Injection Well

These pages last modified June 30, 2017


For the injection well classes listed below and regulated by DEQ, you may contact Hillary Young , Engineering Manager (405) 702-5100. For the injection wells regulated by the Oklahoma Corporation Commission (OCC), please contact the OCC Oil and Gas Division at (405) 521-2302 or on the web.

To increase ground water protection, a federal UIC program was established under the provisions of the Safe Drinking Water Act of 1974. Since then, state and federal regulatory agencies have modified existing programs or developed new strategies to protect ground water by establishing even more effective regulations to control permitting, construction, operation, monitoring and closure of injection wells.

The UIC Program in the Land Protection Division writes permits for, and performs inspections of, injection wells used for the disposal of liquids in underground geologic formations, except for those wells that, by state statute, are regulated by the OCC. Permits issued by LPD are for a 10-year period. If a facility submits a renewal application before the permit expiration date, the injection well may continue operations under the terms of the expired permit until the new permit is issued. Delegation of the federal program to the State of Oklahoma can be found in 40 CFR 147, Subpart LL. Federal regulations for the UIC program can be found in 40 CFR 144-148. DEQ’s UIC rules can be found in Oklahoma Administrative Code (OAC) 252:652.

The UIC program divides injection wells into five classifications. The classifications, and the agency with jurisdiction over them, are as follows:

CLASS I wells are used for injection of liquid hazardous and non-hazardous wastes beneath the lowermost underground sources of drinking water. DEQ has jurisdiction over these wells. Oklahoma currently has five Class I non-hazardous injection wells and no Class I hazardous waste injection wells.

CLASS II wells are used for injection of fluids associated with the production of oil and natural gas. The three types of Class II wells are enhanced recovery wells, disposal wells and hydrocarbon storage wells. OCC has jurisdiction over all Class II wells.

CLASS III wells inject fluids to dissolve and extract minerals such as uranium, salt, copper, and sulfur. Currently, there are no Class III injection wells in Oklahoma.

CLASS IV wells were used for injection of hazardous or radioactive wastes into or above an underground source of drinking water. In 1984, EPA banned the use of Class IV injection wells for disposal of hazardous or radioactive waste. Now, these wells may only be operated as a part of an EPA or state authorized clean-up action.

CLASS V wells are those not included in classes I – IV and are generally used for injection of non-hazardous fluids into or above an underground source of drinking water. DEQ has jurisdiction over the majority of these wells; however, OCC has jurisdiction over Class V wells used in the remediation of groundwater associated with underground or above ground storage tanks regulated by OCC.

Each UIC well with a permit issued by the Land Protection Division is identified below. Click the link for the facility of interest to view or download the permit. The permits displayed by these links are to ensure the public has greater access to the activities of the UIC Program but do not constitute official agency records. If you wish to review the official agency records, please contact DEQ’s Central Records office at (405) 702-1188 or email . While every effort has been made to ensure these web pages are up-to-date, if there is a discrepancy between the records presented on these pages and those in DEQ’s Central Records, the records from DEQ’s Central Records office will prevail.

Real Alloy Recycling, Inc.
Non-Hazardous Class I Injection Well

UIC Permit Number: IW-NH-3519019-R1
Address: P.O. Box 1070
Sapulpa, OK 74067
Facility Contact: Jim Bloomer
(918) 224-4746

Real Alloy Recycling, Inc. (Real Alloy) is located in Creek County near the city of Sapulpa. Real Alloy is involved in the production of secondary aluminum and, to a lesser extent, secondary magnesium metal and magnesium anodes for cathodic protection. Aluminum beverage cans and aluminum and magnesium scrap and dross are imported into the plant and recycled into aluminum remelt scrap ingots, secondary magnesium ingots, and magnesium cathodic protection anodes. This facility has been in continuous operation for almost 36 years on this site. The injection well is operated for the disposal of non-hazardous ammonia and chloride-contaminated storm water runoff, leachate and seepage from their closed non-hazardous industrial waste landfill and non-hazardous process waste water which is stored in a retention lagoon on-site.

American Zinc Recycling Corp.
Two Non-Hazardous Class I Injection Wells

UIC Permit Number: IW-NH-74006-R1
Address: P.O. Box 579
Bartlesville, OK 74005
Facility Contact: David Patton
  (918) 336-7100

American Zinc Reycling Corp., is located adjacent to the City of Bartlesville in Washington County, and is no longer in operation. At one time, the facility produced various metals from the smelting and refining of zinc concentrates, secondary materials, and other zinc-rich materials. Beginning in 1980, the facility maintained a waste management system, including two lined impoundments, a process water treatment facility, and two deep injection wells for storm water and process water control. Part of the facility has undergone closure and corrective action and is now in post-closure under RCRA Permit #OKD000829440. The active portion of the facility was a recycling facility that received metallic-rich by-products from the Horsehead facility in Palmerton, Pennsylvania and recovered lead-rich feedstocks for sale to the lead processing industry and zinc feedstocks which are sent to other Horsehead facilities for further refinement into commercial grade zinc products. Process wastewater was injected into the injection wells following treatment in the facility’s wastewater treatment plant. This process discontinued in 2012 and the facility is currently not injecting into the injection wells.

Mid-Way Environmental Services, Inc.
Non-Hazardous Class I Injection Well

UIC Permit Number:



120 N. 8th Ave.

The Mid-Way Environmental Services, Inc. (Mid-Way) commercial Class I non-hazardous waste injection well is located in Lincoln County, near Chandler. Mid-Way is also a permitted commercial solid waste processing facility that accepts shipments of non-hazardous industrial wastewater from various off-site sources. Those wastewaters are processed through the facility and disposed in the Class I injection well.


Oklahoma Gas & Electric Company
Non-Hazardous Class I Injection Well

UIC Permit Number: IW-NH-44001-OP
Address: 801 NE 34th Street
Newcastle, OK 79065
Facility Contact: Matt Schuerman
  (405) 387-6924

The injection well for Oklahoma Gas & Electric Company is located in McClain County approximately 2.5 miles southwest of the energy plant. The injection well system operates as needed to dispose of non-hazardous cooling tower reject water. This reject water is the water in the cooling tower system that has exceeded the maximum level of total dissolved solids and can no longer be recirculated through the cooling tower without impacting the cooling tower efficiency and air emissions. The injection well receives the wastewater by pipeline. The wastewater is filtered and stored at the energy plant prior to pumping to the injection facility.

Pryor Plant Chemical Company
Non-Hazardous Class I Injection Well

UIC Permit Number: IW-NH-49022-R1
Address: 16 South Pennsylvania Avenue
Oklahoma City, OK 73107
Facility Contact: John Carver

Located in Mayes County, this well was drilled and completed in 1968 by Oklahoma Ordnance Works Authority and acquired by the Pryor Plant Chemical Company in 2001. The Pryor Plant Chemical Company facility manufactures nitrogen fertilizers. In addition to fertilizer, the plant produces ammonia and nitrate as part of the manufacturing process. The injection well is used for the disposal of process wastewater and storm water runoff.
