This is a geographical area which has been designated pursuant to [A.R.S. Title 45, Chapter 2, Article 2] as requiring active management of groundwater or, in the case of the Santa Cruz Active Management Area, active management of any water, other than stored water, withdrawn from a well. A.R.S. § 45-402(2)
Established Active Management Areas (AMAs) include: the Phoenix, Pinal, Prescott, Tucson and Santa Cruz AMAs.
Comprehensive environmental response, compensation, and liability act of 1980 (CERCLA) site
This is a location included in the federal government’s "Superfund" program, which investigates sites that are contaminated with hazardous substances. The Superfund program develops remedial actions that assure the protection of public health and welfare and the environment. The CERCLA program is administered by the United States Environmental Protection Agency (USEPA). The CERCLA Act of 1980 is authorized by P.L. 96-510; 94 Stat. 2767; 42 United States Code §§ 9601 through 9657.
Department of Defense (DOD) site
This is a location that is contaminated with hazardous substances. These locations typically are either active duty military bases or bases being closed under the Base Realignment and Closure (BRAC) regulations, as well as formerly used defense sites that are eligible for funding under the Installation Restoration Program as overseen by Arizona Department of Environmental Quality (ADEQ). DOD sites are administered by the US military and are authorized by the Defense Environmental Restoration Program, U.S.C. § 2701, et seq.
This is a type of well normally associated with a site investigation or remedial action. Environmental wells include air-sparging wells, biosparging wells, vapor extraction wells, free product recovery wells, vadose zone wells and wells involving other types of remediation. Environmental wells are permanent installations, as opposed to geotechnical or exploration boreholes that are drilled to obtain samples or information, and then are immediately abandoned.
This is a well having a pump with a maximum capacity of not more than thirty-five gallons per minute which is used to withdraw groundwater pursuant to A.R.S. § 45-454
. A.R.S. § 45-402(8)
Exempt wells are small non-irrigation wells, typically used to provide water for domestic purposes. Inactive management areas, withdrawals of groundwater from exempt wells for non-irrigation uses other than domestic purposes and stock watering shall not exceed 10 acre-feet per year. A.R.S. § 45-454(B)(2)
This is a well drilled in search of geophysical, mineralogical or geotechnical data. A.A.C. R12-15-801(13).
Groundwater withdrawal permit
This is a permit issued to withdraw groundwater in an AMA for a specific use that is authorized under A.R.S. Title 45, Chapter 2, Article 7. Authorized groundwater uses that require groundwater withdrawal permits include dewatering, temporary dewatering, emergency temporary dewatering, mineral extraction and metallurgical processing, general industrial use, poor quality groundwater, drainage water withdrawal, temporary electrical generation and hydrologic testing.
This is a well that is designed and drilled for the purpose of monitoring water quality within a specific depth interval. A.A.C. R12-15-801(1).
This is a well drilled within an Active Management Area that is drilled pursuant to a groundwater right authorized by A.R.S. Title 45, Chapter 2, Article 5, a service area right authorized by A.R.S. Title 45, Chapter 2, Article 6 or a groundwater withdrawal permit authorized by A.R.S. Title 45, Chapter 2, Article.
This is a well that is designed and drilled for the purpose of monitoring water levels within a specific depth interval. A.A.C. R12-15-801(20).
Special well construction or well abandonment requirements
These are well construction or well abandonment requirements or standards that exceed the minimum well construction requirements provided under A.A.C. R12-15-811 and A.A.C. R12-15-816. Special well construction or abandonment requirements are required: 1) where special aquifer conditions, such as those described in A.A.C. R12-15-812, exist; 2) when it is determined that the literal application of the minimum well construction standards would not adequately protect the aquifer or other water users (A.A.C. R12-15-821); and 3) in areas of known or anticipated groundwater contamination to prevent the risk of vertical cross-contamination (A.R.S. § 45-605(E)
and A.A.C. R12-15-850).
A specialty well is usually designed and constructed for a specific purpose other than to withdraw water, or to provide samples or monitoring data. Examples of specialty wells include cathodic protection wells, grounding wells, heat pump wells, etc.
Substantive Policy Statement
This is a written expression which informs the general public of an agency’s current approach to, or opinion of, the requirements of the federal or state constitution, federal or state statute, administrative rule or regulation, or final judgment of a court of competent jurisdiction, including, where appropriate, the agency’s current practice, procedure or method of action based on that approach or opinion. A substantive policy statement is advisory only. A substantive policy statement does not include internal procedural documents which only affect the internal procedures of the agency and does not impose additional requirements or penalties on regulated parties, confidential information or rules made in accordance with this chapter. A.R.S. § 41-1001(20)
Vadose zone well
A vadose zone well is constructed in the interval between the land surface and the top of the static water level. A.A.C. R12-15-801(26).
A variance is a request to construct or abandon a well in a manner that does not conform to one or more provisions of A.A.C. Title 12, Chapter 15, Article 8, (rules governing the well construction and the licensing of drillers) due to extraordinary or unusual conditions. Variances must be requested in writing, or by checking applicable responses on certain types of NOI forms.
Water Quality Assurance Revolving Fund (WQARF) site
This is a location included in the State of Arizona’s "Superfund" program, which investigates sites that are contaminated with hazardous substances. The Superfund program develops remedial actions that assure the protection of public health and welfare and the environment. The WQARF program is administered by ADEQ. It is authorized by A.R.S. § 49-282
Well driller report and well log
A well driller report must be filed by the well driller within 30 days of the completion of a well, and must describe the "as built" well construction information and also provide a well log of the well. The well driller report and well log are required by A.R.S. § 45-600
Well drilling contractor
This is an individual, public or private corporation, partnership, firm, association, or any other public or private organization or enterprise that holds a well driller’s license pursuant to A.R.S. § 45-595(B)
Well spacing and well impact rules
These are rules that govern the location of new wells and replacement wells in new locations in Active Management Areas to prevent unreasonably increasing damage to surrounding land or other water users from the concentration of wells. Well spacing and well impact rules are authorized pursuant to A.R.S. § 45-598(A)
and are set forth in A.A.C. R12-15 830.
