HAR §11-45-228. Radiation surveys

(a) Radiation surveys or calculations shall be made and recorded for each area where radioactive materials are used and stored. (b) Radiation surveys shall be made and recorded for the radiation levels in occupied positions and on the exterior of each vehicle used to transport radioactive material. Such surveys shall include each source of radiation or combination of sources to be transported in the vehicle. (c) If the sealed source assembly is removed from the logging tool before departing the jobsite, the logging tool detector shall be energized, or a survey meter used, to assure that the logging tool is free of contamination. (d) Radiation surveys shall be made and recorded at the jobsite or well-head for each tracer operation. These surveys shall include measurements of radiation levels before and after the operation. (e) Records required pursuant to subsections (a) through (d) shall include the dates, the identification of individual(s) making the survey, the identification of survey instrument(s) used, and an exact description of the location of the survey. Records of these surveys shall be maintained for inspection by the department for three years.

Each licensee shall maintain, for inspection by the department, the following documents and records for the specific devices and sources used at the field station: (1) License; (2) Operating and emergency procedures; (3) Chapter 11-45; (4) Records of the latest survey instrument calibrations pursuant to section 11-45-213; (5) Records of the latest leak test results pursuant to section 11-45-214; (6) Records of quarterly inventories required pursuant to section 11-45-215; §11-45-231 45-163 (7) Utilization records required pursuant to section 11- 45-216; (8) Records of inspection and maintenance required pursuant to section 11-45-219; (9) Survey records required pursuant to section 11-45-228; and (10) Training records required pursuant to section 11-45- 221.

Each licensee conducting operations at a temporary jobsite shall have the following documents and records available at that site for inspection by the department: (1) Operating and emergency procedures; (2) Survey records required pursuant to section 11-45-228 for the period of operation at the site; (3) Evidence of current calibration for the radiation survey instruments in use at the site; (4) Copy of license; and (5) Shipping papers for the transportation of radioactive material.

(a) Notification of incidents and sources lost in other than downhole logging operations shall be made in accordance with appropriate provisions of subchapter 4. (b) Whenever a sealed source or device containing radioactive material is lodged downhole, the licensee shall: (1) Monitor at the surface for the presence of radioactive contamination with a radiation survey instrument or logging tool during logging tool recovery operations; and (2) Notify the department immediately by telephone and subsequently, within thirty days, by confirmatory letter if the licensee knows or has reason to believe that a sealed source has been ruptured. This letter shall identify the well or other location, describe the magnitude and extent of the escape of radioactive material, assess the consequences of the rupture, and explain efforts planned or being taken to mitigate these consequences. (c) When it becomes apparent that efforts to recover the radioactive source shall not be successful, the licensee shall (1) Advise the well-operator of an appropriate method of abandonment, which shall include: (A) The immobilization and sealing in place of the radioactive source with a cement plug, (B) The setting of a whipstock or other deflection §11-45-231 45-164 device, and (C) The mounting of a permanent identification plaque at the surface of the well, containing the appropriate information required by subsection (d); (2) Notify the department by telephone, giving the circumstances of the loss, and request approval of the proposed abandonment procedures; and (3) File a written report with the department within thirty days of the abandonment. The licensee shall send a copy of the report to the agency who issued permits or otherwise approved of the drilling operation. The report shall contain the following information: (A) Date of occurrence; (B) A description of the well logging source involved, including the radionuclide and its quantity, chemical, and physical form; (C) Surface location and identification of the well; (D) Results of efforts to immobilize and seal the source in place; (E) A brief description of the attempted recovery effort; (F) Depth of the source; (G) Depth of the top of the cement plug; (H) Depth of the well; (I) Any other information, such as a warning statement, contained on the permanent identification plaque; and (J) The names of state agencies receiving a copy of this report. (d) Whenever a sealed source containing radioactive material is abandoned downhole, the licensee shall provide a permanent plaque for posting the well or well-bore. This plaque shall: (1) Be constructed of long-lasting material, such as stainless steel or monel; and (2) Contain the following information engraved on its face: (A) The word "CAUTION"; (B) The radiation symbol without the conventional color requirement; (C) The date of abandonment; (D) The name of the well-operator or well-owner; (E) The well name and well identification number(s) or other designation; (F) The sealed source(s) by radionuclide and activity; (G) The source depth and the depth to the top of the plug; and (H) An appropriate warning, depending on the specific circumstances of each abandonment. (e) The licensee shall immediately notify the department by telephone and subsequently by confirming letter if the licensee §11-45-233 45-165 knows or has reason to believe that radioactive material has been lost in or to an underground potable aquifer. Such notice shall designate the well location and shall describe the magnitude and extent of loss of radioactive material, assess the consequences of such loss, and explain efforts planned or being taken to mitigate these consequences.
