      (1)   A map of the well site, showing all equipment to be used there, location of pipelines, access road and distances from the well to any and all fences, public roadways and buildings within a radius of 1,000 feet;
      (2)   A map of the project showing the location of all supply, disposal, injection and producing wells; all conduits; tank battery, pumping station and appurtenant equipment; all wells in the project area and those located in the sections immediately adjacent to include producing, abandoned, plugged and abandoned, disposal and public or private fresh water supply wells;
      (3)   Evidence that all wells in the area of the project and adjacent section were plugged and abandoned in compliance with Corporation Commission regulations at the time the well was plugged and abandoned;  (A plugging record (OCC Form 9003) to demonstrate compliance is acceptable.)
      (4)   All wells associated with the project shall be indicated by status (e.g., plugged and abandoned (P&A), abandoned, injector, source well, producer, idle and the like) and showing the additional information:
         (a)   Surveyed surface location;
         (b)   DF or KB elevation;
         (c)   Drilled total depth;
         (d)   PBTD;
         (e)   Size, depth and grade of surface and production casing;
         (f)   Location of all plugs, packers, cement plugs, tubing anchors and the like within the well bore;
         (g)   Depth and nature of all cement squeeze jobs;
         (h)   Formation name and depth of all open perforations and open hole interval;
         (i)   Volume and type of cement used on surface and production strings; and
         (j)   Top of cement behind pipe.
      (5)   One copy of all electric, mechanical, sample and driller’s log, if available;

      (10) Copies of the Corporation Commission Form No. 1015, indicating successful pressure testing of each injection well at a pressure greater than the maximum proposed for the project, or if no the form has been filed and approved, then sufficient evidence of the successful pressure testing of each injection well.
   (B)   Upon the completion of the application required hereunder, the City Manager or his or her designee shall have 30 business days to review same and make a recommendation of approval or disapproval to the City Council.
   (C)   A fee in the sum of $1,000 shall be submitted along with every application required hereunder.
   (D)   Where an existing well is to be used as an injection or disposal site, the existing casing and cement shall be of an integrity and depth as to adequately and safely isolate fresh water producing zones from the seepage and bleeding of injection fluids or disposants.  Where additional protective operations are undertaken to comply with this section, the City Manager or his or her designee shall be notified thereof sufficiently in advance in order for him or her to be present for the operations.
   (E)   Injection lines shall be buried in a trench at a depth no less than four feet, below grade level and shall be pressure tested annually at a minimum of 150% of the pressure normally encountered at the injection pump discharge for a period of hours to be fixed by the City Manager or his or her designee.  They shall be notified five business days in advance of the test and may supervise same.  Test results shall be filed with the city upon completion.
   (F)   Fresh water wells located within a radius of 1,000 feet of any enhanced recovery or disposal well shall be tested semi-annually for the presence of deleterious substances, such as chloride, sulphates and dissolved solids.  If any enhanced recovery or disposal well is not being used for injection or disposal purposes and is in compliance with OCC rule 3-305, (Testing and Monitoring Requirements for Enhanced Recovery Injection Wells; and Disposal Wells), the City Manager or his or her designee may waive the testing of fresh water wells located within the 1,000-foot radius of the inactive well.  The testing is the responsibility of the permittee and permittee’s expense.  The City Manager or his or her designee shall be notified five business days in advance of the testing and may be present therefor.  Test results shall be filed with the city upon completion.
