Section 122-2-005 - Class V

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:

005.10 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005.13 Wells used to inject spent brine into the same formation from which it was withdrawn after extraction of halogens or their salts;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.

005.17 Class V wells are classified by the following groups, code numbers, and descriptions:
