Arizona Administrative Code › Title 18 - ENVIRONMENTAL QUALITY › Chapter 9 - DEPARTMENT OF ENVIRONMENTAL QUALITY - WATER POLLUTION CONTROL › Article 6 - UNDERGROUND INJECTION CONTROL › Part G - CLASS III INJECTION WELL REQUIREMENTS › Section R18-9-G648 - Class III; 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 III 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 III well or area to operate or the construction of a new Class
				  III 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, public water systems 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
				  suspected. Only information of public record and pertinent information known to
				  the applicant is required to be included on this map.
3. A tabulation of data reasonably available
				  from public records or otherwise known to the applicant on wells within the
				  area of review included on the map required under subsection (B)(2) of this
				  Section which penetrate the proposed injection zone. 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.
4. Maps and cross sections indicating the
				  vertical limits of all USDWs within the area of review, their position relative
				  to the injection formation, and the direction of water movement, where known,
				  in every USDW which may be affected by the proposed injection;
5. Maps and cross sections detailing the
				  geologic structure of the local area;
6. Generalized map and cross sections
				  illustrating the regional geologic setting;
7. Proposed operating data:
a. Average and maximum daily rate and volume
				  of fluid to be injected;
b. Average
				  and maximum injection pressure; and
c. Qualitative analysis and ranges in
				  concentrations of all constituents of injected fluids. If the information is
				  confidential pursuant to R18-9-A603 an applicant may, in lieu of the ranges in
				  concentrations, choose to submit maximum concentrations which shall not be
				  exceeded. In such a case the applicant shall retain records of the undisclosed
				  concentrations and provide them upon request to the Director as part of any
				  enforcement investigation.
8. Proposed formation testing program to
				  obtain the information required by R18-9-G646(C).
9. Proposed stimulation program;
10. Proposed injection procedure;
11. Schematic or other appropriate drawings
				  of the surface and subsurface construction details of the well;
12. Plans (including maps) for meeting the
				  monitoring requirements of R18-9-G647(B);
13. Expected changes in pressure, native
				  fluid displacement, direction of movement of injection fluid;
14. Contingency plans to cope with all
				  shut-ins or well failures so as to prevent the migration of contaminating
				  fluids into USDWs;
15. 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)(5); and
16. The corrective action proposed to be
				  taken under R18-9-D639.
