Section 122-2-005 - Class V

Injection wells not included in Class I, II, III, or IV. Class V wells include, but are not limited to:

005.01 Air conditioning return flow wells used to return to the supply aquifer the water used for heating or cooling in a heat pump;

005.02 Cesspools or other devices that receive wastes, which have an open bottom and sometimes have perforated sides.;

005.03 Cooling water return flow wells used to inject water previously used for cooling;

005.04 Drainage wells used to drain surface fluid, primarily storm runoff, into a subsurface formation;

005.05 Dry wells used for the injection of wastes into a subsurface formation;

005.06 Recharge wells used to replenish the water in an aquifer;

005.07 Saltwater intrusion barrier wells used to inject water into a fresh water aquifer to prevent the intrusion of salt water into the fresh water;

005.08 Sand backfill wells used to inject a mixture of water and sand, mill tailings or other solids into mined out portions of subsurface mines;

005.09 Septic system wells used:

005.09A To inject sanitary waste from a dwelling, at a flow greater than 1,000 gallons per day; or

005.09B For an establishment, business, or community or regional system which generates sanitary waste and has the capacity to serve 20 persons or more; or

005.09C For dwellings, establishments, businesses, or community or regional systems that generate wastes other than sanitary wastes.

005.10 Subsidence control wells (not used for the purpose of oil or natural gas production) used to inject fluids into a non-oil or gas producing zone to reduce or eliminate subsidence associated with the overdraft of fresh water;

005.11 Injection wells associated with the recovery of geothermal energy for heating, aquaculture and production of electric power;

005.12 Wells used for solution mining of conventional mines such as stopes leaching;

005.13 Wells used to inject spent brine into the same formation from which it was withdrawn after extraction of halogens or their salts;

005.14 Injection wells used in experimental technologies;

005.15 Injection wells used for in-situ recovery of lignite, coal, tar sands, and oil shale; and

005.16 Motor vehicle waste disposal wells that receive or have received fluids from motor vehicle repair or maintenance activities.
