Arizona Administrative Code › Title 18 - ENVIRONMENTAL QUALITY › Chapter 9 - DEPARTMENT OF ENVIRONMENTAL QUALITY - WATER POLLUTION CONTROL › Article 6 - UNDERGROUND INJECTION CONTROL › Part F - CLASS II INJECTION WELL REQUIREMENTS › Section R18-9-F645 - Class II; Information to be Considered by the Director

Current through Register Vol. 30, No. 28, July 12, 2024
A. This Section
				  sets forth the information which must be considered by the Director in
				  authorizing Class II wells. Certain maps, cross sections, tabulations of wells
				  within the area of review, and other data may be included in the application by
				  reference provided they are current, readily available to the Director and
				  sufficiently identified to be retrieved.
B. Prior to the issuance of a permit for an
				  existing Class II well to operate or the construction or conversion of a new
				  Class II well the Director shall consider the following:
1. Information required in
				  R18-9-C616.
2. A map showing the
				  injection well or project area for which a permit is sought and the applicable
				  area of review. Within the area of review, the map must show the number or name
				  and location of all existing producing wells, injection wells, abandoned wells,
				  dry holes, and water wells. The map may also show surface bodies of waters,
				  mines (surface and subsurface), quarries and other pertinent surface features
				  including residences and roads, and faults if known or suspended. Only
				  information of public record and pertinent information known to the applicant
				  is required to be included on this map. This requirement does not apply to
				  existing Class II wells.
3. A
				  tabulation of data reasonably available from public records or otherwise known
				  to the applicant on all wells within the area of review included on the map
				  required under subsection (B)(2) of this Section which penetrate the proposed
				  injection zone or, in the case of Class II wells operating over the fracture
				  pressure of the injection formation, all known wells within the area of review
				  which penetrate formations affected by the increase in pressure. Such data
				  shall include a description of each well's type, construction, date drilled,
				  location, depth, record of plugging and completion, and any additional
				  information the Director may require. In cases where the information would be
				  repetitive and the wells are of similar age, type, and construction the
				  Director may elect to only require data on a representative number of wells.
				  This requirement does not apply to existing Class II wells.
4. Proposed operating data:
a. Average and maximum daily rate and volume
				  of fluids to be injected;
b.
				  Average and maximum injection pressure; and
c. Source and an appropriate analysis of the
				  chemical and physical characteristics of the injection fluid.
5. Appropriate geological data on
				  the injection zone and confining zone including lithologic description,
				  geological name, thickness and depth.
6. Geologic name and depth to bottom of all
				  USDWs which may be affected by the injection.
7. Schematic or other appropriate drawings of
				  the surface and subsurface construction details of the well.
8. In the case of new injection wells the
				  corrective action proposed to be taken by the applicant under
				  R18-9-D639.
9. A certificate that
				  the applicant has assured through a performance bond or other appropriate
				  means, the resources necessary to close, plug or abandon the well as required
				  by R18-9-D636(A)(6).
