above the base of the lowermost underground source of drinking water.

(e) "Area of injectate migration" means that area the radius of which is the calculated lateral distance over which injectate will migrate over the proposed life of a disposal well.

(f) "Authorized representative of the supervisor of mineral wells" means a department of environmental quality employee who is charged with the responsibility for implementation of the act or rules.

(g) "Blowout prevention equipment" means a casinghead control device designed to control the flow of fluids from the well bore by closing around the drill pipe or production tubing or completely sealing the hole in the absence of drill pipe or production tubing.

(h) "Briefing area" means a specified geographic area, where all personnel may safely assemble in an emergency.

(i) "Change of well status" means any of the following:

(i) To make changes or alterations in the permanent nonretrievable well equipment.

(ii) To make changes or alterations in the original relationship between the permanent nonretrievable well equipment and the adjacent geologic formations.

(iii) Fracture stimulation of a well.

(iv) Deepening of a well.

(v) Temporarily abandoning a well. Change of well status does not include well stimulation required during normal operation.

(j) "Colorimetric or length of stain tubes" means glass tubes that contain a chemical which changes color upon exposure to a specified substance and which allow the concentration of the specified substance to be read directly.

(k) "Conformance bond" means a surety bond that has been executed by a surety company authorized to do business in this state, cash, certificates of deposit, letters of credit, or other securities that are filed by a person and accepted by the supervisor of mineral wells to ensure compliance with the act, these rules, permit conditions, instructions, orders of the supervisor of mineral wells, or an order of the department.

(l) "Directionally drilled well" means a well purposely deviated from the vertical using controlled angles to reach an objective subsurface location.

(m) "Drilling completion" means the time when a well has reached its permitted depth or the supervisor of mineral wells has determined drilling has ceased.

(n) "Emergency preparedness coordinator" means an individual appointed under 1976 PA 390, MCL 30.401 et seq. to coordinate emergency planning or services within the county or municipality.

(o) "External mechanical integrity" means a well subject to this part has no significant fluid movement through vertical channels adjacent to the well bore.

(p) "Facility piping" means piping that connects any of the following:

(i) Compressors.

(ii) Flares.

(iii) Loadouts.

(iv) Separators.

(v) Storage tanks.

(vi) Transfer pumps.

(vii) Treatment equipment.

(viii) Vents.

(q) "Fence" means a structure that is designed to deter access and which consists of not less than 2 strands of barbed wire, 1 strand being approximately 18 inches above the ground and the other strand being approximately 42 inches above the ground, secured to supporting posts or means an equivalent structure that deters access.

(r) "Final completion" means either of the following:

(i) 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 of mineral wells, including the filing of the mandatory records.

(ii) The time when a permit has been issued to convert an existing well subject to this part to a purpose allowed under another act or another part of the act.

(s) "Flare" means a device for the burning of gasses in which the flame is exposed to the atmosphere and burning takes place at a height of not less than 20 feet above the ground.

(t) "Flow line" means piping that connects a well or wells to a surface facility.

(u) "Fresh water" means water which is free of contamination in concentrations that may cause disease or harmful physiological effects and which is safe for human consumption.

(v) "Fresh water drilling fluid" means any fluid used for drilling a well which contains fewer than 11,000 milligrams per liter total dissolved solids. Fresh water drilling fluid does not include an oil-based drilling fluid.
