This plaque shall meet the following requirements: (A) be constructed of long-lasting material such as stainless steel, brass, bronze, or monel. The size of the plaque should be convenient for use on active or inactive wells; for example, a 7-inch (17 cm) square. Letter size of the word "CAUTION" should be approximately twice the letter size of the rest of the information; for example, 1/2 inch (1.27 cm) and 1/4 inch (0.63 cm) letter size, respectively; and(B) contain the following engraved information on its face: (ii) the radiation symbol (color not required);(iii) the date of abandonment;(iv) the name of the well operator or well owner;(v) the well name and well identification number(s) or other designation;(vi) radionuclide(s) and activity(ies) of the source(s);(vii) the source depth and the plug back depth (depth to the top of the plug); and(viii) an appropriate warning, depending on the specific circumstances of each abandonment, such as the following: (I) "Do not drill below plug back depth;"(II) "Do not enlarge casing;" or(III) "Do not re-enter hole before contacting Radiation Control, Texas Department of State Health Services."(7) The licensee shall immediately notify the agency by telephone and confirming letter if the licensee knows or has reason to believe that radioactive material has been lost in or to an underground potable water source. Such notice shall designate well location and describe the magnitude and extent of loss of radioactive material, consequences of such loss and efforts taken or planned to mitigate these consequences.(8) In the event of an uncontrolled release of radioactive tracer material to the environment, the licensee shall notify the agency by telephone within 24 hours and submit written notification within 30 days.(ee) Appendices. (1) Subjects to be included in training courses for well logging service operations and/or tracer studies are as follows: (A) fundamentals of radiation safety that include: (i) characteristics of radiation;(ii) units of radiation dose (rem) and activity;(ii) units of radiation dose (rem) and activity;(iii) significance of radiation dose specifying radiation protection standards and biological effects of radiation;(iv) levels of radiation from sources of radiation;(v) methods of controlling radiation dose specifying time, distance, and shielding;(vi) radiation safety practices, specifying prevention of contamination and methods of decontamination; and(vii) discussion of ingestion, inhalation pathways;(B) radiation detection instrumentation to be used that includes: (i) use of radiation survey instruments specifying operation, calibration, and limitations;(ii) survey techniques; and(iii) use of individual monitoring devices;(C) equipment to be used that specifies; (i) handling equipment and remote handling tools;(ii) sources of radiation;(iii) storage control, disposal, and transport of equipment and sources of radiation;(iv) operation and control of equipment; and(v) maintenance of equipment;(D) pertinent federal and state requirements;(E) the licensee's or registrant's written operating, safety, and emergency procedures;(F) the licensee's or registrant's record keeping procedures; and(G) case histories and potential consequences of accidents in well logging service operations and tracer studies.(2) In addition to the subjects for training courses required in paragraph (1) of this subsection, individuals performing tracer studies must also complete training in the following subjects: (A) sources of contamination;(B) contamination detection and control;(C) decontamination techniques and limits;(D) survey techniques for tracer materials; and(E) packaging requirements for transportation of radioactive materials, especially residual materials from tracer studies.(3) The following is an example of a plaque for identifying wells containing sealed sources of radioactive material abandoned downhole: Attached Graphic
(4) The licensee's or registrant's operating, safety, and emergency procedures shall include descriptions of and instructions in at least the following: (A) the handling and use of sources of radiation in wells without surface casing for protecting fresh water aquifers, if appropriate;(B) the handling and use of sources of radiation to be employed so that no individual is likely to be exposed to radiation doses in excess of the limits established in § 289.202 of this title, or § 289.231 of this title, as applicable. Every reasonable effort shall be made to keep radiation exposures and releases of radioactive material in soils and effluents to unrestricted areas as low as is reasonably achievable;(C) methods and occasions for conducting radiation surveys;(D) methods and occasions for locking and securing sources of radiation;(E) personnel monitoring, including bioassays, and the use of individual monitoring devices;(F) removal of radioactive material from storage, transportation of radioactive material to field locations and temporary job sites, including packaging of sources of radiation in the vehicles, placarding of vehicles, securing sources of radiation during transportation, and return to storage;(G) minimizing exposure of individuals during routine use and in the event of an accident;(H) procedures for notifying proper personnel in the event of an accident or well excursion;(I) maintenance of records;(J) use, inspection, and maintenance of source holders, logging tools, source handling tools, storage containers, transport containers, and injection tools;(K) procedures to be followed in the event a sealed source is lost or lodged downhole;(L) procedures to be used for picking up, receiving, handling, and opening packages containing radioactive material;(M) procedures to be used for surveys of temporary job sites and equipment, and decontamination of vehicles, associated equipment, and clothing following tracer studies;(N) storage and disposal of radioactive waste;(O) procedures for laundering contaminated clothing, if applicable;(P) licensee's or registrant's management structure;(Q) posting of radiation areas and labeling radioactive material containers;(R) procedures to be followed in the event of an uncontrolled release of radioactive tracer material to the environment; and(S) actions to be taken if a sealed source is ruptured, including actions to prevent the spread of contamination and minimize inhalation and ingestion of radioactive material, and actions to obtain suitable radiation survey instruments as required by subsection (i) of this section.(5) The following records/documents shall be maintained by the licensee or registrant for inspection by the agency.
