NAC445A.849. Class V wells.

A Class V well is any injection well not included in Classes I, II, III and IV, including, without limitation:

     1. Wells used to inject the water for heating or cooling by a heat pump;

     2. Cesspools or other devices receiving wastes which have an open bottom and sometimes have perforated sides;

     3. Wells used to inject water previously used for cooling;

     4. Wells used to drain surface fluid, primarily the runoff from storms, into a subsurface formation;

     5. Wells used for the injection of fluids accumulated from dewatering operations;

     6. Drywells and wells used for the injection of nonhazardous wastes into a subsurface formation;

     7. Wells used to replenish the water in an aquifer;

     8. Wells used to inject water into an aquifer of fresh water to prevent the intrusion of water of a lower quality into the fresh water;

     9. Wells used to inject a mixture of water and sand, mill tailings or other solids into subsurface mines;

     10. Wells used to inject domestic sewage for facilities other than single-family residences and having a volume capacity of more than 3,000 gallons per day which are regulated as on-site sewage disposal systems pursuant to NAC 445A.950 to 445A.9706, inclusive;

     11. Wells used to inject fluids into a zone, other than an oil or gas producing zone, to reduce or eliminate subsidence associated with the overdraft of fresh water;

     12. Wells used for the storage of hydrocarbons in a gaseous state at standard temperature and pressure;

     13. Geothermal injection wells used in contact and noncontact heating and aquaculture, and in the production of energy;

     14. Wells used for solution mining of ores or minerals in conventional mines, such as stopes leaching;

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 Wells used to inject spent brine into the same formation from which it was withdrawn after extraction of halogens or their salts;

     16. Injection wells used in experimental technologies;

     17. Injection wells that are approved under a federal or state cleanup program and used to reinject pumped and treated contaminated groundwater, other than hazardous waste, back into the same formation;

     18. Injection wells used to inject fluids for the chemical or microbiological treatment of contaminated groundwater or soil; and

     19. Motor vehicle waste disposal wells.
