Rule 74:55:01:29 Well mechanical integrity test.

          74:55:01:29.  Well mechanical integrity test. Prior to putting a new well into service or reissuance of a permit for a salt solution well, the well shall be tested by the owner or operator to determine the mechanical integrity of the well. A well is considered to be of acceptable mechanical integrity if no leak exists in the casing, tubing, or packer and no fluid movement takes place into an underground source of drinking water through annulus channels adjacent to the injection well bore. A schedule and methods for mechanical integrity testing shall be included in the permit, and constitute conditions of the permit. The schedule and methods shall meet the following requirements:

 

          (1)  One of the following methods must be used to evaluate the absence of significant leaks in the casing, tubing or packer:

 

               (a)  Following an initial pressure test, monitoring of the tubing-casing annulus pressure with sufficient frequency to be representative, as determined by the secretary, while maintaining an annulus pressure different from atmospheric pressure measured at the surface;

 

               (b)  Pressure test with liquid or gas; or

 

               (c)  An alternative test to demonstrate mechanical integrity other than those listed in this subdivision if it is specified in the permit or is approved by the secretary through a technical revision;

 

          (2)  One of the following methods must be used to determine the absence of significant fluid movement into any unauthorized zone, underground source of drinking water, or water-bearing strata through vertical channels adjacent to the injection bore:

 

               (a)  The results of a temperature, neutron, or noise log (e.g., cement bond log);

 

               (b)  If the nature of the casing precludes the use of the logging techniques prescribed above, sealing records demonstrating the presence of adequate sealing material to prevent such migration shall be provided; or

 

               (c)  If the secretary elects to rely on sealing records to demonstrate the absence of significant fluid movement, the monitoring program shall be designed to verify the absence of significant fluid movement;

 

          (3)  Maintenance of the mechanical integrity of each injection well that has not been plugged or converted shall be demonstrated at least once every five years or on a schedule determined by the secretary;

 

          (4)  Before resuming injection into any injection well that has been damaged by surface or subsurface activity or that has undergone an activity that may jeopardize the mechanical integrity of the well, such as the use of downhole cutting and underreaming tools, the operator must demonstrate the mechanical integrity of that well;

 

          (5)  If the secretary determines that an injection well lacks mechanical integrity, the secretary shall give written notice of this determination to the operator of the well. Unless the secretary requires immediate cessation, the operator shall cease injection into the well within 48 hours of receipt of the secretary's determination. The secretary may allow plugging of the well or require the operator to perform such additional construction, operation, monitoring, reporting, and corrective action as is necessary to prevent the movement of fluid into unauthorized zones or onto the surface caused by the lack of mechanical integrity. Repair or plugging of the well must be completed within 120 days of the testing that indicates the well lacks mechanical integrity. If the well is repaired rather than plugged, retesting of the well must be completed within 120 days after the repair is completed. The operator may resume injection upon written notification from the secretary that the operator has demonstrated mechanical integrity; and

 

          (6)  Results of mechanical integrity testing shall be reported in accordance with the requirements in § 74:55:01:49.

 

          Injection and production wells shall maintain mechanical integrity until the wells are properly plugged in accordance with the approved plugging and abandonment plan.

Rule 74:55:01:31 Well construction requirements.

          74:55:01:31.  Well construction requirements. The method for well construction shall be stated in the permit application. Construction requirements listed in this section apply to all wells installed for activities related to in situ leach mines. The secretary may grant a deviation from the requirements through a technical revision, if the operator supplies documentation of reliability, mechanical integrity, design, and construction to protect ground waters of the state. Injection and production wells shall be generally constructed as follows:

 

          (1)  Annular seals shall be installed to protect the casing against corrosion, ensure structural integrity of the casing, stabilize the well bore, protect against contamination or pollution of the well from the surface, and prevent migration of ground water from one aquifer or water-bearing strata to another in accordance with the following requirements:

 

               (a)  The drill hole shall be of sufficient diameter for adequate sealing and, at any given depth, at least three inches greater in nominal diameter than the outside diameter of the outer casing at that depth. The secretary may approve an alternative casing design if it provides an equivalent degree of ground water protection;

 

               (b)  Before placing the annular seal, the well bore shall be under static conditions and all loose drill cuttings, rock chips, or other obstructions shall be removed from the annular space by circulating the borehole with water or drilling mud slurry;

 

               (c)  The annular sealing material shall be pressure-grouted as required in § 74:02:04:28;

 

               (d)  Sealing material shall consist of neat cement grout or bentonite grout mixtures meeting the following requirements:

 

                      (i)    Cement grout shall be composed of high sulfate resistant Portland cement and shall conform to the requirements of § 74:02:04:53;

 

                      (ii)   Bentonite grout shall conform to the requirements of § 74:02:04:53.01. The bentonite grout shall be a sodium bentonite material that has been commercially manufactured and specially formulated for use as a well casing seal;

 

                      (iii)  The sealing material shall be thoroughly mixed before placement so there are no balls, clods, or other features that could reduce the effectiveness of the seal;

 

                      (iv)   Special quick-setting cement, cement accelerators, retarders, fluid-loss additives, dispersants, extenders, loss-of-circulation materials, and other additives, including hydrated lime to make the mix more fluid or bentonite to make the mix more fluid and reduce shrinkage, may be used, if approved by the secretary; and

 

                      (v)    Used drilling mud or drill cuttings from the borehole may not be used as sealing material;

 

          (2)  Well casing shall conform to the requirements of §§ 74:02:04:42 to 74:02:04:45, inclusive, and § 74:02:04:48. The casing shall be of sufficient strength and diameter to prevent casing collapse during installation, convey liquid at a specified injection/recovery rate and pressure, and allow for sampling. Casing shall be placed with sufficient care to avoid damage to casing sections and joints. All joints in the casing above the perforations or screens shall be watertight. Casing shall be equipped with centralizers placed at a maximum spacing of one per forty feet to ensure even thickness of annular seal and gravel pack; and

 

          (3)  Well development shall be done by methods that will not cause damage to the well or cause adverse subsurface conditions that may destroy barriers to the vertical movement of water between water bearing strata.

Characteristics may include aquifer thickness, velocity and direction of ground water movement, storage coefficients or specific yields, transmissivity or hydraulic conductivity, and the directions of preferred flow under hydraulic stress in saturated zones of the receiving strata. The plan shall include potentiometric maps of the ground water surface in the receiving strata and overlying and underlying aquifers. The extent of hydraulic connection between the receiving strata and overlying and underlying aquifers and the hydraulic characteristics of any influencing boundaries in or near the proposed production areas shall be determined and described. Water samples shall not be taken until the specific conductivity, temperature, and pH have stabilized. These samples shall be analyzed for the parameters designated by the secretary. All baseline wells shall be sampled at least once every month for a minimum of six months before any mining activities. If a well shows results indicating a statistically significant variance for a control parameter, whether due to laboratory error or natural fluctuation, the secretary may require additional samples be taken. The sample results for each well shall be submitted to the secretary.

 

          The secretary shall consider the baseline water quality values for a production area to determine the upper limit value of a control parameter which, when exceeded, indicates that an injected fluid may be present. All samples shall be collected, preserved, analyzed, and controlled according to accepted methods.
