E. NAME AND DEPTH OF USDWs (CLASS II) - For Class II wells, submit geologic name, and depth to bottom of all
<br /> underground sources of drinking water which may be affected by the injection.
<br /> F. MAPS AND CROSS SECTIONS OFGEOLOGICSTRUCTURE OFAREA-Submit maps and cross sections detailing the
<br /> geologic structure ofthe local area(including the lithology of injection and confining intervals)and generalized maps
<br /> and cross sections illustrating the regional geologic setting. (Does not apply to Class II wells.)
<br /> G. GEOLOGICAL DATA ON INJECTION AND CONFINING ZONES (Class II) - For Class II wells, submit appropriate
<br /> geological data on the injection zone and confining zones including lithologic description,geological name,thickness,
<br /> depth and fracture pressure.
<br /> H. OPERATING DATA-Submit the following proposed operating data foreach well(including all those to be covered by
<br /> area permits):(1)average and maximum dailyrate and volumeofthe fluids to be injected; (2)average and maximum
<br /> injection pressure; (3) nature of annulus fluid; (4)for Class I wells, source and analysis of the chemical, physical,
<br /> radiological and biological characteristics, including density and corrosiveness, of injection fluids; (5)for Class II
<br /> wells, source and analysis of the physical and chemical characteristics of the injection fluid; (6)for Class III wells, a
<br /> qualitative analysis and ranges in concentrations ofall constituents of injected fluids. If the information is proprietary,
<br /> maximum concentrations only may be submitted, but all records must be retained.
<br /> I. FORMATION TESTING PROGRAM -Describe the proposed formation testing program.For Class I wells the program
<br /> must be designed to obtain data on fluid pressure, temperature,fracture pressure, other physical, chemical, and
<br /> radiological characteristics of the injection matrix and physical and chemical characteristics of the formation fluids.
<br /> For Class 11 wells the testing program must be designed to obtain data on fluid pressure, estimated fracture
<br /> pressure, physical and chemical characteristics of the injection zone. (Does not apply to existing Class 11 wells or
<br /> projects.)
<br /> For Class III wells the testing must be designed to obtain data on fluid pressure,fracture pressure, and physical and
<br /> chemical characteristics of the formation fluids if the formation is naturally water bearing. Only fracture pressure is
<br /> required if the program formation is not water bearing. (Does not apply to existing Class III wells or projects.)
<br /> J. STIMULATION PROGRAM -Outline any proposed stimulation program.
<br /> K. INJECTION PROCEDURES-Describe the proposed injection procedures including pump, surge,tank, etc.
<br /> L. CONSTRUCTION PROCEDURES-Discuss the construction procedures(according to§146.12 forC1ass1,§146.22 for
<br /> Class 11, and §146.32 for Class 111)to be utilized. This should include details of the casing and cementing program,
<br /> logging procedures, deviation checks, and the drilling, testing and coring program, and proposed annulus fluid.
<br /> (Request and submission of justifying data must be made to use an alternative to packer for Class 1.)
<br /> M. CONSTRUCTION DETAILS-Submit schematic or other appropriate drawings of the surface and subsurface
<br /> construction details of the well.
<br /> N. CHANGES IN INJECTED FLUID-Discuss expected changes in pressure, native fluid displacement, and direction of
<br /> movement of injection fluid. (Class III wells only.)
<br /> O. PLANS FOR WELL FAILURES-Outline contingency plans(proposed plans, if any,for Class ll)to cope with all
<br /> shut-ins or wells failures, so as to prevent migration of fluids into any USDW.
<br /> P. MONITORING PROGRAM - Discuss the planned monitoring program. This should be thorough, including maps
<br /> showing the number and location of monitoring wells as appropriate and discussion of monitoring devices,sampling
<br /> frequency, and parameters measured. If a manifold monitoring program is utilized, pursuant to §146.23(b)(5),
<br /> describe the program and compare it to individual well monitoring.
<br /> Q. PLUGGING AND ABANDONMENT PLAN - Submit a plan for plugging and abandonment of the well including: (1)
<br /> describe the type, number, and placement(including the elevation of the top and bottom)of plugs to be used; (2)
<br /> describe the type, grade, and quantity of cement to be used;and (3)describe the method to be used to place plugs,
<br /> including the method used to place the well in a state of static equilibrium prior to placement of the plugs.Also for a
<br /> Class III well that underlies or is in an exempted aquifer,demonstrate adequate protection of USDWs. Submit this
<br /> information on EPA Form 7520-14, Plugging and Abandonment Plan.
