Class I Injection Wells

Class I injection wells are used to inject fluids containing contaminants with concentrations greater than their maximum contaminant level (MCL) or other health-based standard. Class I wells are held to strict siting, construction, and operating standards to ensure that the emplaced fluids will not endanger underground sources of drinking water (USDWs).

Class I injection wells are classified as follows:

EPA Well Code Categories Description
1M
 Municipal Wells used to inject municipal waste fluids for disposal beneath the lowermost formation containing, within 2 miles of the well bore, an USDW.
1H
 Hazardous Industrial Wells used by generators of hazardous wastes or owners or operators of hazardous waste management facilities to inject hazardous waste for disposal beneath the lowermost formation containing, within 2 miles of the well bore, an USDW.
1I
 Non-Hazardous Industrial Wells used to inject non-hazardous industrial waste fluids for disposal beneath the lowermost formation containing, within 2 miles of the well bore, an USDW; this category includes disposal wells operated in conjunction with uranium mining activities.
1R
 Radioactive Waste Disposal Wells used to inject radioactive fluids beneath the lowermost formation containing, within 2 miles of the well bore, an USDW.
1X
 Other Wells used to inject fluids, other than those described above, for disposal beneath the lowermost formation containing, within 2 miles of the well bore, an USDW.

There are no Class I injection wells in Utah.
