Horizontal well means a well bore drilled laterally at an angle of at least eighty (80) degrees to the vertical or with a horizontal projection exceeding one hundred (100) feet measured from the initial point of penetration into the productive formation through the terminus of the lateral in the same common source of supply.
Built-Up Area and/or “Covered Area” in relation to a Flat shall mean the floor area of that Flat including the area of balconies and terraces, if any attached thereto, and also the thickness of the walls (external or internal) and the columns and pillars therein Provided That if any wall, column or pillar be common between two Flats, then one-half of the area under such wall column or pillar shall be included in the built-up area of each such Flat.
Deep well means a well located and constructed in such a manner that there is a continuous layer of low permeability soil or rock at least 5 feet thick located at least 25 feet below the normal ground surface and above the aquifer from which water is to be drawn.
stratigraphic test well means a drilling effort, geologically directed, to obtain information pertaining to a specific geologic condition. Ordinarily, such wells are drilled without the intention of being completed for hydrocarbon production. They include wells for the purpose of core tests and all types of expendable holes related to hydrocarbon exploration. Stratigraphic test wells are classified as (i) "exploratory type" if not drilled into a proved property; or (ii) "development type", if drilled into a proved property. Development type stratigraphic wells are also referred to as "evaluation wells".
Water Surface Elevation (WSE means the height, in relation to NAVD 1988, of floods of various magnitudes and frequencies in the floodplains of riverine areas.
Lot depth Means the horizontal distance between the front and rear lot lines. If the front and rear lot lines are not parallel, “lot depth” means the length of a straight line joining the middle of the front lot line with the middle of the rear lot line. If there is no rear lot line, “lot depth” means the length of a straight line joining the middle of the front lot line with the apex of the triangle formed by the side lot lines. (See illustration page at end of Section.)
Water well means an excavation that is drilled, cored, bored, augered, washed, driven, dug, jetted, or otherwise constructed for the purpose of exploring for groundwater, monitoring groundwater, utilizing the geothermal properties of the ground, or extracting water from or injecting water into the aquifer. “Water well” does not include an open ditch or drain tiles or an excavation made for obtaining or prospecting for oil, natural gas, minerals, or products mined or quarried.
ILUA Area means the geographical area in relation to which the Framework ILUA applies, as specified in Schedule 2 of the Framework ILUA;
Shallow well means a well located and constructed in such a manner that there is not a continuous layer of low-permeability soil or rock (or equivalent retarding mechanism acceptable to the department) at least 5 feet thick, the top of which is located at least 25 feet below the normal ground surface and above the aquifer from which water is to be drawn.
Area of shallow flooding means a designated AO or AH Zone on a community's Flood Insurance Rate Map (FIRM) with one percent or greater annual chance of flooding to an average depth of one to three feet where a clearly defined channel does not exist, where the path of flooding is unpredictable and indeterminate; and where velocity flow may be evident. Such flooding is characterized by ponding or sheet flow.
Water surface elevation means the height, in relation to the National Geodetic Vertical Datum (NGVD) of 1929, the North American Vertical Datum (NAVD) of 1988, or other datum, where specified, of floods of various magnitudes and frequencies in the floodplains of riverine areas.
Basal area means the effective surface area available to transmit the treated effluent from the filter media in a mound system into the in-situ receiving soils. The perimeter is measured at the interface of the imported fill material and in-situ soil. On sloping sites, only the area down-gradient from the up-slope edge of the distribution media may be included in this calculation.
borehole means a hole sunk into the earth for the purpose of locating, abstracting or using subterranean water and includes a spring;
Gas well means a well producing gas or natural gas from a common source of gas supply as determined by the commission.
Drilling unit means the area fixed for the drilling of one well by order or rule of any state or federal body having authority. If a Drilling Unit is not fixed by any such rule or order, a Drilling Unit shall be the drilling unit as established by the pattern of drilling in the Contract Area unless fixed by express agreement of the Drilling Parties.
Area B means the area marked “Area B” outlined in orange on the Plan;
PAD means a Preauthorized Debit.
Test Well means a well constructed for the purpose of obtaining information needed to design a well prior to its construction. Test wells are cased and can be converted to observation or monitoring wells and under certain circumstances to production wells
Underground tank means a device meeting the definition of tank whose entire surface area is totally below the surface of and covered by the ground.
Acre-foot means the amount of water necessary to cover one acre of land to the depth of one foot, or 325,851 U.S. gallons of water.
Oil well means any well capable of producing oil or oil and casinghead gas from a common source of supply as determined by the commission.
Underground area means an underground room, such as a basement, cellar, shaft or vault, providing enough space for physical inspection of the exterior of the tank situated on or above the surface of the floor.
Casing means a pipe or tubing of appropriate material, of varying diameter and weight, lowered into a borehole during or after drilling in order to support the sides of the hole and thus prevent the walls from caving, to prevent loss of drilling mud into porous ground, or to prevent water, gas, or other fluid from entering or leaving the hole.
Diameter at Breast Height (DBH) means the diameter of a tree at 4 1/2 feet above the ground measured from the uphill side.
Diameter means the diameter of the stem of a tree measured outside the bark at a specified point of measurement.
Surface waters means all waters of the state as defined in G.S. 143-212 except underground waters
