Section 90. Plats

A. When filing an application for a permit for a well or corehole, the applicant also shall file an accurate plat certified by a licensed professional engineer or licensed land surveyor on a scale, to be stated thereon, of 1 inch equals 400 feet (1:4800). The scope of the plat shall be large enough to show the board approved unit and all areas within the greater of 750 feet or one half of the distance specified in § 45.1-361.17 of the Code of Virginia from the proposed well or corehole. The plat shall be submitted on a form prescribed by the director.

B. The known courses and distances of all property lines and lines connecting the permanent points, landmarks or corners within the scope of the plat shall be shown thereon. All lines actually surveyed shall be shown as solid lines. Lines taken from deed or chain of title descriptions only shall be shown by broken lines. All property lines shown on a plat shall agree with any one of the following: surveys, deed descriptions, or acreages used in county records for tax assessment purposes.

C. A north and south line shall be given and shown on the plat, and point to the top of the plat.

D. Wells or coreholes shall be located on the plat as follows:

1. The proposed or actual surface elevation of the subject well or corehole shall be shown on the plat, within an accuracy of one vertical foot. The surface elevation shall be tied to either a government benchmark or other point of proven elevation by differential or aerial survey, by trigonometric leveling, or by global positioning system (GPS) survey. The location of the government benchmark or the point of proven elevation and the method used to determine the surface elevation of the subject well or corehole shall be noted and described on the plat.

2. The proposed or actual horizontal location of the subject well or corehole determined by survey shall be shown on the plat. The proposed or actual well or corehole location shall be shown in accordance with the Virginia Coordinate System of 1983, as defined in Chapter 17 (§ 55-287 et seq.) of Title 55 of the Code of Virginia, also known as the State Plane Coordinate System.

3. The courses and distances of the well or corehole location from two permanent points or landmarks on the tract shall be shown; such landmarks shall be set stones, iron pipes, T-rails or other manufactured monuments, including mine coordinate monuments, and operating or abandoned wells which are platted to the accuracy standards of this section and on file with the division. If temporary points are to be used to locate the actual well or corehole location as provided for in 4VAC25-150-290, the courses and distances of the well or corehole location from the two temporary points shall be shown.

4. Any other well, permitted or drilled, within the distance specified in § 45.1-361.17 of the Code of Virginia or the distance to the nearest well completed in the same pool, whichever is less, or within the boundaries of a drilling unit established by the board around the subject well shall be shown on the plat or located by notation. The type of each well shall be designated by the following symbols as described in the Federal Geographic Data Committee (FGDC) Digital Cartographic Standard for Geologic Map Symbolization:

Symbols for additional features as required in 4VAC25-150-510, 4VAC25-150-590, and 4VAC25-150-680 should be taken from the FDGC standard where applicable.

E. Plats shall also contain:

1. For a conventional gas and oil or injection well, the information required in 4VAC25-150-510;

2. For a coalbed methane gas well, the information required in 4VAC25-150-590; or

3. For a corehole, the information required in 4VAC25-150-680.

F. Any subsequent application for a new permit or permit modification shall include an accurate copy of the well plat, updated as necessary to reflect any changes on the site, newly discovered data or additional data required since the last plat was submitted. Any revised plat shall be certified as required in subsection A of this section.
