Class III Mineral Resources Injection/Pro

duction Well Operating Permits PURPOSE: This regulation controls the construction and opera tions of mineral resources injection/production wells. (1) Permits—General. (A) This rule applies to Class III injection/production wells used for the extraction of minerals including: 1. Sulfur mining by the Frasch process; 2. In-situ production of uranium or other metals. This cat egory includes only in-situ production from ore bodies which have not been conventionally mined; 3. In-situ combustion of fossil fuel; fossil fuels include coal, tar sands, oil shale, and any other fossil fuel which can be mined by this process; and 4. Solution mining of salts or potash. (B) This rule does not apply to wells used by generators of hazardous wastes or of radioactive wastes, by owners or oper ators of hazardous waste management facilities or by owners or operators of radioactive waste disposal sites to dispose of hazardous waste or radioactive waste into or above any under- ground formation. These types of wells are expressly forbidden under section 577.155, RSMo. (C) All persons who build, erect, alter, replace, operate, use, or maintain existing or proposed Class III injection/production wells shall apply to the department for applicable permits us ing application forms provided by the department. (D) Nothing in these regulations shall prevent the depart ment from taking action where the department finds that any activity that places, or permits to be placed, a water con taminant where it is reasonably certain to cause pollution of any waters of the state, or the activity otherwise violates Chapter 644, RSMo, the Missouri Clean Water Law, or these regulations. (E) Any information submitted to the department pursuant to these regulations may be claimed as confidential by the appli cant. Any claim must be asserted at the time of submission in the manner prescribed on the application form or instructions or, in the case of other submissions, by stamping the words confidential business information on each page containing the information. If no claim is made at the time of submission, the department may make the information available to the public without further notice. Claims of confidentiality for the follow ing information will be denied: 1. The name and address of any permit applicant or per mittee; and 2. Information which deals with the existence, absence or level of contaminants in drinking water. (F) The permittee shall give advance notice to the director of any planned changes in the permitted facility or activity which may result in noncompliance with permit requirements. (G) Applicants shall keep records of all data used to complete permit applications and any supplemental information submit ted under these regulations for a period extending from the date the application is signed to the date the permit expires for at least three (3) years. (2) Application. (A) An application for an operating permit shall be made for each injection/production well and shall include each of the following items. The application may be supplemented with copies of information submitted for other federal or state permits. 1. All items listed in 10 CFR 144.31(e); 2. Description of the process that will be used for the min eral extractions, including injection/withdrawal procedures; 3. Estimated depth of the well, casing lengths and weights, intervals to be cemented, and related well construction data as recommended by the office of the state geologist; 4. Maximum and average volume of injected fluids and injection pressure that will be used on a daily basis; 5. Appropriate application fee as listed in 10 CSR 20-6.011; 6. Recommendation and justification on the number and location of sampling wells by a registered professional engi neer or a qualified geologist as defined by sections 256.501 and 256.503, RSMo; 7. Where injection is into a formation which contains water with less than ten thousand milligrams per liter (10,000 mg/l) total dissolved solids (TDS), monitoring wells shall be: A. Completed into the injection zone and into any un derground sources of drinking water (USDW) above the injec tion zone which could be affected by the mining operation; B. Located in a fashion as to detect any excursions of in jection fluids, process by-products, or formation fluids outside the mining area or zone; and C. Located as not to be physically affected by a subsid ence or catastrophic collapse; 8. Where injection is into a formation which does not con tain water with less than ten thousand (10,000) mg/l TDS, no monitoring wells are necessary in the injection zone; 9. Where the injection wells penetrate an underground source of drinking water (USDW) in an area subject to subsid ence or catastrophic collapse, an adequate number of monitor ing wells shall be: A. Completed into the USDW to detect any movement of injected fluids, process by-products, or formation fluids into a USDW; and B. Located as not to be physically affected by a subsid ence or catastrophic collapse; 10. In determining the number, location, construction and frequency of sampling of the monitoring wells, the following criteria shall be considered: A. Population relying on the USDW affected or poten tially affected by the injection operation; B. Proximity of the injection operation to points of with drawal of drinking water; C. Local geology and hydrology; D. Operating pressures and whether a negative pressure is being maintained; E. Nature and volume of the injected fluid, the formation water, and the process by-products; and F. Injection well density; 11. Map(s) describing an area of review for each Class III injection/production well or group of wells, as determined by a registered professional engineer or a qualified geologist as defined by sections 256.501 and 256.503, RSMo. The area of review shall be that area the radius of which is determined by the lateral distance from a Class III injection/production well or perimeter of a group of wells in which the pressure in the in jection zone may cause the migration of injection or formation, or both, fluid into an USDW or into an improperly constructed, plugged, or abandoned well or test hole. A. The radius of the area of review may be calculated using a mathematical model (for example, modified Thesis equation) and shall be calculated for an injection time period at least equal to the expected life of the well(s). The owner or operator must demonstrate to the director that the mathemat ical model used and the calculated area of review are appro priate for the known hydrologic properties of the underlying formations. B. A fixed radius around the well or the perimeter of a group of wells of not less than one-half (1/2) mile may be used. In determining the fixed radius, the following factors shall be taken into consideration: chemistry of injected and formation fluids, hydrogeology, population and groundwater use and dependence, and historical practices in the area. C. If the area of review is determined by a mathematical model pursuant to subparagraph (2)(B)8.A. the permissible radius is the result of the calculation even if it is less than onehalf (1/2) mile. D. Nothing in this section shall prevent the director from imposing alternate areas of review when geologic or hydro logic conditions render a calculated or fixed area a potential threat to an underground source of drinking water; 12. Submit with the application a mapped and tabulated inventory of all known water supply, injection/production, abandoned and test wells, including field names or numbers and locations of the wells, public water systems, within the area of review and a separate tabulation of all the wells, which penetrate the injection zone listing each well’s type, con struction method, date drilled, location, depth, and record of plugging or completion, or both, including a description of all corrective action(s) proposed to be performed to render wells penetrating the injection zone sealed, plugged, or otherwise impervious to the migration of fluids into or between well bores, USDWs, or different aquifers. The applicant is responsi ble for the inventory and corrective action requirements of this section and shall extend every reasonable effort to locate all wells within the area of review of the applicant well(s); 13. A plan for plugging and abandonment. Where the plan meets the requirements of this paragraph, the director shall incorporate it into the permit as a condition. Where the di rector’s review of an application indicates that the permittee’s plan is inadequate, the director shall require the applicant to revise the plan, prescribe conditions meeting the requirements of this paragraph or deny the application. For purposes of this paragraph, temporary intermittent cessation of injection oper ations is not abandonment; 14.

