(6) Geologic name and depth to bonom of all underground sources of drinking water which may be affected by the injection; (71 Schematic or other appropriate drawings of the surface and subsurface constmction details of she well; (8) In the case of new injection wells the ror- rcetive action proposed to be taken by the appli- cant under 40 CFR I?2.44; (9) A certificate that the applicam has assured through a performance bond or other appropriate means, the resources necessary Io close plug or abandon the well as required by 40 CFR 12'-.4216): (b) In addition the Director may consider the following: (I) Proposed formation testing program to ob- tain the in(omlation required by ¢ 146.22(8). (?) Proposed stimulation program; (31 Proposed injection procedure; (4) Proposed comingeney plans, i( any, Io cope with well failures so as to preerm nugrmion of comaminaling Fluids into an underground source of drinking water; (5) Plans for meeting the monitoring requirc~ meets o(§ 146:?316). (c) Prior to gmming approval (or the optmtion of a Class II well the Direcmr shall consider the following information: (U All available logging and testing program data on the well; (?) A demonstration of mechanical imegosy pursuant m § 146.8: (?) The anticipated maximum pressure and flow rate m which Ihr pernuure wdl operate.

This subpart establishes criteria and standards for underground mjtcuan control programs to reg- ulate Class III wells. § 146.32 Construction requirements (a) All new Class 111 wells shall bt cased and cemented to prevem the migmtian of Omds into or between underground sources of dnnking water. The Director may waive the cementing require- ment (or new wells in existing pro)ects or portions of existing projects where he has substantial eei- dence Thal no contamination of underground sources of drinking water would resuh. The casing and cemem used in the constmction o(each newly drilled well shall be designed for the life expect ancy of the well In detenninmg and sprn(ymg rasing and cementing requirements, the fallowing (actors shall be considered: (I) Depth to the injection zone; (?) Injection pressure, external pressure, internal pressure, axial loading, etc.: (?) Holr size: (4) Size and grade of all casing strings (wall Ihi<kness, diameter, nominal weighs, length, join) specification, and construction mmeriap; (5) Corrosiveness of injected fluids and forma- tion Iuids: (6) Liihology of injection and confining zones; and (7) Type and grade of cement. (h) Appropnate logs and ocher tests shall br conducted during she drilling and constmction of new Class III wells A descriptive report interpret- ing Ihr results of such logs and Itsts shall be prc- parcd by a knowledgeable log analyst and submil- ttd to the Dlrcctor. The logs and sees approprime to each sype of Class III well shall be detrmiined based on she imended (unction, depth, conswnion and other chamcterisucs of she well, availabdisy of similar data m the area of the drilling site and the need (or additional information that may arise from time to time as the constiuclion of Ihr well progresses. Deviation checks shall be conducted on all hosts where pilot holes and rearrung are used, unless she hole wdl be cased and cemrmed by circulating cement to Ihr surface. Where devi- ation checks arc necessary they shall be conducted al su(ticiently frequem intervals to assure Ihm ver- sical avenues (or Iluid migrasion in the form of di- verging holes arc not created during drillings. 13
