Current through Register Vol. 30, No. 28, July 12, 2024
A. The Director
				  may identify, by narrative description, illustration, maps, or other means, and
				  shall protect as USDWs, all aquifers and parts of aquifers that meet the
				  definition of USDW in R18-9-A601(70) except to the extent there is an
				  applicable aquifer exemption under subsection (B) of this Section or an
				  expansion to the areal extent of an existing Class II enhanced oil recovery or
				  enhanced gas recovery aquifer exemption for the exclusive purpose of Class VI
				  injection for geologic sequestration under subsection (D) of this Section.
				  Other than EPA-approved aquifer exemption expansions that meet the criteria set
				  forth in R18-9-A606(4), new aquifer exemptions shall not be issued for Class VI
				  injection wells. Even if an aquifer has not been specifically identified by the
				  Director, it is an USDW if it meets the definition in R18-9-A601(70).
B. Aquifer exemptions procedure:
1. The Director may identify, by narrative
				  description, illustrations, maps, or other means, and describe in geographic
				  and/or geometric terms, such as vertical and lateral limits and gradient, that
				  are clear and definite, all aquifers or parts thereof that the Director
				  proposes to designate as exempted aquifers using the criteria in
				  R18-9-A606.
2. No designation of an
				  exempted aquifer submitted as part of Arizona's UIC program shall be final
				  until approved by EPA as part of the Arizona UIC Program. No designation of an
				  expansion to the areal extent of a Class II enhanced oil recovery or enhanced
				  gas recovery aquifer exemption for the exclusive purpose of Class VI injection
				  for geologic sequestration shall be final until approved by the EPA as a
				  substantial revision of the Arizona UIC Program in accordance with
				  40 CFR
				  145.32.
3. Subsequent to the program approval or
				  promulgation, the Director may, after notice and opportunity for public
				  hearing, identify additional exempted aquifers.
4. Exemption of aquifers identified:
a. Under R18-9-A606(2) shall be treated as a
				  program revision under
				  40 CFR
				  145.32;
b. Under R18-9-A606(3) shall become final if
				  the Director submits the exemption in writing to the Administrator and the
				  Administrator has not disapproved the designation within 45 days.
Arizona Administrative Code › Title 18 - ENVIRONMENTAL QUALITY › Chapter 9 - DEPARTMENT OF ENVIRONMENTAL QUALITY - WATER POLLUTION CONTROL › Article 6 - UNDERGROUND INJECTION CONTROL › Part A - GENERAL PROVISIONS › Section R18-9-A606 - Criteria for Exempted Aquifers

Current through Register Vol. 30, No. 28, July 12, 2024
An aquifer or a portion thereof which meets the criteria
					 for an "USDW" in R18-9-A601(70) may be determined under R18-9-A605 to be an
					 "exempted aquifer" for Class I-V wells if it meets the criteria in subsections
					 (A)(1) through (A)(3) of this Section. Class VI wells must meet the criteria
					 under subsection (A)(4) of this Section.
1. It does not currently serve as a source of
				  drinking water; and
2. It cannot
				  now and will not in the future serve as a source of drinking water because:
a. It is mineral hydrocarbon or geothermal
				  energy producing, or can be demonstrated by a permit applicant as part of a
				  permit application for a Class II or Class III operation to contain minerals or
				  hydrocarbons that considering their quantity and location are expected to be
				  commercially producible;
b. It is
				  situated at a depth or location which makes recovery of water for drinking
				  water purposes economically or technically impractical;
c. It is so contaminated that it would be
				  economically or technologically impractical to render that water fit for human
				  consumption; or
d. It is located
				  over a Class III well mining area subject to subsidence or catastrophic
				  collapse; or

Current through Register Vol. 30, No. 28, July 12, 2024
Any underground injection, except into a well authorized
					 by rule or authorized by permit under the Arizona UIC program, is prohibited.
					 The construction of any well required to have a permit is prohibited until the
					 permit has been issued.
Arizona Administrative Code › Title 18 - ENVIRONMENTAL QUALITY › Chapter 9 - DEPARTMENT OF ENVIRONMENTAL QUALITY - WATER POLLUTION CONTROL › Article 6 - UNDERGROUND INJECTION CONTROL › Part B - GENERAL PROGRAM REQUIREMENTS › Section R18-9-B608 - Prohibition of Movement of Fluid into Underground Sources of Drinking Water

Current through Register Vol. 30, No. 28, July 12, 2024
A. No owner or
				  operator shall construct, operate, maintain, convert, plug, abandon, or conduct
				  any other injection activity in a manner that allows the movement of fluid
				  containing any contaminant into USDWs, if the presence of that contaminant may
				  cause a violation of any primary drinking water regulation under this Article,
				  as shown in Table 1, or may otherwise adversely affect the health of persons.
				  The applicant for a permit shall have the burden of showing that the
				  requirements of this subsection are met.
B. For Class I, II, III, and VI wells, if any
				  water quality monitoring of an USDW indicates the movement of any contaminant
				  into the USDW, except as authorized under this Article, the Director shall
				  prescribe such additional requirements for construction, corrective action,
				  operation, monitoring, or reporting (including closure of the injection well)
				  as are necessary to prevent such movement. In the case of wells authorized by
				  permit, these additional requirements shall be imposed by modifying the permit
				  in accordance with R18-9-C632 or the permit may be terminated under R18-9-C634
				  if cause exists, or appropriate enforcement action may be taken if the permit
				  has been violated. In the case of Class V wells authorized by rule see
				  R18-9-I650 through R18-9-I655 in Part I of this Article.
C. For Class V wells, if at any time the
				  Director learns that a Class V well may cause a violation of primary drinking
				  water regulations under this Article, they shall:
1. Require the injector to obtain an
				  individual permit;
2. Order the
				  injector to take such actions (including, where required, closure of the
				  injection well) as may be necessary to prevent the violation; or
3. Take enforcement action.

Current through Register Vol. 30, No. 28, July 12, 2024
A. When
				  injection does not occur into, through, or above an USDW, the Director may
				  authorize a well or project with less stringent requirements for area of
				  review, construction, mechanical integrity, operation, monitoring, and
				  reporting than required under this Article or R18-9-D636 to the extent that
				  reduction in requirements will not result in an increased risk of movement of
				  fluids into an USDW.
B. When
				  injection occurs through or above an USDW, but the radius of endangering
				  influence when computed under R18-9-B612(A) is smaller or equal to the radius
				  of the well, the Director may authorize a well or project with less stringent
				  requirements for operation, monitoring, and reporting than required under
				  R18-9-D636 to the extent that a reduction in requirements will not result in an
				  increased risk of movement of fluids into an USDW.
C. When reducing requirements under this
				  Section, the Director shall prepare a fact sheet under R18-9-C619 explaining
				  the reasons for the action.

1. The zone of endangering influence shall
				  be:
a. In the case of application or
				  applications for well permit or permits under R18-9-C616 that area the radius
				  of which is the lateral distance in which the pressures in the injection zone
				  may cause the migration of the injection and/or formation fluid into an USDW;
				  or
b. In the case of an application
				  for an area permit under R18-9-C624, the project area plus a circumscribing
				  area the width of which is the lateral distance from the perimeter of the