Where the terms and conditions of the permit do not comply with applicable guidelines or requirements of the Clean Water Law and corresponding regulations or relevant federal laws. 2. Where the permit conditions do not ensure compliance with the applicable water quality requirements of any other affected states. 3. For the discharge of any pollutant not necessary to the extraction process, except thermal discharges; those produced pollutants contained in the formation water may be reinjected into a formation of the same TDS concentration. 4. For the discharge of any radiological, chemical, or bio logical warfare agent or radioactive waste. 5. For the construction or operation of a new injection/ production well which would degrade the usefulness of water withdrawn from earlier permitted wells. 6. For a well utilizing annular injection or production. (B) No well shall be operated so that fluid pressures in the in jection zone exceed the fracture pressure calculated or known for that formation. (C) New injection wells may not commence injection until construction is complete and— 1. The permittee has submitted notice of completion of construction to the director and— A. The director has inspected or otherwise reviewed the new injection well and finds it is in compliance with the con ditions of the permit; or B. The permittee has not received notice from the direc tor of the intent to inspect or otherwise review the new injec tion well within thirteen (13) days of the date of the notice in paragraph (5)(C)1. of this rule, in which case prior inspection or review is waived and the permittee may commence injection. (I) No operation shall commence until corrective ac tions outlined in paragraph (2)(A)12. and those required by the department have been completed. (6) Class III Injection/Production Well Construction Requirements. (A) All new injection/production wells shall meet each of the following conditions: 1. Wells are cased and cemented to prevent the migration of fluids into or between USDWs or potential sources of drink ing water; 2. The casing and cement used in construction of each newly drilled well is designed for the life of the well; 3. Consider the following factors when determining and specifying casing and cementing requirements: A. Depth to the injection/production zone; B.

Size and grade of all casing strings including wall thickness, diameter, nominal weight, length, joint specifica tion, and construction material; E. Corrosiveness of injection/production and formation fluids or combinations; F. Lithology of injection/production and confining zones; and G. Type and grade of cement. (B) Each well or group of wells utilizing a positive displace ment pump shall be equipped with both high and low safety switches which will shut down the pump in case of pressure increase over the authorized pressure or sudden pressure loss. (C) Appropriate logs and other tests shall be conducted during the drilling and construction of new injection/produc tion wells. A descriptive report shall be prepared by a qualified log analyst and submitted to the director. The logs and test ap propriate to each type of well shall be determined on the in tended function, depth, construction and other characteristics of the well, availability of similar data in the area of the drill ing site and the need for additional information that may arise from time-to-time as the construction of the well progresses. At a minimum, the logs and test shall include deviation checks conducted on all holes where pilot holes and reaming are used at sufficiently frequent intervals to assure that vertical avenues for fluid migration in the form of diverging holes are not creat ed during drilling. (7) Permits Transferable. (A) Subject to section (3), an opening permit may be trans ferred upon submission to the department of an application to transfer signed by a new owner. Until that time as the permit is officially transferred, the original permittee remains responsi ble for complying with the terms and conditions of the existing permit. (B) Within thirty (30) days of receipt of the application the de partment, shall notify the new applicant of the intent to revoke and reissue or transfer the permit. (8) Plugging and Abandonment. (A) Prior to abandoning Class III wells the well shall be plugged with cement in a manner which will not allow the movement of fluids between one (1) aquifer or formation and another. The director may allow Class III wells to use other plug ging materials if s/he is satisfied that the materials will prevent movement of fluids into or between USDWs. (B) Placement of the cement plugs shall be accomplished by one (1) of the following: 1. The balance method; 2. The dump method; 3. The two (2)-plug method; or 4. An alternative method approved by the director which will reliably provide a comparable level of protection. (C) The well to be abandoned shall be in a state of static equi librium with the mud weight equalized top to bottom, either by circulating the mud in the well at least once or by a compa rable method prescribed by the director prior to the placement of the cement plug(s). (D) The director shall prescribe aquifer cleanup and monitor ing where s/he deems it necessary and feasible to insure ade quate protection of USDWs. (E) The permittee shall notify the director at the times as the permit requires before conversion or abandonment of the well or in the case of area permits before closure of the project.
