§ 3176.4 - Definitions.
As used in this subpart, the term:
Authorized officer means any employee of the Bureau of Land Management authorized to perform the duties described in 43 CFR parts 3000 and 3100 (43 CFR 3000.0-5).
Christmas tree means an assembly of valves and fittings used to control production and provide access to the producing tubing string. The assembly includes all equipment above the tubinghead top flange.
Dispersion technique means a mathematical representation of the physical and chemical transportation, dilution, and transformation of H
Escape rate means that the maximum volume (Q) used as the escape rate in determining the radius of exposure shall be that specified in paragraphs (1) through (4) of this definition, as applicable:
(1) For a production facility, the escape rate shall be calculated using the maximum daily rate of gas produced through that facility or the best estimate thereof;
(2) For gas wells, the escape rate shall be calculated by using the current daily absolute open-flow rate against atmospheric pressure;
(3) For oil wells, the escape rate shall be calculated by multiplying the producing gas/oil ratio by the maximum daily production rate or best estimate thereof; or
(4) For a well being drilled in a developed area, the escape rate may be determined by using the offset wells completed in the interval(s) in question.
Essential personnel means those on-site personnel directly associated with the operation being conducted and necessary to maintain control of the well.
Exploratory well means any well drilled beyond the known producing limits of a pool.
Gas well means a well for which the energy equivalent of the gas produced, including the entrained liquid hydrocarbons, exceeds the energy equivalent of the oil produced.
H
Lessee means a person or entity holding record title in a lease issued by the United States (43 CFR 3160.0-5).
Major violation means noncompliance which causes or threatens immediate. substantial, and adverse impacts on public health and safety, the environment, production accountability, or royalty income (43 CFR 3160.0-5).
Minor violation means noncompliance which does not rise to the level of a major violation (43 CFR 3160.0-5).
Oil well means a well for which the energy equivalent of the oil produced exceeds the energy equivalent of the gas produced, including the entrained liquid hydrocarbons.
Operating rights owner means a person or entity holding operating rights in a lease issued by the United States. A lessee may also be an operating rights owner if the operating rights in a lease or portion thereof have not been severed from record title (43 CFR 3160.0-5).
Operator means any person or entity including but not limited to the lessee or operating rights owner who has stated in writing to the authorized officer that he/she is responsible under the terms of the lease for the operations conducted on the leased lands or a portion thereof (43 CFR 3160.0-5).
Potentially hazardous volume means a volume of gas of such H
Production facilities means any wellhead, flowline, piping, treating, or separating equipment, water disposal pits, processing plant, or combination thereof prior to the approved measurement point for any lease, communitization agreement, or unit participating area.
Prompt correction means immediate correction of violations, with operation suspended if required at the discretion of the authorized officer.
Public Protection Plan means a written plan which provides for the safety of the potentially affected public with regard to H
Radius of exposure means the calculation resulting from using the following Pasquill-Gifford derived equation, or by such other method(s) as may be approved by the authorized officer:
(1) For determining the 100 ppm radius of exposure where the H
(2) For determining the 500 ppm radius of exposure where the H
(3) For determining the 100 ppm or the 500 ppm radius of exposure in gas streams containing H
(4) Where multiple H
(5) For a well being drilled in an area where insufficient data exits to calculate a radius of exposure, but where H
Zones known not to contain H
Zones known to contain H
Zones which can reasonably be expected to contain H
Zones which cannot reasonably be expected to contain H
