Each licensee shall:
(a) Operate in accordance with the requirements and objectives of 10 C.F.R. Part 40, Appendix A, and this Chapter, including the procedures required by Section 9(f) and the monitoring required by Section 9(g).
(b) Submit a semi-annual report to the Department within sixty (60) days following January 1 and July 1 of each year. The report must specify the quantity of each of the principal radionuclides released to unrestricted areas in liquid and in gaseous effluents during the previous six months of operation, and such other information as the Department may require to estimate the maximum potential annual radiation doses to the public resulting from effluent releases. If quantities of radioactive materials released during the reporting period are significantly above the licensee's design objectives previously reviewed as part of the most recent licensing action, the report shall cover this specifically. On the basis of such reports or any additional information the Department may obtain from the licensee or others, the Department may require the licensee to take such actions as the Department deems appropriate to protect public health and safety and the environment.
(c) Licensee shall report events that have significant radiological effects on employee safety, public health, or the environment to the Department according to the following: - (i) All licensees shall notify the Department as soon as possible but no later than four (4) hours after the discovery of an event that prevents immediate protective actions necessary to avoid exposure to radiation or licensed materials that could exceed regulatory limits (events may include fires, explosions, toxic gas releases, etc.). The following events require immediate notification to the Department:
- (A) Any failure in a tailings or waste retention system which results in a release of tailings or waste into unrestricted areas; and
- (B) Any unusual conditions which are not contemplated in the design of the retention system and which if not corrected could lead to failure of the system and result in a release of tailings or waste into unrestricted areas.
- (ii) Each licensee shall notify the Department within twenty-four (24) hours after the discovery of any of the following events involving licensed material:
- (A) An unplanned contamination event that:
- (I) Requires access to the contaminated area, by workers or the public, to be restricted for more than twenty-four (24) hours by imposing additional radiological controls or by prohibiting entry into the area;
- (II) Involves a quantity of material greater than five times the lowest annual limit on intake specified in 10 C.F.R. Part 20, Appendix B; and
- (III) Requires access to the area restricted for a radiological safety reason other than to allow isotopes with a half-life of less than twenty-four (24) hours to decay prior to decontamination.
- (B) An event in which equipment is disabled or fails to function as designed when:
- (I) The equipment is required by regulation or license condition to prevent releases exceeding regulatory limits, to prevent exposures to radiation and radioactive materials exceeding regulatory limits, or to mitigate the consequences of an accident;
- (II) The equipment is required to be available and operable when it is disabled or fails to function; and
- (III) No redundant equipment is available and operable to perform required safety function.
- (C) An event that requires unplanned medical treatment at a medical facility of an individual with spreadable radioactive contamination on the individual's clothing or body;
- (D) An unplanned fire or explosion damaging any licensed material or any device, container, or equipment containing licensed material when:
- (I) The quantity of material involved is greater than five times the lowest annual limit on intake specified in 10 C.F.R. Part 20, Appendix B.
- (II) The damage affects the integrity of the licensed material or its container.
- (iii) Reporting of spills of licensed material and excursions shall be done pursuant to Chapter 11 of the Non-Coal Rules and Regulations.
- (iv) Reports made by the licensees in response to the requirements of this section must be made as follows:
- (A) Licensees shall make reports required by Sections 10(c)(i) and 10(c)(ii) of this Chapter by telephone to the Department. To the extent that the information is available at the time of notification, the information provided in these reports must include:
- (I) The caller's name and call back telephone number;
- (II) A description of the event, including date and time;
- (III) The exact location of the event;
- (IV) The isotopes, quantities, and chemical and physical form of the licensed material involved; and
- (V) Any personnel radiation exposure data available.
- (B) Licensees who make a report required by Section 10(c)(iii) of this Chapter shall submit a written follow-up report as prescribed in Chapter 11 of the Non-Coal Rules and Regulations.
- (C) Written reports prepared pursuant to other applicable rules may be submitted to fulfill this requirement if the reports contain all of the necessary information and the appropriate distribution is made. The reports must include the following:
- (I) A description of the event, including the probable cause and the manufacturer and model number (if applicable) of any equipment that failed or malfunctioned;
- (II) The exact location of the event;
- (III) A description of the isotopes, quantities, and chemical and physical form of the licensed material involved;
- (IV) Date and time of the event;
- (V) Corrective actions taken or planned and the result of any evaluations or assessments;
- (VI) Timely schedule for remediation of the spill or release, if required; and
- (VII) The extent of exposure of individuals to radiation or to radioactive materials without identification of the individuals by name.
